Classification & Assessment in Clinical Psychology

Set C

Electrocardio-gram (ECG)

A psychophysiological measurement technique used for measuring heart rate.

Electroen-cephalogram (EEG)

A psychophysiological assessment measure that involves electrodes being attached to the scalp to record underlying electrical activity and help localise unusual brain patterns in different brain areas.

Electrodermal Responding

A psychophysiological measure using electrodes attached to fingers of patients to test emotional responses such as anxiety, fear or anger by measuring changes in sweat gland activity.

Functional Magnetic Resonance Imaging (fMRI)

MRI technology which allows brain images to be taken so quickly that tiny changes in brain metabolism can be detected and can provide minute-to-minute information actual brain activity.

Halstead-Reitan Neuro-psychological Test Battery

A common neuropsychological test used across the USA, compiled to evaluate brain and nervous system functioning across a fixed set of eight tests.

Ecological Validity

The extent to which conditions simulated in the laboratory reflect real-life conditions.

Electromyo-gram (EMG)

A psychophysiological measurement technique that measures the electrical activity in muscles.

Face Validity

The idea that a particular assessment method may appear to be valid simply because it has questions which intuitively seem relevant to the trait or charactistic being measured.
