Date of this Version Examined the effects of different
environmental measures on individual intellectual growth
patterns in 105 young children participating in a longitudinal
study. Intelligence (Stanford-Binet, 4th edition) was measured
at ages 3 through 6 yrs, and child's environment was assessed at
age 3 years using SES data and scores on the Home Observation
for Measurement of the Environment (HOME) Inventory. Growth
curve analyses revealed that HOME scores exerted a constant
influence on the expected composite, verbal, and nonverbal
intellectual skills at each age. Only SES influenced the rate of
growth, specifically nonverbal intellectual skills. The
magnitudes of these effects were moderate, but consistent,
regardless of whether age-standardized or subscale raw scores
were analyzed. These findings confirm that HOME and SES scores
are more than just different types of measures of the child's
environment.
