Negative priming without reaction time: Effects on identification of masked letters

Abstract

Responses to an object are often slower and/or less accurate if that object is related to a recently ignored object. This negative priming effect has previously been examined only in reaction time tasks. In the present experiment, target letters and flanking distractor letters were displayed for 33, 100, or 300 msec, followed by a pattern mask. Subjects attempted to identify the target letters, with no demand for speed. Identification accuracy was reduced for targets that matched distractors presented on the immediately preceding trial. However, there was no bias against reporting preceding distractors on catch trials with no presented target. Implications for theories of negative priming are discussed. © 1995 Psychonomic Society, Inc.
