Relationships between self-regulation and personality scores of persons with Down syndrome.

This study examined the associations of self-regulation (scores on self-assertion and self control) with personality traits for 76 persons with Down syndrome. Analysis shows self-assertion scores were correlated with scores for all personality traits. The correlations were significant with Emotionality and Playfulness for people with Down syndrome but not for those without Down syndrome (n=40). Self-control scores significantly correlated with scores on controlling and attachment for both groups. Emotionality was related to scores on self-control for students without Down syndrome but not for those with Down syndrome.     

Familial prevalence and coaggregation of schizotypy indicators: a multitrait family study

Schizophrenic probands (n = 17), their first-degree relatives (n = 61), and medically and psychiatrically screened normal control subjects (n = 18) were studied with structured interviews for DSM-III Axis I disorders and schizotypal personality disorder, questionnaire measures of schizotypy, measures of smooth-pursuit eye movement dysfunction, and attention dysfunction. Schizophrenic subjects scored abnormally on essentially all measures. Relatives differed significantly from control subjects on most measures. Correlational analyses indicate that many characteristics tested in these measures run together in families. The data are consistent with the hypothesis that a single vulnerability dimension or typology, presumably in part genetically transmitted, may account for phenotypically distinct abnormalities. These traits, taken together, may have joint usefulness for identifying persons with a predisposition to schizophrenia.     

Ocular motor indicators of executive dysfunction in fragile X and Turner syndromes

Fragile X and Turner syndromes are two X-chromosome-related disorders associated with executive function and visual spatial deficits. In the present study, we used ocular motor paradigms to examine evidence that disruption to different neurological pathways underlies these deficits. We tested 17 females with fragile X, 19 females with Turner syndrome, and 40 females with neither disorder who comprised the comparison group. Group differences emerged for both the fragile X and Turner syndrome groups, each relative to the comparison group: Females with fragile X had deficits in generating memory-guided saccades, predictive saccades, and saccades made in the overlap condition of a gap/overlap task. Females with Turner syndrome showed deficits in generating memory-guided saccades, but not during either the predictive saccade or gap/overlap task. Females with Turner syndrome, but not females with fragile X, showed deficits in visually guided saccades and anti-saccades. These findings indicate that different brain regions are affected in the two disorders, and suggest that different pathways lead to the similar cognitive phenotypes described for fragile X and Turner syndromes.     

Vocational interests and Big Five traits as predictors of job instability

Although empirical research on this topic is scarce, personality traits and vocational interests have repeatedly been named as potential individual level predictors of job change. Using a long-term cohort study (N = 291), we examined RIASEC interest profiles and Big Five personality scores at the beginning of the professional career as predictors of subsequent job changes, both internal as well as external, over the next 15 years. Overall, results provide additional evidence for an individual difference perspective on job instability, although our findings vary across instability variables. Consistent with previous research, external job changes in particular related to individual differences. Specifically, scores on Investigative, Artistic, Enterprising and Conventional scales showed to be the most important interest related predictors. With regard to Big Five personality traits, strongest associations were found with Agreeableness and Openness. In addition, facet level analyses proved to be useful to further clarify linkages between personality and job instability.     

Personality factors and posttraumatic stress: associations in civilians one year after air attacks

There is an ongoing debate on which risk factors for developing posttraumatic stress symptoms are more important--personality traits reflecting vulnerability, previous stressful experiences or characteristics of the traumatic event. In this study, posttraumatic stress symptoms and their relationship with personality traits, previous stressful experiences and exposure to stressful events during air attacks in Yugoslavia were investigated. The Millon Clinical Multiaxial Inventory (MCMI; Millon, 1983), Impact of Events Scale (IES; Horowitz, Wilner, & Alvarez, 1979), Life Stressor Checklist Revised (LSCL-R; Wolfe & Kimerling, 1997), and List of Stressors were administered to a homogeneous group of medical students 1 year after the attacks. In multiple regression analyses, compulsive and passive-aggressive personality traits and a higher level of exposure to stressors during air attacks independently predicted the degree of intrusion symptoms. Avoidance symptoms were predicted by avoidant personality traits and a higher exposure to stressors both previously in life and during the attacks. In the next step, we tested in analyses of variance whether personality traits, previous stressful experiences, and stressful events during attacks as independent variables interact in predicting intrusion and avoidance symptoms. For this, students were clustered into three groups depending on their predominant personality traits. In addition to direct predictive effects, there were significant interaction effects in predicting both intrusion and avoidance. The findings suggest that each of the tested factors, i.e., personality traits, previous stressful experiences, and exposure to traumatic events may have an independent and direct influence on developing posttraumatic stress. However, the effect of these factors cannot just be added up. Rather, the factors interact in their impact on posttraumatic stress symptoms. Bigger samples and longitudinal designs will be required to understand precisely how different personality traits influence response to stressful events.     

