What is science Flashcards
Science
A set of methods used to collect information about phenomena in a particular area of interest
–> science is a diverse activity involving a diverse group of people doing a wide rande of things
Psychology as a science
the science of behaviour and mental processes
Basic research
Goal is to acquire general information about a phenomenon with little emphasis on application to real-world examples
Applied research
Goal to generate information that can be applied directly to a real-world problem
Confirmation bias
The human tendency to seek out information that confirms what is already believed
Analogy of Caldini (1994)
Science is like a hunting trip
- scouting the reasearch field
- trapping - finding factors to study and doing so
Protoscience
Science on the edge of current scientific understanding
Non science
Applies systematic techniques to the acquisition of information, but lacks empirical tests
Pseudoscience
A set of ideas based on theories put forth as scientific when they are not scientific
Scientific explanations need to be
- Empirical
- Rational
- Testable
- Parsimonious
- General
- Tentative/Falsifiable
- Rigorously evaluated
Common-sense Explanations
Explanations based on our own sens of what is true about thhe world around us
Belief based explanations
Explanations based on beliefs from individuals or groups (trough indoctrination, upbringing or personal need)
Method of Authority
using expert sources (books or people) you consider authoritative –> useful in the early stages of acquiring knowledge
The rational method
depends on logical reasoning
–> Logically deduced conclusions from self-evident truths
The scientific Method
Four cyclical steps to the solution of a scientific problem:
- observing a phenomenon
- formulating tentative explanations (hypothesis)
- further observing and experimenting
- refining and retesting explanations
Deductive reasoning
Moves from generalized premise that is known to be true, to a true specific conclusion
–> top down reasoning
Inductive reasoning
Moves from specific instances to a generalized conclusion
–> bottom up reasoning
Steps of the research process
- developing a research idea and hypothesis
- choosing a research design
- choosing subjects
- deciding on what to observe and appropriate measures
- conducting your study
- analyzing your results
- reporting the results
- starting the whole process over again
Theory
a plausible or scientifically acceptable, well substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena and predict the characteristics of as yet unobserved phenomena
Hypothesis
tentative explanation for an observation, phenomenon or scientific problem that can be tested by further investigation. Must be posed in a form that allows to be rejected
roles of theories in science
-understanding
prediction
-organizing and interpreting research results
-generating research
why use Deception in research
used because in some cases full disclosure of the study would invalidate the findings
Different types of deception
- active deception
- passive deception
- -> intentional deception - nonintentional deception - not fully disclosing all information
When is it allowed to use deception
○ Study´s scientific, educational, or applied value
○ No harm comes to the participant
○ No other available options
○ Participants are provided with an explanation for deception asap
reputational spillover effect
effect caused by deception in research, when the participant develops a negative attitude towards research and psychology as a whole
Debriefing
Technique used to inform participants of the deception asap
–> Goal: to restore the participants trust and self-esteem and to make them less suspicious of other research
examples of non ethical research
- John Watson & little Albert
- -> Study to determine if emotional responses could be learned - Fear or Anger by Albert Ax
- -> Each emotion unique physiological response or common physiological response
APA ethical guidelines
American psychological association
–> specifies ethical responsibilities of psychologists and code of conduct
What constitutes Research Misconduct
- Data fabrication - making up data or results and reporting on them
- Falsification - manipulating research materials, equipment or processes or changing/omitting data
- Plagiarism - appropriation of another person´s ideas, processes, results or words without giving apporpriate credit
How to make science ethical
- grant review process
- peer review
- Replication of your results
