  tried out PECS to help children with ASD improve speech

  the 3 children in the study had a hard time speaking and already tried other programmes
• The children used PECS for 2 15 min sessions each week
• After using PECS children started to speak more on their own
• One child went from speaking 28% of the time to speaking all the time without being prompted
• The improvements didnt disappear over time,even a year later,they were still doing well
• Children made better eye-contact,paying attention to others and had fewer trantrums
• Shows PECS is effective and quick and easy
• Skills learnt can be handy in all situations
• Study only had 3 children,cant be sure all children would be as effective
