Personality differences in hindsight bias

Ten personality correlates of hindsight bias were tested in a study with 75 participants answering almanac-type knowledge questions. Participants showed hindsight bias when hindsight estimates were compared to foresight estimates (memory condition), when hindsight estimates were compared to foresight estimates of other participants (BS = between-subjects hypothetical condition), and when hindsight estimates were compared to foresight estimates in response to equally difficult control items (WS = within-subject hypothetical condition). The magnitude of hindsight bias in both hypothetical conditions was positively associated with the participant's field dependence and his or her tendency for favourable self-presentation (as measured by social desirability and impression management). Between-subjects hypothetical hindsight was associated with the participant's conscientiousness and need for predictability and control (as measured by a rigidity scale). In a multiple regression analysis, 39% of the variance in BS hypothetical hindsight, 24% of the variance in WS hypothetical hindsight, but no significant proportion of the variance in memory hindsight could be accounted for by personality measures. It is concluded that individual differences in hindsight bias exist and must be taken into account in a complete model of the effect.

Personality characteristics of ski instructors and predicting teacher effectiveness using the PRF

Normative data for the Personality Research Form (PRF) were collected from 118 ski instructors (40 female, 78 male). Subjects differed significantly from PRF norms on 17 scales (.0001 < or = p < or = .05), thus reiterating the need for caution when applying college-normed summary statistics to non-college populations. The efficacy of PRF scales as predictors of teaching effectiveness was also investigated. Three PRF scales (Abasement, Succorance and Sentience) were negatively correlated with increasing levels of teaching effectiveness. Univariate regressions yielded Abasement and Sentience scores as significant predictors of effective ski instruction.     

Personality differences among female student teachers of relatively high and low mental ability.

30 Ss scoring between 125 and 139 and 30 (out of 100) from 79 to 112 on the California Short-form Test of Mental Maturity were significantly different on the 16 PF only on Factors B and H (p = .05) and not on the California F scale. Significant comparisons appeared to be chance effects.     

Personality and American state differences in obesity prevalence

The study was conducted to determine whether state obesity-prevalence rates can be predicted by state differences in residents' levels on the Big Five personality variables (O. P. John & S. Srivastava, 1999). State obesity prevalence was the mean percentage of the state population from 2000 to 2005 with a body mass index > or = 30.0 as assessed by the Behavioral Risk Factor Surveillance System (Centers for Disease Control and Prevention, 2010), which currently interviews more than 350,000 adults annually. State neuroticism, extraversion, agreeableness, conscientiousness, and openness z scores, based on the responses of 619,397 residents to an Internet survey from 1999 to 2005, were taken from P. J. Rentfrow, S. D. Gosling, and J. Potter (2008). Alaska, Hawaii, and North Dakota had scores outside -3 and +3 standard deviations on at least 1 variable and were excluded as outliers. For the 47 remaining states, state obesity prevalence was significantly correlated with neuroticism (.35), agreeableness (.38), openness (-.44), socioeconomic status (-.74), white percentage (-.34), and urbanization (-.43). Multiple regression analysis showed that socioeconomic status could account for 54.0% of the criterion variance and that agreeableness, neuroticism, and openness together could account for another 17.1%.     

Personality differences among child molesters.

This study compared the MMPI profiles of two groups of child molesters, those with no prior arrests versus those with one or more prior arrests, in order to assess certain clinically derived inferences about these offenders. The sample consisted of 33 persons convicted of child molestation. The group with prior arrests showed more psychopathology than the group with no previous arrests.     

Personality and executive functioning as risk factors in recidivists

The classification of an inmate population at a maximum security jail in Canada was undertaken to study factors correlated with recidivism. A total of 12 recidivists and 12 nonrecidivists were classified according to their index offenses, and a Criminal Record search was completed to verify their statements. A total of 15 non-offenders who had also undergone a criminal record check were included as controls. All participants were administered the Minnesota Multiphasic Personality Inventory-168, Violence Risk Scale-Experimental Version, Coopersmith Self-esteem Inventory, and the Wisconsin Card Sorting Task. Statistical analysis showed significant differences between the groups on scores for the Hypochondriasis, Psychopathic Deviate, and Hypomania scales of the MMPI-168. Significant differences were noted for the Wisconsin Card Sorting Task and the Violence Risk Scale. Discriminant analysis of the recidivists and nonrecidivists correctly classified at a 91.3% level.     

