摘要

视觉注意力通常会转向即将发生的眼球回旋运动的目标。这一观察结果通常被解释为注意选择和眼球运动程序之间的强制性耦合。在这里,我们研究了这种耦合是否会因为对视觉目标和运动目标之间空间一致性的习惯性预期而得到促进。为此,我们进行了一项双任务(即同时进行的囊状移动任务和视觉辨别任务)实验,在实验中,男性和女性参与者都要接受训练,以预期囊状移动目标和注意探测刺激之间的空间一致性或不一致性。为了评估预期对运动前注意力分配的训练诱导效应,参与者随后完成了一个测试阶段,在该阶段中注意力探针的位置是随机的。结果表明,无论注意探针位置是否与囊状视线目标相匹配,辨别成绩都系统地偏向于预期的注意探针位置。总之,我们的研究结果表明,视觉注意力可以与正在进行的眼球运动程序大大脱钩,并表明习惯性预期在注意力-行动耦合中发挥着重要作用。

Training enables substantial decoupling of visual attention and saccade preparation

Visual attention is typically shifted toward the targets of upcoming saccadic eye movements. This observation is commonly interpreted in terms of an obligatory coupling between attentional selection and oculomotor programming. Here, we investigated whether this coupling is facilitated by a habitual expectation of spatial congruence between visual and motor targets. To this end, we conducted a dual-task (i.e., concurrent saccade task and visual discrimination task) experiment in which male and female participants were trained to either anticipate spatial congruence or incongruence between a saccade target and an attention probe stimulus. To assess training-induced effects of expectation on premotor attention allocation, participants subsequently completed a test phase in which the attention probe position was randomized. Results revealed that discrimination performance was systematically biased toward the expected attention probe position, irrespective of whether this position matched the saccade target or not. Overall, our findings demonstrate that visual attention can be substantially decoupled from ongoing oculomotor programming and suggest an important role of habitual expectations in the attention-action coupling.

期刊介绍: Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
