Creative thinking abilities and hemispheric asymmetry in schizotypal college students

Two groups of college students that scored high (N=25) and low (N=60) on a schizotypal personality index based on the Perceptual Aberration, Magical Thinking, and Schizotypal Personality Scales, were tested for hemisphericity using a dichotic listening task and completed the Torrance Test of Creative Thinking. The schizotypy scales correlated with high scores on the nonverbal portion of the creativity tests and with a left ear preference to dichotically presented verbal stimuli. The Torrance Test of Creative Thinking did not correlate, however, with hemispheric asymmetry. These results clarify the relationship between schizotypy and creating thinking abilities but fail in establishing the role of hemispheric asymmetry in the production of creative thinking ideas. This article is based on a portion of the first author’s dissertation at Wayne State University.     

Overcoming Negative Aspects of Perfectionism through Group Treatment

The tendency to hold and pursue excessively high standards for oneself and for others can interfere with academic achievement. Counsellors who work in university settings are often presented with students whose capabilities do not reflect their levels of achievement. This study reports on the evaluation of an eight-week group intervention designed to help university students shift from negative and often debilitating perfectionism to positive and enhancing perfectionism. The group treatment focused on changing attitudes, beliefs, feelings, and interpersonal interactions affected by perfectionism using combined cognitive-behavioral and interpersonal approaches. Standardized measures, including the Beck Depression Inventory (Beck et al., BDI-II manual. San Antonio: The Psychological Corporation, 1996), the Beck Anxiety Inventory (Beck and Steer, Beck Anxiety Inventory: Manual. San Antonio: The Psychological Corporation, 1993), and the Multidimensional Perfectionism Scale (Hewitt and Flett, Journal of Personality & Social Psychology, 60, 456–470, 1991a), provided data for pre- and post analysis of a treatment group (n = 30), and comparison groups of students attending group programs on career planning (n = 30) and attending psychology classes (n = 30). Results show that students participating in the treatment group significantly reduced their levels of depression, anxiety, and perfectionism in comparison to students who did not attend the treatment program. Implications of the findings suggest the importance of considering perfectionism on a continuum of negative and positive influences while helping students to address the intrapersonal and interpersonal dimensions of perfectionism.     

Personality, motivational and situational determinants of regular and occasional use of smokeless tobacco

This study evaluated the effects of personality, motivational, and situational factors on Regular (n=191) and Occasional (n=80) users of smokeless tobacco (SLT) products. The participants completed the Eysenck Personality Questionnaire (EPQ), Spielberger’s State-Trait Personality Inventory (STPI) and Anger Expression (AX) Scale, and questionnaires designed to evaluate the reasons why SLT-Users begin, continue, and are motivated to use smokeless tobacco. Occasional Users had higher scores than Regular Users on the EPQ Extraversion scale; no other personality differences were found between these groups. Ratings of the importance of the reasons for beginning to use tobacco products were quite similar for the Regular and Occasional Users; novelty and enjoyment were ranked highest by both groups. In contrast, Regular Users rated 7 of the 10 reasons for continuing to use tobacco as significantly more important than Occasional Users; enjoyment, stimulation and management of emotions were ranked as most important by both groups. Findings that smokeless tobacco products enhanced positive affect and intellectual stimulation, and reduced anxiety and boredom were generally consistent with Eysenck’s Diathesis Stress Model.     

Language development of pre‐school children born to teenage mothers

An Erratum has been published for this article in Infant and Child Development 10(4) 2001, 241. This paper compares the language development of pre‐school children born to teenage (n=22) and comparison mothers (n=20) and examines the extent to which differences in language development can be explained by social background, child and parenting factors. Mothers and children were assessed at home using a range of measures, including a structured interview, the language scales of the Child Development Inventory, the HOME Inventory, and videotaped mother‐child interaction. Results showed that children of teenage mothers perform significantly poorer than children of comparison mothers on measures of expressive language and language comprehension. Subsequent analyses showed that these differences are largely explained by differences in the parenting behaviour of teenage and comparison mothers. Specifically, maternal verbal stimulation and intrusiveness accounted for the relationship between teenage motherhood and children's poorer language comprehension, while maternal intrusiveness and involvement with the child account for the relationship between teenage motherhood and children's poorer expressive language development. These findings highlight the importance of early mother–child interaction for children's language development. Copyright © 2001 John Wiley & Sons, Ltd.     

Perfectionism Dimensions and the Five‐factor Model of Personality

This study of university students (n = 357) and community adults (n = 223) examined personal standards (PS) and evaluative concerns (EC) higher‐order dimensions of perfectionism that underlie several measures from three different theoretical frameworks. In both students and community adults, confirmatory factor analyses supported PS perfectionism and EC perfectionism higher‐order latent factors. In relation to the revised NEO Personality Inventory, PS perfectionism was primarily related to conscientiousness and achievement striving. In contrast, EC perfectionism was primarily related to neuroticism, and lower positive emotions, trust and competence. EC perfectionism accounted for unique variance in current depressive and anxious symptoms over and above the five‐factor domain scores. Copyright © 2011 John Wiley & Sons, Ltd.     

