Infants acquire their first words through interactions with social partners. In the first year of life, infants receive a high frequency of visual and auditory input from faces, making faces a potential strong social cue in facilitating word-to-world mappings. In this position paper, we review how and when infant gaze to faces is likely to support their subsequent vocabulary outcomes. We assess the relevance of infant gaze to faces selectively, in three domains: infant gaze to different features within a face (...) ; then to faces ; and finally to more socially relevant types of faces. We argue that infant gaze to faces could scaffold vocabulary construction, but its relevance may be impacted by the developmental level of the infant and the type of task with which they are presented. Gaze to faces proves relevant to vocabulary, as gazes to eyes could inform about the communicative nature of the situation or about the labeled object, while gazes to the mouth could improve word processing, all of which are key cues to highlighting word-to-world pairings. We also discover gaps in the literature regarding how infants’ gazes to faces or to different types of faces relate to vocabulary outcomes. An important direction for future research will be to fill these gaps to better understand the social factors that influence infant vocabulary outcomes. (shrink)

During the postpartum period, the paternal brain suffers extensive and complex neurobiological alterations, through the experience of father–infant interactions. Although the impact of such experience in the mother has been increasingly studied over the past years, less is known about the neurobiological correlates of fatherhood—that is, the alterations in the brain and other physiological systems associated with the experience of fatherhood. With the present study, we aimed to perform a scoping review of the available literature on the (...) genetic, neuroendocrine, and brain correlates of fatherhood and identify the main gaps in the current knowledge. PubMed, Scopus, and Web of Science electronic databases were searched for eligible studies on paternal neuroplasticity during the postpartum period, over the past 15 years. Reference lists of relevant key studies and reviews were also hand-searched. The research team independently screened the identified studies based on the established inclusion criteria. Extracted data were analyzed using tables and descriptive synthesis. Among the 29 studies that met our inclusion criteria, the vast majority pertained to neuroendocrine correlates of fatherhood, followed by brain activity or connectivity, association studies of candidate genes, and brain structure correlates. Collectively, studies published during the past 15 years suggest the existence of significant endocrine and neurofunctional alterations as a result of fatherhood, as well as preliminary evidence of genetic variability accounting for individual differences during the postpartum period in fathers. No studies were so far published evaluating epigenetic mechanisms associated with the paternal brain, something that was also the focus of the current review. We highlight the need for further research that examines neuroplasticity during the experience of fatherhood and that considers both the interplay between hormones and simultaneous assessment of the different biomarkers ; data collection protocols and assessment times should also be refined.

Objective:To characterize the prevalence of hyperpalatable foods (HPF) among baby foods in the U.S. and examine the prevalence of HPF exposure and consumption from both baby food and adult food sources among infants aged 9–15 months.Methods:A U.S. baby food database as well as baby foods from three 24-h dietary recalls of 147 infants were used to identify baby foods as HPF per previous publication. HPF exposure was defined as intake of any HPF during the 3-day measurement period. To determine (...) the extent of HFP consumption, % kilocalorie (kcal) intake from HPF was characterized.Results:Only 12% of baby foods were HPF; however, nearly all participants (>90%) consumed HPF, primarily through exposure to adult foods. Younger infants (<12 months) consumed 38% [standard deviation (SD) = 23.6%] of their daily food kcal from HPF and older infants (≥12 months) consumed 52% (SD = 16.4%) of daily food kilocalorie from HPF. Most younger infants (68%) and older infants (88%) had repeated exposure to the same HPF across the measurement period.Conclusions:The prevalence of HPF among baby foods in the U.S. is low. However, almost all infants were exposed to HPF, and HPF comprised a substantial percentage of daily food kilocalorie in infants' diets. Findings highlight the transition to solid food consumption during complimentary feeding period is a critical time for early HPF exposure. (shrink)

Developmental psychologists assume that infants understand other persons’ actions after and because they understand their own. However, there is another possibility as well, namely that infants come to understand their own actions after and because they understand other persons’ actions. We reviewed infant research on the influence of perceived actions on self-performed actions as well as the reverse. Furthermore, we investigated the interplay between both aspects of action understanding by means of a sequence variation. The results show the impact of (...) agentive experience for action understanding, but not the reverse. The question whether infants’ perceived and to-be-produced actions share common representations of the perceptual and the motor system is discussed in relation to its implications for the social making of minds.

