运用 Stroop 范式和情绪启动范式，探究冲突加工的信号作用，考察知觉加工早期认知冲突对后续加工的具体影响。采用2(启动条件：一致/冲突)×2(目标效价：积极/消极)的被试内设计。研究发现，情绪启动任务中，消极目标刺激在冲突启动条件下的反应时显著小于一致启动条件下的反应时，积极目标刺激在一致启动条件下的反应时显著小于冲突启动条件下的反应时，显示了显著的消极启动效应。结论：在知觉加工早期，认知冲突被视为一种消极信号，诱发消极启动效应，对后续加工产生影响。%To explore the signal function of conflict and investigate the impact how conflict plays on subsequent cognitive processing in early perceptual stage, the study used a combination of Stroop task and affective priming paradigm and adapted 2 (prime condition: non-conflict / conflict) ×2 (target valence: positive/ negative) within subject design when the stimulus onset asynchrony (SOA) is 200ms. In affective priming task, the RTs of negative targets after conflict primes were significant less than after non-conflict primes while the RTs of positive targets after non-conflict primes were significant less than conflict primes, showed significant negative priming effect. This study showed that cognitive conflict was viewed as a negative signal and induced negative priming effect in early perceptual processing, so it plays a negative influence on subsequent emotional processing.
