  3. Wikipedia Definition Critical thinking involves determining the meaning and significance of what is observed or expressed, or, concerning a given inference or argument, determining whether there is adequate justification to accept the conclusion as true (Wikipedia, 2010).

  4. Critical Thinking • Behavior Analysts are critical thinkers by nature. • Professionals who aren’t in our field may have mixed feelings on our emphasis on data. • It is possible to come across as cynics when given a situation where there’s a “warm and fuzzy” story, but no evidence to support it.

  5. Critical Thinking Fail “My son began aromatherapy treatment on Tuesday and started reading words on Wednesday!” =

  6. Science • Scientists need certain information before making decisions • Experimental control • Observational Reliability • Social Validity

  7. Applied Behavior Analysis • No other treatment comes close to the rigor of ABA • We are more concerned with causal variables surrounding human behavior • General correlational findings hold no weight • “Girls are better at math” – according to what study?

  8. Replicating Research • We believe in a treatment after a certain number of replications have been made. • Even after a study has been published that doesn’t mean its applicable to every learner. • What do we do to establish a functional relationship? • Take baseline, test the intervention • Determine if it works for a learner in that setting • Sometimes we try to replicate a published study and it doesn’t work with our learner. • This is why we take baseline and collect ongoing data.

  9. Casual Versus Critical Thinking • Most of our day to day thinking is not critical thinking, but casual thinking, or problem solving. • What should I eat for breakfast? • What should I wear? • Sometimes it’s better to use casual thinking, especially when interacting with others. • Too much critical thinking may reduce the number of close friends you have. • If someone tells you to try a new pizza place and you ask for data, they may be less likely to tell you about new eateries in the future • There are certain times where critical thinking is essential and can prevent wasted time and/or money.

  10. Critical Thinking in Action • The ABA version of critical thinking comes from single-subject experimental methods. • We have over four decades of research to rely on • This may explain why we are so skeptical about pseudo science, fad treatments, etc. • There is a very large amount of new theories that have not been tested. • Especially for autism – • Chelation therapy, gluten/casein-free diet, etc.

  11. Fad treatments

  12. Sensory Integration Therapy • What types of things are done in SIT? • brushing • deep pressure hugs • massages • rolling on a mat

  13. Sensory Integration Therapy • What is it supposed to do? • Enhance the individual's ability to focus • How can we measure this? • ???

  14. Arguments for SIT Casual • Why not? • It’s been around for a while and I know a lot of OT’s that use it. • Parents are happy with it • The learner “enjoys” it Critical Where are the data supporting the treatment?

  15. Critical vs. Casual • Using SIT or any other treatment without any evidence to support its effectiveness with a client isn’t critical thinking (Refer to Ethics Code for Behavior Analysts). • This can lead to wasted time, money, etc. • These treatments are merely assuming that the procedure is effective and that the theory is correct. • Research behind SIT and other fad treatments are not valid. • A study done by Mason and Iwata (1990) actually showed an increase in self-injurious behavior when SIT was introduced.

  16. What’s next?

  17. Facilitated Communication • Began in Australia as a treatment for individuals with cerebral palsy. • Came to USA in the early 1990s as a method for assisting communication for individuals with autism (Jackson, Foxx, & Mulick, 2005). • Supporters of FC: • Believed individuals with autism have “undisclosed literacy” (Burch and Bailey, 2009) • A “facilitator” can assist them in bringing out their latent literary talents.

  18. QUESTION • Why do parents try fad treatments with no evidence? • What type of thinking are they engaging in? • Critical or casual? • What are possible repercussions of this?

  19. Review Why is it important to engage in critical thinking? When is it ok to use casual thinking instead?

  20. “ What skeptical thinking boils down to is the means to construct, and to understand, a reasoned argument-especially important-to recognize a fallacious or fraudulent argument.” - Carl Sagan
