Awareness is a personal experience, which is only accessible to the rest of world through interpretation. We set out to identify a neural correlate of visual awareness, using brief subliminal and supraliminal verbal stimuli while measuring cerebral blood flow distribution with H215O PET. Awareness of visual verbal stimuli differentially activated medial parietal association cortex (precuneus), which is a polymodal sensory cortex, and dorsolateral prefrontal cortex, which is thought to be primarily executive. Our results suggest participation of (...) these higher order perceptual and executive cortical structures in visual verbal awareness. (shrink)

We propose that human self-domestication favored the emergence of a less aggressive phenotype in our species, more precisely phenotype prone to replace (reactive) physical aggression with verbal aggression. In turn, the (gradual) transition to verbal aggression and to more sophisticated forms of verbal behavior favored self-domestication, with the two processes engaged in a reinforcing feedback loop, considering that verbal behavior entails not only less violence and better survival, but also more opportunities to interact longer and (...) socialize with more conspecifics, ultimately enabling the emergence of more complex forms of language. Whereas in the case of self-domestication sexual selection has been proposed to work against physical aggression traits, in the case of verbal insult the selection has been proposed to work in favor of verbal aggression. The tension between these two seemingly opposing forces gets resolved/alleviated by a tendency to replace physical aggression with verbal aggression, and with verbal behavior more generally. This also helps solve the paradox of the Self Domestication Hypothesis regarding aggression, more precisely why aggression in humans has been reduced only when it comes to reactive aggression, but not when it comes to proactive aggression, the latter exhibiting an increase with the advent of modern language. We postulate that this feedback loop was particularly important during the time period before 50 kya, arguably between 200 kya and 50 kya, when humans were not fully modern, neither in terms of their skull/brain morphology and their behavior/culture, nor in terms of their self-domestication. The novelty of our approach lies (i) in giving an active role to early forms of language in interacting with self-domestication processes; (ii) in providing specific linguistic details and functions of this early stage of grammar (including insult and humor); (iii) in supplying neurobiological, ontogenetic, and clinical evidence of a link between (reactive) aggression and (reactive) verbal behavior; (iv) in identifying a variety of proxies of the earlier stages in evolution among cognitive disorders; and (v) in identifying specific points of contact and mutual reinforcement between these two processes (self-domestication and early language evolution), including reduction in physical aggression and stress/tension, as well as sexual selection.

While in our culture it is a common experience that hurting others is done more frequently by means of words than by physical force, the phenomena of verbal aggression and verbal discrimination have largely been neglected in the psychology of aggression. Connecting the research fields of aggression, discrimination, and discourse, and discussing the common definition of aggression as intentional harmdoing, it is argued that verbal discrimination, i.e., the verbal treatment of others as members of an allegedly (...) inferior group or category, must be considered a case of aggression as this practice is a violation of other persons’ rights or dignity.

Medical and public health professionals recommend wearing face masks to combat the spread of the coronavirus disease of 2019. While the majority of people in the United States support wearing face masks as an effective tool to combat COVID-19, a smaller percentage declared the recommendation by public health agencies as a government imposition and an infringement on personal liberty. Social media play a significant role in amplifying public health issues, whereby a minority against the imposition can speak loudly, perhaps using (...) tactics of verbal aggression taking the form of toxic language. We investigated the role that toxicity plays in the online discourse around wearing face masks. Overall, we found tweets including anti-mask hashtags were significantly more likely to use toxic language, while tweets with pro-mask hashtags were somewhat less toxic with the exception of #WearADamnMask. We conclude that the tensions between these two positions raise doubt and uncertainty around the issue, which make it difficult for health communicators to break through the clutter in order to combat the infodemic. Public health agencies and other governmental institutions should monitor toxicity trends on social media in order to better ascertain prevailing sentiment toward their recommendations and then apply these data-driven insights to refine and adapt their risk communication messaging toward mask wearing, vaccine uptake, and other interventions.

China has a longstanding tradition of stressing the values of harmony and coherence, and Chinese society has often been portrayed as a culture in which conflict avoidance is viewed more positively than direct confrontation and argumentation. In order to evaluate the validity of this claim, this paper sketches Chinese people’s feelings and understandings about interpersonal arguing by reporting results of a data collection in China, using measures of argumentativeness, verbal aggressiveness, argument frames, and personalization of conflict. These results were (...) compared to those from a US sample. Chinese and US data differed in complex ways, but did not show Chinese respondents to be more avoidant. The Chinese correlations among variables were a reasonable match to expectations based on Western argumentation theories, although they did not replicate the US results precisely. The paper offers evidence that Chinese respondents had a more sophisticated understanding of interpersonal arguing than their US counterparts, and were more sensitive to the constructive possibilities of face-to-face disagreement.

