Desensitization techniques are often used in autism to help individuals become more comfortable with sensory sensitivities and reduce anxiety or aversions to specific stimuli. These techniques involve gradual and controlled exposure to sensory experiences or situations. Here are some desensitization techniques that can be beneficial for individuals with autism:
1. Gradual Exposure:
Gradual exposure involves introducing sensory stimuli or situations in a step-by-step fashion. The goal is to start with a minimal level of exposure that the individual can tolerate and gradually increase it over time. For example, if a child is sensitive to certain textures of food, you might begin by simply touching the food, then progressing to having it on the plate, and eventually tasting a small amount.
2. Systematic Desensitization:
 This technique pairs relaxation strategies with the gradual introduction of a sensory stimulus. The individual learns relaxation techniques (e.g., deep breathing, progressive muscle relaxation) and practices them while being exposed to the sensory stimulus. Over time, the individual becomes less anxious and more comfortable with the stimulus.
3. Modeling:
Modeling involves demonstrating appropriate and relaxed responses to sensory stimuli. It can be particularly effective for children with autism who learn by observing others. For example, if a child is anxious about visiting a new place, a parent or therapist can model calm and relaxed behavior during the visit.
4. Sensory Integration Therapy:
Sensory integration therapy, provided by occupational therapists, uses activities and exercises to help individuals better process and respond to sensory information. It may involve activities like swinging, deep pressure massage, and tactile experiences to help individuals become desensitized to sensory sensitivities.
5. Social Stories:
Social stories can be used to prepare individuals for sensory experiences by describing what to expect and how to react. For example, a social story can explain the sights, sounds, and sensations associated with a visit to a dentist’s office, helping the individual feel more prepared and less anxious.
6. Visual Schedules and Timers:
Timers: Visual schedules and timers can be used to provide structure and predictability in sensory-rich environments. By using visual supports, individuals with autism can anticipate sensory experiences and better prepare themselves.
7. Exposure Therapy:
Exposure therapy involves repeatedly exposing the individual to the sensory stimuli that trigger anxiety or discomfort. Gradually increasing exposure can help individuals become less sensitive or anxious in response to the stimulus. This technique is often used in a controlled and supportive environment.
8. Occupational Therapy:
Occupational therapists can provide a range of desensitization techniques tailored to the individual’s specific sensory sensitivities. These may include activities to improve tolerance for sensory input and decrease sensory aversions.
9. Positive Reinforcement:
Reinforcement: Providing positive reinforcement, such as praise or rewards, for successfully engaging with sensory stimuli can motivate individuals to participate in desensitization activities.
10. Choice and Control:
Allowing individuals to have some control over sensory experiences can help reduce anxiety. For example, letting them choose between different sensory activities or offering breaks when needed can provide a sense of control.
It’s important to work with professionals who have experience in autism and sensory sensitivities when implementing desensitization techniques. The specific techniques used should be tailored to the individual’s needs and preferences, and progress should be monitored carefully to ensure that the desensitization process is effective and well-tolerated.
