Chapter 6: Behaviourist and Learning Aspects of Personality Flashcards
What is:
classical conditioning
6.1.1 Conditioning a Response to a Stimulus
Discovered by Ivan Pavlov, who paired food (unconditioned stimulus), which causes salivation in dogs (unconditioned response), with a bell (neutral stimulus). After the food and bell were presented together a number of times, eventually just the sound of the bell elicited salivation, i.e. the conditioned stimulus produced a conditioned response.
What are generalization and discrimination?
6.1.1 Conditioning a Response to a Stimulus
-
generalization: A conditioned response will occur in response to stimuli that are similar to the conditioned stimulus.
- e.g. If a young boy who is stung by bees and bitten by mosquitoes might become fearful of the buzzing of all insects.
-
discrimination: The conditioned response will not occur for all possible similar stimuli, indicating that an animal can learn to tell the difference between different stimuli.
- e.g. If food followed a bell of only one tone and didn’t follow the bell of another, the dog would discriminate this one tone, and the conditioned response would only happen for that particular tone.
How is an explanation of personality using classical conditioning different from that of a biological, psychoanalytic, or neoanalytic explanation? Use the example of phobias.
6.1.2 Behavioural Patterns as a Result of Conditioning
Using the conditioning explanation of someone who has a phobia of snakes, we would conjecture that the individual was taken to the zoo by her grandma when she was 5, and the grandma exhibited a great deal of anxiety in the child’s presence when they approached the snakes. Since the grandma is only acting fearful around the snakes, the child would discriminate this stimulus and learn to be fearful. The child may develop a “personality” that fears situations involving snakes or other reptiles.
This explanation of a phobia is different from a biological explanation that relies on an evolved innate fear of snakes, a psychoanalytic explanation that sees snakes as symbolic of a threatening penis, or a neoanalytic explanation in which fear of snakes is part of our collective unconscious.
What is:
extinction
6.1.3 Extinction Processes
When the conditioned response becomes less frequent over time until it disappears, because the association between the conditioned and unconditioned stimulus stops. In other words, “personality” (pattern of response) changes.
- e.g. If a rape victim who is fearful of going to parties or malls can repeatedly experience these events in the calm presence of a supportive friend, she will be able to undergo a positive personality change.
- However, most of the time people who have a fear of certain things will avoid them, thus not allowing the fear to disappear.
How can behaviourism explain complex personality dimensions, such as neuroticism?
6.1.4 Conditioning of Neurotic Behaviour
Neuroticism may be a conditioned response fostered by an environment that requires the individual to discriminate between events under conditions in which that judgement is almost impossible.
- e.g. Some children find it impossible to predict the reactions of their unstable parents. If they’re never sure whether to expect praise or punishment, they may feel frustrated, anxious, and depressed.
- Pavlov discovered this when he presented food with a circle, but not with an ellipse to a dog, which caused discrimination. Pavloc then increased the roundness of the ellipse until it approximated the circle so that the dog could no longer discriminate, at which point the dog began showing neurotic behaviours.
Why is classical conditioning not as simple as Pavlov had imagined?
6.1.5 Complexities in Application of Conditioning Principles
- Certain organisms respond differently to certain stimuli. For example, dogs can be made to salivate with food, but humans rely more heavily on visual stimuli.
- Much of our learned patterns of responses comes by experiencing or anticipating the consequences (effects) of our actions.
Why did John B. Watson reject introspectionism and psychoanalysis?
6.2.1 The Rejection of Introspection
Watson wanted to develop a rigorous science that didn’t rely on thoughts and feelings elicited through introspection, as these are unobservable and unscientific. Accordingly, he also rejected psychoanalysis, which looked at the unconscious. He much preferred behaviourism and working with animals, which he could observe.
