How Behavioral Treatments Are Based On Basic Principles And Research

Good Essays

Self-injurious behaviour (SIB) is a debilitating problem that affects individuals with developmental delays (Singh, Dawson, & Gregory, 1980). SIB entails a range of chronic behaviours which lead to physical harm that occur frequently within a sustained period, e.g., include self-biting, self-hitting, and self-pinching (Favell et al., 1982). The adverse impact of SIB escalates as these individuals approach adulthood, with increasingly prevalent problems such as physical damage, social seclusion, and limited academic and work opportunities (Kurtz et al., 2003). To date, research has demonstrated that behaviour analytic treatments are substantially successful (Matson & LoVullo, 2008). This essay aims to discuss how behavioural treatments are …show more content…

Researchers thereafter developed interventions that were heavily influenced by the operant learning theory (Matson, Benavidez, Compton, Paclawskyj, & Baglio, 1996). Proponents suggest that the probability of a behaviour occurring in the future is dependent on its consequence (Bachman, 1972). As such, modifying such behaviour involves changing the consequence (i.e., reinforcement, punishment). Reinforcement is a consequence that follows a behaviour and increases the probability of said behaviour occurring in the future (Cooper, Heron, & Heward, 2014). Positive reinforcement involves presenting a desirable stimulus while negative reinforcement involves removing an aversive stimulus. For example, desirable behaviours are positively reinforced with tangibles or negatively reinforced by the termination of demands. Punishment on the other hand is a consequence that follows a behaviour and decreases the future probability of the behaviour occurring (Cooper et al., 2014). Positive punishment involves the presentation of an aversive stimulus while negative punishment is the removal of a desired stimulus. For example, reprimanding the client is a form of positive punishment while ignoring his/her is a form of negative punishment. Although consequence interventions have been considerably successful (Bachman, 1972; Johnson & Baumeister, 1978), inconsistencies in effectiveness were noted (Iwata, Dorsey, Suifer, Bauman, & Richman, 1994).
