Categories are often structured by the similarities of instances within the category defined across dimensions or features. Researchers typically assume that there is a direct, linear relationship between the physical input dimensions across which category exemplars are defined and the psychological representation of these dimensions. However, this assumption is not always warranted. Through a set of simulations, we demonstrate that the psychological representations of input dimensions developed through long-term prior experience can place very strong constraints on category learning. We compare the model's behavior to auditory, visual, and cross-modal human category learning and make conclusions regarding the nature of the psychological representations of the dimensions in those studies. These simulations support the conclusion that the nature of psychological representations of input dimensions is a critical aspect to understanding the mechanisms underlying category learning.

Background: The National Lung Screening Trial (NLST) has shown that screening with low dose CT in high-risk population was associated with reduction in lung cancer mortality. These patients are also at high risk of coronary artery disease, and we used deep learning model to automatically detect, quantify and perform risk categorisation of coronary artery calcification score (CACS) from non-ECG gated Chest CT scans.
Materials And Methods: Automated calcium quantification was performed using a neural network based on Mask regions with convolutional neural networks (R-CNN) for multiorgan segmentation.

Background: Classroom behavior is one of the important variables for the curriculum in the learning path of learners. The aim of this study was to explain the classroom behavior process of medical sciences students.
Materials And Methods: In a qualitative study using the grounded theory approach, the classroom behavior of 21 students from different medical fields was assessed.

Background: Providing quality palliative care during a pandemic was challenging. Both specialist and community healthcare services cared for patients that faced life-threatening illness and who were influenced by the restrictions of the COVID-19 pandemic. Little knowledge has yet been provided on how registered nurses (RNs) experienced the palliative care quality during the COVID-19 pandemic.

Tonal short-term memory has been positively associated with both incidentally acquired absolute pitch memory (e.g., for popular songs) and explicitly learned absolute pitch (AP) categories; however, the relationship between these constructs has not been directly tested within the same individuals.
View Article and Find Full Text PDFLearning engagement has attracted increasing interest in recent years, with teacher support, academic self-efficacy, psychological resilience, and positive academic emotion identified as key factors. However, the moderated mediating mechanisms between teacher support and learning engagement remain unexplored. This study aimed to investigate the roles of academic self-efficacy and psychological resilience as mediators, and positive academic emotion as a moderator, in the relationship between teacher support and secondary school students' learning engagement, from the perspective of the Self-determination Theory and Emotion Regulation Theory.
