Attention, Lang And Lateralisation Flashcards
Commissures
Small bands of axons
Contralateral connections
Left hemisphere controls right side and vis versa
Lateralisation
Certain processes are more highly developed on one side of the brain
Left hemisphere dominance
Specialised for language
Right hemisphere dominance
Specialised for emotional content, face recognition and spatial ability
Right hemisphere hypothesis
Right hemisphere dominant for emotion recognition (coincides with traditional view)
Valence hypothesis
Right hemisphere dominant for negative emotions, left for positive emotions (Davidson, 1982)
Damage to right hemisphere
Right parietal cortex- neglect of body on left side
Right temporal cortex - neglect of surroundings on left side
Split brain patients
Is corpus callosum is cut, no connection between hemispheres
Corpus callosum
Network of axons
Lungs produce aerodynamic energy…
Larynx, transform this into sound waves
Lieberman 1984.. Larynx position
Only humans speak even though speech is produced similarly to vocalisations of non human animals because the larynx is in a lower position - more flexibility
3 speech/Lang components
Semantics- significance (meaning)
Syntax - rules and principles (grammar)
Prosody - rhythm, stress and intonation (melody)
Brocas and wernickes areas positions
Broca - left frontal cortex
Wernickes - left temporal cortex
Broca’s area
Language production (speaking, writing, gestures) Comprehending complex sentences (grammar)
