Question: According to advocates of group research, what are the three primary concerns regarding the visual inspection of data in single-subject designs? Describe each concern briefly.
Sample answer: The three primary concerns are: first, visual inspection may lack the sensitivity needed to detect weak treatment effects. Second, it can be unreliable, as different researchers might interpret the exact same data differently. Third, the overall judgments derived from visual inspection are difficult to efficiently summarize or compare across multiple studies.
Key points:
- Visual inspection may lack the sensitivity to detect weak treatment effects.
- Visual inspection can be unreliable due to different researchers interpreting the same data differently.
- Overall judgments from visual inspection are difficult to efficiently summarize or compare across multiple studies.
Rubric: Award 1 point for each correctly identified and described concern: 1) lack of sensitivity to detect weak treatment effects, 2) unreliability or differing interpretations among researchers, and 3) difficulty in summarizing or comparing overall judgments across multiple studies (maximum 3 points).

Defending Visual Inspection
What is one of the primary concerns raised by researchers regarding the visual inspection of data in single-subject designs?
Match each specific criticism of visual inspection in single-subject research with the concern it describes.
A clinical researcher conducts a single-subject study on a new meditation technique for stress reduction. While a statistical analysis would show a small but genuine decrease in the participant's cortisol levels, the researcher looks at the data graph and concludes there was no effect because the change was not visually obvious. This scenario highlights the criticism that visual inspection lacks _______.
Critics of single-subject designs often argue that visual inspection lacks the sensitivity required to detect weak treatment effects. Arrange the following hypothetical study outcomes in order from the one most likely to be missed (supporting the criticism) to the one least likely to be missed (showing a clear effect).
Evaluate the following claim: 'Visual inspection is a consistently objective method of analysis because different researchers will naturally reach the same conclusions when viewing the same graphical data.'
According to critics of single-subject designs, what is a major drawback of using visual inspection when a researcher wants to aggregate findings from several different studies?
If a researcher uses visual inspection and concludes there is no treatment effect, a critic might argue that a real effect was actually present but was simply too weak to be detected by the eye.
A researcher is deciding whether to rely on visual inspection in a single-subject study. Match each concrete research scenario to the criticism of visual inspection it best illustrates.
Two independent researchers, both trained in applied behavior analysis, examine the same multiple-baseline graph and reach opposite conclusions about whether the behavioral intervention was effective. This disagreement reveals that visual inspection has a problem with _____, a flaw that is conceptually distinct from the separate criticism that the method may be too insensitive to detect small but genuine treatment effects.
A methods instructor is constructing a lecture argument for why visual inspection alone may be insufficient for rigorous single-subject research. Arrange the following talking points in the logical order that builds the strongest cumulative case, from the most foundational measurement concern to the broadest scientific implication.
According to advocates of group research, what are the three primary concerns regarding the visual inspection of data in single-subject designs? Describe each concern briefly.
Explain how the researchers' disagreement and the psychologist's review paper plans illustrate the specific criticisms of visual inspection raised by advocates of group research.
A clinical researcher expects that a new cognitive training protocol will produce a real but very weak treatment effect on a patient's reaction time. Based on the criticisms of visual inspection, why should this researcher avoid relying solely on visual analysis to evaluate this specific intervention?
