Biochemical correlates of personality traits in normals: An exploratory study

This study attempted to identify biochemical systems associated with the personality dimensions of Extraversion (E), Neuroticism (N), Psychoticism (P), Sensation Seeking (SS) and Impulsivity (Imp). The subjects were 43 normal volunteers who volunteered to take a battery of psychological tests and allow investigators to obtain samples of blood, urine and cerebrospinal fluid (CSF) for biochemical assessment.Substantial positive correlations were found between CSF norepinephrine (NE), MHPG (the principal metabolite of NE), DBH (an enzyme involved in the production of NE) and plasma MHPG and DBH; all of these are regarded, in some part, as putative indicators of central noradrenergic activity. After partialling out the influences of age, height and weight, a number of significant relationships were found between psychological traits and biochemical variables. Extraversion correlated positively and introversion and neuroticism correlated negatively with CSF Ca. Neuroticism also correlated negatively with plasma MHPG. Ego Strength (inversely related to Neurotic Introversion), P and Disinhibitory SS correlated negatively with CSF cort. General SS correlated negatively with CSF NE and plasma DBH, and these correlations were significant in both males and females, as well as in the total group. The results are consistent with some biological models of personality, but suggest the need for modification in others.     

An investigation of worry and sense of humor

To investigate the relationship between worry and sense of humor, the author administered the Worry Domains Questionnaire (WDQ; F. Tallis, M. Eysenck, & A. Matthews, 1992) and the Multidimensional Sense of Humor Scale (MSHS; J. A. Thorson & F. C. Powell, 1993) to 140 undergraduates. Worry was negatively related to sense of humor. Results of a stepwise regression, using the WDQ as the criterion and the MSHS factors as predictors, showed that the humor production factor of the MSHS loaded negatively on Step 1 and the coping with humor factor loaded positively on Step 2. The results are discussed in relation to W. E. Kelly and M. J. Miller's (1999) cognitive model of worry and worry as a coping strategy.     

Undertakers' sense of humor.

A group of 60 middle-aged morticians at a professional seminar in the midwestern USA who completed a multidimensional sense of humor scale scored significantly lower than another group of 136 men from other occupations. The difference between the two groups appeared almost entirely on scale items having to do with humor generation or creativity.     

A theory of sense of humor

Abstract.— Humor is a strategem for relating the collective social reality of a group of persons (the rational world) to their personal imaginations of alternative social worlds, meanings, or identities (the irrational world). The humorist is committed to the rational world. At the same time he permits idiosyncratic phantasies to occur within the social context if they are accompanied by an explicit message saying that the performance is made for fun. By such communications the rational social world is kept stable as well as more tolerable. The comical situation is composed of three essential elements: (1) the message, (2) the audience, and (3) the target or content treated by the message. The message brings the target to the irrational level, where it is brought into disrespect in favor of the alliance between the humorist and his audience. Laughter is the announcement that the disrespect is accepted just for fun. A person may, however, keep a straight face for different reasons. A conceptual scheme is proposed for prediction of laughter. It is based upon three dimensions of the comic situation: (1) the humorous message, (2) the interpersonal likings, and (3) the permissiveness towards actual laughter. The corresponding personal dispositions are the habitual sensitivity to such messages, the habitual tendency to favor comical situations and persons, and the habitual need for emotional-impulse control. Suggestions are made as to the modification of laughter by constellations of high and low values on these variables.     

