Communication in relationships and adolescent substance use: the influence of parents and friends

This study focused on the openness of communication in teenagers' relationships with mother, father (or parental figure), and closest friend, and its correlation with teenagers' use of cigarettes, alcohol, marijuana, and other drugs. The predictive value for substance use of perceived pressure from friends, friends' substance use, and parents' substance use was also analyzed. The findings from questionnaires and interviews conducted with 37 students at an urban and a suburban/rural high school in New England are reported. The results suggest that the degree to which adolescents talk openly with their parents may influence the extent of their substance use. The presence of at least one "open" parental figure was associated with lower levels of all substance use. However, there was no evidence that openness with a close friend or perceived pressure from friends is related to substance use.     

The Independence of Practical Ethics

After criticizing three common conceptions of therelationship between practical ethics and ethical theory, analternative modeled on Aristotle's conception of the relationshipbetween rhetoric and philosophical ethics is explored. Thisaccount is unique in that it neither denigrates the project ofsearching for an adequate comprehensive ethical theory norsubordinates practical ethics to that project. Because the purpose of practical ethics, on this view, is tosecure the cooperation of other persons in a way that respectstheir status as free and equal, it seeks to influence thejudgments of others by providing them with reasons that areaccessible to their own understanding. On this account, theindependence of practical ethics is rooted in an appreciation ofthe constraints that non-ideal circumstances place on the rolethat the philosophically refined premises of moral theory canplay in such public deliberations. Practical and philosophicalethics are united, not by shared theoretical frameworks orprinciples, but by the need to exercise intelligently the sameintellectual and affective capacities. They are separated, notby the particularity or generality of their starting points, butby their responsiveness to the practical problem of facilitatingsound normative deliberations among persons as we find them,under non-ideal circumstances.     

Rhythm histograms and musical meter: A corpus study of Malian percussion music

Studies of musical corpora have given empirical grounding to the various features that characterize particular musical styles and genres. Palmer & Krumhansl (1990) found that in Western classical music the likeliest places for a note to occur are the most strongly accented beats in a measure, and this was also found in subsequent studies using both Western classical and folk music corpora (Huron & Ommen, 2006; Temperley, 2010). We present a rhythmic analysis of a corpus of 15 performances of percussion music from Bamako, Mali. In our corpus, the relative frequency of note onsets in a given metrical position does not correspond to patterns of metrical accent, though there is a stable relationship between onset frequency and metrical position. The implications of this non-congruence between simple statistical likelihood and metrical structure for the ways in which meter and metrical accent may be learned and understood are discussed, along with importance of cross-cultural studies for psychological research.     

Children's attention to beliefs in interactive persuasion tasks

Whether and when children can apply their developing understanding of belief to persuasion was examined using interactive puppet tasks. Children selected 1 of 2 arguments to persuade a puppet to do something (e.g., pet a dog) after hearing the puppet's belief (e.g., "I think puppies bite"). Across 2 studies, 132 children (ages 3-7 years) engaged in these persuasion tasks and in false-belief reasoning tasks, presented in puppet and story formats. Belief-relevant argument selection increased with age, as did appropriate reasoning about false beliefs, and occurred more in puppet than story tasks. Results suggest that improvements in belief reasoning in early childhood may be reflected in social interactions such as persuasion.     

Effects of Differential Instructions and Anxiety Level on Discrimination Learning

Seventy-seven nonconserver-conserver dyads and 53 nonconserver-nonconserver dyads were given a conservation of length task which encouraged conflicting judgments from the nonconserving dyad. Ss were boys and girls aged 4 through 8. Control tasks for social dominance/compliance were also administered. All sessions were videotaped. The nonconserver-nonconserver dyads did not tend to produce the correct answer by perspective coordination and showed little posttest gain. Nonconservers who had been paired with conservers showed posttest gain on length, mass, liquid, and number conservation problems. Being the winner of an interaction session was associated with opposing the partner's judgment and with producing justifications in conserver-nonconserver dyads, but only with social compliance in nonconserver-nonconserver dyads. Justifications in support of conservation judgments were invariably by logical principles but very rarely so in support of nonconservation judgments. The results are discussed in terms of the relative importance of cognitive conflict and transmission as crucial social experiences in cognitive development, and in terms of the possibility that nonconservers may lack the notion of objective correctness relative to conservers.     

Perception–production relationships and phase correction in synchronization with two-interval rhythms

Two experiments investigated the effects of interval duration ratio on perception of local timing perturbations, accuracy of rhythm production, and phase correction in musicians listening to or tapping in synchrony with cyclically repeated auditory two-interval rhythms. Ratios ranged from simple (1:2) to complex (7:11, 5:13), and from small (5:13 = 0.38) to large (6:7 = 0.86). Rhythm production and perception exhibited similar ratio-dependent biases: rhythms with small ratios were produced with increased ratios, and timing perturbations in these rhythms tended to be harder to detect when they locally increased the ratio than when they reduced it. The opposite held for rhythms with large ratios. This demonstrates a close relation between rhythm perception and production. Unexpectedly, however, the neutral “attractor” was not the simplest ratio (1:2 = 0.50) but a complex ratio near 4:7 (= 0.57). Phase correction in response to perturbations was generally rapid and did not show the ratio-dependent biases observed in rhythm perception and production. Thus, phase correction operates efficiently and autonomously even in synchronization with rhythms exhibiting complex interval ratios.     

Self-esteem and job complexity as moderators of performance and satisfaction

Self-esteem and job complexity were investigated as moderators of self, supervisor, and peer ratings of performance and satisfaction with work, supervisors, and peers testing balance and activation theories. One hundred and fifty-three registered nurses served as subjects. Measured self-esteem was not significantly related to the performance or satisfaction measures. Rather, the important variable was perceived job complexity as predicted by Scott's activation theory. Self-ratings of performance and satisfaction with work and peers were greatest at optimal complexity with lower values at high and low complexity. Some support was found for self-esteem as a moderator of the relationship between performance and satisfaction measures in line with Korman's formulations.     

Coping Effectiveness: A Path Analysis of Self-Efficacy,Control, Coping,and Performance in Sport Competitions1

We examined a model of coping effectiveness based on Lazarus and Folkman's (1984) stress and coping theory and Bandura's (1986) social cognitive theory. Female athletes (n= 178) aged 16 to 28 were studied over two rounds of a sport event. Path analysis (LISREL VI) revealed that higher levels of self-efficacy and control appraisals were associated with better performance. As expected, performance and performance satisfaction in Round 1 influenced appraisals and coping during the second performance. In addition, control appraisal was associated with disengagement coping, and both engagement and disengagement coping were related to performance and performance satisfaction. Self-efficacy mediated the performance/control relationship for Round 1, but not the performance satisfaction relationship.
