Chapter 5: Wechsler Memory Scales Flashcards
What is the WMS?
Wechsler Memory Scales, it provides a full range of memory functioning and it is the 9th most frequently used test by clinical psychologists.
What is Explicit Memory?
Facts, descriptive things, it is conscious memory, episodic memory.
What is Implicit Memory?
This is the unconscious memory, and it is procedural memory.
what paints the difference between explicit and implicit memory?
what are the memory components
senory porcessing, working memory, short term memory, long term memory, memory retrieval.
Sensory Processing
visual and auditory
Working Memory
Short Term Memory
Long Term Memory
Memory Retrieval
Mental Memory Complaints
Anxiety, Schizophrenia, Depression, Learning Disorders, Attentional Problems
Physical Memory Complaints
Typically where you would want a neuropsych evaulation. Head Injury, Stroke, Substance use, Neurotoxic exposure, age.
why is it important for clinicians need to be careful in evaluating the impact of these conditions on memory function especially in older populations?
Difference between normal aging and a neurodigenrative disorder.
Russell’s adaptation (1975, 1988)
wasa weak psychometrics that was poorly standardized, and administered logical memory and visual reproduction in immediate and delayed formate. It was called the WMS-R called the WMS revised. wich caused confusion because the APA made the WMS-R as well.
Pschological Association WMS-R was:
the revised version of the WMS and it had 12 subtests, and 5 compositive scores.
what were the weaknesses of the WMS-R of the Psychological Association?
indexes were not good measures of specific memory composnents and there was low reliabilities. The nature of a specific impairment could not be identified.
WMS-III was:
Addressed learning and memory
better reliability than the WMS-R
good internal and test-retest reliability
had a larger population
3 factor model supported by factor analysis: Working memory, Visual Memory, Auditory memory.
There was a differentiation of normal and clinical groups and there was difference between clinical classified individuals and “normal” individuals
Internal Consistency
Content Validity
what is the validity umbrella?
they all fall under the umbrella of construct.
Covergent Validity:
positive correlations with similar tests
Discriminant validity
low or nonexistent correlations with dissimilar tests
Do all subtests and indexes correlate because they measure memory?
Yes.
do you want subtest/index scores of similar abilities to have higher correlations
yes
