The effects of simulated stuttering and prolonged speech on the neural activation patterns of stuttering and nonstuttering adults

Functional magnetic resonance imaging was used to investigate the neural correlates of passive listening, habitual speech and two modified speech patterns (simulated stuttering and prolonged speech) in stuttering and nonstuttering adults. Within-group comparisons revealed increased right hemisphere biased activation of speech-related regions during the simulated stuttered and prolonged speech tasks, relative to the habitual speech task, in the stuttering group. No significant activation differences were observed within the nonstuttering participants during these speech conditions. Between-group comparisons revealed less left superior temporal gyrus activation in stutterers during habitual speech and increased right inferior frontal gyrus activation during simulated stuttering relative to nonstutterers. Stutterers were also found to have increased activation in the left middle and superior temporal gyri and right insula, primary motor cortex and supplementary motor cortex during the passive listening condition relative to nonstutterers. The results provide further evidence for the presence of functional deficiencies underlying auditory processing, motor planning and execution in people who stutter, with these differences being affected by speech manner.     

Psychological factors predicting stress symptoms: metacognition, thought control, and varieties of worry

This study tested predictions of the metacognitive model of post-traumatic stress disorder (Wells, 2000) concerning relationships between stress symptoms and maladaptive control of thoughts. We tested the hypothesis that the tendency to use worry as a means of controlling thoughts will be positively predictive of stress symptoms. In doing so, overlaps with symptomatic worry, stress symptoms, and stress exposure at time 1 was controlled. One hundred and ten (110) college students were assessed twice, over a three-month period. Consistent with predictions, use of worry as a thought control strategy made a significant and independent contribution to the prediction of stress symptoms. The findings provide further support for Wells' metacognitive model of stress reactions.     

Personality,age, and fluid intelligence

A total of 383 participants (aged 19 to 66 years) completed the Raven's Progressive Matrices, the Myers‐Briggs Type Indicator (MBTI), the Fundamental Interpersonal Relations Orientation‐Behavior (FIRO‐B), and the California Psychological Inventory‐434 (CPI‐434). Results showed that IQ was positively correlated with perceiving (MBTI), control (FIRO‐B), intellectual efficiency (CPI‐434), achievement via independence (CPI‐434), and negatively correlated with sensing (MBTI), internality (CPI‐434) and norm‐favouring (CPI‐434), supporting the majority of the hypotheses. Participants' age was correlated with many measures, particularly intelligence and accounted for a third of the variance in IQ scores. Limitations are considered.     

Attitudes,knowledge, and use of alcohol in university students

This paper investigated attitudes towards alcohol, knowledge of alcohol, parents drinking behaviour, reasons for drinking and television viewing habits varied in relation to actual drinking behaviour. A sample of 106 University students completed a questionnaire which enabled their classification as non, light, medium and heavy drinkers on the basis of their self-reported consumption levels. Results revealed 9% to be non-drinkers, 22% to be light, 38% to be moderate and 31% to be heavy. They also showed that alcohol drinking habits differed significantly with age, sex, smoking habits and in particular with parents drinking habits. Alcohol drinking habits also differed significantly with knowledge of alcohol, heavier drinkers being found to have a better overall knowledge, but reasons for drinking and attitudes towards drinking did not show any overall difference between the drinking habit categories. Finally, there was no indication that television viewing independently contributed to alcohol beliefs, knowledge, attitudes or habits. The results are discussed in terms of future research implications.     

The Effect of Music on Atmosphere and Purchase Intentions in a Cafeteria1

This exploratory study investigates the effect of music on the perceived characteristics of a commercial listening environment and on customers' purchase intentions therein. Three musical styles and also no music were played in a student cafeteria over the course of 4 days. Subjects' responses to a questionnaire indicated that different musical styles had different effects on the perceived characteristics of the cafeteria, and that classical music was associated with subjects being prepared to pay the most for food items on sale therein. There was also some indication that classical and pop music might have increased actual sales in the cafeteria, as compared with easy listening and silence. These results are discussed in terms of their implications for both commercial practice and our theoretical understanding of music and consumer behavior.     

Affective and evaluative responses to pop music

From reviews published in the “serious” pop music press, twenty recordings were selected which had received consistently favourable appraisals on affective and evaluative bases. A further twenty recordings were selected on the basis of high levels of chart performance but a lack of critical acclaim. Sixty-four subjects rated representative excerpts of these recordings on 11-point scales of either liking or artistic merit. The results indicated significantly lower liking and artistic merit ratings of critically praised excerpts; a positive liking-artistic merit correlation; and some “fragmentation” between affective and evaluative responses. The apparent discrepancy between the attitudes of the music press and subjects' ratings is discussed in terms of the availability and sophistication of evaluation cues.
