PSYC 360 Study Guide - Midterm Guide: Ageusia, Transcranial Magnetic Stimulation, Attention Deficit Hyperactivity Disorder
Document Summary
Loss of representation of contralateral visual field in both eyes: e. g. , hemianopsis = scotoma covering half of the visual field. *agnosia = a failure of recognition that is not attributable to a sensory deficit or to verbal or intellectual impairment: e. g. , r. p. is deficient in recognizing all objects with complex curved surfaces, not just faces. Intact dorsal stream allows unconscious face recognition (larger skin conductance response to familiar faces) Inability to see smooth progression of movement: can be triggered by antidepressants, mt neuron has a large binocular receptive field to track movement over a wide range. Apperceptive agnosia: damage to inferotemporal cortex (ventral stream, visual perceptual deficits (cannot see object parts as a unified whole, cannot draw by copying but can identify objects verbally. Associative agnosia: damage to inferotemporal cortex (ventral stream) Impaired association of visual perception with more general, sematic knowledge (cannot interpret, understand, or assign meaning to objects: can draw by copying but cannot identify objects verbally.
