Sensory reinforcement: effects of response-contingent vestibular stimulation on multiply handicapped children
Insights
Vestibular stimulation was found to be reinforcing for children with severe disabilities. For most, it was the preferred reinforcer over food, praise, and other sensory inputs.
Area of Science:
- Neuroscience
- Developmental Psychology
- Special Education
Background:
- Vestibular stimulation is crucial for sensory processing and development.
- Children with severe disabilities, particularly those who are nonambulatory, may experience movement deprivation.
- Understanding preferred sensory reinforcers is key for effective intervention.
Purpose of the Study:
- To investigate the reinforcing properties of vestibular stimulation.
- To determine the relative preference for vestibular stimulation compared to other sensory inputs (food, praise, visual, auditory).
- To explore implications for programming for multiply handicapped children.
Main Methods:
- Five multiply handicapped, severely retarded young children participated.
- Children were trained to use a pressure-sensitive adaptive switch.
- Access to different reinforcers, including vestibular stimulation, was contingent on switch activation.
Main Results:
- Vestibular stimulation was a reinforcing stimulus for all participating children.
- Four out of five children showed a preference for vestibular stimulation over other tested reinforcers.
- The findings highlight the potential of vestibular input as a primary reinforcer.
Conclusions:
- Vestibular stimulation can be a powerful and preferred reinforcer for severely disabled children.
- These findings have implications for designing interventions that address sensory needs and movement deprivation.
- Tailoring sensory programming can enhance engagement and learning in this population.
Abstract:
The reinforcing properties of vestibular stimulation were investigated, including the relative preference for vestibular stimulation and food, praise, visual, and auditory stimulation. Five multiply handicapped, severely retarded young children were trained to operate a pressure-sensitive adaptive switch to gain access to a given reinforcer during successive intervention phases. The results suggest that vestibular stimulation was reinforcing to all subjects. Vestibular stimulation appeared to be the preferred reinforcer for 4 of the 5 children. Results were discussed relative to the movement deprivation experienced by nonambulatory children. Possible implications for programming efforts were described.
