Stimulus suffixes and visual presentation

Abstract

Seven experiments studied whether irrelevant visual stimuli (stimulus suffixes) would interfere with immediate serial recall of supraspan lists of digits presented visually. Across experiments a wide number of conditions were run, varying in method of presentation (sequential or simultaneous), rate of list presentation, and presence or absence of articulatory suppression. In no condition did a visual suffix have a significant detrimental effect on recall. These results stand in marked contrast to those found when auditory lists and suffixes have been used. © 1987 Psychonomic Society, Inc.