In this article, we review empirical evidence regarding the relationship between facial expression and emotion during infancy. We focus on differential emotions theory’s view of this relationship because of its theoretical and methodological prominence. We conclude that current evidence fails to support its proposal regarding a set of pre-specified facial expressions that invariably reflect a corresponding set of discrete emotions in infants. Instead, the relationship between facial expression and emotion appears to be more complex. Some facial expressions may (...) have different meanings in infants than in children and adults. In addition, nonemotion factors may sometimes lead to the production of “emotional” facial expressions. We consider alternative perspectives on the nature of emotion and emotional expression in infancy with particular focus on differentiation and dynamical systems approaches. (shrink)

According to evolutionary, genetic, and endocrinal perspectives, gender differences are modulated by the interaction between intra-uterine stress, genetic equipments, and the availability of the facilitating environment during the newborn period. The social message of fitness over obstacles during socialization and the discussion of secure/non-secure attachment styles should take into consideration the brain functions, which are altered differently in response to intra- and extra-uterine stress in each gender.

We argue for the importance of looking at the microbiota-gut-brain axis from a human developmental perspective. For this purpose, we first briefly highlight emerging research with infants attesting that the microbiome plays a role in early brain and cognitive development. We then discuss the use of developmentally informed humanized mouse models and implications of microbiome research that go beyond probiotic administration.

From birth to 15 months infants and caregivers form a fundamentally intersubjective, dyadic unit within which the infant’s ability to recognize gender/sex in the world develops. Between about 18 and 36 months the infant accumulates an increasingly clear and subjective sense of self as female or male. We know little about how the precursors to gender/sex identity form during the intersubjective period, nor how they transform into an independent sense of self by 3 years of age. In this Theory (...) and Hypothesis article I offer a general framework for thinking about this problem. I propose that through repetition and patterning, the dyadic interactions in which infants and caregivers engage imbue the infant with an embodied, i.e., sensori-motor understanding of gender/sex. During this developmental period (which I label Phase 1) gender/sex is primarily an intersubjective project. From 15 to 18 months (which I label Phase 2) there are few reports of newly appearing gender/sex behavioral differences, and I hypothesize that this absence reflects a period of developmental instability during which there is a transition from gender/sex as primarily inter-subjective to gender/sex as primarily subjective. Beginning at 18 months (i.e., the start of Phase 3), a toddler’s subjective sense of self as having a gender/sex emerges, and it solidifies by 3 years of age. I propose a dynamic systems perspective to track how infants first assimilate gender/sex information during the intersubjective period (birth to 15 months); then explore what changes might occur during a hypothesized phase transition (15 to 18 months), and finally, review the emergence and initial stabilization of individual subjectivity-the period from 18 to 36 months. The critical questions explored focus on how to model and translate data from very different experimental disciplines, especially neuroscience, physiology, developmental psychology and cognitive development. I close by proposing the formation of a research consortium on gender/sex development during the first 3 years after birth. (shrink)

Men's passage to fatherhood: an analysis of the contemporary relevance of transition theory This paper presents a theoretical analysis of men's experiences of pregnancy, birth and early fatherhood. It does so using a framework of ritual transition theory and argues that despite its earlier structural‐functionalist roots, transition theory remains a valuable framework, illuminating contemporary transitions across the life course. The paper discusses the historical development of transition or ritual theory and, drawing upon data generated during longitudinal ethnographic (...) interviews with men undergoing the transition to fatherhood, analyses its relevance in understanding contemporary experiences of fatherhood.