What is:
systematic desensitization
6.2.2 Conditioned Fear and Systematic Desensitization
Watson and Rayner demonstrated how you could become desensitized to your phobias with a little boy named Peter. Peter was afraid of furry things such as rabbits. In several experiments, Peter played with other children in the presence of a rabbit. Gradually, the rabbit was moved closer and closer to Peter while keeping him happy, until he became desensitized ot the rabbit.
- This technique is now commonly used as a phobia treatment in therapy.
- VR technology has been especially useful at reducing costs, but also because people are more willing to do it if they know they won’t have to actually face their fear.
What are the two underlying assumptions that Watson made about behaviourism?
6.2.2 Conditioned Fear and Systematic Desensitization
- That the cause of the problem is irrelevant, and the behaviour itself is the issue. Merely apply the training tools to change the behaviour, and the problem will be solved.
- That the environment is key to understanding a person. Accordingly, if children are raised in a particular environment, they will grow up to be exactly what you want them to be because their personalities are a function of the environment.
What did B.F. Skinner set out to accomplish with his ideas?
6.3 The Radical Behaviourism of B.F. Skinner
Skinner was motivated by the ideas of people like Pavlov, Watson, and Thorndike, who argued that the consequences (effect) of a behaviour will either strengthen or weaken it. Skinner concluded that environment controls behaviour; environmental elements, particularly the consequences of behaviour, are responsible for most behaviour. As such, one must uncover the environmental conditions surrounding any behaviour in order to understand it. He endeavoured to explain behaviour without having to refer to physiology or personality constructs.
What is:
operant conditioning
6.3.1 Operant Conditioning as an Alternative Description of Personality
When behaviour is changed by its consequences. To do this, Skinner manipulated the environment by shaping successive approximations to do the desired behaviour. This theory emphasizes the study of observable behaviour, environmental conditions, and the process by which environmental events and circumstances determine behaviour; it places emphasis on the function of behaviour over the structure of personality.
What are the assumptions and implications of Skinner’s behaviourism?
6.3.1 Operant Conditioning as an Alternative Description of Personality
- It’s a deterministic theory, in which there’s no free will.
- There is also no “personality” or room for psychical structures (i.e. id, ego, and superego), traits, self-actualization, needs, or instincts. Skinner argued that most behaviour of a person or other organism is conditioned by rewards and punishments, and that these operant behaviours taken together may be what we call personality.
- He took an idiographic approach, and emphasized the individuality of environmental conditions and stressed that we must apply the principles of learning to each organism individually.
- He believed that the universal laws of behaviour acquisition, resulting in what we know as personality, operate in the same manner in humans and nonhuman animals (but more simply in nonhumans).
What is the:
Skinner box
6.3.2 Controlling the Reinforcement
In this enclosure, termed the experimental chamber or operant chamber, the animal (or child) was segregated from all irrelevant environmental influences, expect those under the control of the experimenter. For animals, the box contained either a lever or a key that either released food when triggered (providing positive reinforcement) or stopped the administration of an aversive stimulus like a shock (providing negative reinforcement).
What is Walden Two?
6.3.3 Skinner’s Behaviourist Utopia
In his novel Walden Two (1948), Skinner describes a utopian community that is behaviourally engineered based on principles of operant conditioning. A benevolent government rewards (reinforces) positive, socially appropriate behaviour. Walden Two is problem-free because only positive reinforcement is used; people always behave reliably and responsibly, and they’re very competent. There’s no issue of freedom because Skinner believes free will is only an illusion. He believed that all behaviour is determined anyways, and thus a desirable utopian community is one in which the environment is controleld rather than unstructured.
What is Skinner’s approach to maladaptive behaviours?
6.3.3 Skinner’s Behaviourist Utopia
According to Skinner, psychopathology is learned in the same manner as all other behaviours: reinforcement. People have either not learned the appropriate responses or have learned the “wrong” response. Some individuals may have been punished for adaptive behaviours. Thus, the treatment for “mental illness” is to set up environmental contingencies that reward desirable behaviour. To Skinner, a neurotic is someone who’s been reinforced for overly emotional behaviour.
