1. The auditory stream is received and includes an acoustic stimulus perceptually representing an object.

2. In dressing Apraxia and in some types of constructional Apraxia, the defect appears to be perceptually based

3. Augmented reality is used to enhance natural environments or situations and offer perceptually enriched experiences.

4. 11 As for size constancy it is linked with the coordination of perceptually controlled movements.

5. The auditory stream is modified based on the selected parameter, to reduce the predetermined acoustic detail characteristic while preserving a lexicality of the stimulus, such that the reduced acoustic detail characteristic enhances perception of the object by the ASD individual even when the stimulus includes two or more acoustically distinct stimuli each perceptually representing the object.
