RHD - Coggle Diagram
RHD
RH role in
Producing automatic phrases, sequences, profanities (nonpropositional speech)
Lexical-semantic processing as words processed: Intact RH activates peripheral meanings eg. snow white, rotten when you think of apple aka coarse coding
Coarse coding impairments may underlie RHD difficulties w nonliteral lang interpretation, discourse integration, inference generation, semantic reanalysis (when listener needs to interpret)
Mediating paraling and pragmatic aspects that accompany the words of an utterance that can change/influence its meaning
Discourse processing eg. cohesion (drawing tgt separate elements)
Prosodic processing- pitch discrimination, flattened intonation, X judge emotional tone in others' speech
Affective processing: flattened affect-sound disengaged even when they are not, X judge others' affect/body lang
General chars
Appear to have appropriate, adeq ling skills can converse at superficial lvl. Sentence structure ok, sth off but hard to pinpoint
Lack of affect
Denial physical disabilities
Difficulty recognising friends, relatives (prosopagnosia)
Inappropriate humour
Tend to itemise > interpret info
Case study: too much background info, circumlocution, no real flow, verbose, tangential, digress from qn and is aware about it, repetition
Neuropath
Stroke
Tumours
Head injury
Disease processes eg.HIV
BUT detailed knowledge of localisation of language, comm processes within RH is currently lacking
Language localisation
90% of ppl are right handed
95% of right handed ppl have left hemispheric lang dominance (Our lecture series focuses on this!)
75% of left handed ppl have left hemispheric lang dominance (Interesting!)
25% of left handed ppl have right hemispheric/bilateral lang dominance
Contributions to comm in daily life
Social comm demands complex, inter-related cognitive, communicative abilities
Can have detrimental effects on social participation: returning to work, leisure, social skills, r/s bcos they X express mood
It may bring concerns: person's lack of awareness of own limiations, trouble recognising friends, poor turn-taking (will dominate convos), tend to digress, impulsive and sometimes X appropriate responses
What SLP sees
Person with RHD may present w dysphagia and/or dysarthria
Obsv of person's different and at times inapprorpriate comm behaviour
Role of SLP
Knowledge of other professionals as our role w comm and scope of this role
Increased focus on role of cognitive functions in lang operations, pragmatics, investigating deeper problems of syntax
Increased focus on social conseq of comm disability
Use of WHO ICF as Ax and Tx
Left vs. right brain functions
Left:
logical, facts, rules, analytical, objective, parts oriented, words and lang, past and present, math and science, order/pattern perception, knows object name, forms strategies, verbal, literal, practical, safe
Right:
intuitive, imagination, synthesising, "big picture oriented", symbols, images, present and future, philo, religion, spatial perception, knows object function, presents possibilities, prosodic, pragmatic, nonliteral, impetuous, risk taking
Lack consistent accepted label creates difficulties in comm about disorders, blurry for what is considered normal bcos depends on their premorbid condition
