Science & Psych Unit 1 Flashcards
Scientific method
Represents logic of inquiry, specific system of rules to be followed in solving problems and acquiring knowledge.
Objective observations
Made in a way that any person having normal perception and being in the same place at the same time arrive at the same observation.
Science has 4 objectives
- Descriptive: phenomenon must be described in detail
- Explanation: the cause of phenomenon must be explained
- Prediction: accurate predictions of future events can be made
- Control: Events might be controlled
Assumptions of science
- Realism: the world exists outside of our minds
- Rationality: the world can be understood by logic thinking
- Regularity: world follows same laws at all times and all places
- Discoverability: we can discover how the world works (possible to learn solutions to questions)
- Causality: all events have a cause
What is the belief that all events are caused?
Determinism
Cause and effect has 3 criteria that must be met
- Temporal precedence - Something that occurs prior to another thing (cause before event) ex: must eat ice cream before getting sick
- Co-variation of cause and effect - When cause is introduced the effect occurs. ex: you eat ice cream again and get sick
- Elimination of alternative explanations - No other possible explanation
Characteristics of science (POPEST)
- Progressive - science moves forward toward truth, adding more information continually
- Objective - MOST IMPORTANT, objective observation
- Parsimonious - we should use the simplest explanation possible to account for a given phenomenon
- Empirical - directly seen
- Self-correcting - new evidence corrects previous beliefs
- Tentative - never claims to have the whole truth
- Concerned with theory
What are the different ways of knowing behavior?
- Non-empirical methods - Authority & Logic
2. Empirical methods - Intuition & Science
Authority - definition and limitations
Authority - receiving answers/information from someone who is of authority
Limitation - it is often wrong
Logic - definition and limitations
Logic - based on reasoning
ex) “humans are animals, THEREFORE human behavior is..
The first 2 sentences are truth, and the 3rd is logic
Limitation - the logical answer can be valid but not true
Intuition - definition and limitations
Intuition - described as common sense (gut-feeling or hunches)
Limitations - standards differ from time to time and place to place according to attitudes and experiences of culture
- the only criteria it recognizes for judging truth is whether or not it works
Science - definition and limitations
Science - (SUPERIOR to all others) obtaining knowledge through objective observation
