Paranormal Beliefs and the Barnum Effect

The acceptance phenomenon (i.e., the general tendency for persons to accept almost any bogus personality feedback; Layne, 1979) may be related to certain paranormal beliefs (Alcock, 1981; Hyman, 1981). Paranormal beliefs are beliefs in phenomena that, if authentic, violate basic limiting principles of science (Broad, 1953; Tobacyk & Milford, 1983). One specific illustration of the acceptance phenomenon is the "Barnum effect," which refers to acceptance of bogus personality feedback consisting of relatively trivial statements with a high base rate (Layne, 1979; Snyder, Shenkel, & Lowery, 1977). The Barnum effect has been implicated in personal validation and in "cold reading," both of which are used routinely by many astrologers, clairvoyants, faith healers, fortune tellers, graphologists, mediums, Tarot Card readers, and others (Hyman, 1981). It was hypothesized that paranormal beliefs emphasizing divinatory procedures that produce personalized feedback (i.e., precognition, spiritualism, superstition, and witchcraft) are associated with greater susceptibility to the Barnum effect.     

Accepting personality test feedback: A review of the Barnum effect

This article attempts a comprehensive and critical review of the by-now fairly extensive literature on the Barnum effect—the approval/acceptance by subjects of bogus personality interpretations supposedly derived from standard tests. Since the last major review eight years ago various methodological extensions have occurred and various rival hypotheses for established findings have been proposed. The present review is divided into three major sections: client and clinician characteristics; feedback statements and test format; and implications for personality assessment and measurement. Nearly 50 studies on the acceptance of personality interpretations are systematically reviewed and criticized.     

The interactive effect of neuroticism and extraversion on the daily variability of affective states

The interaction between neuroticism and extraversion is thought to predict affective variability. In this study, neuroticism and extraversion were assessed with questionnaires, and affects were measured by experience sampling, with five daily assessments over 2 weeks. Affective variability was studied within a three-dimensional affective space whose three axes were oriented along the main affective dimensions: positive affect, negative affect, and activation. Quantile regression mixed-effects models allowed predicting zones in which affective states were most likely to occur according to personality. Beyond the well-known effect of personality on affect level, high neuroticism and/or high extraversion were accompanied by heightened affective variability. Results were interpreted as potentially reflecting positive feedback loops oriented toward negative affect for neuroticism, and toward positive affect and activation for extraversion.     

The Barnum effect in a group setting

The present study expands the typical Barnum effect paradigm by investigating reactions to feedback in a group setting. People initially participated in a group experience (8 per group), and then were given bogus positive or negative feedback (the favorability manipulation) purportedly prepared by either the group leader or another group member (the source status manipulation). The answerability manipulation led participants to believe that they either would or would not have to share their reactions to the feedback with the person who prepared it. Positive feedback was rated as more accurate and accepted more highly than the negative feedback, though no differences in recall of either the positive or negative feedback emerged. Additionally, a pattern of results revealed that the feedback from the group leader generated greater perceived accuracy, acceptance, and recall than did feedback from another group member. Implications for the impact of feedback given by a high status person in group settings are discussed.     

神经质和外倾的负情绪减弱调节特点

神经质和外倾一致被认为是有典型情绪风格的人格特质,人格生物机制研究发现,这两种特质在神经递质、脑机制及遗传等方面都具有其特定的机制。可是,关于这两种特质在情绪调节过程的生理心理机制研究还比较少。这项研究试图寻找高神经质和高外倾人群在负情绪调节过程中,包括情绪主观报告、表情行为及生理反应等方面的变化特点。研究采用生理心理实验法比较了高神经质和高外倾被试在使用认知重评、表情抑制减弱由录像片段诱发的负情绪（厌恶）时所引起情绪成分的实际变化结果。28名高神经质和28名高外倾大学生被试参加了实验。结果表明：与高外倾组比较,高神经质组在情绪激活及调节之前阶段（指导语阶段）的FPV增幅较大,在情绪被激活及调节阶段（正片阶段）的R-R间期增幅较小,整个调节过程报告较多的负情绪（如痛苦）变化。研究从生理心理层面进一步地说明,与高外倾比较,高神经质确实更容易激活其负情绪,而且,更难以对其负情绪实施减弱调节     

