Self-awareness training associated with personality traits and sex: a pilot study

107 volunteers learning Reiki-Do self-awareness techniques participated in this study. Results indicate that personality traits in healthy participants might be affected by specific self-awareness training, such as Reiki-Do, with participants' sex playing an independent role.     

Relationships between personality structure, structure of word meaning, and cognitive ability: a study of cultural mechanisms of personality

Native-born Estonian men (N=912), 17-68 years old, participated in a study on relationships between personality characteristics, dominant structure of word meaning ("everyday concepts" thinking or "scientific concepts" thinking), and level of cognitive ability. Individuals who primarily used everyday concepts thinking or who possessed relatively low levels of cognitive ability did not reveal a coherent Big Five personality structure, whereas individuals who primarily used scientific concepts thinking or possessed high levels of cognitive ability did. Thus, personality may be shaped by a cultural factor--word meaning structure. Earlier studies, which seem to support the idea that Big Five personality structure is a biologically determined human universal, suffer from serious sampling problems and insufficient data analyses.     

Differences of prefrontal cortex activity between picture-based personality tests: a near-infrared spectroscopy study

This study reports on brain activity induced by picture-based personality tests. Near-infrared spectroscopy is a newly developed, noninvasive technology in neuroimaging that can measure brain activity through blood volume changes. We measure the prefrontal cortex (Brodmann Area 10 [BA10]) activities of adolescents during the Rorschach (1921), the Rosenzweig Picture-Frustration Study (PFS; Hayashi, 1964), and Thematic Apperception Test (TAT; Murray, 1943). BA10 showed that the PFS was left-hemisphere dominant and significantly different from the Rorschach and TAT, which showed a tendency to be right-hemisphere dominant. We believe that this tendency reflects emotion and sociality.     

The relationship between attachment, personality and antisocial tendencies in a prison sample: a pilot study

This study examined the role of adult attachment and personality in relation to antisocial tendencies (i.e. convictions for violence and interpersonal problems in romantic relationships) in Norwegian prison inmates (N=92). Attachment styles and personality were measured using self-report questionnaires (RSQ; Griffin & Bartholomew, 1994; and NEO-FFI, Costa & McCrae, 1992a). The prison inmates scored higher on avoidant than on anxious attachment style. While age and agreeableness (negatively associated) emerged as significant predictors of violence, anxious attachment explained most of the variances in aggression in intimate relationships. The study suggests that different types of antisocial tendencies could have different attachment and general personality correlates.     

Internal consistency of tests: Analyses old and new

A coefficient derived from communalities of test parts has been proposed as greatest lower bound to Guttman's immediate retest reliability. The communalities have at times been calculated from covariances between itemsets, which tends to underestimate appreciably. When items are experimentally independent, a consistent estimate of the greatest defensible internal-consistency coefficient is obtained by factoring item covariances. In samples of modest size, this analysis capitalizes on chance; an estimate subject to less upward bias is suggested. For estimating alternate-forms reliability, communality-based coefficients are less appropriate than stratified alpha.I thank Edward Haertel for comments and suggestions, and Andrew Comrey for data.     

Continuity and change: assortative marriage and the consistency of personality in adulthood

How is personality stability possible amid the myriad of social changes and transformations that characterize a human life? We argue that by choosing situations that are compatible with their dispositions and by affiliating with similar others, individuals may set in motion processes of social interchange that sustain their dispositions across time and circumstance. To test this proposition we examined mate selection, using data on married couples from two ongoing longitudinal studies at the Institute of Human Development, University of California, Berkeley. Consistent with other research, the results point to homogamy as a basic norm in marriage. More important, the results show that marriage to a similar other promotes consistency in the intraindividual organization of personality attributes across middle adulthood. We offer some speculations for a more relational approach to the problem of individual continuity and change.     

Response patterns to central auditory tests and the clinical evaluation of Language Fundamentals--Revised: a pilot study.

Tests of central auditory function and measures of receptive and expressive language abilities were administered to 10 children suspected of having central auditory processing disorders. Eight of the 10 subjects displayed expressive language difficulties, suggesting a need to examine more closely the relationship between expressive language and central auditory processing.     

