This paper examines the conceptual similarities between the psychological concept of attitude and that of intrinsic motivation in sport and physical education research. These concepts share similar conceptual frameworks and components, and are considered to affect learners` achievement in physical education and active participation in sport or physical activity. Similar affective and cognitive components underlie these concepts. The shared components in these concepts are influenced similarly by personal and situation factors. It is suggested that an integrative perspective based on diverse but similar psychological concepts in sport and physical education research be implemented to discover conceptual foundations of human performance and to see what encourages spontaneous, active and consistent participation in sport and physical education.
