Latency in Visual Inspection
During the visual inspection of single-subject data, latency refers to the duration of time it takes for the dependent variable to begin altering after conditions are changed. A short latency, where the behavior shifts almost immediately following the introduction of a new condition, provides strong evidence that the treatment was directly responsible for the change.

Statistical Analysis in Single-Subject Research
What is the primary method of data analysis used in single-subject research to determine the effect of the independent variable?
In single-subject research, visual inspection is used to calculate the statistical significance (p-value) of an independent variable's effect.
A researcher is conducting a visual inspection of a graph from a single-subject study to determine the effect of an intervention. Match each observation of the data with the corresponding component of visual inspection being applied.
Arrange the following hypothetical outcomes of a visual inspection in order from the pattern that provides the weakest evidence of a treatment effect to the pattern that provides the strongest evidence of a treatment effect.
You are tasked with designing the data analysis protocol for a new single-subject research study. To correctly establish a visual inspection methodology, which of the following procedures should you construct?
Arrange the steps of visual inspection in single-subject research in the correct chronological order, as they are typically performed during data analysis.
A researcher studying a participant's social anxiety observes that the participant initiated 10 conversations per day during the baseline phase and 11 per day during the treatment phase. If the researcher concludes the therapy was ineffective because this slight change was not large enough to be clearly seen on the graph, they are evaluating that the therapy did not have a(n) _____ effect.
Learn After
During the visual inspection of single-subject data, what term describes the duration of time it takes for the dependent variable to begin altering after a new condition is introduced?
In single-subject research, a long latency period between the start of an intervention and the observed change in behavior increases the researcher's confidence that the intervention was the specific cause of that change.
A researcher is evaluating data from three different single-subject studies. Rank the following scenarios from the strongest evidence that the treatment caused the change to the weakest evidence, based specifically on the observed latency of the behavior change.
Analyze the following data scenarios from a single-subject research design. Match each observation of the dependent variable's behavior to the analytical conclusion that can be drawn regarding the intervention's effectiveness based on latency.
In single-subject research, why does a researcher's confidence in the effectiveness of a treatment increase when they observe a 'short latency' between the start of the intervention and the change in behavior?
In single-subject research, a short latency between the introduction of a new condition and a change in behavior provides strong evidence that the _____ was directly responsible for that change.
When a researcher determines that a behavior change provides weak evidence for a treatment's effectiveness because the shift occurred only after a significant delay following the start of the intervention, they are basing their negative evaluation on the observed _____.
A clinical psychologist is evaluating a client's hand-washing behavior in a single-subject design. Immediately after the psychologist introduces a mindfulness intervention, the frequency of hand-washing drops significantly. According to the principles of latency in visual inspection, this immediate change represents a short latency and provides strong evidence that the mindfulness intervention was directly responsible for the change.
Analyze the following descriptions of single-subject research observations and match each to its correct visual inspection concept or conclusion regarding latency.
Evaluate the following single-subject data scenarios. Order them from the strongest evidence of treatment effectiveness (1) to the weakest evidence of treatment effectiveness (3), based solely on the latency of the behavioral change.
Define the concept of latency as it is used during the visual inspection of single-subject data, and recall what a short latency suggests about the relationship between the treatment and the behavior change.
Based on the concept of latency in single-subject research, explain how the psychologist should interpret this immediate change in the child's behavior, and explain why this pattern affects the strength of the evidence for the treatment's effectiveness.
A researcher changes conditions in a single-subject study. If they observe a behavior shift that occurs only after a long delay versus a behavior shift that occurs almost immediately, how should they apply the concept of latency to evaluate which scenario provides stronger evidence of the treatment's effect?
