High and low spatial frequency information has been shown to contribute differently to the processing of emotional information. In three priming studies using spatial frequency filtered emotional face primes, emotional face targets, and an emotion categorization task, we investigated this issue further. Differences in the pattern of results between short and masked, and short and long unmasked presentation conditions emerged. Given long and unmasked prime presentation, high and low frequency primes triggered emotion-specific priming effects. Given brief and masked prime presentation in Experiment 2, we found a dissociation: High frequency primes caused a valence priming effect, whereas low frequency primes yielded a differentiation between low and high arousing information within the negative domain. Brief and unmasked prime presentation in Experiment 3 revealed that subliminal processing of primes was responsible for the pattern observed in Experiment 2. The implications of these findings for theories of early emotional information processing are discussed.
高空间频率信息和低空间频率信息在情感信息处理中发挥着不同的作用。在三项启动研究中，我们使用空间频率滤波后的情绪化面部启动刺激、情绪化面部目标刺激以及一项情感分类任务，对这一问题进行了进一步探究。短时间呈现与掩蔽呈现条件之间，以及短时间呈现与长时间非掩蔽呈现条件之间的结果模式存在差异。在长时间非掩蔽启动刺激呈现的情况下，高频和低频启动刺激会引发特定情感的启动效应。在实验2中，当启动刺激呈现时间较短且带有掩蔽时，我们发现了一种分离现象：高频启动刺激引发了效价启动效应，而低频启动刺激则在负性情绪范畴内，对低唤醒信息和高唤醒信息进行了区分。实验3中短时间非掩蔽启动刺激呈现的结果表明，启动刺激的阈下加工是实验2中观察到的模式的原因。我们还讨论了这些发现对早期情感信息加工理论的启示。
