The Longitudinal Observation and Intervention Study: A Preliminary Report.
Caldwell, Bettye M.; And Others
This study investigated the decline in rate of development often observed in disadvantaged children, and compared the effectiveness of different types of intervention designed to prevent this decline. Approximately 125 infants from both middle and lower class backgrounds were recruited as subjects. Each infant was assigned to one of four experimental groups in which one of the following procedures was used: (1) testing of the infant with age-appropriate measures at 6, 12, 24, and 36 months of age; (2) testing of the infant every month from 8 through 12 months, and then quarterly from 12 to 36 months; (3) testing as in group 2 and experimental intervention by suggesting and demonstrating activities and toys which were given to the mother to help the baby "learn new things" in some developmental areas; or (4) testing as in groups 2 and 3 and home intervention in which the target was the parent-child unit who received biweekly tutoring sessions. The results contained in this preliminary report indicate that the predicted decline in developmental test scores did occur, and that neither of the intervention strategies were effective in circumventing it.
