Assessment of cognitive function across pregnancy using CANTAB: A longitudinal study

Significant changes in endogenous plasma hormone levels are required to sustain pregnancy which provides a unique opportunity to study their effect on cognitive function.     

Proactive Personality at Work: Seeing More to Do and Doing More?

Purpose

The purpose of this study was to develop and test a model relating proactive personality to job behaviors (task and citizenship behaviors) through the intervening mediator of perceived role breadth.

Design/methodology/approach

Survey data were obtained from 530 faculty members in 69 U. S. research universities.

Findings

Proactive personality was positively related to task behavior and OCB. Perceived role breadth mediated the relationship between proactive personality and OCB, but did not mediate the relationship between proactive personality and task behavior. Despite not viewing their role more broadly, individuals higher in proactive personality engaged more frequently in both task behavior and OCB; and also worked more hours per week.

Implications

Having a better understanding of proactive individuals is important in terms of managing them. Because these individuals tend to do more in their jobs and subsequently work more hours, they may be more susceptible to burnout and may require additional help in determining priorities and balancing their work and lives.

Originality/value

This is the first study to show that proactive personality is positively related to the frequency with which these individuals engage in task and citizenship behavior. Although role breadth is generally an antecedent of such job behaviors, individuals higher in proactive personality engage more frequently in task behaviors regardless of whether or not they perceive them as part of their role. This is one of the first studies to show that working more hours each week is a potential cost of having a proactive personality.     

Posttraumatic stress disorder is associated with limited executive resources in a working memory task

Patients with posttraumatic stress disorder (PTSD) can show declines in working memory. A dual-task design was used to determine whether these impairments are linked to executive control limitations. Participants performed a Sternberg memory task with either one or four letters. In the dual-task condition, the maintenance period was filled with an arrow flanker task. PTSD patients were less accurate on the working memory task than were controls, especially in the dual-task condition. In the single-task condition, both groups showed similar patterns of brain potentials from 300 to 500 ms when discriminating old and new probes. However, when taxed with an additional task, the event-related potentials (ERPs) of the PTSD group no longer differentiated old and new probes. In contrast, interference resolution processes in both the single- and dual-task conditions of the flanker task were intact. The lack of differentiation in the ERPs reflects impaired working memory performance under more difficult, dual-task conditions. Exacerbated difficulty in performing a working memory task with concurrent task demands suggests a specific limitation in executive control resources in PTSD.     

Emotional expression and physiology in European Americans and Hmong Americans

Ethnographic and clinical observations suggest that Asians are less expressive than European Americans. To examine whether this difference emerged in online emotional responding, 50 Hmong Americans (HAs) and 48 European Americans (EAs) were asked to relive past episodes of intense happiness, pride, love, anger, disgust, and sadness. Facial behavior and physiological reactivity were measured. For most emotions, more cultural similarities than differences were found. There were some exceptions: During happiness, fewer HAs than EAs showed non-Duchenne smiles (i.e., "social" smiles), despite similarities in reported emotional experience and physiological reactivity. Within-group differences between "less Hmong" and "more Hmong" HAs were also found. Implications of these findings for our understanding of culture-emotion relations are discussed.     

Are Deaf Dating Scripts Really Different from Those of Their Hearing Peers?

An initial study found that Deaf participants have a different definition of a date than the Traditional Sex Script (TSS). In the TSS, the man is viewed as the initiator who pushes for sex and the woman is expected to limit sex if they do not want to have intercourse; neither of these ideas were included in Deaf participants’ responses when asked what happens on a typical date. These findings may relate to early experiences in childhood. At an early age, hearing children are exposed to the TSS through popular culture. Deaf children are not exposed to these cues at the same level because of their lack of communication access. Here we compare Deaf college students to hearing college students to further investigate these issues using a more quantitative design.     

Auditory access,language access,and implicit sequence learning in deaf children

Developmental psychology plays a central role in shaping evidence‐based best practices for prelingually deaf children. The Auditory Scaffolding Hypothesis (Conway et al., 2009) asserts that a lack of auditory stimulation in deaf children leads to impoverished implicit sequence learning abilities, measured via an artificial grammar learning (AGL) task. However, prior research is confounded by a lack of both auditory and language input. The current study examines implicit learning in deaf children who were (Deaf native signers) or were not (oral cochlear implant users) exposed to language from birth, and in hearing children, using both AGL and Serial Reaction Time (SRT) tasks. Neither deaf nor hearing children across the three groups show evidence of implicit learning on the AGL task, but all three groups show robust implicit learning on the SRT task. These findings argue against the Auditory Scaffolding Hypothesis, and suggest that implicit sequence learning may be resilient to both auditory and language deprivation, within the tested limits.

Taking religion to heart: the relationship between the Five Factor Model and the New Indices of Religious Orientation among religious students

The relationship between religious orientation and personality has been investigated using several different measures and diverse samples. As part of a larger study, 114 undergraduate students were given the Duke University Religion Index (DUREL) to include only those participants who were considered religious. The final sample of 80 participants were given the NEO Personality Inventory-Revised (NEO PI-R) and the New Indices of Religious Orientation (NIRO). Based on the results of the bivariate correlations, higher levels of intrinsic religious orientation were associated with greater Agreeableness and Conscientiousness. Multivariate analyses further revealed that Agreeableness was the most important personality variable when predicting intrinsic and quest religious orientations, with higher levels of Agreeableness predicting greater intrinsic and lower quest orientations. While lower levels of Neuroticism predicted greater intrinsic orientation, higher levels of Neuroticism predicted greater quest orientations. Higher Conscientiousness predicted greater intrinsic and lower quest orientations. Implications of these findings are discussed.     

“Inside out”: Appraisals for achievement emotions from constructive,positive, and negative feedback on writing

Even with the recent surge of research on achievement emotions, few studies have investigated emotions in feedback situations and the appraisals associated with such emotions. The purpose of this study was to examine emotion appraisals of constructive criticism, negative, and positive feedback, to aid us in determining whether these appraisals differed by feedback type. In a task asking them to provide open-ended responses as they imagined receiving feedback on a writing task, undergraduates (N?=?270) gave reasons for why they might experience unpleasant emotions from positive feedback and pleasant emotions from negative feedback along with reasons for both pleasant and unpleasant emotions emanating from constructive feedback. Open coding of responses yielded categories for each emotion-feedback pairing that, across all emotions, were collapsed into five appraisal categories: feedback suggests ways to improve, a mismatch between feedback and task exists, feedback targets the self or one’s ability, feedback says something about the relationship between feedback giver and receiver, and the task is judged for its value. Distributions of appraisal categories distinguished constructive feedback from positive and negative feedback. Implications are drawn for control-value theory and for classroom feedback practices.
