-Conceptual activities typically involve:
1. Intact system to organize perceptions
2. Well-stocked and readily store of remembered learned material
3. Intact cortical and subcortical interconnections and interaction patterns that underlie thought
4. Capacity to process two or more mental event at a time
5. A response modality sufficiently integrated with central cortical activity to transform conceptual
experiences into behaviour
6. Proper functioning feedback system for continuous monitoring and modulation of output
-it is not unusual to fund executive and conceptual/reasoning deficits occurring together
-concrete thinking is one of the most common signs of impaired conceptual functions
-usually appears as an inability to think in useful generalizations, at the level of ideas, or about
persons, situations, events not immediately present
Concept Formation
-some patients do poorly on virtually all tests of abstract thinking, regardless of mode of presentation or
channel of response
-patients with mild neuropsychological defects may not engage in concrete thinking generally, but may
show deficits on test that test specific aspect of concept formation and reasoning
-concrete thinking takes different forms with different patients, and varies in its effect on mental
efficiency with the type of task
Word Usage Tests
-call for abstract comparisons between two or more words, and provide a sensitive measure of concrete
thinking
-word usage is very dependent upon the integrity of the patient’s communication system and level of
verbal skills. The patient’s verbal skill level must always be taken into account
-difficult items indicate cognitive dysfunction in bright and well educated adults
SIMILARITIES
-subject must explain what each pair of concepts has in common
-concepts range in difficulty from (orange-banana) to (friend-enemy)
-abstract generalizations get a score of two points whereas, specific and concrete responses get a score
of one point
-age related decline beginning at age 70

Document Summary

Intact system to organize perceptions: well-stocked and readily store of remembered learned material, capacity to process two or more mental event at a time, a response modality sufficiently integrated with central cortical activity to transform conceptual. Intact cortical and subcortical interconnections and interaction patterns that underlie thought experiences into behaviour: proper functioning feedback system for continuous monitoring and modulation of output. It is not unusual to fund executive and conceptual/reasoning deficits occurring together. Concrete thinking is one of the most common signs of impaired conceptual functions. Usually appears as an inability to think in useful generalizations, at the level of ideas, or about persons, situations, events not immediately present. Some patients do poorly on virtually all tests of abstract thinking, regardless of mode of presentation or channel of response. Patients with mild neuropsychological defects may not engage in concrete thinking generally, but may show deficits on test that test specific aspect of concept formation and reasoning.
