Behaviourist Approach Flashcards
John B Watson, remind me of Wallace, from Wallace and Gromit and gromit, you have the dog (pavlovs dog) and they love cheese (like skinners rats)
What is the Behaviourist approach?
It is a way of explaining behaviour in terms of
what is observable in terms of learning.
What is Classical conditioning?
It is learning through association when two stimuli are repeatedly paired together. (Ring bell, get food)
What is Operant conditioning?
It is a form of learning in which behaviour is shaped and maintained by its consequences.
What is Reinforcement?
It is a consequence of behaviour that increases the likelihood of that behaviour being repeated,
can be positive or negative.
What are the strengths of the behaviourist approach
Gave psychology scientific
credibility. (Observable and measurable)
Used in real-life settings. (token economy)
What are the weaknesses of the behaviourist approach
Portrays humans as acting like
machines. (humans
are seen to be passive with no
conscious thought)
Based heavily on animal research, which has ethical and practical issues. (The animals involved in Skinner’s box experiments were exposed to stressful and aversive conditions and thus may have had an impact on their behaviour.)
What method is used for the behaviourist approach
Lab experiments
What is Neutral Stimulus (NS)?
It is things in the environment for which we have no natural reflex response – don’t usually affect behaviour. (a random bell ringing)
What is Unconditioned stimulus (UCS)?
It is an environmental stimulus that naturally causes a reflex response in humans. (Food causes natural reflex responses in humans and dogs)
What is Unconditioned response (UCR)?
It is an automatic and unlearned reflex response to an unconditioned stimulus. (Like when animals salivate at food)
What is a Conditioned stimulus (CS)?
If a Neutral Stimulus is paired with an Unconditioned Stimulus repeatedly, the two stimuli become associated until the neutral stimulus causes the same response as the UCS. When it does it becomes a conditioned stimulus.
(If a bell (NS) repeatedly and consistently paired with food (UCS). Eventually the bell alone (now a CS) causes a hunger response, salivation.)
What is a Conditioned response (CR)?
We show the same response to the NS without the UCS being present – they have learned to respond. (If, every time a dog hears a bell (CS) they salivate (CR) – this is a conditioned response.)
What is Positive reinforcement?
It is receiving a reward when behaviour is performed (e.g. praise from a teacher)
What is Negative reinforcement?
It is when an person produces behaviour that avoids something unpleasant (e.g. handing in an essay to avoid teacher telling you off)
What is a Punishment?
It is an unpleasant consequence of behaviour, for example being shouted at by a teacher for talking when they are. (Finding a way to avoid that would be negative reinforcement).
