MARSHMELLOW EXPERIMENT

Research Methodology: The Biscuit Box False Belief Task

​Overview

​The Biscuit Box False Belief Task is a standard developmental psychology procedure used to assess Theory of Mind  in children, typically between the ages of 3 and 7. Unlike the Marshmallow Experiment, which focuses on impulse control, this task evaluates a child’s cognitive ability to attribute "false beliefs" to others.

​Core Objective

​The primary goal is to determine at what age a child understands that another person can hold a belief that contradicts reality. This transition marks a significant milestone in social cognition and empathy development

The child predicts that their friend will know there are crayons inside. They struggle to separate their own current knowledge from what another person could possibly know.

​Passed Task : The child recognizes that their friend will have a "false belief" and will expect biscuits. This demonstrates that the child understands that the mind represents the world, and those representations can sometimes be incorrect.
