==Convergent semantic processing==

Convergent semantic processing occurs during tasks that elicit a limited number of responses. During these tasks, subjects must suppress alternate options in order to select a single best option from a multitude of choices. It is believed that the left hemisphere of the brain dominates convergent semantic processing due to the fine grained, small window of temporal integration.<ref>{{Cite journal |last1=Faust |first1=Miriam |last2=Lavidor |first2=Michal |date=2003-10-01 |title=Semantically convergent and semantically divergent priming in the cerebral hemispheres: lexical decision and semantic judgment |url=https://www.sciencedirect.com/science/article/pii/S0926641003001721 |journal=Cognitive Brain Research |volume=17 |issue=3 |pages=585–597 |doi=10.1016/S0926-6410(03)00172-1 |issn=0926-6410 |pmid=14561447|url-access=subscription }}</ref><ref>{{Cite web| title=Choosing words: left hemisphere, right hemisphere, or both?