Characteristics of muscle dysmorphia in male football, weight training, and competitive natural and non-natural bodybuilding samples

The purpose of this study was to identify differences in traits associated with muscle dysmorphia between collegiate football players (n = 66), weight trainers for physique (n = 115), competitive non-natural bodybuilders (n = 47), and competitive natural bodybuilders (n = 65). All participants completed demographic questionnaires in addition to the Muscle Dysmorphia Inventory (Rhea, Lantz, & Cornelius, 2004). Results revealed a significant main effect for group, and post hoc tests found that the non-natural bodybuilding group did not score significantly higher than the natural bodybuilding group on any subscale except for Pharmacological Use. Both the non-natural and natural bodybuilding groups scored significantly higher than those that weight trained for physique on the Dietary Behavior and Supplement Use subscales. The collegiate football players scored lowest on all subscales of the Muscle Dysmorphia Inventory except for Physique Protection where they scored highest. Findings are discussed with future research expounded.     

Gender, neuroticism and speed-accuracy tradeoffs on a choice reaction-time task

The Eysenck Personality Questionnaire and Personality Inventory were administered to 96 college students, along with a choice reaction-time (RT)/movement-time task. The results show that females and Ss high on neuroticism made significantly fewer ballistic errors on the RT. The implications for RT research are discussed.     

Dichotomous Thinking and Personality Traits: From the Viewpoints of the Big Five and HEXACO1,2

Dichotomous thinking is a feature of certain personality traits, such as the Dark Triad and Cluster B personality disorders, which commonly reflect a fast life history strategy. The Big Five and HEXACO personality models are useful for understanding the personality structure and individual differences in life history strategy. Our study aimed to shed light on the propensity for dichotomous thinking using the framework of the Big Five and HEXACO personality models. Participants (n = 229) completed the Dichotomous Thinking Inventory, the 60-item HEXACO Personality Inventory – Revised, and the Ten-Item Personality Inventory. We examined correlations between dichotomous thinking and each domain of the Big Five and HEXACO personality models, and then computed multiple correlations predicting total and dimensional scores on the propensity for dichotomous thinking with scores on the Big Five and HEXACO personality traits. Results indicated that dichotomous thinking tendency is characterized by the set of low Agreeableness and Honesty–Humility. This study suggests that dichotomous thinking has antagonistic characteristics and a linkage to the fast life history strategy.     

Friendships of Indonesian,South Korean,and U.S. college students

The friendships of college students in the United States (n= 61), Indonesia (n= 56), and South Korea (n= 35) were assessed to evaluate the H. C. Triandis, R. Bontempo, M. J. Villareal, M. Asai, and N. Lucca (1988) hypothesis that the friendships of individuals in collectivist cultures are more intimate and less extensive than those in individualistic cultures. Students rated the qualities of their friendships, reported the identity and characteristics of friends, and recorded details of their social interactions using the Rochester Interaction Inventory. The friendship characteristics of South Korean students were generally consistent with the H. C. Triandis et al. (1988) hypotheses, whereas those of the Indonesian students were not. It appears that friendships in some collectivist cultures, including Indonesia, display characteristics of extensive social contacts with others in conjunction with limited intimacy with specific individuals.     

The curiosity and exploration inventory-II: Development, factor structure, and psychometrics

Given curiosity’s fundamental role in motivation, learning, and well-being, we sought to refine the measurement of trait curiosity with an improved version of the Curiosity and Exploration Inventory (CEI; [Kashdan, T. B., Rose, P., & Fincham, F. D. (2004). Curiosity and exploration: Facilitating positive subjective experiences and personal growth opportunities. Journal of Personality Assessment, 82, 291–305]). A preliminary pool of 36 items was administered to 311 undergraduate students, who also completed measures of emotion, emotion regulation, personality, and well-being. Factor analyses indicated a two-factor model—motivation to seek out knowledge and new experiences (Stretching; five items) and a willingness to embrace the novel, uncertain, and unpredictable nature of everyday life (Embracing; five items). In two additional samples (ns = 150 and 119), we cross-validated this factor structure and provided initial evidence for construct validity. This includes positive correlations with personal growth, openness to experience, autonomy, purpose in life, self-acceptance, psychological flexibility, positive affect, and positive social relations, among others. Applying item response theory (IRT) to these samples (n = 578), we showed that the items have good discrimination and a desirable breadth of difficulty. The item information functions and test information function were centered near zero, indicating that the scale assesses the mid-range of the latent curiosity trait most reliably. The findings thus far provide good evidence for the psychometric properties of the 10-item CEI-II.     

