Using the variant of the classical additional singleton paradigm, the influence of feature-based statistical regularities of singletons on the attentional suppression effect was investigated. The results showed that: (1) when participants were forced to adopt the feature search mode, the response times were significantly faster in all the conditions with singleton than in the condition without singleton; (2) compared with the condition with a low-probability color singleton, the response times were significantly faster in the trials of high-probability color singleton presented. The results show that the influence of statistical regularities on attention is not limited to the stimulus location, and the feature-based statistical regularities also affect the magnitude of the attentional suppression effect.

Key words: additional singleton paradigm, feature search strategy, statistical regularities, attentional suppression effect
