Infant Assessment Unit - Kagan Mobile Task

Title

Infant Assessment Unit - Kagan Mobile Task

Description

The Infant Assessment Unit (IAU) was part of the Longitudinal Cohort Study. The objective of the IAU was to observe how prenatal and postnatal conditions affect the health and cognitive functioning of infants during the first year of life. Consisting of several instruments, the IAU sought to measure infant cognition and quantify the experiences of the sampled infants from Cohort 0 during their first 12 months of life. Additionally, the IAU examined the circumstances surrounding the mother's pregnancy and the subsequent care received by the infant. The IAU was administered to subjects or primary caregivers in Cohort 0 only in Wave 1 of the LCS.

The Kagan Mobile Task/Latency to Grasp (PDF 1.7MG) was included in the IAU to summarize various behaviors, such as smiling and crying, as responses to novel visual stimuli. Measures of these behaviors, including latency to grasp, were used to describe the infant's overall temperamental disposition. It was administered to subjects.
