"This study varied the number of different responses and the similarity of the stimuli in relation to the responses in paired-associate lists…. It was found that similarity was a variable in learning and that the list with a single response for each group of similar adjectives showed high positive intralist transfer characteristics of concept learning. Retention did not seem related to similarity, but was uniformly high." 15 refs. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
