A classical definition of automaticity establishes that automatic processing occurs without attention or consciousness, and cannot be controlled. Previous studies have demonstrated that semantic priming can be reduced if attention is directed to a low-level of analysis. This finding suggests that semantic processing is not automatic since it can be controlled. In this paper, we present two experiments that demonstrate that semantic processing may occur in the absence of attention and consciousness. A negative semantic priming effect was found when a (...) low-level prime-task was required and when a masked lexical decision prime-task was performed . This paper also discusses the limitations of the inhibitory mechanism involved in negative semantic priming effect. (shrink)

The Influence of Emotional and Non-emotional Concepts Activation on Information Processing and Unintentional Memorizing The aim of the work is to compare mechanisms of semantic and emotional processing and memory. Targets were primed by category name. The congruency of prime and target was manipulated. The reaction time of lexical decisions and the effects of unintentional memorizing of word targets were measured. Activation of semantic and emotional nodes leads to faster processing of related concepts: congruent targets are processed faster than incongruent. (...) Processing congruent primed emotional concepts depends on their modality: anger and joy words are processed faster than sadness. Thus, congruently primed activating emotional concepts are processed differently from congruently primed deactivating concepts. The effectiveness of unintentional memory of emotional and non-emotional concepts is based on different mechanisms: congruently primed emotional words are better remembered than incongruently primed. The results are discussed in the framework of spreading activation theory and theory of emotional memory. (shrink)
