Social and Musical Co-Ordination between Members of a String Quartet: An Exploratory Study

This paper examines the social and musical co-ordination between members of a student string quartet in rehearsal and performance. Devised as an exploratory observation and interview study, a two-tier analysis of the data is undertaken. The first deals with broadly socio-cultural issues, the second with moment-by-moment social and musical co-ordination. The results indicate that there are many factors that influence the functioning of such an ensemble. These include personal concerns about particular social dynamics within the group, performance anxiety worries, as well as immediate musical demands relating to the co-ordination of content and process. The paper concludes with a discussion of ways in which further studies of social and musical co-ordination might be developed. In particular, emphasis is given to the need for the development of a comprehensive theoretical framework reflecting a more adequate conception of music ontology and encapsulating the mutuality of the multi-tier social and musical factors.

Handedness and Musical Ability: A Study of Professional Orchestral Players, Composers, and Choir Members:

The handedness of three groups of accomplished musicians (623 instrumentalists, 331 composers, and 584 choir members) was assessed using a standard questionnaire (Oldfield, 1971). While the three groups of musicians did not differ from one another, there was evidence of a modest, but significant, increase in the proportion of left-handers and mixed-handers among the musicians when compared with a normal population. It was found, for example, that 12-2% of the male and 11-8% of the female musicians were lefthanded as defined by the Laterality Quotient (Oldfield, 1971). These figures compared with 8-5% male and 7 3% female left-handers in their respective age-matched control groups. Further evidence of an increased proportion of left-handed musicians was found for the single item, writing hand. This latter finding suggests that the differences in handedness were not simply a consequence of musical training.

Measuring musical aptitude in children: on the role of age, handedness, scholastic achievement, and socioeconomic status

Scores on the Bentley Measures of Musical Ability test (BMMA) for 897 seven-or eight-year-old children were analysed with respect to a number of factors which previous research suggested might be associated with test performance. Comparisons between the 17 schools participating revealed that the same schools tended to produce either high or low scores. Further analyses revealed a significant relationship between BMMA scores and assessments of school achievement (Standard Attainment Targets - SATs). An association was also present between those schools scoring poorly on the BMMA and those containing relatively large numbers of children receiving subsidised school meals. There was also an association with age. No significant relationship was found, however, between handedness and BMMA scores. The results not only identify some specific limitations of the BMMA, but also point to more general problems in interpreting tests designed to screen for musical ability in children.

Perception of Sex From Complex Body Movement in Young Children

This article reports on a study of the perception of sex from complex body movement. Studies by Cutting and his associates (Barclay, Cutting, & Kozlowski, 1978; Kozlowski & Cutting, 1977) and by Runeson and Frykholm (1983) have shown that adult observers of both adult and child actors (11-12 years old) can reliably recognize the sex of the actor. In this study, prepubescent actors (4-5 years old) were employed, and the role of familiarity of observers with children of this age was also examined. Ten children (4-5 years old), 5 boys and 5 girls, performed 7 actions similar to those employed in Runeson and Frykholms study: walking in a circle, running in a circle, throwing a ball, lifting a box, sitting on the floor, sitting on a chair, and climbing onto a chair and jumping down. Point-light displays were made of each child performing each action. Each actor was recorded performing each action once. An experimental tape was prepared in which all 70 acts from the source tape appeared in a counterbalanced order such that each child appeared once in each block of 10 trials and each action appeared once in each block of 7 trials. The effect of familiarity was explored by employing 3 different groups of observers: the parents of the child actors, a group of adults familiar with children of this age, and a student group of young adults not familiar with children of this age. The overall detection rate was only just above chance and none of the observer groups performed better than chance. Sex was reliably perceived, however, for particular actors and for particular actions. The implications of these findings for Runeson and Frykholms kinematics specifies dynamics principle are noted.

A Q-methodology study of parental understandings of infant immunisation : implications for health-care advice

This study used Q-methodology to explore systematically parental judgements about infant immunisation. A total of 45 parents completed a 31-statement Q-sort. Data were collected after vaccination in general practitioner practices or a private day nursery. Q factor analysis revealed four distinct viewpoints: a duty to immunise based on medical benefits, child-orientated protection based on parental belief, concern and distress and surprise at non-compliance. Additionally, there was a common view among parents that they did not regret immunising their children. Implications of these results are discussed in terms of health-care policy and future research.
