Early puzzle play: a predictor of preschoolers' spatial transformation skill

Individual differences in spatial skill emerge prior to kindergarten entry. However, little is known about the early experiences that may contribute to these differences. The current study examined the relation between children's early puzzle play and their spatial skill. Children and parents (n = 53) were observed at home for 90 min every 4 months (6 times) between 2 and 4 years of age (26 to 46 months). When children were 4 years 6 months old, they completed a spatial task involving mental transformations of 2-dimensional shapes. Children who were observed playing with puzzles performed better on this task than those who did not, controlling for parent education, income, and overall parent word types. Moreover, among those children who played with puzzles, frequency of puzzle play predicted performance on the spatial transformation task. Although the frequency of puzzle play did not differ for boys and girls, the quality of puzzle play (a composite of puzzle difficulty, parent engagement, and parent spatial language) was higher for boys than for girls. In addition, variation in puzzle play quality predicted performance on the spatial transformation task for girls but not for boys. Implications of these findings as well as future directions for research on the role of puzzle play in the development of spatial skill are discussed.     

Ritualistic,Theistic, and Existential Spirituality: Initial Psychometric Qualities of the RiTE Measure of Spirituality

An expanded model to conceptualize sacred human experiences is discussed wherein the term Spirituality is broadened to include: (1) Ritualistic Spirituality, (2) Theistic Spirituality, and (3) Existential Spirituality. However, a measure incorporating this expanded model does not yet exist. A 67-item self-report questionnaire was developed and data were collected from 1,301 undergraduate students. A series of factor analytic procedures yielded a three-factor structure consistent with the guiding theoretical model and refinement produced three 10-item subscales. Evidence for construct validity and sound psychometric properties was indicative of a reliable, valid, and unique tool to assess the multidimensional nature of spirituality.     

Preferential processing of threatening facial expressions using the repetition blindness paradigm

Background: Neuroanatomical evidence suggests that the human brain has dedicated pathways to rapidly process threatening stimuli. This processing bias for threat was examined using the repetition blindness (RB) paradigm. RB (i.e., failure to report the second instance of an identical stimulus rapidly following the first) has been established for words, objects and faces but not, to date, facial expressions. Methods: 78 (Study 1) and 62 (Study 2) participants identified repeated and different, threatening and non-threatening emotional facial expressions in rapid serial visual presentation (RSVP) streams. Results: In Study 1, repeated facial expressions produced more RB than different expressions. RB was attenuated for threatening expressions. In Study 2, attenuation of RB for threatening expressions was replicated. Additionally, semantically related but non-identical threatening expressions reduced RB relative to non-threatening stimuli. Conclusions: These findings suggest that the threat bias is apparent in the temporal processing of facial expressions, and expands the RB paradigm by demonstrating that identical facial expressions are susceptible to the effect.     

The Influence of Social Status on Token Women Leaders' Expectations About Leading Male-Dominated Groups

Prior research has shown that women report mostly negative expectations about being a gender-token in male-dominated work groups. We speculate that this is partially caused by the socially ascribed status devaluation of women. In this study we investigated the degree to which elevated social status may lessen negative expectations of gender-token women assigned to leadership positions. Sixty-three undergraduate women participated in 1 of 3 tokenism conditions: (1) nontoken, (2) gender-token, and (3) high-status gender-token. In all conditions participants were led to believe that they would be leading a group of men in a decision-making exercise. Leader expectations were then assessed. The results suggest that increased social status may help prevent gender-token women from developing negative expectations about interactions with male-dominated work groups.     

Optimism and Hope After Multiple Disasters: Relationships to Health-Related Quality of Life

Natural and technological disasters are devastating events for individuals and communities. The authors examined the role of optimism and hope in predicting health indicators in a sample of disaster survivors who were exposed to Hurricanes Katrina and Rita in 2005. Participants were noncoastal residents, current coastal residents, and current coastal fishers who were also economically impacted by the 2010 BP Deepwater Horizon oil spill. All participants completed measures of optimism, hope, and the SF-36 Health Survey, which provides summary scores for mental and physical health. Logistic regressions indicated that optimism and hope were independently and positively associated with better mental health (OR = 1.21; 95% CI: 1.10, 1.32 and OR = 1.11; 95% CI: 1.05, 1.17 respectively). Neither optimism nor hope were significantly associated with physical health when considered alone. However, optimism interacted with prior lifetime trauma, where optimism only significantly predicted physical health for those with higher previous trauma scores. These results provide new evidence of optimism and hope as protective factors that may positively impact mental health after multiple disasters.     

Hippocampal theta-dependent eyeblink classical conditioning: coordination of a distributed learning system

Richard F. Thompson's study of the neurobiological substrates of learning and memory has been a career-long endeavor, chosen early and pursued with uncompromising depth and breadth. His systematic mapping of the major brain systems and mechanisms involved in eyeblink classical conditioning (EBCC) established the essential role of the cerebellum. Investigations of the interactions between the hippocampus and cerebellum are critically important to this literature, given the essential involvement of these structures in trace EBCC as well as an important modulatory role of the hippocampus in delay EBCC. Hippocampal theta (3-7Hz) oscillations are known to reflect a functional state that influences both the timing of unit firing and the potential for neural plasticity in the hippocampus and other structures. Herein we present a brief summary of research demonstrating the behavioral enhancement due to theta and the underlying neurobiological correlates in both hippocampus and cerebellum during EBCC. Hippocampal and cerebellar local field potentials (LFPs) show that these distantly interconnected brain structures become precisely synchronized when conditions favor rapid behavioral acquisition. Our results suggest a major role for theta in coordinating the widely distributed memory system for trace EBCC. These and other important findings reflect Thompson's own work and his early-career mentoring of scientists whose contributions to the EBCC literature have ensured his major and lasting impact on the neurobiology of learning and memory.     

Being well at work: the impact of organizational climate and social identity on employee stress and self-esteem over time

In organizational psychology, staff perceptions of organizational climate have been found to be an important predictor of employee outcomes, such as employee stress. However, only a small pool of research has investigated the psychological mechanism that underpins the relationship, and no past literature has explored how the relationship persists over time. This paper uses the social identity approach to investigate whether social identification predicts and mediates the relationship between staff perceptions of organizational climate and their levels of stress and self-esteem over time. Employing a sample of public school teachers, the study was conducted over two years (N = 281, 65 schools). The results indicated that social identification fully mediated the relationship between organizational climate and self-esteem longitudinally but showed no significant relationship with stress. The implications of these findings are discussed, with recommendations for future research.     

Factorial structure of pathological personality as evaluated by peers

This study explored how individuals apply features of personality disorders (PDs) to peers. Members of groups nominated peers who exhibited symptoms for each of the 10 PDs in the DSM-IV. Data were gathered in 2 samples: 1st-year college students (n = 1,440) and Air Force recruits (n = 2,075). The peer method reliably identified group members exhibiting specific PD features. Factor analyses identified a clearly interpretable structure relevant to the pathological personality constructs being assessed. The structure replicated well across samples and showed expected relationships to broader models of normal personality. However, cross-method correlations of factor scores were only moderate, suggesting that peer reports are reliably different from self-reports regarding the presence of pathological personality traits.
