The present study explored the temporal allocation of attention in groups of 8-year-old children, 10-year-old children, and adults performing a rapid serial visual presentation task. In a dual-condition task, participants had to detect a briefly presented target (T2) after identifying an initial target (T1) embedded in a random series of…

The developmental change from global toward dimensional classifications, usually observed in vision, was investigated in haptics with stimuli varying according to their size and roughness. Results indicated that, although more overall similarity classifications were observed in children than in adults, this kind of classification was never…

Two experiments studied the impact of the nature of information available at different processing levels on differences in haptic (tactile) and in visual, free classification development. Found that exploration characteristics (involving simultaneous versus independent processing of stimulus dimensions) and presentation of the stimulus dimensions…
