Psychopathic personality traits are linked to reduced false memories for negative events

Individuals scoring high on psychopathic personality traits process emotional material to a different extent than individuals with few psychopathic traits. Evidence exists that these individuals have impaired emotional memory. The question arises whether this emotional memory impairment has ramifications for the production of emotional false memories. In the present study, we investigated the production of false and true memories for emotional events in a community sample (N = 120) of individuals varying in psychopathic traits (evaluated with the Psychopathic Personality Inventory–Revised [PPI-R] questionnaire). The fearless dominance (FD) component of psychopathy interacted with the emotional impact of to-be-remembered events in the production of false memories, showing fewer negative false memories with increasing levels of FD. At the subjective level, negative false memories were not perceived as vivid memory experiences in high FD individuals. Concerning true memories, higher scores in cold-heartedness were related to fewer true memories for neutral and negative (but not positive) events. These results show that individuals with high psychopathy traits – in particular, FD – do not have a general emotional memory impairment but they process negative material in a different way than individuals with low psychopathic traits and thus are less susceptible to producing false memories for negative events.     

Increasing acquaintanceship and complementarity of behavioral styles and personality traits among college roommates

Robert Carson's principle of complementarity asserts that the behavioral styles of interaction partners tend to complement each other by encouraging individuals to act opposite in terms of dominance and similar in terms of warmth. The principles of complementarity further hypothesize that as relationships progress through multiple interactions, the behavioral styles of its members will be altered to increase complementarity. To examine this acquaintanceship hypothesis, the behavioral styles and personalities of 102 college roommate dyads were assessed after living together for 2 weeks and again after living together for 15 weeks. Consistent with the acquaintanceship hypothesis, after 2 weeks the behavioral styles of roommates did not complement each other; however, after 15 weeks, the behavioral styles of roommates strongly complemented each other. In contrast to the change in complementarity observed in roommates' behavioral styles, participants' perceptions of their own personalities were relatively unaffected by the personalities of their roommates.     

Counterproductive sustainability behaviors and their relationship to personality traits

This article introduces the concept of ‘counterproductive sustainability behaviors’ (CSB) as a novel expression of counterproductive work behaviors (CWB). It presents a short measure of CSB that applies the construct of counterproductivity to employee behaviors in the environmental sustainability domain. Personality assessments were administered to three independent samples—employed students, experienced employees, and job applicants—to investigate the relationship between personality and CSB (self-reports and other-rated), and to compare results to those obtained in the prediction of traditional CWB.     

Normality evaluations and their relation to personality traits and well-being

Despite frequent discussions of what it means to be normal in clinical, social, and personality psychology theory, the characteristics of individuals who call themselves normal are little understood. In 5 studies, the authors investigated various hypotheses concerning the nature of normality evaluations. The authors add to recent evidence that normality evaluations represent a distinct dimension of evaluative judgments, showing self-judgments of being normal (versus strange) to be relatively independent from self-judgments of being average (versus unique). Normality evaluations showed positive relations with communal traits such as agreeableness, conscientiousness, and emotional stability, and were negatively related to openness to experience. Supporting a broader hypothesis that normality evaluations may be involved in directing or motivating personality development processes, normality evaluations were positively associated with well-being and a sense of fitting in with one's peers, and individuals who felt abnormal felt a heightened sense that they needed to improve their personality. Finally, the personality correlates of normality evaluations were found to change over the lifespan, largely in parallel with the actual mean-level development of personality traits with age.     

Age at earliest reported memory: associations with personality traits, behavioral health, and repression

The present study examined relationships between the age at earliest memory and the personality traits and behavioral health of 107 undergraduates. Participants answered questions on their earliest memory and completed the Myers-Briggs Type Indicator (MBTI) and a medical history form. Analyses indicated that continuous scores on two MBTI scales (Sensing-Intuition and Judging-Perceiving) were inversely related to age at earliest memory as were participant's self-reported drug and alcohol problems, emotional and psychological symptoms, accident rates, physical symptoms, and satisfaction with health. Respondents who reported first memories at or after 7 years of age (i.e., approximately 1 SD above the mean age at recalled memory) were classified as repressors. Repressors scored in the Sensing and Judging directions on the MBTI and reported significantly fewer emotional symptoms, accidents, psychological symptoms, and less health satisfaction than nonrepressors. Results are consistent with the age at earliest memory and repression literature and support the use of earliest memory age as an index of repression.     

