Voluntary motor actions aim at and are thus governed by predictable action effects. Therefore, representations of an action's effects normally must become activated prior to the action itself. In 5 psychological refractory period experiments the authors investigated whether the activation of such effect representations coincides with the response…

Imaginal perspective switches are often considered to be difficult, because they call for additional cognitive transformations of object coordinates (transformation hypothesis). Recent research suggests that problems can also result from conflicts between incompatible sensorimotor and cognitive object location codes during response specification…

It is argued that the current theoretical orientation of motor behavior research toward information processing is only at the descriptive level. An outline of requirements for motor behaviorists to discover the mental operations that precede motor performance is presented. It is suggested that unless basic knowledge is obtained on how movement…

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)

This study examining children's ability to organize information for the purpose of recall was designed to control for verbal ability differences. The participants were 10 boys and 10 girls each from kindergarten, 2nd, 4th and 6th grades. A modified "Simon Says" game was used to enable the children to respond to eight selected verbal and motor…

The project described here focused on obtaining basic information on the memory representation of movement stimuli. When a learner makes a simple movement and is later asked to reproduce it, what is abstracted from the first movement that allows accurate reproduction of the second. The underlying assumption of the project was that unless basic…
