A group of 12 reservation agent SMEs from a large urban municipality were used in the SJT development. The SMEs reported extensive on-the-job experience, with an average of 15.7 years. In addition, 42 active reservation agents were recruited as job incumbent test-taking respondents for this study. All respondents were Black, with eight being male a...
A group of 24 police officer subject matter experts from large municipal police departments were used in the SJT development. A total of 162 police officer candidates from a single large metropolitan police department were assessed on various measures as part of their preemployment screening. This number was reduced to 144 candidates after removing...
An audio SJT was developed for Study 1 that presented a series of ten audio scenarios of scripted critical incidents extracted from actual reservation agent telephone calls to create a high-fidelity audio SJT. The video SJT developed for Study 2 used content-validated critical incidents that were scripted and filmed for the purpose of providing dif...
SJT_Raw_Binary_Total scores are the sum of applicants’ binary (1 point for a correct response, and 0 for an incorrect) responses to the items on the SJT.
Binary logistic regression analysis (BLRA) statistics were generated by fitting a logistic regression function to each respondent’s set of binary responses (the dependent variable) and SME-estimated correctness valence contrasts (the independent variable). A separate logistic regression was conducted for each respondent and the regression parameter...

This article presents preliminary evidence for a theory of cognitive acuity (TCA), derived from psychophysical principles as a means for understanding and measuring an aspect of general mental functioning in the context of critical incident decision making on situational judgment tests (SJTs). Cognitive acuity is a new construct defined as the capacity to detect correctness and to distinguish ...
Sep 14, 2024 · To truly grasp the concept of acuity in psychology, we need to start at the beginning. The term “acuity” comes from the Latin word “acuitas,” meaning sharpness or acuteness. In psychology, acuity refers to the clarity or sharpness of a mental process or perception. It’s about how precisely we can detect, discriminate, or identify ...
Aug 1, 2012 · In this article, we present a theory of general acuity as an extension of Leeds’s (2012, 2018) theory of cognitive acuity. General acuity theory proposes that the higher a person’s standing on ...

The Theory of Cognitive Acuity: Extending Psychophysics to the Measurement of Situational Judgment Study 2 Hypothesis 4 and 5 proposed that cognitive acuity is a determinant of SJT performance and is indirectly related to on-the-job- performance ratings through the mediation of SJT scores. Applying the 4 step procedure of Baron and Kenny (1986) the data showed that SJT scores completely ...