Trolling—the online exploitation of website, chat, or game mechanics at another user's expense—can and does take place all over cyberspace. It can take myriad forms, as well—some verbal, like trash-talking an opponent in a game, and some silent, like refusing to include a new player in a team effort during an in-game quest. However, despite this variety, there are few to no studies comparing the effects of these differing trolling types on victims. In addition, no study has yet taken (...) into account users' offline cultural context and norms into the trolling victim experience. To fill this gap in the literature, the present study put participants from three culturally-distinct countries—Pakistan, Taiwan, and the Netherlands—in a simulated trolling interaction using the Cyberball game. Participants were either flamed or ostracized by a member of their own cultural group or a minority member, and the participants' emotional responses, behavioral intentions toward the other players, and messages sent during the game were taken as indicators of their response to the trolling. Results showed that our Taiwanese sample used the most reactive aggression when trolled and our Dutch sample was the most passive. In addition, ostracism generally produced the desire to repair relationships, irrespective of cultural context, and perpetrator culture only produced an effect in the behavioral intentions of our Pakistani sample. Overall, it would appear that online and offline culture interact to produce the variety of responses to trolling seen in extant literature. Additional implications for future research into computer-mediated communication and online aggression are also discussed. (shrink)

Some people report that they argue for play. We question whether and how often such arguments are mutually entertaining for both participants. Play is a frame for arguing, and the framing may not always be successful in laminating the eristic nature of interpersonal argumentation. Previous research and theory suggest that playfulness may be associated with aggression. Respondents supplied self - report data on their arguing behaviors and orientations. We found support for the hypothesis that self - reported playfulness and aggression (...) are directly associated. We found less evidence for our hypothesized inverse association between self - reported playfulness and indices of cooperation and avoidance. Self - reports of playfulness are not significantly associated with expert coders ’ ratings of either playfulness or aggressiveness. The claim that an argument is playful should be met with skepticism, although playful arguments are possible. (shrink)

In order to reduce school attendance problems and aggressive behavior, it is essential to determine the relationship between both variables. The aim of this study was twofold: to examine the mean differences in scores on aggression, based on school refusal behavior, and to analyze the predictive capacity of high scores on aggression, based on school refusal behavior factors. The sample consisted of 1455 Spanish secondary school students, aged 13–17. The School Refusal Assessment Scale-Revised and the Aggression Questionnaire were used. (...) Results indicated that students having high levels of Physical Aggression, Verbal Aggression, Anger, and Hostility received significantly higher scores on school refusal behavior. In most cases, school refusal behavior was found to be a positive and statistically significant predictor of aggression. Students that base their school refusal on the pursuit of tangible reinforcements outside of school earned higher scores, and other functional conditions underlying school refusal behavior were found to be associated with aggression issues. The role of aggression as a risk factor for school refusal behavior is discussed. (shrink)

Aggression and Its Causes explores the causes and control of aggression from a broad scientific perspective, offering many recent findings on aggression and integrating several perspectives often viewed as incompatible. Its balanced approach combines biological, environmental, and social components to illustrate how these bases contribute to the problems of aggression. The biological section describes the possible contributions of genetic mechanisms, gender, and sexual hormones, including investigations of the premenstrual syndrome. There is also a discussion of the roles that brain mechanisms (...) may play in aggressive behavior, as well as the problems with human brain dysfunction and drug use. The environmental section describes stimuli and environmental conditions that may produce aggression, and the effects of conditioning and learning. Finally, social psychological factors are described, along with the media's effect on aggression. The author covers various applied areas of special contemporary concern, such as juvenile delinquency, sexual and physical abuse of children, spousal abuse, and rape, concluding with a final chapter that discusses various psychiatric disorders that may involve aggression. Appropriate for upper-level undergraduates in psychology, sociology, social work, criminal justice, and education, and for professionals who encounter aggression, this text offers an excellent basis for understanding the causes of aggression and many ideas for how it may be controlled.

Pickering & Garrod's interactive alignment account corresponds directly with the account Skinner gave in his book Verbal Behavior. This correspondence becomes evident when “properties of verbal stimuli” substitutes for “channels of alignment.” Skinner 's account appears to have the dual advantages of requiring fewer basic terms and integrating the field of verbal behavior with the whole field of human behavior.

Fluctuating asymmetry (FA) is small deviations from perfect symmetry in normally bilaterally symmetrical traits. We examined the relationship between FA of five body traits (ear height, length of three digits, and ankle circumference) and self-reported scores of physical and verbal aggression in a sample of 90 boys aged 10 to 15 years. The relationships between FA and scores of aggression (particularly physical aggression) were found to be negative; in other words, the most symmetrical boys showed highest aggression. One trait (...) (ankle circumference) showed the characteristics of “ideal” FA—parametric mean of zero and a normal distribution. Mean asymmetries calculated from six repeated measures of ankle FA in 30 subjects taken over a period of five months showed strong negative associations with scores of physical aggression which were independent of age, height, and weight.It is argued that soft tissue “cyclical” FA (as opposed to “fixed” bony FA) is dependent on the secretion of hormones: for example, cortisol. Causal associations between behavioral traits such as aggresion and hormones will lead to similar correlations between FA and behavior. (shrink)