Personality patterns of suicide attempters: gender differences in Ukraine

In the present study, an attempt has been made to investigate the complete 'pattern' of a suicide attempter (SA) within the set of Big Five traits. Two models were used: M1, which includes the five main dimensions of Big Five in the analysis; and M2, which includes facets of those dimensions which were identified as important in M1. The study consisted of a group of SA (men - 326, women - 299) and a group of healthy volunteers (HV) (men - 143, women - 190) with a similar age range. Discriminant analysis (DA) showed that the factors most significant in discriminating the personality pattern of a male SA are (in decreasing order): (E) Extraversion, (N) Neuroticism, (C) Conscientiousness and (O) Openness; and for a female SA these factors were (E) Extraversion, (C) Conscientiousness and (A) Agreeableness. In M2 for men, the largest contribution to pattern recognition is (N3) Depression. Moreover, in M2 for men significant characteristics were (in descending order): (E6) Positive Emotions, (O1) Fantasy, (E4) Activity, and also (N2) Angry Hostility, (C3) Dutifulness, (C4) Achievement Striving, (C2) Order and (O6) Values; and for women: (E4) Activity, (C6) Deliberation, (C2) Order, (A6) Tender-Mindedness, (E5) Excitement Seeking, (E6) Positive Emotions, (C4) Achievement Striving, (A2) Straightforwardness, (C5) Self-Discipline and (E1) Warmth. Analysis of the obtained data demonstrates that suicide attempts amongst males, can largely be associated with personality variables reflecting negative emotions; while female suicide attempts are primarily associated with variables regarding activity and self-regulation.     

Personality and the genetic risk for alcohol dependence

The extent to which the genetic risk for alcohol dependence (AD) and conduct disorder (CD) and their common genetic risk overlap with genetic factors contributing to variation in dimensions of personality was examined in a study of 6,453 individuals from 3,383 adult male and female same-sex and unlike-sex twin pairs from the Australian Twin Registry. The associations between the personality dimensions of positive emotionality, negative emotionality, and AD and CD risk were modest, whereas the associations between behavioral undercontrol and AD and CD risk were substantially higher. Genetic influences contributing to variation in behavioral undercontrol accounted for about 40% of the genetic variation in AD and CD risk and about 90% of the common genetic risk for AD and CD. These results suggest that genetic factors contributing to variation in dimensions of personality, particularly behavioral undercontrol, account for a substantial proportion of the genetic diathesis for AD and most of the common genetic diathesis for AD and CD among both men and women.     

Sex differences in risk taking and its attribution

In the original Kogan-Wallach Choice Dilemmas Questionnaire (CDQ), an oftused measure of risk-taking disposition, the central character in the majority of items is male. For this study, a revised 10-item CDQ was constructed with content appropriate for both sexes. Two forms were employed, identical in all respects except for the use of a male or female name to identify the central protagonist in each CDQ item. When the two forms were administered to male and female undergraduates, the female form elicited somewhat higher levels of risk taking. This effect was especially pronounced in the male subjects. When asked to specify how their peers would respond to each of the CDQ items, subjects attributed greater caution to female than to male peers relative to their own preferred risk level. The outcomes suggest that subjects (especially males) find highly achieving women in the CDQ items more exceptional than their male counterparts, and hence able to tolerate more risk. In striking contrast, subjects' female peers are considered a rather cautious lot.The present research was formulated in the course of discussions with Marvin Frankel. The authors are enormously grateful for his help and would also like to thank Kathleen Connor and Joel Kostin for their aid in statistical and computer analyses. An earlier version of of this article was presented as a paper at the annual convention of the American Psychological Association, Chicago, 1975. The article was completed during the period (1976–1977) that the senior author was a Visiting Scholar in the Department of Psychology, University of California, Berkeley.     

Personality differences between established and less-established male and female creative artists

Past research on personality constructs of creative individuals has focused on men rather than women and has neglected the essentially social aspect of being considered creative. Therefore, personality variables of 60 male and 60 female creative artists were described using the California Psychological Inventory (CPI). Male and female groups were further divided equally into two subgroups reflecting a difference in degree of social acceptance of their work. Relationships between the four groups were explored by multiple discriminant analysis. The major conclusion noted was that creative females tend to be more like their creative male counterparts, in terms of CPI scale variation, than are males and females in general.     

Individual differences and risk taking in rock climbing

ObjectivesThe primary objective of the study was to challenge the notion that risk taking populations are homogenous, and that risk taking in sport necessarily reflects the expression of trait sensation seeking. A secondary objective was to examine the potential role of additional individual differences, such as self-efficacy and impulsivity, which have traditionally received limited attention.DesignQuantitative cross-sectional study.MethodsOne hundred and sixteen active rock climbers completed the Impulsive-Sensation Seeking Scale, a domain-specific self-efficacy scale, and behavioral measures of ability, experience and risk taking in rock climbing.ResultsThose high in self-efficacy and male climbers were likely to take greater risks; small associations with age, sensation seeking and impulsivity were also observed, though these were not in the hypothesized direction and failed to predict unique variance in regression analyses.ConclusionsTo challenge themselves, rock climbers may take calculated additional risks when they feel confident in their ability to manage those risks. Researchers should not assume homogeneity within risk taking populations, or that people take risks in all domains due to elevated sensation seeking needs.
