Approaches Flashcards
Define psychology
The scientific study of the human mind and its functions, especially those functions affecting behaviour in given contexts
Define science
A means of acquiring knowledge through systematic and objective investigation. The aim is to develop general laws.
Define introspection
A systematic method used to study the mind by breaking up conscious awareness into basic structures of thoughts, images and sensations.
Who opened the first ever lab dedicated entirely to psychological enquiry?
Wilhelm Wundt
Where was Wundt’s lab and when did he open it?
- Leipzig, Germany - Opened in 1879
Why was Wundt opening his lab significant?
It marked the beginning of scientific psychology, separating it from its broader philosophical roots.
What was Wundt’s aim?
To try to analyse the nature of human consciousness (introspection)
Detail some of Wundt’s investigations
- He trained participants to introspect (ie: objectively observe their own thoughts and sensations) - He then placed a stimulus before the participants (ie: a metronome) - He had the report on their thoughts, images and sensations in response to it
How does Wundt’s research link to structuralism?
- He isolated the structure of consciousness - The stimuli were always presented in the same order and the same instructions were issued to all participants
Explain how Wundt’s method of investigating human experience could be considered scientific
- It was highly controlled (the stimulus would last a specific period of time, the responses were carefully recorded, the participants were carefully trained) - It was replicable
Explain how Wundt’s method of investigating human experience could be considered unscientific
- It could be repeated over and over again, but responses were so varied that no general principles could be established
What was psychology considered to be from the 17th to the 19th century?
- A branch of the broader discipline of philosophy - Known as experimental philosophy
What two approaches dominated the 1900s until around the 1950s?
- Behaviourism - Psychodynamic
Who founded the psychodynamic approach?
Freud
Summarise the psychodynamic approach
- Freud emphasised the influence of the unconscious mind on behaviour - Freud developed person-centred therapy: psychoanalysis - Was unscientific and contains falsifiable concepts
Name the influential behaviourists
- John B. Watson - Skinner
Summarise the behaviourist approach and why it emerged
- The value of introspection was questioned at the beginning of the 20th century because it produced subjective data that can’t help establish general laws - Behaviourists proposed that a truly scientific psychology should only study phenomena that can be observed objectively and measured - Behaviourists focus on behaviours they could see and used carefully controlled experiments
When was the cognitive revolution?
1950s and 60s
What two approaches were developed in the 1950s?
- Humanistic - Cognitive
Who developed the humanistic approach?
- Rogers - Maslow
Summarise the humanistic approach
- It rejected the behaviourist and psychodynamic view that human behaviour is determined by outside factors - Emphasises the importance of self determination and free will - Rejected science
Summarise the cognitive approach and why it was developed
- The digital revolution of the 1950s allowed psychologists to liken the mind to a computer - Involved testing their predictions about memory and attention with experiments - Made the study of the mind scientific again - Led to the development of neuroscience
What approach was developed in the 1960s?
Social learning theory
Who developed social learning theory?
- Bandura
Summarise social learning theory
- Draws attention to the role of cognitive factors in learning - Provided a bridge between the newly established cognitive approach and traditional behaviourism
What approach was developed in the 1980s?
Biological approach
Summarise the biological approach and why it was created
- Advances in technology increased understanding of the brain and biological processes - Links to cognitive neuroscience
What discipline emerged at the eve of the 21st century?
Cognitive neuroscience
What does cognitive neuroscience investigate?
How biological structures influence mental states
What types of behaviour is the behaviourist approach only interested in studying?
Behaviour that can be observed and measured.
Why do behaviourists reject introspection?
It involves too many concepts that are vague and difficult to measure.
Why were animals able to replace humans in experiments for the behaviourist approach?
After Darwin, behaviourists suggested that the basic processes that govern learning are the same in all species.
What are the two forms of learning identified by behaviourists?
Classical conditioning and operant conditioning
Define classical conditioning
Classical conditioning involves learning to associate two stimuli together so we begin to respond to one in the same way we already respond to the other.
Who experimented with classical conditioning?
Pavlov
Outline Pavlov’s experiment into classical conditioning
He gave his dog food and it salivated. He then rang a bell when he gave the dog food. Eventually, the dog salivated at the bell alone.
What was the food in Pavlov’s experiment?
The unconditioned stimulus
What was the unconditioned response in Pavlov’s experiment?
The dog salivating at the food
What was the bell in Pavlov’s experiment introduced as and what did it turn into?
Introduced as: neutral stimulus Turned into: conditioned stimulus
What is the conditioned response in Pavlov’s experiment?
