Question

What are three potential limitations of a multiple baseline across situations design?

a) Observer bias, low ecological validity, limited control.
b) Ethical concerns, experimenter bias, participant dropout.
c) High external validity, low internal validity, demand characteristics.
d) Limited generalizability, low reliability, observer effects.

Answer 1

The three potential limitations of a multiple baseline across situations design are observer bias, low ecological validity, and limited control.

Step-by-step explanation:

Multiple baseline across situations design is a research design used to evaluate the effectiveness of an intervention by comparing the behavior of a single participant across different situations. However, there are three potential limitations of this design:

1. Observer bias: Since the observers are involved in the research project, they may unconsciously skew their observations to fit their research goals or expectations.
2. Low ecological validity: This design may lack ecological validity as it focuses on a specific behavior in controlled situations, which may not generalize to real-world settings.
3. Limited control: Multiple baseline across situations design does not provide strong control over other factors that may influence behavior, making it difficult to establish a causal relationship between the intervention and behavior change.
