ICAP is a theory of active learning that differentiates students’ engagement based on their behaviors. ICAP postulates that Interactive engagement, demonstrated by co‐generative collaborative behaviors, is superior for learning to Constructive engagement, indicated by generative behaviors. Both kinds of engagement exceed the benefits of Active or Passive engagement, marked by manipulative and attentive behaviors, respectively. This paper discusses a 5‐year project that attempted to translate ICAP into a theory of instruction using five successive measures: (a) teachers’ understanding of ICAP after (...) completing an online module, (b) their success at designing lesson plans using different ICAP modes, (c) fidelity of teachers’ classroom implementation, (d) modes of students’ enacted behaviors, and (e) students’ learning outcomes. Although teachers had minimal success in designing Constructive and Interactive activities, students nevertheless learned significantly more in the context of Constructive than Active activities. We discuss reasons for teachers’ overall difficulty in designing and eliciting Interactive engagement. (shrink)

Humanoid robots used for sexual purposes are beginning to look increasingly lifelike. It is possible for a user to have a bespoke sexbot created which matches their exact requirements in skin pigmentation, hair and eye colour, body shape, and genital design. This means that it is possible—and increasingly easy—for a sexbot to be created which bears a very high degree of resemblance to a particular person. There is a small but steadily increasing literature exploring some of the ethical issues surrounding (...) sexbots, however sexbots made to look like particular people is something which, as yet, has not been philosophically addressed in the literature. In this essay I argue that creating a lifelike sexbot to represent and resemble someone is an act of sexual objectification which morally requires consent, and that doing so without the person’s consent is intrinsically wrong. I consider two sexbot creators: Roy and Fred. Roy creates a sexbot of Katie with her consent, and Fred creates a sexbot of Jane without her consent. I draw on the work of Alan Goldman, Rae Langton, and Martha Nussbaum in particular to demonstrate that creating a sexbot of a particular person requires consent if it is to be intrinsically permissible.

Recent definitions have focused on the objective the important uses of sonification in terms of scientific method.

A central feature of complexity is that it is based on non-linear, recursive relations. However, in most current accounts of complexity such relations, while non-linear, are based on the reductive relations of a Newtonian onto-epistemological framework. This means that the systems that are emergent from the workings of such relations are a narrowly reduced spectrum of complex systems. It is argued that John Dewey’s trans-actional relations, relations that are characterized by an irreducible internal distinction, can function as an exemplar of (...) the less reductive relations seen in living complex systems. Conceptualizing complex relations and complex systems in a less reductive way allows indeterminate concepts such as epistemological limits and the generative production of meaning, which are inextricably linked, to be considered. Methodologically, such lessened reduction highlights functional systems, revealing aspects of the biopsychosocial human ‘complex system of complex systems’ that are hidden from view in a Newtonian framework.

The motto of the Royal Society—Nullius in verba—was intended to highlight the members’ rejection of received knowledge and the new place they afforded direct empirical evidence in their quest for genuine, useful knowledge about the world. But while many studies have raised questions about the construction, reception and authentication of knowledge, Evidence in the Age of the New Sciences is the first to examine the problem of evidence at this pivotal moment in European intellectual history. What constituted evidence—and for whom? (...) Where might it be found? How should it be collected and organized? What is the relationship between evidence and proof? These are crucial questions, for what constitutes evidence determines how people interrogate the world and the kind of arguments they make about it. In this important new collection, Lancaster and Raiswell have assembled twelve studies that capture aspects of the debate over evidence in a variety of intellectual contexts. From law and theology to geography, medicine and experimental philosophy, the chapters highlight the great diversity of approaches to evidence-gathering that existed side by side in the sixteenth and seventeenth centuries. In this way, the volume makes an important addition to the literature on early science and knowledge formation, and will be of particular interest to scholars and advanced students in these fields.

