Abstract	Coupled interceptive actions are understood to be the result of neural processing - and visual information - which is distinct from that used for uncoupled perceptual responses. To date, the majority of studies examining skilled interception have relied on uncoupled perceptual responses; as a result it has been suggested that our current knowledge of the neural processes underpinning skilled interception is somewhat limited and biased (van der Kamp, Rivas, van Doorn, & Savelsbergh, 2008). Based on the distribution of the human visual pathways, it is understood that perceptual-cognitive responses produced by the ventral pathway rely on visual information of better quality than the relatively blurred information used for online interceptive responses produced by the dorsal pathway. As a result it was hypothesised that low levels of visual blur would adversely affect a coupled response, but not an uncoupled one. To examine the visual information used for action and perception, skilled cricket batters anticipated the direction of balls bowled towards them using a coupled hitting movement and an uncoupled verbal response in each of four different visual blur conditions (plano, 1.00, 2.00, 3.00). When anticipating outcomes with habitual (unblurred) vision, coupled responses were found to be more accurate than uncoupled ones (p < .01), highlighting the importance of the relationship between perception and action when seeking to examine perceptual-motor skills. ANOVA testing revealed a significant interaction between coupling and blur (F(3,18) = 3.70, p < .05). Low levels of visual blur did not affect coupled anticipation, a finding consistent with the relatively poorer visual information which online interceptive actions are proposed to rely on. In contrast, evidence was found to suggest that low levels of blur may enhance the uncoupled (verbal) perception of movement. This rather counterintuitive finding is considered in light of other psychological studies which have reported enhanced movement perception with the introduction of visual blur.