Reliving emotional personal memories: affective biases linked to personality and sex-related differences

Although available evidence suggests that the emotional valence and recollective properties of autobiographical memories (AMs) may be influenced by personality- and sex-related differences, overall these relationships remain poorly understood. The present study investigated these issues by comparing the effect of general personality traits (extraversion and neuroticism) and specific traits linked to emotion regulation (ER) strategies (reappraisal and suppression) on the retrieval of emotional AMs and on the associated postretrieval emotional states, in men and women. First, extraversion predicted recollection of positive AMs in both men and women, whereas neuroticism predicted the proportion of negative AMs in men and the frequency of rehearsing negative AMs in women. Second, reappraisal predicted positive AMs in men, and suppression predicted negative AMs in women. Third, while reliving of positive memories had an overall indirect effect on postretrieval positive mood through extraversion, reliving of negative AMs had a direct effect on postretrieval negative mood, which was linked to inefficient engagement of suppression in women. Our findings suggest that personality traits associated with positive affect predict recollection of positive AMs and maintenance of a positive mood, whereas personality traits associated with negative affect, along with differential engagement of habitual ER strategies in men and women, predict sex-related differences in the recollection and experiencing of negative AMs. These findings provide insight into the factors that influence affective biases in reliving AMs, and into their possible link to sex-related differences in the susceptibility to affective disorders.     

外倾个体何以有更多正性情绪体验？——情绪调节自我效能感的中介作用

通过对1076名大学生进行人格特质(外倾和神经质)、情绪调节自我效能感和情绪体验的测查,本研究探讨了外倾和神经质影响情绪的可能机制。结果表明：(1) 情绪调节自我效能感与外倾和神经质之间有紧密联系;(2) 外倾与情绪调节自我效能感可以有效预测个体正性情绪的变异;(3) 外倾对正性情绪的影响部分是以情绪调节自我效能感为中介的。该发现对实践中提升个体情绪调节自我效能感、改善情绪状态并最终优化人格结构具有重要启示。     

Child’s Personality and Perception of Parental Relationship as Correlates of Optimal Experience

The study was designed to assess the influence of child’s personality and perception of parental relationship on children’s optimal experiences. We proposed functional and dysfunctional models to analyze the increase or the decrease of the children’s flow experience. The sample of this study included 909 middle class children, aged 9–12 (M = 11.02, SD = 1.08), both sexes, from Argentina. When we analysed the psychological factors that could be related to the flow state in childhood, we found out that the child’s perception of a functional parental relationship, in which there is either acceptance or moderate control, indirectly affects the flow experience, through child’s personality—extraversion, openness to experience, and conscientiousness. Functional personality traits have an important positive effect on optimal experience when they are considered as a unit. In the dysfunctional model of flow, the results showed that the child’s perception of parental pathological control had an important positive effect on neuroticism and –through this—a negative effect on flow. The child’s perception of parental negligence did not have a significant effect on neuroticism; however, neuroticism still maintained its negative effect on flow.     

Personality moderates the interaction between positive and negative daily events predicting negative affect and stress

A 30-day diary study examined personality moderators (neuroticism and extraversion) of the interaction between positive and negative daily events predicting daily negative affect and night-time stress. Multilevel analyses revealed positive daily events buffered the effect of negative daily events on negative affect for individuals low in neuroticism and individuals high in extraversion, but not for individuals high in neuroticism or individuals low in extraversion. Positive daily events also buffered the effect of negative daily events on that night’s stress, but only for participants low in neuroticism. As such, this research linked today’s events to tonight’s stressfulness. This study advances our understanding of how neuroticism and extraversion influence within-person associations between positive and negative events predicting negative affect and stress.     

