Pretest or not to pretest? A preliminary version of a tool for the virtual character standardization

2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW), 2021
This work-in-progress paper deals with pretesting of the virtual characters in VR psychological experiments. To make pretesting easier, the tool based on the combination of WebGL technology, Unity engine and psychological questionnaire was created. To test its efficacy we asked 13 judges to rate 15 models differing in terms of realism.

Pretesting effects in retrospective pretest-posttest designs.

Journal of Applied Psychology, 1989
Two studies evaluated communication skills training by using a pretest-posttest design, including retrospective pretest ratings, to control for response shift bias. A response shift is a change in a subject's internal standard for determining his or her level of functioning on a given dimension. In Exp 1, Ss were 37 hospital employees.

THE RETROSPECTIVE PRETEST AND THE ROLE OF PRETEST INFORMATION IN EVALUATIVE STUDIES

Psychological Reports, 1992
To test the effect of training programs, subjects are often given self-report questionnaires. When such self-report instruments are used, response-shift bias is a possible confounder of results. According to the response-shift theory, pretest information given to subjects might reduce or diminish response-shift bias.

Beyond the pretesting effect: What happens to the information that is not pretested?

Journal of Experimental Psychology: Applied, 2019
Taking a test before learning can enhance the long-term retention of the information that was tested, a phenomenon known as the pretesting effect. In the present research, we explored the consequences of pretesting on memory not only for the pretested information but also for nonpretested information. Across 5 experiments and various manipulations (the

The Traditional Pretest Estimator

Theory of Probability & Its Applications, 2000
Summary: We consider the problem of estimating \(k\) coefficients of interest in a linear regression model when the \((k+1)\)st coefficient is of no interest. The traditional pretest estimator is a two-step estimator of the coefficients of interest based on a t-test for the \((k+1)\)st coefficient. We study the behavior of this estimator.
