Spatial Organization in Self-Initiated Visual Working Memory.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory

Background:

• Research shows visual working memory (VWM) maintains integrated spatial configurations, even for irrelevant spatial information.
• Existing studies primarily focus on memory for provided information, not self-initiated memory construction.

Purpose of the Study:

• To investigate if individuals construct spatially structured memory representations in self-initiated (SI) VWM tasks.
• To explore the metacognitive control over spatial structuring in SI VWM.

Main Methods:

• Participants engaged in a SI VWM task where they selected visual targets to memorize.
• Two experiments assessed spatial configurations, including proximity, sequence distances, and path crossings.
• Participants described their strategies, and performance was manipulated by asking them to construct configurations for a competitor.

Main Results:

• Participants spontaneously created spatially structured configurations in SI VWM, selecting targets in close proximity and forming efficient sequences.
• Disrupting spatial structure for a competitor demonstrated metacognitive control over spatial organization.
• Explicit verbal reports of strategies focused on non-spatial features (semantic, visual), not spatial structuring.

Conclusions:

• Individuals possess implicit metacognitive knowledge of spatial structure in VWM, which they can manipulate to enhance or impair memory.
• This spatial structuring ability impacts behavior but remains largely unconscious, absent from explicit self-reports.
• The findings highlight active environmental structuring to optimize cognitive performance.