Predicting borderline personality disorder features from personality traits, identity orientation, and attachment styles in Italian nonclinical adults: issues of consistency across age ranges

The aims of this study were to assess whether Borderline Personality Disorder (BPD) features could be predicted by Big Five traits, impulsivity, identity orientation, and adult attachment patterns in a sample of 1,192 adult nonclinical participants, and to evaluate the consistency of these regression models across four age groups (<30 years, 30-39 years, 40-49 years, and >50 years, respectively). In the full sample, measures of neuroticism (N), impulsivity, and anxious insecure attachment were substantial predictors of BPD features (adjusted R(2) = .38, p < .001). Attachment scales were significant predictors of BPD features across all age groups, but different scales were relevant in different age groups. Our results suggest that in nonclinical populations, BPD may represent a complex constellation of personality traits and disturbed attachment patterns.     

Thinking styles in relation to personality traits: an investigation of the Thinking Styles Inventory and NEO-PI-R

This study is an investigation of the Sternberg-Wagner Thinking Style Inventory (TSI), with regard to cross-cultural replication and relation to the five-factor personality model (FFM). TSI and NEO-PI-R were administered to 107 participants from USA and 114 participants from Norway. Inter-correlations between NEO-PI-R dimensions and TSI-scales and factors were not very strong, few exceeding 0.40, and the correlations were in predicted directions. Joint factor analyses of TSI and NEO-PI-R showed that TSI covers variance that NEO-PI-R does not explain. Thus, it is argued that the thinking styles give an independent contribution beyond FFM dimensions. However, TSI did not relate to FFM in the same manner in the two samples. Finally, the TSI-scales and factors were replicable across samples by Procrustes rotation. The question whether thinking style may be regarded as a valid and reliable construct is discussed.     

Two-year stability of Psychosis Proneness Scales and their relations to personality disorder traits

Two-year stability of Physical Anhedonia (PhA), Perceptual Aberration (PER), and Magical Ideation (MI) scale scores and their relation to personality disorder traits were examined. Additionally, the effects of a time-lagged (prospective) versus concurrent measurement of psychosis proneness and personality disorder traits were studied to examine the specificity of MI, PER, and PhA. With a non-college-student sample (n = 404), stability for PhA was sufficiently high, but for PER and MI, stability was moderate to low. The correlations between personality disorder traits and psychosis proneness scales demonstrate that simultaneous assessment leads to a more nonspecific pattern of associations for MI and PER, although the correlation to schizotypal personality disorder traits were the highest. However, prospectively only MI, but neither PER nor PhA, emerged as a significant predictor for schizotypal and paranoid personality disorder traits in multiple-regression analysis. This suggests that MI may allow for a more specific assessment of psychosis proneness than PER.     

Public attitudes toward sex offenders and their relationship to personality traits and demographic characteristics

The present study examined public attitudes toward the sentencing, treatment, management, and perceived dangerousness of sex offenders. Seventy‐eight university undergraduates completed a 25‐item attitude toward sex offenders survey developed for the present study, along with a five‐factor measure of personality (NEO Personality Inventory – Revised), a demographic questionnaire, and the Paulhus Deception Scale, to control for social desirability. While participants most frequently endorsed the belief that sentences were not sufficiently severe, they tended to espouse treatment and risk management alternatives to longer sentences and eschewed exceptionally severe punishments (e.g., surgical castration). Participants estimated high rates of sexual recidivism (59%), although they also estimated significantly lower recidivism rates for treated offenders. Results of a principle components analysis suggested that participant attitudes comprised two broad domains: systems attitudes (e.g., law enforcement, corrections, justice) and rehabilitative attitudes. Although few demographic differences emerged in participant attitudes, ‘openness to experience’ and ‘agreeableness’ each significantly predicted more rehabilitative attitudes, while contrary to expectations, ‘extraversion’ was significantly associated with more negative systems‐related attitudes. The results provide support that personality traits may be linked to important social attitudes, including those toward sex offenders. Copyright © 2010 John Wiley & Sons, Ltd.     

