Outcome Measures

Primary Outcomes (1)

  • Participants' Average Time Spent Looking at Stimuli According to Condition

    Infants' looking time to affiliation vs. disengagement stimuli was measured by two coders blind to the condition that infants were assigned to. Then, the values from each coders were compared and if there was disagreement, after discussion one value was selected. Thus, the reported outcome is the single value that both coders produced or agreed upon values from the two coders.

    After the infants completed the study (which lasted about 10 minutes), two coders viewed the video recording of the session to measure infants' looking at the affiliation and disengagement stimuli.

Study Arms (3)

White-White

EXPERIMENTAL

Infants will first view 4 familiarization trials, in which the two adults each take turns waving and saying a short sentence. Each trial will last 10.5s. Which adult speaks first and which side she appears on will be counterbalanced. These familiarization trials will ensure infants encode each person separately. Then infants will watch 6 test trials (3 affiliation and 3 disengagement). The test trials will alternate, and the order will be counterbalanced across infants. In affiliation trials, the two adults will say "hello" and wave, whereas in the disengagement trials, the two adults will say "hmph", and turn away from each other. Both affiliation and disengagement will have the same length (3s), with actors maintaining the same distance from each other throughout the video. The procedure will be identical for all arms except in "White-White" arm, the two adults infants see will be two White adults.

Other: Basic Science

Black-Black

EXPERIMENTAL

The procedure is identical to the "White-White" arm except the two adults infants see will be two Black adults.

Other: Basic Science

Black-White

EXPERIMENTAL

The procedure is identical to the "White-White" arm except the two adults infants see will be one White and one Black adult.

Other: Basic Science

Interventions

This is a basic science experiment to test whether infants' looking time to video stimuli differ according to the race of the individuals shown.
