| In the previous study we examined age factors in effects of exposure to color and color-word cues upon later color discrimination task. As a result, the old participants were less affected by the cues, whereas the young participants’ response seemed to be inhibited by color cue information. For further investigation, we conducted a color-word discrimination experiment under the equivalent setting. The target was color-word of “red” or “green” (in Japanese), preceded by a cue with 4 kinds of color, color-word, congruent colored word, and conflict colored word. Young and old participants were instructed to discriminate the target with ignoring the cue. Not surprisingly the old participants generally responded slower than the young. There was, however, an asymmetrical change in effect of the cues from that found in the color discrimination experiment between the participant groups. Namely, the old participants’ response was inhibited by the no word cue in the present study, whereas the young participants showed less effect of the cues. This result could not be merely attributed to differences in the rate of processing and/or responsiveness to relevant cue information. Instead it suggests that a qualitative difference in interaction of word and color processing arises in aging. |
