ORIGINS OF PSYCHOLOGY
Fill in the blanks:
In 1879, Wilhelm [ ] opened the first ever [ ] dedicated to [ ] [ ] in a little town called Leipzig in [ ] . His work was significant because it marked the beginning of [ ] [ ] , separating it from its broader roots of [ ] [ ] . His aim was to try and analyse the nature of human [ ] , and thus represented the first systematic attempt to study the [ ] under [ ] conditions. His pioneering method became known as [ ] .
In 1879, Wilhelm Wundt opened the first-ever lab dedicated to psychological enquiry in a little town called Leipzig in Germany. His work was significant because it marked the beginning of scientific psychology, separating it from its broader roots of experimental philosophy. His aim was to try and analyse the nature of human consciousness and thus represented the first systematic attempt to study the mind under controlled conditions. His pioneering method became known as introspection.
ORIGINS OF PSYCHOLOGY
What is introspection and how did Wundt do it?
Introspection is the first systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures of thoughts, images and sensations
- he and his co-workers recorded their experiences of different objects (ticking metronome) or sounds and divided them into thoughts, images and sensations
- structuralism: isolating the structure of conscious awareness by always being presented in the same order and the same instructions given to all ptps
ORIGINS OF PSYCHOLOGY
Evaluate (one strength, one weakness) Wundt’s contribution to psychology
STRENGTH: scientific
- systematic methods, well-controlled, i.e. scientific
- all introspections done in the controlled lab environment
- => extraneous variables controlled for
- procedures standardised (everyone tested in the same way)
FURTHERMORE: father of psychology, first scientific psychological journal
THEREFORE: Wundt’s research can be considered a forerunner to later scientific approaches, e.g. behaviourist and cognitive
LIMITATION: subjective data
- considered unscientific today
- self-report = subjective data, some ptps may have hidden some of their thoughts
- difficult to establish meaningful ‘laws of behaviour’ from subjective data: general laws are useful to predict future behaviours which is an aim of science
~~> Wundt’s early efforts to study the mind were flawed and wouldn’t meet the criteria of scientific enquiry
ORIGINS OF PSYCHOLOGY
Outline the emergence of psychology as a science, referencing 1900s, 1950s and 1980s
1900s Behaviourists
- value of introspection was questioned by many (because of the subjective data and difficulty to establish general laws) including Watson
- Watson and Skinner: truly scientific psychology should only study phenomena that can be observed objectively and measured
- behaviourists dominated for next 50yrs
1950s Cognitive Approach
- digital revolution => metaphor for studying the mind
- said the mind was “like a computer” (like multi-store model)
- tested predictions about memory and attention using experiments
- ensured study of mind was legitimate and highly scientific
1980s Biological Approach
- taken advantage of advances in technology to investigate psychological processes (live) as they happen, e.g. brain scans
- genetic testing => better understanding of relationship between genes and behaviour
ORIGINS OF PSYCHOLOGY
Evaluate (one strength, one limitation) the emergence of psychology as a science
STRENGTH: modern psychology is scientific
- same aims as natural sciences: to describe, understand, predict and control behaviour
- learning, cognitive and biological approaches use scientific methods (lab studies)
~~> throughout 20th century and beyond, psychology has established itself as a scientific discipline
HOWEVER: lacking in paradigm (a set of principles, methods and assumptions that everyone agrees on) due to too much internal disagreement
THEREFORE: scientific status threatened
LIMITATION: subjective data
- not all approaches use objective methods
- humanistic rejects the scientific approach, preferring to focus on individual and subjective experiences
- psychodynamic makes use of case studies which are unrepresentative
- humans as the subject of study makes our research vulnerable to demand characteristics
THEREFORE: scientific approach to the study of human behaviour isn’t always possible or desirable
LEARNING APPROACHES: THE BEHAVIOURIST APPROACH
Outline the 4 assumptions of the behaviourist approach
- studying observable behaviour
- aim for more control and objectivity (therefore lab studies are ideal)
- basic processes of learning are the same in all species (therefore we can use animals as subjects in experiments)
- all behaviour is learned, as babies we are ‘blank slates’
LEARNING APPROACHES: THE BEHAVIOURIST APPROACH
Outline the 2 key theories of the behaviourist approach, determined by Pavlov and Skinner
CLASSICAL CONDITIONING
- learning through association
before:
- UCS (food) -> UCR (salivation) (generally a reflex)
- NS (bell) -> no response
during:
- UCS (food) + NS (bell) -> UCR (salivation)
- this is repeated until…
after:
- (NS (bell) has now become the:) CS -> (UCR (salivation) has now become the:) CR
OPERANT CONDITIONING
- learning is an active process
- humans and animals behave according to their environment in terms of the consequences of their behaviours:
- positive reinforcement: desirable behaviour is rewarded
- punishment: an undesirable behaviour is met with an unpleasant consequence
- negative reinforcement: finding a way to avoid the unpleasant consequence
- +ve and -ve reinforcement both increase the likelihood that a behaviour will be repeated and punishment decreases the likelihood that behaviours will be repeated
LEARNING APPROACHES: THE BEHAVIOURIST APPROACH
Outline one strength of the behaviourist approach, regarding its scientific nature.
