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

New cards
2

Functionalism

early school of though promoted by James and influenced by Darwin; explored how mental and behavioral processes function-how they enable to organism to adapt, survive, and flourish

New cards
3

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).

New cards
4

Humanistic Psychology

historically significant perspective that emphasized human growth potential

New cards
5

Cognitive Neuroscience

the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language).

New cards
6

Psychology

the science of behavior and mental processes

New cards
7

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

New cards
8

Natural Selection

the principle that among the range of inherited trait variations, those contribution to reproduction and survival will most likely be passed on to succeeding generations

New cards
9

Evolutionary Psychology

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

New cards
10

Behavior Genetics

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

New cards
11

Culture

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

New cards
12

Positive Psychology

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

the differing complementary views, from biological to psychological to social-cultural, for analyzing any given phenomenon

New cards
14

Biopsychosocial Approach

an integrated approach that incorporates biological, psychological , and social-cultural levels of analysis

New cards
15

Basic Research

pure science that aims to increase the scientific knowledge base

New cards
16

Applied Research

scientific study that aims to solve practical problems

New cards
17

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

New cards

Community Psychology

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

New cards
21

Testing Effect

enhanced memory after retrieving, rather than simply rereading, information

New cards
22

SQ3R

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

New cards
23

Intuition

an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning

New cards
24

Hindsight Bias

the tendency to believe, after learning an outcome, that one would have foreseen it

New cards
25

Theory

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

New cards
26

Hypothesis

a testable prediction, often implied by a theory

New cards
27

Operational Definition

a carefully worded statement of the exact procedures (operations) used in a research study

New cards
28

Replication

repeating the essence of a research study, usually with different participants in different situations, to see whether the basic findings extends to other participants and circumstances

New cards
29

Case Study

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

New cards
30

Naturalistic Observation

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

New cards
31

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

New cards
32

Population

all those in a group being studied from which samples may be drawn

New cards
33

Random Sample

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

New cards
34

Correlation

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

New cards
35

Correlation Coefficient

a statistical index of the relationship between two things (from -1 to +1)

New cards
36

Scatterplot

a graphed cluster of dots, each of which represent the values of two variables. The slope of the points suggest the direction of the relationship between the two variables. The amount of the scatter suggests the strength of the correlation

New cards
37

Regression toward the mean

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

New cards
38

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)

New cards
39

Experimental Group

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

New cards
40

Control Group

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

New cards
41

Random Assignment

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

New cards
42

Double-Blind Procedure

an experimental procedure in which both of the research participants and the research staff are blind about whether the research participants have received the treatment or a placebo

New cards
43

Placebo

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

New cards
44

Independent Variable

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

New cards
45

Confounding Variable

in an experiment, a factor other than the independent variable that might produce an effect

New cards
46

Dependent Variable

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

New cards
47

Informed Consent

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

New cards
48

Debriefing

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

New cards
49

Mode

the most frequently occurring score(s) in a distribution

New cards
50

Mean

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

New cards
51

Median

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

New cards
52

Range

the difference between the highest and lowest scores in a distribution

New cards
53

Standard Deviation

a computed measure of how much scores vary around the mean score

New cards
54

Normal Curve

a symmetrical, bell-shaped curve that describes the distribution of many types of data

New cards
55

Statistical Significance

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