Internet dependence in the collegiate population: the role of shyness.

Low sensation seeking and loneliness have been associated with collegiate Internet dependence. In an attempt to further explicate the factors associated with collegiate Internet dependence, interpersonal shyness (both online and in face-to-face [FTF] interactions) was explored. An online questionnaire was used to assess Internet dependency and shyness. The results demonstrated the predicted interaction such that shyness level for nondependents did not differ online or in FTF interactions. However, dependents' shyness was greater in FTF interactions relative to online interpersonal exchanges. The results were discussed in terms of how various Internet resources (e.g., e-mail, chat rooms, and instant messages) can be used to ameliorate shyness and how such negatively reinforced behavior could foster dependence.     

Social exchange styles: Measurement,validation, and application

Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit‐seeking and cost‐vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members' subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Rational Emotive Behaviour Therapy: A Positive Perspective

Through his development of Rational Emotive Behaviour Therapy (REBT), Albert Ellis was a major contributor to the development of cognitive behaviour therapy. This article reviews key aspects of REBT, the distinction between unhealthy and healthy emotions, and the role irrational and rational beliefs play in relation to these emotions. As with other areas of psychology, the focus of REBT over the years has been dominated by negative emotional experiences. In an attempt to address this and further develop REBT, the present article reviews recent claims from the realm of social psychology that positive illusions promote mental health. Consequently, it is proposed that a similar dichotomy of healthy and unhealthy positive emotions also exists, and a basic framework for working with this positive dichotomy is introduced.     

Accountability for others,perceived resources,and well being: Convergent restricted non‐linear results in two samples

This two‐sample investigation examined the influence of perceived resources on the form and magnitude of the relationships between accountability for others (AFO) and job tension and job satisfaction. Employing resource theory, we hypothesized that the non‐linear relationship between AFO and job tension would surface only for individuals high in perceived resources, whereas the association between these constructs would be positive and linear for individuals low in perceived resources. A similar relationship was hypothesized for AFO and job satisfaction in which the non‐linear effect would arise for individuals high in perceived resources, and negative linear effects would emerge for those low in perceived resources. Data from two samples (N= 201; N= 182) provided support and replication for the hypotheses. Implications of the results and directions for future research are discussed.     

Towards an Understanding of Change in Physical Activity from Pregnancy Through Postpartum

OBJECTIVE: The purpose of this paper was to describe the rationale, data collection, and proposed analyses for examination of mediators of change in physical activity from pregnancy to postpartum among a cohort of pregnant women. METHOD: The Pregnancy Infection and Nutrition 3 (PIN3) Study enrolled 2006 pregnant women into the cohort from 2001 to 2005. All women lived in central North Carolina upon enrollment. Physical activity was assessed using a self-reported one week recall, measured twice during pregnancy and once each at 3- and 12-months postpartum. On a subset of women, one-week accelerometer measures were also collected during the two postpartum time periods. Potential mediators (intrapersonal, interpersonal, community) were collected during pregnancy and postpartum through interviews and take home questionnaires. RESULTS: To assess mediation of physical activity among our cohort, we will first describe change in physical activity and the mediators, as well as their associations, through pregnancy into the postpartum period. Following this, the product of coefficients approach will be applied to examine whether each measure had indirect effects on change in physical activity. Each individual level mediator will be examined one at a time and across the time points in which it was available. The Sobel standard error approximation formula will be used to test for significance of the mediation effect. CONCLUSIONS: This study will provide evidence to develop appropriate interventions targeted at physical activity and will help focus efforts on the appropriate time periods between pregnancy and postpartum.     

Metacognition of emotional face recognition

While humans are adept at recognizing emotional states conveyed by facial expressions, the current literature suggests that they lack accurate metacognitions about their performance in this domain. This finding comes from global trait-based questionnaires that assess the extent to which an individual perceives him or herself as empathic, as compared to other people. Those who rate themselves as empathically accurate are no better than others at recognizing emotions. Metacognition of emotion recognition can also be assessed using relative measures that evaluate how well a person thinks s/he has understood the emotion in a particular facial display as compared to other displays. While this is the most common method of metacognitive assessment of people's judgments of learning or their feelings of knowing, this kind of metacognition--"relative meta-accuracy"--has not been studied within the domain of emotion. As well as asking for global metacognitive judgments, we asked people to provide relative, trial-by-trial prospective and retrospective judgments concerning whether they would be right or wrong in recognizing the expressions conveyed in particular facial displays. Our question was: Do people know when they will be correct in knowing what expression is conveyed, and do they know when they do not know? Although we, like others, found that global meta-accuracy was unpredictive of performance, relative meta-accuracy, given by the correlation between participants' trial-by-trial metacognitive judgments and performance on each item, were highly accurate both on the Mind in the Eyes task (Experiment 1) and on the Ekman Emotional Expression Multimorph task (in Experiment 2).     

Memory in traumatic brain injury: The effects of injury severity and effort on the Wechsler Memory Scale‐III

This study examined the effects of traumatic brain injury (TBI) on Wechsler Memory Scale‐III (WMS‐III) performance. Since poor effort potentially contaminates results, effort was explicitly assessed and controlled using two well‐validated cognitive validity indicators, the Portland Digit Recognition Test (PDRT) and Reliable Digit Span (RDS). Participants were 44 mild TBI patients with good effort, 48 mild TBI patients with poor effort, and 40 moderate–severe TBI patients with good effort. A dose–response relationship between injury severity and WMS‐III performance was demonstrated. Effect size calculations showed that the good effort mild TBI patients did not differ from normal (average Cohen's d= 0.07) while moderate–severe TBI had a moderate effect on WMS‐III scores (average Cohen's d=?0.52). Consistent with previous literature, the moderate–severe TBI group scored the lowest on WMS‐III Visual indices. Effort had a larger effect than injury severity on WMS‐III scores (average Cohen's d=?1.27). Clinical implications of these findings are discussed.
