This meta-analysis examined the impact of a mother's decision to disclose her HIV positive serostatus to her children. Results indicated that disclosure to a child improves the parent-child relationship (average r = + 0.171). There was a corresponding increase in internalized negative emotions (average r = + 0.108) and negative externalized…

Analyzes manuscripts that have studied the treatment of communication apprehension. Concludes that all forms of treatment (cognitive modification, systematic desensitization, and skills training) were effective in reducing public speaking anxiety and that the type of self-report scale did not affect the observed effect size. (MS)

Describes a meta-analysis comparing the persuasiveness of one-sided and two-sided messages. Demonstrates that a two-sided message with refutation is more persuasive than a one-sided message, whereas a one-sided message is more persuasive than a two-sided message without refutation. (SR)

Conducts a meta-analysis of 23 manuscripts containing information on 30 experiments that examined communication apprehension and cognitive performance. Finds a statistically significant negative correlation between communication apprehension and cognitive performance. (MG)

A meta-analysis explored the association between past studies on intercultural communication effectiveness and intercultural communication competence, and examined the relationship between knowledge-based and skill-based attributes in predicting intercultural communication competence. A total of 16 studies met the criteria of having recoverable…

Examines by meta-analysis the effect that exposure to pornography produces on aggressive behavior under laboratory conditions considering a variety of possible moderating conditions. Demonstrates a homogeneous set of results showing that pictorial nudity reduces subsequent violent behavior, but that depictions of nonviolent sexual behavior and…

Sex differences in language use have been examined for many years, but no clear-cut conclusions exist. A meta-analysis of the existing literature was conducted regarding powerful/powerless language use, including 30 studies, with a total combined sample size of 3,012. The overall correlation indicated that men use more powerful language than…

Uses meta-analysis to test three models of the "sleeper" effect (a theory proposing that in the long term low credible sources may actually attain greater attitude change in message recipients than high credible sources). Concludes that the sleeper effect does exist, and offers suggestions for practitioners and theorists. (SR)

Compares the persuasiveness of using statistical versus narrative evidence (case studies or examples) across 15 investigations. Indicates that when comparing messages, statistical evidence is more persuasive than narrative evidence. (PA)

A study quantitatively summarized the literature examining the association between acceptance of rape myths and exposure to pornography to address disputes in the academic community regarding the consistency of such research. The entire collection of "Psychological Abstracts" and "Sociological Abstracts" was manually searched…

Reports on meta-analysis of 183 experiments comparing the effect sizes (average amount of change observed) of measurement techniques for assessing the effectiveness of public speaking anxiety treatments. Shows differences between self-report, observer, and physiological measurement techniques. Finds no interaction between type of therapy and type…

A study extended the work of M. Allen and R. Preiss (1990) that analyzed the issues in public speaking textbooks and the level of accuracy with which scientific information is represented. A total score analysis of 112 textbooks showed no significant improvement in the accuracy of textbooks over time or with new editions. Findings of the…

Examines the relationship between teaching and research. Considers whether an emphasis on one or the other better serves the interests of communications departments. Adumbrates arguments suggesting that research undermines teaching and those suggesting the converse. Shares the results of a meta-analysis of existing research on the topic. Finds a…

Uses the results of meta-analyses examining the effects of various message design strategies to evaluate public speaking and persuasion textbooks. Compares the conclusions of the meta-analyses to the conclusions and advice offered by textbooks that rely on social scientific studies. (MG)

Finds that communication-skills instruction generates (using the Binomial Effect Size Display) a 44% increase in critical-thinking ability. Finds that forensic participation demonstrated the largest positive impact on critical-thinking improvement, but that all communication skills experiences demonstrated significant improvement. (SR)
