Preknowledge cheating jeopardizes the validity of inferences based on test results. Many methods have been developed to detect preknowledge cheating by jointly analyzing item responses and response times. Gaze fixations, an essential eye-tracker measure, can be utilized to help detect aberrant testing behavior with improved accuracy beyond using…

This study examines and compares four person-fit statistics (PFSs) in the framework of the "D"- scoring method (DSM): (a) van der Flier's "U3" statistic; (b) "Ud" statistic, as a modification of "U3" under the DSM; (c) "Zd" statistic, as a modification of the "Z3 (l[subscript z])"…

Changepoints are abrupt variations in a sequence of data in statistical inference. In educational and psychological assessments, it is pivotal to properly differentiate examinees' aberrant behaviors from solution behavior to ensure test reliability and validity. In this paper, we propose a sequential Bayesian changepoint detection algorithm to…

Two new indices to detect answer copying on a multiple-choice test, S(1) and S(2) (subscripts), are proposed. The S(1) index is similar to the K-index (P. Holland, 1996) and the K-overscore(2), (K2) index (L. Sotaridona and R. Meijer, in press), but the distribution of the number of matching incorrect answers of the source (examinee s) and the…

Studied students' erasure behavior on a standardized (low stakes) test. Results for 5,641 students in grades 4, 8, and 11 suggest that students do change their responses at an average of 6 to 7% of the tested items and that overall achievement appears unrelated to the student's tendency to erase and change a response. Discusses conditions under…

Cheating behavior has been found to relate to emotion-attribution explanations. Prior research with second-grade children has indicated that increased self-control occurs in a watching task when the child's emotional response is attributed to internal rather than external actions. In the present study, freshman women (N=221) took a reading…

Some research has shown that women's achievements in traditionally masculine fields are devalued. To determine if females would be judged more harshly than males for performing unethical behaviors in order to gain entry in competitive professions, and to examine gender differences in the evaluation of unethical conduct, college students (52 males…

A study investigated the effectiveness of the Rasch procedure in measuring response appropriateness, especially for the detection of cheating on multiple-choice language tests. The report gives background information on appropriateness measurement and its potential uses, reviews recent research on cheating and its detection, and describes three…
