P3(i) Pupils begin to communicate intentionally. They seek attention through eye contact, gesture or action. They request events or activities, for example, pushing another person's hand towards a switch. They participate in shared activities with less support. They sustain concentration for short periods. They explore materials in increasingly complex ways, for example, moving in and out of a sound beam to create different effects. They observe the results of their own actions with interest, for example, feeling the changing vibrations as they switch a massage table on and off. They remember learned responses over more extended periods, for example, returning to a favourite item of equipment in the multi-sensory environment from session to session.