Mobility,extraversion, and neuroticism

Mobility, a property of Pavlovian higher nervous activity, was measured using an induction task. Negative induction, following presentation of an excitatory stimulus, is an index of mobility of excitation and positive induction, following presentation of an inhibitory stimulus is an index of mobility of inhibition. Mobility scores from 27 male and 37 female first-year psychology students, age 17 to 42 years were related to extraversion and neuroticism derived from Eysenck’s Personality Inventory (Form A). Mobility of excitation and mobility of inhibition were found to be unrelated. Individual differences in the magnitude and latency of induction indicate that individuals can be typed according to low, medium, or high mobility of either nervous process. No relationship was found between neuroticism and mobility, and no relationship was found between extraversion and mobility of excitation. However, a significant negative relationship was found between extraversion and mobility of inhibition, providing a link between Pavlovian properties of the nervous system and Eysenck’s personality dimension of extraversion.     

Neuroticism and extraversion as mediators between positive/negative life events and resilience

Positive and negative life events have been demonstrated to play an important role regarding the development of resilience. However, it is less clear how life events interact with personality factors in forming individual resilience. Thus, the present study investigates the mediating effects of the two main complementary personality dimensions extraversion and neuroticism on the relationship between life events and resilience in adulthood. Traumatic Antecedent Questionnaire (TAQ), NEO-Five-Factor Inventory (NEO-FFI) and Connor–Davidson Resilience Scale (CD-RISC) were administered to 201 healthy subjects. Results from path analyses (AMOS) revealed that the personality factors neuroticism and extraversion (measured by NEO-FFI) fully mediated the association between positive life events and resilience. This is the first study to date using psychometric assessment to explore the possible pathways from positive/negative life experiences to resilience.     

Personality traits modulate skin conductance response to emotional pictures: An investigation with Cloninger’s model of personality

Several studies found strong relationships between main personality dimensions and emotions, and more particularly between neuroticism and negative emotions, as well as between extraversion and positive ones. In these studies, personality was mainly assessed with respect to the big five model, and emotions were evaluated with subjective rating scales. To extend the exploration of the associations between personality and emotion, the aim of the present study was to investigate the relationships between Cloninger’s dimensions of personality and emotional reactivity assessed by skin conductance response (SCR). In 55 normal subjects, SCR was recorded while they were presented pictures selected as positive, negative and neutral from the International Affective Picture System. The results showed no influence of personality on response magnitude, but subjects with higher harm avoidance scores showed longer half-recovery times for negative relative to neutral pictures. This result is consistent with the dispositional bias of harm avoidance to respond intensely to signals of aversive stimuli.     

Some personality correlates of self-rated academic success.

Using subjects' own ratings of their academic performance, a group of american university students were divided into academically successful (n = 312) and unsuccessful (n = 170) subgroups. A comparison of mean scores of the two groups on nine personality variables convered by Eysenck's PEN Inventory and Lanyon's Psychological Screening Inventory showed that academic success, as rated by subjects themselves, is associated with low psychoticism, neuroticism, and discomfort but high extraversion and defensiveness.     

A behavior genetic analysis of personality and loneliness

The phenotypic, genetic, and environmental correlations between the Big Five factors of personality and loneliness were examined. At the phenotypic level, loneliness had a strong significant positive correlation with neuroticism, significant moderate negative correlations with agreeableness, conscientiousness, and extraversion, and a small positive correlation with openness. Both loneliness and personality were found to be heritable. Bivariate genetic analyses resulted in significant positive genetic correlations between loneliness and neuroticism and openness, and significant negative genetic correlations with agreeableness, conscientiousness, and extraversion. Significant unique environment correlations were found between loneliness and four of the five personality factors (all negative except neuroticism) and a non-significant correlation with openness. The results suggest common genetic and unique environmental factors play a role in personality and loneliness.     