P: One strength of the behaviourist approach is that it is scientific.
E: For example, behaviourism brought about language and methods of natural sciences into Psychology by studying observable behaviour in highly controlled lab settings by conducting experiments on animals (i.e. Pavlov’s dogs and Skinner’s rats).
E: This is a strength because it emphasises the importance of scientific processes such as objectivity and replication which are key features when defining what a science really is. This therefore strengthens Psychology’s claim to being a science.
E: However, animal studies, though they are scientific, have limited generalisability to humans because we have more complex functioning and more complex brains which govern our behaviour than rats or dogs do. Therefore despite the behaviourist approach being scientific, psychologists must be cautious when making claims about human behaviour that have an evidence base in animal studies.
L: As a result, the credibility of the behaviourist approach is increased but only to a certain extent due to a flaw in the generalisability of their research, despite it being scientific.
LEARNING APPROACHES: THE BEHAVIOURIST APPROACH
Outline one limitation of the behaviourist approach, regarding environmental determinism.
P: One limitation of the behaviourist approach is that it is environmentally deterministic.
E: For example, this approach views all behaviour as determined by past experiences that have been conditioned. Skinner suggested that everything we do is the sum of our reinforcement history.
E: This is a weakness because it ignores any possible influence of free will on our behaviour. Skinner suggested that any sense of free will is an illusion; when something happens we impose a sense of having made the decision but, according to Skinner, our past conditioning history actually determined the outcome. This is a pessimistic view of human behaviour and implies that we have no active role in our behaviour, an idea that lacks intuitive plausibility.
E: However, one strength of environmental determinism is that we can establish a causal relationship because we assume that, for example, past experiences cause our current behaviour. This allows for a better understanding of human behaviour and can have real-world application in the treatment of debilitating disorders like phobias (which we treat with classical conditioning).
L: As a result, the credibility of the behaviourist approach is increased but only to an extent due to the restricted view of human behaviour.
LEARNING APPROACHES: THE BEHAVIOURIST APPROACH
Outline one strength of the behaviourist approach, regarding real-world application.
P: One strength of the behaviourist approach is that it has real-world application.
E: For example, operant conditioning has been used to develop token economy systems in prisons and psychiatric wards (where prisoners/patients are rewarded with tokens they can exchange for goods when they display a desirable behaviour) and classical conditioning has been used in the treatment of phobias.
E: This is a strength because it suggests that the behaviourists are accurate in their assumptions and that we can use these understandings to aid and better the existence of humans to allow for better lifestyles and treatments of potentially debilitating disorders.
E: Furthermore, the application of behaviourist concepts in the treatment of phobias has positive implications for the economy. This is because we can provide treatment for the disorder that previously made them unable to work, which means that when they return to work with an improved quality of life, they are able to contribute once again to the economy, further emphasising the benefits of the behaviourist approach.
L: As a result, the credibility of the behaviourist approach is increased due to real-world application.
