Recent literature confirms the effects of motor activities on the formation and reinforcement of movements in the first years of life among mentally retarded children. It is proposed that there is a relationship between formation of movements and improvements in motor-perceptual capabilities and academic achievement. These lead us to the idea that the phenomenon of perception, the role played b...

A new theoretical framework, executive-process interactive control (EPIC), is introduced for characterizing human performance of concurrent perceptual-motor and cognitive tasks. On the basis of EPIC, computational models may be formulated to simulate multiple-task performance under a variety of circumstances. These models account well for reaction-time data from representative situations such a...

We investigated a visual-perceptual and haptic-perceptual training program to enhance motor skills and Chinese handwriting performance among children with handwriting difficulties. The participants were 28 first- and second-grade children with handwriting difficulties. They were matched according to age and then randomly assigned into a control group or an experimental group. Participants in th...

Performance modeling has been made easier by architectures which package psychological theory for reuse at useful levels of abstraction. CPM-GOMS uses templates of behavior to package at a task level (e.g., mouse move-click, typing) predictions of lower-level cognitive, perceptual, and motor resource use. CPM-GOMS also has a theory for interleaving resource use between templates. One example of...
