Routine human behavior has often been attributed to plans-mental representations of sequences goals and actions-but can also be attributed to more opportunistic interactions of mind and a structured environment. This study asks whether performance on a task traditionally analyzed in terms of plans can be better understood from a "situated" (or "embodied") perspective. A saccade-contingent display-updating paradigm is used to change the environment by adding, deleting, and moving task-relevant objects without participants' direct awareness. Response latencies, action patterns, and eye movements all indicate that performance is guided not by plans stored in memory but by a control routine bound to objects as needed by perception and selective attention. The results have implications for interpreting everyday task performance and particular neuropsychological deficits.
日常行为通常归因于计划——心理对序列、目标和动作的表示——但也可以归因于思维和结构化环境的更具机会性的相互作用。本研究询问在传统上根据计划进行分析的任务中，是否可以从“情境”（或“体现”）的角度更好地理解表现。使用眼跳 contingent 显示更新范式来改变环境，在参与者没有直接意识的情况下添加、删除和移动与任务相关的对象。响应潜伏期、动作模式和眼动都表明，表现不是由存储在记忆中的计划指导的，而是由根据感知和选择性注意的需要绑定到对象的控制例程指导的。结果对解释日常任务表现和特定神经心理缺陷具有启示意义。
