Toponymy is the discipline that studies place names: their origins, meanings, evolution, and classification across languages and cultures. Parameters: (1) source — toponyms derive from natural features, personal names, events, or prior toponyms; (2) morpholog…
The base-rate fallacy is the cognitive error of neglecting prior probability (the base rate) when evaluating conditional evidence, overweighting specific case information at the expense of population-level statistics. Parameters: (1) base rate — the prior fre…
A concept map is a two-dimensional diagram that represents organized knowledge as a network of labeled nodes (concepts) connected by directed arcs (propositional relationships). Each arc carries a linking phrase that forms a meaningful proposition with its co…
Labeling is the human-made act of attaching a word, symbol, or mark to an object, idea, or category to enable identification, sorting, and communication. Parameters: (1) the label must be a human-created sign — not a natural property; (2) the attachment must…
Recursion is the practice of defining a procedure, structure, or rule in terms of itself — a function that calls itself, a pattern that contains smaller copies of itself, or a definition that references the term being defined. The mechanism persists through f…
Transduction is the deliberate conversion of a signal, datum, or energy form into another type while preserving its informational content. The operator takes inputs in one representational or physical modality and produces outputs in a different modality, map…
The testing effect is the empirically established finding that retrieving information through a test (production format, not recognition) produces a stronger long-term retention gain than equivalent study time spent re-reading or highlighting. Parameters: (1)…
Folksonomy is a human-made system of classification produced organically by collective user tagging rather than by expert taxonomy. In a folksonomy, any community member assigns free-form labels (tags) to shared artifacts (photos, articles, documents), and th…
