![]() ![]() ![]() The purpose of the present research was to examine the influence of cognitive processes on discourse coherence ability measured across different discourse elicitation tasks collected from younger and older cognitively healthy adults.ĭiscourse schemas serve as organizing frameworks for placing the essential discourse elements within a language sample ( Bloom, Borod, Santschi-Haywoor, Pick, & Obler, 1996 Peterson & McCabe, 1983). Further, cognitive functions that may contribute to maintenance of global coherence have not been readily specified in the literature and empirical evidence is lacking. However, these factors have not been investigated collectively to determine their influence on discourse coherence ability. ![]() Factors such as discourse schema, cognitive demands, and age may contribute to how well discourse is perceived as coherent. For the older group, cognitive measures were related to global coherence of stories and procedures.ĭiscourse coherence can be conceptualized as representing the listener’s ability to interpret the overall meaning conveyed by the speaker. For the younger group, there were no observed significant relationships. The influence of cognitive processes on maintenance of global coherence differed for the two age groups. Across discourse elicitation tasks the lowest global coherence scores were found for recounts compared to the other discourse elicitation tasks. Group differences on the global coherence scale were found for only one type of discourse – recounts. Participants also completed memory and attention measures. Study participants produced oral language samples in response to five commonly used discourse elicitation tasks and they were analyzed for maintenance of global coherence. The purpose of the present research was to examine the influence of cognitive processes on discourse global coherence ability measured across different discourse tasks and collected from younger (n = 40 20–39 y.o.) and older (n = 40 70–87 y.o.) cognitively healthy adults. ![]()
