Navigating beyond "here & now" affordances-on sensorimotor maturation and "false belief" performance

Area of Science:

• Cognitive Development
• Developmental Psychology
• Theory of Mind

Background:

• Understanding other people's perspectives and beliefs is a complex cognitive ability.
• Research shows toddlers succeed on implicit false belief (FB) tasks but not explicit ones, creating a puzzling discrepancy.
• Existing theories struggle to reconcile these differing performance levels on FB tasks.

Purpose of the Study:

• To propose a novel navigational approach to explain toddlers' differential performance on implicit versus explicit false belief (FB) tasks.
• To introduce a distinction between 'here & now' navigation and 'counterfactual' navigation of FBs.
• To hypothesize the developmental underpinnings of counterfactual navigation.

Main Methods:

• Theoretical proposal of a navigational framework for understanding false belief (FB) acquisition.
• Distinction between navigating FBs relative to current affordances versus non-actualized relations.
• Hypothesizing the role of developing 'sensorimotor priors' in enabling counterfactual navigation.

Main Results:

• Toddlers can navigate FBs within their immediate, concrete 'here & now' affordance space.
• Toddlers appear unable to navigate FBs in abstraction from concrete affordances, a requirement for explicit FB tasks.
• The proposed model aligns with empirical findings on FB task performance and developmental timelines.

Conclusions:

• The ability to understand false beliefs (FBs) develops through distinct navigational capacities.
• 'Here & now' navigation, tied to immediate affordances, is accessible early.
• 'Counterfactual' navigation, requiring abstraction from the present, emerges later, likely linked to the maturation of sensorimotor priors around age four.
