Studies on the effects of acute bouts of cardiovascular exercise on cognitive performances show contradictory findings due to methodological differences (e.g., exercise intensity, cognitive function assessed, participants' aerobic fitness level, etc.). The present study assessed the acute effect of exercise intensity on cognition while controlling…

The present study uses panel data models to control unobserved characteristics and to investigate how the presence of spouses in interviews influences reports regarding housework and earnings contributions. Both husbands and wives relatively overreport their housework contributions but do not overreport their earnings contributions. The amount of…

Two experiments investigated response tendencies of preschoolers toward yes-no questions about actions. Two hundred 2- to 5-year-old children were asked questions concerning actions commonly associated with particular objects (e.g., drinking from a cup) and actions not commonly associated with particular objects (e.g., kicking a toothbrush). The…

Remembering temporal information associated with personal past events is critical. Yet little is known about the development of temporal order memory for naturally occurring events. In the current research, 8- to 10-year-old children and adults took photographs daily for 4 weeks. Later, they participated in a primacy/recency task (were shown 2 of…

Why are dual-task costs reduced with ideomotor (IM) compatible tasks (Greenwald & Shulman, 1973; Lien, Proctor & Allen, 2002)? In the present experiments, we first examine three different measures of single-task performance (pure single-task blocks, mixed blocks, and long stimulus onset asynchrony [SOA] trials in dual-task blocks) and two…

Binary-choice reactions are typically faster when the stimulus location corresponds with that of the response than when it does not. This advantage of spatial correspondence is known as the "stimulus-response compatibility" (SRC) effect when the mapping of stimulus location, as the relevant stimulus dimension, is varied to be compatible or…

The pattern of shading across an image can provide a rich sense of object shape. Our ability to use shading information is remarkable given the infinite possible combinations of illumination, shape and reflectance that could have produced any given image. Illumination can change dramatically across environments (e.g. indoor vs. outdoor) and times…

In this commentary, Martin Holtmann, discusses Doehnert and colleagues' article in this issue (Doehnert et al., 2013). Holtmann comments that the article illustrates the value of longitudinal electrophysiological and experimental approaches to disentangle different pathways underlying the phenotype of ADHD, and points out that their…

A large body of literature exists on evolutionary computing, genetic algorithms, decision trees, codified knowledge, and knowledge management systems; however, the intersection of these computing topics has not been widely researched. Moving through the set of all possible solutions--or traversing the search space--at random exhibits no control…

Interdisciplinary research in computer science requires the development of computational techniques for practical application in different domains. This usually requires careful integration of different areas of technical expertise. This dissertation presents image and time series analysis algorithms, with practical interdisciplinary applications…

Maximizing training efficiency is desirable in many areas of business. The ever increasing costs of flight training combined with a predicted shortage of pilots have resulted in steps being taken to improve flight training efficiency. In the past, the majority of airline pilots received their flight training in the military. Over time a growing…

Objective: ADHD is often associated with difficulties in planning and time management. In this study, the authors examined the hypothesis that these functional problems in ADHD reflect systematic biases in temporal orientation. Method: To test this hypothesis, adults with ADHD (n = 30) and healthy controls (n = 60) completed the Swedish version of…

Much has been written recently on the increased pace of scholarly life and its ill effects. More generally, work intensification has been identified as a widespread malaise in contemporary workplaces, and academia is no exception. In this article the authors make the argument that the kind of higher order thinking that is a critical part of the…

Time, an everyday yet fundamentally abstract domain, is conceptualized in terms of space throughout the world's cultures. Linguists and psychologists have presented evidence of a widespread pattern in which deictic time--past, present, and future--is construed along the front/back axis, a construal that is "linear" and…

The purpose of this article is to describe the construction of a Sun clock and calendar (SCandC) that will allow an observer to not only see the time but also the symmetry properties of the Sun-Earth relative movement. A set of circles drawn on the SCandC will allow the observer to see their associated dates as well as to perform a visual…
