- What are the causes of abnormal behavior?
-
1. deviant structure and function
2. learning of deviant ideas
3. brain pathology - What are the 3 different "brain functional organizations"?
-
1. left and right hemisphere "traditional" organization
2. bottom-up, phylogenetic organization
3. anterior brain - posterior brain organization - Dominant Hemisphere (4 styles?)
- (direct opposite of non-dom hemi)...detailed-oriented, processes information in a stepwise fashion, logical, subserves social emotions (pride, gratitude)
- Non-Dominant Hemisphere (4 styles?)
- (direct opposite of dom hemi)...gestalt oriented, processes information in multiple channels, creative, subserves primary emotion (anger, anxiety)
- Dominant hemisphere handles...? (4)
-
-language
-verbal learning and memory
-verbal reasoning and planning
-complex learned fine hand movements - Non-Dominant hemisphere handles...? (3)
-
-prosody (emotional and gesturing components of language)
