Psych Research Flashcards
(43 cards)
archival Research
method of research using past records or data sets
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
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
outside factor that affects both variables of interest
(gives the false impression of a cause-and-effect relationship between two variable, when the
outside factor is causing changes in both variables)
control group
group that does is not manipulated and serves for comparison (the independent variable or effect)
correlation
when two or more variables have a relationship; one variable
changes as the other does
correlation coefficient
number on a scale from 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
deception
when participants are mislead in order to maintain the integrity of the experiment. after the experiment, they are debriefed.
deductive reasoning
predicting results based on an idea
dependent variable
variable that the researcher measures to see how much effect the independent variable had (control group, or the effect)
double-blind study
experiment in which both the researchers and the participants are blind to group
assignments
empirical
grounded in tangible evidence that can be observed over tine, regardless
of who is observing (a fact)
experimental group
group who experiences the experimental manipulation to answer the research question. (the cause, or independent variable)
experimenter bias
researcher expectations skew the results of the study
falsifiable
able to be disproven by experimental results
generalize
results for a sample can apply to the larger population
hypothesis
tentative and testable statement
illusory correlation
when a false relationship is drawn between two things when no such relationship exists
independent variable
variable that is influenced or controlled by the experimenter. (experimental group, or the cause)
inductive reasoning
conclusions drawn from observations
informed consent
informing a research participant about what to expect, any risks involved, and the implications of the research, and then obtaining the person’s
consent to participate
