Abstract (summary)

The activation of words in semantic memory occurs through automatic or controlled processes. Semantic priming experiments have revealed that these processes may be influenced by word relatedness and word expectancy. In a primed lexical decision task, automatic and controlled processing in ten mild to moderate individuals with aphasia were investigated through manipulation of stimulus relatedness, stimulus expectancy and stimulus onset asynchrony (SOA). The group with aphasia was significantly influenced by expectancy at the short and long SOA. The overall results of this study suggest that lexical-semantic activation in individuals with mild to moderate aphasia is influenced by strategic processing.
