- What is Biopsychology?
- Neuroscience
- Study of the nervous system e.g. neuroanatomy
- Biopsychology
- Knowledge from neuroscienceapplied to behaviour
- Human vs non-human experiments
- Human
- Can follow instructions
- Report subjective experiences
- Often less expensive
- Non-human
- Can use comparative cross species approach
- Differences are more quantitative
- Simpler nervous system and brain
- Could be greater ethical issues
- Human
- Experiments vs non-experiments
- Experiments
- Establish cause and effect
- Essential to scientific discovery
- Paradoxicallyvery simple e.g. two or more conditions
- Non-experiments
- High ecological validity - exposed to conditions in real world
- Confounding variables have not been controlled
- Experiments
- Pure vs applied research
- Pure
- Motivated by curiosity of the researcher
- Establishes concepts that could provide information for many problems
- Purpose of acquiring knowledge
- Applied
- Brings about a direct benefit
- Pure
- Branches of Biopsychology
- Physiological Psychology
- Direct manipulation of the nervous system e.g. lesions
-
Psychopharamacology
- Nervous system manipulated pharmacologically (i.e. drugs)
- Neuropsychology
- Behavioural deficits produced by brain damage
- Psychophysiology
- How physiology affects behaviour e.g. EEG
- Cognitive psychology
- Neural bases of cognitive processes e.g. memory
- Comparative psychology
- Study of evolutionary and genetic factors of behaviour
- Physiological Psychology
- Converging operations
- Using multiple approaches to address a single question e.g. whether Korsakoff's syndrome is a result of toxic effects of alcohol on the brain
- Case studies such as Jimmie G suggested that korsakoff's was caused by alcohol
- He could not form new memories and believed he was still in the navy
- Converging operations found that korsakoff's was due to thiamine deficiency and is just accelerated by alcohol intake
- Thiamine-deficient rats exhibited memory deficits and brain damage similar to alcoholics (Mumby et al.)
- Thiamine-deficient rats exhibited memory deficits and brain damage similar to alcoholics (Mumby et al.)
- Alcoholics counselled to stop drinking and treated with large doses of thiamine
- Case studies such as Jimmie G suggested that korsakoff's was caused by alcohol
- Using multiple approaches to address a single question e.g. whether Korsakoff's syndrome is a result of toxic effects of alcohol on the brain
