Abstract
The current study utilized a priming paradigm in conjunction with a visual halffield presentation to determine if the right hemisphere contributes to pragmatic processing. Primes included conversational dialogues that either performed a speech act or did not. The targets identified the speech act and were presented to one of the two visual fields (lvf-RH or rvf-LH). It was hypothesized that the right visual field-left hemisphere (rvf-LH) would be more accurate and faster at identifying targets regardless of the script type that preceded it and the left visual field-right hemisphere (lvf-RH) would be significantly more accurate and faster at identifying targets when preceded by a script that performed the identified speech act. Results indicated that the lvf-RH was more accurate and faster at identifying a target regardless of the type of script that preceded it, while the rvf-LH was differentially affected by the type of script.
