Effects of Socioeconomic Status (SES) Information on Cognitive Ability Inferences: When Low-SES Students Make Use of a Self-Threatening Stereotype

Two studies tested whether students' socioeconomic status (SES) and academic achievement level moderate their use of the SES stereotype (i.e., the belief that the low-SES individuals are intellectually inferior to their high-SES counterparts). In Study 1, low versus high achievers with a low versus a high SES were given social class information (derived from a pilot study) about several targets and were then asked to infer these targets' memory ability. In Study 2, participants were given memory performance information about several targets and were then asked to infer these targets' possessions and cultural activities (i.e., SES indicators). In both studies, only the low-SES students generated stereotype-consistent inferences.     

With suspicious (but happy) minds: Mood's ability to neutralize the effects of suspicion on persuasion

Although investigations into the independent effects of mood and suspicion are plentiful, work examining their interactive impact on persuasion is nonexistent. To address this void in the literature, we consider how positive mood can affect the influence of suspicion on persuasion. In doing so, we investigate the potential for positive mood to neutralize the suspicion that consumers associate with sales agents in an interpersonal persuasion context. Two studies provide converging evidence of this neutralization effect. The theoretical implications of these findings are discussed as are avenues for future work in this area.     

Children's and adolescents' perception of the authenticity of smiles

Recently, Thibault and colleagues described the Duchenne marker as a cultural dialect for the perception of smile authenticity. The current study had the goal to follow up on this finding and to investigate the cues that French Canadian children use to evaluate the authenticity of smiles from members of three ethnic groups. The authenticity of six smiles differing in intensity and presence of orbicularis oculi (Duchenne marker) was rated by 1206 children from 4 to 17 years of age. No differences were found as a function of encoder group. All children perceived medium Duchenne smiles as more authentic than equally intense medium non-Duchenne smiles. Furthermore, results suggest a decrease in the reliance on intensity across the age span. Younger children use the intensity marker along the whole continuum to infer authenticity. In contrast, older children (14- to 17-year-olds) rated all smiles that did not contain the Duchenne marker as roughly equally low in authenticity.     

Comparison of perceptual and motor latencies via anticipatory and reactive response times

To compare the timing of perceptual and motor decisions, distinct tasks have been designed, all of which have yielded systematic differences between these two moments. These observations have been taken as evidence of a sensorimotor dissociation. Inasmuch as the distinction between perceptual and motor decision moments is conceptually warranted, this conclusion remains debatable, since the observed differences may reflect the dissimilarity between the stimulations/tasks used to assess them. Here, we minimize such dissimilarities by comparing response time (RT) and anticipatory RT (ART), an alternative technique with which to infer the relative perceptual decision moments. Observers pressed a key either in synchrony with the third of a sequence of three stimuli appearing at a constant pace (ART) or in response to the onset of this third stimulus presented at a random interval after the second (RT). Hence, the two stimulation sequences were virtually identical. Both the mean and the variance of RT were affected by stimulus intensity about 1.5 times more than were the mean and the variance of ART. Within the framework of two simple integration-to-bound models, these findings are compatible with the hypothesis that perceptual and motor decisions operate on the same internal signal but are based on distinct criteria, with the perceptual criterion lower than the motor one.     

The relationship of work stressors and emotional support to strain in police officers

This study tested whether quantity and quality of social support and two sources of work stress (organizational stressors and job risk) predicted work strain in police officers, a high-risk occupational group. The participants were 135 police officers from a large metropolitan law enforcement agency who responded to questionnaires for assessing work stress, social support, exhaustion, and other strain symptoms. Emotional support and work stressors accounted directly for significant variance in emotional exhaustion, depersonalization, and symptom frequency. Conflicted relationships, which are a source of both work stress and support, also contributed to strain. In contrast to previous findings, a reverse buffering effect for social support did not contribute to predicting strain. Stress management programs for police and other high-stress occupations should target increasing emotional support from supervisors and peers, and reducing conflict in job and family relationships.     

