Abstract
Ten [male] Wistar stock albino rats were trained to alternate in left-right choices, and then after a first choice, a delay was interposed before the next choice was permitted. Delays of zero (nominally), 5, 15, 30, 60, and 120 min. were used, and later, delays of 480 min. Percentage of alternations decreased from an average of 88.8 at zero delay (nominal zero) to 57.5 at 480 min. For all but the longest delay interval the proportion of alternations was significantly higher than chance (50%). These delays for rats are greater than any previously published findings[long dash]with one exception[long dash]and are said to bring findings for rats into line with findings with other spp.This publication has 4 references indexed in Scilit:
