C J Long
Misconceptions and ill founced assumptions underlying clinical application of Neuropsycholgical Procedures.
- Good clinical decisions are based on psychometrics.
- Symptom characteristics and Demographics often provide essential data -- yet these data are not incorporated in statistical analyses.
- Emotional factors interact with cognitive measures in ways that are not yet clearly understood.
- There is almost always a lack of homogenous subgroups.
- Tests do not contribute equally to clinical decisions.
- Sound research and sound medical diagnosis - not made from test data -- Rather, hypothesis are formulated and the data are used to support or refute. (It would appear that the same is true for neuropsychological decisions.
- Can't function effectively looking up scores in tables.
- Can't perform regression mentally.
- Can't avoid biases (frequency / recency).
- Can't improve unless arrange for feedback regarding decisions.
*Must avoid assumptions in the absence of data. (Hypothesis testing).*
