| It is well known that language processing is primarily a function of the left hemisphere, however, there are some language functions that are bilaterally organized. Lupker & Sanders (1982) conducted two experiments using a picture-word interference task to assess the hemispheric differences in semantic processing. Results of these and other similar studies have obtained conflicting results. The present study is a conceptual replication of Lupker & Sanders (1982). A finger-tapping method was used to assess the hemispheric differences in four conditions: tapping alone, picture alone, semantically related word, and semantically unrelated word. Results show that the semantically related condition interferes with right hand finger tapping to a greater degree than with left hand finger tapping, indicating greater left hemisphere involvement in this condition. |
