Manipulated retrievability in free recall.

Acquisition and familiarization hypotheses in paired-associate learning.

“…It would appear that neither the results of Exp. I nor those of Young and Barton (1972) can be accounted for by a familiarization explanation. Indeed, to the extent that the VD pairs of the experimental sublist in Exp.…”

“…A recent series of studies attempted to investigate the acquisition of such variables as meauingfulness (M) and imagery (I) in the laboratory. In general, the paradigm employed was one in which a pairedassociate (PA) list was first learned followed by the learning of the PA responses in a free-recall list (Young & Barton, 1972). The M, I, and organization of the stimuli were varied during PA learning in various experiments.…”

“…The design can be summarized as a 2X2X2XS mixed factorial (» = 15 per cell). The verbal materials were taken from the same sources as were those in Young and Barton (1972). The nouns had A or AA Thorndike-Lorge ratings, and the CVC lists had median association values of 20 with a range of 17 to 25.…”
