Semantic context effects in visual word recognition: An analysis of semantic strategies

Abstract

Using a procedure that isolates the facilitatory and interfering effects of a semantic context, the present study examines two distinct patterns of context effects. One pattern shows a dominance of facilitation for target words in a related context, and the other pattern shows a dominance of interference for target words in an unrelated context. The controlling factor seems to be the overall characteristics of the stimulus list. For materials that include semantic relationships that are consistent in the strength of the relationships, facilitation dominance obtains. For materials that include a wide range of semantic relationship strengths, interference dominance results. These two patterns of facilitation and interference are attributed to two semantic strategies available to subjects for using context information. The explication of the strategies includes a theoretical treatment of the present data. © 1980 Psychonomic Society, Inc.
