Abstract
Gradation of a response is a form of amplification control which determines that the response as a whole is appropriately graded in effort. The present study is an investigation of the effects of changes in resistance to cranking, amplitude of movement, and direction of movement on the gradation of the response in hand cranking. Criteria of gradation were derived from strain gauge and EMG records. A modification in gradation occurred principally when the resistance to movement changed appreciably. The findings are discussed in terms of one basic pattern of organization that is used, despite variations in task conditions.Keywords
