Effects of an early motor intervention on visual attention and object exploration in low-SES infants
Developmental differences in executive function (EF) between children of low- and high-socioeconomic status (SES) have been observed as early as six months of age. These deficits in low-SES infants may compound into the well-known achievement gap when children enter grade school. One way to address the developmental deficits seen in low-SES children is through early intervention that addresses components of EF. The current study implemented an intervention to address attention and object exploration deficits as a means to improve cognitive outcomes. The intervention, Play 4 Success, required all infants to practice sustained attention and also taught infants more sophisticated exploratory behaviors. Participants (n = 7 out of eventual 45), 6- to 10-month-old infants in Early Head Start, were placed into one of three intervention groups which taught a varying number of exploratory techniques: Social, Teach Two, or Teach Many. Infants’ visual attention and object exploration were tested before and after the two-week intervention. Preliminary results, collapsing data across all conditions, showed no significant change in total attention to people and a marginally significant decrease in total attention to toys. Time spent manually exploring objects was higher after the intervention and depth of exploration increased at a marginally significant level. These results provide preliminary support to the effectiveness of Play 4 Success, particularly the capability of the intervention to increase object exploration.