This paper describes the meaning of a father’s presence with a full-term healthy child delivered by caesarean section, as observed during the routine post-operative separation of mother and child. Videotaped observations recorded at a maternity clinic located in the metropolitan area of Stockholm, Sweden formed the basis for the study, in which fifteen fathers with their infants participated within two hours of elective caesarean delivery in the 37th - 40th week of pregnancy. A phenomenological analysis based on Giorgi’s method (...) was conducted on the data. The description of the new father’s experiences that emerged pointed to a process of being and becoming in taking the child to himself. Fatherhood developed gradually as a result of recurrent experiences of the child’s expressions. There was an ebb and flow between taking on the role of being a father and physical withdrawal from the role. The findings of this study not only confirm previous accounts of new fathers’ experiences, but go further in revealing an ebb and flow variation in the fathers’ involvement. What this indicates is that the process of transition to fatherhood requires not only presence but time. The period required for this process thus must not be disturbed, but supported, trusting in the father’s ability to assume his role as a father. It is suggested that, in addition to their relevance in guiding the attitudes and expectations of those professionally involved in postnatal care and community health, these findings could be useful in antenatal courses for parents, and especially in instances when caesarean birth is planned, to highlight the meaning of the role of fathers as caregivers.

The present study examined the role of father sensitivity and couple coparenting quality in the first 2 years of life in relation to the development of externalizing behavior problems in middle childhood, focusing on the unique role of fathers. In this study, 125 mothers, fathers, and their first-born children were followed from 8 months to age 7 years. Paternal sensitivity was rated when infants were 8 and 24 months old. Fathers were videotaped at home playing, feeding, and changing their 8-month-old (...) infants’ clothes. They also were videotaped in a lab playing with their 24-month-olds and solving a variety of challenging tasks. At 24 months, competitive coparenting was assessed via videotaped triadic family interactions at home in which families participated in a variety of tasks. Teachers rated externalizing behavior problems when the children were age 7. Continuity in paternal sensitivity was documented from 8 to 24 months, and paternal sensitivity at 8 months predicted externalizing behavior in middle childhood through father sensitivity at 24 months. Moreover, paternal sensitivity at 8 months predicted competitive coparenting which, in turn, forecast externalizing behavior problems in middle childhood, even after controlling for maternal sensitivity at 8 and 24 months. These findings highlight the unique role of paternal caregiving quality during the first year of life on couple coparenting and children’s subsequent development of externalizing problems and have implications for creating effective interventions to prevent children from developing externalizing disorders.

One approach to understanding model-based reasoning in science is to examine how it develops during infancy, childhood, and adolescence. The way in which thinking changes sometimes provides clues to its nature. This paper examines cognitive developmental aspects of modeling practices and discusses how a developmental perspective can enrich the study of model-based scientific reasoning in adults. The paper begins with issues concerning developmental change, followed by a model of model-based reasoning. The rest of the paper describes how several (...) key concepts from recent developmental work could contribute to current work on model-based reasoning. Specifically, developmental research shows that (a) social processes are involved in model-based reasoning and scientific discovery, (b) the development of a theory of mind contributes to the development of scientific reasoning, (c) changes in scientific reasoning are characterized by cognitive variability, and (d) microgenetic methods could clarify conceptual change during model-based reasoning.

SummaryDuring the 1920s and 1930s, Italian physicists established strong relationships with scientists from other European countries and the United States. The career of Bruno Rossi, a leading personality in the study of cosmic rays and an Italian pioneer of this field of research, provides a prominent example of this kind of international cooperation. Physics underwent major changes during these turbulent years, and the traditional internationalism of physics assumed a more institutionalized character. Against this backdrop, Rossi's early work was crucial (...) in transforming the study of cosmic rays into a branch of modern physics. His friendly relationships with eminent scientists — notably Enrico Fermi, Walther Bothe, Werner Heisenberg, Hans Bethe, and Homi Bhabha — were instrumental both for the exchange of knowledge about experimental practices and theoretical discussions, and for attracting the attention of physicists such as Arthur Compton, Louis Leprince-Ringuet, Pierre Auger and Patrick Blackett to the problem of cosmic rays. Relying on material from different archives in Europe and the United States, this case study aims to provide a glimpse of the intersection between national and international dimensions during the 1930s, at a time when the study of cosmic rays was still very much in its infancy, strongly interlaced with nuclear physics, and full of uncertain, contradictory, and puzzling results. Nevertheless, as a source of high-energy particles it became a proving ground for testing the validity of the laws of quantum electrodynamics, and made a fundamental contribution to the origins of particle physics.

