Perceived regard explains self- esteem differences in expressivity

Baumeister, Tice, and Hutton proposed that individuals with low self-esteem (LSEs) adopt a more cautious, self-protective self-presentational style than individuals with high self-esteem (HSEs). The authors predicted that LSEs' self-protectiveness leads them to be less expressive-less revealing of their thoughts and feelings-with others than HSEs, and that this self-esteem difference is mediated by their perceptions of the interaction partner's regard for them. Two correlational studies supported these predictions (Studies 1 and 2). Moreover, LSEs became more expressive when their perceived regard was experimentally heightened-when they imagined speaking to someone who was unconditionally accepting rather than judgmental (Study 3) and when their perceptions of regard were increased through Marigold, Holmes, and Ross's compliment-reframing task (Study 4). These findings suggest that LSEs' expressiveness can be heightened through interventions that reduce their concerns about social acceptance.     

Extending parasite-stress theory to variation in human mate preferences

In this commentary we suggest that Fincher & Thornhill's (F&T's) parasite-stress theory of social behaviors and attitudes can be extended to mating behaviors and preferences. We discuss evidence from prior correlational and experimental studies that support this claim. We also reanalyze data from two of those studies using F&T's new parasite stress measures.     

A Communities of Practice Approach to the Synoptic Problem

Although the study of the Synoptic Problem has been the focus of scholarly attention for over two hundred years, the social learning theory known as Communities of Practice is a relatively recent phenomenon. This article describes a communities of practice approach to the study of the Synoptic Problem in an upper‐division undergraduate course at a private, liberal arts college. Students with little or no prior knowledge of the Synoptic Problem were introduced to the salient issues of the Synoptic Problem as well as a theoretical framework in which to interpret them. Data were collected using a variety of mixed methods, including pre‐ and post‐treatment tests, written survey questions, interviews, field notes, and focus group sessions. The results of this study suggest that a communities of practice approach can enhance students' knowledge of the Synoptic Problem and also foster an awareness of scholarly and personal presuppositions that influence the interpretation of the gospels.     

Revisiting “Kindergarten as academic boot camp”: a nationwide study of ability grouping and psycho-social development

We revisit Harry L. Gracey’s perspective of kindergarten as academic boot camp where, at school entry, children acquire the student role through a structured program of activities. We provide further insights into the crucial mechanisms of socialization that occur in U.S. kindergartens by examining the relationship between within-class ability grouping and attributes of children’s psycho-social development that are critical for school success. Using data from the Early Childhood Longitudinal Study (ECLS-K) and incorporating stratified propensity scores into multi-level models, our analyses link within-class ability grouping to student behaviors in a manner that supports the concerns raised by ability grouping critics. Children in low ability groups show slower development in approaches to learning than comparable ungrouped children. Children in high ability groups show more accelerated development in all psycho-social attributes considered (approaches to learning, interpersonal skills, self control and externalizing problem behaviors) than comparable ungrouped children. These asymmetrical findings suggest that children placed in high and low ability groups are socialized into different versions of the student role.     

Not all skilled readers have cracked the code: individual differences in masked form priming

This experiment investigated whether individual differences in written language proficiency among university students predict the early stages of lexical retrieval tapped by the masked form priming lexical decision task. To separate the contributions of sublexical facilitation and lexical competition to masked form priming, the effects of prime lexicality were directly compared for both transposed-letter (TL) primes (e.g., sung SNUG; salb SLAB) and neighbor primes (e.g., snag SNUG; sleb SLAB) in a sample of 100 university students assessed on measures of reading, spelling and vocabulary. The data for the whole sample showed facilitation from nonword primes, but inhibition from word primes. Linear mixed models including the individual difference measures showed that higher scores on a principal component that captured the shared variance among reading, spelling, and vocabulary were associated with both stronger inhibition from TL word primes and stronger facilitation from neighbor nonword primes. These findings are consistent with the lexical quality hypothesis of reading that predicts that skilled readers vary in the extent to which they have developed precisely specified orthographic representations.     

Loneliness accentuates age differences in cardiovascular responses to social evaluative threat

The effects of aging and loneliness on cardiovascular stress responses were examined in 91 young (18-30 years) and 91 older (65-80 years) normotensive adults. Participants completed the revised UCLA Loneliness Scale and a modified version of the Trier Social Stress Test. Piece-wise linear growth-curve analysis was used to model group differences in resting, reactivity, and recovery levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Replicating and extending prior research, analyses revealed age-related increases in resting SBP and DBP. Adjusting for demographics and health covariates, interactions were found for SBP in which age differences in stress reactivity and recovery were greater among lonely than nonlonely participants. Findings provide further evidence that loneliness interacts with age to augment cardiovascular risk to social evaluative threat.     

Anxiety, conscious awareness and change detection

Attentional scanning was studied in anxious and non-anxious participants, using a modified change detection paradigm. Participants detected changes in pairs of emotional scenes separated by two task irrelevant slides, which contained an emotionally valenced scene (the 'distractor scene') and a visual mask. In agreement with attentional control theory, change detection latencies were slower overall for anxious participants. Change detection in anxious, but not non-anxious, participants was influenced by the emotional valence and exposure duration of distractor scenes. When negative distractor scenes were presented at subliminal exposure durations, anxious participants detected changes more rapidly than when supraliminal negative scenes or subliminal positive scenes were presented. We propose that for anxious participants, subliminal presentation of emotionally negative distractor scenes stimulated attention into a dynamic state in the absence of attentional engagement. Presentation of the same scenes at longer exposure times was accompanied by conscious awareness, attentional engagement, and slower change detection.     

Effects of sleep on positive,negative and neutral valenced story and image memory

During sleep, emotional memories are preferentially strengthened. However, most studies on sleep and emotional memory focus on comparing negative valence with neutral valence stimuli. This study compared the sleep-dependent memory effects for stories and images, each comprising negative, neutral, and positive stimuli. It was hypothesized that a sleep effect would be seen for negatively and positively valenced stimuli. A novel story memory task (comprising three stories), and photographs from the Nencki Affective Picture database were presented for learning to 61 healthy adults (ages 18–25). They were tested for memory on the two tasks immediately, and then again after either a 2-hr nap (n = 31; 17 women, 14 men) or 2-hr wake period (n = 30; 13 women, 17 men). At second testing, the sleep condition had significantly better recall compared to the wake condition on both tasks. There was a relationship with valence only for the story task, with better performance for the sleep condition on the negatively and positively valenced texts, but not on the neutral text. There were no significant relationships between memory measures and sleep-stage duration and EEG power variables. The story memory findings support the hypothesis that memory consolidation prioritizes emotional memory, whether positively or negatively valenced.
