Measuring violence on television

Television violence has been measured in numerous studies. However the amounts reported vary considerably depending on the definitions provided of violence and the sampling periods adopted. Studies that have followed the methodology of Gerbner are more easily compared and point to rates of around 5-6 violents acts per hour on prime time television in most countries. The rate of violence on British television is considerably lower than this and evidence points to a recent decline. However, traditional content analyses are limited and provide little understanding of television as a narrative art.     

Systemic change in limited family therapy

Some families present with so many problems and disordered family processes that where and how to begin is an extremely important question. When premature termination of therapy also appears likely, a family therapist may simply attempt to initiate a structural change within the family system so that the family can continue on its own. This article describes the responses of a highly chaotic family to such a single therapeutic intent.     

Gender and developmental differences in children's conversations

Extending work on childhood gender differences by J. Block (“Assimilation, Accommodation and the Dynamics of Personality Development,” Child Development, 1982, 53, 281–295) and J. H. Block (“Differential Premises Arising from Differential Socialization of the Sexes: Some Conjunctures,” Child Development, 1983, 54, 1335–1354), the present research investigated assimilative and accommodative discourse devices in the speech of 24 preschool children (12 boys and 12 girls) and 24 middle-childhood youngsters (12 boys and 12 girls) in each of grades 3 and 6. Boys' discourse, regardless of age, contained more accommodative devices. Girls' discourse, regardless of age, contained more assimilative devices. Age effects were apparent; older children, regardless of gender, used more discourse devices of both kinds than younger children.     

Effects of duration and activity during the post-KR interval on motor learning

Summary The present experiment assessed a traditional assumption regarding the informational role of knowledge of results (KR) in motor learning. The assumption is that learning is facilitated to the degree that KR is used to reduce goal-directed error. To test the assumption we examined two specific predictions that have been made with respect to post-KR interval effects: that the interval should be long enough for action-planning operations to occur and that the interval be free from interpolated activities that might prevent action-planning operations. The present study used a factorial arrangement of post-KR interval durations and interpolated activities during the post-KR interval to test these predictions. Using a movement timing task, we found that, contrary to predictions, learning was not facilitated by lengthening the post-KR interval. Also, in opposition to existing theory, the data revealed that interpolated activities, when combined with longer post-KR durations, were not detrimental to learning and actually improved learning in some instances. These findings are discussed together with recent evidence regarding various KR effects that suggest that many theoretical assumptions about the role of KR need revision.     

Parametric and bootstrap approaches to repeated measures designs

Recently, a nonparametric technique called bootstrapping has been recommended over the more well-known analysis of variance (ANOVA) for analyzing repeated measures data. Advocates cite as bootstrap’s advantages over ANOVA the fact that the former uses distributional information and is free of normal theory assumptions. The present study used a computer simulation to compare the two techniques calculated using data sampled from normal and nonnormal distributions. The parametric test had adequate control of Type I error rates; the nonparametric test had overly liberal Type I error rates and therefore is not recommended.     

Diurnal variation in the Positive Affects

We examined the circadian rhythm of two basic dimensions of mood—Positive Affect (PA) and Negative Affect (NA). Subjects were 196 college students in two studies who completed a mood rating form approximately seven times a day for 1 week. Significant diurnal variation was found to exist in overall Positive Affect, and in four component content areas, but not in Negative Affect. Specifically, all components of PA rose sharply from early morning until noon, remained relatively constant until 9 p.m., and then fell rapidly. The rise and fall of PA were quite robust across subjects, but the apparently static level of PA from noon to 9 p.m. was shown to result from averaging across marked individual differences in the time of peak PA. Various potential sources of these individual differences—“morningness-eveningness,” introversion-extraversion, and neuroticism/dysphoria—were investigated. Neither of the personality variables accounted for the significant variation in diurnal mood patterning, but clearly defined morning and evening types did show different patterns. Possible links between the mood pattern obtained and biologically based circadian rhythms, which have been postulated to be dysregulated in depression and mania, are discussed.