Comparing Job Applicants to Non‐applicants Using an Item‐level Bifactor Model on the HEXACO Personality Inventory

The present study evaluated the ability of item‐level bifactor models (a) to provide an alternative explanation to current theories of higher order factors of personality and (b) to explain socially desirable responding in both job applicant and non‐applicant contexts. Participants (46% male; mean age = 42 years, SD = 11) completed the 200‐item HEXACO Personality Inventory‐Revised either as part of a job application (n = 1613) or as part of low‐stakes research (n = 1613). A comprehensive set of invariance tests were performed. Applicants scored higher than non‐applicants on honesty‐humility (d = 0.86), extraversion (d = 0.73), agreeableness (d = 1.06), and conscientiousness (d = 0.77). The bifactor model provided improved model fit relative to a standard correlated factor model, and loadings on the evaluative factor of the bifactor model were highly correlated with other indicators of item social desirability. The bifactor model explained approximately two‐thirds of the differences between applicants and non‐applicants. Results suggest that rather than being a higher order construct, the general factor of personality may be caused by an item‐level evaluative process. Results highlight the importance of modelling data at the item‐level. Implications for conceptualizing social desirability, higher order structures in personality, test development, and job applicant faking are discussed.

Parental Attitudes of Farm,Town, and City Parents in Relation to Certain Personality Adjustments in their Children

Summary

Perceptual differences were investigated between 50 college students who were non-drug users and 50 hippies who used LSD. The groups were matched for race, sex, and age. No significant differences were found between intelligence and social class. The seven perceptual tests used were Color-Form Attention Test, Judgment of Sounds, Autokinetic Effect, Six-Inch Estimation, Rod and Frame Test, Estimation of Head Width, and Perceptual Acuity Test. The first hypothesis was that hippies would respond to the perceptual measures in a developmentally more primitive or childlike fashion than the college students. The second hypothesis was that hippies who reported mostly bad drug trips would be more like college students than the hippies who reported good drug trips.

The results support part of the first hypothesis in that hippies performed significantly differently from college students in the predicted direction on the Color-Form Attention, Judgment of Sounds, and Autokinetic Effect Tests only. No significant differences were found between hippies reporting good vs. bad drug trips. These findings are discussed in relation to perceptual style and theory.     

Adjective Checklist to Assess the Big Five Personality Factors in the Argentine Population

The aim of this work was to develop an adjective checklist to assess the Big Five personality factors in the Argentine population. The new instrument was administered to pilot (n= 112), validation (n= 372), and replication (n= 309) samples. The final version of the checklist included 67 adjectives encompassing its 5 dimensions. Factor analysis results were consistent with the Five-factor model. Internal consistency of scales was very good and convergent correlations with the Big Five Inventory (BFI; John, Donahue, & Kentle, 1991) were substantial. Face validity, as evaluated by 2 independent raters, was good. Preliminary evidence of validity for the checklist is presented. Finally, the Adjective Checklist for Personality Assessment and BFI are compared, taking into consideration their psychometric properties in our cultural context. Study limitations and future research are discussed.     

Prevalence of personality disorders among bulimics,nonbulimic binge eaters,and normal controls

We examined the comorbidity of bulimia and personality pathology among college women. Subjects included women (n=23) meeting DSM-III-R criteria for bulimia nervosa (bulimics), women (n=23) who reported binge eating but did not fulfill the criteria for bulimia nervosa (binge eaters), and women (n=23) who did not binge eat (normals). The subjects completed an assessment battery consisting of the Personality Disorders Examination and the SCID as well as the Beck Depression Inventory, the Rosenberg Self-Esteem Index, and measures of impulsivity and self-defeating tendencies. Fourteen of 23 bulimics (61%) met criterion for a personality disorder using DSM-III-R Axis II criteria. In comparison, 3 of 23 (13%) binge eaters and 1 of 23 (4%) normal subjects received an Axis II diagnosis. Borderline and self-defeating diagnoses were the predominant personality disorders in 96% of the bulimics exhibiting clinically significant personality pathology. Bulimics also exhibited significantly more depression, impulsivity, and self-defeating behavior and lower self-esteem than binge eaters and normals. The findings are discussed within a conceptual framework that posits an interaction between personality pathology and restrained eating.     

