Abstract

The attentional pattern to emotional information in normal subjects (emotionally not disturbed subjects) was investigated. Particular attentional patterns to emotional information in normal population were found in several researches. But emotional effect in normal subjects was absent in most researches using emotional Stroop task. Many researchers (e.g., Mathews & MacLeod, 2002) supposed that the strong control of selective attention and task demand processing could easily intercept the input of irrelevant threat-related processing in the condition of direct competition between target-processing and irrelevant threat-related processing. In the present study, for leading a more strong input and processing of irrelevant emotion-related stimulus in normal participants, we primed the emotional stimulus before target stimulus in a modified Stroop task. Results have shown that in ISI of 90 ms, the priming of positive face slowed down color-naming latency and the priming of negative face accelerated it. Interestingly, this attentional pattern to negative information disappeared when emotional stimulus was presented for 60 ms and persist when emotional stimulus was presented for 30ms and masked immediately in same condition. In conclusion, normal subjects could automatically inhibit the emotional processing only when the perceptual code of negative stimulus was weak.
