Studied by 15 people
Empirical Methods
Approaches to inquiry that are tied to actual measurement and observation.
Ethics
Professional guidelines that offer researchers a template for making decisions that protect research participants from potential harm and that help steer scientists away from conflicts of interest or other situation that might compromise the integrity of research.
Hypotheses
A logical idea that can be tested.
Systematic observation
The careful observation of the natural world with the aim of better understanding it. Observations provide the basic data that allow scientists to track, tally, or otherwise organize information about the natural world.
Theories
Groups of closely related phenomena or observations.
Anecdotal evidence
A piece of biased evidence, usually drawn from personal experience, used to support a conclusion that may or may not be correct.
Causality
In research, the determination that one variable causesâis responsible forâan effect.
Correlation
In statistics, the measure of relatedness of two or more variables.
Data (also called observations)
In research, information systematically collected for analysis and interpretation.
Deductive reasoning
A form of reasoning in which a given premise determines the interpretation of specific observations (e.g., All birds have feathers; since a duck is a bird, it has feathers).
Distribution
In statistics, the relative frequency that a particular value occurs for each possible value of a given variable.
Empirical
Concerned with observation and/or the ability to verify a claim.
Fact
Objective information about the world.
Falsify
In science, the ability of a claim to be tested andâpossiblyârefuted; a defining feature of science.
Generalize
In research, the degree to which one can extend conclusions drawn from the findings of a study to other groups or situations not included in the study.
Hypothesis
A tentative explanation that is subject to testing.
Induction
To draw general conclusions from specific observations.
Inductive reasoning
A form of reasoning in which a general conclusion is inferred from a set of observations (e. g., noting that âthe driver in that car was texting; he just cut me off then ran a red light!â (a specific observation), which leads to the general conclusion that texting while driving is dangerous).
Levels of analysis
In science, there are complementary understandings and explanations of phenomena.
Null-hypothesis significance testing (NHST)
In statistics, a test created to determine the chances that an alternative hypothesis would produce a result as extreme as the one observed if the null hypothesis were actually true.
Objective
Being free of personal bias.
Population
In research, all the people belonging to a particular group (e.g., the population of left handed people).
Probability
A measure of the degree of certainty of the occurrence of an event.
Probability values
In statistics, the established threshold for determining whether a given value occurs by chance.
Pseudoscience
Beliefs or practices that are presented as being scientific, or which are mistaken for being scientific, but which are not scientific (e.g., astrology, the use of celestial bodies to make predictions about human behaviors, and which presents itself as founded in astronomy, the actual scientific study of celestial objects. Astrology is a pseudoscience unable to be falsified, whereas astronomy is a legitimate scientific discipline).
Representative
In research, the degree to which a sample is a typical example of the population from which it is drawn.
Sample
In research, a number of people selected from a population to serve as an example of that population.
Scientific theory
An explanation for observed phenomena that is empirically well-supported, consistent, and fruitful (predictive).
Type 1 error
In statistics, the error of rejecting the null hypothesis when it is true.
Type 2 error
In statistics, the error of failing to reject the null hypothesis when it is false.
Value
Belief about the way things should be.
Behaviourism
The study of behaviour.
Cognitive Psychology
The study of mental processes.
Consciousness
Awareness of ourselves and our environment.
Empiricism
The belief that knowledge comes from experience.
Eugenics
The practice of selective breeding to promote desired traits.
Flashbulb memory
A highly detailed and vivid memory of an emotionally significant event.
Functionalism
A school of American psychology that focused on the utility of consciousness.
Gestalt psychology
An attempt to study the unity of experience.
Individual differences
Ways in which people differ in terms of their behavior, emotion, cognition, and development.
Introspection
A method of focusing on internal processes.
Neural impulse
An electro-chemical signal that enables neurons to communicate.
Practitioner-Scholar Model
A model of training of professional psychologists that emphasizes clinical practice.
Psychophysics
Study of the relationships between physical stimuli and the perception of those stimuli.
Realism
A point of view that emphasizes the importance of the senses in providing knowledge of the external world.
Scientist-practitioner model
A model of training of professional psychologists that emphasizes the development of both research and clinical skills.
Structuralism
A school of American psychology that sought to describe the elements of conscious experience.
Tip-of-the-tongue phenomenon
The inability to pull a word from memory even though there is the sensation that that word is available.
