Humour from 12 to 36 months: Insights into children's socio-cognitive and language development

Area of Science:

• Developmental Psychology
• Linguistics
• Cognitive Science

Background:

• Humor's role in infant socio-cognitive development is recognized, but longitudinal data is limited.
• Existing research lacks detailed analysis of humor appreciation and production in early childhood.

Purpose of the Study:

• To investigate humor appreciation and production in infants aged 12-36 months.
• To analyze the types of incongruity (Script Opposition) and knowledge domains in infant humor.
• To refine theories on humor development stages in early childhood.

Main Methods:

• Naturalistic observation of mother-child interactions (30 minutes) at 6-month intervals.
• Annotation of 271 humorous episodes based on laughter and incongruity (Script Opposition).
• Classification of Script Oppositions using Hempelmann and Ruch's framework and knowledge domains.

Main Results:

• Distinct distributions of Script Oppositions and knowledge domains were observed between mothers and children.
• Children showed developmental trajectories in Script Oppositions and knowledge domains.
• Infants favored humor with multiple Script Oppositions between 12-30 months, indicating a need for multiple cues.

Conclusions:

• Humor production and perception in infants reflect cognitive, pragmatic, and linguistic development.
• Findings suggest some humor types emerge earlier than previously theorized, refining developmental models.
• This study offers insights into children's knowledge acquisition through humor analysis.
