This study explored developmental and individual differences in intellectual humility (IH) among 127 children ages 6-8. IH was operationalized as children's assessment of their knowledge and willingness to delegate scientific questions to experts. Children completed measures of IH, theory of mind, motivational framework, and intelligence, and neurophysiological measures indexing early (error-related negativity [ERN]) and later (error positivity [Pe]) error-monitoring processes related to cognitive control. Children's knowledge self-assessment correlated with question delegation, and older children showed greater IH than younger children...

The success of the state-of-the-art deblurring methods mainly depends on restoration of sharp edges in a coarse-tofine kernel estimation process. In this paper, we propose to learn a deep convolutional neural network for extracting sharp edges from blurred images. Motivated by the success of the existing filtering based deblurring methods, the proposed model consists of two stages: suppressing extraneous details and enhancing sharp edges. We show that the two-stage model simplifies the learning process and effectively restores sharp edges...

Behavioural inflexibility and associated atypical learning behaviours are common clinical manifestations of the autism spectrum disorder (ASD) phenotype. Despite advances in our understanding of ASD, little research has been devoted to experimental interventions that might help to circumvent behavioural inflexibility in ASD. The current paper suggests that motivational locomotion in the form of wheel running can reduce behavioural inflexibility and learning impairments in an ASD rat model, and discusses how the strategy of reward-coupled locomotor activity may lead to clinical interventions for children with ASD...

This paper presents several geometrically motivated techniques for the visualization of high-dimensional biological data sets. The Grassmann manifold provides a robust framework for measuring data similarity in a subspace context. Sparse radial basis function classification as a visualization technique leverages recent advances in radial basis function learning via convex optimization. In the spirit of deep belief networks, supervised centroid-encoding is proposed as a way to exploit class label information...

The use of student directed study approaches such as Enquiry Based Learning (EBL) in the design and implementation of Graduate Entry Nursing Circular is well established. The rational relates to the maximisation of graduate attributes such as motivation to learn, the ability to identify, search and assimilate relevant literature and the desire to take ownership of the direction and pace of learning. Existing alongside this however, is the observation that students remain under confident in the application of knowledge to a clinical context and frustrated with learning approaches which do not appear directly related to improving their competence in this area...

BACKGROUND: The objective of this study is to compare two different instructional methods in the curricular use of computerized virtual patients in undergraduate medical education. We aim to investigate whether using many short and focused cases - the key feature principle - is more effective for the learning of clinical reasoning skills than using few long and systematic cases. METHODS: We conducted a quasi-randomized, non-blinded, controlled parallel-group intervention trial in a large medical school in Southwestern Germany...

BACKGROUND: Atrial fibrillation (AF) is often asymptomatic and undiagnosed until an ischaemic stroke occurs. An irregular pulse is a key manifestation of AF. We assessed whether pulse self-palpation is feasible in screening of AF. METHODS: Altogether 205 residents of Lieto municipality aged ≥75 years were randomized in 2012 to receive brief education on pulse palpation focusing on evaluating rhythm regularity. Self-detected pulse irregularity and new AF diagnoses were recorded, and the subjects' quality of life and use of health care services were assessed during a three-year follow-up...

Diffusion magnetic resonance imaging (dMRI) captures the anisotropic pattern of water displacement in the neuronal tissue and allows noninvasive investigation of the complex tissue microstructure. A number of biophysical models have been proposed to relate the tissue organization with the observed diffusion signals, so that the tissue microstructure can be inferred. The Neurite Orientation Dispersion and Density Imaging (NODDI) model has been a popular choice and has been widely used for many neuroscientific studies...

Children's mindsets about intelligence (as a quality they can grow vs. a trait they cannot change) robustly influence their motivation and achievement. How do adults foster "growth mindsets" in children? One might assume that adults act in ways that communicate their own mindsets to children. However, new research shows that many parents and teachers with growth mindsets are not passing them on. This article presents a new perspective on why this is the case, and reviews research on adult practices that do instill growth mindsets, concluding that a sustained focus on the process of learning is critical...

