The quality of sucking in infants with colic

Feeding problems have been reported in infants with colic. The purpose of this study was to examine the nutritive sucking pattern of infants identified as having colic. Twenty-nine infants (16 with colic and 13 controls) between the ages of 1 to 3 months, being bottle-fed by their mothers, were observed by a blind examiner. We hypothesized that infants with colic would show greater disorganization in nutritive sucking and show greater variability in sucking rate than infants without colic, as assessed by the revised Neonatal Oral Motor Assessment Scale (NOMAS). Infants with colic were found to present a disorganized sucking pattern; namely, a lack of rhythmical movement and a difference in amount of sucks per burst than infants without colic. Methods of intervention are suggested.     

Children's reasoning about responses to peer aggression: Victim's and witness's expected and prescribed behaviors

This research examined children's reasoning about expected (i.e., what a peer would do) and prescribed (i.e., what a peer should do) responses to unprovoked, intentional aggressive actions in two contexts: as a victim of such a transgression and as a witness to the incident. Physical harm and property damage items were used in a structured interview format. There were 90 subjects drawn from three elementary school grades (2nd, 4th, and 6th). Children differentiated between the expected and prescribed responses of peers and significant developmental differences in children's evaluations were found. Although the majority of the subjects in all grades denounced retaliation on the basis of concerns about others' welfare, older children stated that peers were likely to retaliate against the perpetrator nonetheless. Across different contexts, older children's responses appeared to reveal a greater independence from authority in negotiating peer interactions. In evaluating the witness's responses to aggressive acts, younger children's expected and prescribed responses were less disparate than that of the older children. The utility of including different vantage points of the child in examining children's social reasoning about aggression and the application of the present findings to social information-processing models are discussed. © 1996 Wiley-Liss, Inc.

Playing the Woman Card: Ambivalent Sexism in the 2016 U.S. Presidential Race

Late in the 2016 U.S. Presidential primary, Donald Trump attacked Hillary Clinton for playing the “woman’s card.” Theories of system justification suggest that attitudes about gender, particularly endorsement of hostile and benevolent sexism, likely shaped reactions to this campaign attack. Using a set of two studies, we find that hostile sexists exposed to the attack showed increased support for Trump and decreased support for Clinton. Benevolent sexists, however, reacted to Trump’s statements with increased support for Clinton, consistent with benevolent sexism’s focus on protecting women (Study 1). We further found that the woman card attack produced distinct emotional reactions among those with low and high levels of hostile and benevolent sexism. The attack also increased political participation among hostile sexists (Study 2). Our results offer new insights into the role of sexism in the 2016 presidential contest and further the discipline’s understanding of the gendered dimension of negative campaigning.     

Medical knowledge in a social world: Introduction to the special issue

Philosophy of medicine has traditionally examined two issues: the scientific ontology for medicine and the epistemic significance of the types of evidence used in medical research. In answering each question, philosophers have typically brought to bear tools from traditional analytic philosophy. In contrast, this volume explores medical knowledge from the perspective offered by social epistemology. While many of the same issues are addressed, the approach to these issues generates both fresh questions and new insights into old debates. In addition, the broader purview offered by social epistemology opens up opportunities to address new topics such as the role of consensus conferences, epistemic injustice, the value of medical knowledge, continuing medical education, and industry funding. This article situates and summarizes the contributions to this special issue.

     

Eliciting information and cues to deceit through sketching in interpreter‐based interviews

As interviewees typically say less when an interpreter is present, we examined whether this was caused by interpreters not interpreting everything interviewees says or by interviewees providing less information. We further examined (a) the effect of a model drawing on providing information and (b) the diagnostic value of total details and the proportion of complications as cues to deceit. Hispanic, Russian, and South Korean participants were interviewed by native interviewers or by a British interviewer through an interpreter. Truth tellers discussed a trip they had made; liars fabricated a story. Participants received no instruction (condition 1) or were instructed to sketch while narrating without (condition 2) or with (condition 3) being given examples of detailed sketches. Interviewees said less when an interpreter was present because they provided less information. Truth tellers gave more details and, particularly, obtained a higher proportion of complications than liars. The sketching manipulation had no effect.     