Feminism and women's sense of humor

The present study empirically examined the long-standing folk belief that women, especially feminist women, have no sense of humor. Svebak's (1974) revised Sense of Humor Questionnaire [SHQ; (1974b) “Revised Questionnaire on the Sense of Humor,” Scandinavian Journal of Psychology, Vol. 15, pp. 328–331], the short version of the Attitudes Toward Women Scale [ATW; found in J. T. Spence and R. L. Helmreich (1978) Masculinity and Femininity: Their Psychological Dimensions, Correlates, and Antecedents, Austin: University of Texas Press], and S. K. Murnen and D. Byrne's Hyperfemininity Scale [HF; (1991) “Hyperfemininity: Measurement and Initial Validation of the Construct,” The Journal of Sex Research, Vol. 28, pp. 479–489] were administered to 175 college women. Self-ratings were also obtained of the women's stands on women's issues (from traditional to feminist), their own sense of humor, and how often other people typically laugh at their humor. Significant positive correlations occurred between the latter two measures and Svebak's scale. A significant negative correlation appeared between the ATW and the HF. The lack of a significant association between the women's self-rated sense of humor or the SHQ and either the ATW or HF suggests that no relationship between feminism and sense of humor was demonstrable at least with these instruments in this young adult sample.     

The general factor of personality and humor styles

The present study examined the phenotypic, genetic, and environmental correlations between a general factor of personality (GFP) and four humor styles: affiliative, self-enhancing, aggressive, and self-defeating. Participants were 571 same-sex adult twin pairs. Individuals completed the Humor Styles Questionnaire (HSQ) and a short form of the NEO personality scale (from which the GFP was extracted). The GFP was found to be heritable with an estimated value of .31. At the phenotypic level, the GFP was found to correlate significantly with the HSQ scales; positively with affiliative and self-enhancing, and negatively with aggressive and self-defeating. Three of the four phenotypic correlations were found to be attributable to correlated genetic factors, suggesting that these dimensions of humor styles and the GFP may have a common genetic factor.     

Multicultural personality dispositions and trait emotional intelligence: an exploratory study

This study examined the relationship between multicultural personality dispositions and trait emotional intelligence. The sample included 152 graduate education students enrolled at a university in a large northeastern city of the United States. The multicultural personality dispositions of Cultural Empathy and Social Initiative predicted variance in trait emotional intelligence above and beyond the variance accounted for by gender and potential socially desirable responding. Study limitations are highlighted, and suggestions for follow-up quantitative and qualitative research are presented.     

Revised questionnaire on the sense of humor

Abstract.— A Sense-of-Humor Questionnaire (SHQ), based on the proposed 3–dimensional theory of sense of humor, was given to male and female students in social and physical sciences to test its construct validity. There were positive and significant correlations between the laughter-activating dimension (M_p) and each of the two laughter-inhibiting dimensions (L_p, and E_p), the latter being zero correlated with each other. In a two-way analysis of variance (sex X science), the main effects were a sex difference on the L_p- as well as E_p-dimension, while no main effect was found on the M_p-dimension. The L_p-scores discriminated between men and women in the social sciences, and the E_p-scores in the physical sciences. All results are in agreement with theory.     

Pathological gambling and personality disorders: an exploratory study with the IPDE

This article describes the most frequent personality disorders related to pathological gambling. Participants included 50 pathological gamblers assessed with the IPDE, and 50 normative subjects from the general population with the same demographic features (age, sex, and socioeconomic level). Thirty-two percent of the clinical sample (vs. the 8% of the normative sample) showed at least one personality disorder. The most prevalent disorders were Borderline (16%), followed by Antisocial, Paranoid, Narcissistic, and Non-specified (8% each). Gamblers with personality disorders presented an average of 1.5 disorders and they reported higher gambling severity and more severe symptoms of anxiety, depression and alcohol abuse. The implications of this study for clinical practice and research are discussed.     

Men's sense of humor and women's responses to courtship solicitations: an experimental field study

Producing humor might function as a fitness indicator associated with greater desirability during dating selection. A male confederate in a bar was instructed to tell (or not tell) funny jokes to two other male confederates. A few minutes later, when the second of two male confederates left, the first male confederate asked a female who was near his table and who had heard the funny jokes for her phone number. The previous expression of humor was associated with greater compliance with the male confederate's request and with a higher positive evaluation. The possible effects of humor are discussed from an evolutionary perspective.     

