  1. A psychologist uses a computerized version of the Continuous Performance Test (CPT). The test manual specifies a minimum monitor refresh rate of 60 Hz. What happens if a 50 Hz monitor is used?

    Answer: Stimulus timing may be inaccurate, invalidating response-time dependent scores

    CPT stimulus duration and inter-stimulus intervals are synchronized to monitor refresh rate; a lower-than-specified rate distorts timing and invalidates reaction-time norms.

  2. Which of the following BEST describes the purpose of 'impedance matching' in psychophysiological recording equipment?

    Answer: Optimizing signal transfer between biological source and amplifier input to minimize signal distortion

    Impedance matching ensures maximum signal transfer efficiency from the biological source to the amplifier, reducing noise and distortion in psychophysiological recordings.

  3. A psychologist discovers that a client's assessment data stored on a clinic server has not been backed up for 6 months due to a failed automated backup job. What is the MOST appropriate immediate action?

    Answer: Perform an immediate manual backup, fix the automated backup configuration, and document the lapse

    An immediate manual backup protects existing data, restoring the automated backup and documenting the lapse fulfills both data integrity and HIPAA breach-prevention responsibilities.

  4. When replacing electrode gel in a GSR/EEG device reservoir, a psychologist should MOST importantly ensure that:

    Answer: The replacement gel has the same conductivity specifications as recommended by the manufacturer

    Using gel with incorrect conductivity alters electrode-skin impedance, introducing noise and rendering psychophysiological measurements non-comparable across sessions.

  5. A practice adopts a new electronic health records (EHR) system that integrates with psychological testing software. Before going live, what is MOST critical from an equipment-operations standpoint?

    Answer: Conducting integration testing with sample (de-identified) data to confirm data transfer accuracy and system compatibility

    Integration testing with de-identified data verifies that assessment scores, reports, and demographic fields transfer correctly and that the two systems are fully compatible before storing real PHI.

  6. A psychologist's transcranial direct current stimulation (tDCS) device used in research displays an error code indicating current delivery is outside the programmed range. The SAFEST response is to:

    Answer: Immediately terminate the session, remove the device from service, and have it inspected by a qualified technician before further use

    An out-of-range current error indicates a hardware fault that could deliver unsafe stimulation levels; the device must be inspected before further clinical or research use.

  7. Which regulatory standard MOST directly governs the electrical safety requirements for biofeedback and psychophysiological devices used in clinical settings in the United States?

    Answer: IEC 60601-1 medical electrical equipment safety standard, adopted by the FDA for medical device clearance

    IEC 60601-1 is the internationally recognized standard for medical electrical equipment safety that the FDA uses as the basis for evaluating biofeedback and psychophysiological device clearance in the US.
