Recognition latency for pictures and words as a function of encoded-feature similarity.
In separate trials of a same-different recognition task, a single target item presented as either a picture or a word was followed after a 30-sec delay by a single test item, either a picture or a word. Test items were either nominal matches for the target (same) or one of five related distractor items. Distractors were selected to resemble the target item on one of five dimensions: orthographic, acoustic, conceptual (functional or categorical), schematic (similar in shape), or neutral. Same-different reaction times were found to vary systematically as a function of depiction mode of target and/or test items and by distractor type. Verbally related distractors (orthographic and acoustic) produced longer reaction times when target or test items or both were presented as printed words. When target or test items were presented as pictures, schematic and conceptual distractors produced the longest rejection latencies.
