Conclusions: This simple computer-based drawing tool provides valid information on mental representation of mastoidectomy at its initial phase.
Objective: The aim of this study was to elaborate a simple computer-based drawing tool to assess the mental representation of mastoidectomy.
Methods: Twelve trainees in otology (five beginners, seven mid-level) and four otology experts participated in this prospective study. The image of a mastoid was displayed on a screen. All subjects reproduced the movements of mastoidectomy with a pen on a graphic tablet. Movements appeared as gray lines on the image. Surgeons were evaluated before and after a dissection course. The surface of mastoidectomy, perimeter, circularity, and the angle between traces and cavity edges were measured by Image J software.
Results: The total surface of mastoidectomy was higher in experts than in mid-level and beginner trainees (respectively 99 ± 6.5%, vs 57 ± 1.5%, and 22 ± 5.6%, p < 0.01 for experts vs beginners and p < 0.05 for experts vs mid-level, ANOVA and Bonferroni). Circularity was also higher in experts than in trainees. After training, total surface and circularity increased. The angle between traces and cavity edges was lower in experts than in trainees and was reduced after training.

The COVID-19 pandemic may have exacerbated mental health conditions by introducing and/or modifying stressors, particularly in university populations. We examined longitudinal patterns, time-varying predictors, and contemporaneous correlates of moderate-severe psychological distress (MS-PD) among college students. During 2020-2021, participants completed self-administered questionnaires quarterly (T1 = 562, T2 = 334, T3 = 221, and T4 = 169).

Mental representation of spatial information relies on egocentric (body-based) and allocentric (environment-based) frames of reference. Research showed that spatial memory deteriorates as Alzheimer's disease (AD) progresses and that allocentric spatial memory is among the earliest impaired areas. Most studies have been conducted in static situations despite the dynamic nature of real-world spatial processing.

From sequences of discrete events, humans build mental models of their world. Referred to as graph learning, the process produces a model encoding the graph of event-to-event transition probabilities. Recent evidence suggests that some networks are easier to learn than others, but the neural underpinnings of this effect remain unknown.

Sensory processing abnormalities have been noted since the first clinical description of autism in 1940. However, it was not until the release of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013 that sensory challenges were considered as symptoms of autism spectrum disorder (ASD). Multisensory processing is of paramount importance in building a perceptual and cognitive representation of reality.

Collocations typically refer to habitual word combinations, which not only occur in texts but also constitute an essential component of the mental lexicon. This study focuses on the mental lexicon of Chinese learners of English as a foreign language (EFL), investigating the representation of collocations and the influence of input frequency and L2 proficiency by employing a phrasal decision task. The findings reveal the following: (1) Collocations elicited faster response times and higher accuracy rates than non-collocations.
