BCIA Psychophysiological Assessment and Profiling 2

Question 1

Which standardized cognitive stressor is most commonly used in psychophysiological stress profiling?

Accepted Answer

Serial subtraction (mental arithmetic) task

Answer

Serial subtraction (e.g., counting backward by 7 from 500) is a widely used standardized mental stressor in psychophysiological profiling, reliably activating the sympathetic nervous system.

Question 2

In a comprehensive intake assessment, a biofeedback practitioner should routinely ask about medications because:

Accepted Answer

Many medications (beta-blockers, anxiolytics, antidepressants) significantly affect HRV, EMG, and other biofeedback measures

Answer

Medications such as beta-blockers reduce HRV and heart rate reactivity, while benzodiazepines alter EEG patterns. Knowing a client's medications is essential for accurate interpretation of biofeedback data.

Question 3

A biofeedback intake that includes the Symptom Checklist-90 (SCL-90) or Brief Symptom Inventory (BSI) serves which purpose?

Accepted Answer

Providing standardized psychometric data to track symptom change and inform treatment planning

Answer

Standardized self-report measures like the SCL-90/BSI provide psychometric baseline data, help track symptom changes over treatment, and contextualize physiological findings within clinical presentation.

Question 4

The 'orienting response' in psychophysiological assessment refers to:

Accepted Answer

A brief, transient physiological reaction (e.g., GSR spike, heart rate deceleration) to a novel stimulus

Answer

The orienting response is a brief, multi-channel physiological reaction to novelty — often seen as a GSR spike or heart rate change. It habituates with repeated stimulus exposure and must be distinguished from stress responses.

Question 5

For valid psychophysiological data collection, which environmental factor must be controlled?

Accepted Answer

Room temperature, noise level, and lighting (to avoid confounding baseline measures)

Answer

Environmental factors such as room temperature, ambient noise, and lighting directly affect skin temperature, GSR, and arousal measures. Standardizing the environment is critical for valid baseline comparisons.
