Approaches in Psychology
Origins of psychology: Wundt, introspection, psychology as a science
Introspection-trained observers were presented with a controlled stimulus, such as a ticking metronome, and asked to describe how it made them think/feel
Wundt’s contributions:
Wrote the first textbook of psychology
Set up the first laboratory of experimental psychology
Used the scientific method to study the structure of sensation and perception
Pioneered the use of introspection as a method to study mental states
The scientific method is:
Objective
Controlled
Replicable
Predictable
Timeline:
1879- Wundt opened the first psychology lab
1900s- Freud and psychodynamic
1913- Behavioural
1950- Humanistic
1960- Cognitive/SLT
1980- Biological
21st century- cognitive neuroscience
Evaluation:
- research was not scientific, as they were not observable behaviours
+ although introspection is not scientific, it is still used today to gain access to cognitive processes
+ Wundt’s methods have been credited as the start of cognitive psychology
+ as Wundt applied the scientific method to studying the mind, it means in modern times, psychology is considered a scientific discipline
Behaviourist approach: classical conditioning and Pavlov’s research, operant conditioning, types of reinforcement and Skinner’s research
Classical conditioning- learning by association. Occurs when two stimuli are repeatedly paired together- an unconditioned stimulus and a new neutral stimulus. The neutral stimulus eventually produces the same response that was first produced by the unconditioned stimulus alone.
Pavlov’s research- found that through pairing the presentation of food with a click sound, the dogs eventually began to salivate upon hearing the click sound on its own
Operant conditioning- a form of learning in which behaviour is shaped and maintained by its consequences
Types of reinforcement:
Positive reinforcement- receiving a reward when a certain behaviour is performed in order to increase this behaviour
Negative reinforcement- avoiding something unpleasant by performing a behaviour, thus increasing the behaviour
Punishment- an unpleasant consequences that decreases the behaviour that it follows
Skinner’s research- a hungry rat was placed in a box that contained a lever that released food when pressed. The consequence of receiving food ensured the rat would repeat the action
Evaluation:
Social learning theory: imitation, identification, modelling, vicarious reinforcement, the role of mediational processes, Bandura’s research
Social learning theory says that people (especially children) learn by observing what people say and do. They are more likely to observe and imitate some people than others, these people are called role models.
Mediational processes:
Attention- the observer must be paying attention to and observing the model
Retention- the observer must be able to remember the behaviour they have seen
Reproduction- the observer must be capable of reproducing the behaviour they have observed
Motivation- if possible rewards are greater than the costs, then the behaviour will be more likely to be imitated by the observer
Bandura’s research:
Children aged 2-6 watched a video of an adult being aggressive to a bobo doll, with different endings
Those who saw the adult being rewarded were more aggressive
Those who saw the adult being punished were less aggressive
Those who saw no ending had medium levels of aggression
Evaluation:
Biological approach: the influence of genes, biological structures, and neurochemistry on behaviour. Genotype and phenotype, genetic basis of behaviour, evolution and behaviour
The biological approach combines psychology and biology to provide explanations for human behaviour
Genes- make up chromosomes and consist of DNA which codes the physical and psychological features of an organism
The biological approach believes that an understanding of biological features and their associated functions can explain psychological processes and characteristics
Two forms of internal communication:
Electrical impulses which travel around our brains, which are transmitted through neurotransmitters
Endocrine system- slower acting communication system which uses hormones released by glands
Genotype- a persons actual genetic makeup. Each person has a unique genotype (except for identical twins)
Phenotype- the way that the genotype of an individual is expressed, through physical and psychological features
Biological psychologists believe that genes may be responsible for certain behaviours
Some psychologists study the genetic basis of behaviour by comparing twins- if MZ twins show a higher likelihood of sharing behaviours/disorders than DZ twins it provides evidence that genes are a cause of that behaviour
Charles Darwin proposed the idea of natural selection to explain evolution
Any behaviour that increases an individuals survival will be passed on to future generations