General and specific traits of personality and their relation to sleep and academic performance

Few studies have examined the links between personality variables and sleep and their combined effect on specific real-world outcomes. Participants in this study completed numerous personality, sleep, and performance measures; we examined the associations among these measures. Personality was assessed using the Five-Factor Model. The personality trait of Conscientiousness (especially its facet of Achievement Striving) was a substantial predictor of academic performance. Analyses of the sleep variables revealed three distinct constructs: quantity, quality, and schedule. Sleep quantity showed few interesting correlates. In contrast, sleep quality was associated with greater well-being and improved psychological functioning, whereas sleep schedule (i.e., average rising and retiring times) was significantly related to Conscientiousness, such that conscientious individuals maintain earlier schedules.     

Shy teens and their peers: Shyness in respect to basic personality traits and social relations

The main purpose of this paper was to examine shyness in teenagers from two perspectives: in terms of its relations with basic personality traits and in terms of its influence on the processes that occur in the social networks of high school students. First, we found that shyness was negatively predicted by extraversion and positively by neuroticism. Second, using exponential random graph models we demonstrated that shyness across network effects was similar to reversed extraversion (introversion): Both negatively predicted the number of outgoing relations, whereas they did not affect the number of incoming relations. We discuss the issue of locating shyness in the space of personality traits, supporting the relevance of ascribing it to introversion.     

Behavioral expression of learned fear in rats is appropriate to their age at training,not their age at testing

Recent research has shown that learned fear emerges in a response-specific sequence. For example, an odor conditioned stimulus (CS) previously paired with shock elicits behavioral expressions of fear like avoidance at a younger age than it elicits other behavioral expressions of fear like potentiation of the startle response (Richardson, Paxinos, & Lee, 2000). In the present study, the question of whether learned fear is expressed in a manner appropriate to the animal's age at training or its age at testing was explored in three experiments, all using a within-subjects design. The results suggest that learned fear is expressed in a manner appropriate to the rat's age at training, not its age at testing. The Discussion section focuses on the implications of these findings for (1) the developmental analysis of memory and (2) the idea that an aversive CS elicits a central state of fear.     

The rank-order consistency of personality traits from childhood to old age: a quantitative review of longitudinal studies

The present study used meta-analytic techniques to test whether trait consistency maximizes and stabilizes at a specific period in the life course. From 152 longitudinal studies, 3,217 test-retest correlation coefficients were compiled. Meta-analytic estimates of mean population test-retest correlation coefficients showed that trait consistency increased from .31 in childhood to .54 during the college years, to .64 at age 30, and then reached a plateau around .74 between ages 50 and 70 when time interval was held constant at 6.7 years. Analysis of moderators of consistency showed that the longitudinal time interval had a negative relation to trait consistency and that temperament dimensions were less consistent than adult personality traits.     

On individual differences in person perception: raters' personality traits relate to their psychopathy checklist-revised scoring tendencies

This study investigated raters' personality traits in relation to scores they assigned to offenders using the Psychopathy Checklist-Revised (PCL-R). A total of 22 participants, including graduate students and faculty members in clinical psychology programs, completed a PCL-R training session, independently scored four criminal offenders using the PCL-R, and completed a comprehensive measure of their own personality traits. A priori hypotheses specified that raters' personality traits, and their similarity to psychopathy characteristics, would relate to raters' PCL-R scoring tendencies. As hypothesized, some raters assigned consistently higher scores on the PCL-R than others, especially on PCL-R Facets 1 and 2. Also as hypothesized, raters' scoring tendencies related to their own personality traits (e.g., higher rater Agreeableness was associated with lower PCL-R Interpersonal facet scoring). Overall, findings underscore the need for future research to examine the role of evaluator characteristics on evaluation results and the need for clinical training to address evaluators' personality influences on their ostensibly objective evaluations.     

