A perceptual investigation of polytonality

Summary Four experiments investigated the perception of tonal structure in polytonal music. The experiments used musical excerpts in which the upper stave of the music suggested a different key than the lower stave. In Experiment 1, listeners rated the goodness of fit of probe tones following an excerpt from Dubois's Circus. Results suggested that listeners were sensitive to two keys, and weighted them according to their perceived importance within the excerpt. Experiment 2 confirmed that music within each stave reliably conveyed key structure on its own. In Experiment 3, listeners rated probe tones following an excerpt from Milhaud's Sonata No. 1 for Piano, in which different keys were conveyed in widely separate pitch registers. Ratings were collected across three octaves. Listeners did not associate each key with a specific register. Rather, ratings for all three octave registers reflected only the key associated with the upper stave. Experiment 4 confirmed that the music within each stave reliably conveyed key structure on its own. It is suggested that when one key predominates in a polytonal context, other keys may not contribute to the overall perceived tonal structure. The influence of long-term knowledge and immediate context on the perception of tonal structure in polytonal music is discussed.     

Taking on the roles of educator and mediator: Two means of preventing ethical conflicts for community psychologists when financial resources are scarce

Three approaches are presented in this commentary on ethical conflicts in the practice of community psychology. The first is the prevention of such conflicts, in contrast with ways in which conflicts can be coped with or resolved. The second is a re-examination of the roles of the community psychologist, and of how a modification of these roles could reduce the likelihood that ethical conflicts would arise. And, finally, a more general problem is pointed out concerning the fact that communities do not generate funds sufficient to meet the needs of their citizens. Community psychologists are drawn into ethical conflicts revolving around the allocation of funds if and when these conditions prevail.     

Absolute and relative pitch: Global versus local processing of chords

Absolute pitch (AP) is the ability to identify or produce notes without any reference note. An ongoing debate exists regarding the benefits or disadvantages of AP in processing music. One of the main issues in this context is whether the categorical perception of pitch in AP possessors may interfere in processing tasks requiring relative pitch (RP). Previous studies, focusing mainly on melodic and interval perception, have obtained inconsistent results. The aim of the present study was to examine the effect of AP and RP separately, using isolated chords. Seventy-three musicians were categorized into four groups of high and low AP and RP, and were tested on two tasks: identifying chord types (Task 1), and identifying a single note within a chord (Task 2). A main effect of RP on Task 1 and an interaction between AP and RP in reaction times were found. On Task 2 main effects of AP and RP, and an interaction were found, with highest performance in participants with both high AP and RP. Results suggest that AP and RP should be regarded as two different abilities, and that AP may slow down reaction times for tasks requiring global processing.     

Reasoning Through Instructional Analogies

This article aims to account for students’ assessments of the plausibility and applicability of analogical explanations, and individual differences in these assessments, by analyzing properties of students’ underlying knowledge systems. We developed a model of explanation and change in explanation focusing on knowledge elements that provide a sense of satisfaction to those judging the explanation. We call these elements “explanatory primitives.” In this model, explanations are accepted or rejected on the basis of (a) the individual's convictions concerning particular explanatory primitives and (b) the fit of these primitives to current circumstances. Data are drawn from clinical interviews with three high school students who worked through a bridging analogies tutoring sequence on the existence of the normal force in mechanics. Methodologically, our work involves fine-grain analysis of process data and explicit principles of empirical accountability; we believe it marks a methodological advance over most previously reported empirical studies of analogical reasoning.     

Naming difficulties in adolescents with dyslexia: application of the tip-of-the-tongue paradigm

The present study used the "tip-of-the-tongue" (TOT) experimental paradigm in a picture-naming task to explore the naming deficits of adolescents with dyslexia. As compared with a control group of typically developing readers, the adolescents with dyslexia had fewer correct responses and more TOT responses. When they failed to retrieve a target word, the adolescents with dyslexia had more phonological substitutions and benefited less from a phonological cue. However, both groups did not differ in the amount of semantic substitutions and supplied the same amount and kind of partial semantic information on the missing target word. These findings suggest that adolescents with dyslexia have significant naming difficulties that seem to arise because of difficulty in accessing the phonological word forms after the corresponding abstract lexical representation has been successfully accessed.     