Means—ends problem-solving skills,life stress,and social support as mediators of adjustment in the normative transition to high school

Examined the transition of adolescents from middle school to high school through a longitudinal research design. Consistent with other studies, results indicate that the transition is associated with declines in grade point average and attendance, and that these changes persist or worsen over the course of the freshman year. Life stress and social support from family, friends, and school personnel each showed expected relationships with some outcome variables, though these varied in pattern and magnitude. Furthermore, there was some indication that these sources could be used in multivariate analyses in assessing their relationship to outcomes. Finally, means-ends problem-solving skills did not predict levels of posttransition support. Results are seen as supporting a differential model of the role of individual and environmental resources in the high school transition, especially with regard to the negative changes in grades and attendance and the pattern of correlations between social support sources and outcomes.     

Specificity and Abstraction of Examples: Opposite Effects on Fixation for Creative Ideation

Fixation is one of the major obstacles that individuals face in creative idea generation contexts. Several studies have shown that individuals unintentionally tend to fixate to the examples they are shown in a creative ideation task, even when instructed to avoid them. Most of these studies used examples formulated with high level of specificity. However, no study has examined individuals’ creative performance under an instruction to diverge from given examples, when these examples are formulated with a high level of abstraction. In the present study, we show that (a) instructing participants to avoid using common examples when formulated with a high level of specificity increases fixation; whereas (b) instructing participants to avoid such examples while using a more abstract level for stating these common examples—such as a categorization of these examples—mitigates fixation and doubles the number of creative ideas generated. These findings give new insights on the key role of categorization in creative ideation contexts.     

The influence of object size and surface shape on shape constancy from stereo

The failure of shape constancy from stereoscopic information is widely reported in the literature. In this study we investigate how shape constancy is influenced by the size of the object and by the shape of the object's surface. Participants performed a shape-judgment task on objects of five sizes with three different surface shapes. The shapes used were: a frontoparallel rectangle, a triangular ridge surface, and a cylindrical surface, all of which contained the same maximum depth information, but different variations in depth across the surface. The results showed that, generally, small objects appear stretched and large objects appear squashed along the depth dimension. We also found a larger variance in shape judgments for rectangular stimuli than for cylindrical and ridge-shaped stimuli, suggesting that, when performing shape judgments with cylindrical and ridge-shaped stimuli, observers rely on a higher-order shape representation.     

More emotional facial expressions during episodic than during semantic autobiographical retrieval

There is a substantial body of research on the relationship between emotion and autobiographical memory. Using facial analysis software, our study addressed this relationship by investigating basic emotional facial expressions that may be detected during autobiographical recall. Participants were asked to retrieve 3 autobiographical memories, each of which was triggered by one of the following cue words: happy, sad, and city. The autobiographical recall was analyzed by a software for facial analysis that detects and classifies basic emotional expressions. Analyses showed that emotional cues triggered the corresponding basic facial expressions (i.e., happy facial expression for memories cued by happy). Furthermore, we dissociated episodic and semantic retrieval, observing more emotional facial expressions during episodic than during semantic retrieval, regardless of the emotional valence of cues. Our study provides insight into facial expressions that are associated with emotional autobiographical memory. It also highlights an ecological tool to reveal physiological changes that are associated with emotion and memory.     

Behavioural Problems in Children with Headache and Maternal Stress: Is Children's Attachment Security a Protective Factor?

Headache is a potentially disabling condition involving enduring pain that negatively influences the quality of family life. Behavioural problems are more common in children with headache and are potentially associated with higher levels of parental stress. The aim of this study was to evaluate the extent to which children's behavioural problems were associated with maternal stress and how the child's perception of security in the maternal attachment relationship moderates this association. Seventy‐one school‐aged children with headache (headache group (HG), age M = 9.8 years old, SD = 1.3) and 71 children from a low‐risk normative population (control group (CG), age M = 9.2 years old, SD = 1) and their mothers were involved in the study. Mothers' reports of children's behavioural problems were associated with higher maternal stress in the caring task both in the HG and in the CG. Results also showed that the HG was more at risk for behavioural problems, whereas no difference between groups was detected for parenting stress and for attachment insecurity. In children with headache, perception of attachment security decreased the strength of the association between maternal stress and externalizing behavioural problems. Secure attachment may provide children with headache and their parents with support in managing the negative emotions that arise in the context of significant health issues. Implications for practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
