Fast mapping is an incidental learning paradigm that presents a novel word and new item alongside a familiar "supporting foil," allowing the learner to infer (and possibly learn) the meaning of the new word. While fast mapping is well studied in children, its role in adult learning remains debated, with studies reporting robust effects and null results. This paper reports a meta-analysis of behavioral fast mapping studies in healthy adults. Across 28 experiments, fast mapping produced a significant overall medium effect (Hedges' g = 0.39) on memory outcomes. This was observed to a similar extent across three theoretically motivated categories: (1) interaction with existing memory traces, (2) stability over time, and (3) moderation by semantic features. The meta-analytic findings converge on the conclusion that fast mapping can facilitate integration into memory, likely through schema-based mechanisms, with a need to clarify boundary conditions through further experimentation.

The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...
