Field Experiment

External Validity

What is the primary defining characteristic of a field study in psychological research?

A researcher who wants to maximize the ability to generalize their findings to everyday life would likely choose to conduct a field study rather than a laboratory experiment.

A researcher is deciding on the best setting to ensure their findings about social interaction are generalizable to everyday life. Arrange the following research scenarios in order from the one that provides the highest external validity (1) to the one that provides the lowest external validity (3), based on the naturalness of the environment.

Analyze the relationship between research context and generalizability by matching each term with the description that best captures its specific role in psychological research.

In the context of psychological research, which statement best captures the reason that a field study typically offers greater 'external validity' than a laboratory-based study?

A researcher is evaluating the trade-offs between strict variable control and real-world applicability for a study on helping behavior. They conclude that the artificiality of a laboratory would compromise the study's relevance to daily life. By making the judgment to prioritize generalizability and move the research into a natural environment, the researcher is opting for a(n) _____.

Research that is conducted in a natural, real-world environment rather than an artificial laboratory is referred to as a(n) _____ study.

A clinical psychologist wants to study how anxiety affects social interactions. They choose to observe participants in a busy local coffee shop rather than in a controlled laboratory room. Because this is a field study, they should expect their findings to have higher external validity but lower internal validity compared to a laboratory design.

Match each methodological characteristic of research settings with its correct description or implication based on the trade-offs of field studies.

Evaluate the research designs below based on the control they afford over extraneous variables. Arrange these scenarios in order from the design that provides the HIGHEST capability to support causal conclusions (highest internal validity) to the design that provides the LOWEST capability to support causal conclusions (lowest internal validity).
