注意一种刺激而忽略另一种刺激对视觉和惯性（前庭、躯体感觉、本体感觉）刺激整合的影响程度目前尚不清楚。目前还不清楚线索整合是如何影响的线索冲突的意识。我们研究了这些问题，使用一个回合再现范式，参与者坐在一个运动平台上配备了投影屏幕，并被要求积极返回一个组合的视觉和惯性全身旋转围绕地球垂直轴。通过在主动返回过程中引入线索冲突，并询问参与者是否注意到线索冲突，我们测量了每个线索对反应的影响。我们发现，任务指令有一个显着的影响线索权重的反应，更高的权重分配给出席的方式，只有当参与者注意到线索冲突。这表明，参与者使用任务诱导的注意，以减少与任务指令冲突的刺激的影响。
The extent to which attending to one stimulus while ignoring another influences the integration of visual and inertial (vestibular, somatosensory, proprioceptive) stimuli is currently unknown. It is also unclear how cue integration is affected by an awareness of cue conflicts. We investigated these questions using a turn-reproduction paradigm, where participants were seated on a motion platform equipped with a projection screen and were asked to actively return a combined visual and inertial whole-body rotation around an earth-vertical axis. By introducing cue conflicts during the active return and asking the participants whether they had noticed a cue conflict, we measured the influence of each cue on the response. We found that the task instruction had a significant effect on cue weighting in the response, with a higher weight assigned to the attended modality, only when participants noticed the cue conflict. This suggests that participants used task-induced attention to reduce the influence of stimuli that conflict with the task instructions.