Aggression is an example of a behaviour that is thought to be naturally selected
Evaluation:
The cognitive approach: internal mental processes, the role of schemas, the use of theoretical and computer models, cognitive neuroscience
The cognitive approach is concerned with the mental processes that occur in between stimulus and response
The role of schema
Schema are “packages” of information, beliefs and expectations in the mind developed through experience. They act as a mental framework for the interpretation of incoming information
Schemas enable us to process lots of information quickly, which is useful as a mental shortcut that prevent us from being overwhelmed
However, schemas may cause errors in the processing of sensory information
They may also lead to depression and other mental disorders
We cannot see mental processes therefore using a model enables psychologists to make inferences about how these mental processes work
Theoretical models are abstract whilst computer models are concrete things
A theoretical model model should never be taken as an exact copy of the thing being described, but rather as an abstract representation of it
Computer models compare the mind to a computer by suggesting there are similarities in the way information is processed
The emergence of cognitive neuroscience:
Cognitive neuroscience is the scientific study of the brain structures, mechanisms and processes that are responsible for cognitive thinking. This involves the mapping of brain areas to specific cognitive functions
PET and fMRI scans now help psychologists to understand how areas of the brain are linked to different cognitive activities and emotions
Cognitive neuroscientists also study atypical brains
Evaluation:
The psychodynamic approach: the role of the unconscious, structure of the personality (id, ego, superego), defence mechanisms (repression, denial, displacement), psychosexual stages
The role of the unconscious
Freud proposed that psychological factors cause mental illness
According to the psychodynamic theory we have an unconscious, which influences our behaviour. Our conscious mind is unaware of thoughts and emotions that occur in the unconscious, however it can have an affect on behaviour
According to Freud, a healthy personality is a balance between the id, ego and superego
Id- the id is entirely selfish, operating at an unconscious level and demanding instant gratification
Ego- tries to strike a balance between satisfying the demands of the id with the expectations of the superego and the outside world
Superego
Incorporates the values and morals we learn from our parents and society. It also contains the conscience
Ego defence mechanisms protect the ego from stressful thoughts and feelings
Repression- pushing bad experiences or negative emotions into the unconscious so you no longer think about them
Displacement- transferring undesirable impulses from one person to another object or another person
Denial- an outright refusal to admit or recognise that anything has happened
Psychosexual stages
Oral
0-1 years
Focus of pleasure is the mouth
Source of conflict is weaning
Anal
1-3 years
Focus of pleasure is the anus
Source of conflict is potty training
The ego develops
Phallic
3-5 years
The focus of pleasure is the genitals
The outcome of the Oedipus and electra complexes affect the development of the superego
Latent phase
6 years- puberty
Period of sexual calm
Genital
Puberty onwards
Establishment of mature relationships
Evaluation:
The humanistic approach: free will, self-actualisation, Maslow’s hierarchy of needs and focus on the self, congruence and conditions of worth. The influence of counselling psychology
Free will- being free to chose what you do and the kind of person you can be
Self actualisation- every person has an innate tendency to self-actualise (achieve their full potential in life)
Maslow hierarchy of needs
A 5 stage model which can be divided into basic needs and higher needs
A person must satisfy the basic needs before progressing to the higher needs, however progress will be disrupted if the lower levels are not met
Focus on the self
According to Roger’s, to self-actualise, we need to receive unconditional positive regard, however most people only receive conditional positive regard
Unconditional positive regard- love is not withdrawn if a person does something wrong
Conditional positive regard- positive love is only given when a person behaves in ways the parents think are correct
Self concept- internal sense of who you are as a person
The ideal self- the person you wish to be/are aiming to become
Congruence- personal growth is achieved when a person is congruent- when their self-concept/ideal self are similar/consistent
The influence of counselling psychology
Roger’s developed client-centred therapy
The job of the therapist is to provide genuineness, empathy and unconditional positive regard
