Fig 1. Implicit Associations Task—Experimental stimuli.

A) Task blocks begin by identifying the classification condition. In this condition, participants must decide if the stimulus word is self-related or positively valenced (Me or Positive). The stimulus word is then displayed (B), which the participant then classifies (C). In this case the participant correctly chose that the stimulus word “fatigued” was not a “Me or Positive” word. Visual feedback of each choice is displayed under the yes or no button box (dashed lines), and feedback about the classification accuracy is displayed below the stimulus word, in this case with a green tick. D) In this example, the participant incorrectly chose that the stimulus word “healthy” was an other-related or negatively valenced word (You or Negative). Participants are reminded of which buttons of the 4 button response box they are holding indicate yes and no by the illustrations at the top left and right of each screen.
