Insights
This study shows that behavioral interventions effectively improved eye contact in a child with pervasive developmental disorder-not otherwise specified (PDD-NOS). However, these improvements did not generalize to new communication partners.
Area of Science:
- Developmental Psychology
- Behavioral Therapy
- Autism Spectrum Disorders
Background:
- Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) often involves social communication deficits.
- Improving eye contact is crucial for social interaction in children with PDD-NOS.
Observation:
- A 4-year-old boy diagnosed with PDD-NOS participated in the study.
- Interventions were delivered during play-based therapy sessions with three therapists.
Findings:
- Differential reinforcement and most-to-least prompting significantly improved the child's eye contact.
- Improvements were maintained for at least three months post-intervention.
- Eye contact did not generalize to untrained communication partners.
Implications:
- Practitioners should consider generalization strategies for communication partners not directly involved in therapy.
- Further research is needed to explore methods for enhancing generalization of social skills in PDD-NOS.
Purpose:
Differential reinforcement and most-to-least prompting were implemented within the context of developmentally appropriate play activities in an effort to improve the eye contact between a 4-year-old boy with pervasive developmental disorder-not otherwise specified (PDD-NOS) and his three therapists.
Methods:
A multiple baseline design across therapists was used to examine the eye contact of a 4-year-old boy with PDD-NOS. Maintenance data were collected at 1, 2 and 3 months post intervention.
Results:
The intervention was effective and improvements in eye contact were maintained for at least 3 months post intervention. However, eye contact did not readily generalize across communication partners.
Conclusions:
Results suggest that eye contact may not generalize to communication partners who are not directly involved in intervention. Results are discussed in terms of implications for practitioners and directions for future research.