Mathematics learning disability in girls with Turner syndrome or fragile X syndrome

Two studies were carried out to examine the persistence (Study 1) and characteristics (Study 2) of mathematics learning disability (MLD) in girls with Turner syndrome or fragile X during the primary school years (ages 5-9 years). In Study 1, the rate of MLD for each syndrome group exceeded the rate observed in a grade-matched comparison group, although the likelihood of MLD persisting through the primary school years was comparable for all three groups. In Study 2, formal and informal math skills were compared across the syndrome groups, a normative group, and children from the normative group who had MLD. Few differences were observed between the Turner syndrome and normative groups. Despite having rote counting and number representation skills comparable to those in the normative group, girls with fragile X had difficulty with counting rules (e.g., cardinality, number constancy). However, this difficulty did not distingush them from the MLD group. Overall, counting skills appear to distinguish the Turner syndrome and fragile X groups, suggesting that the specificity of math deficits emerges earlier for fragile X than Turner syndrome.     

Use of the TAT in the Assessment of DSM-IV Cluster B Personality Disorders

The Social Cognition and Object Relations Scale (SCORS), developed by Westen, Lohr, Silk, Kerber, and Goodrich (1985), is a diagnostic instrument used to assess an array of psychological functioning by using clinical narratives such as the Thematic Apperception Test (TAT; Murray, 1943) stories. This study investigated the utility of the SCORS to differentiate between Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) antisocial personality disorder (ANPD), borderline personality disorder (BPD), narcissistic personality disorder (NPD), and Cluster C personality disorder (CPD). A sample of 58 patients was separated into four groups: ANPD (n = 9), BPD (n = 21; 18 with a primary BPD diagnosis and 3 with prominent borderline traits who met 4 of the 5 DSM-IV criteria necessary for a BPD diagnosis), NPD (n = 16; 8 with a primary NPD diagnosis and 8 with prominent narcissistic traits who met 4 of the 5 DSM-IV criteria necessary for a NPD diagnosis), and CPD (n = 12). These groups were then compared on the 8 SCORS variables by using 5 TAT cards (1, 2, 3BM, 4, and 13MF). Spearman-Brown correction for 2-way mixed effects model of reliability for the 8 SCORS variables ranged from .70 to .95. The results of categorical and dimensional analyses indicate that (a) the SCORS variables can be used to differentiate ANPD, BPD, and NPD; (b) the BPD group scored significantly lower (greater maladjustment) than did the CPD group on certain variables; (c) the BPD group scored significantly lower (greater maladjustment) than did the NPD group on all 8 SCORS variables; (d) the ANPD group scored significantly lower than did the NPD group on certain variables; (e) certain variables were found to be empirically related to the total number of DSM-IV ANPD, BPD, and NPD criteria; and (f) certain variables were found to be empirically related to Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) personality disorder scales. The results of this study are discussed in terms of clinical utility, conceptual, and theoretical implications.     

The Winding Paths of the Lonesome Cowboy: Evidence for Mutual Influences Between Personality,Subjective Health,and Loneliness

Prior research demonstrated influences of personality traits and their development on later status of subjective health and loneliness. In the present study, we intended to extend these findings by examining mutual influences between health‐related characteristics and personality traits and their development over time. German adults were assessed at two time points across 15 years (N_T1 = 654, N_T2 = 271; M_age at Time 1 = 24.39, SD = 3.69). Data were analyzed with multivariate structural equation models and a multivariate latent change model. Neuroticism was found to predict later levels and the development of subjective health and loneliness. While subjective health likewise predicted later levels of Neuroticism, loneliness was found to be predictive of later levels as well as the development of Neuroticism, Extraversion, and Conscientiousness. Correlated changes indicated that developing a socially more desirable personality is associated with slower declines in subjective health and slower increases in loneliness. The findings indicate that characteristics related to an individual's health are reciprocally associated with personality traits. Thus, the study adds to the understanding of the development of personality and health‐related characteristics.

