| Abstract: | Children from populations lacking verbal proficiency were given an interference list of paired associates (high within-list stimulus similarity) or 1 of 2 noninterference lists (low stimulus similarity), under a standard control condition (pictorial items side by side) or an imagery condition (items depicted as interacting). In Experiment I, with deaf children 6–10 years old, the imagery condition facilitated performance on the interference list, mainly by reducing generalization errors. There was significant interference only in the control condition. Unexpectedly, imagery failed to improve performance on the noninterference lists. In Experiment II, with hearing children 4–5 years old, there was significant interference in both the imagery and the control condition. Imagery significantly facilitated performance in all lists, but did not reduce interference, apparently because it did not reduce generalization errors. Thus, imagery (a) facilitates performance by increasing the memorability of stimulus-response associations, and (b) reduces interference by reducing confusion among similar stimuli. |
