Three- but not 2-year-olds misinform others spontaneously in an interaction-based task.

Area of Science:

• Developmental Psychology
• Cognitive Science
• Linguistics

Background:

• Children's spontaneous communication, including informing, develops early.
• The emergence and nature of spontaneous deceptive communication, such as misinforming, in young children remain less understood.
• Misinforming is considered a key indicator of implicit false belief understanding.

Purpose of the Study:

• To investigate if children who spontaneously inform also deliberately misinform others in uninstructed interactions.
• To examine the developmental trajectory of spontaneous informing versus misinforming in early childhood.
• To explore the relationship between spontaneous communication behaviors and implicit false belief understanding.

Main Methods:

• A simplified, anticipatory, and interactive paradigm was employed using puppet characters.
• Children interacted with a protagonist puppet that hid an object, followed by a friend or competitor puppet searching for it.
• Children's spontaneous actions to inform or misinform the searching puppets were recorded and analyzed across two experiments.

Main Results:

• Two-year-olds spontaneously informed the puppet friend but did not selectively misinform the competitor.
• Three-year-olds, in contrast, demonstrated spontaneous misinforming abilities within the same experimental paradigm.
• The findings suggest informing, but not misinforming, is an early developing spontaneous communication skill.

Conclusions:

• Spontaneous informing appears earlier in development than spontaneous misinforming.
• The study suggests a conceptual distinction in the development of communication strategies, with informing and misinforming having different developmental timelines.
• These findings raise questions about the direct link between early interactive communication and implicit false belief understanding.
