[Coding/Special Scores] PSV

Aliases

• PSV
• perseveration
• perseverative responding

Definition

PSV is coded when the subject perseverates and repeats the same response or same kind of response in a rigid way.
It does not refer to simple consistency; it points to stereotyped or mechanical repetition.

Conditions

• Consider it when the same response or a very close pattern is repeated perseveratively.
• It may appear within the same card or across multiple cards.
• The important point is not simple similarity alone, but the quality of rigid repetition.
• The later interpretive meaning connects with result-interpretation/lower-section/processing/PSV.

Cautions

• A similar response based on economy or preference is not enough by itself for PSV.
• Coding requires insistent or mechanical repetition, not merely a stable style.
• PSV marks the presence of perseveration; it does not by itself explain its cause.
