Imitation in EMR boys: model competency and age

Area of Science:

• Behavioral Psychology
• Developmental Psychology
• Special Education

Background:

• Imitation is a key learning mechanism.
• Understanding factors influencing imitation in children with intellectual disabilities is crucial for effective instruction.
• Previous research has explored model characteristics, but less is known about their impact on EMR boys' imitation of both task-related and social behaviors.

Purpose of the Study:

• To investigate how model age (adult vs. peer) and competence (high vs. low) affect the imitation of motor skills and social behaviors in Educable Mentally Retarded (EMR) boys.
• To determine which model characteristics are most influential in promoting imitation in this population.
• To inform the development of more effective instructional strategies using modeling.

Main Methods:

• Eighty EMR boys participated in the study.
• Participants watched videotapes of models (adult or peer) performing a motor task with varying competence levels.
• Models also displayed distinct off-task social behaviors.

Main Results:

• EMR boys imitated off-task social behaviors more from high-competent and peer models compared to low-competent and adult models.
• High-competent models were imitated more than low-competent models for the motor-skill task.
• No significant effect of model age was found on imitation of the motor task.

Conclusions:

• Competent models, particularly peers, are more effective in influencing imitation behaviors in EMR boys.
• Instructional strategies should prioritize using competent peer models who demonstrate adaptive behaviors.
• The findings support the use of modeling, especially with carefully selected models, as a viable instructional approach for EMR boys.
