Seven experiments were designed to examine the role of attention in the development of mental codes regarding pattern-masked word inputs presented at various identification thresholds. Depending upon type of report required about pattern-masked prime words, either a positive repetition or an associative facilitation effect has been obtained in a lexical decision task. Most notably, associative inhibition effects were also obtained when either a prime or a probe word was slightly moved from its original position. The pattern of results indicates that visual and semantic codes are developed by focused attention to pattern-masked prime words and that these mental codes are locationally specific. Comparison of our results with Carr and Dagenbach's (1990) suggests that associative inhibition effects in our study are qualita-tively different from the effects they have found.
