Approaches in Psychology Flashcards
(106 cards)
Outline the role of Wundt in the origins of psychology
- The first psychology lab was opened in Leipzig, Germany
- Aim of psychology was to describe the “nature of human consciousness” in a carefully controlled, scientific environment
Define introspection
The first systematic experimental attempt to study the mind
Outline the role of standardised procedures in the origins of psychology
- The same standardised instructions were given to all participants and stimuli (objects or sounds) were presented in the same order
- For example, participants were given a ticking metronome and they would report their thoughts, images and sensations, which were then recorded
Define structuralism
- Introspection led to identifying the structure of consciousness by breaking it up into the basic structures : thoughts, images and sensations
- This marked the beginning of SCIENTIFIC PSYCHOLOGY, separating it from its broader philosophical roots
What were the early behaviourists’ (e.g. Watson) views on introspection and psychology (1900s)
- Rejected introspection
- Watson argued introspection was SUBJECTIVE because it’s influenced by a personal perspective
- According to the behaviourist approach, “scientific” psychology should only study phenomena that can be observed and measured
Outline how the behaviourist approach (1930s) dominated psychology for 50 years
- Skinner brought the language of the natural sciences into psychology
- The behaviourists focussed on learning, and the use of carefully controlled lab studies, which would dominate psychology for 50 years
Outline how the cognitive approach (1950s) viewed psychology following the computer revolution
- Cognitive approach studied mental processes scientifically
- Following the computer revolution of the 1950s, the study of mental processes was seen as legitimate within psychology
- The mind was likened to a computer and psychologists tested predictions about memory and attention using experiments
Outline how the biological approach (1980s) viewed psychology after introducing technological advances, e.g. fMRI
Biological psychologists have taken advantage of recent advances in technology, including recording brain activity by using scanning techniques, e.g. fMRI, EEG and using advanced genetic research
Aspects of Wundt’s work are scientific. How is this a strength of the emergence of psychology as a science?
- He recorded the introspections within the controlled lab environment
- He also standardised his procedures so that all participants received the same information and were tested in the same way
- Therefore, Wundt’s research can be considered a forerunner to the later scientific approaches
Aspects of Wundt’s work are subjective. How is this a weakness of the emergence of psychology as a science?
- Wundt relied on participants self-reporting their “private” mental processes. Such data is subjective, as participants may have hidden some of their thoughts
- This makes it difficult to establish meaningful “laws of behaviour”, one of the aims of science
- Therefore, Wundt’s early efforts to study the mind were naïve and would not meet the criteria of scientific enquiry
Wundt made a significant contribution to psychology. How is this a strength of the emergence of psychology as a science?
- Wundt produced the first academic psychology journal and wrote the first psychology textbook
- He is often referred to as “the father of psychology”
- His pioneering research set the foundation for approaches that were to come, particularly the behaviourist and cognitive approaches
- This shows that, despite the flaws in his early experimental research, Wundt made a significant contribution to psychology
Research in modern psychology can claim to be scientific. How is this a strength of the emergence of psychology as a science?
- Psychology has the same aims as the natural sciences - to describe, understand, predict and control behaviour
- Learning, cognitive and biological approaches all use scientific methods, e.g. lab studies are controlled are unbiased
- Throughout the 20th century and beyond, psychology has established itself as a scientific discipline
Some approaches use subjective data. How is this a weakness of the emergence of psychology as a science?
- Humanistic approach doesn’t formulate general laws of behaviour
- Psychodynamic approach uses case studies with unrepresentative samples
- Psychologists study humans who are active participants and therefore respond to demand characteristics
- Therefore, a scientific approach to the study of human thought and experience is not desirable or possible
Psychology does not have a clear paradigm, and therefore may not class as a science. How is this a weakness of the emergence of psychology as a science?
- Kuhn said that any science must have a paradigm - a set of principles, assumptions and methods that all people who work within that subject agree on
- Psychology does not have a paradigm, HOWEVER, most would agree it’s the study of mind and behaviour
- This suggests that the question of whether psychology is a science remains unanswered
Outline the key features of the behaviourist approach
- Only focusses on observable and measurable behaviour - rejected introspection because of its vague and immeasurable concepts
- Controlled lab studies - tried to maintain control and objectivity in their research
- Used non-human animals as test subjects - behaviourists suggest the learning processes are the same in all species, so animals can replace human as test subjects
Outline classical conditioning through the use of Pavlov’s dogs
Outline operant conditioning through Skinner’s research with rats
- Behaviour is shaped and maintained by its consequences
- When a rat activated a lever, it was rewarded with a food pellet
- A positive consequence led to a behaviour being repeated (POSITIVE REINFORCEMENT)
- If pressing a lever meant the rat would avoid an electric shock, the behaviour would also be repeated (NEGATIVE REINFORCEMENT)
Describe the 3 consequences of behaviour
- POSITIVE REINFORCEMENT - receiving a reward when behaviour is performed
- NEGATIVE REINFORCEMENT - avoiding something unpleasant when behaviour is performed
- PUNISHMENT - an unpleasant consequence of behaviour
Positive and negative reinforcement increase the likelihood that behaviour will be repeated. Punishment decreases it
Behaviourism uses well-controlled research. How is this a strength of the behaviourist approach?
- This approach has focussed on the careful measurement of observable behaviour within controlled lab settings
- Behaviourists have broken behaviour down into “stimulus - response” units and studied causal relationships
- This suggests that behaviourist experiments have scientific credibility
The behaviourist approach may oversimplify learning. How is this a weakness?
- It may ignore important influences on behaviour, (e.g. thought) and sees the mind as a BLACK BOX
- Other approaches, e.g. SLT and cognitive include mental processes
- This suggests learning is more complex than just what we observe
The behaviourist laws of learning have real world application. How is this a strength of the behaviourist approach?
- The principles of conditioning have been applied to a broad range of real world behaviours and problems
- TOKEN ECONOMY SYSTEMS reward appropriate behaviour with tokens that are exchanged for privileges (operant conditioning). Successfully used in prisons and psychiatric wards
- This increases the value of the behaviourist approach because it has widespread application
Behaviourism is a form of environmental determinism. How is this a weakness of the behaviourist approach?
- The approach sees all behaviour as determined by past experiences that have been conditioned and ignores any influence that free will may have on behaviour
- Skinner suggested that free will was an illusion. When something happens, we may think “I made the decision to do that”, but our past conditioning determined the outcome
- This is an extreme position and ignores the influence of conscious decision making processes on behaviour (as suggested by the cognitive approach)
How are ethical issues regarding the Skinner box study a weakness of the behaviourist approach?
- Procedures such as the Skinner box allowed behaviourists to maintain a high degree of control over their experimental “subjects”
- HOWEVER, the animals were housed in harsh, cramped conditions and deliberately kept below their natural weight so they were always hungry
- Therefore, there is a question of benefits vs costs - some would argue that there have been enormous benefits (e.g. application the therapy) which offsets the harm the animals experienced
Outline the key features of Social Learning Theory (SLT)
- Learning that occurs indirectly - Bandura agreed with the behaviourist approach that learning occurs through experience. HOWEVER, he also proposed that learning occurs in a social context through observation and imitation of others’ behaviour
- Vicarious reinforcement - children and adults observe people’s behaviour and take note of its consequences. Behaviour that is seen to be rewarded is more likely to be copied
- Mediational processes - play a crucial role in learning
- Identification with role models - people are likely to imitate the behaviour of those with whom they identify. Such role models are similar to the observer, attractive and have high status
