Our study compared means‐end exploration in infants at risk (AR) for autism and typically developing (TD) infants using a nested box paradigm. Sixteen AR and 16 TD infants were observed at 9, 12, and 15 months with follow‐up at 18 and 24 months. We collected video data on three tasks involving retrieval of a small toy by opening (a) an opaque box, (b) a transparent box, and (c) two nested boxes. Dependent variables included hand bias, time to completion, bilateral hand use, problem‐solving strategies used, and tester assistance required. There were no group differences in terms of hand biases. Compared to TD infants, AR infants had lower bilateral hand use, poor problem solving skills, and required greater assistance. Both groups demonstrated age‐related improvements in motor and cognitive skills. Means‐end exploration provides a window into the bilateral coordination and motor planning/problem‐solving abilities of young infants at risk for autism. Lastly, object retrieval tasks could serve as important learning contexts for at‐risk infants.
