Ego Depletion Manipulations|
Using similar procedures as Gilbert et al. (1988), the attention control manipulation involves participants watching a 6-minute video clip (without audio) of a woman being interviewed by an off-camera interviewer. Participants are instructed that that they will later be making person-perception judgments of the interviewee because the experiment concerns nonverbal assessments of personality. In addition to the woman being interviewed, the tape shows a series of common one-syllable words (e.g., play) at the bottom of the screen for 10 s each. The words are printed in black, framed by a white background, and were confined to the bottom quarter of the screen. Thus, the words are readily apparent but did not dominate the main action on the screen. These words have no relationship to the woman being interviewed. Half of the participants are given no instructions regarding the irrelevant words, nor were they made aware of the words prior to viewing the video, whereas the other participants are instructed “not to read or look at any words that may appear on the screen.” Moreover, participants in the attention control condition are told to redirect their gaze to the woman being interviewed if they found themselves looking at the words.
