Neurobehavioral evidence for the "Near-Miss" effect in pathological gamblers

The purpose of this translational study was twofold: (1) to contrast behavioral and brain activity between pathological and nonpathological gamblers, and (2) to examine differences as a function of the outcome of the spin of a slot machine, focusing predominately on the "Near-Miss"--when two reels stop on the same symbol, and that symbol is just above or below the payoff line on the third reel. Twenty-two participants (11 nonpathological; 11 pathological) completed the study by rating the closeness of various outcomes of slot machine displays (wins, losses, and near-misses) to a win. No behavioral differences were observed between groups of participants, however, differences in brain activity were found in the left midbrain, near the substantia nigra and ventral tegmental area (SN / VTA). Near-miss outcomes uniquely activated brain regions associated with wins for the pathological gamblers and regions associated with losses for the nonpathological gamblers. Thus, near-miss outcomes on slot machines may contain both functional and neurological properties of wins for pathological gamblers. Such a translational approach to the study of gambling behavior may be considered an example that gives life to B. F. Skinner's conceptualization of the physiologist of the future.     

Musical preference, deviance, and attitudes towards music celebrities

Two studies investigated the relationship among British students between liking for ‘problem’ music, indices of deviance, and scores on a slightly modified version of the Celebrity Attitude Scale (CAS). Study 1 indicated a positive relationship between liking for ‘problem’ music styles and psychoticism scores. Study 2 indicated that fans of ‘problem’ music scored higher than non-fans on measures of psychoticism, reactive rebelliousness, and two specific problem behaviours; that liking for ‘problem’ music was related only to psychoticism when all the indices of deviance were considered together in a multiple regression; and that fans of ‘problem’ music did not score higher on CAS measures of identification with the participants’ favourite musicians. The present data indicate a relationship outside North America between ‘problem’ music and deviance, that this might be attributable primarily to elevated psychoticism scores among listeners to this music, but that liking for ‘problem’ music was not associated with a greater tendency for participants to identify closely with licentious behaviours carried out by pop musicians.     

Personality characteristics of opiate addicts

18 Ss dependent on opiate drugs completed three personality trait questionnaires, and were compared with 18 controls matched for demographic variables. The drug dependent sample were significantly higher than controls in psychoticism, but lower in extraversion and telic dominance. No difference between the groups was found in locus of control. These data are compared with existing research.     

The Relation of Candidate Personality With Selection-Interview Outcomes

Two studies examined the relation of personality on the interview process. Study 1 was designed to examine these behaviors and characteristics in a lab sctting. while Study 2 examined similar variables in a field setting. Study 1 demonstrated that Type A achievemetit strivings, extraversion, work locus of control. neuroticism. and trait anxiety were related to interview outcomes in simulated employment interviews. Study 2 examined the relation of personality characteristics to outcomes of actual interviews conducted by college recruiters. Type A achievement striving, work locus of control. and trait anxiety were found to be related to interviewer decision outcomes.     

An evaluation of response allocations to concurrently available slot machine simulations

Gambling behavior often involves making choices between concurrently available game options. With regard to slot machine gambling, multiple games allow for choices to be made with respect to which game to play. The authors of the present study used a slot machine simulation created in Visual Basic. NET to examine gambling preference. The specific question addressed was whether gamblers prefer a smaller payout more often (averaging around every 10 spins) over a larger payout less often (averaging around every 50 spins). Two types of reinforcement were examined during the study: frequency of payouts and the amount of credits won. The results indicate that participants had a preference for a slot machine with the more frequent payout as opposed to one with more intermittent payout. These results support existing literature on theories of choice and provide a step toward understanding human gambling behavior.     

