An assessment of the fakeability of self-report and implicit personality measures

Researchers are focusing on developing implicit measures of personality to address concerns related to the faking of self-report measures. The present study examined the validity and fakeability of Implicit Association Test (IAT) measures of personality self-concept in a repeated-measures design (N = 33). People’s predictions about how they represented themselves on the measures were also assessed. Results indicated that participants were able fake self-report measures when instructed to do so and that they could accurately predict how they represented themselves on these measures. Participants were also able to fake an IAT measure of Extraversion, but were unable to fake an IAT measure of Conscientiousness or predict how they represented themselves on either IAT measure.     

Effects of global and contextualized personality on relationship satisfaction

Researchers have made great strides in conceptualizing and assessing contextualized personality—how people’s personalities vary across different contexts (e.g., among friends, co-workers, and relationship partners). We investigated how global and contextualized personality traits are linked to relationship satisfaction. In Study 1, longitudinal associations between global and contextualized personality and relationship satisfaction were examined in a sample of adults in committed dating relationships. Study 2 investigated actor and partner effects of global and contextualized personality on relationship satisfaction in undergraduate couples. Study 3 used observer ratings of contextualized personality traits expressed in couples’ daily Instant Messages (IMs). These results demonstrate that contextualized personality—in particular neuroticism—is linked to the quality of both current and future romantic relationships.     

Effects of guided immune-imagery: The moderating influence of openness to experience

It is widely believed that personality has an important role in determining the effectiveness of guided imagery (GI) interventions. The primary aim of the current study was to examine whether the effect of GI on several outcome measures was dependent upon openness to experience, a theoretically relevant variable previously unexplored as a potential moderator. Thirty-five healthy participants were randomised to an animated imagery, verbal imagery or no-intervention control group, with imagery groups receiving 10 × 20 min sessions. Pre/post-assessments of cortisol, sleep, stress and creativity were administered along with the openness to experience scale. Regression analysis indicated a significant increase in cortisol and decrease in tiredness following verbal GI, but only for those high in openness. The efficacy of GI interventions may be dependent upon openness to experience and this variable should be accounted for in future studies.     

Why do narcissists take more risks? Testing the roles of perceived risks and benefits of risky behaviors

Much prior research demonstrates that narcissists take more risks than others, but almost no research has examined what motivates this behavior. The present study tested two potential driving mechanisms of risk-taking by narcissists (i.e., heightened perceptions of benefits and diminished perceptions of risks stemming from risky behaviors) by administering survey measures of narcissism and risk-taking to a sample of 605 undergraduate college students. Contrary to what might be expected, the results suggest that narcissists appreciate the risks associated with risky behaviors just as much as do less narcissistic individuals. Their risk-taking appears to instead be fueled by heightened perceptions of benefits stemming from risky behaviors. These results are consistent with a growing body of evidence suggesting that narcissists engage in some forms of potentially problematic behaviors, such as risk-taking, because of a surplus of eagerness rather than a deficit of inhibition.     

Gray matter density negatively correlates with duration of heroin use in young lifetime heroin-dependent individuals

Numerous studies have documented cognitive impairments and hypoactivity in the prefrontal and anterior cingulate cortices in drug users. However, the relationships between opiate dependence and brain structure changes in heroin users are largely unknown. In the present study, we measured the density of gray matter (DGM) with voxel-based morphometry in 30 lifetime heroin-dependent individuals who had abstained from drug use for 5 months, and 34 healthy participants. The DGM of the prefrontal, temporal and cingulate cortices significantly decreased in heroin addicts relative to the healthy group. Critically, partial correlation analysis, which controlled for age, education and gender factors as well as nicotine use and heroin abstinence duration, showed that the duration of heroin use negatively correlated with the DGM in heroin-dependent individuals. These results provide compelling evidence for structural abnormality in heroin-dependent individuals and further suggest that duration of heroin use is a critical factor leading to brain damage.     

Linking personality states,current social roles and major life goals

Employing an experience‐sampling design, the interplay between personality states, social roles and major life goals was examined as it unfolds in the stream of people's daily lives. Multilevel analyses revealed a considerable amount of both within‐ and between‐person variability in state expressions of personality traits justifying further examination of predictors at both levels of analyses. Roles proved as predictors of current personality states albeit effects differed significantly between individuals. Life goals accounted for between‐person differences in average personality states but were not effective in predicting differences in relations between personality states and roles. Altogether, findings testify to the viability of the employed research strategy to analyse the interplay between both dispositional and fluctuating influences on individuals' trait expressions in behaviour.

The New Person-Specific Paradigm in Psychology

ABSTRACT— Most research methodology in the behavioral sciences employs interindividual analyses, which provide information about the state of affairs of the population. However, as shown by classical mathematical-statistical theorems (the ergodic theorems), such analyses do not provide information for, and cannot be applied at, the level of the individual, except on rare occasions when the processes of interest meet certain stringent conditions. When psychological processes violate these conditions, the interindividual analyses that are now standardly applied have to be replaced by analysis of intraindividual variation in order to obtain valid results. Two illustrations involving analysis of intraindividual variation of personality and emotional processes are given.     

Personal and social support factors involved in students’ decision to participate in formal academic mentoring

In this study, we examined the role of personal and social support factors involved in students’ decision to participate in formal academic mentoring. Three hundred and eighteen students completing Grade 11 and planning to study sciences in college filled out a questionnaire and were then asked to participate in an academic mentoring program during their first year of college. A total of 150 students agreed to take part in this program (volunteers) and 168 declined the offer (non-volunteers). The overall findings support the hypothesis that academic mentoring is more attractive for some students than others depending on their personality, help-seeking attitudes, academic dispositions, perceived support from friends, and support available during the transition to college. These findings were discussed in light of the different mechanisms proposed by mentoring and social support literatures.     

Integrating five-factor model facet-level traits with the theory of planned behavior and exercise

ObjectivesThe purpose of this study was to examine direct, indirect, and moderating links between facet-level personality traits of the five-factor model, the theory of planned behavior (TPB) constructs [Ajzen, I. (1991). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50, 179–211.], and exercise behavior.DesignCross-sectional.MethodUniversity students (N = 507) completed the NEO-PI-R [Costa, P. T., McCrae, R. R. (1992). The NEO-PI-R personality inventory: Professional manual. Odessa, FL: Psychological Assessment Resources.], the Leisure-time Exercise Questionnaire [Godin, G., Shephard, R. J. (1985). A simple method to assess exercise behavior in the community. Canadian Journal of Applied Sport Science, 10, 141–146.], and measures assessing the TPB constructs.ResultsPreliminary analysis revealed the extraversion and conscientiousness facet-level traits of activity and self-discipline respectively were independent predictors of exercise behavior. An integrated structural model with both facet-level traits revealed that 46% of the variance in exercise behavior and 70% of the variance in intention was explained. Significant indirect effects of activity and self-discipline and the TPB constructs of affective attitude, instrumental attitude, and subjective norm, on exercise behavior through intention and perceived behavioral control were also observed. Finally, the anxiety facet trait of neuroticism significantly moderated the intention–behavior relationship.ConclusionsOur findings showed that the facet-level personality traits of activity and self-discipline are important motivational variables that link the TPB constructs to exercise behavior. Future research that integrates personality with the TPB within experimental interventions is warranted.
