The Behaviourist Approach to Personality Development
Respondent Behaviour
•Refers to a specific response to a known stimulus
–e.g. Shivering when it is cold
•Although these responses are spontaneous and automatic,at a higher level, respondent behaviour may also be learned
•Pavlov explored how respondent behaviour could be conditioned
Classical Conditioning
•Skinner applied this phenomenon to personality development
Learning theory is rooted in the work of
Ivan Pavlov
Ivan Pavlov
•Classical Conditioning Theory
–Based on physical reflexes that are already present in an organism which become associated with repeated neutral events
Classical Conditioning
•Deals with what happens before the behaviour (i.e. the response) and usually includes physiological reflexes like sweating, blinking, or salivating
Operant Conditioning
•Learning is based on the consequences of the behaviour
–Being praised for cleaning your room, will most likely do it again
•Behaviour has been reinforced
Classical Conditioning in Pavlov’s dogs
Classical conditioning can therefore be defined as a type a stimulus(S) that acquires the capacity of learning to evoke a reflexive response(R)
–In Pavlov’s experiment, the food is a stimulus, which evokes the natural reflexive response of the dog salivating
•In this situation, because salivating when food is present is a natural reaction (or reflex), we say that both the stimulus and response are unconditioned
neutral stimulus
This stimulus (that is not initially related to the unconditioned stimulus)
Factors affecting conditioning
–Contiguity
–Extinction and Spontaneous Recovery
–Generalisation
–Discrimination
Contiguity
Extinction
–Pavlov discovered that there is a gradual weakening and eventual disappearance of the conditioned response tendency in the absence of the unconditioned stimulus
Extinction and Spontaneous Recovery
•In essence, if the person or animal continues to have the conditioned stimulus presented but without the unconditioned stimulus, the conditioned stimulus loses its power to evoke the conditioned response
–e.g. After a certain period of time, Pavlov’s dogs stopped salivating when only the bell (the conditioned stimulus) was rung without any food (unconditioned stimulus) being brought to them
Spontaneous recovery
–At times, however, the conditioned response can reappear some time after the period of extinction
•It can occur after a period of non-exposure to the conditioned stimulus
–However, it is generally not as strong or carried out to the same degree as with the initial conditioning process
Generalisation
•In his experiments, Pavlov found that sometimes, there is a tendency for a new unconditioned stimulus(similar to the original stimulus) to elicit a response that is similar to the conditioned response
–This is known as generalisation
•e.g. Little Albert
•This aspect of classical conditioning helps make human behaviour highly adaptable
Little Albert
Discrimination
•In contrast to generalisation, stimulus discrimination occurs when one is conditioned to respond to one stimulus and not another
–This refers to being conditioned to have a specific response to specific stimuli only
•For example, children may initially respond by obeying the commands or requests of all adults (or people socially considered to be authority figures), but over time, they can learn to respond only to their parents
Higher-Order Conditioning
•Higher-order conditioning occurs when a well-learned conditioned stimulus is used to generate a response to another neutral stimulus
higher-order conditioning in Pavlov’s experiment
Some examples of classical conditioning
–Phobias
–Food aversions
–Advertising
Phobias
•When one has an irrational fear of an object, event, or situation, which warrants no logical fear, then one may be said to have a phobia of this stimulus
–This is known as a conditioned emotional response
•A basic classical conditioning model that could generate a phobia is similar to the example of Watson and Little Albert
•Note that the unconditioned response with regard to phobias is always a fear response to the unconditioned stimulus, which is something that does not usually reflexively generate fear
•Neutral stimuli often associated with phobias include heights, insects, animals, etc.
•It can be the association of the neutral stimulus with the unconditioned stimulus once or a repeated number of times
types of phobias and treatment
•Once–If particularly traumatic
•e.g. Seeing someone fall off a cliff
•Repeatedly –Generates a conditioned phobic response of fear to the conditioned stimulus
•The previously neutral stimulus that becomes the phobia–In this case, a fear of heights
•Research suggests that some phobias can be more easily conditionedthan others
–Based on the notion of preparedness
•This idea suggests that, as an evolutionary benefit for survival, we are biologically programmed to learn to fear objects or events that have inherent danger for us
–Even those that can indeed be life threatening under certain circumstances
•The fear is pathological, however, when one is faced with these stimuli in non-threatening situations and one’s phobic reaction may lead to life-impairing strategies in order to avoid having to deal with the stimulus
–e.g. Fearing drowning in a fast-flowing river and thus not taking a shower or a having bath in shallow water
•A psychotherapist may address this issue by encouraging the patient to undergo exposure therapy
–This is a form of cognitive-behavioural therapy in which a patient is prepared for exposure to the stimuli that elicit phobic responses, in order to weaken their strength
•Done through relaxation and cognitive techniques
Food Aversions
•Foods that make us sick may lead to avoidanceof that food, perhaps for a lifetime
–This is because we can develop a conditioned response of feeling physically ill in response to the conditioned stimulus of the food that made us sick
•e.g. Getting food poisoning after eating sushi
–This may result in severe vomiting, nausea, diarrhoea ,and a fever as our bodies attempt to process the tainted food
»Results in saying, ‘Oh no, I will NEVER have sushi again. The last time I had it, I was sick for days. Now, I feel ill even at the thought of raw fish.’