The consistency of presented personality: Additional evidence from aggregation

The present study investigated people's variability across situations by getting ratings of 66 subjects on 14 bipolar dimensions from at least eight interactants, chosen for their diversity. The intercorrelation of single ratings yielded a mean coefficient of .221. The correlation of single ratings with the aggregate of the other ratings for a dimension resulted in a mean coefficient of .388. The correlation of two sets of aggregated ratings gave a mean coefficient of .550, or .710 with application of the Spearman-Brown correction. Finally, computation of Cronbach's alpha gave a mean coefficient of .735. The results provide a further demonstration of the coherence that can be revealed by aggregation. Correlations of aggregated ratings on each of the 14 dimensions with extraversion ranged up to .668, and correlations with neuroticism ranged up to .410. The study suggests that there is a dispositionality in the characteristics people display, and that the emphasis on variability (e.g., Mischel, 1968; Mischel & Peake, 1982) should be tempered.     

A diet and exercise regimen: its effect upon mental acuity and personality, a pilot study.

Of the 75 patients in the February 1977 "class" at the Longevity Research Institute, Santa Barbara, California, 11 volunteers were pre- and posttested (21- to 23-day intervals) with the MMPI, 13 with the California Psychological Inventory, and 17 with four subtests of the WAIS (total: 21 males, 10 females). Ten of the (total) 32 scales showed changes in the predicted, favorable direction, statistically significant at the .05 level or better by t test. Further the number of scales changing in the predicted, desirable direction for each of the three tests was statistically significant at the .06, and .001, and .06 levels (sign test), respectively. The pilot results indicate improvement in psychological factors and mental acuity within a month's time concomitant with the diet, activity, and educational program and warrant further investigation.     

Avoidant personality disorder and implicit schema-congruent information processing bias: a pilot study with a pragmatic inference task.

Cognitive theory of personality disorders hypothesizes that each personality disorder is characterized by typical maladaptive schemes and that these schemas direct the processing of information resulting in schema-congruent biases. With regard to the avoidant personality disorder, these hypotheses were put to an initial test in a pilot study, using a self-report questionnaire to asses DSM-III-R personality pathology, a belief questionnaire to assess avoidant schemas and a pragmatic inference task to assess schema-congruent implicit attributional bias. Participants were students (n = 57) who scored high or low on DSM-III-R avoidant personality pathology. As predicted from cognitive theory, DSM-III-R avoidant personality pathology was associated with avoidant beliefs (t(45.1) = 4.68, p < 0.001) and avoidant beliefs were associated with schema-congruent information processing bias (t(55) = 2.17, p = 0.02, one-tailed test). However, DSM-III-R avoidant personality pathology was not associated with schema-congruent information processing bias (t(55) = 0.17, p = 0.43, one-tailed test). In addition to avoidant beliefs, low self-esteem was also related to the information processing bias. Social phobia and general personality pathology, two other control variables, were not. The findings warrant further study using the pragmatic inference task in a clinical group.     

Comparing personality scales across time: an illustrative study of validity and consistency in life-span archival data

The goals of this study were: (a) to examine whether personality scales, meaningful in contemporary terms, could be derived from archival data; and (b) to use these scales to aid our understanding of the relation of personality to mortality. NEO PI-R data and a battery of archival items, taken from Terman's Life Cycle Study, were collected on two new samples (sample 1 mean age = 11.9, n = 167; sample 2 mean age = 22.2, n = 203). Measurement invariance of the archival scales was assessed, and validity was examined using both rational analyses and associations with the Five Factor Model. It was demonstrated that interpretable scales can be derived from 50- to 70-year-old archival data. The archival adult personality data were then used to predict mortality. Conscientiousness remains the strongest personality predictor of longevity. Criteria for establishing the validity of archivally derived scales are suggested.     

Interpersonal perception and pathological personality features: consistency across peer groups

This study investigated the consistency of interpersonal perceptions regarding people who exhibit features of personality disorders. The participants (N=82) were college students who were assessed for features of personality disorders, using both self-report and peer nominations at Time 1. Two years later, participants attended four meetings in groups of 7 to 12 people for a total of 2 hours. Group discussions were designed to encourage interaction and give participants an opportunity to behave in ways that might be expected from people with personality problems. After Meetings 1 and 4, group members ranked their impressions of each other with regard to several personality traits and behavioral attributes. We observed important consistencies between the peer nominations collected at Time 1 and personality rankings made by a different peer group at Time 2. There was considerable convergence between personality disorder features and negative evaluations by others, with participants high in detachment eliciting the most negative reactions from peers in the lab.
