Applied behaviour analysis (ABA) is a systematic way
of observing an individual’s behaviour, identifying desirable changes in it and
then using appropriate methods to infer a positive change in the original
behaviour. The field of ABA has shown a more significant growth in the area of
behavioural intervention for children with autism spectrum disorder, as shown
by the growing number of care providers and certified professionals in this
field (Cooper, Heron & Heward, 2007). My future career plans involve
working with autistic children in an educational setting; for instance in a
special needs school or in private care, of which ABA is quickly becoming the
most appropriate method of teaching.
This approach is primarily based on theories of
operant conditioning, and can be easily applied to scenarios of therapist and
child interactions. For example, the therapist may try to improve a child’s
communication and social skills by demonstrating more effective ways of
interacting with others, and then rewarding the child upon independent
demonstration of this. The therapist can then analyse how well the approach has
worked, and if necessary, make any changes to support the positive behaviour
change and influence it in the right direction.
There is substantial evidence to support that ABA is
beneficial to the intellectual, verbal and social development and functioning
of children with autism spectrum disorders (Foxx, 2008; Remington et al., 2007)
and positive results have been reported for daily living skills, academic
performance and communication skills (Eikeseth, Smith, Jahr, & Eldevik,
2007; Remington et al., 2007).
A cross-cultural meta analysis conducted by
Virues-Ortega (2010) supported this by concluding 18 studies to produce a
positive effect for 323 children (mean age range = 22.6m – 66.3m) receiving
intervention from 48 – 407 weeks and 12 – 45 weekly hours respectively. The
pooled effect size of this meta analysis was 1.19 (95% Cl 0.91 to 1.47, p <
0.001) – the table below shows the breakdown for effect size for communication,
daily living skills, socialization and adaptive behaviour composite scores of
ABA intervention.
ABA has a significant upon the functioning of social
interactions in autistic children, and this can simply be described as the
influence of positive and negative reinforcement in the operant conditioning
technique of behaviour influence. It is particularly beneficial from the
individuality point of view, where ABA application is catered to each child’s
specific needs.
