ASD - Methods of Modifying Flashcards
1 What is PECS?
Replaces spoken words with pictures. Although most users of PECS recommend the use of verbal speech as well this comes as secondary to the use f pictures.
1 What does PECS use?
Behaviourist concepts such as operant conditioning and modelling to improve communication and other social behaviour
1 What are the 7 stages of PECS?
- Pre-programe preparation - find objects that the child is interested in
- Physical exchange - teacher will show one of the objects where the facilitator will encourage the learner to pick up the picture card and hand it to the teacher
- Increasing independence - physcial distance between learner and teacher is increased so more effort is required
- Learning to discriminate - given a picture book where they have to find what they want between similar objects
- ** Sentence structure** - encouraged to form ‘sentence strips’ to ask for an object
- **Answering direct questions **- Use of sentence should be automatic and when asked a direct question should aswer with a full sentence strip
- Commenting - learner will be asked questions where they can comment more widely on their experiences
1 Why is there limited support for PECS? (communication)
Flippin (2010) - In some cases, speech development was actually negatively effected. Research was also flawed in terms of methodology - rated quality as ‘adequate’
1 Supporting research (spontaneous speech) for PECS?
Charlop-Christy (2002) - Children used substantially more spontaneous speech after PECS when compared with before
One child improved 28% to 100% which wass shown 12 months later in a follow uo
Eye contact and joint attention was also improved
1 Ease of use for PECS?
Charlop-Christy (2002) - PECS can be conducted very quick and easily. The mean time for ll 6 six stages is 170 minutes
1 Why does PECS have limited use?
Ganz (2012) - PECS may be most effective fro younger learners however the use of this system fro older hcildren/adults may be less effective so may not be appropriate for all with ASD
1 Ethical benefits of PECS?
Identification of reinforcers means that the child is likely to enjoy the training process - receive positive reinforcement
Low risk of psychological harm
1 How is PECS successful?
Imbedded operant conditioning is likely to be successful and may bring improvements in communication quickly for the child
Likely to lead to improved self-esteem - less likely to experience the communication failures they may be used to
1 What are the ethical issues of PECS Baron-Cohen adressed?
Relies on external rewards - risk of harm during stage 1
removes freedom from the child
Use of internal reward should be used (pre-existing interest) instead of an external reward which can be withheld
1 Financial costs of PECS?
Pyramid Educational Consultants - insists practitioners are trained by them. Costs are usually met by the public sector
Inconsistent evidence for effectiveness of PECS over costs of programmes
Alternative treatments - could be more expensive and may be less effective. Research - PECS may be worth the costs incurred
1 Economic benefits of PECS?
improvements of communication skills may gain greater independence - more able to work and contribute to society and economy more effectively
2 What is RDI?
What does RDI focus on?
CBT - trying to improve the cognitive and empathy deficits through modifying the child’s perception of other peoples thoughts and feelings
2 Six objectives of RDI?
- Emotional referencing - learn from emotional experiences of others
- Social coordination - observe and control behaviour to paricipate in social relationships
- Declarative language - use language and non-verbal communication to express curiosity
- Flexible thinking - adapt and alter plans as circumstances change
- Relational information processing - put things into context and solve problems that lack clear solutions
- Foresight & Hindsight + Anticipate future possibilities based on past experiences
2 What is it based on?
Gustein?
The assumption that children with ASD have missed important developmental skills:
- Beginning a conversation
- Sharing a joke
- Sharing feelings with others
Gustein’s (2009) concept of dynamic intelligence which Gustein argues can be developed in those with ASD