In this article, I will draw on my own work and related publications to present some intuitions and hypotheses about the nature of the self and the mechanisms that lead to the development of consciousness or self awareness in human infants during the first 6 months of life. My main purpose is to show that the origins of a concept of self include the physical and the mental selves. I believe that it is essential when trying to understand what (...) a mental state is, that one identifies the social and physical aspects of the person to whom the mental state belongs. How can one identify a mental state or thought without making reference to a subject who experiences it (Hobson, 1990)? The other important feature of the self is that it is distinguished from other people and inanimate objects. ‘One's concept of self is a concept of a person; one's concept of persons cannot be a concept applicable only to a single individual (oneself), for the reason that in this case it would no longer constitute a concept'(Hobson, 1990, p. 165). I would like to argue that infants must be able to represent their physical and social selves in order to recognize that they are similar and different from other people, and to develop expectations and predictions about the behaviour of others (theory of mind). Unlike Strawson, I do not believe that the social and physical aspects of the self are, or become redundant to the nature of the self. I posit that the mature conscious self is a unique mythical and constantly changing entity, the formation of which is created not by the individual alone, but through continuous dialectical inquiry with other people.

Humans are capable of extracting recurring patterns from their environment via statistical learning (SL), an ability thought to play an important role in language learning and learning more generally. While much work has examined statistical learning in infants and adults, less work has looked at the developmental trajectory of SL during childhood to see whether it is fully developed in infancy or improves with age, like many other cognitive abilities. A recent study showed modality‐based differences in the effect (...) of age during childhood: While visual SL improved with age, auditory SL did not. This finding was taken as evidence for modality‐based differences in SL. However, since that study used auditory linguistic stimuli (syllables), the differential effect of age may have been driven by stimulus type (linguistic vs. non‐linguistic) rather than modality. Here, we ask whether age will affect performance similarly in the two modalities when non‐linguistic auditory stimuli are used (familiar sounds instead of syllables). We conduct a large‐scale study of children's performance on visual and non‐linguistic auditory SL during childhood (ages 5–12 years). The results show a similar effect of age in both modalities: Unlike previous findings, both visual and non‐linguistic auditory SL improved with age. These findings highlight the stimuli‐sensitive nature of SL and suggest that modality‐based differences may be stimuli‐dependent, and that age‐invariance may be limited to linguistic stimuli.

Remote interpreting via video-link is increasingly being employed in investigative interviews chiefly due to its apparent increased accessibility and efficiency. However, risks of miscommunication have been shown to be magnified in remote interpreting and empirical research specifically on video-link remote interpreting is in its infancy which greatly limits the evidence base available to inform and direct evidence-based policy and best practice, particularly in the identification of the optimal mode of interpreting to be used, namely consecutive and simultaneous. Consecutive interpreting (...) refers to a process in which the interpreter transfers short segments of speech from one language into the other as each person speaks in managed turn-taking, while simultaneous interpreting refers to the transfer of natural speech from one language into another in a concurrent manner without the need for speakers to segment their speech. This study provides novel empirical evidence by using eye tracking to compare the overt visual attention of interpreters working in a remote setting in which an English-speaking Interviewer interacts with a non-English-speaking Suspect in person, for whom interpretation is provided via video-link in real time. Using a within-subject design, we analyze eye-movement data from 28 professionally accredited interpreters who interpreted via video-link an investigative interview in which consecutive and simultaneous interpreting modes were counterbalanced. Taking interpreting performance into account, our results showed that, the consecutive mode yielded significantly less gaze time and therefore significantly less on-screen overt visual attention due to off-screen notetaking, an essential component of the consecutive interpreting mode. Relative to gaze time, the consecutive mode also resulted in significantly more and longer fixations and shifts of attention. Participants also allocated significantly more overt visual attention to the Interviewer than the Suspect, particularly in the consecutive mode. Furthermore, we found informative significant correlations between eye tracking measures and interpreting performance: accuracy, verbal rapport, and management. Finally, we found no significant differences between the three language pairs tested. We conclude with a discussion of limitations and the contributions of the study and an outline for future work on this topic of growing importance. (shrink)

