简要总结
In this line of research, the researchers are examining the influence of relevance of a salient item on task performance, depending on overall task set.
详细描述
When finding a target item during visual search (looking for a pencil), a salient item can capture attention (your phone flashing from a message). Typical attention studies only examine salient items when shown as distractor during search, to ensure any attention to the items are driven by salience alone. However, the impact of salience may interact with the relevance of the item for the search task (e.g. how likely the salient item is to be the target). Here, the researchers investigate these interactions in a basic science study when participants perform an easy task or a difficult search task.

结局指标
主要结局
Button Press Reaction Time
时间窗: During Testing (single day)
Speed to respond correctly to the target- after participant finds the target shape on a computer screen, they press a button to indicate what shape they see
Button Press Accuracy
时间窗: During Testing (single day)
Accuracy of responses to target item- the researchers will measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button
