Sex differences in the links between attractiveness, self-esteem and the body

Two studies were conducted to determine: if the links between the body and self-perceived attractiveness and self-esteem for men and women differ. Following evolutionary and social learning theories, affective and cognitive links were hypothesized for women's attractiveness while no links were hypothesized for men's attractiveness. Additionally, affective links were expected for women's self-esteem while no links were expected for men's self-esteem. The results obtained supported these hypotheses. Findings are discussed in terms of the societal value placed on women's attractiveness and evolutionary theory.     

Escalation in groups: Focus on information sampling

The purpose of this experiment was to examine if groups escalate more than individuals when information is not distributed to all group members. The experiment also attempted to replicate Bazerman, Beekun, and Schoorman's (1992) findings, that participants with high responsibility escalate more than participants with low responsibility. The task was a modified version of the Heeley Store Case (Bazerman et al., 1992). The dependent measures fell into three categories: rewards, appropriateness of layoff/demotion, and forecasted future performance. The results showed little support for the hypotheses. First, high responsibility participants escalated significantly more than low responsibility candidates for only one of the six measures. This may have been due to the fact that all participants felt responsible for their decisions. For the other dependent variables, the effect was either not significant or in the wrong direction. Second, no significant interaction was found between responsibility and decision-making context (individual, groups with all shared information, and groups with shared and unshared information). We then analyzed the data using a measure of felt responsibility as a covariate. The interaction between felt responsibility and decision-making context was significant only for layoff decision. For all of the other measures, no significant interaction was found. One possible reason why our hypotheses were not supported may have been that the groups felt a diffusion of responsibility. Larger groups may have also demonstrated the effects of group processes more effectively. No clear conclusions can be made regarding the influence of information sampling on escalation. An earlier version of this paper was presented at the 1998 meetings of the American Psychological Society.     

Computation of Conditional Probability Statistics by 8-Month-Old Infants

A recent report demonstrated that 8-month-olds can segment a continuous stream of speech syllables, containing no acoustic or prosodic cues to word boundaries, into wordlike units after only 2 min of listening experience (Saffran, Aslin, & Newport, 1996). Thus, a powerful learning mechanism capable of extracting statistical information from fluent speech is available early in development. The present study extends these results by documenting the particular type of statistical computation–transitional (conditional) probability–used by infants to solve this word-segmentation task. An artificial language corpus, consisting of a continuous stream of trisyllabic nonsense words, was presented to 8-month-olds for 3 min. A postfamiliarization test compared the infants' responses to words versus part-words (trisyllabic sequences spanning word boundaries). The corpus was constructed so that test words and part-words were matched in frequency, but differed in their transitional probabilities. Infants showed reliable discrimination of words from part-words, thereby demonstrating rapid segmentation of continuous speech into words on the basis of transitional probabilities of syllable pairs.     

Imaginal correlates of self-reported fear and avoidance behavior

Two analogue studies explored the relationship between the content of subjects' imagery and both behavioral avoidance and self-reports of fear. In the first study, reports of aversive imagery in a fearful situation were much more frequent among high- as compared to low-avoidance subjects. Reports of aversive imagery were found significantly associated with both fear and avoidance behavior. In the second study, findings were extended, indicating that imagery content is associated with fear and avoidance when subjects imagine themselves in a fearful situation as well as when they are actually in one. This suggested some degree of functional equivalence between imagined and real situations. However, no relationship was found between image clarity and either fear or avoidance. Since imagery appears to play an important role in mediating fearful behavior, manipulation of imagery might serve as an effective treatment strategy.     

The Influence of Contextual Factors on Afro-American and Euro-American Children's Performance: Effects of Movement Opportunity and Music

The present study sought to further establish that contextual factors informed by certain postulated cultural experiences could influence performance on a learning task. Towards this end, low income Afro-American and Euro-American children learned to pair pictures in an acquisition context that allowed for them to coordinate movement with music (High Movement Expressive [HME]) and in an acquisition context which allowed for little movement opportunity and no music (Low Movement Expressive [LME]). Children were subsequently tested for picture pair retention in a context where music was present or in a context where music was absent. The findings revealed that Afro-American children's tested performance was superior with the HME acquisition context, while Euro-American children's performance was superior with the LME context. In addition, music present at testing context seemed to have an independent enhancing effect only on Afro-American children's performance. The cultural and educational implications of these findings are discussed as are recommendations for future research.     

