Investigating prefrontal working memory limits, sensory memory decay rates, and spatial chunking strategies.
Formulated by cognitive psychologist George Miller in 1956, Miller's Law states that the number of objects an average human can hold in working memory is 7 ± 2. This limit applies to immediate recall tasks (sensory buffer registers) and is governed by prefrontal cortical circuit sizes.
High-performance memory scores are achieved by chunking individual items into consolidated logical units. In a spatial grid test, this involves grouping coordinate sequences into visual lines, polygons, or motion trajectories, mapping multiple variables into a single conceptual unit.
While absolute working memory capacity is highly correlated with genetics, you can significantly optimize effective recall through chunking techniques and spatial associations.
Short-term memory refers strictly to the passive storage of information, while working memory involves both storage and active manipulation of those data points.
