Abstract: | In previous studies using a short-duration visual presentation (200-340 msec), presentation of a different colored suffix did not attenuate the visual suffix effect. In Experiment 1, color attenuated the suffix effect for a longer duration visual presentation (approximately 3-4 sec) during which the subject engaged in articulatory suppression to prevent auditory recoding. Experiments 2 and 3 confirmed that color does not attenuate the suffix effect for the short-duration presentations. In Experiment 4, recall of a long-duration presentation was not improved when the last digit was a different color, suggesting that the different color of the suffix improves recall by allowing the suffix to be excluded from visual short-term memory. The attenuation by color is consistent with the hypothesis that preattentive grouping governs the entry of information into visual short-term memory. |
