Science and history of science - Unit 1 Flashcards
Zeitgeist
The general mood or quality of a particular period of history. Shown by the beliefs common at the time-
the spirit of time
science
Is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence
empirical observatios
direct observations of nature
two components of science
- empirical observation
- theory
rationalism
mental operations or principles must be employed before knowledgee can be attained
empiricism
empiricist maintains that the source of all knowledge is sensory observations
scientific theories
science is the result of the combination of rationalism and empiricism
functions of scientific theories
- organizes empirical observations
- acts a sa guid for future observations
scientific law
consistently observed relationship betweem two or more classes of empirical events (when x occurs, y also tends to occur)
correlational laws
describe how classes of events vary together in some systematic way
causal laws
specify how events are causally related
assumptions of determinism
what is being studied can be understood in terms of causal laws is called determinism
Karl popper
disagreed that scientific activity starts with empirical observations
principles of falsifiability
a scientific theory must be refutable
falsiafiability test
for the hypothesis to be scientific, there must be a way tot est it and potentially demonstrate that its false (ex. earth is flat?)
Thomas Kunn
he believed that the scientific method guaranteed objecitivity = paradigms (pattern or model, highly subjective)
+ forces scientists to investigate some part of nature in a detail and depth
- blind scientisitcs to other phenomena
3 stages of scientific development
- preparadigmatic stage [still developing different point of view exists regarding subject matter]
- paradigmatic stage [discipline becomes a science, paradigm]
- revolutionary stage [existing paradigm is displaced by another paradigm]
normal science
when a paradigm is accepted the activities of those accpeting become matter of exploring implications
3 ways to understand scientific activity
- problems
- theories
- criticism
multiparadigmatic disciplice
coexisting paradigms in psychology (ex. behavioristics, cognitive, psychobiological, psychoanalytic, developmental, humanistic)
determinism
The assumption that behavior is caused by heredity and environment
biological determinism
emphasizes the importance of physiological conditions or genetic predispostions in the explanation of behavior
environemntal determism
stresses importance of environemntal stimuli
sociocultural determism
emphasizes cultural or societal rules, regulations, customs, and beliefs that govern human behavior
