Memory connections between thematically similar episodes.

Investigated the use of cross-episode connections (i.e., when 2 episodes with a shared theme are connected through a thematic structure) in comprehension and memory in 6 experiments with 106 undergraduates. Results from the use of a priming technique in Exps I and II indicate that verification time for a test sentence from 1 story was speeded by an immediately preceding test sentence from a thematically similar story but only when Ss were given instructions to rate the similarities of the stories. In Exp III–VI, a single test sentence was presented immediately after a story was read, with timing controlled by presenting the story one word at a time. Response time for a test sentence from a previously read story was facilitated if the immediately preceding story was thematically similar but only if the previously read story was extensively prestudied. It is concluded that during reading of an episode, thematic information may be encoded to lead to activation of similar episodes and formation of connections in memory between episodes, but such encoding is not automatic and depends on Ss' strategies and task difficulty. Sample stories are appended. (36 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
