Babies develop private gestures, using them as "tools of thought" for self-communication before language acquisition. These private signs help infants solve problems and think through actions independently.

Area of Science:

  • Developmental Psychology
  • Cognitive Science
  • Linguistics

Background:

  • Infants understand and use gestures communicatively.
  • A gap exists in understanding private gestures and their role in cognitive development.
  • Private gestures are communicative acts directed towards oneself.

Purpose of the Study:

  • To investigate the emergence and function of private gestures in pre-linguistic infants.
  • To analyze private ostensive and pointing gestures as self-reflexive tools.
  • To explore how private gestures facilitate problem-solving in early development.

Main Methods:

  • A longitudinal case study of one child aged 12-18 months.
  • Observation and analysis of gestural communication, focusing on private instances.

Related Experiment Videos

  • Detailed examination of object use and problem-solving scenarios.

    • Main Results:

    • Identified two types of private gestures: ostensive and pointing.
    • Observed these gestures used with a self-reflexive function by the infant.
    • Demonstrated private gestures aiding in "thinking" to solve object-use problems.

    Conclusions:

    • Private gestures serve as early "tools of thought" before language.
    • Self-directed gestures play a crucial role in infant problem-solving and cognitive development.
    • Private gestures are a precursor to symbolic representation and self-regulation.
