Visual-motor processing: relationships among age, dimensional variation, and the use of information redundancy

This study examined the hypothesis that age-related superiority in the ability to process complex stimuli was linked with age differences in the use of information redundancy. Seventy-two children (6-9 years of age) solved a series of puzzles that varied in complexity and redundancy. Significant correlations between age and completion times were found only for those puzzles that included some degree of information redundancy. Completion times on multidimensional puzzles that lacked redundancy were not significantly age related.
