BCABA Experimental Design and Research Methods 2

Question 1

Which threat to internal validity occurs when unplanned events outside the study coincide with behavior change?

Accepted Answer

History

Answer

History refers to external events that occur concurrently with the intervention and could account for observed behavior change.

Question 2

The independent variable in a behavior analytic experiment is:

Accepted Answer

The intervention or treatment being manipulated

Answer

The independent variable is what the researcher deliberately manipulates to determine its effect on behavior.

Question 3

Social validity in ABA research refers to assessing the:

Accepted Answer

Meaningfulness and acceptability of goals, procedures, and outcomes

Answer

Social validity measures whether the intervention's goals, procedures, and outcomes are valued and considered acceptable by stakeholders.

Question 4

A nonconcurrent multiple baseline design differs from a concurrent multiple baseline in that:

Accepted Answer

Baselines for different tiers are collected at different points in time

Answer

In a nonconcurrent multiple baseline, the different tiers (participants, behaviors, or settings) are not observed at the same time, reducing the ability to rule out confounds.

Question 5

Replication across participants in single-subject research increases:

Accepted Answer

External validity and generality of findings

Answer

Replicating findings across multiple participants extends external validity by showing the effect is not limited to one individual.
