The authors reported on assessment of three young infants, ages 4, 7, and 9 months, who were assessed for affect, social interest, eye contact avoidance, and response to name. The authors investigated the feasibility of implementing an intervention to target social behaviors. Results demonstrated that consistently low or erratic levels of social behavior were evident throughout the baseline assessment period; these patterns could be improved with a brief intervention (a modified Pivotal Response Treatment) showing an immediate increase and stability of social engagement, and social engagement remained at a stable and high level at follow-up. The authors discussed the results terms of implications of early assessment and intervention for clinical populations, including infants with autism spectrum disorder.