This article advances the theoretical and practical value of workplace spirituality by drawing on person–organization (PO) fit theory and transpersonal psychology to investigate three questions: (a) What antecedents lead individuals and organizations to seek and foster workplace spirituality? (b) What are the perceived spiritual needs of individuals, and how are those needs fulfilled in the workplace? and (c) What are the consequences of meeting spiritual needs as individuals perceive them? Using constructivist grounded theory, analysis of interview data from thirty-four participants (...) located in organizations across the Netherlands, Ireland, the United Kingdom, and Portugal led to development of a workplace spirituality, PO fit model in which we propose reconciling self as a core factor of workplace spirituality. We note how through the process of reconciling self, workplace spirituality is related to meaning making and how an individual perceives their work environment as conducive to self-expression and inner purpose. Practical and theoretical implications are discussed, as are limitations of the study and ideas for future research. (shrink)

The Evil‐god challenge attempts to undermine classical monotheism by arguing that because the existence of an evil god is similar in reasonableness to the existence of a good god, the onus is on the theist to justify their belief in the latter over the former. In the Part I paper, I defined the Evil‐god challenge, distinguished between several types of Evil‐god challenge, and presented its history and recent developments. In this paper, I describe the merits of the challenge, outline and (...) address the main objections that have been posed to it, and discuss some of the implications for classical monotheism if the Evil‐god challenge remains untarnished by objections.

The Evil‐god challenge has enjoyed a flurry of attention after its resurrection in Stephen Law's, 2010 paper of the same name. Intended to undermine classical monotheism, the Evil‐god challenge rests on the claim that the existence of all‐powerful, all‐knowing, all‐evil god (Evil‐god) is roughly as likely as the existence of an all‐powerful, all‐knowing, all‐good god (Good‐god). The onus is then placed on those who believe in Good‐god to explain why their belief should be considered significantly more reasonable than belief in (...) Evil‐god. In this paper, I provide a comprehensive exposition of the Evil‐god challenge by exploring its history and recent developments. The forthcoming part II paper will present and address the main objections that have been posed to the Evil‐god challenge and consider its implications for classical monotheism. (shrink)

This article focuses on soils as more-than-human subjects who are both living entities and ‘lenses’ through which we may begin to rethink some of the conventional parameters of ecology, communication and even the grounding of some western philosophical traditions on which these boundaries have stood. Just as the very term ‘more-than-human’ potentially exceeds the relegation of both soilogic agents and animalities to subservient status, likewise this discussion embarks from a more-than-humanist (‘posthumanist’) position. As we attempt to interact with living systems (...) and ways of being in broader, more expansive terms, it becomes possible to catch conceptual glimpses of less hierarchical ontologies as they are understood by some more-than-western cultures. I have also drawn inspiration from artistic, theoretical and political movements in the west that have sought to interrupt the primacy of Eurocentric humanism in institutions and philosophical arenas. This presages dirty thinking. (shrink)

The son of a shopkeeper, Joseph Lancaster received little formal education himself. In 1798 he set up a school in Southwark, waiving fees for poor children. Originally published in 1803, this work sets out in detail the philosophy and practice of Lancaster's system of education, which relied on peer tutoring. He was always concerned with the education of the underprivileged in industrial cities, lamenting that 'poor children be deprived of even an initiatory share of education, and of almost (...) any attention to their morals'. The early decades of the nineteenth century saw the peak of the popularity of Lancaster's system as his ideas spread and inspired the establishment of schools around the world. His book is still significant in the history of educational methods. This reissue of the revised third edition of 1805 incorporates a brief 1840 biography of Lancaster. (shrink)

It is often thought that religious experiences provide support for the cumulative case for the existence of the God of classical monotheism. In this paper, I formulate an Evil-god challenge that invites classical monotheists to explain why, based on evidence from religious experience, the belief in an omnipotent, omniscient, omnibenevolent god is significantly more reasonable than the belief in an omnipotent, omniscient, evil god. I demonstrate that religious experiences substantiate the existence of Evil-god more so than they do the existence (...) of Good-god, and, consequently, that the traditional argument from religious experience fails: it should not be included in the cumulative case for the existence of Good-god.

An elderly patient in a care home only wants human nurses to provide her care – not robots. If she selected her carers based on skin colour, it would be seen as racist and morally objectionable, but is choosing a human nurse instead of a robot also morally objectionable and speciesist? A plausible response is that it is not, because humans provide a better standard of care than robots do, making such a choice justifiable. In this paper, I show why (...) this response is incorrect, because robots can theoretically care as well as human nurses can. I differentiate between practical caring and emotional caring, and I argue that robots can match the standard of practical care given by human nurses, and they can simulate emotional care. There is growing evidence that people respond positively to robotic creatures and carebots, and AI software is apt to emotionally support patients in spite of the machine’s own lack of emotions. I make the case that the appearance of emotional care is sufficient, and need not be linked to emotional states within the robot. After all, human nurses undoubtedly ‘fake’ emotional care and compassion sometimes, yet their patients still feel adequately cared for. I show that it is a mistake to claim that ‘the human touch’ is in itself a contributor to a higher standard of care; ‘the robotic touch’ will suffice. Nevertheless, it is not speciesist to favour human nurses over carebots, because carebots do not suffer as the result of such a choice. (shrink)

