PRIMARY outcome
Timeframe: One day (during testing)Population: Two participants were removed due to low accuracy (2 standard deviations below the mean) in one or more conditions.
Accuracy of responses to target item (% correct)- 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