The location of superfactors P, E and N within an unexplored personality factor space

Two questionnaires designed by Howarth (HPQ, APF2) whose factor space in unexplored and the EPQ (Eysenck) were jointly scale factored on 79 subjects, under the hypothesis that Eysenck's superfactors of P, E, and N should be represented as major influences in the resultant factor structure. A prinicipal component analysis yielded 7 factors from 24 by the Kaiser-Guttman and Scree Test, these 7 being rotated to a maximum simple structure by the Direct Oblimin procedure. Although failing to satisfy Bargmann's test of simple structure, this solution was accepted as adequate, noting the deficiencies og Bargmann's test and the efficiencies of the rotation method used. Within the 7 factor solution, P, E, and N were seen to be located as factor numbers 2, 3 and 1, respectively. One interesting detail is that a sociability primary loaded with an impulsivity primary on the Extraversion factor contrary to Guilford's (1977) arguments for the independence of these primaries. It is concluded that Eysenck's assertion of the enduring stability and breadth of the PEN factor triad has been upheld.     

Note on Thorson and Powell: undertakers' sense of humor

Recently Thorson and Powell reported in this journal that morticians scored significantly lower on a multidimensional sense of humor scale than another group of similarly aged men from other occupations. These findings differ markedly with some in 1991 from a 2-yr. ethnographic study conducted with morticians and funeral directors in four states regarding how they managed the stigma associated with their occupation.     

Perceptions of the utility of personality assessment for personnel selection in the South African context: An exploratory study

This study explored South African industrial psychologists’ perceptions of the utility of personality assessment for personnel selection. Eleven industrial psychologists (2 male, 9 female) from the Johannesburg area, South Africa were the participants. They participated in semi-structured interviews exploring their understanding of the place of personality assessment in personnel selection within organisational settings in South Africa and the common practices employed. Thematic analysis was used to analyse the data. Four dominant themes emerged from the data: person-environment fit; specific uses of personality tests; commonly used tests and validity and ethical concerns. Based on the findings, personality assessment use in South African industry settings appears multi-layered and consistently evolving.     

Setting the sales budget: An exploratory study

This article explores how the sales budget is set in a business organization. Findings from a longitudinal participant observation study revealed that the sales budget is considered of great importance to the organization as sales estimates serve as premises for planning of production and supply and new product developments. It was observed that the sales budget was based on a narrow, inner-directed perspective, almost looking away from important environmental driving forces such as competitors and customers. The findings also showed that individuals involved in the sales budgeting process behaved opportunistically, influencing the budgetary process and outcomes. Theoretical and normative implications are highlighted.     

Continuously varying binocular disparity: An exploratory study

It was hypothesized that viewing an object under conditions of continually varying binocular disparity would result in the perception of a “real” object that would continually change its shape, yet retain its three-dimensionality. It was further hypothesized that observed changes would be systematically sequential and repetitive, reflecting systematic and repetitive changes in the stimulus conditions. Two Ss were used. They were shown 12 objects (one at a time) by means of the Groman Continuous Binocular Disparator. An analysis was made from taped verbal reports. The hypotheses were strongly supported. Other phenomena were noted and described. The observations were categorized on the basis of three types of breakdown of veridicality. Differences between the frequency of breakdown of veridicality in the three categories were found and discussed in terms of a functional theory of veridical perception.     

Meditation and psychosocial adaptation: An exploratory study

The current study examined differential patterns of interrelationships between meditators and nonmeditators on issues pertaining to psychosocial adaptation. Subjects (N=66) were randomly selected from mailing lists provided by theAssociation of Transpersonal Psychology or were solicited via classified advertising in theChicago Tribune and theDallas Morning News. The findings of the current study indicate that there are no differences between meditators and nonmeditators on level of psychosocial adaptation. However examination of the zero-order correlations between dependent measures revealed differential patterns of interrelationships within the meditator and nonmeditator groups. The findings suggest that further research is needed which expands upon the influence of meditation on psychosocial adaptation by addressing topics specific to meditative practice. The implications for the development of qualitative research methods designed to investigate psychosocial parameters in transpersonal psychology are discussed.
