- Biological Approach
- Weaknesses
- Bad temporal resolution
- No functional detail
- Loud banging noise
- No metal - practical issue
- Relating to behaviour - normally relate brain activity to behaviour
- Research Methods
- EEG Scans
- Records electrical activity
- Strengths
- Safe and painless
- Good temptoral resolutions
- Ease of relating behaviour to acticity
- Weaknesses
- Not good structural detail
- Strengths
- Records electrical activity
- Post Mortem Investigations
- Looking at brain after death
- Strengths
- Good structural detail
- Large scale - by eye
- Small scale - lookig at tissues through microscope
- Good structural detail
- Weaknesses
- No temproal resolutions (brain is not functions)
- No functional detail (brain non-functioning)
- Can't link to behaviour directly (person is deceased)
- Can ask family members
- Need order from coroner's and consent from family
- Strengths
- Looking at brain after death
- PET Scans
- Detects radioactive decay in parts of the brain
- Strengths
- Not much distress to patient
- Good temporal resolution
- Has timescale
- Good functional detail
- Weaknesses
- Patients have to stay still - uncomfortable
- Long procedure
- No structural detail
- Strengths
- Detects radioactive decay in parts of the brain
- MRI scans
- Detects radio frequency signals
- Strengths
- Good structural detail
- Weaknesses
- Bad temporal resolution
- No functional detail
- Loud banging noise
- No metal - practical issue
- Relating to behaviour - normally relate brain activity to behaviour
- Strengths
- Detects radio frequency signals
- EEG Scans
- Assumptions
- Human behavious is strongly influenced by our genetic makeup and our genetic inheritance
- CNS is essantial for thought and behaviour
- Structure of brain can explain thought and behaviour
- Chemical processes are responsible for psychological function in the brain
- imbalance of chemicals can cause psychological disorders
- Humans have evolved biologically
- Darwin's Theory
- We have a lot in common with other animal;s
- Darwin's Theory
- Weaknesses
- Good functional detail
- Strengths
- Safe and painless
- Good temptoral resolutions
- Ease of relating behaviour to acticity
- Strengths