We argue that lateralities are not merely a result of phylogenetic processes but reflect probability functions that are influenced by task characteristics and extended practice. We support our argument by empirical findings on lateral biases in early infancy in general, and footedness in particular, and on hand preferences in nonhuman primates.

The slave route from Africa to the Americas is as old as the contact between Europe and the New World itself, and the slave route across the Sahara is older still. Hence to describe the lives of ordinary people in western Africa during the era of slavery would require an examination of the whole of African history over the past five hundred years and more. And in Africa, as in Europe and the Americas, there was tremendous change over this (...) period and extensive variation at any point in time. Life in 1807, when Britain and the United States outlawed the slave trade, was considerably different than in 1492, when Columbus first sailed to the Caribbean. Hence to give an impression of how people in Africa lived during the era of transatlantic slavery is also to understand how the lives of people changed over the course of the slave trade. In 1492, a coup d’état brought a Muslim ruler, Askia Muhammad, to the throne of the great empire of Songhay, and for the next hundred years, Songhay ruled much of West Africa. As empires have always done, Songhay's influence extended to areas beyond its military control. At this time, the slavery of Africans in the Americas was in its infancy. Yet, in 1593, a military invasion from Morocco across the Sahara destroyed Songhay, and much of the internal cohesion of western Africa came to an end, precisely when transatlantic slavery emerged as the principal means of exploiting the agricultural and mineral wealth of the Americas. The lives of ordinary people changed because of this monumental collapse of Songhay. Similarly, the changes imposed by European abolition of the slave trade after 1807, although confusing and often delayed in their impact, were also monumental. Hence the first task in considering how people lived during the slavery era is to identify the differences over time that affected both people who were forced, through slavery, to cross the Atlantic and those who remained behind in Africa. Africa in 1492 or 1593 was not the same as in 1807, any more than Europe and America were. (shrink)

Exposure to pesticides during infancy is associated with numerous adverse health outcomes. The assessment of knowledge and perception of pesticides exposure and risk among children has not been thoroughly studied. The aim of the study was to evaluate the reliability and validity of a questionnaire that measures the knowledge and perception of exposure to organophosphate pesticides among rural schoolchildren. The questionnaire was administered to 151 schoolchildren between 9 and 13years from four Chilean rural schools. An internal consistency analysis (...) of the ordinal alpha coefficient and a polychoric factor analysis for categorical data were used. The results show that the ordinal alpha was 0.95. Polychoric matrices of rotated components show the 17 questions summarized pesticide knowledge in five factors extracted after promax rotation. This factorial model explains 56.3% of the variance. The questions were grouped as follows: knowledge about pesticides ; knowledge of health effects related to pesticides exposure ; pesticide exposure through the growing of fruits and vegetables ; perception and action against pesticides exposure at school ; and perception and action against pesticides exposure at home. The questionnaire provides a useful tool for examining pesticide exposure in agricultural regions, allowing younger community members to participate. (shrink)

In infancy, maternal socioeconomic status is associated with real-time language processing skills, but whether or not this relationship carries into adulthood is unknown. We explored the effects of maternal SES in college-aged adults on eye-tracked, spoken sentence comprehension tasks using the visual world paradigm. When sentences ended in highly plausible, expected target nouns, higher SES was associated with a greater likelihood of considering alternative endings related to the action of the sentence. Moreover, for unexpected sentence endings, individuals from higher (...) SES backgrounds were sensitive to whether the ending was action-related or unrelated, showing a benefit for plausible endings. Individuals from lower SES backgrounds did not show this advantage. This suggests maternal SES can influence the dynamics of sentence processing even in adulthood, with consequences for processing unexpected content. These findings highlight the importance of early lexical experience for adult language skills. (shrink)