Based on interviews and field research, the authors explore the sets of ideas Arab tribespeople from Ras Al-Khaimah had about tribe and community; social and economic networks, and jural contracts for livelihoods and profits; their uses of their environments; the moral relations of credit, debt and labour; ruling; economic and political transformations; and ideas of regional history where conflicts were regarded as disputes over sets of ideas, and informal accounts of tribal and local histories.Their lively descriptions and explanations of life (...) before oil portrayed tribal societies whose relationships were moral rather than political and were between jurally equal persons. All lived from their own resources; 'wealth' was material self-sufficiency; 'riches' the richness of social relationships. Political arenas were decentralised and underpinned by common cultural and moral values.Published sources give a wider context to these ideas and events which show the great complexity and differing perspectives of 'life before oil' in the Gulf.

In this article, I argue that Sartre's biography of Jean Genet, Saint Genet Actor and Martyr, can serve as an instrument of liberation for pariahs living today. Like Sartre, I define the word "pariah" to mean people who have suffered trauma in their lives and who are internally and socially oppressed as a consequence. Saint Genet's power to free us arises paradoxically out of the conservative aspects for which it has been criticized in the last few years. I am referring (...) especially to reproaches that Sartre makes things up about Genet's childhood just to suit his theories. In this paper, I also broaden the use of the term "pariah" to include some people who have only recently begun receiving respectful recognition such as survivors of domestic violence and child abuse, as well as female sufferers of depression. My views are inspired by research done in Sartre and Genet studies and also, by information provided so generously by fellow-pariahs and supporters in the medical field. (shrink)

This paper examines the coherence of naturalistic personal pantheism in an attempt to reconcile pantheism, naturalism, and a personal concept of God. NPP proposes that i) God is identical with the universe, ii) the universe is entirely natural, and iii) God is personal. Several critics of accounts of a God such as this have voiced concerns about a natural — as opposed to a supernatural — God, since a natural God cannot be worship-worthy. In response, I propose a controversial premise (...) — physical primacy — to justify the worship-worthiness of a natural God. Physical primacy maintains that physical existence is a great-making property, therefore a God that exists naturally is greater than a God that exists supernaturally. I maintain that NPP is an attractive alternative to other theisms because it bypasses the pairing problem, presents a worship-worthy concept of God, and boasts ontological simplicity. (shrink)

In his fairly recent article in this journal, ‘The Evil-god Challenge – A Response’, Keith Ward attempts to nullify Stephen Law's evil-god challenge by presenting several arguments intended to demonstrate that an omniscient, omnipotent being cannot conceivably be evil. In this article, I critically respond to each of Ward's arguments to reach the conclusion that an omnipotent, omniscient being could indeed be evil. To achieve this, I claim that neither perfect empathy nor rationality entails benevolence, that the desire for suffering (...) is not necessarily pathological, and that human desire for a good god does not entail that god is actually benevolent.Export citation.

The greatest contemporary challenge in the arena of cognitive neuroscience concerns the relation between consciousness and the brain. Over recent years the focus of work in this area has switched from the analysis of diverse spatial regions of the brain to that of the timing of neural events. It appears that two conditions are necessary in order for neural events to become correlated with conscious experience. First, the firing of assemblies of neurones must achieve a degree of coherence, and, second, (...) reflexive (i.e. top-down, or reentrant) neural pathways must be activated. It does not, of course, follow that such neural activity causes consciousness; it may be, for example, that the neural activity formats the brain to interact with consciousness. The latter possibility is suggested by analysis of mystical texts suggesting that coherence and reflexivity constitute the conditions for the influx of “spirit.” Kabbalistic sources, for example, describe a hierarchy of “brains” in the human and divine realms through which the principles of coherence and reflexivity operate. Whilst the ontological assumptions of such a scheme place it beyond the realm of psychology, parallels with the picture deriving from the contemporary cognitive neuroscience of consciousness are striking.

