ABSTRACT
Theory of Mind is a metacognitive skill that, in many cases, is deficient in autism. In this paper, we present a clinical study conducted with a child diagnosed with autism, which verifies the effectiveness of a training protocol testing false beliefs, which has been considered to measure the Theory of Mind. Basically, the protocol incorporates a number of verbal prompts (such as emphasizing the elements of the narratives that indicate situational or temporary changes), trains many examples, extending the tests incorporating some games with more familiar objects from the child's daily life, applies differential contingencies to discriminate right from wrong in each child's responses and provides descriptive feedback. The results show that the training protocol achieved the highest level of correct trials and the child generalizes the ability to take the perspective of her natural context.
