2-3: Behaviourist Psychology Flashcards
What does the behaviourist perspective focus on?
Focuses on observable behaviour as a means to studying the human psyche.
What is the primary tenet of behaviourism?
Psychology should concern itself with the observable behaviour of people and animals, not with unobservable events that take place in their minds.
Who were the main influences on behaviourism?
- Ivan Pavlov
- Edward Lee Thorndike
- John B. Watson
- B.F. Skinner
Define
Classical Conditioning
As we learn, we alter the way we perceive our environment, the way we interpret the incoming stimuli, and therefore the way we interact, or behave.
The smell of a cologne, the sound of a certain song, or the occurrence of a specific day of the year can trigger distinct memories, emotions, and associations.
When we make these types of associations, we are experiencing classical conditioning.
What was Ivan Pavlov’s main contribution to behaviourism?
Pavlov founded classical conditioning.
How did Pavlov discover classical conditioning?
Pavlov actually discovered classical conditioning accidentally while doing research on the digestive patterns in dogs.
Define
Operant Conditioning
A method of learning that uses rewards and punishment to modify behavior.
Which is the most powerful type of operant conditioning?
Positive reinforcement
What are the types of operant conditioning?
Reinforcement (increase behaviour), and punishment (decrease behaviour)
Define
Positive reinforcement
Positive reinforcement involves adding a pleasant or rewarding stimulus to increase the likelihood of a behavior occurring again in the future. When a behavior is followed by a positive reinforcer, the individual is more likely to repeat that behavior. For example, giving a child a piece of candy (pleasant stimulus) for completing their homework (desired behavior) is an example of positive reinforcement.
Define
Negative reinforcement
Negative reinforcement involves the removal or avoidance of an aversive or unpleasant stimulus to increase the likelihood of a behavior occurring again. When a behavior leads to the removal of something undesirable, the individual is more likely to engage in that behavior in the future. For instance, a person might wear a seatbelt (behavior) to stop the annoying sound of a car’s seatbelt reminder (aversive stimulus).
Define
Positive punishment
Positive punishment involves adding an aversive or unpleasant stimulus following a behavior to decrease the likelihood of that behavior occurring in the future. An example is scolding a child (aversive stimulus) for misbehaving (undesired behavior).
Define
Negative punishment
Negative punishment involves removing a pleasant or desired stimulus following a behavior to decrease the likelihood of that behavior happening again. For instance, taking away a teenager’s phone (desired stimulus) as a consequence for breaking curfew (undesired behavior) is an example of negative punishment.
Define
Escape
In relation to negative reinforcement
Escape is a type of negative reinforcement that occurs when an individual engages in a behavior to terminate or escape from an ongoing aversive stimulus. In other words, the person is trying to “get away from” or “end” something unpleasant. The behavior serves as a means of immediately reducing or eliminating the aversive stimulus. An example of escape behavior is covering your ears (behavior) to escape from a loud and irritating noise (aversive stimulus).
Define
Active avoidance
In relation to negative reinforcement
Active avoidance is a type of negative reinforcement that involves the individual engaging in a behavior to prevent or avoid the onset of an aversive stimulus altogether. Unlike escape, where the aversive stimulus is already present, active avoidance aims to ensure that the aversive stimulus does not occur in the first place. This behavior is proactive and is reinforced by the absence of the aversive stimulus. For instance, taking an umbrella (behavior) with you on a cloudy day to avoid getting wet from the rain (aversive stimulus) is an example of active avoidance.
