Generalized instruction following with pictorial prompts

Area of Science:

• Behavioral Psychology
• Developmental Disabilities Research
• Applied Behavior Analysis

Background:

• Pictorial prompts are used to enhance maintenance and generalization of skills.
• Previous research shows pictorial prompts are effective, but the precise mechanism of stimulus control is not fully understood.
• Understanding stimulus control is crucial for optimizing the benefits of pictorial prompts.

Purpose of the Study:

• To explicitly examine the stimulus control exerted by pictorial prompts.
• To investigate whether establishing stimulus control facilitates generalized pictorial instruction following.
• To determine if training task sequences is sufficient for generalized learning.

Main Methods:

• Three 4-year-old children with developmental disabilities participated.
• Participants were taught to complete instructional sets using pictorial prompts designed to control responding.
• Generalization was assessed after training with a subset of the instructional sets.

Main Results:

• All participants demonstrated generalization to a new instructional set after training on three sets.
• The study suggests that training a single task sequence may not be enough for generalized pictorial instruction following.
• Establishing stimulus control by pictorial prompts appeared to facilitate the acquisition of a generalized repertoire.

Conclusions:

• The degree of stimulus control by pictorial prompts influences their effectiveness in maintenance and generalization.
• Focusing on stimulus control by prompts, rather than solely on behavioral chains, may be a more effective strategy for promoting generalized learning in children with developmental disabilities.
• Further research can explore optimizing pictorial prompt design for maximum stimulus control and generalization.
