Visual streams and shifting attention

Neural correlates of causality judgment in physical and social context—The reversed effects of space and time

“…The activations of the occipital brain regions suggest increased perceptual processing mechanisms activated during the physical in contrast to social context. This interpretation is in line with studies showing that increased visual perceptual effort produces greater occipital lobe activation (Brown, 2009;Kravitz et al, 2011).…”

Enhanced dimension-specific visual working memory in grapheme–color synesthesia

“…One non-competing alternative explanation of our results is that grapheme–color synesthetes display broader, enhanced processing in the parvocellular visual pathway (Barnett et al, 2008; Rothen et al, 2012), which enables processing of color and high contrast stimuli (e.g., Brown, 2009). This hypothesis more readily explains synesthetes’ superior memory for achromatic visual stimuli that do not elicit color photisms (Rothen & Meier, 2010) than dual-coding and enhanced color processing accounts.…”

A biased activation theory of the cognitive and attentional modulation of emotion

“…It may provide the mechanism also for effects in for example the dorsal vs. the ventral visual system, in which attention to the motion of a moving object may enhance processing in the dorsal stream, and attention to the identity of the moving object may enhance processing in the ventral visual stream (Brown, 2009). Similar biased activation may contribute to the different localization in the prefrontal cortex of systems involved in “what” vs. “where” working memory (Deco et al, 2004; Rottschy et al, 2012).…”
