“…The Dunning-Kruger effect can be observed in a wide range of domains, but may be modulated by individual personality traits. 24 Computerbased software technologies (Sirona Bensheim, Germany, and Planmeca E4D Technologies, Richardson, TX, USA) are now available to reduce the subjectivity of evaluations. These technologies used in conjunction with faculty guidance have demonstrated that students can learn to selfassess their work, although unfortunately, these technologies were not available at our school.…”

Objective of this study was to determine if perceptual abilities test (PAT), quantitative reasoning (QR), and academic average (AA) scores predict performance in a rudimentary dental anatomy laboratory exercise.Methods: First-year dental students (n = 88) completed two identical wax carving exercises during the first and last weeks of the dental anatomy course. After being given detailed instructions and a wax block, students carved a cube and a semilunar shape using the wax subtraction technique. Using a rubric, students self-assessed their work as unsatisfactory, satisfactory, or ideal in the following areas: finish, sharpness, symmetry, and accuracy. Two calibrated and blinded faculty graded the exercise using the same rubric as the students. Cohen's kappa coefficient assessed faculty interrater reliability and student-faculty reliability. Changes in scores between the two exercises were evaluated using Wilcoxon signed rank and paired t-tests. Spearman's correlation coefficient and repeated measures analysis assessed the association between shape carving scores and DAT, QR, and AA scores.Results: Faculty interrater reliability ranged from 0.2554 to 0.4186 for the assessed criteria over the two exercises. Student-faculty rater reliability ranged from 0.1299 to 0.4461. Only PAT scores correlated significantly to higher scores for the four grading criteria for both exercises. Student self-assessment improved with the second exercise. Conclusions: This rudimentary exercise was useful to identify students early in their dental education who may require more guidance in other manual dexterity courses. Faculties require additional training and calibration. Self-assessment is a life-long process of critical thinking that students are just beginning to learn.

“…This quartile-split approach is a standard approach in metacognition research that was firstly introduced by Dunning et al (2003). This method has been widely used since then to study metacognition in different cognitive processes, including reasoning (Pennycook et al, 2017), intelligence (Unsworth & Engle, 2005), working memory (Adam & Vogel, 2017) and, more recently, face perception (Zhou & Jenkins, 2020). The aim of this approach is to have four subgroups of participants of approximately the same size, representing different degrees of performance in the task (i.e., Q1: low performance, Q2: low-average performance, Q3: average-high performance, Q4: high performance).…”

The 20-Item Prosopagnosia Items (PI-20) was recently introduced as a self-report measure of face recognition abilities and as an instrument to help the diagnosis of prosopagnosia. In general, studies using this questionnaire have shown that observers have moderate to strong insights into their face recognition abilities. However, it remains unknown whether these insights are equivalent for the whole range of face recognition abilities. The present study investigates this issue using the Mandarin version of the PI-20 and the Cambridge Face Memory Test Chinese (CFMT-Chinese). Our results showed a moderate negative association between the PI-20 and the CFMT-Chinese. However, this association was driven by people with low and high face recognition ability, but absent in people within the typical range of face recognition performance. The implications of these results for the study of individual differences and the diagnosis of prosopagnosia are discussed.

“…[9,19]). But identifying super-recognizers based on self-report alone is unreliable [20,21], with high performers consistently underestimating their own face identification ability [22]. As a result, screening based on self-report is better suited for detecting deficits-rather than superiority-in face identification ability (e.g.…”

UNSW Face Test: A screening tool for super-recognizers

We present a new test–the UNSW Face Test (www.unswfacetest.com)–that has been specifically designed to screen for super-recognizers in large online cohorts and is available free for scientific use. Super-recognizers are people that demonstrate sustained performance in the very top percentiles in tests of face identification ability. Because they represent a small proportion of the population, screening large online cohorts is an important step in their initial recruitment, before confirmatory testing via standardized measures and more detailed cognitive testing. We provide normative data on the UNSW Face Test from 3 cohorts tested via the internet (combined n = 23,902) and 2 cohorts tested in our lab (combined n = 182). The UNSW Face Test: (i) captures both identification memory and perceptual matching, as confirmed by correlations with existing tests of these abilities; (ii) captures face-specific perceptual and memorial abilities, as confirmed by non-significant correlations with non-face object processing tasks; (iii) enables researchers to apply stricter selection criteria than other available tests, which boosts the average accuracy of the individuals selected in subsequent testing. Together, these properties make the test uniquely suited to screening for super-recognizers in large online cohorts.
