| Question | Answer |
| Galvanic Skin Response GSR | Measures amount of sweat does this by analyzing how quickly a slight of electrical current passes through two points on the skin |
| Electromyography (EMG) | measures muscle activity Does this by estimating the electrical impulses of the muscles during contraction and relaxation. |
| Computerized Topography (CT Scan) | Takes a high resolution x-ray picture of brain (produces static picture) |
| Magnetic Resonance Imaging (MRI) | Uses high radio frequency waves to get picture of brain (produces static picture) |
| Electroencephalogram (EEG) | Electrodes placed on scalp to monitor electrical activity of the brain. EP or evoke potential (when electrical activity is measured in response to a specific stimulus) |
| Positron Emission Tomography (PET Scan) | Slightly radioactive glucose like substance is injected into brain and person is placed into a scanner (active region use up more glucose than inactive ones) |
| Functional Magnetic Resonance imaging (fMRI) | monitors brain activity by tracing blood oxygen levels in brain most detailed |
| Problems with fMRI | timing response time intensive expensive equipment non independence error time of day nervousness of participants |
| non independence error | researcher unintentionally bias their results by not independently selecting which brain areas correlate with certain variables |
| Transcranial Magnetic Stimulation (TMS) | brief electrical current passes through a coil placed on head |