The dog salivating at the sound of a bell
Which psychologist contributed to the definition of operant conditioning?
Skinner
What did Skinner say operant conditioning is?
A form of learning in which behaviour is shaped and maintained by its consequences.
What are the four types of consequence in operant conditioning?
- Positive reinforcement - Negative reinforcement - Positive punishment - Negative punishment
What does reinforcement do?
Increases the likelihood of a behaviour being repeated
What does punishment do?
Decreases the likelihood of a behaviour being repeated
What does positive reinforcement entail?
Adding a pleasant stimulus to increase/maintain the behaviour
What does negative reinforcement entail?
Removing an unpleasant stimulus to increase/maintain the behaviour
What does positive punishment entail?
Adding an unpleasant stimulus to decrease the behaviour
What does negative punishment entail?
Removing a pleasant stimulus to decrease the behaviour
Give an example of positive reinforcement
Being given a lollipop
Give an example of negative reinforcement
Avoiding doing chores
Give an example of positive punishment
Get a smack
Give an example of negative punishment
Confiscation of your phone
What was Skinner’s experiment called?
The Skinner Box
Outline the method of the Skinner Box experiment
- Used rats and sometimes pigeons - Put them in specially designed cages - Every time a rat activated a lever (or the pigeon pecked a disk) it was rewarded with a food pellet - From then on the animal would perform the behaviour - He also showed that rats and pigeons could be conditioned to perform the same behaviour to avoid an unpleasant stimulus (eg: an electric shock)
Name the strengths of the behaviourist approach
- Scientific credibility - Real life applications
Name the weaknesses of the behaviourist approach
- Too mechanistic - Environmentally deterministic
Why is behaviourism scientifically credible?
- It used controlled investigations which produced patterns that could be created into the general law of conditioning - Science should produce patterns/principles that can be applied to anyone - It emphasised the importance of scientific processes such as objectivity and replication
Give some examples of real life application of behaviourism
- Operant conditioning: token economy systems have been used in institutions such as prisons and psychiatric hospitals. These work by rewarding appropriate behaviour with tokens that can be exchanged with privileges. - Classical conditioning: systematic desensitisation is used to treat phobias. It counters the initial conditioning (the phobic stimulus paired with a traumatic event)
How is the behaviourist approach mechanistic?
- Animals and humans are seen as passive and machine like responders to environment - It suggests that our behaviours are merely reflex actions to what happens in our environment
Why is being too mechanistic a weakness of the behaviourist approach?
- It undermines the complexity of human beings - It ignores factors such as cognition and emotion which drive our behaviour - There is evidence that the cognitive processes mediate between exposure to our environment and the behaviour we produce. The behaviourist approach doesn’t account for this.
How is the behaviourist approach environmentally deterministc?
- It suggests that environmental factors (which are out of our control) determine our behaviour
Why is it a weakness that the behaviourist approach is environmentally deterministic?
- It suggests that we do not consciously control ourselves and undermines the notion of free will - It ultimately presents a pessimistic view of human nature which isn’t in line with our everyday experiences of making choices
Who founded social learning theory?
Bandura
How does social learning theory state we learn?
- Through observation and limitation of others within a social context - We learn directly (through classical and operant conditioning) but also indirectly
Define vicarious reinforcement
Seeing others being reinforced or punished for a behaviour influences our motivation to copy that behaviour. This learning can happen indirectly (or vicariously).
What did Bandura define mediational processes as?
The cognitive factors (ie: internal mental processes) which mediate between the observation of a behaviour and the acquisition (copying of) the behaviour. These mediational processes determine whether or not you will copy someone else’s behaviour.
Name the four mediational processes identified by Bandura
- Attention 2. Retention 3. Motor reproduction 4. Motivation
What is involved in the mediational process: attention?
Noticing the behaviour
What is involved in the mediational process: retention?
Remembering the behaviour
What is involved in the mediational process: motor reproduction?
Our perceived ability to perform the behaviour
What is involved in the mediational process: motivation?
The extent to which you want to perform the behaviour
What is identification?
The process in which a person patterns his thoughts, feelings, or actions after another person who serves as a model.
How is identification usually investigated in research?
By measuring how similar the participant feels they are to their role model
What is modelling?
When someone acts as a role model for which someone can copy behaviours from.
Why might someone model their behaviour on someone else’s?
