What is Sandplay Therapy?
1. People (especially children) will engage in play behavior in order to work through
their interior obfuscations and anxieties.
2. According to this particular viewpoint, play therapy can be used as a self-help mechanism, as long as children are allowed time for “free play” or “unstructured play.”
3. An example of a more directive approach to play therapy, for example, can entail the use of a type of desensitization or relearning therapy, to change troubling behaviors, either systematically or through a less structured approach.
4. The hope is that through the language of symbolic play, such desensitization will likely take place, as a natural part of the therapeutic experience, and lead to positive treatment outcomes.
