Picking up the pace: effects of global temporal context on sensitivity to the tempo of auditory sequences

This article continues a line of research examining factors affecting listeners' auditory tempo sensitivities. Of particular interest is the question of whether listeners are sensitive to the overall (global) pace of their auditory environment and how this sensitivity may affect their perceptions of sequence timing. To address this question, we manipulated the set of sequence tempi (between 300 and 700 msec) that listeners experienced over the course of a 1-h period (i.e., the global temporal context) while they performed a tempo-discrimination task involving standard-comparison pairs of isochronous tone sequences. Overall findings show systematic distortions in perceived tempo that are consistent with the view that listeners adapt to the global pace of their auditory environments. Moreover, general support was found for the hypothesis that increasing the number of equal intervals in a standard sequence produces greater improvements in tempo sensitivity when the standard sequence tempo is different from the global pace than when it is at the global pace. Implications of these findings for models of timing and temporal processing are discussed.     

Personality Predicts Obedience in a Milgram Paradigm

This study investigates how obedience in a Milgram‐like experiment is predicted by interindividual differences. Participants were 35 males and 31 females aged 26–54 from the general population who were contacted by phone 8 months after their participation in a study transposing Milgram's obedience paradigm to the context of a fake television game show. Interviews were presented as opinion polls with no stated ties to the earlier experiment. Personality was assessed by the Big Five Mini‐Markers questionnaire (Saucier, 1994). Political orientation and social activism were also measured. Results confirmed hypotheses that Conscientiousness and Agreeableness would be associated with willingness to administer higher‐intensity electric shocks to a victim. Political orientation and social activism were also related to obedience. Our results provide empirical evidence suggesting that individual differences in personality and political variables matter in the explanation of obedience to authority.     

Effect of a behavioral intervention on dimensions of self-regulation and physical activity among overweight and obese adults with type 2 diabetes: a pilot study

The purpose of this pilot study was to determine the preliminary effect of a behavioral intervention on the use of self-regulation strategies and moderate-to-vigorous physical activity (MVPA) in overweight and obese adults with type 2 diabetes. 23 individuals recruited from ResearchMatc.org and campus advertisements were randomized into an intervention (n = 12) and control (n = 11) group. The intervention group received a behavioral intervention that used goal setting, time management, and self-monitoring to target dimensions of self-regulation and MVPA. The control received information regarding their PA habits. MVPA was measured via BodyMedia Armbands at pre- and post-test. The use of self-regulatory strategies for MVPA was assessed at pretest and posttest using the Self-Regulation for Exercise Scale. Cohen’s d effect sizes were calculated to determine the practical impact of the intervention. The intervention had a large effect on all dimensions of self-regulation across time: including total self-regulation (3.15), self-monitoring (4.63), goal setting (3.17), social support (1.29), self-reward (1.98), time management (4.41), and overcoming barriers (2.25). The intervention had no impact on dimensions of MVPA across time. This pilot study demonstrated the ability of a behavioral intervention to improve the use of self-regulation strategies for MVPA in a sample of adults with type 2 diabetes. These findings can further inform the development of health promotion programs to promote self-regulation. Future research should focus on determining ability of improvements in self-regulation to stimulate behavior change.     

Relations among Social Anxiety,Eye Contact Avoidance,State Anxiety,and Perception of Interaction Performance during a Live Conversation

There is building evidence that highly socially anxious (HSA) individuals frequently avoid making eye contact, which may contribute to less meaningful social interactions and maintenance of social anxiety symptoms. However, research to date is lacking in ecological validity due to the usage of either static or pre-recorded facial stimuli or subjective coding of eye contact. The current study examined the relationships among trait social anxiety, eye contact avoidance, state anxiety, and participants’ self-perceptions of interaction performance during a live, four-minute conversation with a confederate via webcam, and while being covertly eye-tracked. Participants included undergraduate women who conversed with same-sex confederates. Results indicated that trait social anxiety was inversely related to eye contact duration and frequency averaged across the four minutes, and positively related to state social anxiety and negative self-ratings. In addition, greater anticipatory state anxiety was associated with reduced eye contact throughout the first minute of the conversation. Eye contact was not related to post-task state anxiety or self-perception of poor performance; although, trends emerged in which these relations may be positive for HSA individuals. The current findings provide enhanced support for the notion that eye contact avoidance is an important feature of social anxiety.     

