This Video dives into the details of Operant Behaviour and Respondent Behaviour concepts in Applied Behaviour Analysis (ABA).
- Operant Behaviour: This refers to behaviours that are influenced by their consequences. Operant behaviours are voluntary actions that an individual takes to obtain a desired outcome or avoid an undesired one. These behaviours are not elicited by specific stimuli but are emitted by the individual.
- Operant Conditioning: This is the process by which operant behaviours are modified through reinforcement or punishment. It involves strengthening or weakening behaviours based on the consequences that follow them. There are four main types of consequences:
- Positive Reinforcement: Adding a pleasant stimulus to increase the likelihood of a behaviour (e.g., giving a child a treat for doing their homework).
- Negative Reinforcement : Removing an unpleasant stimulus to increase the likelihood of a behaviour (e.g., taking painkillers to relieve a headache).
- Positive Punishment: Adding an unpleasant stimulus to decrease the likelihood of a behaviour (e.g., scolding a child for misbehaving).
- Negative Punishment: Removing a pleasant stimulus to decrease the likelihood of a s behaviour (e.g., taking away a toy when a child misbehaves).
- Operant Extinction: This occurs when a previously reinforced behaviour is no longer reinforced, leading to a decrease in the frequency of that behaviour. For example, if a child no longer receives praise for completing their homework, they may gradually stop doing it.
- Respondent Behaviour: Also known as reflective or involuntary behaviour, these are automatic response to specific stimuli. They are not controlled by consequences but are elicited by antecedents condition.
- Classical Conditioning (Pavlovian Conditioning): This is a learning process where a neutral stimulus becomes associated with an unconditioned stimulus, resulting in a conditioned response. It was first described by Ivan Pavlov in his experiments with dogs. Key concepts include:
- Unconditioned Stimulus (US): A stimulus that naturally elicits a response (e.g., food causing salivation).
- Unconditioned Response (UR): A natural response to the unconditioned stimulus (e.g., salivation in response to food).
- Conditioned Stimulus (CS): A previously neutral stimulus that after being paired with the conditioned stimulus, elicits a conditioned response (e.g., a bell that is rung before feeding).
- Conditioned Response (CR): The learned response to the conditioned stimulus (e.g., salivation in response to the bell).
- Respondent Extinction : This occurs when the conditioned stimulus (CS) is repeatedly presented without the unconditioned stimulus (US), leading to a decreaded in the conditioned response (CR). For example, if the bell is rung without presenting food, the dog will eventually stop salivating in response to the bell.
These concepts are fundamental in understanding how behaviour are learned and modified. They are crucial for designing effective interventions in various fields, including therapy, education, and behaviour management.
