Abstract: Towards the end of their first year, infants are initially learning to construct objects. Construction, or merging multiple objects into a single, unifying structure, requires combining cognitive and sensorimotor abilities. Since infants with a hand preference have greater manual proficiency than infants with no hand preference, infants with a hand preference are expected to be more skilled at construction. Since some evidence suggests that females may develop motor skills more quickly than males, sex may play a role in the development of construction; however no specific predictions are made. Fifty-three infants (26 females) were brought to the lab from the ages of 6-14 months across 9 monthly visits. Infants were given a handedness task across all visits to assess their handedness, and additionally given a construction task from 10-14 months to assess their constructing skill. Using multilevel Poisson longitudinal modeling, left-handed males constructed at a significantly slower rate across 10-14 months than all other groups. Left-handed males follow a unique trajectory of constructing skill, which could indicate differences in their spatial abilities and may also affect related cognitive abilities at later ages, such as hierarchical structuring or seriation.
