This article first presents a conception of word recognition involving both phonological and orthographic processes. Three different explanations about the origin of orthographic processes in word recognition are then discussed. These explanations are: (1) differences in orthographic memory, (2) differences in phonological processes and (3) differences in leisure time reading. In accord with the third explanation, it is argued that automatic orthographic word recognition is directly dependent on children's amount of reading practice in an out‐of‐school setting. Educational implications of this emphasis on leisure time reading effects are also discussed.