It is suggested that the impetus to generate models is probably the most fundamental point of connection between mysticism and psychology. In their concern with the relation between ‘unseen’ realms and the ‘seen’, mystical maps parallel cognitive models of the relation between ‘unconscious’ and ‘conscious’ processes. The map or model constitutes an explanation employing terms current within the respective canon. The case of language mysticism is examined to illustrate the premise that cognitive models may benefit from an understanding of the (...) kinds of experiences gained, and explanatory concepts advanced, within mystical traditions. Language mysticism is of particular interest on account of the central role thought to be played by language in relation to self and the individual's construction of reality. The discussion focuses on traditions of language mysticism within Judaism, in which emphasis is placed on the deconstruction of language into primary elements and the overarching significance of the divine Name. Analysis of the detailed techniques used suggests ways in which multiple associations to any given word/concept were consciously explored in an altered state. It appears that these mystics were consciously engaging with what are normally preconscious cognitive processes, whereby schematic associations to sensory images or thoughts are activated. The testimony from their writings implies that these mystics experienced distortions of the sense of self , which may suggest that, in the normal state, ‘I’ is constructed in relation to the preconscious system of associations. Moreover, an important feature of Hebrew language mysticism is its emphasis on embodiment -- specific associations were deemed to exist between the letters and each structure of the body. Implications, first, for the relationship between language and self, and, second, for the role of embodiment in relation to self are discussed. The importance of the continual emphasis on the Name of God throughout the linguistic practices may have provided a means for effectively replacing the cognitive indexing function hypothesized here to be normally played by ‘I’ with a more transpersonal cognitive index, especially in relation to memory.

This paper reports the findings of a predominantly qualitative study that explored the effects of the practice of Philosophy for Children on pupils’ affective engagement.[1] From its conception, the practice of P4C has been linked to the development of caring and collaborative thinking and the study aimed to closely consider that relationship. An appropriate self-designed P4C program was implemented with 75 Year 9 pupils of Religious Education at an independent secondary school in the United Kingdom. An interpretive research approach was (...) taken and thematic analysis was appropriated to analyse the data. Findings supported the claims of previous research that P4C can foster affective engagement in many pupils, particularly those pupils who find emotional expression and interpersonal interactions challenging. A tentative conclusion reached supposes that P4C has the potential to contribute to the affective engagement of pupils, but with the recommendation that implementing a P4C program must be executed carefully and with the mindfulness that it may not have the same potential or usefulness for all pupils universally.

SummaryThe French classical economist Jean-Baptiste Say gained fame as a political economist in the first half of the nineteenth century. In 1785, aged eighteen, he visited Britain for the first time to prepare himself for a commercial career and to learn English. Other visits followed; but, in contrast to his visits in subsequent years, during 1814/15 and 1825, little is known about his first visit and those writing about Say tend to ignore it or consider it irrelevant. By drawing on (...) his draft autobiography and on his street plan of Croydon, the article adds more information to supplement the meagre published accounts of this visit: where and with whom he lived, for whom he worked, whom he met and what his itinerary was during the time he was in England. The key places Say mentions are London, Croydon and Fulham. While not a definitive account of the visit, it does correct factual errors, clear up confusion and clarify ambiguities. The article questions speculations about Say witnessing the Industrial Revolution and proposes that, during his visit, his interests may have lain elsewhere than only in matters of commerce and taxation.

In these collaborative, theoretical and performative pieces our aim is towards radical expansions of various formal parameters in western philosophy through art praxis that de-centres the roles played by the animal subject, industrial technologies, and soil in modernist paradigms. Exceeding these conventions demands pushing against/past blockages (aporias) to broader engagement with whatever refigured subjectivities are called into constellative gathering in the process. The immanent multiplicity of constellative (Soilogic) analysis ‘cuts in all directions’ in its insistence on attempting to ‘upend’ multiple (...) disciplines simultaneously rather than remaining mere cross-disciplinary embellishment between art and philosophy. Opening new ruptures in horizons of interpretation and maintaining them through artistic and philosophical agitation involves a ‘fidelity to the impossible’ (Young), and a reach beyond the known and tried. It is also a reach towards a blurring of Techne and poeisis in the inter(fur)faces of Dawn (a dark Horse), Gladys (a Goat), and the debris field of the zeppelin USS Macon that crashed into the ocean and sank off the coast of Monterey, CA in 1935. Initially we did so by painting portraits of Nietzsche and Benjamin on Dawn, putting them into conversation with each other on the question of Animality. We then attempted to make ‘haptic’ contact with the Macon while posing performative questions about interrelations, telepathies and hauntings among Animalities, Techne and more-than-humanist Materialities.

