BCIA Psychophysiological Assessment and Profiling

Question 1

A psychophysiological stress profile (PSP) involves measuring multiple physiological channels:

Accepted Answer

At baseline, during stressor tasks, and during recovery phases

Answer

Only during maximum physical exertion

Answer

Exclusively during sleep stages

Answer

Only with the client's eyes open under bright lighting

Question 2

Which of the following is NOT a standard physiological channel in a typical BCIA psychophysiological assessment?

Accepted Answer

Intramuscular needle EMG

Answer

Surface EMG (frontalis or trapezius)

Answer

Skin conductance (GSR)

Answer

Peripheral skin temperature

Question 3

In psychophysiological assessment, 'recovery' refers to:

Accepted Answer

The return of physiological measures toward pre-stress baseline levels after a stressor is removed

Answer

The increase in physiological arousal following relaxation

Answer

Only the restoration of EEG alpha after a cognitive task

Answer

The practitioner's post-session documentation process

Question 4

What does 'lability' mean in the context of psychophysiological profiling?

Accepted Answer

The tendency of a physiological measure to fluctuate or change rapidly over time

Answer

The absolute amplitude of a physiological response

Answer

A stable resting baseline with no variation

Answer

The maximum value achieved during a stress task

Question 5

During a psychophysiological stress profile, a client shows elevated frontalis EMG during mental arithmetic that does not return to baseline after 2 minutes. This most likely indicates:

Accepted Answer

Slow or incomplete autonomic/muscular recovery, suggesting poor stress resilience in that system

Answer

Normal recovery for all clinical populations

Answer

Artifact from electrode movement

Answer

Optimal frontalis muscle tone

Question 6

The concept of 'autonomic balance' in psychophysiological assessment is best measured by:

Accepted Answer

The ratio of sympathetic to parasympathetic indices, such as LF/HF ratio in HRV

Answer

Peak EMG amplitude during maximum voluntary contraction

Answer

Absolute skin temperature at rest

Answer

The number of phasic GSR responses per minute at rest