Using Automated Learning Devices for Monkeys (ALDM) to study social networks

Social network analysis has become a prominent tool to study animal social life, and there is an increasing need to develop new systems to collect social information automatically, systematically, and reliably. Here we explore the use of a freely accessible Automated Learning Device for Monkeys (ALDM) to collect such social information on a group of 22 captive baboons (Papio papio). We compared the social network obtained from the co-presence of the baboons in ten ALDM testing booths to the social network obtained through standard behavioral observation techniques. The results show that the co-presence network accurately reflects the social organization of the group, and also indicate under which conditions the co-presence network is most informative. In particular, the best correlation between the two networks was obtained with a minimum of 40 days of computer records and for individuals with at least 500 records per day. We also show through random permutation tests that the observed correlations go beyond what would be observed by simple synchronous activity, to reflect a preferential choice of closely located testing booths. The use of automatized cognitive testing therefore presents a new way of obtaining a large and regular amount of social information that is necessary to develop social network analysis. It also opens the possibility of studying dynamic changes in network structure with time and in relation to the cognitive performance of individuals.     

Effects of emotional valence and arousal manipulation on eyeblink classical conditioning and autonomic measures

Using a classical eyeblink conditioning paradigm, we have previously shown that the rate of acquisition of a conditioned response may be manipulated by engaging subjects in background tasks of varying complexity concurrent to conditioning. To further examine the influence of the background environment on conditioning, a picture set designed to elicit emotional responses, the International Affective Picture System (IAPS), was presented to subjects during classical eyeblink conditioning. The results suggest that eyeblink conditioning does appear to be sensitive to contextual manipulations of arousal. Pictures rated as very arousing were found to engage subjects enough to enhance learning, although not to the point that autonomic functions were significantly altered between picture groups. We suggest that group differences in learning may be a result of either novelty of, or vigilance to, interesting pictures rather than as a direct result of physiological arousal.     

Self‐esteem,perception of relationships,and emotional distress: A cross‐cultural study

This study examined the relative importance of self‐esteem, family cohesion, and support from friends in predicting depressed mood and anxiety in Japanese and American college students. Contrary to expectations, self‐esteem was the strongest predictor of emotional distress in both groups of students. Nevertheless, consistent with predictions derived from Markus and Kitayama's theory of self‐construals, family cohesion accounted for a significantly larger percentage of the variance in predicting emotional distress in Japan than in the United States. In both countries, the relations between support from friends and the measures of emotional distress were entirely mediated by self‐esteem. However, among Japanese students, family cohesion accounted for additional significant variance in predicting the measures of emotional distress, even after controlling for self‐esteem.     

Generalized relational matching by guinea baboons (Papio papio) in two-by-two-item analogy problems

Analogical reasoning is considered the hallmark of human reasoning, but some studies have demonstrated that language- and symbol-trained chimpanzees can also reason analogically. Despite the potential adaptive value of this ability, evidence from other studies strongly suggests that other nonhuman primates do not have this capacity for analogical reasoning. In our three experiments, 6 of 29 baboons acquired the ability to perform a relational matching-to-sample (RMTS) task in which pairs of shapes composed relational displays. Five of these 6 monkeys then transferred this ability to RMTS tasks using novel exemplars of identity (elements in a pair are the same) and nonidentity (elements in a pair are different) relations. This transfer occurred even on trials in which the incorrect pair shared an element with the sample pair with which it was being compared. The baboons retained this ability 12 months later. The findings from our study of symbol-naive monkeys indicate that although language and symbol training facilitate conceptual thinking in nonhuman primates, such training is not a prerequisite for analogical reasoning.
