EEG alpha desynchronization in musicians and nonmusicians in response to changes in melody, tempo, and key in classical music

Two experiments were performed to examine musicians' and nonmusicians' electroencephalographic (EEG) responses to changes in major dimensions (tempo, melody, and key) of classical music. In Exp. 1, 12 nonmusicians' and 12 musicians' EEGs during melody and tempo changes in classical music showed more alpha desynchronization in the left hemisphere (F3) for changes in tempo than in the right. For melody, the nonmusicians were more right-sided (F4) than left in activation, and musicians showed no left-right differences. In Exp. 2, 18 musicians' and 18 nonmusicians' EEG after a key change in classical music showed that distant key changes elicited more right frontal (F4) alpha desynchronization than left. Musicians showed more reaction to key changes than nonmusicians and instructions to attend to key changes had no significant effect. Classical music, given its well-defined structure, offers a unique set of stimuli to study the brain. Results support the concept of hierarchical modularity in music processing that may be automatic.     

Comparison of the RT3 Research Tracker and Tritrac R3D accelerometers

This study compared the RT3 Research Tracker accelerometer to the Tritrac R3D accelerometer in both laboratory and field settings and tested the hypothesis that the RT3 records higher physical activity counts and smaller standard deviations than the R3D. The RT3 is relatively new and untested and its concurrent validity with existing instruments and physical activity needs to be assessed before being used in research. In this study the RT3 had higher average recordings of physical activity counts in all of the nine testing situations than the R3D. However, in terms of agreement between the instruments, the RT3 might be 582 below or 1,236 above (activity counts) the R3D in assessing physical activity. These results do not establish that the RT3 is more consistently measuring higher physical activity counts than the R3D. Comparing vector magnitude with oxygen consumption and heart rate across the 0% grade testing conditions indicated that the RT3 and R3D are sensitive to changes in various intensities of level ambulation. When the 5%, 10%, and 15% grade on the treadmill protocols were analyzed, low correlations between oxygen consumption and heart rate with vector magnitude responses were found for both the RT3 and R3D. Differences in agreement between the RT3 and R3D did not vary in any systematic way over the range in testing conditions which substantiates that the RT3 and R3D accelerometers are sensitive on flat surfaces but are insensitive to changes in grade.     

Significance of violence in stories of young children

Stories told by 72 5-yr.-old children were scored for themes of violence and correlated with their mothers' reports of aggressive or fearful behaviors. Values for the entire sample were not significant. However, when data for Hispanic children were removed from the sample the correlation of violent stories to ratings of children's aggression was significant (r = .27) and for a count of violent words r = .30. The correlation of violent words to fearfulness was .28 and for girls only .35. The count of violent words was also correlated with African-American children's ratings of fearfulness (r = .64).     

The Efficacy of an Integrated Theoretical Approach to Group Psychotherapy for Male Inmates

To assess the efficacy of an interpersonal process-oriented and cognitive-behavioral group psychotherapy program, 36 incarcerated male adults were assigned to either a treatment group (n = 20) or a no treatment control group (n = 16). Outcome measures consisted of paper-pencil self-report instruments, institutional behavioral data, and structured interviews with the group therapists (n = 3). Results indicated no significant changes in inmates' level of defensiveness, empathy, or institutional behavior; however, the inmates reported universally positive reactions to the treatment program. The group therapists also perceived the treatment program as efficacious, particularly in fostering a cohesive group atmosphere and increasing inmate responsibility for group leadership. Implications for practice and research are discussed.     

'In sickness and in health': the development of alternative discourses in work with families with parental illness

This paper outlines the development of clinical understanding and a clinical model for working with families with parental physical illness. The lens of gender to explore clinical process reveals blind spots and can uncover alternative perspectives on parental illness. The authors look at the very different needs of children and parents for coherent explanations. The impact of this way of working on therapists and the importance of reflecting teams, as part of the process of working collaboratively with families, are addressed.     

Practical Considerations and Alternative Research Methods for Evaluating HR Programs

Program evaluation methods capitalizing on quasi-experimental designs are introduced as useful alternatives for evaluating human resources (HR) programs such as selection systems, training courses, performance measurement systems, and 360 degree feedback. A case study is presented to illustrate the benefits of program evaluation methods for evaluating HR programs. In addition, several post-hoc considerations that often moderate results from HR evaluations are described. It is suggested that when these considerations are addressed, quasi-experimental program evaluation methods provide a promising tool for demonstrating bottom line impact of HR initiatives.     

Counselling adults who were abused as children: Clients' perceptions of efficacy, client-counsellor communication, and dissatisfaction

Despite the amount of clinical material relating to adults who were abused as children, there is a dearth of research which has examined the effectiveness of counselling such clients. In order to examine the perceived efficacy of counselling with this client group, a total of 53 in-depth interviews were undertaken with a sample that included adults abused as children who had received counselling, counsellors working with this client group, and counselors-who-were-abused-as-children. The findings indicate that there are many similarities in what abused clients and the general client population judged to be helpful and unhelpful factors in counselling. However, certain aspects of the counsellor-client relationship appear to have specific impacts and meaning for an abused client group, especially when they have little prior knowledge or experience of counselling. Data are presented relating to clients' evaluations of counselling. These illustrate clinically relevant issues in relation to communication and experiences of dissatisfaction. One conclusion from the study is that in terms of their responses to counselling, it is simplistic for adults who were abused as children to be categorisied as a unitary group. Nevertheless, there are certain aspects of counselling with such clients which do merit particular attention if practitioners are to minimise the possibility of counselling being ineffective, unhelpful or, at worst, re-traumarising.     

Effects of computer interfaces on computer-based statistical analysis

Thirty-one first-year psychology graduate students in a computer applications course completed a set of structured problems, unstructured problems, and data-screening problems in each of two statistical computing environments: a menu-based interface (SPSS for Windows) and a traditional command-based interface (SPSSx). Performance on the menu-based interface was generally superior to performance on the command-based interface. More of the structured problems were completed successfully within the menu-based interface. The menu-based interface also facilitated error identification, was rated as easier to use, and was preferred nearly 4 to 1 over the command-based interface. For the unstructured problems, students identified more relationships in the data set and issued more statistical commands when working with the menu-based interface. These findings are consistent with the interpretation that because the menu-based interface requires fewer mental resources to be dedicated to the mechanics of analysis, more resources are available to devote to higher level problem solving.