Recent findings suggest impaired motor skill development during infancy in children later diagnosed with autism spectrum disorders (ASD). However, it remains unclear whether infants at high familial risk for ASD would benefit from early interventions targeting the motor domain. The current study investigated this issue by providing 3-month-old infants at high familial risk for ASD with training experiences aimed at facilitating independent reaching. A group of 17 high-risk (HR) infants received 2 weeks of scaffolded reaching experiences using “sticky (...) mittens,” and was compared to 72 low-risk (LR) infants experiencing the same or alternative training procedures. Results indicate that HR infants – just like LR infants – show an increase in grasping activity following “sticky mittens” training. In contrast to LR infants, evidence that motor training encouraged a preference for faces in HR infants was inconclusive. (shrink)

Basing his view on the object relations theories of the "British School" of psychoanalysis, Christopher Bollas examines the human subject's memories of its earliest experiences (during infancy and childhood) of the object, whether it be mother, father, or self. He explains in well-written and non-technical language how the object can affect the child, or "cast in shadow," without the child being able to process this relation through mental representations of language.

The cognitive revolution in the 1950s and 1960s led researchers to view the human mind--like a computer--as an information-processing system that encodes, represents, and stores information and is constrained by limits on hardware and software. The emergence of new behavioral, computational, and neuroscience methodologies, has deeply expanded psychologists' understanding of the workings of the infant, child, and adult mind. One result is that research has focused on mechanisms of change, over developmental time, in the information-processing mind.In this book, Lisa Oakes, (...) Cara Cashon, Marianella Casasola, and David Rakison bring together the recent findings and theories about the origins and early development of the information-processing mind, and provide insight into the future directions in the study of infant perception and cognition. The contributors represent a wide-range of research areas in the study of infant perception and cognition, who emphasize the use of diverse methodological techniques to address key questions about development. Their chapters demonstrate how the combination of historical perspectives on the information-processing approach to cognition and recent advances in behavioral, computational, and neuroscience approaches to cognition has contributed to our understanding of how abilities ranging from visual attention to face processing to object categorization have developed during infancy. Across this broad range of topics, it is clear that much of our modern understanding of infant perceptual and cognitive development emerges from the foundation of classic information-processing models of development, such as that of Leslie B. Cohen. The recent advances illustrated in this book show how researchers have built on this foundation to uncover the mechanisms that drive developmental change. (shrink)

Although we find many merits to Grossmann's fearful ape hypothesis, unlike Grossmann, we see heightened fearfulness as an ontogenetic adaptation, signaling helplessness and fostering caregiving during infancy, which subsequently became exapted to promote cooperation. We also argue that, rather than being the “breeding ground” for enhanced infant fearfulness, cooperative care is more likely the evolved product of enhanced fearfulness.

A population policy, that assures the negative freedom of the individuals who are not forced to proceed on abortion, their well-being and their positive freedom of escaping from preventable mortality, of avoiding mortality during infancy and childhood, of being free from hunger and undernutrition, is possible in developing countries, if the developed states should realize that they overconsume and that they use nature as their own resource, at the expense of the rest of the world.By avoiding rich nations' (...) overconsumption and injustice towards the poor ones we are moving towards a restraint on resource depletion, environmental degradation, poverty and population explosion, on the destruction of a sustainable life in general.

Aggression, violence, and cruelty are symptoms of psychiatric illness. They reflect abnormalities in the regulation of the stress and emotion circuitries. The functioning of these circuitries depends upon the interaction between genetics and environment. Abuse and neglect during infancy, as well as maternal stress and poor quality of maternal care, are some of the causes that produce these types of abnormal behavior. Research on the neurobiological bases of emotion regulation will allow the detection of the population at risk.

