Features of Science Flashcards
Key features:
- Objectivity
- Emperical Method
- Replicability
- Control
- Hypothesis testing
Objectivity
(Study) not affected by the expectations of the researcher
Emperical Method
Information is gained through direct observation/experiment. It’s important as it allows to test the validity of a theory through direct testing
Replicability
Research should be able to be repeated
* If the outcome is the same this affirms the truth of the original results
* Its important for scientists to record their procedures carefully so someone else can repeat them exactly and verify the original results
* Unrepeatable results may imply flaws or lack of control
Control
Research is carried out in controlled conditions
Facts are accquired through controlled research
Hypothesis testing
For research to be considered scientific, it must be able to generate testable expectations
Different views on psychology as a science:
To what extent is scientific research good?
* Science takes the nomothetic approach, looking to make generalisations about people and looking to find similarities (wider population)
* Some psychologists oppose this and prefer the idiographic approach which means studying people as individual cases, without comparing them to others and making generalisations about them
Thomas Kuhn Theory: Paradigms of science
Kuhn put in a theory that there are 3 stages of science:
1. Prescience
2. Normal Science
3. Revolutionary Science
Prescience
A variety of theories that attempt to explain a phenomenon, but there is no generally accepted theory/paradigm
Normal Science
A theory has emerged and is generally accepted/dominated the science
Over a period of time, however, evidence appears that contradicts this dominant paradigm
Revolutionary Science
Evidence against existing paradigm continues to grow- Paradigm is questioned
There is a division and difference in opinion between scientists
Alternative theories are put forward, until eventually a new theory is accepted- ‘paradigm shift’
Psychology IS a science…
- Psychology has the same aims as the natural science- to describe, understand, predict and control behaviour
- Behaviourist, cognitive and biological approach use scientific methods e.g lab studies to investigate in a controlled, unbiased way
- Suggests taht throughout the 20th century + beyond, psychology has established itself as a scientific discipline
Psychology ISNT a science…
- A limitation with psychology is that not all approaches use objective methods
- The humanistic approach rejects the scientific approach, preferring to focus on individual + subjective experience
- The psychodynamic approach makes use of the case study method which does not use representative sample
