Comorbidity of Personality Disorders and Somatization Disorder: A Meta-analytic Review

Meta-analysis of studies assessing the comorbidity of somatization disorder (SD) with one or more personality disorders (PDs) revealed that-contrary to the assertions of the Diagnostic and Statistical Manual of Mental Disorders (4th edition, text revision)-SD co-occurs with the majority of Axis II PDs. Although comorbidity effect sizes (rs) linking SD with paranoid PD and obsessive-compulsive PD were small, effect sizes for antisocial, borderline, narcissistic, histrionic, avoidant, and dependent PD yielded rs about or above 0.20. Comorbidity information in future versions of the DSM should be revised to reflect the greater number of PDs empirically linked with SD.

Contrasting the ironic monitoring and motivational explanations of postsuppressional rebound

Suppressing a thought often results in postsuppressional rebound, that is, a subsequent increase in the incidence of the suppressed thought. The present study was dcsigned to distinguish between two explanations of rebound: Wegner's 1994 ironic monitoring theory and Liberman and Forster's 2000 motivational account. Participants (99 Deakin University students) first suppressed, then expressed, thoughts of a white bear. In some conditions, a delay--presented as occurring either intentionally or unintentionally--between suppression and expression was introduced. In other conditions, participants concurrently completed a memory task and were encouraged to antribute the difficulty of suppression either to this task or to the requirement of suppression. An intentional delay, but not an unintentional delay, reduced rebound, while attributing difficulty to the suppression requirement was associated with greater rebound than was attributing it to the memory task. The results are interpreted as supporting Liberman and Forster's motivational account of rebound.     

Does the brain calculate value?

How do people choose between options? At one extreme, the 'value-first' view is that the brain computes the value of different options and simply favours options with higher values. An intermediate position, taken by many psychological models of judgment and decision making, is that values are computed but that the resulting choices depend heavily on the context of available options. At the other extreme, the 'comparison-only' view argues that choice depends directly on comparisons, with or even without any intermediate computation of value. In this paper, we place past and current psychological and neuroscientific theories on this spectrum, and review empirical data that have led to an increasing focus on comparison rather than value as the driver of choice.     

Personality and American state differences in obesity prevalence

The study was conducted to determine whether state obesity-prevalence rates can be predicted by state differences in residents' levels on the Big Five personality variables (O. P. John & S. Srivastava, 1999). State obesity prevalence was the mean percentage of the state population from 2000 to 2005 with a body mass index > or = 30.0 as assessed by the Behavioral Risk Factor Surveillance System (Centers for Disease Control and Prevention, 2010), which currently interviews more than 350,000 adults annually. State neuroticism, extraversion, agreeableness, conscientiousness, and openness z scores, based on the responses of 619,397 residents to an Internet survey from 1999 to 2005, were taken from P. J. Rentfrow, S. D. Gosling, and J. Potter (2008). Alaska, Hawaii, and North Dakota had scores outside -3 and +3 standard deviations on at least 1 variable and were excluded as outliers. For the 47 remaining states, state obesity prevalence was significantly correlated with neuroticism (.35), agreeableness (.38), openness (-.44), socioeconomic status (-.74), white percentage (-.34), and urbanization (-.43). Multiple regression analysis showed that socioeconomic status could account for 54.0% of the criterion variance and that agreeableness, neuroticism, and openness together could account for another 17.1%.     

Internalized Misogyny as a Moderator of the Link between Sexist Events and Women’s Psychological Distress

This study examined the relationship between internalized misogyny and two other forms of internalized sexism, self-objectification and passive acceptance of traditional gender roles. In addition, it examined the moderating role of internalized misogyny in the link between sexist events and psychological distress. Participants consisted of 274 heterosexual women who were recruited at a large southern university in the United States and completed an online survey. Results indicated that internalized misogyny was related to, but conceptually distinct from self-objectification and passive acceptance. Findings also indicated that greater experiences of sexist events were associated with higher levels of psychological distress. In addition, internalized misogyny intensified the relationship between external sexism and psychological distress.     

Word learning in deaf children with cochlear implants: effects of early auditory experience

Word-learning skills were tested in normal-hearing 12- to 40-month-olds and in deaf 22- to 40-month-olds 12 to 18 months after cochlear implantation. Using the Intermodal Preferential Looking Paradigm (IPLP), children were tested for their ability to learn two novel-word/novel-object pairings. Normal-hearing children demonstrated learning on this task at approximately 18 months of age and older. For deaf children, performance on this task was significantly correlated with early auditory experience: Children whose cochlear implants were switched on by 14 months of age or who had relatively more hearing before implantation demonstrated learning in this task, but later implanted profoundly deaf children did not. Performance on this task also correlated with later measures of vocabulary size. Taken together, these findings suggest that early auditory experience facilitates word learning and that the IPLP may be useful for identifying children who may be at high risk for poor vocabulary development.     

What Makes the Political Personal? Openness,Personal Political Salience,and Activism

ABSTRACT People who attach personal meaning to social and political events or are high in Personal Political Salience (PPS) are more likely to engage in political activism ( Duncan & Stewart, 2007 ). Although research suggests that PPS is consequential for activism, we know little about its origins or, more generally, about indirect effects of personality on activism. In this study we examined the possibility that the personality trait of Openness to Experience may be one source of PPS and an indirect predictor of activism. In addition, we proposed that Openness would also be directly related to political activism in young adults but not in middle‐aged and older adults. Analyses confirmed these predictions in cross‐sectional and over‐time data from six samples. We argue that Openness may predispose some individuals both to find personal meaning in distant political events and to engage in social activism in their youth.     

The impact of smart driving aids on driving performance and driver distraction

In-vehicle information systems (IVIS) have been shown to increase driver workload and cause distraction, both of which are causal factors for accidents. This simulator study evaluates the impact that two prototype ergonomic designs for a smart driving aid have on workload, distraction and driving performance. Scenario complexity was also manipulated as an independent variable. Results showed that real-time delivery of smart driving information did not increase driver workload or adversely affect driver distraction, while also having the positive effect of decreasing mean driving speed in both the simple and complex driving scenarios. Subjective workload was shown to increase with task difficulty, as well as revealing important differences between the two interface designs. The findings are relevant to the development and implementation of smart driving interface designs in the future.
