chapter 2 Flashcards
falsifiability
the ability for a statement/theory to be shown to be false
Hawthorne effect
the fact that people will modify their behavior simply because they are being observed
(human and non-human)
Bandura’s famous bobo doll study
demonstrated that children are able to learn social behavior such as aggression through the process of observational learning, through watching the behavior of another person.
opinion
personal judgment which may not be accurate
fact
observable reality
Deductive reasoning
start big with general ideas then move to specifics
The scientific method
stating the question, offering a theory and then constructing rigorous laboratory or field experiments to test the hypothesis
inductive reasoning
start small with specific and build up with big picture reasoning
Operationalized
developing precise definitions of variables in the study
Experimenter bias
the unintentional influence of the experimenter’s expectations, beliefs, or preconceived notions on the outcome of a study or research experiment.
single blind
A type of clinical trial in which only the researcher doing the study knows which treatment or intervention the participant is receiving until the trial is over.
Double blind
A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over.
Placebo effect
when a person’s physical or mental health appears to improve after taking a placebo or ‘dummy’ treatment
archival research
method of research using past records or data sets to answer various research questions, or to search for interesting patterns or relationships
attrition
reduction in number of research participants as some drop out of the study over time
cause-and-effect relationship
changes in one variable cause the changes in the other variable; can be determined only through an experimental research design
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
deception
purposely misleading experiment participants in order to maintain the integrity of the experiment
