Exam 15: Extension: B - The Temporal Lobes
Choose one standard clinical neuropsychological test used to assess temporal lobe function, and describe it in some detail. Identify the specific cognitive function it is intended to evaluate.
Answer Key
The Rey Complex-Figure Test uses a geometric figure with multiple components. Patients initially are instructed to copy the figure. After a forty-five-minute delay (where there are usually intervening assessments administered), patients are then reminded of the figure and instructed to draw it from memory as best they can. This test has been useful in the assessment of nonverbal memory as well as hemispatial neglect (attention). Additionally, patients with differing clinical pathologies have been shown to make specific types of spatial errors.
Distinguish between loudness and timbre.
Loudness is the amplitude of the sound and subjectively described as loud or very loud, soft or very soft, and so on. The timbre of a sound refers to that distinct aspect of a particular sound-for instance, the distinct quality of a saxophone versus a clarinet when both may be at the same loudness and pitch.
Argue the case that the temporal lobe participates in the appreciation of contextual information.
Patients with right-hemisphere lobectomies demonstrate impairment on the McGill Picture-Anomalies Test. They have no difficulty in accurately describing the scenes they are viewing but are unable to identify those items that would be out of context.
Identify the five projection pathways of neuronal connections in the temporal lobe of the monkey.
Describe the effects of right temporal lobe lesions, including on the primary auditory cortex, on pitch perception.
