The study examines the effects of the qualitative factors size and complexity of stimulus objects on preschool and first grade children on a learning task. Choice behavior is looked at with regards to initial choice (with the eyes) and final choice (with the hands). Other variables included in the analysis are long-term novelty and proportion of looks towards the rewarded object as a function of positive (choosing the rewarded object) and negative (choosing the unrewarded) choice outcomes. The results showed that first grade children are better at utilizing stimulus characteristics to aid their choice behavior, and further, that the specific levels of the characteristics studied that are attended to are high complexity and large size, as well as high long-term novelty.