The four-factor structure and psychometric properties of the Polish students adaptation of the Buss and Perry Aggression Questionnaire were investigated. The exploratory factor analyses of the responses of 604 Polish participants generally supported the four-factor model. The factors included Physical Aggression, Verbal Aggression, Anger and Hostility. The correlations between subscales, internal consistency and stability over time were evaluated and proved to be satisfactory. Apart from gender differences, 48 prison inmates and 48 students were interviewed to determine the validity of (...) the Aggression Questionnaire by testing for hypothesized differences between groups. Aggression Questionnaire showed cross-cultural differences in aggression between various nations. (shrink)

The quality of the animal-human relationship and, consequently, the welfare of animals can be improved by gentle interactions such as stroking and talking. The perception of different stimuli during these interactions likely plays a key role in their emotional experience, but studies are scarce. During experiments, the standardization of verbal stimuli could be increased by using a recording. However, the use of a playback might influence the perception differently than ‘live’ talking, which is closer to on-farm practice. (...) Thus, we compared heifers’ (n = 28) reactions to stroking while an experimenter was talking soothingly (‘live’) or while a recording of the experimenter talking soothingly was played (‘playback’). Each animal was tested three times per condition and each trial comprised three phases: pre-stimulus, stimulus (stroking and talking) and post-stimulus. In both conditions, similar phrases with positive content were spoken calmly, using long low-pitched vowels. All tests were video recorded and analyzed for behaviors associated with different affective states. Effects on the heifers’ cardiac parameters were assessed using analysis of heart rate variability. Independently of the auditory stimuli, longer durations of neck stretching occurred during stroking, supporting our hypothesis of a positive perception of stroking. Observation of ear positions revealed longer durations of the back up position and less ear flicking and changes of ear positions during stroking. The predicted decrease in HR during stroking was not confirmed; instead we found a slightly increased mean HR during stroking with a subsequent decrease in HR, which was stronger after stroking with live talking. In combination with differences in HRV parameters, our findings suggest that live talking might have been more pleasurable to the animals and had a stronger relaxing effect than ‘playback’. The results regarding the effects of the degree of standardization of the stimulus on the variability of the data were inconclusive. We thus conclude that the use of recorded auditory stimuli to promote positive affective states during human-animal interactions in experimental settings is possible, but not necessarily preferable.

The paediatric intensive care unit (PICU) is a high-stress environment for parents, families and health care professionals (HCPs) alike. Family members experiencing stress or grief related to the admission of their sick child may at times exhibit challenging behaviours; these exist on a continuum from those that are anticipated in context, through to unacceptable aggression. Rare, extreme behaviours include threats, verbal or even physical abuse. Both extreme and recurrent ‘subthreshold’ behaviours can cause significant staff distress, impede optimal clinical care (...) and compromise patient outcomes. The unique PICU environment and model of care may magnify stressors for both families and staff and the family-centred approach to care (FCC) central to paediatric practice, may also contribute to contextual challenges. Pervasive conflict in paediatric healthcare is harmful for patients, families, PICU staff and the institution more broadly. We propose that caring for children and caring for staff are inseparable goals and the latter has been inadvertently but detrimentally deprioritised as FCC has become a primary focus. A transparent and graded hierarchy of responses to variable levels of challenging behaviour is necessary to ensure that families are supported, while HCPs remain protected in the workplace. This requires establishing firm limits supported by all teams and levels of the institution. As such, we aim to identify and clarify the context and impact of challenging parent and family behaviour in the PICU and to offer potential, proactive mitigation strategies, based on reflections and stakeholder discussion following recent clinical challenges and experiences in our unit.

Purpose: The main aim of the research was to analyse aggression dimensions among athletes practising martial arts and combat sports.Material and Methods: There were 219 respondents. The Buss and Perry Aggression Questionnaire in the Polish adaptation by Siekierka was applied.Results: Martial arts apprentices turned out to present a statistically significantly lower level of hostility and of the general aggression index than combat sports athletes. It turned out that lower level of aggression was noted in female participants, verbal aggression, hostility, (...) and the general aggression index. Analysis revealed that the training experience and the training rank did not differentiated the level of the respondents' particular aggression dimensions.Conclusions: It would be advisable to perform parallel analyses in other areas of Poland and take into account the respondents' education and place of residence.

ABSTRACTAdults perceive emotional expressions categorically, with discrimination being faster and more accurate between expressions from different emotion categories than between two stimuli from the same category. The current study sought to test whether facial expressions of happiness and fear are perceived categorically by pre-verbal infants, using a new stimulus set that was shown to yield categorical perception in adult observers. These stimuli were then used with 7-month-old infants using a habituation and visual preference paradigm. Infants were first (...) habituated to an expression of one emotion, then presented with the same expression paired with a novel expression either from the same emotion category or from a different emotion category. After habituation to fear, infants displayed a novelty preference for pairs of between-category expressions, but n... (shrink)
