Data Analysis Plan The raw data were analyzed as the mean BOLD activations and their standard deviations (Figure 5). Data were analyzed in 2 (Age) X 4 (Stimuli), within-subjects analysis of variance (ANOVA). Data regarding the face and scrambled face conditions were analyzed using a 2 (age) X 2 (Face Stimuli and Scrambled Face Stimuli), within-subjects ANOVA. Data regarding only the multi-part and chain objects stimuli were then analyzed using a 2 (Age) X 2 (Multi-Part Object, Chain Object), within subjects ANOVA. Lastly, the relationship between the BOLD response to familiar objects in 4-month-olds and the BOLD response to faces at 4-month-olds were analyzed using a t-test.
Descriptive Statistics There was very little difference between participants in regard to gender (Males, n = 7, Females, n = 9) and race (White, n = 16). All of the infants were approximately 1-month-old at the first session (M = 1.1) and 4-months-old (M = 3.9) at the second session.
Raw Data When examining the raw data, the average change in the BOLD signal for faces was significant (1.8% change) whereas the BOLD signal for the other stimuli was not significant (scrambled faces .35% change, familiar objects .37% change, novel objects .35% change) when the infants were 1-month-old. When the infants were 4-months-old and measured a second time, the average change was significant for face and familiar stimuli (1.75% and 1.25%). When measured the second time, the change in BOLD signal remained…
