Effects of lateralized presentation on levels of processing in memory.
The present study utilized lateralized presentation of words in a level-of-processing paradigm. Eighty words were presented to subjects in four level-of-processing conditions: orthographic, phonetic, syntactic and semantic. Words were presented either to the left or right visual fields (Experiments 1 and 2), or centrally (Experiment 3). Both free recall and recognition retrieval conditions were utilized. There were no visual field differences in the recognition condition. In the free recall condition, there was an interaction between visual field of presentation and level of processing. Recall was greatest for phonetically and semantically processed words which had been presented to the right visual field. A left visual field advantage was found for syntactically processed words. Results are interpreted in the context of retrieval strategies and hemisphere-linked processing capacities.