Caenorhabditis elegans is one of the most important model organisms in the study of biology. It is ideal for laboratory teaching due to its short life cycle and low cost. It enriches the teaching content and can motivate students' interest of learning. In this article, we have shown cased C. elegans for the observation of life cycle and mating, as well as the investigation of single nucleotide polymorphism (SNP) and RNA interfere. In addition, we also discuss the details of the experimental design, basic requirement, preparations and related information...

Mating is critical for species survival and is profoundly regulated by neuromodulators and neurohormones to accommodate internal states and external factors. To identify the underlying neuromodulatory mechanisms, we investigated the roles of dopamine receptors in various aspects of courtship behavior in Drosophila. Here we report that the D1 dopamine receptor dDA1 regulates courtship drive in naïve males. The wild-type naïve males actively courted females regardless their appearance or mating status. On the contrary, the dDA1 mutant (dumb) males exhibited substantially reduced courtship toward less appealing females including decapitated, leg-less and mated females...

Humans are able to intuitively exploit the shape of an object and environmental constraints to achieve stable grasps and perform dexterous manipulations. In doing that, a vast range of kinematic strategies can be observed. However, in this work we formulate the hypothesis that such ability can be described in terms of a synergistic behavior in the generation of hand postures, i.e., using a reduced set of commonly used kinematic patterns. This is in analogy with previous studies showing the presence of such behavior in different tasks, such as grasping...

INTRODUCTION: Deployment and retention of a sufficient number of skilled and motivated human resources for health (HRH) at the right place and at the right time are critical to ensure people's right to access a universal quality of health care. Vision Tokyo 2010 Network, an international network of HRH managers at the ministry of health (MoH) level in nine Francophone African countries, identified maldistribution of a limited number of healthcare personnel and their retention in rural areas as overarching problems in the member countries...

Background: Cognitive training is effective in patients with mild cognitive impairment but does not typically address the motivational deficits associated with older populations with memory difficulties. Methods: We conducted a randomized controlled trial of cognitive training using a novel memory game on an iPad in 42 patients with a diagnosis of amnestic mild cognitive impairment assigned to either the cognitive training (n=21; 8 hours of gameplay over 4 weeks) or control (n=21; clinic visits as usual) groups...

The ventral tegmental area (VTA) dopamine system is important for reward, motivation, emotion, learning, and memory. Dysfunctions in the dopamine system are linked to multiple neurological and neuropsychiatric disorders, many of which present with sex differences. Little is known about the extent of heterogeneity in the basic organization of VTA dopamine neurons with regard to sex. Here, we characterized the cell-specific connectivity of VTA dopamine neurons, their mRNA translational profile, and basic electrophysiological characteristics in a common strain of mice...

Background and Objectives: Among the clinical skills needed by all physicians, history taking is one of the most important. The teaching model for peer-assisted history-taking groups investigated in the present study consists of small-group courses in which students practice conducting medical interviews with real patients. The purpose of this pilot study was to investigate the expectations, experiences, and subjective learning progress of participants in peer-assisted history-taking groups. Methods: The 42 medical student participants completed a 4-month, peer-assisted, elective history-taking course, which both began and ended with a subjective assessment of their interview skills by way of a pseudonymized questionnaire...

Background: Medical students often have a problem recognising the relevance of basic science subjects for their later professional work in the pre-clinical stage of their studies. This can lead to a lower motivation to learn biochemical content and dissatisfaction in the courses amongst the students. Alternative teaching methods such as the Inverted Classroom (IC) method can address this deficiency. The goal of this study was: to analyse the motivation and satisfaction of the students in a biochemistry seminar through the use of the e-learning-based IC method, to investigate the acceptance against the IC teaching method in biochemistry, and to compare the learning success achieved using the IC approach with that of a traditional course...

Chronic stress leads to a dysregulated inhibitory tone that could impact hippocampal-dependent spatial learning and memory. The present study examined whether spatial memory deficits resulting from chronic stress could be overcome by antagonizing the GABAA receptor, a prominent inhibitory receptor of GABA in the hippocampus. Young adult male Sprague-Dawley rats were chronically stressed (STR, wire mesh restraint, 6h/d/21d) or placed in a no-stress control group (CON). When chronic restraint ended, rats were tested on a 2-trial object placement (OP) task at a delay (3hr) that would result in chance performance without intervention and then on novel object recognition (NOR) and the elevated plus maze (EPM) to assess non-spatial memory and anxiety profile...
