Language Development

440
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Area of Science:

  • Developmental Psychology
  • Linguistic Development
  • Child Development

Background:

  • Gesture development is a crucial precursor to language acquisition.
  • Understanding ethnic and contextual variations in gesture use is vital for accurate developmental assessments.
  • Previous research has not fully explored these variations in diverse populations.

Purpose of the Study:

  • To examine gesture frequency in Hispanic and non-Hispanic White prelinguistic children (9-15 months).
  • To investigate the relationship between gesture use and developmental abilities.
  • To explore how setting (semi-structured vs. structured) influences gesture frequency.

Main Methods:

  • Data collected via parent questionnaires, Mullen Scales of Early Learning (MSEL), and video recordings.
  • Video samples coded for total frequency, behavior regulation, social interaction, and joint attention gestures.
  • Analysis controlled for ethnicity, gender, and age.

Main Results:

  • Children used fewer gestures in semi-structured settings compared to structured settings.
  • Non-Hispanic White children used more behavior regulation and joint attention gestures, but fewer social interaction gestures.
  • Total gesture frequency, behavior regulation, and social interaction gestures predicted developmental abilities, independent of ethnicity, gender, and age.

Conclusions:

  • Gesture use patterns differ between ethnic groups and settings.
  • Gesture frequency is a significant predictor of developmental abilities in prelinguistic children.
  • Findings have implications for early identification of developmental delays and understanding gesture-language integration.
