Outcome Measures

Primary Outcomes (4)

  • Button Press Reaction Time

    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

    During Testing (single day)

  • Button Press Accuracy

    Accuracy of responses to target item- we will measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button

    During Testing (single day)

  • Proactive EEG Activity

    Proactive (pre-search) Measures of EEG Theta Activity

    During Testing (single day)

  • Reactive EEG Activity

    Reactive (post-search) Measures of EEG Alpha Activity

    During Testing (single day)
