L'effet de l'hétérogénéité sémantique dans la détection de mots

The effects of three semantic factors (semantic priming of the target, semantic distance between the word-target and distractors, and semantic heterogeneity of the target context) on the detection of a word among other words were examined by using the classical paradigm of target detection (varying the number of distractors). Results showed that these three semantic factors affect performance: a target was better detected 1) when primed by its superordinate category than when it was defined as the “odd-one-out”; 2) when the semantic context was homogeneous than heterogeneous; and 3) when it was semantically unrelated to the context than semantically related. These results help specifying the cognitive processing of each word while searching for a word among others.
