This paper attempted to examine systematically, analytically, and synthetically cognitive style in general, and field dependence vs. field independence in specific. It includes two parts. The first part examined its conceptual definition, its operational definition, its characteristics, and its categories and dimensions. The second part examined four theories of cognitive style--- Witkin’s differentiation theory; Wardell & Royce’s multi-factor theory; Guilford’s intellectual executive function theory; and Davis & Cochran’s information processing theory. They were discussed, criticized, and synthesized. It can be predicted that this cognitive style as a new construct in psychology affects student learning, teacher teaching, and techer-student interaction. |
