Unformatted text preview: namic semantic fields:  better selection in LH; relatively coarser coding in RH Right Hemisphere RULER foot TOES foot CUT Small but strongly activated; Focused on dominant or contextually relevant concepts - easy to select, interpret, output Large but weakly activated; Diffuse, including secondary and less relevant concepts - hard to select, output Activity / power Left Hemisphere small semantic fields larger semantic fields - categorical interpretation - weak, graded interpretation Semantic space semantic space Categorical versus graded activation foot foot glass glass pain pain LH finer semantic coding: Strong activation good for selection and integration/ incorporation when inference completed. RH coarser semantic coding: Increased likelihood of semantic overlap for distant semantic relations, supporting inferences Natural language processing and the right hemisphere Converging data from multiple types of natural language, multiple processes Deriving the gist of stories, making connections, drawing inferences Figurative, nonliteral language Speech production - LH Word interpretation - LH Recovering from misinterpretation - RH Building strong connections – LH (syntax) Finding distant connections – RH (inference, shades of meaning, and…) Higher level language comprehension in action: Figurative language •  Much of language use is figurative, nonliteral •  Jokes, metaphors, idioms, sarcasm •  Does figurative language require different brain processes?...