LEARNING APPROACHES: SOCIAL LEARNING THEORY
Outline the 2 assumptions of Social Learning Theory (SLT) as determined by Bandura
- we learn through observation and imitation of others
- learning occurs directly, i.e. CC and OC, but also indirectly
LEARNING APPROACHES: SOCIAL LEARNING THEORY
Outline the 3 key theories of SLT, as determined by Bandura
VICARIOUS REINFORCEMENT:
- imitation occurs if the behaviour of another individual is seen to be rewarded rather than punished
MEDIATIONAL PROCESSES:
1) attention: noticing behaviours
2) retention: remembering behaviours
3) motor reproduction: ability of observer to perform the behaviour
4) motivation: the will to perform the behaviour, often determined by whether the behaviour was rewarded or punished
IDENTIFICATION:
- people (esp children) are more likely to imitate people that they identify with (role models)
- role model: same gender, attractive, higher status
- process of imitating a role OR the role model demonstrating a behaviour is called modelling
- role models can be live (in person) or symbolic (via tv etc.)
LEARNING APPROACHES: SOCIAL LEARNING THEORY
Describe Bandura’s (1961) original/first bobo doll study
children observed adult hit a bobo doll with a hammer and shout abuse at it
children later behaved more aggressively towards the bobo doll than those who had observed a non-aggressive adult
LEARNING APPROACHES: SOCIAL LEARNING THEORY
Describe Bandura and Walters’ (1963) second bobo doll study
- showed videos to children of adults behaving aggressively towards bobo doll
- group 1 saw adults praised for their behaviour (told “well done”)
- group 2 saw adult punished for aggression (told off)
- control group: saw aggression with no consequence
- when given own bobo doll to play with, group 1 showed most aggression, then control group, then group 2
LEARNING APPROACHES: SOCIAL LEARNING THEORY
Evaluate SLT
STRENGTH: recognises cognitive factors
- CC and OC alone don’t offer an adequate explanation of learning
- humans and animals store info about behaviour of others and use this to make judgements about when it is appropriate to perform certain actions
- Bandura: “learning would be hazardous if we relied solely on the consequence of our own actions”
~~> SLT provides a more comprehensive explanation of human learning by recognising the role of mediational processes
HOWEVER: not enough reference to biological factors
- Bandura: “biological differences influence our learning potential, but learning itself is governed by the environment”
- however research suggests that observational learning may be the result of mirror neurons in the brain which allow us to empathise with and imitate other people
~~> biological influences on social learning were under-emphasised in SLT
STRENGTH: supportive evidence from bobo doll study
- showed rewarded behaviour observed from others is more likely to lead to imitation of behaviour than no consequence or punishments
HOWEVER: contrived (artificial/strained/obviously planned) lab studies
- many of Bandura’s ideas were developed through observation of young children’s behaviour in the lab
- contrived nature has been criticised => demand characteristics
- regarding bobo doll study: could be argued that the main purpose of the doll was to strike it so the children were simply behaving in a way they thought was expected
~~> research may tell us little about how children actually learn aggression in everyday life
STRENGTH: real-world application
- explains cultural differences in behaviour; modelling, imitation and reinforcement can account for how many children learn from others around them/in the media => explains how norms are transmitted through societies
~~> increases value of approach; accounts for real-world behaviour
FURTHERMORE: age restrictions on games and movies
LEARNING APPROACHES: SOCIAL LEARNING THEORY
Outline one strength of social learning theory, regarding the importance of cognitive factors in learning.
P: One strength of social learning theory is that it offers a more adequate account of learning than other (behaviourist) perspectives
E: For example, it considers that humans and other animals do store information about the behaviour of others (by observing) and then use this information to make their own judgements about when it is appropriate to perform certain actions (imitation). In addition, SLT also recognises the role of mediational processes. Bandura himself said “learning would be hazardous if we relied solely on the consequence of our own actions”
E: This is a strength because SLT provides a more comprehensive explanation of learning by recognising these mediational processes. Neither classical or operant conditioning can offer an adequate account of learning on their own.
E: However, there isn’t enough reference to biological factors for SLT to be a completely comprehensive explanation of behaviour. For example, Bandura said that “biological differences influence our learning potential, but learning itself is governed by the environment.” Yet, research suggests that observational learning may be the result of mirror neurons in the brain which allow us to empathise with and imitate other people. This suggests that any biological influences on social learning were under-emphasised in SLT.
L: As a result, the credibility of social learning theory is increased but only to a certain extent because it offers a more comprehensive understanding of behaviour than behaviourists but is not fully encompassing of all factors involved in influencing our behaviour.
