Excessive usage of electronic devices delays bedtime and increases nighttime arousal, reducing sleep duration of adolescents in the morning shift. The impacts of media use before bedtime (MBB) on sleep patterns and components of morning attention were evaluated in 89 adolescents (15.8 ± 0.8 years) using sleep questionnaires and a continuous…

Colleges and universities in the United States have embraced the "gig" economy with use of non-tenure track and part-time faculty. However, much of the work on job satisfaction in academia focuses on tenure-line professors. This study seeks to answer the question of whether adjunct faculty look more like independent gig workers or…

An ongoing debate points to a possible gap between the published research about and the delivery of leisure services. For example, two of the major research journals in the field of leisure studies, "Journal of Leisure Research" ("JLR") and "Journal of Parks and Recreation Administration" ("JPRA"), are…

Marketing instructors have long struggled with the issue of free-riding in groups. "Flocking" students based on shared motivation levels has been found to reduce free-riding among undergraduates, but this method may be less effective in graduate courses where student motivation is often more homogeneous. This article presents a modified…

A virtual learning environment (VLE) is a web-based platform that allows students to learn at a personally defined place, time and pace. However, most students are lacking in the self-regulation skills and metacognitive abilities to take advantage of the flexibility and high learners' control available in VLEs. The purpose of the study was to…

Dissection videos are commonly utilized in gross anatomy courses; however, the actual usage of such videos, as well as the academic impact of student use of these videos, is largely unknown. Understanding how dissection videos impact learning is important in making curricular decisions. In this study, 22 dissection videos were created to review…

Automaticity can be established by consistently reinforcing contingencies during practice. During reinforcement learning, however, new relations can also be derived, which were never directly reinforced. For instance, reinforcing the overlapping contingencies A [right arrow] B and A [right arrow] C, can lead to a new relation B-C, which was never…

The aim of this article is to shed light on the lifeworld of thirteen-year-olds with high and low activity levels in relation to movement activities. Insights on this topic could serve as important resources for all those who contribute to the development and life quality of young teenagers through various contexts involving movement activities.…

Purpose: Aphasia is a language disorder caused by acquired brain injury, which generally involves difficulty naming objects. Naming ability is assessed by measuring picture naming, and models of naming performance have mostly focused on accuracy and excluded valuable response time (RT) information. Previous approaches have therefore ignored the…

We describe the research and development of an NSF-funded, five-year experimental program to strengthen informal (out-of-school) STEM learning by youth in five rural communities. The central component of the model was a cadre of community members known as 'STEM Guides' who were hired to work as brokers between youth and the STEM learning resources…

The possible benefits of using music to enhance learning of STEM content are numerous, diverse, and largely unproven. We sought to determine which (if any) of these possible benefits are commonly experienced by undergraduate students and are thus especially worthy of further investigation. Four hundred ninety-three students in nine physiology…

The Dialogical Temporal Chair Technique (DTCT) is a method based on Hermans's dialogical self theory combined with Gestalt and cognitive-behavioural therapeutic techniques. The Dialogical Temporal Chair Technique is a method of activating temporal voices. Three chairs symbolising the past, present and future are used to help subjects create a…

We examined transitions occurring throughout the school day in an elementary school, sampling from kindergarten, second grade, and fourth grade classrooms. Unobtrusive observations and descriptive notetaking were used to gather data during six typical school days in the second half of the school year. Data were coded by committee to categorize the…

In this paper, we estimate a rich model of college major choice using a panel of experimentally-derived data. Our estimation strategy combines two types of data: data on self-reported beliefs about future earnings from potential human capital decisions and survey-based measures of risk and time preferences. We show how to use these data to…

Response-time models are of increasing interest in educational and psychological testing. This paper focuses on the lognormal model for response times (van der Linden, 2006), which is one of the most popular response-time models. Several existing statistics for testing normality and the fit of factor-analysis models are repurposed for testing the…
