Facilitation and disruption of lateralized syllable processing by unattended stimuli in the opposite visual field

The influence of lateralized unattended stimuli on the processing of attended stimuli in the opposite visual field can shed light on the nature of information that is transferred between hemispheres. On a cued bilateral task, participants tried to identify a syllable in the attended visual field, which elicits a left hemisphere (LH) advantage and different processing strategies by the two hemispheres. The same or a different syllable or a neutral stimulus appeared in the unattended field. Transmission of unattended syllable codes between hemispheres is symmetric, as revealed by equal interference for the two visual fields. The LH is more accurate than the RH in encoding unattended syllables, as indicated by facilitation in the left but not right visual field and a greater frequency of identifiable intrusions into the left than right field. However, asymmetric encoding strategies are different for attended and unattended syllables.     

Personality and Serum Lipids: Does Lifestyle Account for Their Concurrent and Long‐term Relationships

This study evaluates concurrent and over time associations of personality with measures of three serum lipids associated coronary heart disease morbidity, namely, high‐density lipoprotein cholesterol (HDL‐C), low‐density lipoprotein cholesterol and triglyceride (TRI). Participants were individuals who underwent a health examination at two points of time, T1 (N = 3835) and T2 (N = 2283), about 2.5 years apart. Personality was assessed by the Five‐Factor Model. Health, socioeconomic status and healthy lifestyle behaviours (smoking intensity, physical activity and body weight) were controlled. Regression analyses indicate that the personality factors of neuroticism, extraversion and conscientiousness are each significantly associated with HDL‐C and TRI, both concurrently and over time. However, most of these associations decreased to marginal significance when adjusted for body weight or physical activity as possible mediators. Both concurrent and over time associations of the openness personality trait with HDL‐C and TRI were significant and persisted after adjustment for measures of a healthy lifestyle. This study emphasizes the importance of collecting measures of a healthy lifestyle to better understand how personality might influence serum lipids.

Did Somebody See It? Applying the Verifiability Approach to Insurance Claim Interviews

We examined the application of the verifiability approach to insurance claim interviews. The verifiability approach states that truth tellers and liars differ from each other in terms of the number of details they give that can be verified. Eighty‐three true and false insurance claim statements, related to damage, theft, or loss, were coded in terms of ‘witnesses’ (was the incident witnessed by others) and ‘verifiability’ (the number of perceptual and contextual details provided that could be checked by the investigator). We found that the majority of liars, compared with half the truth tellers, described unwitnessed incidents. This difference between the groups allowed for the detection of liars only. Discrimination between liars and truth tellers based on the verifiability of details was not possible. The implications of these findings are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Childhood Maltreatment and its Effect on Parenting among High-Risk Parents

Research evidence indicates that a childhood history of maltreatment affects parental behaviors in adulthood. The aim of the study was to investigate the predictors for parental behaviors among individuals who reported a history of maltreatment. The current study investigated whether attachment styles, emotional regulation and cognitive appraisals of parenting predicted parental behaviors (positive vs. negative). The study also investigated the differential effects of abuse experiences in childhood (physical, sexual, emotional, and neglect) on parental behaviors. The participants were 213 high-risk Jewish and Arab parents of children aged six and under. Participants completed five self-report questionnaires assessing parental behaviors, childhood experiences of abuse and neglect, attachment styles, emotional regulation, and cognitive appraisal of parenthood. The regression analyses revealed that personal attributes such as ethnicity, childhood experience of emotional abuse/neglect, emotional regulation, and appraisal of parenting, predict negative parental behavior. Anxious attachment and childhood emotional abuse and neglect moderated the impact of parenthood appraisal on parenting behaviors. Although physical and sexual abuse had the highest impact on insecure attachment, emotional abuse/neglect had higher predictive power for non-positive parenting. Clinical interventions for improving the capacity for emotional regulation and parent-child relational skills are suggested.     

Distinctiveness in flashbulb memory: Comparative analysis of five terrorist attacks

The purpose of the present study was to find out whether a series of terrorist attacks, which share some common features, elicit flashbulb memories (of the personal circumstances in which the person first learned about these events) that are usually elicited by a single, unexpected, surprising, and personally important event. A total of 131 participants answered questions regarding details of five terrorist attacks that had taken place in Israel during the years 1995–1997. In addition, they assessed, for each of the five events, the number of overt rehearsals, and the degrees of emotional intensity, surprise, novelty, personal importance, and distinctiveness. Data analyses showed that most variables that are usually associated with the formation of flashbulb memories were also found in memories of the terrorist attacks that were judged by the participants as being distinctive. Distinctiveness may therefore be considered an important factor in the formation of flashbulb memories.     

The Across-Time Associations of the Five-Factor Model of Personality With Vigor and Its Facets Using the Bifactor Model

We tested hypothesized across-time associations of personality traits with the affective state of global vigor and its physical, emotional, and cognitive facets. The study was carried out in the context of work, where vigor represents a discrete, positive affective response to one's ongoing interactions with specific elements of the work environment. Our model was based on the bifactor approach to modeling second-order constructs in structural equation modeling. Data were gathered from 1,217 reportedly healthy respondents who underwent a periodical health examination at Time 1 (T1) and Time 2 (T2), about 24 months apart. We found that, independent of T1 and T2 global vigor, agreeableness and conscientiousness predicted both T1 and T2 levels of vigor's emotional facet, and openness predicted vigor's cognitive facet at both T1 and T2.     

Personality Traits and Body Weight Measures: Concurrent and Across‐Time Associations

We tested the possibility that the five‐factor model of personality is associated with three measures of body weight and with changes in their levels over time and that these associations are gender specific. The study was conducted at two points of time, Time 1 (2664 participants) and Time 2 (1492 participants), over approximately 4 years, controlling for gender, age, education, and having a chronic disease. Body weight was assessed by body mass index, waist circumference, waist‐to‐hip ratio, and the five‐factor model by Saucier's Mini‐Markers. Cross‐sectional regression results indicated that conscientiousness was negatively associated with the three body weight measures, whereas neuroticism and extraversion were positively associated with the three body weight measures. The longitudinal regression results indicate that extraversion was associated with an increase in two of the body weight measures. Neuroticism was associated with increase in all three body weight measures and more strongly for women than for men. Openness was associated with a decrease in all three body weight measures for women, but this association was not significant for men. These findings help identify personality traits that lead to risk of weight gain and point to the modifying role of gender. Copyright © 2013 John Wiley & Sons, Ltd.