Perception of childhood dissatisfaction with parents and selected personality traits in adulthood

This study tested the hypotheses that perceptions of childhood dissatisfaction with parents are associated with higher scores on measures of intensity and chronicity of loneliness, anxiety, neuroticism, psychoticism, misanthropy, and external locus of control and lower scores on measures of self-esteem and sociability. The subjects were 537 Iranian students studying in American and Iranian universities. Both hypotheses were confirmed in a multivariate statistical model. We also found that dissatisfaction with parents was related to a lack of satisfactory relationships with peers.     

Locus of control, self-control, and family income as predictors of young children's mathematics and science scores

Locus of control, self-control, and family income were investigated as possible predictors of 138 young children's mathematics and science scores. The children, 60 boys and 78 girls, ranging from 4 to 8 years of age (M = 5.4, SD = 1.3) were administered the Stephens-Delys Reinforcement Contingency Interview Scale, the Self-control Rating Scale, the Comprehensive Mathematics Inventory, and a science test based on the work of D. K. Dickinson. Analysis showed mathematics scores were positively related to income, locus of control, and science scores. Mathematics and science scores were negatively related to lack of self-control. Also, science scores were positively related to locus of control. Multiple regression analysis with mathematics as the dependent variable indicated income had the greatest predictive value followed by self-control and locus of control. The multiple regression model of science was also significant, with locus of control having the greatest influence followed by self-control.     

Gambling behavior and gambling problems in Norway 2007

In Norway, legalized gambling is pervasive, easily accessible and socially accepted, particularly the participation in national lotteries. We conducted a stratified probability sample study during January–March 2007 (age group 16–74 years, N  = 3,482, response rate 36.1%) to assess gambling behavior and prevalence of problematic gambling by the NORC Diagnostic Screen (NODS). Overall, 67.9% of the study population had been engaged in past-year gambling and 0.7% were past-year problematic gamblers (NODS score 3+). Male gender, low educational level, single marital status, and being born in a non-Western country were variables positively associated with problematic gambling. Past-year problematic gamblers indicated the slot machine (34.6%) and Internet gambling (26.9%) as the most important games, while most non-problematic gamblers pointed out the lotteries (62.3%) as the most important game. The prevalence of self-reported sleeping disorders, depression and other psychological impairments was significantly higher among problematic gamblers. Gambling problems affect people's lives in multiple ways.     

Social Deviancy and Suicidal Behavior

Abstract

In this study lottery gambling behavior of 288 American college students was examined. Although most students were infrequent gamblers, we found that student lottery gambling was related to having parents and friends who were lottery gamblers. Students who were frequent lottery gamblers were more likely to participate in other forms of gambling and to have begun gambling at younger ages than less frequent gamblers. Locus of control was related to more frequent gambling among parents and only marginally related to more frequent lottery play among students. Discriminant analysis using parental gambling, peer gambling, games played, sex, and locus of control could predict frequency of lottery playing for 72% of gamblers and nongamblers.     

Characterization of controlled gamblers and pathological gamblers using the social representation theory

Introduction

In industrialized countries, gambling disorder tends to become a major issue. The use of the social representation theory provides clues for a better understanding of pathological gamblers.

The Theory of Male Reference Group Identity Dependence: Roles of Social Desirability, Masculinity Ideology, and Collective Identity

Data from 118 college men from the southeastern United States (U.S.) were analyzed using zero-order and partial correlations to test male reference group identity dependence theory’s propositions regarding the relations of male reference group identity attitudes (i.e., no reference group, reference group dependent, reference group nondependent similarity, and reference group nondependent diversity) with traditional masculinity ideology and dimensions of men’s gender-based collective identity (i.e., affirmative evaluation of collective identity, importance of collective identity). Male reference group identity attitudes yielded theoretically-consistent relations with the affirmative evaluation and importance of collective identity. Specifically, the no reference group attitudes were correlated negatively whereas nondependent diversity attitudes were correlated positively with affirmative evaluation; the group dependent attitudes were correlated positively with importance of collective identity; and the nondependent similarity attitudes were correlated positively with both affirmative evaluation of collective identity and the importance of collective identity. This pattern reveals the differential salience of collective identity dimensions in male reference group identity attitudes, suggesting that group dependent attitudes reflect importance of collective identity without an evaluation valence, nondependent diversity attitudes reflect affirmative evaluation whereas the no reference group attitudes reflect nonaffirmative evaluation of collective identity, and nondependent similarity attitudes involve both affirmative evaluation and importance of collective identity. Additional findings added to prior data suggesting reevaluation of the posited role of traditional masculinity ideology in male reference group identity theory. The pattern of findings was not changed by controlling for self-deceptive enhancement and impression management dimensions of social desirability.     

