The development of self-initiated visuo-spatial working memory.

Area of Science:

• Cognitive Development
• Neuroscience
• Psychology

Background:

• Visuo-spatial working memory (VSWM) research traditionally uses tasks where children lack control over memory content.
• Everyday memory often involves active selection of information for encoding.
• The development of self-initiated (SI) VSWM in children remains under-explored.

Purpose of the Study:

• To investigate the development of self-initiated (SI) visuo-spatial working memory (VSWM) in children aged 7 to 10 years.
• To examine whether children strategically impose spatial structure on memory representations.
• To compare memory performance in self-initiated versus externally provided conditions.

Main Methods:

• Two modified span tasks were employed: one with spatial locations and another with object pictures.
• Participants either selected their own memory targets (SI condition) or were given random targets.
• Spatial structure of memory representations was analyzed for path length, crossings, and linearity.

Main Results:

• Children in the SI condition constructed more spatially structured representations than in the provided condition.
• This included shorter paths, fewer crossings, and more linear shapes in spatial sequences.
• Self-initiation significantly improved overall memory performance, particularly in more demanding tasks.

Conclusions:

• 7- to 10-year-old children possess metacognitive awareness of VSWM spatial structure.
• They strategically apply this knowledge during encoding to enhance memory recall.
• SI VSWM demonstrates children's ability to actively shape their environment for improved cognitive functioning.
