Anxiety is being increasingly identified in Angelman syndrome (AS). Qualitative questions and quantitative assessments were used to evaluate for anxiety in 50 subjects with AS. In-person evaluations assessed behaviors concerning for anxiety and circumstances wherein they occurred. Caregivers completed anxiety and other behavioral rating scales.…

Pavlovian fear conditioning is a widely used behavioral paradigm for studying associative learning in rodents. Despite early recognition that subjects may engage in a variety of both conditioned and unconditioned responses, the last several decades have seen the field narrow its focus to measure freezing as the sole indicator of conditioned fear.…

Video-based learning (VBL) is popular, yet students tend to learn video material passively. Instilling teaching expectancy is a strategy to promote active processing by learners, but it is unclear how effective it will be in improving VBL. This study examined the role of teaching expectancy on VBL by comparing the learning outcomes and…

Information problem solving (IPS) is an important twenty-first century skill, but it is lacking at all age levels. One type of information problem, those of an ill-structured nature that require multiple iterations of (re)defining problems and formulating emerging solutions, can be particularly challenging but have received less attention in the…

This case study showcases the development of a work routine that facilitated collaboration between students and faculty. The work routine consisted of three phases. In the preparation phase, participants worked independently or in pairs, followed by the second phase, a meeting with presentations and discussions. After the meeting, participants…

The current study investigated the utility of the Brief Observation of Social Communication Change-Phrase Speech Young Fluent (BOSCC-PSYF) as an outcome measure of treatment response by analyzing the measure's psychometric properties and initial validity. The BOSCC coding scheme was applied to 345 administrations from 160 participants diagnosed…

Interpreting and incorporating machine learning technology from a human perspective helps define the role of product designers in the era of artificial intelligence. With this background, this study developed a 7-week design course about machine learning-based product design. Subsequently, in Fall 2023, a class with seven undergraduate students…

Educators often observe differences in students' writing productivity, with some students stopping early while others continue to write for the given time. This study demonstrates how planning and goal setting are related to these written production patterns. A Growth Mixture Model identified three groups of writers: the "Early…

Preventing panel members from attriting is a fundamental challenge for panel surveys. Research has shown that response behavior in earlier waves (response or nonresponse) is a good predictor of panelists' response behavior in upcoming waves. However, response behavior can be described in greater detail by considering the time until the response is…

A data-driven model where individual learning behavior is a linear combination of certain stylized learning patterns scaled by learners' affinities is proposed. The absorption of stylized behavior through the affinities constitutes "building blocks" in the model. Non-negative matrix factorization is employed to extract common learning…

From an early age, children act generously towards one another, but the situational features that promote generous decision-making remain under investigation. The current study tests the impact of being identifiable--as a recipient of generosity, a giver, or both--on children's generosity. Six-year-old children (N = 129) allocated resources to a…

Practice occupies an essential and significant place in every musician's life, yet the practice habits of highly experienced, professional musicians, remain under-researched. As such, this study sought to contribute to the emerging body of knowledge into professional musicians' practice. Semi-structured interviews were undertaken with six such…

Item harvesters who memorize, record and share test items can jeopardize the validity and fairness of credentialing tests. Item harvesting behaviors are difficult to detect by the existing statistical modeling approaches due to the absence of operational definitions and the idiosyncratic nature of human behaviors. Motivated to detect the…

Background: Understanding the cognitive processes of individuals with intellectual disabilities in financially abusive situations is critical to develop effective prevention strategies. Aims: This study investigated how persons with intellectual disabilities define and analyse financially abusive situations, and how they would feel and act in…

Massive Open Online Courses (MOOCs) now offer a variety of options for everyone to obtain a high-quality education. The purpose of this study is to better understand the behaviours of MOOC learners and provide some insights for taking actions that benefit larger learner groups. Accordingly, 2,288,559 learners' behaviours on 174 MITx courses were…
