Social cognitive processes mediating the relationship between exposure to television's sexual content and adolescents' sexual behavior

This study used multiple-group structural equation modeling to test a model explaining the association between exposure to televised sexual content and initiation of intercourse among an ethnically diverse national sample of 1,292 adolescents. The authors hypothesized, on the basis of social-cognitive theory, that exposure to televised sexual content would influence adolescents' safe-sex self-efficacy, sex-related outcome expectancies, and perceived peer norms regarding sex, and that each of these would, in turn, influence intercourse initiation. Findings support a model in which the relationship between exposure to TV's sexual content and intercourse initiation is mediated by safe-sex self-efficacy among African Americans and Whites but not among Hispanics. Outcome expectancies and perceived peer norms may also mediate the link between exposure and intercourse initiation among all 3 racial/ethnic groups, although evidence of this could not be confirmed.     

Exact and resampling probability values for weighted kappa

Permutation procedures to compute exact and resampling probability values for weighted kappa are described. Comparisons with asymptotic probability values demonstrate that exact permutation procedures are advantageous for sparse data sets, whereas resampling permutation procedures are appropriate for both sparse and nonsparse data sets.     

Acquisition and extinction of a simple motor skill as a function of delay of knowledge of results

The present experiment demonstrates that the effects of delay of knowledge of results (KR) in a line drawing task depend upon the dependent variable which is considered and the original response tendency of the subjects. Delay of KR interfered with the acquisition of the correct response when number of correct responses is the dependent variable. When KR was omitted the immediate-KR group continued to make more correct responses than the delayed-KR group. However, there was a significant reduction in correct responses for both groups. When absolute error was the response measure there were no significant differences between immediate-and delayed-KR groups either during acquisition or extinction. Analysis of the type of response made during extinction suggested that the overshooting effect obtained by previous investigators may be typical of short responders trained under conditions of immediate reinforcement but not of those trained under delayed-KR.

Greenspoon and Foreman (1956) obtained clear cut evidence that the effectiveness of knowledge of results (KR) in a line drawing task varies inversely with the time delay between the response and KR. On the other hand, Bilodeau and Bilodeau (1958) were unable to demonstrate a similar effect in five different experiments. Bilodeau and Ryan (1960) hypothesized that the Greenspoon and Foreman findings could not be replicated and they did in fact obtain null results. However, Dyal (1965) has recently replicated the Greenspoon and Foreman results for the case of a 30 sec. delay interval.

The purpose of the present experiment is twofold: (a) to provide replication of Green-spoon and Foreman's study at the 20 sec. delay interval used by Bilodeau and Ryan, and (b) to determine the effect of elimination of KR on a simple motor response which has been formed on the basis of KR.     

Acculturation Attitudes in Plural Societies

Dans les sociétés culturellement diversifiés, les individus peuvent présenter des attitudes relatives à leurs relations avec les autres et les groupes. Ces attitudes (dites "attitudes d'acculturation") sont liées à des prises de position sur deux problèmes généraux posés à toute personne en acculturation: la préservation culturelle de son propre groupe et le contact avec les autres groupes. On définit les attitudes d'assimilation, d'intégration, de séparation et de marginalisation, puis on les mesure dans plusieurs groupes en acculturation d'Australie et du Canada (les indigènes, les immigrants et les groupes ethniques implantés). On donne la validité et la fidélité des échelles d'attitude, puis on analyse les relations des échelles entre elles par rapport aux deux problèmes sous-jacents que sont la préservation et le contact. Enfin, quelques-unes des applications pratiques des attitudes d'acculturation sont envisagées.     

Mood and sleep in aging women

The possible covariations of mood and sleep was examined in a group of 25 normal, aging women. Mood assessments made in the evenings of 3 consecutive days were independently related to both before and after sleep night. Only two sleep variables: sleep efficiency and latency to first rapid eye movement (REM) period--were reliably related to daytime moods. The relative paucity of relation between mood and sleep variables was interpreted as reflecting a general insulation of sleep from day-to-day mood variations.     

DIRECTORY OF CROSS-CULTURAL PSYCHOLOGICAL RESEARCH

The original Directory, which was published in this Journal (1968, 3, 137–148), has proved to be of value to many psychologists already engaged in, or wishing to begin, cross-cultural research. During the year, a number of persons have written, requesting to be included in an annual supplement, and others have indicated changes of address. This supplement provides the details of both, with a first section listing additions and a second one providing changes of address. Once again, may I invite those wishing to be included in the Directory, to write to me in time for next year's annual supplement ?     

How shall we all live together?: Meta-analytical review of the mutual intercultural relations in plural societies project

Living together in culturally plural societies poses numerous challenges for members of ethnocultural groups and for the larger society. An important goal of these societies is to achieve positive intercultural relations among all their peoples. Successful management of these relations depends on many factors including a research-based understanding of the historical, political, economic, religious and psychological features of the groups that are in contact. The core question is ‘how we shall we all live together?’ In the project reported in this paper (Mutual Intercultural Relations in Plural Societies; MIRIPS), we seek to provide such research by reviewing three core psychological hypotheses of intercultural relations (multiculturalism, contact and integration) in 21 culturally plural societies. The main goal of the project is to evaluate these hypotheses across societies within the MIRIPS project in order to identify if there are some basic psychological principles that underlie intercultural relations panculturally. If there are, the eventual goal is to employ the findings to propose some policies and programmes that may improve the quality of intercultural relationship globally. An internal meta-analysis using the MIRIPS project data showed that the empirical findings from these societies generally support the validity of the three hypotheses. Implications for the development of policies and programmes to enhance the quality of intercultural relations are discussed.     

Metacognitive experience and transfer of logical reasoning

The experiments examine the influence of metacognitive experience on the transfer of logical processes in a problem solving setting. Subjects were presented with two versions of Wason's (1966) selection task. Although they were able to perform successfully on the concrete tasks (following a minimal explanation of the correct solution on an initial trial), the majority were not able to transfer a successful method to the abstract tasks. Verbalization during, or following, the concrete tasks produced substantial transfer effects however. It is suggested that verbalization may lead to an increased awareness of past behaviour, particularly of those aspects necessary for successful solution.
