Critical Thinking
thinking that does not blindly accept arguments and conclusions. Rather, it examines assumptions, discerns hidden values, evaluates evidence, and assesses conclusions.
Empiricism
the idea that knowledge comes from experience, and that observation and experimentation enable scientific knowledge
Structuralism
early school of thought promoted by Wundt and Titchener; used introspection to reveal the structure of the human mind
Introspection
the process of looking inward in an attempt to directly observe one's own psychological processes
Functionalism
early school of thought promoted by James and influenced by Darwin; explored how mental and behavioral processes function- how they enable the organism to adapt, survive, and flourish
Behaviorism
the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2).
Humanistic Psychology
historically significant perspective that emphasized human growth potential
Cognitive Psychology
the study of mental processes, such as occur when we perceive, learn, remember, think, communicate, and solve problems.
Cognitive Neuroscience
the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language)
Psychology
the scientific study of behavior and mental processes
Nature-Nurture Issue
the longstanding controversy over the relative contributions that genes and experience make to the development of psychological traits and behaviors. Today's science sees traits and behaviors arising from the interaction of nature and nurture
Natural Selection
the principle that inherited traits that better enable an organism to survive and reproduce in a particular environment will (in competition with other trait variations) most likely be passed on to succeeding generations
Evolutionary Psychology
the study of the evolution of behavior and the mind, using principles of natural selection
Behavior Genetics
the study of the relative power and limits of genetic and environmental influences on behavior
Culture
the enduring behaviors, ideas, attitudes, values, and traditions shared by a group of people and transmitted from one generation to the next
Positive Psychology
the scientific study of human flourishing, with the goals of discovering and promoting strengths and virtues that help individuals and communities to thrive
Biopsychosocial Approach
an integrated approach that incorporates biological, psychological, and social-cultural viewpoints
Behavioral Psychology
study of observable behavior, and its explanation by principles of learning
Biological Psychology
the scientific study of the links between biological (genetic, neural, hormonal) and psychological processes
Psychodynamic Psychology
a branch of psychology that studies how unconscious drives and conflicts influence behavior, and uses that information to treat people with psychological disorders
Social-Cultural Psychology
the study of how situations and cultures affect our behavior and thinking
Testing Effect
enhanced memory after retrieving, rather than simply rereading, information
SQ3R
a study method incorporating five steps: Survey, Question, Read, Retrieve, Review
Psychometrics
the scientific study of the measurement of human abilities, attitudes, and traits
Basic Research
pure science that aims to increase the scientific knowledge base
Developmental Psychology
a branch of psychology that studies physical, cognitive, and social change throughout the life span
Educational Psychology
the study of how psychological processes affect and can enhance teaching and learning
Personality Psychology
the study of individuals' characteristics patterns of thinking, feeling, and acting
Social Psychology
the scientific study of how we think about, influence, and relate to one another
Applied Research
scientific study that aims to solve practical problems
Industrial-Organizational (I/O) Psychology
the application of psychological concepts and methods to optimizing human behavior in workplaces
Human Factors Psychology
a field of psychology allied with I/O psychology that explores how people and machines interact and how machines and physical environments can be made safe and easy to use
Counseling Psychology
a branch of psychology that assists people with problems in living (often related to school, work, or marriage) and in achieving greater well-being
Clinical Psychology
a branch of psychology that studies, assesses, and treats people with psychological disorders
Psychiatry
a branch of medicine dealing with psychological disorders; practiced by physicians who are licensed to provide medical (for example, drug) treatments as well as psychological therapy
Community Psychology
a branch of psychology that studies how people interact with their social environments and how social institutions affect individuals and groups
Hindsight Bias
the tendency to believe, after learning an outcome, that one would have foreseen it
Theory
an explanation using an integrated set of principles that organizes observations and predicts behaviors or events
Hypothesis
A testable prediction, often implied by a theory
Operational Definition
a carefully worded statement of the exact procedures (operations) used in a research study
Replication
repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding can be reproduced
Case Study
a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles
Naturalistic Observation
a descriptive technique of observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation
Survey
a descriptive technique for obtaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group
Sampling Bias
a flawed sampling process that produces an unrepresentative sample
Population
all those in a group being studied, from which samples may be drawn
Random Sample
a sample that fairly represents a population because each member has an equal chance of inclusion
Correlation
A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other.
Correlation Coefficient
a statistical index of the relationship between two things (from -1.00 to +1.00)
Variable
anything that can vary and is feasible and ethical to measure
Scatterplot
a graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables. The amount of scatter suggests the strength of the correlation.
Illusory Correlation
perceiving a relationship where none exists, or perceiving a stronger-than-actual relationship
Regression towards the mean
the tendency for extreme or unusual scores to fall back (regress) toward the average.
Experiment
A research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable)
Experimental Group
In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable.
Control Group
In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.
Random Assignment
assigning participants to experimental and control conditions by chance, thus minimizing preexisting differences between those assigned to the different groups
Double-blind Procedure
an experimental procedure in which both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo. Commonly used in drug-evaluation studies.
Placebo Effect
experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent.
Independent Variable
in an experiment, the factor that is manipulated; the variable whose effect is being studied
Confounding Variable
a factor other than the factor being studied that might influence a study's result
Dependent Variable
in an experiment, the outcome that is measured; the variable that may change when the independent variable is manipulated
Validity
the extent to which a test measures or predicts what it is supposed to
Informed Consent
giving potential participants enough information about a study to enable them to choose whether they wish to participate
Debriefing
the post-experimental explanation of a study, including its purpose and any deceptions, to its participants
Descriptive Statistics
numerical data used to measure and describe characteristics of groups. Includes measures of central tendency and measures of variation.
Histogram
a bar graph depicting a frequency distribution
Mode
the most frequently occurring score(s) in a distribution
Mean
the arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores
Median
the middle score in a distribution; half the scores are above it and half are below it
Skewed Distribution
a representation of scores that lack symmetry around their average value
Range
the difference between the highest and lowest scores in a distribution
Standard Deviation
a computed measure of how much scores vary around the mean score
Normal Curve
the symmetrical bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean, and fewer and fewer scores lie near the extremes.
Inferential Statistics
numerical data that allow one to generalize- to infer from sample data the probability of something being true of a population
Statistical Significance
a statistical statement of how likely it is that an obtained result occurred by chance