Family psychological factors in relation to children's asthma status and behavioral adjustment at age 4

The objectives of this study were to determine whether family psychosocial factors influenced asthma development by age 4, and whether family factors and early wheezing illness were associated with behavioral adjustment at age 4. Participants were 98 children enrolled in an intervention study at 9-24 months and followed to age 4. Baseline evaluations assessed infants' respiratory illness severity, family psychosocial characteristics, and parental risk factors for asthma development. Active asthma categorization at age 4 utilized both parent report and objective data. Parents completed the Child Behavior Checklist (CBCL). Caregiver single-parent status, a composite of baseline family stresses, and early wheezing illness severity were associated with active asthma at age 4. The contribution of prenatal smoke exposure and early hospitalization to active asthma varied with racial/ethnic group membership. Maternal mental health and family stresses predicted CBCL scores at age 4, whereas early illness severity and hospitalization were unrelated to CBCL scores. CBCL scores were not elevated for children with active asthma at age 4. Family factors consistent with a negative emotional environment were associated with both active asthma and adjustment problems at age 4, suggesting that both outcomes may be influenced by a common factor.     

The group assessment of interpersonal traits (GAIT): Differentiation of measures and their relationship to behavioral response modes

GAIT performances of undergraduates were rated by peers and professsional clinical psychologists from video tape. Two additional measures; Potential for Clinical Effectiveness, and Insight into the Client's Problem, were included with GAIT measures of Openness, Empathy, Acceptance, and Outgoing and were also rated. GAIT ratings of Empathy, Acceptance, Potential for Clinical Effectiveness were not well differentiated. The behavioral response modes of each participant in the Understander's role were analyzed and correlated with GAIT measures, Potential and Insight. Empathy was correlated with reflecting feelings and advice-giving questions and negatively correlated with dysfunctional questions and silence. Acceptance was correlated with nonverbal attending behavior and negatively correlated with dysfunctional questions. Outgoing was positively correlated with information-gathering questions and total questions. Insight was correlated with reflecting feelings and negatively correlated with silence. An Understander who was rated high on Potential for Clinical Effectiveness was active, made statements about or asked questions pertaining to the Discloser's feelings, asked advice giving questions, tended to have infrequent silences during the interaction, and did not ask digressive or dysfunctional questions. Finally, the importance of Outgoing suggests the salience of an activity dimension in judged Clinical Potential.     

Maternal speech to infants at 1 and 3 months of age

The goal of this study was to assess maternal speech and in relation to changes in infant social behavior occurring around the second month post birth. Sixty infants interacted with their mother at 1 and 3 months of age in a face-to-face context. At 3 months, infants gazed, smiled, and positively vocalized significantly more than at 1 month. These findings point to a transition in infant social behavior at around the second month post birth. In addition, maternal speech to infants increased between these times in both amount and complexity, possibly in response to an increase in infant social behavior. Maternal speech was related to infant positive vocalizing at 3 months, suggesting mothers especially monitored infant vocalizing at 3 months. Individual differences in maternal speech were stable across visits.     

Children's memories for events relating to treatment for eye cancer: Influence of age at loss of eye

Treatment for retinoblastoma frequently involves removal of at least one eye in the first 5 years. Variation in age of treatment leads to the assumption that children's later verbal accessibility of early traumatic memories may vary, with some children having less opportunity to make sense of their condition. Video recordings were made of 17 children who had undergone enucleation either before 24 months (n = 8) or after 24 months (n = 9) involved in “hospital play'' using props designed to elicit talk about “eyes.” The hypothesis that a larger number of verbalizations about medical procedures would occur in children enucleated after 24 months than before 24 months was supported. Children enucleated after 24 months engaged in significantly more talk about enucleation and/or examination under anesthetic whereas none of the children enucleated in infancy talked about these medical events. The outcome supports the view that there is a transition around 24 months in the extent to which children can have verbal access to previous traumatic memories. The design of interventions needs to take into account that children enucleated in infancy have less opportunity for later verbal access to early memories of traumatic events than those treated later, leading to possible misconceptions about their own condition.
