Dimensions of behaviour:
1)cognition - information handling
receptive functions:
o sensory reception (arousal process) and perception (active processing)
o agnosias: disorders of recognition (impaired perceptual integration)
prosopagnosia: inability to recognize familiar faces
memory and learning
o declarative (explicit) memory: the ability to remember information, objects,
events; it involves awareness
o episodic memory: memories of one’s own experiences
o semantic memory: you understand the concept but don’t necessarily
remember when or where you learned it
o source memory or contextual memory: refers to knowledge of where or
when something was learned
o prospective memory: ability to trigger yourself to remember to do something
in the future
o procedural memory: a habit system (not generally available to conscious
o incidental learning: much information is also acquired without direct effort
(not susceptible to most brain damage)
Neuropsyc test: word stem completion
Stages of Memory Processing
1) Registration or sensory memory neither strictly a memory nor a
perceptual function
2a) Immediate memory (working memory) holds about 7 +/- 2 bits of
information at a time
Neuropsyc test: digit span
2b) Rehearsal (encoding and learning)
Neuropsyc test: CVLT learning trials (can you recall a list of words)
3) Consolidation storing information as long term memory
4) Long term memory (retrieval, which implies consolidation was
5) Recognition (less effortful; implies learning and consolidation)
Amnesia: impaired registration or storage processes
o Anterograde amnesia: inability to remember one’s life events beginning with
the onset of a condition
o Retrograde amnesia: loss of memory for events preceding the onset of brain
o thinking: mental operation that relates two or more bits of information together
explicitly or implicity
expressive functions
o Expressive functions, such as speaking, drawing or writing, manipulating,
