EMG Activity as a Function of the Performer's Focus of Attention

In previous studies of attentional focus effects, investigators have measured performance outcome. Here, however, the authors used electromyography (EMG) to determine whether differences between external and internal foci would also be manifested at the neuromuscular level. In 2 experiments, participants (N = 11, Experiment 1; N = 12, Experiment 2) performed biceps curls while focusing on the movements of the curl bar (external focus) or on their arms (internal focus). In Experiment 1, movements were performed faster under external than under internal focus conditions. Also, integrated EMG (iEMG) activity was reduced when performers adopted an external focus. In Experiment 2, movement time was controlled through the use of a metronome, and iEMG activity was again reduced under external focus conditions. Those findings are in line with the constrained action hypothesis (G. Wulf, N. McNevin, & C. H. Shea, 2001), according to which an external focus promotes the use of more automatic control processes.     

Gender Roles,Suicide Attempts,and Substance Abuse

In this article, the focus is on a comparison of suicide attempts and substance abuse in the United States. It is argued that suicide attempts and substance abuse may function as psychologically equivalent but gender-specialized forms of self-injurious behaviors. Possible explanations for the gender segregation of suicide attempts and substance abuse are reviewed, and the benefits of crossover theories and treatments are presented.     

Effects of Aggressive and Nonaggressive Rock Songs on Projective and Structured Tests

The differences between hostility scores on projective and objective tests as a function of listening to aggressive or nonaggressive rock music were studied. While taking the Thematic Apperception Test (Cards 1, 3BM, 4, 9BM, and 10) and the Buss-Durkee (1957) Hostility Scale, subjects (N = 90) randomly assigned to one of three groups listened to a rock song with (a) nonaggressive music and non-aggressive lyrics, (b) aggressive music and nonaggressive lyrics, or (c) aggressive music and aggressive lyrics. TAT stories were scored for aggressive content according to Hafner and Kaplan's (1960) hostility rating scale. Hostility scores did not differ between groups. The findings are congruent with other investigators' reports that subjects do not pay attention to rock lyrics. Previous findings that music affects the emotional quality of TAT stories and hostility scores on the Buss-Durkee scale were not supported.     

Relationships Between Need for Cognition,Knowledge, and Verbal Ability

The authors investigated the relationships between need for cognition. knowledge, and verbal ability. Participants completed scales that measured their need for cognition, verbal ability, and knowledge about people and events that occurred during the Vietnam War era. Correlational analyses showed that the participants' need for cognition scores were modestly but positively correlated with verbal ability and knowledge and that verbal ability and knowledge were also positively correlated. The correlation between need for cognition and knowledge was small but significant when verbal ability was controlled. The conclusion drawn from these results is that need for cognition contributes to the acquisition of knowledge beyond the contribution of verbal ability.     

Need for Cognition and Cognitive Performance From a Cross-Cultural Perspective: Examples of Academic Success and Solving Anagrams

The cross-cultural validity of the Need for Cognition Scale and its relationship with cognitive performance were investigated in two studies. In the first study, the relationships between the scale and university entrance scores, course grades, study skills, and social desirability were examined. Using the short form of the Turkish version of the Need for Cognition Scale (S. Gülgöz & C. J. Sadowski, 1995) no correlation with academic performance was found but there was significant correlation with a study skills scale and a social desirability scale created for this study. When regression analysis was used to predict grade point average, the Need for Cognition Scale was a significant predictor. In the second study, participants low or high in need for cognition solved multiple-solution anagrams. The instructions preceding the task set the participants' expectations regarding task difficulty. An interaction between expectation and need for cognition indicated that participants with low need for cognition performed worse when they expected difficult problems. Results of the two studies showed that need for cognition has cross-cultural validity and that its effect on cognitive performance was mediated by other variables.     

The Prediction of Students' Satisfaction with Community College Vocational Training

The present study was conducted with 1,632 college vocational students in North Carolina to test the job satisfaction postulate of Rusbult's (1980a) investment model. The model postulate, that satisfaction is a function of perceived positive and negative outcomes, received support and proved to be defensible even after controlling for a broad array of situational variables. This postulate has also received empirical support from studies of satisfaction with business relationships, friendships, and romantic associations. The present study also introduced a new measure of outcomes: the Perceived Outcomes of College Life measure.     

Aurelius Augustine on Imagination

The evaluation of a person seeking or volunteering information in cooperatively or competitively oriented problem solving groups was investigated in 63 white and black, male and female, high school and college students. It was hypothesized that under cooperative conditions the seeking of information would be evaluated more positively than would the volunteering of information, while under competitive conditions the volunteering of information would be evaluated more positively than would the seeking of information. A highly trained confederate (C) engaged in either the seeking of information or the volunteering of information in four-person problem solving groups in which Ss were either cooperatively or competitively oriented. Ss rated Cs on eight bipolar scales. The results confirmed the hypothesis.     

False Memories in Individuals at Risk for Developing an Eating Disorder

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.     

A Multiphasic Personality Schedule (Minnesota): III. the Measurement of Symptomatic Depression

La Fave's habit lag construct, which specifies conditions under which previously automatized motor responses become disruptive of subsequent performance, was tested. Performance under stress was also examined as a possible factor in the occurrence of habit lag. Following a visual discrimination task, 48 women performed motor responses simultaneously: (a) repeating an invariant lever movement and (b) pushing one of two keys. The habit lag construct was supported, as Ss who had automatized responses produced more errors than nonautomatized Ss. Performance under stress, by calling attention to the risk of habit lag, reduced errors. Habit lag accounts for an intrusive type of error often found in motor performance where negative transfer fails to do so.     

Advancing the trait EI content domain: Further evidence for the distinctiveness of interpersonal facets

This investigation sought to assess the congruence of the trait emotional intelligence (EI) sampling domain, reflected in the short form of the Trait Emotional Intelligence Questionnaire (TEIQue; Petrides & Furnham, 2006), with the theoretical content of trait EI—namely, the range of personality traits implicated in emotions. First, associations of the TEIQue factors with Emotion-Oriented Coping (EOC) and Social Coping (SC) were compared. Three of the four TEIQue factors were stronger predictors of EOC than SC; only the Emotionality factor was a stronger predictor of SC. Also, Emotionality did not add to the prediction of EOC in a simultaneous regression with the other factors. Secondly, by means of Structural Equation Modelling, the 30-item composite and a theoretically altered 16-item composite were compared as mediators between the Big Five and the emotion-laden dimension of mental health. Even though all interpersonal items (i.e., those pertaining to Sociability and Emotionality) were omitted for the altered composite, it outperformed the original composite in predicting a latent mental health composite of Stress, Anxiety, and EOC. The results highlight the distinct nature of Emotionality and Sociability facets and have implications for the refinement of the trait EI content domain.
