Abstract
The effect of category membership on the processing of both words and pictures was investigated,
'vith special regard to the category interference effect discussed in Kroll and Smith (1989).
Response latencies for both decision and naming tasks were evaluated using words-only, picturesonly,
and mixed words-and-pictures lists. Comparisons were made between a lists of items from
the same conceptual category and a list which was non-categorical. Picture decision, word
naming, and object naming- the tasks which, theoretically, require access to the conceptual
store- all showed faster RTs for categorical lists than non-categorical ones. The results of these
unmixed conditions support a model of spreading activation providing a category facilitation effect.
However, results from mixed conditions (words-and-pictures-together -naming or -decision) were
inconclusive, possibly suggesting a category interference effect.
