[Interpretation/Processing] Zd

Aliases

Zd
processing Zd
processing efficiency

Definition

Zd compares the actual level of organizational scanning with the expected level. It is used to estimate whether processing tends to be balanced, excessive, or insufficient.

Interpretation

Values near the expected range suggest a more proportionate scanning and organizing style.
A strongly positive Zd can point to overincorporation or a tendency to take in more than necessary.
A strongly negative Zd can suggest underincorporation or a tendency to move through the field too quickly.
Reading it with PSV helps distinguish inefficiency driven by rigidity from simple perceptual economy.

Cautions

A positive Zd is not automatically better.
A negative Zd does not by itself imply severe impairment.
The value needs context from Zf, PSV, and W:D:Dd.
