An Examination of Message Elaboration as a Moderator of Psychological Reactance

The current study advances the literature on psychological reactance theory by examining the moderating role of message elaboration on the reactance process. Participants (N = 512) were randomly assigned to a message condition (freedom-threatening vs. non-freedom-threatening language) in a between-subjects quasi-experimental design. Message elaboration was not manipulated but rather varied naturally. Two topics were examined (energy conservation and organ donation). Results demonstrated that freedom-threatening language was positively associated with perceived freedom threat for both topics. No interaction effect of message elaboration and freedom-threatening language on perceived freedom threat was observed for either topic. Findings are discussed in terms of the theoretical and practical contributions of the current study.     

Strategic topic avoidance: an investigation of topic avoidance frequency,strategies used,and relational correlates

This research stresses the need to examine the relationship between topic avoidance and relational correlates (e.g., satisfaction and emotional closeness) from a message production theoretical perspective. Our approach—strategic topic avoidance—offers additional explanatory capabilities as the strategies with which interactants in close relationships avoid topics may be associated with perceptions of the relationship (after accounting for topic avoidance frequency). Moreover, relational correlates may also vary by the combination of overall topic avoidance frequency and certain topic avoidance strategies. The current research, therefore, assessed individuals' topic avoidance frequency levels and the frequency of using topic avoidance strategies in relation to satisfaction and closeness across three different relational types (i.e., significant others, mother–young‐adult, and father–young‐adult relationships). Results suggested that avoiding certain topics, such as current relational concerns, predicted levels of satisfaction and closeness across relationship types; however, cross‐relational differences also emerged. Strategies employed to avoid topics accounted for additional variance in satisfaction and closeness for relationships with significant others and mothers but not fathers. Analyses also demonstrated that overall topic avoidance frequency interacted with topic avoidance strategy use.     

The Composition and Sequencing of Communicative Acts to Solve Social Problems: Functionality and Inventiveness in Children's Interactions

A close examination of peer interactions of children between the ages of 5;0 and 7;0 reveal occurrences where children composed and sequenced their communicative acts in intricate ways that were functional as solutions to a suddenly emergent social dilemma. Their acts and act sequences functioned to place constraints on what followed in the interaction, such that they opposed the other's unwanted actions by making the other's cessation of the unwanted actions relevant, and interpretable in a socially positive way. These same acts and act sequences simultaneously steered the interaction away from conflict by not making a conflictful response relevant. Besides their dual functionality, these communicative acts were so tailored to the immediate context and situational dilemma that they have an inventive aspect. These data raise the theoretical question of what basis the children had for composing and sequencing communicative acts in situ that anticipate their interactional consequences and promote desired ones. A proposal is made in the concluding discussion that the basis for this capability is acquisition of “knowledge” of a set of Principles of Relevance in interactions and discourse.

Research productivity in communication: An analysis, 1996‐2001

The study provides an analysis of those scholars who produced a substantial number of articles in 24 communication journals during the period, 1996‐2001. The purpose of the study was to update the information provided in previous studies. Using data similar to that previously found in the Index to Journals in Communication Studies, the authors found that during the period a number of new names has appeared. As a result, the authors develop a list of the top one percent (50) of those researchers, as well as providing data on the institutions which these scholars represent. The minimum number of articles necessary during the period to be included was nine.
