PSYB65H3 Chapter 15: Chapter 15
Document Summary
Chapter 15: the temporal lobes: typical temporal-lobe disorder symptoms include radical changes in personality and affect, memory disturbance, and at least a transient disturbance of language. Affective responses: affective response is a function of the amygdala, damage can cause lack of emotional reactions and not recognizing threatening stimuli. Visual processing in the temporal lobe: the ventral stream of visual processing is performed by several discrete visual regions including specialized facial and object-recognition zone, fusiform face area activated for faces, and parahippocampal place area for scenes. Language processing requires analysis of rapid changes in sounds (left temporal lobe); while differences in frequency are critical for music (right temporal lobe). Damage to auditory regions causes language recognition de cits (primary left), and music (primarily right), as well as in sound localization. Changes in sexual behaviour: a classic symptom of bilateral temporal-lobe damage that includes the amygdala is a release of sexual behaviour; this is not observed in unilateral injury.