COGNITIVE APPROACH
Outline the 3 assumptions of the cognitive approach
- internal processes can and should be studied scientifically
- investigates private and unobservable processes that were neglected by behaviourists (e.g. memory perception and thinking)
- studying these indirectly by making inferences about the mind based on behaviour
COGNITIVE APPROACH
Outline the theory of schemas in the cognitive approach
SCHEMA: a mental framework of beliefs and expectations that influence cognitive processing, developed from experience
- “packages” of ideas and info learned from experience
- e.g. schema for a chair: 4 legs, you can sit on it
- schemas help you respond appropriately to a stimulus
- babies are born with simple motor schema for innate behaviours (grasping, sucking)
- schemas become more detailed and complex as we get older
- they help us to process lots of info quickly; helpful as a mental shortcut that prevents us from being overwhelmed by environmental stimuli
BUT schemas can distort our interpretation of sensory info => perceptual errors
COGNITIVE APPROACH
Outline the theory of theoretical and computer models in the cognitive approach
- cognitive psychologists use theoretical and computer models to help them understand internal mental processes
- in reality, these models overlap; but theoretical models are abstract, computer models are concrete things
theoretical model example: ‘info processing approach’
- info flows through cognitive system in a series of stages, input, storage, retrieval (like in MSM of memory)
- this approach is based on the way a computer functions
computer model:
- programming a computer to see if such instructions produce a similar output to humans
- if they do then we can suggest that similar processes are going on in the human mind
- such computer models have proved useful for development of AI
COGNITIVE APPROACH
Outline the emergence of cognitive neuroscience
cognitive neuroscience: scientific study of brain structures on mental processing
- Mapping brain areas to functions started in 1860s: Broca’s area => speech production (or impairment of)
- in last 25 years: brain imaging techniques (fMRI & PET scans) => we can systematically observe and describe the neurological basis of mental processes
- e.g. Buckner and Peterson (1996): episodic and semantic memory stored on different sides of prefrontal cortex
- e.g. Braver et al (1997): central executive thought to reside in prefrontal cortex or a similar area
- scanning techniques have proven useful in establishing neurological basis => link between parahippocampal gyrus and OCD (appears to play a role in processing unpleasant emotions)
- the focus of cognitive neuroscience has expanded recently, including use of computer-generated model that are designed to ‘read the brain’ => development of mind-mapping techniques (brain fingerprinting) (possible future application of this is analyse brain wave patterns of eyewitnesses as a lie detector in courts)
COGNITIVE APPROACH
Evaluate the cognitive approach
STRENGTH: scientific methods, objective
- lab studies; highly controlled methods => able to infer cognitive processes at work
- cognitive neuroscience => biology + cognitive => increased scientific basis of approach
~~> study of the mind has a credible scientific basis
HOWEVER: potentially too theoretical
- relies on inferences of mental processes => often theories
- often artificial stimuli were used in experiments (memory tests with word lists) => unrepresentative of everyday experiences
~~> research on cognitive processes has low external validity
THEREFORE: decreased cred to an extent due to scientific nature but flawed key theories
STRENGTH: real-world application
- cognitive approach is dominant in psychology today => e.g. contribution to field of AI, contribution to treatment of depression, improved reliability of EWTs
~~> supports value of cognitive approach
PLUS: +VE implications for economy if patients are able to return to work due to reduced struggles with depression/reduced severity of symptoms
THEREFORE: cred increased due to real-world application
LIMITATION: machine reductionism
- computer analogy ignores influence of human emotion and motivation on cognitive system which may affect our ability to process info
- e.g. human memory impacted by anxiety (EWTs)
~~> machine reductionism weakens validity of cognitive approach
BUT: soft determinism
- appreciates role of free will and determinism
- thoughts are ‘freely’ chosen but only within the limits of our knowledge and experience
THEREFORE: cred increased to due appreciation of realistic balance
THE BIOLOGICAL APPROACH
Outline the 3 assumptions of the biological approach
- everything psychological is at first biological
- studying biological structures and processes within the body
- the mind lives in the brain: all thoughts, feelings and behaviour ultimately have a physical basis (contrast to cognitive approach where mind and brain are separate)
