[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.
