Unit 1 AP Psychology

thinking that does not blindly accept arguments and conclusions. Rather, it examines assumptions, appraises the source, discerns hidden biases, evaluates evidence, and assesses conclusions.

the idea that knowledge comes from experience, and that observation and experimentation enable scientific knowledge

an early school of thought promoted by Wundt and Titchener; used introspection to reveal the structure of the human mind.

the process of looking inward in an attempt to directly observe one's own psychological processes.

an 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.

the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most psychologists today agree with (1) but not with (2).

humanistic psychology a 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).

the science of behavior and mental processes.

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.

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.

the study of the evolution of behavior and the mind, using principles of natural selection.

the study of the relative power and limits of genetic and environmental influences on behavior.

the enduring behaviors, ideas, attitudes, values, and traditions shared by a group of people and transmitted from one generation to the next.

the scientific study of human flourishing, with the goals of discovering and promoting strengths and virtues that help individuals and communities to thrive.

an integrated approach that incorporates biological, psychological, and social-cultural viewpoints.

the scientific study of observable behavior, and its explanation by principles of learning.

the scientific study of the links between biological (genetic, neural, hormonal) and psychological processes. (Some biological psychologists call themselves behavioral neuroscientists, neuropsychologists, behavior geneticists, physiological psychologists, or biopsychologists.)

a branch of psychology that studies how unconscious drives and conflicts influence behavior and uses that information to treat people with psychological disorders.

the study of how situations and cultures affect our behavior and thinking.

enhanced memory after retrieving, rather than simply rereading, information. Also sometimes referred to as a retrieval practice effect or test-enhanced learning.

a study method incorporating five steps: Survey, Question, Read, Retrieve, Review.

the scientific study of the measurement of human abilities, attitudes, and traits.

pure science that aims to increase the scientific knowledge base.

a branch of psychology that studies physical, cognitive, and social change throughout the life span.

the study of how psychological processes affect and can enhance teaching and learning.

the study of individuals' characteristic patterns of thinking, feeling, and acting.

the scientific study of how we think about, influence, and relate to one another.

scientific study that aims to solve practical problems.

the application of psychological concepts and methods to optimizing human behavior in workplaces.

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.

a branch of psychology that assists people with problems in living (often related to school, work, or marriage) and in achieving greater well-being.

a branch of psychology that studies, assesses, and treats people with psychological disorders.

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.

a branch of psychology that studies how people interact with their social environments and how social institutions affect individuals and groups.

the tendency to believe, after learning an outcome, that one would have foreseen it. (Also known as the I-knew-it-all-along phenomenon.)

an explanation using an integrated set of principles that organizes observations and predicts behaviors or events.

a testable prediction, often implied by a theory.

a carefully worded statement of the exact procedures (operations) used in a research study. For example, human intelligence may be operationally defined as what an intelligence test measures.

repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding can be reproduced.

a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles.

a descriptive technique of observing and recording behavior in naturally occurring situations without trying to manipulate or control the situation.

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.

a flawed sampling process that produces an unrepresentative sample.

all those in a group being studied, from which samples may be drawn. (Note: Except for national studies, this does not refer to a country's whole population.)

a sample that fairly represents a population because each member has an equal chance of inclusion.

a measure of the extent to which two factors vary together, and thus of how well either factor predicts the other.

a statistical index of the relationship between two things (from −1.00 to +1.00).

anything that can vary and is feasible and ethical to measure.

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 (little scatter indicates high correlation).

perceiving a relationship where none exists, or perceiving a stronger-than-actual relationship.

the tendency for extreme or unusual scores or events to fall back (regress) toward the average.

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). By random assignment of participants, the experimenter aims to control other relevant factors.

in an experiment, the group exposed to the treatment, that is, to one version of the independent variable.

in an experiment, the group not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.

assigning participants to experimental and control groups by chance, thus minimizing preexisting differences between the different groups.

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.

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.

in an experiment, the factor that is manipulated; the variable whose effect is being studied.

a factor other than the factor being studied that might influence a study's results.

in an experiment, the outcome that is measured; the variable that may change when the independent variable is manipulated.

the extent to which a test or experiment measures or predicts what it is supposed to. (See also content validity and predictive validity.)

giving potential participants enough information about a study to enable them to choose whether they wish to participate.

the postexperimental explanation of a study, including its purpose and any deceptions, to its participants.

numerical data used to measure and describe characteristics of groups. Includes measures of central tendency and measures of variation.

a bar graph depicting a frequency distribution.

the most frequently occurring score(s) in a distribution.

the arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores.

the middle score in a distribution; half the scores are above it and half are below it.

(normal distribution) a symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean (about 68 percent fall within one standard deviation of it) and fewer and fewer near the extremes.

numerical data that allow one to generalize—to infer from sample data the probability of something being true of a population.

a statistical statement of how likely it is that an obtained result occurred by chance.

first female president of the APA (1905); a student of William James; denied the PhD she earned from Harvard because of her sex (later, posthumously, it was granted to her)

English natural scientist who formulated a theory of evolution by natural selection (1809-1882)

A reformer and pioneer in the movement to treat the insane as mentally ill, beginning in the 1820's, she was responsible for improving conditions in jails, poorhouses and insane asylums throughout the U.S. and Canada. She succeeded in persuading many states to assume responsibility for the care of the mentally ill. She served as the Superintendant of Nurses for the Union Army during the Civil War.

Austrian physician whose work focused on the unconscious causes of behavior and personality formation; founded psychoanalysis.

the view that psychology should be an objective science that studies behavior without reference to mental processes

an organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes.

An approach to psychology centered on evolutionary ideas such as adaptation, reproduction, and natural selection as the basis for explaining specific human behaviors.

An approach to psychology emphasizing the mental processes involved in knowing: how we direct our attention, perceive, remember, think, and solve problems.

Social interaction and the cultural determinants of behavior and mental processes

An area of development such as fine and gross motor skills, cognitive abilities, self-help capabilities, and social and communication skills.

(I/O) the application of psychological concepts and methods to optimizing human behavior in workplaces

change in variables that are associated with the relationship of an individual to others

a research method that describes and predicts how variables are naturally related in the real world, without any attempt by the researcher to alter them or assign causation between them

the most popular technique for gathering primary data, in which a researcher interacts with people to obtain facts, opinions, and attitudes

A research method that studies the same participants multiple times over a period of time
