Fractionation

Question 1

Happe et al 2006

Answer 1

There is no single cognitive, genetic or brain region account for all the symptoms presented in Autism, therefore we should look at each aspect individually into order to gain abetter understanding. Twin studies only show moderate correlations between social and non-social. Those with impairment in only 1 oe 2 may be let down by needing 3 for diagnosis.

Question 2

Murray et al 2004

Answer 2

looked into how related ASD symptoms are found that many studies only use clinical ASD samples, which leads to range restriction of symptoms. therefore some studies may have under estimated how inter-correlated the ASD symptoms are.

Question 3

Mandy et al 2012

Answer 3

Using a 1,2 & 3 factor model to best describe Autism found that a 2 factor model in-line with DSM-5 was best used to explain the symptoms, therefore offering an alternative to the triad.
