A Necessary Neologism: The Origin and Uses of Suicide

In English-speaking societies today the word suicide is the preferred term for self-inflicted death. But it has not always been so. Evidence recounted here suggests that suicide was devised by Sir Thomas Browne and first published in his book Religio Medici in 1643. Although little used at first, suicide had become established as noun and verb by the mid-18th century and was recognized by inclusion in Johnson's Dictionary. The modern world has seen an enormous increase in words and expressions derived from suicide, some of which are discussed here.     

Ordered short-term memory differs in signers and speakers: implications for models of short-term memory

Capacity limits in linguistic short-term memory (STM) are typically measured with forward span tasks in which participants are asked to recall lists of words in the order presented. Using such tasks, native signers of American Sign Language (ASL) exhibit smaller spans than native speakers ([Boutla, M., Supalla, T., Newport, E. L., & Bavelier, D. (2004). Short-term memory span: Insights from sign language. Nature Neuroscience, 7(9), 997-1002]). Here, we test the hypothesis that this population difference reflects differences in the way speakers and signers maintain temporal order information in short-term memory. We show that native signers differ from speakers on measures of short-term memory that require maintenance of temporal order of the tested materials, but not on those in which temporal order is not required. In addition, we show that, in a recall task with free order, bilingual subjects are more likely to recall in temporal order when using English than ASL. We conclude that speakers and signers do share common short-term memory processes. However, whereas short-term memory for spoken English is predominantly organized in terms of temporal order, we argue that this dimension does not play as great a role in signers' short-term memory. Other factors that may affect STM processes in signers are discussed.     

The influence of recent experience on perceptions of attractiveness

Adults rate average faces as more attractive than most of the faces used in the creation of the average. One explanation for this is that average faces appear as both more familiar and more attractive because they resemble internal face prototypes formed from experience. Here we evaluated that explanation by examining the influence of recent experience on participants' subsequent judgments of attractiveness. Participants first performed a memory task lasting 8 min in which all of the female faces to be remembered had their features placed in a low, average, or high position, depending on experimental condition. In what was described as a separate experiment, participants then moved the features of a female face with averaged features to their most attractive vertical location. The most attractive location was affected by the faces seen during the memory task, with participants who saw faces with features in the high position placing features in higher locations than participants who saw faces with features in either the low or average positions. The results demonstrate that perceptions of attractiveness are influenced by recent experience, and suggest that internal face prototypes are constantly being updated by experience.     

Fitting the child's mind to the world: adaptive norm-based coding of facial identity in 8-year-olds

In adults, facial identity is coded by opponent processes relative to an average face or norm, as evidenced by the face identity aftereffect: adapting to a face biases perception towards the opposite identity, so that a previously neutral face (e.g. the average) resembles the identity of the computationally opposite face. We investigated whether children as young as 8 use adaptive norm-based coding to represent faces, a question of interest because 8-year-olds are less accurate than adults at recognizing faces and do not show the adult neural markers of face expertise. We found comparable face identity aftereffects in 8-year-olds and adults: perception of identity in both groups shifted in the direction predicted by norm-based coding. This finding suggests that, by 8 years of age, the adaptive computational mechanisms used to code facial identity are like those of adults and hence that children's immaturities in face processing arise from another source.     

Developmental, Gender, and Health-Related Variations in Self-Competence and Depressed Mood Among School-Aged Urban Children with Asthma: A Pilot Study

This pilot study examined associations among asthma status, gender, self-competence, and depressed mood across 2 years of middle childhood in a sample of 57 urban children. Results revealed no differences across health status in self-competence and depressed mood. Girls showed a significant increase in levels of self-competence from Year -1 to 2. Higher levels of self-competence were associated with lower levels of depressed mood at Year 1, at Year 2, and from Year 1 to 2. Self-competence accounted for a larger amount of the variance in depressed mood for girls than for boys. Changes in levels of self-competence were significantly associated with changes in depressed mood for girls only. Results suggest meaningful gender-based differences in the socioemotional trajectories of school-aged children, which should be considered when designing preventative interventions in urban environments.     

The role of dual categorization and relative ingroup prototypicality in reparations to a minority group: An examination of empathy and collective guilt as mediators

In the current study, we investigate factors that facilitate or otherwise obstruct reparations of a perpetrating group (i.e. Muslims) to a victim group (i.e. Christians). The study (N = 200) reveals that among Muslim participants, the role of dual Abrahamic categorization in positively predicting reparation attitude towards Christians was mediated by the first group's prosocial emotions of empathy and collective guilt towards the latter group. In addition, relative Muslim prototypicality negatively predicted dual Abrahamic categorization and each of the two prosocial emotions. Empathy and collective guilt in turn mediated the role of relative ingroup prototypicality in negatively predicting reparation attitude. Moreover, as hypothesized, we found that the roles of empathy and collective guilt in predicting reparation intention, as manifested in participants' willingness to engage in collective action on behalf of the victim group, were not significant on their own, but were mediated by reparation attitude. These findings shed light on the importance of the relationship between the perpetrating group's shared identity with the victim group, reduced ingroup focus and its support for making reparations to the victim group. Theoretical implications, study limitations and practical strategies highlighting how to decrease relative Muslim prototypicality are discussed.     

Long trajectory for the development of sensitivity to global and biological motion

We used a staircase procedure to test sensitivity to (1) global motion in random-dot kinematograms moving at 4° and 18° s(-1) and (2) biological motion. Thresholds were defined as (1) the minimum percentage of signal dots (i.e. the maximum percentage of noise dots) necessary for accurate discrimination of upward versus downward motion or (2) the maximum percentage of noise dots tolerated for accurate discrimination of biological from non-biological motion. Subjects were adults and children aged 6-8, 9-11, and 12-14 years (n = 20 per group). Contrary to earlier research, results revealed a similar, long developmental trajectory for sensitivity to global motion at both slower and faster speeds and for biological motion. Thresholds for all three tasks improved monotonically between 6 and 14 years of age, at which point they were adult-like. The results suggest that the extrastriate mechanisms that integrate local motion cues over time and space take many years to mature.     

The Affect in Play Scale: confirmatory factor analysis in elementary school children

The aim of this paper was to study the construct validity of the Affect in Play Scale, an empirically based measure of pretend play, in a group of 519 Italian children ages 6 to 10 years. In confirmatory factor analysis, a correlated two-factor structure with a cognitive and an affective factor was identified. Possible differences in factor scores by sex and age were investigated but no significant differences were found.     

A comfortable witness is a good witness: rapport‐building and susceptibility to misinformation in an investigative mock‐crime interview

Major investigative interviewing protocols such as the Cognitive Interview recommend that investigators build rapport with cooperative adult witnesses at the beginning of a police interview. Although research substantiates the benefits of rapport‐building on the accuracy of child witness reports, few studies have examined whether similar benefits apply to adult witnesses. The present study investigated whether verbal rapport‐building techniques increase adult witness report accuracy and decrease their susceptibility to post‐event misinformation. One‐hundred eleven college adults viewed a videotaped mock‐crime, received post‐event misinformation (or correct information) about the crime, and were subsequently interviewed by a research assistant who built rapport (or did not build rapport) before recalling the mock‐crime. Results indicated that rapport‐building increased the quality of witness recall by decreasing the percentage of inaccurate and misinformation reported, particularly in response to open‐ended questions. We discuss implications and recommendations for law enforcement. Copyright © 2011 John Wiley & Sons, Ltd.
