Approaches Flashcards
Who was Wilhelm Wundt
- first person to call himself a psychologist
- published first book on psychology - principles of psychological psychology
- his approach paved the pathway for the acceptance of psychology as an distinct science
What was Wundt’s aim
to study the structure of the human mind and the best way to do this was to break down behaviours such as perception and sensation into basic elements
- because of this his approach was referred to as structuralism and he used introspection as a technique
Describe what introspection means?
introspection is when a person gains knowledge about his or her mental health and emotional states, it allows us to observe our inner world
- he believed that with sufficient training mental processes such as memory and perception could be observed systemically as they occurred through perception, this information could be used to gain insight to the inner workings of the mind
What do empiricists believe
- knowledge comes from observation and experience alone, rather than being innate,
- this allowed psychology to become distinct as a science
- based on two major presumptions: first of all the behaviour is seeing as being caused, second if the behaviour is determined than it is possible to predict how they would behave in other conditions = scientific method
What is the scientific method
refers to the use of investigative methods that are objective, systematic and replicable, they sure that they do not let bias or preconceived ideas influence there data,
- have to be replicable and be able to repeat, if not the results cannot be accepted as being universally true
-
Evaluation of The Origins of Psychology: Wundt’s methods were unreliable
- approach relied primarily on nonobservable responses, although participants could report on their conscious experience the process themselves were unobservable constructions
- lack of reliability
- in contrast Pavlov and Thorndike were producing reproducible results
Evaluation of The Origins of Psychology: introspection is not particularly accurate
- most psychologists accept Nisbett and Wilsons 1977 claim that we have little knowledge of the cuases of and processes underlying our behaviour and attitudes, a claim that would challenge the introspection idea,
- found that consumer were unaware of the influences that made them buy and item
Evaluation of The Origins of Psychology: strengths of a scientific approach to psychology
- because of reliance on objective and systamtic methods it can be accepted as fact
- because they rely on determinism they are able to establish cause and effect
- if the scientific theories no longer fit the fact they can be abandoned or changed, therefore it is self corrective, hard for a theory to hold on for long
Evaluation of The Origins of Psychology: limitations of a scientific approach to psychology
- create contrived situations this tells us little about how somebody acts in a natural environment therefore it is lacking ecological validity
- psychology is unobservable therefore cannot be measured by any degree of accuracy
- human behaviour is not subject to the laws and regularities implied by scientific methods then predictions become impossible and methods inappropriate
Evaluation of The Origins of Psychology: introspection is still useful in scientific psychology
- Csikszentmihalyi and Hunter - used introspective methods as measuring a way of happiness, they gave a group of teenagers beepers that went off during the day at random they then had to write down their thoughts and feelings in the moment before the beep
most were unhappy but found when focusing on the challenging task they were more upbeat
Who came up with the idea of classical conditioning
Ivan Pavlov
Who came up with the idea of operant conditioning
Burrhus Skinner
Explain Pavlov’s research (Classical Conditioning)
studying the salivary reflexes in dogs
- he noticed that the dogs salivated when the food was placed in their mouth but also reacted to the stimuli that coincided with the presentation of the food
- the food was the UCS which produced the natural stimulus of salivating which is the UCR
- when the food was paired with the NS a bell over time and through many pairings the NS eventually caused the same response in absence of the UCS
- the NS was now a CS and the response it produced was CR
What are the important features of classical conditioning
- Timing - if the NS cannot be used to predict the UCS, then the conditioning does not take place
- Extinction - Pavlov discovered that unlike the UCS the CR does not become permanently established and after a few presentations of the CS in absence of the UCS it will become extinct
- Spontaneous recovery - following the extinction if the CS and UCS are then paired together once again the link is made more quickly
- Stimulus generation - Pavlov discovered they respond to other stimuli that are similar to the CS
What is positive reinforcement
occurs when behaviour produces a consequence that is stratifying or pleasant for the organism
What is negative reinforcement
work because they remove something aversive and so restore the organism to its “pre-aversive” state
What are other features of operant conditioning, that re important
- schedules of reinforcement - although a continuous reinforcement schedule, is most effective in establishing a particular response a partial reinforcement schedule is more effective in maintaining that response and avoiding extinction
- punishment - refers to the circumstance whereby a behaviour is followed by a consequence that is undesirable or unpleasant for the organism = can be positive or negative
Evaluation The Behaviourist Approach: Strengths of classical conditioning explanations
- lead to reduction of anxiety and phobias
- Systematic desensitisation
Evaluation The Behaviourist Approach: Limitations of classical conditioning explanations
- different species face different challenges to survive so have different capabilities to learn through the process of classical conditioning therefore can be more difficult to establish for some species than others
- animals more prepared to learn things that are significant in terms of their survival
