Replication
A study that is _____is reproducible; this does not mean that the study could hypothetically be replicated, but rather that the result has been repeated.
Replicable
How well a conceptual variable is operationalized
Construct Validity
A series of related studies conducted by different researchers who have tested similar variables.
Scientific literature
A subdiscipline in psychology focusing on how cultural contexts shape human thinking, feeling, and behavior.
Cultural psychology
Serves the same purpose as an independent variable, but researchers do not have full experimental control over it.
Quasi-independent variable
The original study is repeated as closely as possible to determine whether the original effect is found in the new data.
Direct replication (aka exact replication)
every member of the population of interest has an equal chance of being selected for the sample.
probability/random sampling
Daily Double!
HARK
Typically used when testing association claims or causal claims to investigate whether there is support for a particular theory.
Theory-testing mode
In conducting quasi-experimental designs, researchers tend to give up some ________ in exchange for ________.
Internal Validity; External Validity
Replicability helps interrogate which of the four big validities?
External Validity
turn a conceptual definition into a measured or manipulated variable
Operational definition
A meta-analysis might overestimate the true effect size because null effects (or opposite effects) haven’t been included in the analysis
File drawer problem
Sometimes studies conducted in laboratories can feel very real. Their tasks might be similar to tasks we do in the real world, and might make people experience authentic emotions, motivations, and behaviors.
Experimental realism
What is the difference between a quasi-independent variable and a participant variable?
Participant variables are associated with social identities. Quasi-independent variables focus more on interventions.
Researchers replicate the original study but add some variables to test additional questions.
Replication-plus-extension
summary of the article; read it to figure out what the article is about.
Abstract
When researchers publish the hypothesis and study design before data collection and analysis begin.
Preregistration
Daily Double
Another name for ecological validity
What is the difference between a correlation and a quasi-experiment?
Quasi-experiments do a little more meddling
Researchers explore the same research question but use different procedures.
Conceptual replication
a specific prediction based on theory
hypothesis
When researchers analyze data in many different ways, so the result is more likely to be a fluke.
p-hacking
This is the real world; it has high external validity (specifically, high ecological validity).
Field setting
If quasi-experimental studies can be vulnerable to internal validity threats, why would a researcher use one?
Ethics; Real-world opportunities
