Choice autonomy and memory for spatial locations in six-year-old children

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Spatial memory development in children is crucial for navigation and learning.
• Understanding memory errors, such as Across-Trial Memory (ATM) and Within-Trial Memory (WTM) errors, is key to cognitive development.
• The impact of environmental interaction and choice on spatial memory has been a focus of research.

Purpose of the Study:

• To investigate the effect of freedom of choice on spatial memory performance in six-year-old children.
• To differentiate the impact of choice on Across-Trial Memory (ATM) and Within-Trial Memory (WTM) errors.
• To examine how training duration and mode of transport (walking vs. wheelchair) influence spatial memory.

Main Methods:

• Six-year-old children participated in a 9-day training study involving a spatial search task with rewards.
• Participants were assigned to groups with varying degrees of freedom of choice and modes of transport.
• Performance was assessed by measuring Across-Trial Memory (ATM) and Within-Trial Memory (WTM) errors during training and testing phases.

Main Results:

• Children allowed freedom of choice showed significant improvement in spatial memory across training days.
• Groups with free choice demonstrated superior performance at testing compared to non-choosing groups.
• Across-Trial Memory (ATM) errors were significantly lower in groups with free choice, while Within-Trial Memory (WTM) accuracy did not differ.

Conclusions:

• Freedom of choice enhances spatial memory by promoting better environmental segmentation.
• Within-Trial Memory (WTM) appears less affected by training or environmental familiarity compared to Across-Trial Memory (ATM).
• Environmental interaction and the ability to make choices are critical factors in developing accurate spatial memory strategies.
