Valence-specific modulation in the accumulation of perceptual evidence prior to visual scene recognition.

Visual scene recognition is a dynamic process through which incoming sensory information is iteratively compared with predictions regarding the most likely identity of the input stimulus. In this study, we used a novel progressive unfolding task to characterize the accumulation of perceptual evidenc...
