Paper 2 - Approaches Flashcards
What is psychology
The scientific study of the human mind and its functions, especially those functions affecting behaviour in a given context
Where does the word psychology come from
The Greek word ‘psych’ meaning ‘mind’ and the Greek word ‘logos’ meaning ‘study of’
Who established the first psychology lab
Wilheim Wundt
Where and when did Wundt open his psychology lab
Germany in 1879
What was Wundts aim
To describe the nature of human consciousness
What did Wundt pioneer
The method of introspection - the same standardised instructions were given to all participants so the procedures could be replicated (controlled conditions)
What is introspection
The first systematic attempt to study the mind. Conscious awareness was broken down into basic categories: thoughts, images and sensations
Strength and weakness of WUNDTS methods
Strength: some aspects of Wundts methods would be classed as scientific today. For instance, Wundt recorded all introspection within a controlled lab environment. He also standardised his procedures. So Wundts research can be considered a forerunner to the later scientific approaches in psychology.
Weakness: can be considered unscientific by today’s standards. He relied on participants self-reporting their own ‘private’ mental processes. This data is subjective and participants may not have wanted to reveal some of their thoughts. Participants would also not have had exactly the same thoughts every time so establishing general principles would not have been possible, general laws are an aim of science. Therefore Wundts efforts to study the mind were naive and would not meet the criteria of scientific enquiry today.
What did Watson and early behaviourists argue
That introspection was subjective, it varied from person to person. A ‘scientific’ psychology should only study phenomena that can be observed and measured
What did the behaviourist approach lead to
Emergence of the scientific approach. Watson and Skinner brought the language and rigour of the natural sciences into psychology
How can the legacy of the experimental method still be observed today
Many modern psychologists rely on the experimental method. The cognitive approach investigates ‘private’ mental processes via lab tests.
The biological approach studies activity in the brain using scanning techniques like EEG and FMRI in controlled conditions.
What is the scientific method
An objective means of testing hypotheses in order to develop empirically based explanations/ theories
Strength and weakness of psychology using the scientific method
Strength: much of the research done in modern psychology is based on the method. It had the same aims as the natural sciences: to describe, understand, predict and control behaviour. Learning approach, cognitive approach and biological all rely on the use of the scientific method. Throughout the 20th century psychology has established itself as a scientific discipline.
Weakness: other approaches that do not use objective methods to study behaviour. Humanistic approach is anti-scientific and does not try to generate general laws of behaviour. Psychodynamic uses the case study method which is open to bias and no attempt is made to gather a representative sample of the population. For this reason, many claim that a scientific approach to study human thought and experience is not possible as it is important to take into account subjective experiences
What are the two learning approaches
Behaviourism
Social learning theory
What are the key features of the behaviourist approach
Observable and measurable behaviour. Lab experiments. Animals in research. Classical conditioning. Operant conditioning. Positive and negative reinforcement and punishment.
What is the behaviourist approach
A way of explaining behaviours in terms of what is observable and in terms of learning
Why was introspection rejected by behaviourists
As it’s concepts were vague and difficult to measure
Why do behaviourists rely on lab experiments
As they try to maintain more control and objectivity with their research than WUNDT
Why do behaviourists advocate the use of animals in research
Following Darwin, they suggested the processes that govern learning are the same in all species, so non-human animals can replace humans as experimental subjects
What is classical conditioning
Learning through association. Occurs when two stimuli are repeatedly paired together - an unconditioned stimulus and a neutral stimulus. The neutral stimulus eventually produces the same response that was first produced by the unconditioned stimulus alone
What did PAVLOV demonstrate
How dogs could be conditioned to salivate to the sound of a bell if that sound was repeatedly presented at the same time as the dogs were given food
What is operant conditioning
A form of learning in which behaviour is shaped and maintained by its consequences. Possible consequences include positive reinforcement, negative reinforcement or punishment
What did SKINNER suggest
That learning is an active process whereby humans and animals operate on their environment
What is positive reinforcement
A stimulus that increases the probability that a behaviour will be repeated because it is pleasurable
