A researcher claims their single-subject intervention is ready for broad application after testing it on three similar students in a single classroom. To evaluate the merit of this claim, a peer reviewer would note that the researcher lacks evidence from _____ replication, which is necessary to determine if the effect holds across different participant types or environmental settings.

How do single-subject researchers primarily build confidence in the external validity of their findings?
Match each strategy used to enhance the external validity of single-subject research with its specific role in the scientific process.
A researcher finds that a specific 'sensory break' reduces disruptive behaviors for a child with autism in a quiet classroom. If the researcher then implements the same sensory break for the same child in the same classroom the following week to ensure the results are consistent, they are performing a systematic replication to increase external validity.
A researcher has demonstrated that a specific 'pause-and-think' strategy reduces impulsive errors for a 9-year-old student during math tasks in a private tutoring session. Arrange the following replication attempts in the order that logically builds a case for the external validity of this strategy, progressing from the most similar conditions to the most diverse.
In single-subject research, researchers build confidence in the external validity of their findings by systematically replicating the study using different small samples or varied environmental conditions.
A researcher has found that using a 'visual schedule' significantly reduces anxiety for a 7-year-old child with autism in a private therapy clinic. To build confidence in the external validity of this finding through systematic replication, match each follow-up study scenario to the specific factor it varies.
A researcher has developed a social-skills intervention and needs to build a case for its external validity using a single-subject approach. Arrange the following steps in the logical order they should be performed to transition from an initial success to a claim of generalizability.
Systematic replication in single-subject research involves attempting to reproduce observed effects by using the exact same participants under identical environmental conditions.
In single-subject research, what is the primary method used to build confidence in the external validity of the findings?
A peer reviewer evaluates a single-subject study on a new therapy and notes that while the results are consistent for one patient, the study fails to address the treatment's effectiveness for different age groups. To meet the reviewer's criteria for evaluating the study's generalizability, the researcher should have performed _____ replication.