- They look up to them - Others have a good reaction to it - They have high status
Outline Bandura’s bobo doll experiment
- He recorded the behaviour of young children who watched an adult behave in an aggressive way towards a bobo doll - The adult hit the doll with a hammer and shouted abuse at it - When the children were later observed playing with various toys, they behaved much more aggressively towards the doll and the other toys than those who had observed a non aggressive adult
Name the strengths of social learning theory
- It is more holistic than other approaches - Explains cultural differences in behaviour
Name the weaknesses of social learning theory
- Over reliance on evidence from lab studies - Underestimating the influence of biological factors
How does social learning theory explain cultural differences in behaviour?
- It accounts for how children learn from other individuals around them, as well as through media - It explains how cultural norms are transmitted through certain societies - Eg: gender norms
How is social learning theory more holistic than other approaches such as the behaviourist approach?
It explains behaviour from more than one level of explanation: - The lower ‘stimulus and response’ level - The higher level of actual cognitive processes
Why is social learning being holistic a strength?
- It provides a more comprehensive view of where behaviours come from - It acknowledges the complexity of behaviour
Why is the fact that many of Bandura’s experiments were lab experiments a weakness?
- They are contrived - Participants may respond to demand characteristics - The research can’t be applied to children’s everyday life behaviour
How are biological factors underestimated by social learning theory?
- The bobo doll experiment consistently found that boys were more aggressive than girls, regardless of the specifics of the experimental situation - This could be explained by hormonal factors (ie: difference in testosterone levels)
How does the cognitive approach say that mental processes should be studied?
Scientifically
What are internal mental processes?
The private operations of the mind that mediate between stimulus and response
Give examples of internal mental processes that the cognitive approach studies
- Memory - Attention - Problem solving - Emotion - Intelligence - Learning - Perception
What does it mean to make an inference?
To draw conclusions about the way mental processes operate on the basis of observed behaviour
How is the cognitive approach scientific?
- It is more objective as results are simple, clear and quantitative - It has produced general laws and principles (eg: memory can only hold 7+/-2 pieces of info)
Name 2 ways of studying internal mental processes
- Use of theoretical models - Use of computer models
Name three qualities of a theoretical model
- The theories are in stages (and so are often presented as diagrams) - They are testable (you can use them to make inferences about internal mental processes by absorbing behaviour) - You can change or refine them if the observed behaviour doesn’t fit the model
Give an example of a theoretical model
The information processing approach, which suggests that information flows through the cognitive system in a sequence of stages that include input, storage and retrieval, as in the multistore model.
What is involved in a computer model?
- The mind is compared to a computer by suggesting that there are similarities in the way information is processed. - These models compare the central processing unit to the brain, coding to turning information into a usable format and the use of stores to hold information
List how computers can be compared to the mind
- Input - Process - Output - Hardware - Software - Memory storage
What is a schema?
- A package of ideas, information and expectations of the world around us, developed through experience - They act as mental framework for for the interpretation of incoming information received by the cognitive system
Why are schemas useful?
- They allow us to process a lot of information quickly so we are not overwhelmed by environmental stimuli - They allow us to take shortcuts in interpreting the vast amount of information that is available in our environment
Why can schemas be negative?
- They can cause us to exclude relevant or important information to focus instead only on things that confirm our pre-existing beliefs - They can contribute to stereotypes - They make it difficult to retain new information that doesn’t confirm our established existence in the world
What is cognitive neuroscience?
The scientific study of the biological processes that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes.
Give three examples of how the brain is linked with cognition
- The frontal lobe is responsible for intelligence, decision making, planning, judgement, logical thinking - The parahippocampal gyrus is responsible for processing unpleasant emotions - Semantic memories are stored in the hippocampus
Name three practical applications of the cognitive approach
- Identifying which brain structures/neural pathways are associated with which cognitions (internal mental processes) - Identifying brain structures/neurotransmitters which are associated with psychological disorders, which opens up the way for treatment - Artificial intelligence: attempting to replicate neural processes in a machine in order to stimulate human-like cognition
Name the strengths of the cognitive approach
- It is scientific - Practical applications - It is founded on soft determinism
Name the weakness of the cognitive approach
- It is too mechanistic
How is cognitive psychology scientific?
- It employs highly controlled and rigorous methods of study so researchers can infer cognitive processes - Lab studies are frequently used - The emergence of cognitive neuroscience has enabled biology and cognitive psychology to come together in a scientific manner
What is a counterpoint to the strength of cognitive psychology being scientific?
- It relies on the inference of mental processes rather than direct observation of behaviour so it can sometimes suffer from being too abstract - Lab studies often use artificial stimuli