Effects of test-wiseness training on test anxiety,locus of control and reading achievement in elementary school children

Abstract

Fifth and sixth grade children were randomly assigned to either a control or an experimental condition in a pretest, posttest, delayed posttest design. The experimental group received instruction and practice in test-taking, and the control group received a placebo treatment. Dependent variables were four components of test anxiety, locus of control and achievement. Factor analysis of pretest data supported I. Sarason's four-factor conceptualization of test anxiety (worry, test-irrelevant thinking, tension, and bodily reactions to test taking). Posttest data generally supported the hypothesized treatment effects. As predicted, children in the experimental condition had higher reading scores, greater internality, and less test-irrelevant thinking. The delayed posttest scores indicated a diminished effect on the achievement and internality measures; however, the amount of test-irrelevant thinking remained lower in the experimental condition.     

Preference for situations involving effort, time pressure, and feedback in relation to type A behavior, locus of control, and test anxiety

Eighty subjects from an introductory psychology course rated the desirability of eight course structures that differed according to all combinations of the presence or absence of effort required for success, time pressure, and the provision of feedback. Subjects also completed questionnaire measures of the Type A behavior pattern, test anxiety, and external locus of control. Results showed that the Type A behavior pattern was negatively related to external locus of control and that externals tended to have higher test anxiety scores than internals. Multiple regression analyses that involved the personality variables and age and gender showed that the Type A variable predicted preference for course structures that involved effort and feedback and that external control predicted preference for course structures that were independent of effort and provided little feedback. Test anxiety and desirability ratings were positively correlated for the course structure that was not dependent on effort, had little time pressure, and had little feedback. The results were consistent with the view that individuals seek out and prefer situations that are consistent with their personality characteristics.     

Decreasing influence of arbitrarily applicable verbal relations of recreational gamblers: A randomized controlled trial

Twenty‐one recreational gamblers were randomly assigned to two groups; one group was exposed to a conditional discrimination relational training task to bias choice allocation to a black machine presented concurrently with a red machine, and the other group underwent the same relational training task immediately followed by a defusion procedure, designed to expand upon the relations developed in the initial relational task. Both groups completed a simulated slot‐machine task before and after the relational training task, with or without the defusion procedure. Results showed that 9 of 11 participants in the relational training only group showed an increased bias toward the black machine, compared to only 4 of 10 in the relational training plus defusion group; this latter group also showed greater matched responding. Results suggest that expanding verbal–relational networks may reduce the influence of any single verbal relation on gambling choice behavior.     

ALTERING THE NEAR‐MISS EFFECT IN SLOT MACHINE GAMBLERS

This study investigated the potential for recreational gamblers to respond as if certain types of losing slot machine outcomes were actually closer to a win than others (termed the near‐miss effect). Exposure to conditional discrimination training and testing disrupted this effect for 10 of the 16 participants. These 10 participants demonstrated high percentages of conditional discrimination testing performance, and the remaining 6 participants failed the discrimination tests. The implications for a verbally based behavioral explanation of gambling are presented.     

