Approach-Avoidance Task examining approach bias to different foods
Description
This data originates from an approach-avoidance task examining approach bias towards food. Participants responded to the stimulus category (food or object) by pulling or pushing a joystick. Instructions were flipped from one block to the next.
Usage
data(foodAAT)
Format
An object of class "data.frame".
Details

is_pull: Whether the trial required an approach response (1) or an avoid response (0).
is_target: Whether the trial featured a food stimulus (1) or an object stimulus (0).
error: Whether the response was incorrect (1) or correct (0).
RT: The response initiation time.
FullRT: The time from stimulus onset to response completion.
trialnum: The trial number.
blocknum: The block number.
palatability: The participant's palatability rating for the stimulus (foods only).