Physical Attractiveness and Psychological Adjustment Among Substance Abuse Inpatients: A Longitudinal Study1

Relations between psychological adjustment and physical attractiveness were examined longitudinally in substance abuse inpatients, controlling for the effects of length of drug abuse, length of inpatient stay, age, and socioeconomic status. Measures of adjustment and attractiveness were obtained during the first week of admission and six weeks later (within two weeks of discharge). Regression analyses indicated that initial attractiveness did not predict later adjustment, and initial adjustment did not predict later attractiveness. Partial correlation analyses revealed a positive association between attractiveness and adjustment at the first time point, but not at the later time point. These results suggest that physical attractiveness exerts only a temporary effect on judgments of adjustment in an inpatient setting. Attractiveness may affect decisions made when screening patients at mental health facilities, but may not affect decisions made over the full course of inpatient treatment.     

Ethnic, gender, and socioeconomic differences in young adults' self-disclosure: who discloses what and to whom?

Self-disclosure of feelings, thoughts, experiences, and beliefs is central to our lives as social beings and has numerous implications for relationships and health. Although prior research suggests that men and underrepresented groups disclose less, ethnicity is conflated with socioeconomic status and there are few data regarding the types of information that different groups disclose and whether this information is disclosed equally to different people. The current study measured self-disclosure in 203 young adults (50% African American, 50% female), in respect of seven domains and 10 interpersonal targets. As expected, disclosure was not lower among African Americans once income was controlled, although both ethnicity and gender interacted with domain of disclosure and interpersonal target. Importantly, young men and African Americans reported disclosing less in the context of more intimate relationships. Together, these results suggest that income may be as important in predicting low disclosure as ethnicity or gender and that lower disclosure in low-disclosing groups is particularly evident in intimate relationships. Results are discussed in terms of their implications for patterns of interpersonal relating and physical and mental health processes.     

Children's Level of Participation in a False-Belief Task,Age, and Theory of Mind

The hide-and-seek deception task of M. Chandler, A. S. Fritz, and S. Hala (1989) was modified to provide a more precise estimate of the age at which children acquire and manifest a theory of mind. Two characters (good, bad) and two levels of involvement (pretend play, sociodramatic play) were incorporated into the research design, so that children's representational understanding of deception could be studied. Two-, 3-, and 4-year-olds (N = 90) participated in the study. The results indicated that 4-year-olds used significantly more deceptive strategies than 2- and 3-year-olds in pretend play and in sociodramatic play. There was no difference between 2- and 3-year-olds in the use of deceptive strategies; they used significantly fewer strategies in the bad roles than in the good roles. No significant differences were found in the 3 age groups' performances in the good-character tasks. The reality-masking hypothesis (P. Mitchell, 1994) accounts for the differences in performances on that task; thus, children younger than 4 years old do seem to have a theory of mind.     

The Effectiveness of Brief Versus Intermediate Duration Psychodynamic Psychotherapy in the Treatment of Adjustment Disorder

Treatment studies and particularly psychotherapeutic treatment studies of patients suffering from an adjustment disorder are very scarce, leading to insufficient evidence regarding the efficacy of treatment in this population. Whereas timely psychotherapy is known to be of benefit in the treatment of adjustment disorders, the ideal duration of psychotherapeutic interventions is not known. This study examined whether a brief 12-session focused psychodynamic psychotherapy may be as efficient as a longer intermediate-term (1?year) psychodynamic psychotherapy in treating patients suffering from an adjustment disorder. Subjects (n?=?66) were randomly assigned to either brief or intermediate psychotherapy. They were assessed by self-report measures and clinician’s evaluation at baseline, end of therapy, and 9?months after therapy was terminated. The results showed a good overall improvement in the whole group. Furthermore, brief psychotherapy was found to be as good as intermediate psychotherapy both at the end of treatment and at follow-up. Although our study was not designed to confirm the efficacy of dynamic psychotherapy in the treatment of adjustment disorders, our results suggest that brief interventions may be good enough in adjustment disorder, thus allowing treatment of a greater number of patients without compromising for the quality and suitability of treatment.
