Description

An online task (built with PsychoJs, run on Pavlovia) in which participants learn the results of 8 novel numeric facts presented with the nonexistent operator '&' (e.g., "3&8 = 29"), using only single-digit operands and 2-digit results with digits 2–9. Performance is quantified by a recall score where a correct result digit in the correct position scored 1 point and each correct digit in the incorrect position scored 0.5, scaled 0–100, plus response times and forced-choice tests with confidence ratings. It was used to mimic numeric fact learning in adults already familiar with elementary arithmetic.

Design Implications

Context

Requirements

  • Participants already familiar with elementary arithmetic; facts generated with low between-fact similarity to avoid disrupting learning

Constraints

  • The facts are arbitrary with no systematic rule, so the task isolates rote memorization rather than conceptual or rule-based arithmetic learning

Target Learners

  • Adults (ages 20-40) familiar with elementary arithmetic

Learning Goals

  • Memorization and rapid, accurate retrieval of numeric facts
