Prelim 1 Review Sheet Flashcards
1
Q
Limits to Experimentation
A
- Not everything can be manipulated through random assignment
- Experiments can contain confounds
- Experimentation requires an intentionally constrained, controlled, often artificial environment
2
Q
Methods involving human brain
A
- Measuring brain activity associated with thoughts/behaviors (correlation)
- Naturally-occurring lesions from accidents/disease (quasi-experiment)
- Direct brain stimulation (experimental manipulation)
3
Q
Electroencephalography (EEG)
A
- measures electrical activity in the brain
- good temporal resolution
- poor spatial resolution
- non-intrusive
4
Q
Functional Magnetic Resonance Imaging (fMRI)
A
- measure of blood flow to areas of brain
- correlation
- decent spatial resolution
- poor temporal resolution
- expensive, uncomfortable
5
Q
Transcranial Magnetic Stimulation (TMS)
A
- Electromagnetic induction over scalp
- disrupts neuronal activity in targeted region
- penetration is limited to 5-6cm deep
- minor side-effects
6
Q
Developmental Methods
A
- Cross-sectional (3y olds vs 5y olds)
- Longitudinal (look at kids at 3y, then again at 5y)
- Twin studies (identical vs fraternal, reared together vs reared apart)
