Irrelevance of mitigating circumstances in retaliatory behavior at high levels of excitation

Subjects were aggressively instigated by a provoker. They then performed either a nonstrenuous or a strenuous task in order to be placed in either a moderate or an extreme state of sympathetic arousal. Following the task, they either learned or did not learn about mitigating circumstances behind the provoker's behavior. This information was received prior to the provision of an opportunity to retaliate. Under conditions of moderate arousal, mitigating circumstances were found to reduce retaliation. In contrast, these circumstances failed to exert any appreciable effect on retaliation under conditions of extreme arousal. In addition, the induction of extreme arousal was observed to increase retaliatory behavior. The findings were considered to support a model of hostility and aggression that postulates a specific interdependency of cognitive and excitatory processes.     

Socialization and career orientation among black and white college women

In a study of career orientation among black and white college women, support was found for hypotheses derived from postulates of Rotter's Social Learning Theory. Compared to whites, (1) blacks were less likely to expect the level of work involvement preferred; (2) blacks expected more employment; and (3) blacks were more likely to prefer less employment than they realistically expected. Antecedents of career expectation were categorized as internal, external, or neutral. As hypothesized, variables expressive of external control predicted level of career expectation among blacks, whereas variables expressive of internal control predicted high career expectations among whites.     

The portrayal of men and women in U.S. television commercials: A recent content analysis and trends over 15 years

This article summarizes the content analyses of male and female portrayals in U.S. television commercials that have been published since 1971. The paper also includes the results of a content analysis of television commercials conducted on a 1985 sample. Where possible, the data from the present study are compared to the findings of previous research to illustrate trends over time. The results reveal several differences between the portrayal of men and women, but many of the gaps seem to be narrowing. Men and women now appear equally often as central characters in prime-time commercials. Although a prior study indicated a difference between male and female primary characters' use of arguments, the present data revealed no differences in this regard. A lower percentage of female than of male central characters are depicted as employed, but males are being presented in increasing numbers as spouses and parents, with no other apparent occupation. Women are still more likely than men to be seen in domestic settings, advertising products used in the home. Although the difference seems to have become smaller, women are more likely than men to be shown as users of the products they advertise. The most striking gap persists with regard to narrators. Consistent with other content analyses conducted over the past 15 years, approximately 90% of all narrators are male. The findings are discussed in terms of the potential effect of exposure to stereotyped depictions on viewers' sex role attitudes.     

Semantic processing in dichotic listening? A replication

This experiment explores semantic processing of one message while another is attended to and shadowed. It was an attempt to replicate and clarify an earlier finding by Lewis (1970). Like Lewis, we found that mean shadowing latency was increased when a synonym of the shadowed word coincided with it on the unattended channel. However, this occurred only with synonyms in an early list position and appeared to affect only a small proportion of trials. The implications of this and other recent findings for theories of selective listening are discussed.     

MULTIPLE TREATMENT INTERFERENCE IN THE ALTERNATING TREATMENTS DESIGN AS A FUNCTION OF THE INTERCOMPONENT INTERVAL LENGTH

In experimental designs requiring the administration of more than one treatment to the same subject(s), the effect of one treatment may be influenced by the effect of another treatment (Campbell & Stanley, 1963), a phenomenon known as multiple treatment interference. We conducted two studies in which multiple treatment interference in an alternating treatments design was shown to be a function of the length of the intercomponent interval (ICI) separating treatment conditions. In the first study, we evaluated the effects of four different treatments on the mouthing of a severely retarded boy. Under a 1-min ICI no consistent differential responding to treatment was obtained. Differential responding emerged when the ICI was increased from 1 min to 120 min, thus suggesting multiple treatment interference in the lack of differential responding under a 1-min changeover interval. Functional control of the nondifferential and differential responding as a function of the ICI length was replicated in a reversal phase. In the second study, we compared two treatment procedures for the disruptive noncompliant behavior of a moderately retarded boy. Multiple treatment interference (i.e., the lack of differential responding) occurred with the 1-min intercomponent interval. An increase to a 120-min ICI again resulted in differential responding. A replication of multiple treatment interference by a reversal to a short interval phase was not achieved in the second subject. Results of this study support much of the basic literature on discrimination and multiple treatment interference. Major findings of this study are twofold: Multiple treatment interference can depend on the length of the changeover interval between treatments and multiple treatment interference can take the form of a lack of differential responding to various treatments. Implications for future research are discussed.
