empricism: the use of verifiable evidence as the basis for conclusion; collecting data systematically and using it to develop/ support or challenge a theory
theory: a set of statements that describes general principles about how variables relate to one another
hypothesis:prediction
data: set of observations
theory- data cycle: theory- research queditions- research design- hypothesis (preregistered)- data
preregistration: the researcher states publicly what the study’s outcome is expected to be (before collecting any data)
scientists don’t prove theories: data support or is consistent
weight of the evidence: a conclusion drawn from reviewing scientific literatur/ considering the proportion of studies that is consistent with a theory
a good theory is falsifiabl: possible to collect data that will indicate that the theory is wrong
disinterestedness: discover the truth no matter what, accept what the data tells them, not influenced by their own beliefs
organized skepticism: questions everything, asks to see evidence
applied research: practical problem
basic research: enhance general body knowledge
translational research: lessons from basic resea to develop/ test applications to healthcare or other forms of treatment
confounds: potential alternative explanation for a research finding; a threat to internal validity
confederate: an actor playing a specific role for the experimenter
probabilistic: its findings do not explain all cases all of the time
availability heuristic: things that pop up easily in our mind tend to guide our thinking (overestimating events)
presen/ present bias: reflects our failure to consider appropriate comparison groups
confirmation bias: cherry picking the information we take in- seeking and accepting only the evidence that supports what we already think
bias blind spot: thinking that you as an individual is less biased than others, but you are not
empirical journal article: report for the first time the results of (empirical) research study
review journal article: summarize and integrate all the published studies that have been done in one research area
meta-analysis: combines the results of many studies and gives a number that summarizes the magnitude
effect size: the strength of a relationship between 2 or more variables
construct validity: how well a variable was measured or manipulated in a study
generalizability: how did the researchers choose the study’s participants ..how well do those participants represent the intended populationg
external validity: how well the results of a study represent people or contexts besides those in the original study
statistical validity: how well the members support the claim
covariance: the extent to which the variables are observed to go together
temporal precedence: the method was designed so that the causal variable clearly comes first in time before the effect variable
internal validity: a study’s ability to eliminate alternative explanations for the association
debriefed: carefully informed about the stud’s hypotheses afterward
The Belmont Report (1979) :A document that outlines the ethical principles that guide researchers in the conduct of research.
respectforpersons: research participants should be treated as autonomous agents who have the right to decide whether or not to participate in research
informed consent: the right of a participant to know about a project, its risks and benefit/ decide whether to participate
specialprotection:children, people with disabilities and prisoners
beneficence: researchers must maximize benefits and minimize harm to participants
justice: fair distribution of burdens and benefits among those involved in research