Drug tolerance and personality: Some implications for Eysenck's theory

Two previous studies, one of nitrous oxide and the other of amylobarbitone sodium, had shown that tolerance of these drugs, assessed by the ‘sedation threshold’ procedure, was influenced by an interaction between introversion-extraversion and neuroticism: tolerance was negatively correlated with E in High N subjects and positively with E in low N subjects. In a study described in the first part of this paper the same result was found for thiopentone among a group of 50 surgical patients, tested as part of their routine pre-operative procedure. The remainder of the paper is devoted to a more detailed analysis of this interactive effect, undertaken by combining the personality and sedation threshold scores from three studies. In this larger sample the previously observed results were broadly maintained, in that neurotic extraverts and normal introverts proved to have very low drug tolerance; the highest tolerance was found, however, in introverts with moderate, rather than very high, neuroticism. Comparison with similar data for a large group of neurotic patients revealed a somewhat different picture: the sedation thresholds of patients were sometimes predictable from their personality scores and sometimes from their diagnoses, the two not always coinciding. The results as a whole are discussed with reference to the possible neurophysiological mechanisms mediating depressant drug action and personality differences. Specifically it is suggested that some parts of the observed variation in drug tolerance might be explained by combining certain features of the modifications to Eysenck's theory of extraversion and neuroticism proposed, respectively, by Gray and by Claridge. However, it is considered that not all of the variation can be explained in this way and that other personality characteristics, probably those associated with ‘psychoticism’, are likely to prove important determinants of drug tolerance differences.     

Personality and accident liability: are extraversion, neuroticism and psychoticism related to traffic and occupational fatalities?

The aim of the present study was to investigate the relationship between extraversion, neuroticism and psychoticism, and road traffic fatalities in a data set of 34 nations. In addition to traffic fatalities per 100,000 vehicles, work-related fatalities were included in the study. Results showed that extraversion had a positive relation to the number of traffic fatalities whereas neuroticism correlated negatively with road fatalities. Occupational fatalities were strongly related to deaths on the roads but not to personality dimensions. Countries with high extraversion scores had more traffic fatalities than countries with moderate or low extraversion scores. The need for well-designed studies investigating the link between personality factors and traffic accident liability via driver behaviour was expressed.     

Prediction of stress appraisals from mastery,extraversion, neuroticism,and general appraisal tendencies

Several personality dimensions (mastery, extraversion, and neuroticism) and a new General Appraisal Measure were used to predict stress appraisals made by college students in specific situations. Using multiple-regression techniques, mastery and general appraisal tendencies predicted appraisals for an intellectual task. Path analysis supported a structural model with general appraisal tendencies as a mediator between mastery and specific appraisal. In the second study mastery, extraversion, neuroticism, and general appraisal tendencies predicted appraisals for an academic stressor. Path analysis again supported the mediational nature of general appraisal tendencies from personality variables to specific appraisal. We discuss a potential causal mechanism between personality dimensions and appraisal patterns.     

Lay conceptions of neuroticism

This paper is concerned with various aspects of a lay-person's conceptualization of neuroticism. Three experiments are reported which aim to investigate various determinants of the common-sense conception of neuroticism. In the first experiment subjects completed various standardized psychological tests measuring neuroticism and anxiety, while also estimating the extent of their own anxiety and neuroticism. In the second experiment subjects attempted to detect items measuring neuroticism in a standard personality questionnaire and secondly estimate the extent of their own and the ‘average’ person's neuroticism. Finally, in the third experiment subjects rated the typicality of various neurotic traits and behaviour which had been supplied by subjects in the previous two experiments. The results suggested some similarity in expert explicit theories and lay-person implicit theories, though there appeared to be systematic biases in the subjects' perception of their own neuroticism. The results are discussed in terms of the correspondence between implicit theories and explicit theories, and the functions of each theory in everyday life are considered. Problems associated with these studies and this research in general are discussed.
