We contrasted visual search for targets presented in prototypical views and targets presented in nonprototypical views, when targets were defined by their names and when they were defined by the action that would normally be performed on them. The likelihood of the first fixation falling on the target was increased for prototypical-view targets falling in the lower visual field. When targets were defined by actions, the durations of fixations were reduced for targets in the lower field. The results are consistent with eye movements in search being affected by representations within the dorsal visual stream, where there is strong representation of the lower visual field. These representations are sensitive to the familiarity or the affordance offered by objects in prototypical views, and they are influenced by action-based templates for targets.
我们对比了在原型视图中呈现的目标与在非原型视图中呈现的目标的视觉搜索情况，目标分别由其名称定义以及由通常对其执行的动作定义。对于位于下视野的原型视图目标，首次注视落在目标上的可能性增加。当目标由动作定义时，下视野中目标的注视持续时间缩短。这些结果与搜索中的眼动受背侧视觉流内表征的影响一致，背侧视觉流中存在下视野的强烈表征。这些表征对原型视图中物体提供的熟悉度或可供性敏感，并且它们受目标的基于动作的模板影响。
