Which of the following strategies is primarily used by single-subject researchers to address concerns regarding external validity?

To address concerns about external validity, single-subject researchers typically rely on random selection to ensure their small samples accurately represent the broader population.

A behavioral psychologist has found that a specific 'self-monitoring' checklist improves the study habits of a college student in a single-subject study. Arrange the following steps in the order the researcher should take to systematically build confidence in the external validity of this checklist using the single-subject approach.

Analyze the logic of single-subject research by matching each methodological strategy with the specific way it addresses concerns regarding external validity.

The principles of classical and operant conditioning are historical examples of findings discovered through single-subject research that have been successfully generalized across a wide range of species and situations.

Single-subject research is often criticized for having limited external validity due to its small sample sizes. Which of the following best describes the logic single-subject researchers use to demonstrate that their findings are generalizable?

Match each researcher action to the specific external validity strategy it illustrates in single-subject research.

Single-subject researchers counter external validity criticisms by arguing that the _____ of their observed effects makes generalization plausible even from a small sample—because an effect that appears powerfully and reliably across every session is less likely to be a fluke tied to one unusual individual—and by systematically replicating findings across different participants or conditions to accumulate converging evidence of the effect's breadth.

A graduate student is evaluating whether a published single-subject research program has adequately established external validity. Arrange the following evaluative steps in the most logical order for rendering a justified, evidence-based judgment.

When a critic challenges the generalizability of a single-subject study because of its small sample size, the researcher's most scientifically sound defense is to provide evidence through _____, which demonstrates that the findings remain consistent across different participants or conditions.

Based on the single-subject research methodology, state the two primary ways researchers address concerns about external validity, and identify a historical example of psychological principles discovered through single-subject research that successfully generalized across species and situations.

Explain how the psychologist can defend the generalizability of their initial findings using the characteristics of the observed effect, and explain what subsequent research steps they should take to systematically build confidence in the generality of these results.

Imagine you are conducting a single-subject study on a new biofeedback technique to reduce high blood pressure. You have found a strong, consistent reduction in blood pressure in your first participant. Apply the methodological principles of single-subject research to describe how you would design your next two steps to establish the external validity of this intervention.
