The development and robustness of young children’s understanding of aspectuality

We investigated whether 6-year-olds’ understanding of perceptual aspectuality was sufficiently robust to deal with the presence of irrelevant information. A total of 32 children chose whether to look or feel to locate a specific object (identifiable by sight or touch) from four objects that were hidden. In half of the trials, the objects were different on only one modality (e.g., four objects that felt different but were the same color). In the remainder of the trials, the objects also differed (partially) on one irrelevant modality (e.g., four objects that felt different, two red and two blue, where the goal was to locate the soft object). Performance was worse on the latter trials. We discuss children’s difficulty in dealing with irrelevant information.
