Study 2
•15 participants (12 Female; age M= 21 years, SD = 3).
•Experimental procedure differed from Study 1: in target scenes,
participants had to confirm their initial choice by clicking on a blue dot
or cloud area.
The Similar Situations Task: An Assessment of
Analogical Reasoning in Healthy and Clinical Populations
Introduction
•Traditional assessments of analogical reasoning, such as 4-term
verbal analogy problems, are often insensitive at capturing reasoning
deficits in clinical populations (e.g., traumatic brain injury patients).
•A sufficiently challenging and sensitive analogical reasoning task
could help to better characterize executive function deficits in such
populations, as well as inform cognitive rehabilitation programs.
Method
•The Similar Situations Task (SST) presented participants with 48 line-
art scene analogy problems in source–target pairs.
•In each source scene one or two arrows directed participants to
encode and remember the relations and roles of the items pointed to.
•For each target scene, participants were tasked with identifying which
item, if any, was in a similar situation as one pointed to in the source.
•If no close analog was present, participants could click “No Match.”
•Participants then rated their confidence (from -4 to 4) in their answer.
•After the SST, various other cognitive and neuropsychological
measures (different between Studies 1 and 2) were administered.
•Four trial types (see columns) were presented in pseudorandom order.

Study 1
•38 participants (25 Female; age M = 23 years, SD = 7).
•SST Calibration—how accurate a person is in their confidence rating—was
calculated by multiplying each participant’s confidence rating by the
accuracy (1 if correct or -1 if incorrect) for each trial.

For SST accuracy, we observed main effects of relational load, F(1, 37) = 4.19, p= .048, and matchability,
F(1, 37) = 29.81, p< .001, but no interaction. Similarly, for SST RT for correct trials, we observed main
effects of relational load, F(1, 37) = 18.30, p< .001, and matchability, F(1, 37) = 8.26, p = .007, but not
their interaction. Error bars represent SEM.
For SST accuracy, we observed a main effect of matchability, F(1, 14) = 15.90, p= .001, but no main
effect of relational load nor their interaction. However, for SST RT for correct trials, we observed main
effects of relational load, F(1, 14) = 12.27, p= .004, and matchability, F(1, 14) = 7.72, p = .015, but not
their interaction. Error bars represent SEM.

Principal Component Analysis 2
Inferential principal component analyses1,2 were performed using permutation and bootstrapping techniques across 2,000 iterations to calculate significance for components and measures, respectively. Significant
measures had bootstrap ratios greater than 2 (p < .05).Dot sizes signify contributions1, or how much variance each measure contributes to the components, with greater sizes signifying larger contributions.

Discussion
•Variability of performance on the SST across healthy individuals and how SST performance relates to performance on clinically relevant
cognitive measures suggests that the SST may be sensitive to executive function deficits in clinical populations.
•Future work will investigate the efficacy of the SST in predicting difficulties in everyday reasoning within various clinical groups.
