9.2 Right Hemisphere Damage and Communication Flashcards
RHD deficits are usually in..
- figurative/nonliteral language
- inferencing
- discourse/pragmatics
what may figurative/nonliteral deficits look like?
misinterpretation of nonliteral language
can directly and indirectly make requests but often cannot justify or provide explanation for request
deficit in formulaic language (left formulaic expressions used with RHD compared with LHD)
what may deficits in inferencing look like?
difficulty when a situation requires elaborative inferences
difficulty when situation has multiple potential interpretations
suppression deficit hypothesis: can generate several interpretations but inability to suppress the less likely ones
difficulty with understanding an interpreting: humor, sarcasm, literally false statements/white lies
can not understand emotions for s a story character, family member, etc. when different from his or her own emotion
what may deficit in discourse/pragmatics look like?
egocentric talk
tangential/off-topic/irrelevant content
disorganized narratives
reduced ability to ID and repair conversational breakdowns
reduced ability to judge appropriateness of conversation
*these elements become worse with less structure*
confabulations– lying without knowing it
theory of mind is disrupted
what is theory of mind?
ability to step into someone else’s shoes mentally
what are the diagnostic options for RHD?
cognitive-communicative disorder/impairment
cognitive-linguistic impairment/disorder
what is one issue with most RHD tests
they are not sensitive enough to detect subtle changes in higher-level discourse
many RHD impairments are due to
inefficient processing, NOT inability to process
were may you see breakdowns when assessing a RHD patient?
when you tax the system.
when giving them a basically structured task they will do well but when you start to do more complicated tasks, you will see the breakdown.

examples of assessment methods for RHD
informal: narratives, biography, conversation, story-retell, picture description
in informal assessment, write specific descriptions of deficits,”off” responses, etc.
unfortunately, treatment for RHD is
understudied and lacking empirical research
treatment options for RHD
metaphor comprehension - emphasizing use of context rather than general multiple meanings
focus on contextual cues to facilitate comprehension of situations
training patient to use internal cuing
what is dysprosody
difficulty in comprehension or use of prosody to signal linguistic boundaries, meaning, convey meaning
what is aprosodia?
the difficulty in the comprehension of or the use of prosody to signal linguistic boundaries,to provide additional meaning, to convey emotions.
