    Summary

    Withdrawing food or attention during meals significantly reduced self-injurious behavior in profoundly retarded girls. Preventing eating was most effective, suggesting reinforcement plays a key role.

    Area of Science:

    • Behavioral Psychology
    • Developmental Disabilities
    • Applied Behavior Analysis

    Background:

    • Self-injurious behavior (SIB) is a significant challenge in individuals with profound intellectual disabilities.
    • Understanding the function of SIB, particularly during specific routines like mealtimes, is crucial for effective intervention.

    Purpose of the Study:

    • To investigate the impact of withdrawing food, attention, or both on the rate of SIB during mealtimes.
    • To determine the effectiveness of contingent interruption of meal consumption in reducing SIB.

    Main Methods:

    • The study involved three profoundly retarded girls exhibiting self-injurious behavior during mealtimes.
    • Experimental conditions included withdrawal of food, withdrawal of attention, and simultaneous withdrawal of both.

    Main Results:

    • Treatments that prevented eating (food withdrawal, or food and attention withdrawal) led to a marked reduction in SIB.
    • Withdrawal of attention alone, allowing eating to continue, increased SIB in two subjects and had minimal effect on the third.

    Conclusions:

    • Contingent interruption of meal consumption is an effective strategy for reducing self-injurious behavior.
    • The rate of SIB appears to be influenced by reinforcement contingencies, highlighting the importance of analyzing behavioral function.
