Effect of Musical Accompaniment on Attitude: The Guitar as a Prop for Persuasion

This study examined the effects on attitude, mood, and recall of embedding a communication in different musical art forms. Subjects listened to four folk songs, each of which either had or did not have guitar accompaniment, and which were either sung or dramatically spoken. Results indicated greater positive emotional arousal and greater persuasion with the presence of guitar accompaniment. The sung-spoken variation had few effects. The results were interpreted as supporting a conclusion of Dabbs and Janis (1965) that a pleasant activity such as eating creates a momentary mood of compliance toward a communication's recommendations. The present study generalized Dabbs and Janis' conclusion to a stimulus situation involving instrumental music. An alternative interpretation that the music inhibited counterargument production was discussed and rejected. The implications of the study for a more general arousal-persuasion model were noted.     

Genes, cognition and dyslexia: learning to read the genome

Studies of dyslexia provide vital insights into the cognitive architecture underpinning both disordered and normal reading. It is well established that inherited factors contribute to dyslexia susceptibility, but only very recently has evidence emerged to implicate specific candidate genes. In this article, we provide an accessible overview of four prominent examples--DYX1C1, KIAA0319, DCDC2 and ROBO1--and discuss their relevance for cognition. In each case correlations have been found between genetic variation and reading impairments, but precise risk variants remain elusive. Although none of these genes is specific to reading-related neuronal circuits, or even to the human brain, they have intriguing roles in neuronal migration or connectivity. Dissection of cognitive mechanisms that subserve reading will ultimately depend on an integrated approach, uniting data from genetic investigations, behavioural studies and neuroimaging.     

A criterion for significant common factor variance

Up to the present only empirical methods have been available for determining the number of factors to be extracted from a matrix of correlations. The problem has been confused by the implicit attitude that a matrix of intercorrelations between psychological variables has a rank which is determinable. A table of residuals always contains error variance and common factor variance. The extraction of successive factors increases the proportion of error variance remaining to common factor variance remaining, and a point is reached where the extraction of more dimensions would contain so much error variance that the common factor variance would be overshadowed. The critical value for this point is determined by probability theory and does not take into account the size of the residuals. Interpretation of the criterion is discussed.     

On a connection between factor analysis and multidimensional unfolding

Given the preference ordering of each of a number of individuals over a set of stimuli, it is proposed that if the preference orderings are generated in a Euclidean space ofr dimensions which can be recovered by unfolding the preference orderings, then a factor analysis of the correlations between individual's preference orderings will yield a space ofr + 1 dimensions with the originalr-space embedded in it, and the additional dimension will be one of social utility. The proposition is clearly shown to be satisfied by means of the Monte Carlo technique for both random and lattice stimuli in three dimensions and for two other examples with random stimuli in one and two dimensions.The preparation of this paper was supported in part by a grant from the National Science Foundation and in part by Project MICHIGAN, a project of the University of Michigan in the field of Combat Surveillance sponsored by the Department of the Army.

Pastoral care through small groups

Summary Pastoral care has for too long been conceived as the task of the ordained clergyman alone. The concept of shared leadership now offers us a unique tool to implement the pastoral care of the whole church—the laity as well as clergy. The small group, as a locus of care and concern and as a training tool, offers a unique way by which this ministry of the laity may become a reality, but training in small group process is vitally important to release this potential.     

Expectancy Accessibility and the Influence of Outcome Expectancies on Adolescent Smokeless Tobacco Use

This study investigated the moderating influence of expectancy accessibility on the relation between outcome expectancies and drug use intentions. Specifically, it was hypothesized that expectancies made temporarily more accessible would predict smokeless tobacco intentions to a greater degree than would less accessible expectancies. In addition, it was anticipated that expectancies regarding positive outcomes of smokeless tobacco use would be better predictors of intention than would expectancies about negative outcomes. Results partially supported the accessibility hypothesis, but this effect occurred for positive outcome expectancies only. In addition, the anticipated prepotency of positive over negative expectancies in predicting drug use intentions was strongly supported. These findings are consistent with theories of problem behavior which differentiate between positive and negative outcome expectancies and which postulate that accessibility of expectancies plays an important role in expectancy-behavior relations.     

The black male urban barbershop as a sex-role socialization setting

Two hundred-eighty participants-as-observer hours and eight hours of informal interviewers with “informants” during a two-month period in summer 1983 were data sources in an analysis of a Black male urban barbershop in a midwestern city. The study focused on the barbershop as a sex-role socialization setting in which adult Black males actively negotiate masculinity while Black male youth passively negotiate masculinity and in all likelihood are socialized to become active negotiators. Content analyses of taped barbershop sessions and the researcher's written reports of the session revealed that the barbershop studied perpetuates sex-role stereotypes, encourages sexist attitudes toward women, and, in general, is a sex-role socialization setting that promotes sex-role inequality.     

Changes in smoking behaviors from late childhood to adolescence: insights from the Canadian National Longitudinal Survey of Children and Youth.

OBJECTIVE: To examine smoking behaviors in Canadian youth from late childhood to adolescence. By following participants from as young as 10 and 11 years, the authors proposed to identify distinct developmental pathways of smoking acquisition. DESIGN: Growth mixture modeling was used to identify developmental trajectories of smoking among 10- to 17-year-old participants of the Canadian National Longitudinal Survey of Children and Youth. MAIN OUTCOME MEASURES: Developmental trajectories of trying smoking, smoking frequency, and smoking intensity. Results: Five developmental trajectories related to smoking frequency were identified, of which 2 were acquisition patterns that led to daily smoking at age 16-17, and 3 were experimentation patterns that led to nonsmoking at age 16-17. The largest variability in changes in smoking behavior over time was the reported level of smoking frequency. CONCLUSION: Analysis showed that there is more than 1 way in which Canadian children and adolescents acquire smoking behaviors over time. The authors were able to differentiate patterns of experimentation from patterns of acquisition. Whereas experimentation has been generally considered as 1 of the stages in the smoking acquisition process leading to regular smoking, these results indicate that experimentation can be described as a distinct process in itself.