Pathological gambling and obsessive-compulsive spectrum disorders

To test the hypothesis that pathological gambling can be classified as an Obsessive-Compulsive Spectrum Disorder, the Padua Inventory was administered to 40 diagnosed pathological gamblers and a control group of 40 normal subjects. Analysis showed that the pathological gamblers obtained a significantly higher mean total score on obsessionality than controls. Elevated scores on two factors reflecting impaired control of mental activities and loss of motor control contributed to the over-all difference. In the context of other research suggesting pathological gamblers would score high on psychometric measures of impulsivity, this study provides preliminary support for a Spectrum Disorder Model, suggesting that pathological gamblers are characterised by elevated scores on traits of 'impulsivity' and 'obsessionality.'     

Psychometric characteristics and dimensionality of a Persian version of Rosenberg Self-esteem Scale

The Rosenberg Self-esteem scale was translated into Persian and 12 Iranian bilingual judges confirmed the soundness of translation. The psychometric properties of the Persian version of Rosenberg Self-esteem Scale were studied in two samples of Iranian college students separately. Sample I consisted of 232 Iranian students in American universities, and Sample II comprised 305 Iranian students in Iranian universities. Criterion measures of loneliness, depression, anxiety, neuroticism, psychoticism, misanthropy, locus of control, tendency to dissimulate, and measures of relationship with parents, peers, and academic achievement were obtained. Item-total score correlations and alpha reliabilities supported the internal consistency of the scale. Test-retest reliabilities indicated the stability of the scores, and correlations between scores of the scale, and criterion measures supported the concurrent validity of the Rosenberg scale. Factor analysis of the Rosenberg scores confirmed the unidimensionality of the scale.     

The Animal = Male Hypothesis: Children's and Adults' Beliefs About the Sex of Non–Sex-Specific Stuffed Animals

The Animal = Male Hypothesis, a variation of Silveira's People = Male Hypothesis (Silveira, 1980), was examined. In Study 1, children ages 3–10 years and adults told stories about a gender-neutral stuffed animal, in Study 2 children ages 5–6 years told stories about 3 neutral and 3 feminine animals, and in Study 3 children ages 5–7 years told stories about 2 neutral animals, observed an adult model use feminine pronouns to refer to an animal, then told stories about 2 more animals. Dependent variables were the pronouns participants used to refer to the animals and what sex they believed the animals were. Results showed strong evidence for an animal = male bias in all 3 studies among children and adults of both sexes on both dependent measures. There were few sex-related differences. The modeling intervention was not successful in reducing the bias.     

Assessment of irrational health beliefs: relation to health practices and medical regimen adherence.

The purpose of the present research was to provide initial validation of the 20-item Irrational Health Belief Scale (IHBS). Study 1 included 392 undergraduate psychology students. Results from Study 1 suggested that the IHBS total score is internally consistent and stable over an 18-month time period. Greater health-related cognitive distortion (higher IHBS scores) was associated with weaker internal health locus of control beliefs, lower positive affectivity, stronger chance health locus of control beliefs, and greater negative affectivity. Most important, greater cognitive distortion was uniquely and significantly associated with a less positive pattern of health practices. Study 2 involved 107 individuals with Type I diabetes mellitus. Results indicated that higher IHBS scores were significantly associated with both objective (hemoglobin HbA1) and self-reported diabetic regimen adherence independent of trait neuroticism and conscientiousness.     

Transportation,Stress, and Community Psychology

Conditions of transportation were investigated as sources of psychological stress as they affect the physiology, task performance, and mood of commuters. Participants in the study were 100 employees of industrial firms. Traffic congestion was construed as a behavioral constraint in terms of the concept of impedance which is defined by the parameters of distance and time. It was expected that the effects of impedance would be mediated by personality factors, such as locus of control. Multivariate tests of the internal validity of the impedance factor were significant. However, significant main effects for impedance were obtained only for mood and residential adaptation. The predicted interactions of impedance with locus of control were obtained across task performance indices. In multiple regression analyses, the distance and speed of the commute to work were found to account for significant proportions of variation in blood pressure, while several indices of personal control had significant regression effects on the task measures. The implications of the results for research in community psychology are discussed.
