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 examine the visual information used for action and perception, skilled cricket batters anticipated the direction of balls bowled toward them using a coupled movement (an interceptive action that preserved the natural coupling between perception and action) or an uncoupled (verbal) response, in each of four different visual blur conditions (plano, +1.00, +2.00, +3.00). Coupled responses were found to be better than uncoupled ones, with the blurring of vision found to result in different effects for the coupled and uncoupled response conditions. Low levels of visual blur did not affect coupled anticipation, a finding consistent with the comparatively poorer visual information on which online interceptive actions are proposed to rely. In contrast, some evidence was found to suggest that low levels of blur may enhance the uncoupled verbal perception of movement.
耦合拦截动作被认为是神经处理和视觉信息的结果，这与用于非耦合感知反应的信息不同。为了研究用于动作和感知的视觉信息，熟练的板球击球手在四种不同的视觉模糊条件（平面、+1.00、+2.00、+3.00）下，分别使用耦合动作（一种保留了感知与动作之间自然耦合的拦截动作）或非耦合（言语）反应来预测向他们投来的球的方向。结果发现，耦合反应优于非耦合反应，并且发现视觉模糊对耦合和非耦合反应条件产生了不同的影响。低水平的视觉模糊并不影响耦合预测，这一发现与在线拦截动作所依赖的相对较差的视觉信息一致。相比之下，有证据表明低水平的模糊可能会增强对运动的非耦合言语感知。
