PSYC31H3 Chapter Notes - Chapter 9: Spatial Disorientation, Mental Status Examination, Memory Span
Document Summary
Examination, sensitivity to dementia ranged from 46% to 69% while the range for speci city (for normal cognition) was from 93% to 95%, showing that time orientation is more predictive of normal cognition than dementia. Digits backward: the number sequences of the wechsler intelligence and memory scales are two to eight and two to seven digits long, respectively, on hearing the digits, the subject"s task is to repeat them in exactly reversed order. Test characteristics: the normal raw score difference between digits forward and digits reversed tends to range a little above. If forward was misspelled, the misspelling became what was supposed to be reversed world became a part of the mini-mental state. Concentration/focused attention: vigilance tests examine the ability to focus and sustain attention for detecting target stimuli. Processing speed: many cognitive operations require suf cient information processing speed for relevant operations to be executed within the time allowed, slow processing speed often underlies attentional de cits.