Evidence for cortical dysfunction in spasmodic dysphonia: regional cerebral blood flow and quantitative electrophysiology

Cortical function was evaluated in 26 subjects with spasmodic dysphonia. Quantitative topographic electrophysiologic mapping (QTE) was employed to provide quantitative analyses of EEG spectra and auditory and visual long-latency evoked potentials. Single-photon emission computed tomography (SPECT) of the cerebral transit of Xenon-133 was used to evaluate regional cerebral blood flow. Left hemispheric abnormalities in cortical function were found by both techniques in 10 subjects and by at least one technique in 18 subjects. Right hemispheric abnormalities were observed by both techniques in 8 subjects and by at least one technique in 18 subjects. Most patients with cortical dysfunction in one hemisphere had cortical dysfunction in the other, while only 4 subjects had unilateral lesions as found by one of the two techniques. Eight subjects were normal by all measurements. Underlying structural abnormalities were detected by magnetic resonance imaging in 5/24 subjects. However, functional abnormalities (SPECT or QTE) were not observed at sites of structural abnormalities. SPECT and QTE were significantly related in identification of left hemispheric dysfunction (p = .037) with a trend in the right hemisphere (p = .070), and a significant congruence of SPECT and QTE findings occurred in the left anterior cortical quadrant (p = .011). These findings indicate that dysfunction of cortical perfusion and/or cortical electrophysiology is associated with spasmodic dysphonia in the majority of subjects studied.     

Measurement invariance of personality traits from a five-factor model perspective: multi-group confirmatory factor analyses of the HP5 inventory

Associations between personality and health may be influenced by contextual factors varying across studied cohorts. Moreover, measurement bias related to contextual factors could also influence these associations. Gender and age have been discussed as important contextual factors when studying personality and health outcomes. An examination of measurement invariance across gender and age may therefore be warranted. In the present study, measurement invariance across age and gender was examined for a five-factor model of personality traits in which scales have been included to operationalise lower-order traits related to health-behaviour or health outcomes. Using multi-group confirmatory factor analysis on a population based cohort (n= 5700), all important parameters of the measurement model were found to be invariant. On the basis of this invariant model, hypotheses of mean differences across age and gender in personality traits were tested. These results were discussed in relation to meta-analyses on personality change and gender differences in personality.

The Formation of Attitudes Toward New Immigrant Groups1

People often receive information about new immigrant groups prior to any direct contact with group members. However, it is not clear how this information shapes attitudes toward the groups. To explore this issue, 204 subjects were told about an unknown immigrant group that was presented as high or low in personal relevance. Subjects were then given positive or negative consensus information about the emotions that group members elicit from others, group members' personality traits, and group members' values. As expected, results indicated that the presentation of positive information about emotional reactions, personality traits, and values caused attitudes to be more favorable than did the presentation of negative information. Importantly, however, the combined impact of the emotion and personality trait information depended on whether the group was perceived to be of high or low personal relevance. Specifically, when the information about emotions and personality traits was similarly valanced (i.e., both were positive or both were negative), attitudes toward the group tended to be less favorable in the high personal relevance condition than in the low personal relevance condition. In contrast, when mixed information was presented (i.e., positive emotions and negative personality traits or negative emotions and positive personality traits), attitudes tended to be more favorable in the high personal relevance condition. In addition, attitudes, once formed, predicted further perceptions of the group and behavioral intentions toward group members. The implications of the findings for the reduction of prejudice toward new immigrant groups are discussed.     

