20. ABSTRACT (Centinue en revere. aide It neceea7 eand Identify br block numbar)

Current attentionai research and theory are related to the developmentof skilled performance. Imbadis is given to how performance changes withpractice. Dual process attention theory is reviewed examining the distinctionbetween automatic and controlled processing. The changing interactionsbetween automatic and controlled processing in the development of Aill arediscussed. It Is proposed that consistent practice'produces automatic-productions which perform consistent transformations in a heterarchial

20 Abstract

_system. Automatic productions are proposed to: be modular; shov hLghtransfer; become resource free; not be under direct control; and be fast,

accurate, and coordinated. Controlled processing is assumed to develop

automatic processing, maintain strategy and time varying information, and

perform problem selving activities. Perceptual data, some motor data, and

several motor performance examples are presented to illustrate automatic/

controlled processing effects. The relationship to current theories of

motor skill are discussed, New research paradigms suggested by the current

approach are discussed.
