M1: Pitfalls in Research Flashcards
Laboratory setting or the knowledge that an experiment is underway may alter the behavior patterns.
DEMAND CHARACTERISTICS
participants spontaneously form ________ or _______ about the experiment’s purpose and behave or respond in a way that will satisfy the purpose
hypotheses or assumptions
________ named after the Western Electric Company plant where it was observed.
HAWTHORNE EFFECT
influences the outcome accidentally by providing participants with slight cues as to the experimenter’s expectations.
EXPERIMENTER EFFECT
an experimenter might not be aware that he or she nods approvingly when a correct response is given and frowns after errors.
EXPERIMENTER EFFECT
The gender, race and ethnicity of the experimenter are also potential __________.
experimenter effects
Experimenter characteristics are more likely to bias the results of an experiment in research that focuses on issues related to these characteristics.
EXPERIMENTER EFFECT
TRUE or FALSE
The best way to eliminate experimenter effect is to hide the experimental condition from the experimenter on the premise that experimenters cannot communicate what they do not know.
TRUE
The term is called _________ where neither the experimenter nor the research participant knows which subjects are in which treatment conditions.
DOUBLE-BLIND EXPERIMENT
______ and other equipment may aid to prevent human errors.
Computers
The entire experiment is conducted by a computer.
AUTOMATION OF EXPERIMENTS
The experimenter appears at the end of the data collection to debrief the participants, giving the aims of the study and explaining how the subject has helped advance science.
AUTOMATION OF EXPERIMENTS
errors in design
