On the Relation of Semantic Context Effects in Picture Naming and Semantic Categorization: Evidence from Aphasia

EasyChair Preprint 6649

Abstract

The continuous picture-naming paradigm requires naming of several members of different semantic categories (e.g., clothes: blouse, skirt, glove, hat, shoe) in a seemingly random order, separated by 2 to 8 unrelated objects. Naming latencies increase in a linear fashion with each additional category member. This effect is assumed to be located at the lexical level of language production (e.g., Howard et al., 2006; Oppenheim et al., 2010). A cumulative effect is also observed in a receptive semantic categorization task but here facilitation is observed (Belke, 2013). In our study, PWA with mild word-finding difficulties completed a continuous picture-naming task and a continuous semantic categorization task with identical materials. Reaction times were analyzed in addition to response accuracies. The participants showed cumulative semantic interference in the picture-naming task and cumulative  facilitation in the categorization task. Whether the individuals' interference effects can be predicted by their facilitation effects will be presented. This would point to a common conceptual-semantic origin of both effects (Belke, 2013). Theoretical and clinical implications will be discussed.

Keyphrases: aphasia, continuous picture naming, cumulative semantic facilitation, cumulative semantic interference, lexical access, semantic processing
