Midterm Vocab Flashcards
behaviorism
focus on observing and controlling behavior
biopsychology
study of how biology influences behavior
cognitive psychology
study of cognitions, or thoughts, and their relationship to experiences and actions
empirical method
method for acquiring knowledge based on observation, including experimentation, rather than a method based only on forms of logical argument or previous authorities
functionalism
focused on how mental activities helped an organism adapt to its environment
humanism
perspective within psychology that emphasizes the potential for good that is innate to all humans
introspection
process by which someone examines their own conscious experience in an attempt to break it into its component parts
psychoanalytic theory
focus on the role of the unconscious in affecting conscious behavior
psychology
scientific study of the mind and behavior
structuralism
understanding the conscious experience through introspection
clinical or case study
observational research study focusing on one or a few people
confirmation bias
tendency to ignore evidence that disproves ideas or beliefs
confounding variable
unanticipated outside factor that affects both variables of interest, often giving the false impression that changes in one variable causes changes in the other variable, when, in actuality, the outside factor causes changes in both variables
control group
serves as a basis for comparison and controls for chance factors that might influence the results of the study—by holding such factors constant across groups so that the experimental manipulation is the only difference between groups
correlation
relationship between two or more variables; when two variables are correlated, one variable changes as the other does
correlation coefficient
number from -1 to +1, indicating the strength and direction of the relationship between variables, and usually represented by r
cross-sectional research
compares multiple segments of a population at a single time
debriefing
when an experiment involved deception, participants are told complete and truthful information about the experiment at its conclusion
dependent variable
variable that the researcher measures to see how much effect the independent variable had
double-blind study
experiment in which both the researchers and the participants are blind to group assignments
empirical
grounded in objective, tangible evidence that can be observed time and time again, regardless of who is observing
experimental group
group designed to answer the research question; experimental manipulation is the only difference between the experimental and control groups, so any differences between the two are due to experimental manipulation rather than chance
hypothesis
(plural: hypotheses) tentative and testable statement about the relationship between two or more variables
illusory correlation
seeing relationships between two things when in reality no such relationship exists
independent variable
variable that is influenced or controlled by the experimenter; in a sound experimental study, the independent variable is the only important difference between the experimental and control group
inductive reasoning
conclusions are drawn from observations
longitudinal research
studies in which the same group of individuals is surveyed or measured repeatedly over an extended period of time
naturalistic observation
observation of behavior in its natural setting
negative correlation
two variables change in different directions, with one becoming larger as the other becomes smaller; a negative correlation is not the same thing as no correlation
operational definition
description of what actions and operations will be used to measure the dependent variables and manipulate the independent variables
population
overall group of individuals that the researchers are interested in
positive correlation
two variables change in the same direction, both becoming either larger or smaller
random assignment
method of experimental group assignment in which all participants have an equal chance of being assigned to either group
random sample
subset of a larger population in which every member of the population has an equal chance of being selected
reliability
consistency and reproducibility of a given result
replicate
repeating an experiment using different samples to determine the research’s reliability
sample
subset of individuals selected from the larger population
statistical analysis
determines how likely any difference between experimental groups is due to chance
survey
list of questions to be answered by research participants—given as paper-and-pencil questionnaires, administered electronically, or conducted verbally—allowing researchers to collect data from a large number of people