A plausible role of imagination in pretend play,counterfactual reasoning,and executive functions

A notable observation is the similarities in the cognitive processes of pretend play (PP) and counterfactual reasoning (CFR) as both involve thinking about alternatives to reality. It is argued by Weisberg and Gopnik (Cogn. Sci., 37, 2013, 1368) that alternative thinking in PP and CFR is underpinned by an imaginary representational capacity but few studies have empirically investigated this link. We use a variable latent modelling approach to test a hypothetical model of the structural relationship of PP and CFR predicting that if PP and CFR are cognitively similar; they should have similar patterns of associations with Executive Functions (EFs). Data were collected on PP, CFR, EFs and Language from 189 children (M = 4.8 years, males = 101, females = 88). Confirmatory factor analyses showed that measures of PP and CFR loaded onto single latent constructs and were significantly correlated (r = .51, p = .001) with each other. Hierarchical multiple regression analyses revealed that EF accounted for unique significant variance in both PP (β = 21) and CFR (β = 22). The results of the structural equation modelling revealed that the data were a good fit for the hypothetical model. We discuss the plausible role of a general underlying imaginative representational capacity to explain similarities in the cognitive mechanisms of different states of alternative thinking like PP and CFR.     

Male Reference Group Identity Dependence: Support for Construct Validity

This research study examined correlates of male identity statuses as postulated in Wade's (1998) theory of male reference group identity dependence. The Reference Group Identity Dependence Scale (RGIDS; Wade & Gelso, 1998) was correlated with measures of identity aspects (personal, social, and collective), belongingness, and a universal-diverse orientation. Based on the responses of 172 predominantly middle-class undergraduate college men (59% White, 15% Asian American or Pacific Islander, 13% African American, 4% Hispanic, and 9% other race/ethnicity, e.g., biracial, Arab American, Egyptian American), as predicted, the No Reference Group status negatively related to collective identity and social connectedness; the Reference Group Dependent status positively related to social identity and social connectedness; and the Reference Group Nondependent status positively related to personal identity, collective identity, social connectedness, and a universal-diverse orientation toward others.     

Prevalence and correlates of depressive symptoms following traumatic brain injuries in children.

The prevalence and correlates of depressive symptoms following childhood traumatic brain injuries (TBI) were examined using data drawn from a prospective longitudinal study. Participants included 38 children with severe TBI, 51 with moderate TBI, and 55 with orthopedic injuries (OI). Assessments occurred shortly after injury (baseline) and at 6- and 12-month follow-ups. Children completed the Child Depression Inventory (CDI). Parents rated depressive symptoms using the Child Behavior Checklist (CBC), with baseline ratings reflecting premorbid status. Assessments also included measures of children's neurocognitive functioning and the family environment. The three groups did not differ overall in self-reported symptoms on the CDI, but did display different trends over time. The three groups did not differ on parent ratings of premorbid depressive symptoms on the CBC, but parents reported more depressive symptoms in the TBI groups than in the OI group at 6- and 12-month follow-ups. Child and parent reports were correlated for children in the TBI groups, but not for those in the OI group. Depressive symptoms were related to socioeconomic status in all groups. Socioeconomic status also was a significant moderator of group differences, such that the effects of TBI were exacerbated in children from more disadvantaged homes. Although self-reports of depressive symptoms were related inconsistently to children's verbal memory, parent reports of depressive symptoms were unrelated to IQ or verbal memory. The findings suggest that TBI increases the risk of depressive symptoms, especially among more socially disadvantaged children, and that depressive symptoms are not strongly related to post-injury neurocognitive deficits.     

Longitudinal Experience-Wide Association Studies—A Framework for Studying Personality Change

The importance of personality for predicting life outcomes in the domains of love, work, and health is well established, as is evidence that personality traits, while relatively stable, can change. However, little is known about the sources and processes that drive changes in personality traits and how such changes might impact important life outcomes. In this paper, we make the case that the research paradigms and methodological approaches commonly used in personality psychology need to be revised to advance our understanding of the sources and processes of personality change. We propose Longitudinal Experience-Wide Association Studies as a framework for studying personality change that can address the limitations of current methods, and we discuss strategies for overcoming some of the challenges associated with Longitudinal Experience-Wide Association Studies. © 2020 European Association of Personality Psychology
