hypothesis
explicit, testable prediction about the conditions under which an event will occur
Proposal of a theory
an organized set of principles used to explain observed phenomena (more advanced step in process after hypotheses)
Basic research
research whose goal is to increase understanding of human behavior, often by testing hypotheses based on a theory
Applied research
research whose goal is to make applications to the world and contribute to the solution of social problems
Conceptual variables
variables that are in an abstract, general form when a researcher first develops a hypothesis (ex: prejudice, conformity, attraction, love, group pressure, social anxiety)
Operational definition
the specific procedures for manipulating or measuring a conceptual variable
Confound
a factor other than the independent variable that varies between the conditions of an experiment, thereby calling into question what caused any effects on the dependent variable
Construct validity
the extent to which the measures used in a study measure the conceptual variables they were designed to measure and the manipulations in an experiment manipulate the conceptual variables they were designed to manipulate
External validity
the degree to which there can be reasonable confidence that the results of a study would be obtained for other people in other situations (generalization, who can this conclusion apply to?)
Internal validity
Replication
repeating a research study to see if the results are similar to those found in the original study
Subject variables
a variable that characterizes preexisting differences among the participants in a study (ie age, gender, personality traits, ethnicity)
Self-report
a widely used measurement technique in which participants disclose their thoughts, feelings, desires, and actions through individual questions or a set of questions that measure a single conceptual variable
limitations to self-report
5
not always accurate, can be misleading, affected by the way questions are asked or worded, peoples’ memories are prone to error
Bogus pipeline technique
a procedure in which participants are (falsely) led to believe that their responses will be verified by an infallible lie detector - bogus pipeline is in fact bogus but belief in its power discourages people from lying
Interval-contingent self-reports
respondents report their experiences at regular intervals, usually once a day
Signal-contingent self-reports
respondents report their experiences as soon as possible after being signaled to do so, usually by means of a text message or app
Event-contingent self-reports
respondents report on a designated set of events as soon as possible after such events have occurred
Observation
method to measure variables by observing people’s actions
Interrater reliability
level of agreement among multiple observers of the same behavior, only when different observers agree can the data be trusted
advantages of observational methods
avoid faulty recollections and distorted interpretations of our own behavior
limitations of observational methods
if we know we’re being observed, we might act differently than usual, scientists have to figure out subtle ways to observe
Eye-tracking technology
used to measure exactly where and for how long participants look at particular parts of a stimulus
Descriptive research
recording how frequently or how typically people think, feel, or behave in particular ways - often includes observing people, studying records of past events and behaviors, and surveying people