Using an ethnographic case study based in a UK state school for 11- to 18-year-olds, this paper explores the tensions that arose when the senior leadership team (SLT) introduced a justice-based ethic-of-care that prioritized good grades and equal treatment for all pupils over a feminist ethic-of-care (preferred by most teachers in non-leadership roles) that accentuated individual pupil need and placed greater emphasis on a broader social education. Through highlighting the tensions between a feminist ethic-of-care and a more ‘masculine’ style, justice-based (...) approach to care-ethics, the paper extends the organisational care-ethics literature. We emphasise that such tensions occurred whether the different ethics were enacted by men, women, or non-binary individuals. In order to better understand the tensions between these two ethical approaches, we draw upon the theoretical work of Donald Winnicott, which highlights the importance both of maternal and paternal roles during infancy. We update Winnicott’s ideas, noting how maternal and paternal caring roles can be undertaken by people of varied gender identities. Building on Winnicott’s theory, we propose a new ‘Parentalist’ ethic-of-care, which has the potential to balance and hold together ideas of both a feminist ethic-of-care, and a justice-based ethic. A Parentalist ethic-of-care could support teachers yet recognize the context of the contemporary neo-liberal environment, where most children need to attain formal qualifications in a marketized world, and where such measures of success are highly valued.

_Families of Virtue_ articulates the critical role of the parent-child relationship in the moral development of infants and children. Building on thinkers and scientists across time and disciplines, from ancient Greek and Chinese philosophers to contemporary feminist ethicists and attachment theorists, this book takes an effective approach for strengthening families and the character of children. Early Confucian philosophers argue that the general ethical sensibilities we develop during infancy and early childhood form the basis for nearly every virtue and (...) that the parent-child relationship is the primary context within which this growth occurs. Joining these views with scientific work on early childhood, _Families of Virtue_ shows how Western psychology can reinforce and renew the theoretical underpinnings of Confucian thought and how Confucian philosophers can affect positive social and political change in our time, particularly in such areas as paid parental leave, breastfeeding initiatives, marriage counseling, and family therapy.

Developmental psychologists have long recognized the extraordinary influence of action on learning (Held & Hein, 1963; Piaget, 1952). Action experiences begin to shape our perception of the world during infancy (e.g., as infants gain an understanding of others’ goal-directed actions; Woodward, 2009) and these effects persist into adulthood (e.g., as adults learn about complex concepts in the physical sciences; Kontra, Lyons, Fischer, & Beilock, 2012). Theories of embodied cognition provide a structure within which we can investigate the mechanisms (...) underlying action’s impact on thinking and reasoning. We argue that theories of embodiment can shed light on the role of action experience in early learning contexts, and further that these theories hold promise for using action to scaffold learning in more formal educational settings later in development.

Extrinsic mortality is a key influence on organisms’ life history strategies, especially on age at maturity. This historical longitudinal study of 125 women in rural Domenica examines effects of extrinsic mortality on human age at maturity and pace of reproduction. Extrinsic mortality is indicated by local population infant mortality rates during infancy and at maturity between the years 1925 and 2000. Extrinsic mortality shows effects on age at first birth and pace of reproduction among these women. Parish death (...) records show huge historical variation in age-specific mortality rates. The infant mortality rate (IMR) in the early 1920s was low, increased dramatically beginning in 1929, and reached a maximum in the 1950s, at which point IMR declined steadily to its present low rate. The mortality rate early in life showed a quadratic association with age at first birth. Women who experienced conditions of low IMR early in life reproduced relatively late in life. Those born into moderately high levels of infant mortality tended to reproduce earlier than those born at low levels. At very high infant mortality levels early in life, women went on to delay reproduction until relatively late, possibly as a result of somatic depletion and energetic stress associated with the conditions that lead to high IMR. Population mortality rates at age of maturity also showed a quadratic association with age at first birth. The pace of reproduction, estimated as number of surviving offspring controlled for maternal age, showed a similar quadratic effect. There were complex interactions between population mortality rates in infancy and at maturity. When extrinsic mortality was high during infancy, extrinsic mortality later in life had little effect on timing of first birth. When extrinsic mortality was low to moderate in infancy, extrinsic mortality later in life had significant effects on adult reproduction. I speculate that these effects are mediated through development of personality facets associated with reproduction. (shrink)

