Distinctiveness effect due to contextual information in a categorization task
The main objective of our study was to confirm that the distinctiveness effect could emerge in implicit memory tasks and to show that the specificity of an item can be varied by manipulating the contextual information associated with the item during encoding. In an encoding phase and test phase, par...

In an encoding phase and test phase, participants had to categorize target words as referring to artifactual or natural items. Each target word was associated with a context consisting of a colored frame in which the word was presented. To manipulate the distinctiveness of the contextual information, 75 % of the words were encoded with the same color (frequent context) and the remaining 25 % with a different color (rare context). We tested the context effect by presenting words in the test phase with a context of either the same color as in the encoding phase or the other color. The results confirmed our predictions and are discussed in the theoretical framework of episodic memory models. L’objectif principal de notre étude était de confirmer que l’effet de distinctivité peut se manifester dans les tâches de mémoire implicite et de montrer que la spécificité d'un élément peut être modifié par la manipulation de l'information contextuelle associée à un élément lors de l'encodage. Au cours d'une phase d'encodage et une phase de test, les participants avaient à catégoriser les mots cibles comme se référant à des éléments naturels ou des artefacts. Chaque mot cible était associée à un contexte qui se composait d'un cadre coloré dans lequel un mot a été présenté. Pour manipuler le caractère distinctif de l'information contextuelle, les trois quarts des mots ont été codées avec la même couleur (contexte fréquent), tandis que l'autre quart a été encodé avec une autre couleur (contexte rare). L'effet de contexte a été testé en présentant des mots dans la phase test avec la même couleur de la phase d’encodage ou avec la couleur inverse. Les résultats ont confirmé nos prédictions et sont discutés dans le cadre théorique des modèles de la mémoire purement épisodique. |