Students are using file sharing sites to breach academic integrity in light of the Covid-19 pandemic. This paper analyses the use of one such site, Chegg, which offers “homework help” and other academic services to students. Chegg is often presented as a file sharing site in the academic literature, but that is just one of many ways in which it can be used. As this paper demonstrates, Chegg can and is used for contract cheating This is despite the apparent existence (...) of an Honour Code on Chegg which asks students not to breach academic integrity. With pandemic led safety considerations leading to increased online teaching and assessment, the paper analyses data relating to how Chegg is used by students in five STEM subjects, namely Computer Science, Mechanical Engineering, Electrical Engineering, Physics and Chemistry. The results show that students are using Chegg to request exam style questions. They demonstrate that contract cheating requests can be put live and answered within the short duration of an examination. The number of student requests posted for these five subjects increased by 196.25% comparing the time period April 2019 to August 2019 with the period April 2020 to August 2020. This increase corresponds with the time when many courses moved to be delivered and assessed online. The growing number of requests indicates that students are using Chegg for assessment and exam help frequently and in a way that is not considered permissible by universities. The paper concludes by recommending that academic institutions put interventions in place to minimise the risk to educational standards posed by sites such as Chegg, particularly since increased online teaching and assessment may continue after the pandemic.

Contract cheating services are marketing to students at discipline level, using increasingly sophisticated techniques. The discipline level reach of these services has not been widely considered in the academic integrity literature. Much of the academic understanding of contract cheating is not discipline specific, but the necessary solutions to this problem may need to vary by discipline. This paper reviews current knowledge about contract cheating services at the discipline level, including summarising four studies that rank the relative volume of contract cheating (...) within different academic disciplines. The reviewed studies show high volumes of contract cheating transactions in the disciplines of Business and Computing. Examples of discipline level contract cheating research and service advertising are provided. The main contribution of the paper is an analysis of the discipline level reach by contract cheating services as seen through an analysis of Google search results from the United Kingdom. This analysis of 19 discipline groups uses measures of organic search engine results, paid results and competition. Three discipline groups are shown as currently being heavily exploited by essay mills; these are: Architecture, Building and Planning, Computer Science and Law. In addition, the discipline group of Creative Arts and Design is shown to be at risk of future exploitation. The paper recommends that academics are made aware about continual change in the contract cheating industry including the involved marketing taking place at discipline level. The paper concludes with a call to action for academia to develop discipline specific solutions to contract cheating. (shrink)

As the contract cheating market has become more sophisticated and competition has intensified, the contract cheating industry has had to redevelop its approach to gain custom. The industry has developed new models of internal operation and providers are using more sophisticated techniques to reach potential customers. This paper discusses contract cheating industry workflows and introduces terminology to allow complexities of the industry to be more consistently discussed. Examples are provided throughout to indicate the scale and challenge of the contract cheating (...) industry operations.An analysis of contract cheating operations on the micro-outsourcing website Fiverr.com is presented, using comparative data collected in June 2016 and October 2018. The analysis of the data demonstrates how the contract cheating industry is seeing continual change. Specifically, on Fiverr.com, this includes an increase in the number of providers offering essay writing services, particularly those from Kenya and Pakistan. The increase in service availability is accompanied by an associated reduction in essay pricing. The advertised pricing per 1000 words has dropped substantially, from $31.73 USD to $5.73 USD. The accounts used by contract cheating providers are also being replaced at an increased rate.Based on the data, contract cheating providers on Fiverr.com are currently estimated to be taking a minimum of $92,001 USD per year in revenue. This is an example calculated from only one search term on which contract cheating providers advertise on only one micro-outsourcing site used for contract cheating. The actual industry income from micro-outsourcing web sites is likely to be substantially higher. (shrink)

