Abstract
This study focused on the impact of stimulus presentation format in the gating paradigm with age. Two presentation formats were employed—the standard, successive format and a duration-blocked one, in which gates from word onset were blocked by duration (i.e., gates for the same word were not temporally adjacent). In Experiment 1, the effect of presentation format on adults’ recognition was assessed as a function of response format (written vs. oral). In Experiment 2, the effect of presentation format on kindergarteners’, first graders’, and adults’ recognition was assessed with an oral response format only. Performance was typically poorer for the successive format than for the duration-blocked one. The role of response perseveration and negative feedback in producing this effect is considered, as is the effect of word frequency and cohort size on recognition. Although the successive format yields a conservative picture of recognition, presentation format did not have a markedly different effect across the three age levels studied. Thus, the gating paradigm would seem to be an appropriate one for making developmental comparisons of spoken word recognition.