This study examines the family environments and hormone profiles of 316 individuals aged 2 months-58 years residing in a rural village on the east coast of Dominica, a former British colony in the West Indies. Fieldwork was conducted over an eight-year period (1988–1995). Research methods and techniques include radioimmunoassay of cortisol and testosterone from saliva samples (N=22,340), residence histories, behavioral observations of family interactions, extensive ethnographic interview and participant observation, psychological questionnaires, and medical examinations.Analyses of data indicate complex, sex-specific effects (...) of family environment on endocrine function. Male endocrine profiles exhibit greater sensitivity to presence of father than do female endocrine profiles. Father-absent males tend to have (a) low cortisol levels during infancy, (b) high or abnormal cortisol profiles during childhood and adolescence, and (c) high cortisol and low testosterone levels during adulthood compared with those of males raised with a resident father. These results indicate that early family environment has significant effects on endocrine response throughout male life histories. (shrink)

We propose a simple computational model that describes potential mechanisms underlying the organization and development of the lexical-semantic system in 18-month-old infants. We focus on two independent aspects: (i) on potential mechanisms underlying the development of taxonomic and associative priming, and (ii) on potential mechanisms underlying the effect of Inter Stimulus Interval on these priming effects. Our model explains taxonomic priming between words by semantic feature overlap, whereas associative priming between words is explained by Hebbian links between semantic representations derived (...) from co-occurrence relations between words (or their referents). From a developmental perspective, any delay in the emergence of taxonomic priming compared to associative priming during infancy seems paradoxical since feature overlap per se need not be learned. We address this paradox in the model by showing that feature overlap itself is an emergent process. The model successfully replicates infant data related to Inter Stimulus Interval effects in priming experiments and makes testable predictions. (shrink)

Humans have attained an unparalleled level of sophistication when engaging in collaborative and cooperative activities. Remarkably, the skills and motivation to engage in complex forms of collaboration and cooperation seem to emerge early on during infancy and childhood. In this paper, I extensively review the literature on the evolution and development of human cooperation, emphasizing important aspects of inter-cultural variation in collaborative and cooperative behaviour. This will not only allow us to confront the different evolutionary scenarios in which (...) cooperation may have emerged, but will especially provide the reader with a first orientation in the abundant literature on human cooperation.

Human faces are among the most important visual stimuli that we encounter at all ages. This importance partly stems from the face as a conveyer of information on the emotional state of other individuals. Previous research has demonstrated specific scanning patterns in response to threat-related compared to non-threat-related emotional expressions. This study investigated how visual scanning patterns toward faces which display different emotional expressions develop during infancy. The visual scanning patterns of 4-month-old and 7-month-old infants and adults when (...) looking at threat-related (i.e., angry and fearful) versus non-threat-related (i.e., happy, sad, and neutral) emotional faces were examined. We found that infants as well as adults displayed an avoidant looking pattern in response to threat-related emotional expressions with reduced dwell times and relatively less fixations to the inner features of the face. In addition, adults showed a pattern of eye contact avoidance when looking at threat-related emotional expressions that was not yet present in infants. Thus, whereas a general avoidant reaction to threat-related facial expressions appears to be present from very early in life, the avoidance of eye contact might be a learned response toward others' anger and fear that emerges later during development.

A dynamic systems (DS) approach uncovers important connections between emotion and neurophysiology. It is critical, however, to include a developmental perspective. Strides in the understanding of emotional development, as well as the present use of DS in developmental science, add significantly to the study of emotion. Examples include stranger fear during infancy, intermodal perception of emotion, and development of individual emotional systems.
