Chapter 1 Flashcards
looking at psych today and attempting to show how it became that way
presentism
study of past for its own sake without attempting to relate past and present
Historicism
a spirit of the times
Zeitgeist
how individuals or events contributed ot changes in ideas/concepts over the years
Historical development approach
use whatever method best illuminates an aspect of the history
Eclectic approach
Who wore “Those who cannot remember the past are condemned to repeat it”
William James
Science is characterized as having two major components
what are they?
1) Empirical observation
2) Theory
Empiricism: :
The source of all knowledge is sensory observation. Therefore, true knowledge can only be derived from or validated only by sensory experiences
rationalism:
the validity or invalidity of certain propositions can be determined by carefully applying the rules of logic
how does science draw from both rationalism and empiricism
the direct observation of nature is important but this observation is often guided by theory
Scientific theories have two main functions * and must be testable
1) It organizes empirical observations
2) It acts as a guide for future observations
in general How a theory evolves
- If propositions are generated by a theory and those propositions are confirmed through experimentation. If they are not confirmed, then the theory loses strength
- If the theory has too many incorrect propositions the theory is then revised or abandoned
a scientific law
consistently observed relationships between two or more classes of empirical events
- By stressing lawfulness science is talking about things in general, not individual specific events
Two classes of scientific laws
Correlational Laws: describe how classes of events vary together in some systematic way
o Allow for prediction
Casual Laws: specific how events are causally related. One causes the other, one allows us to predict the other
o Allows for prediction and control
o More powerful than correlational laws
For science: The concept of public observation
- All scientific claims must be verifiable by any interested person. There is no secrete knowledge
The assumption of determinism
A determinist assumes that everything that occurs is a function of a finite of causes and that if all causes were known we could predict with certainty
- Since we are trying to discover lawful relationships using science, we assume that we are investigating is lawful
Determinism: the assumption that what is being studied can be understood in terms of causal laws
“ states that for everything that ever happens there are conditions such that, given them, nothing else could happen”
However, knowing all causes of an event is not necessary; the determinist simply assumes that they exist and that as more causes are known, predictions become more accurate.
How did Karl Popper disagree with the traditional view of science
- Disagreed that scientific activity starts with empirical observation
o Thought this implied ppl just wander around and attempt to explain what they’ve seen
o Thought that science actually started with a problem. The problem then determines what observations need to be made.
o Then you propose solutions to the problem (conjectures) and attempt to find fault in the solutions (refutations)
o Poppers three stages of the scientific method:
1) Problems
2) Theories (proposed solutions)
3) Criticisms
What causes scientific progress according to popper
a theory’s incorrect predictions
did popper believe that there was a theory that could last forever
Popper believed all scientific theories will eventually be found false and replaced with better ones.
Explain the correspondence of truth and Kuhn
Thomas Kuhn
There is a correspondence theory of truth before Kuhn. Ppl believed that science was guided in a non-biased way. Kuhn believed science to be a highly subjective experience
Through paradigms –> accepted –> normal science
Explain how Kuhn viewed science and his development of paradigms
Kuhn: Normal science is like puzzle solving. There are assured solutions, rules that limit acceptable solutions and steps to the solution. Kuhn didn’t see much creativity in puzzle solving or normal science.
2 sides of a paradigm:
- Positive: guarantees that certain phenomena are studied thoroughly,
- Negative: blinds researcher to other phenomena and potentially better explanations
Anomalies: what Kuhn called persistent observations that a currently accepted paradigm can’t explain
Development of paradigms: Preparadigmatic stage (prescientific) -Many competing viewpoints exist
Paradigmatic stage
-One viewpoint beats out others and becomes a paradigm. This is when it becomes a science and normal science by researches occurs.
Revolutionary stage
-When an existing paradigm is displaced by another which in turn generated it on normal science
