applied research - Research designed to enlarge the understanding of naturally occurring events
and to find solutions to practical problems. (p. 29)
basic research - Research designed to increase the understanding of human behaviour, often by
testing hypotheses based on a theory. (p. 29)
confederate - Accomplice of an experimenter who, in dealing with the real participants in an
experiment, acts as if he or she is also a participant. (p. 45)
construct validity - The extent to which the measures used in a study measure the variables they
were designed to measure and the manipulations in an experiment manipulate the variables they
were designed to manipulate. (p. 30)
correlation coefficient - A statistical measure of the strength and direction of the association
between two variables. (p. 37)
correlational research - Research designed to measure the association between variables that
are not manipulated by the researcher. (p. 37)
debriefing - A disclosure, made to participants after research procedures are completed, in
which the researcher explains the purpose of the research, attempts to resolve any negative
feelings, and emphasizes the scientific contribution made by the participants’ involvement. (p.
49)
deception - In the context of research, a method that provides false information to participants.
(p. 45)
dependent variable - In an experiment, a factor that experimenters measure to see if it is
affected by the independent variable. (p. 42)
experiment - A form of research that can demonstrate causal relationships because the
experimenter has control over the events that occur and participants are randomly assigned to
conditions. (p. 40)
experimental realism - The degree to which experimental procedures are involving to
participants and lead them to behave naturally and spontaneously. (p. 45)
experimenter expectancy effects - The effects produced when an experimenter’s expectations
about the results of an experiment affect his or her behaviour toward a participant and thereby
influence the participant’s responses. (p. 44)
external validity - The degree to which there can be reasonable confidence that the results of a
study would be obtained for other people and in other situations. (p. 44)
hypothesis - A testable prediction about the conditions under which an event will occur. (p. 28)
