Abstract

AbstractMeasures of attention and memory were evaluated in 6‐ to 9‐month‐old infants from two diverse contexts. One sample consisted of African infants residing in rural Malawi (N = 228, 118 girls, 110 boys). The other sample consisted of racially diverse infants residing in suburban California (N = 48, 24 girls, 24 boys). Infants were tested in an eye‐tracking version of the visual paired comparison procedure and were shown racially familiar faces. The eye tracking data were parsed into individual looks, revealing that both groups of infants showed significant memory performance. However, how a look was operationally defined impacted some—but not other—measures of infant VPC performance.Research Highlights In both the US and Malawi, 6‐ to 9‐month‐old infants showed evidence of memory for faces they had previously viewed during a familiarization period. Infant age was associated with peak look duration and memory performance in both contexts. Different operational definitions of a look yielded consistent findings for peak look duration and novelty preference scores—but not shift rate. Operationalization of look‐defined measures is an important consideration for studies of infants in different cultural contexts.