Background: Currently, graduating nurses face pandemic-related uncertainty including gaps in risk perception, unexpected Covid-19 moral dilemmas, and distress surrounding personal health risk. Research question/aim/objectives/Method: The purpose of this basic qualitative descriptive study is to describe the willingness of graduating nurses to provide care during the Covid-19 pandemic. Participants and research context: One week prior to graduation, students were required to submit a written assignment describing willingness to practice in light of the ongoing pandemic. Ethical considerations: This study was approved by (...) an Institutional Review Board. Findings/results: Eighty-four ( n = 84) assignments were used for analysis. Of these, 82% (n = 69) of the graduating nurses describe a willingness to voluntarily care for Covid-19 patients. After summarizing narrative responses, two themes emerged including self-assessment of personal and familial risk and conflicting obligations. Discussion: The assessment of risk to self and family are key in determining whether graduating nurses will care for Covid-19 patients. Conflicting obligations may contribute to stress and uncertainty potentially leading to early burnout. Conclusion: Findings from this study can inform academicians of the need to adequality prepare graduating nurses for Covid-19-associated risks and ethical decision making. Organizations should alter residencies and orientation to support the needs of new nurses. (shrink)

Purpose Students have direct access to academic ghost writers who are able to provide for their assessment needs without the student needing to do any of the work. These ghost writers are helping to fuel the international industry of contract cheating, raising ethical dilemmas, but not much is known about the writers, their business or how they operate. This paper aims to explore how the ghost writers market their services and operate, based on observable information. Design/methodology/approach This paper reviews data (...) from providers actively offering contract cheating services available to the public on Fiverr.com, a low-cost micro outsourcing site. The search term write essay is used to identify providers, finding 103 Gigs from 96 unique providers. Visible information, such as provider marketing, advertised services, pricing information and customer reviews, is analysed. Findings The results demonstrate that bespoke essays are readily available to students at a low cost. The majority of providers operate from Kenya. Revenue calculations indicate a price point of US$31.73 per 1,000 words, below the cost of traditional essay mills, but show that these 96 providers have generated around US$270,000 of essay writing business between them. Originality/value This study affords a look into a complex and established industry whose inner workings are normally kept private and for which little published information currently exists. The research adds to what is known about the extent, location and operation of the contract cheating industry. (shrink)

Organoids are quickly becoming an accepted model for understanding human biology and disease. Pluripotent stem cells (PSC) provide a starting point for many organs and enable modeling of the embryonic development and maturation of such organs. The foundation of PSC‐derived organoids can be found in elegant developmental studies demonstrating the remarkable ability of immature cells to undergo histogenesis even when taken out of the embryo context. PSC‐organoids are an evolution of earlier methods such as embryoid bodies, taken to a new (...) level with finer control and in some cases going beyond tissue histogenesis to organ‐like morphogenesis. But many of the discoveries that led to organoids were not necessarily planned, but rather the result of inquisitive minds with freedom to explore. Protecting such curiosity‐led research through flexible funding will be important going forward if we are to see further ground‐breaking discoveries. (shrink)

Our objective is to test an optimality model of human fertility that specifies the behavioral requirements for fitness maximization in order (a) to determine whether current behavior does maximize fitness and, if not, (b) to use the specific nature of the behavioral deviations from fitness maximization towards the development of models of evolved proximate mechanisms that may have maximized fitness in the past but lead to deviations under present conditions. To test the model we use data from a representative sample (...) of 7,107 men living in Albuquerque, New Mexico, between 1990 and 1993. The model we test proposes that low fertility in modern settings maximizes number of grandchildren as a result of a trade-off between parental fertility and next generation fertility. Results do not show the optimization, although the data do reveal a trade-off between parental fertility and offspring education and income.We propose that two characteristics of modern economies have led to a period of sustained fertility reduction and to a corresponding lack of association between income and fertility. The first is the direct link between costs of investment and wage rates due to the forces of supply and demand for labor in competitive economies. The second is the increasing emphasis on cumulative knowledge, skills, and technologies in the production of resources. Together they produce historically novel conditions. These two features of modern economies may interact with evolved psychological and physiological mechanisms governing fertility and parental investment to produce behavior that maximizes the economic productivity of lineages at the expense of fitness. If cognitive processes evolved to track diminishing returns to parental investment and if physiological processes evolved to regulate fertility in response to nutritional state and patterns of breast feeding, we might expect non-adaptive responses when returns from parental investment do not diminish until extremely high levels are reached. With high economic payoffs from parental investment, people have begun to exercise cognitive regulation of fertility through contraception and family planning practices. Those cognitive processes maynot have evolved to handle fitness trade-offs between fertility and parental investment. (shrink)
