Working memory is the cognitive workspace where thinking happens. Unlike long-term memory (passive storage), working memory is the active scratchpad for reasoning, problem-solving, and language comprehension.
Capacity is limited: research consistently shows 4 ± 1 chunks of information can be held in working memory at once (Cowan, 2001 — refining Miller's original "7±2" estimate).
Working memory predicts academic achievement, reasoning ability, and learning rate better than IQ in many studies (Alloway & Alloway, 2010). Critically, it is trainable: Basak et al. (2008) found g ≈ 0.28 effect size for working memory training transferring to cognitive performance in older adults.
MindFrame's working memory challenges train capacity, attention control, and the ability to hold multiple competing hypotheses in mind simultaneously — a core component of sophisticated reasoning.
