PSYC32H3 Chapter Notes - Chapter 10: Attention, Hemianopsia, Prosopagnosia
Document Summary
Understanding of which functions are impaired & how they are manifested ! Testing each function in diff modalities, combo with diff functions, under diff conditions - gain. Brain impairment involving one visual function will affect cluster of functions ! Both hemisphere at work - even when stimuli are pictures - we still attach words to pictures ! Absence of awareness of visual stimuli in left eld of vision - re ects rh lesions (more likely. Rh damage can disrupt attention networks throughout brain - inattention may be relate to in posterior regions - parietal lobe)! pathologic disruption of white matter connections with parietal cortex than precise location of a lesion! Hemianopsia: blindness over half of eld of vision! Apt to be apparent during acute stages of sudden onset condition (stroke/trauma)! One trial each hand! centre, top & bottom line used for instructions - turn paper 180, keep non drawing hand off, make 1 mark each line without skipping nay lines!