Behavioral,psychological, and historical correlates of MacAndrew scale scores among male alcoholics

Male alcoholic veterans (N=194) were divided into four groups on the basis of their scores on the MacAndrew scale (MAC) of the Minnesota Multiphasic Personality Inventory (MMPI) and compared on psychological and sociodemographic measures and self-reported alcohol, drug, and legal histories. Nineteen subjects scored in the nonalcoholic (NA) range of the MAC (i.e., false negatives, MAC23). Remaining subjects, scoring in the alcoholic range of the MAC, were divided into thirds by MAC scores (lowest third, L-MAC=24–28,n=53; middle third, M-MAC=29–31,n=63; highest third, H-MAC>31,n=59). Groups did not differ on age, any important sociodemographic variables, or scores on the Profile of Mood States, State-Trait Anxiety Inventory, Symptom Checklist-90, or Rod and Frame Test. Significant group differences were obtained on several MMPI scales. Lower MAC scores were associated with higher scores onL, K, D, andR, and lower scores onMa. There was also a tendency for subjects with lower MAC scores to score higher onSi. NA subjects began drinking and heavy drinking later than other subjects, although groups did not differ on duration, quantity, or frequency of drinking. Subjects with higher MAC scores more often reported drinking in bars, drinking liquor straight, alcohol-related job disruptions, and previous use of marijuana, hallucinogens, and barbiturates. Subjects with higher MAC scores had more often been arrested, convicted, fined, and jailed for alcohol-related offenses but not for other offenses. Results are examined with respect to MacAndrew's distinction between primary and secondary alcoholics and with respect to the possible relations of MAC to important person variables such as sensation seeking.The authors wish to thank Craig MacAndrew for his helpful critical reading of an early draft of this paper.

Symptoms,blood-pressure information and mood effects on symptom recall

Abstract

After completion of an illness symptom checklist (PILL) covering the previous three months, 97 nor-motensives were allocated to either experimental (false pressor feedback, n=42), or information control (accurate pressor feedback, n = 55), groups. The median reported symptom score divided high from low symptom subjects. All were given standard cuff blood pressure (BP) assessment and were normotensive. However, experimental subjects were misinformed that their BP was raised while information control subjects were told their BP was normal. Subsequently, subjects completed the state anxiety form of the State-Trait Personality Inventory, the PILL, and were asked about their belief of the ascribed BP label (normo/hypertensive) and then any perceived causal relationship between their BP and symptoms. Experimental subjects had significantly higher anxiety scores but no change in symptom recall after pressor feedback, whereas control subjects showed lower anxiety scores and decreases in symptom recall.

A post hoc treatment control (no pressor information) group (n = 20) excluded effects of BP labeling on post-BP scores, and a post hoc symptom control group (n = 55) ensured that symptom levels were representative of the normal population. The majority of subjects in both groups rejected any association between BP labels and symptoms. Data are discussed in the light of Leventhal's models of illness representation.     

Basic visual perceptual processes in children with typical development and cerebral palsy: The processing of surface,length, orientation,and position

The present study aims to assess how the processing of basic visual perceptual (VP) components (length, surface, orientation, and position) develops in typically developing (TD) children (n = 215, 4–14 years old) and adults (n = 20, 20–25 years old), and in children with cerebral palsy (CP) (n = 86, 5–14 years old) using the first four subtests of the Battery for the Evaluation of Visual Perceptual and Spatial processing in children. Experiment 1 showed that these four basic VP processes follow distinct developmental trajectories in typical development. Experiment 2 revealed that children with CP present global and persistent deficits for the processing of basic VP components when compared with TD children matched on chronological age and nonverbal reasoning abilities.     

Eysenck Personality Questionnaire scales and paper-and-pencil tests related to creativity

Pearson correlations for scores on scales of the 1975 version of the Eysenck Personality Questionnaire with measures of schizotypy, hypomania, and creative traits are reported for 625 undergraduates. The Psychoticism scores are correlated .30 with Hypomanic traits, .25 with Perceptual Aberration, and .20 with the How Do You Think, a test of attitudes and activities related to creativity. Extraversion is also related to creativity-relevant scores. Results support a broad and nonspecific role for the Psychoticism scale in relation to both creativity and subclinical symptomatology.     

Race,Exclusionary Discipline,and Connectedness to Adults in Secondary Schools

This study examines racial differences in students' connectedness to school adults and considers the possibility that disparities in exclusionary discipline practices may reduce all students' sense of connection to educators, not just those who have been disciplined or are from racial groups overrepresented in out‐of‐school suspensions. Data sources include a self‐report survey of secondary school students (n = 29,148) linked to administrative data (n = 107 schools) from a large urban district. Multilevel modeling techniques were used to estimate the relationships between students' racial background, youths' connection to school adults, and school‐level racial discipline gaps. Controlling for school racial composition, gender, grade level and other covariates, students of color were significantly less likely to feel connected to school adults than their White peers. Additionally, the racial discipline gap was significantly and negatively associated with connectedness for all students. Results indicate that strategies to improve educational outcomes for youth of color need to attend to relational dynamics between students and school adults. Research findings also suggest that efforts to reduce discipline disparities may improve all students' connectedness.
