Definition

PSV indicates a tendency to repeat the same approach or remain fixed on a prior pattern during processing. In interpretation, it functions as a sign of rigidity, difficulty shifting focus, or inefficient attentional control.

Interpretation

When PSV is present, it is worth checking whether the record shows less flexibility in changing strategy.
PSV combined with other inefficiency indicators strengthens the reading of rigid processing.
In some records, even a single PSV deserves attention because the variable is meant to capture genuine perseveration.

Cautions

PSV is not the same as normal consistency or stylistic preference.
The value needs protocol context and the exact form of the coded perseveration.
It should not be overread without reviewing Zd, DQ, and other signs of organization.

Cross References

PSV is a warning sign, not a diagnosis by itself.
It should be read with Zd, DQ+, DQv, WSum6, and X-%.
