About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

normal or corrected to normal visual acuity, normal color vision

Exclusion criteria

Treatment and study plan

Relevance (Likelihood Salient Item is Target)

Behavioral

The proportion of trials, when the salient visual item is present in the array, where the salient item is the search target.

Primary outcomes

Button Press Reaction Time

Time frame: 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

Time frame: 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
