SCAFFOLDING EFFECT

psychology

Visualize set relationships. When discussing relationships such as "both A and B" or "A but not B", draw a Venn diagram for intuitive presentation.

anchor

Anchor fast decisions

Use overlapping closed curves in a plane to represent sets and their relationships; the overlapping region is the intersection, the non-overlapping exterior is the complement, and the overall coverage is the union; intuitively present the logical structure of "and/or/not".
