A substantial body of scholarship focused on the processes involved in message planning has accumulated in the communication literature. One of the central tenets of memory models upon which most of the message planning models are based is that dynamic memory systems organize and reorganize knowledge structures to maximize information processing efficiency. Accordingly, efficiency can be achieved by merely retrieving and enacting plans that have achieved goals previously under similar conditions. Plan failure, however, requires alteration or even production of an original plan. Although researchers have relied exclusively on output (e.g., response latency, memory tests) to draw inferences about planning processes, it is possible to observe cognitive processes more directly by measuring cortical responses. In the present study, electrical activity was monitored in the region of the dorsolateral prefrontal cortex during verbal planning. Results indicated that (a) electrical activity while planning under conditions that permitted enactment of verbal plans that required no modification was significantly lower than during planning in the initial trial but, (b) electrical activity while planning under conditions in which previous efforts failed was significantly higher than during planning in the initial trial. These results provide physical evidence for the hypothetical cognitive processes proposed in the cognitivist models of routine formation. [ABSTRACT FROM AUTHOR]

This study was undertaken to examine whether the relationships reported in the communication literature between Eysenck's BIG THREE personality dimensions and self-reported patterns of communication behavior remain robust when observation-based measures are used in place of self-reports. Target participants" responses to measures of these three personality dimensions were used to predict peer ratings of two patterns of communication behavior, verbal aggressiveness and affinity-seeking competence. Composite measures for variables were based on the results of confirmatory factor analysis, ensuring both internal and external consistency (parallelism). Results of a path analysis, in which targets" responses to personality measures were employed as exogenous variables and peer ratings of verbal aggressiveness and affinity-seeking competence were used as endogenous variables indicated that these data fit the model extremely well. Importantly, (1) substantial variation in peer rated affinity-seeking competence (R = .55) was attributed to the direct effects of extraversion and neuroticism (negative coefficient), and (2) substantial variation of peer rated verbal aggressiveness (R = .58) was attributable to direct effects of psychoticism and extraversion (negative coefficient) and an indirect effect of extraversion and neuroticism mediated by affinity-seeking competence (negative coefficient). Implications for communication theory and research are discussed. [ABSTRACT FROM AUTHOR]