INDIVIDUALITY IN PLANNING: MEANING PATTERNS OF PLANNING STYLES

The study dealt with the particular contents subjects apply in a cognitive task. The hypotheses were that the frequency of specific contents would be related to the subject's information processing tendencies assessed in terms of the meaning system (Kreitler and Kreitler), that each content variable would be related to a pattern of meaning variables and that in some cases these patterns would resemble in structural features those related to personality traits, particularly cognitive traits. The subjects, 50 undergraduates of both genders, were administered in separate sessions a standard meaning questionnaire, assessing tendencies to use the meaning variables, and 10 planning tasks, coded in terms of eight conceptually-based variables (categories of contents, e.g., emotional, quantitative) and five factorially-based variables (defined on the basis of a factor-analysis of all responses, e.g., concern for aesthetics and external appearance, formal administrative arrangements). The findings showed that each content variable was related to a particular pattern of meaning variables providing insight into its cognitive dynamics. Six conceptually-based variables were related to patterns similar to those related to traits, not only cognitive. Discussion focuses on implications for the study of contents and of traits.     

Why can't a man be more like a woman? Sex differences in Big Five personality traits across 55 cultures

Previous research suggested that sex differences in personality traits are larger in prosperous, healthy, and egalitarian cultures in which women have more opportunities equal with those of men. In this article, the authors report cross-cultural findings in which this unintuitive result was replicated across samples from 55 nations (N = 17,637). On responses to the Big Five Inventory, women reported higher levels of neuroticism, extraversion, agreeableness, and conscientiousness than did men across most nations. These findings converge with previous studies in which different Big Five measures and more limited samples of nations were used. Overall, higher levels of human development--including long and healthy life, equal access to knowledge and education, and economic wealth--were the main nation-level predictors of larger sex differences in personality. Changes in men's personality traits appeared to be the primary cause of sex difference variation across cultures. It is proposed that heightened levels of sexual dimorphism result from personality traits of men and women being less constrained and more able to naturally diverge in developed nations. In less fortunate social and economic conditions, innate personality differences between men and women may be attenuated.     

Psychological determinants of health and performance: the tangled web of desirable and undesirable characteristics.

Correlations were determined for male (n = 225) and female (n = 242) college students between sets of undesirable personality traits (anxiety, stress reactivity, anger, and alienation) and desirable personality traits (instrumentality, achievement strivings, and optimism measured by the Scheier-Carver [1987] Life Orientation Test), and a series of outcome variables related to health (self-reported health complaints and health maintenance behaviors and beliefs) and academic performance (academic expectations and actual grade point average). Significant correlations were found between many of the personality variables and the outcome variables. However, partial correlations revealed different relationships for the various criteria. With other variables held constant, health complaints were related to several undesirable characteristics, whereas health maintenance behaviors and beliefs were related to several desirable attributes. Only achievement strivings made an independent contribution in both sexes to the 2 measures of academic performance. The theoretical and methodological wisdom of using measures of multiple personality constructs and outcome variables is discussed.     

Impulsiveness and anxiety: Information processing and electroencephalograph topography

Within a general systems model of personality, we are currently studying impulsiveness and other personality traits using multitrait-multimethod multivariate designs. The research involves a wide spectrum of techniques in an effort to find consistent relationships among biological, cognitive, behavioral, and environmental correlates of the personality traits. The goal is to develop unique profiles of personality traits based on these four classes of measurements. Our research has demonstrated that impulsiveness and anxiety are personality traits that have loadings on two orthogonal higher order personality factors that we have labeled action-oriented and mood-feeling. From both an empirical research and a clinical viewpoint, we have identified three subtraits of impulsiveness: cognitive (Ic), motor (Im), and nonplanning (Inp). Inp is hypothesized to relate to frontal lobe brain processes, while Ic and Im are more related to neural mechanisms that (1) control performance on tasks with “timing-and-rhythm” demands and/or (2) are related to seizure disorders. High-impulsive subjects (especially when high on Ic and Im) are less efficient at performing a wide range of psychomotor tasks. We hypothesize that this inefficiency relates to the information-gating properties of the nervous system being out of “synch” with efficient performance of selected tasks. High-impulsive subjects are visual N100 event-related potential augmentors, which would be consistent with this dyssynchrony occurring in the early stages of information processing. We also hypothesize that impulsiveness is related to serotonin (high impulsiveness related to low serotonin levels). Our psychopharmacological-psychophysiological studies of information processing would be consistent with the latter hypothesis.