The disguise of sobriety: unveiled by alcohol in persons with an aggressive personality

This investigation examined the factor structure of 8 well-validated self-report measures that assess traits that fall under the rubric of an "aggressive personality" and then determined how those factor(s) moderated the association between alcohol intoxication and aggression. Participants were 518 (252 men and 266 women) healthy social drinkers between 21 and 35 years of age. Following the consumption of an alcoholic or a placebo beverage, participants were tested on a laboratory aggression paradigm in which electric shocks were received from, and administered to, a fictitious opponent. Aggression was operationalized as the shock intensities and durations administered to the opponent. Results demonstrated a unidimensional factor structure for the aggressive personality traits, which were then combined into a latent variable. The aggressive personality variable moderated the alcohol-aggression relation. Specifically, alcohol was significantly more likely to increase aggression in persons with higher, compared with lower, aggressive personality scores.     

Effects of musicality and motivational orientation on auditory category learning: A test of a regulatory-fit hypothesis

Two experiments investigated the effects of musicality and motivational orientation on auditory category learning. In both experiments, participants learned to classify tone stimuli that varied in frequency and duration according to an initially unknown disjunctive rule; feedback involved gaining points for correct responses (a gains reward structure) or losing points for incorrect responses (a losses reward structure). For Experiment 1, participants were told at the start that musicians typically outperform nonmusicians on the task, and then they were asked to identify themselves as either a “musician” or a “nonmusician.” For Experiment 2, participants were given either a promotion focus prime (a performance-based opportunity to gain entry into a raffle) or a prevention focus prime (a performance-based criterion that needed to be maintained to avoid losing an entry into a raffle) at the start of the experiment. Consistent with a regulatory-fit hypothesis, self-identified musicians and promotion-primed participants given a gains reward structure made more correct tone classifications and were more likely to discover the optimal disjunctive rule than were musicians and promotion-primed participants experiencing losses. Reward structure (gains vs. losses) had inconsistent effects on the performance of nonmusicians, and a weaker regulatory-fit effect was found for the prevention focus prime. Overall, the findings from this study demonstrate a regulatory-fit effect in the domain of auditory category learning and show that motivational orientation may contribute to musician performance advantages in auditory perception.     

Individual differences and state effects on mind-wandering: Hypnotizability, dissociation, and sensory homogenization

Consciousness alterations can be experienced during unstructured, monotonous stimuli. These effects have not been linked to particular cognitive operations; individual differences in response to such stimulation remain poorly understood. We examined the role of hypnotizability and dissociative tendencies in mind-wandering (MW) during a sensory homogenization procedure (ganzfeld). We expected that the influence of ganzfeld on MW would be more pronounced among highly hypnotizable individuals (highs), particularly those high in dissociative tendencies. High and low hypnotizables, also stratified by dissociation, completed the sustained attention to response task during ganzfeld and control conditions. High dissociative highs made more commission errors during ganzfeld, suggesting increased MW, whereas the other groups displayed the opposite pattern. Increases in commission errors from the control condition to ganzfeld were associated with more alterations in consciousness and negative affect, but only among highs. Sensory homogenization had opposite effects on MW depending on the interaction of hypnotizability and dissociation.     

Simple Discrimination Behavior of Young Chimpanzees: Comparisons with Human Aments and Domestic Animals

The authors' purpose in this paper was to examine how the use of the “sad passive” coping style may be related to adolescent self-reported loneliness. Subjects were asked to complete the revised UCLA Loneliness Scale (Russell, Peplau, & Cutrona, 1980) to determine self-reported loneliness and the Coping with Loneliness Questionnaire (CLQ; Rubenstein & Shaver, 1980) in order to examine coping styles. We hypothesized that those adolescents whose coping strategies fell into the category of sad passivity described by Rubenstein and Shaver would indicate greater loneliness than those adolescents whose coping strategies fell into other categories. Results indicated that sad passivity was used by both lonely and nonlonely adolescents, but that nonlonely youngsters resorted to this method only temporarily and in preparation for a more active coping style. Lonely teens, on the other hand, appeared to remain in the sad-passive mode to a maladaptive degree. These results were discussed in terms of their importance for theories of adolescent loneliness and for possible intervention strategies.
