Applied Behaviour Analysis
is based on the behavioural approach adopted by Skinner (e.g., 1938, 1953). It focuses
on how environmental events influence behaviour by investigating functional relationships.
This is achieved using the ABC model involving antecedents (events occurring
before behaviour) and consequences (events occurring after behaviour) in order
to understand a person’s learning history and subsequently solve problematic behaviour.
Environmental behaviour
analysts believe intervention strategies should be directly applied to
behaviour regarding the environment. The majority of interventions such as
these are based on the ABC model. The process would begin with defining a
specific and observable target behaviour that is to be altered, for example the
amount of heating a household uses. In order to create a hypothesis, the
functional relationship between the antecedents and consequences surrounding
the problematic behaviour are evaluated. This enables an understanding of
triggers and reinforcements. In the household heating example, the trigger
would be feeling cold prior to turning on or increasing the heating and the
consequence would be subsequently feeling warmer.
Through a process of
observation and recording of behaviour, the baseline rate is obtained. This can
be achieved using continuous recording (recording each occurrence of the target
behaviour in a time period) or interval recording (recording each occurrence of
the target behaviour in a series of short intervals in a time period).
Next, an intervention is
identified that could effectively alter the problematic behaviour so that it is
more desirable i.e. increasing environmentally positive behaviours and
decreasing environmentally negative behaviours. With regards to environmental preservation,
Geller (2010) identified various antecedent interventions: education, messages,
demonstrations, goal setting and engineering and design strategies. So, the household
owners wishing to reduce their heating usage could receive educational
provision informing them of alternative methods of keeping warm and ways to
make heating more effective such as insulating the house. Geller (2010) also
identified factors concerning consequence strategies were also outlined: consequences
should be contingent with the target behaviour, overt behaviours should be targeted
and positive reinforcement consequences may be more beneficial. An example of an
outcome-contingent consequence that effectively increased the frequency of environment-protective
behaviour was receiving two dollars per week for reducing heating 5-10%, with
this increasing to five dollars per week for a reduction greater than 20%
(Winett & Niezel, 1975). In this way, an effective consequence strategy could
be saving money on reducing the amount of heating used.
Comparison of the target
behaviour baseline and the rate after the intervention indicates whether or not
the method adopted was successful. A
simple or cumulative frequency graph makes this task easier as measurements can
be viewed more clearly. If the problematic behaviour has been influenced in a
desirable way then the intervention is deemed to be effective. For example, a
reduction in heating costs would indicate less heating used and would show that
the intervention adopted was successful.
