In the Gilbert et al.(1988)study of causal attribution discussed in the text,the researchers independently manipulated cognitive load (low vs.high)and discussion topics (anxiety-provoking vs.relaxing).Thus,the design of this study was:
A)a one-way,four-groups design
B)a Latin square factorial
C)a mixed-model design
D)a 2 x 2 factorial design

The study described has two independent variables: cognitive load (low vs. high) and discussion topics (anxiety-provoking vs. relaxing), thus making it a 2 x 2 design. This means that the participants were divided into four groups that received different combinations of the two variables, allowing the researchers to investigate the individual effects of each variable and their interaction on the outcome variable, which in this case was causal attribution.
