Background: Children with loss of control (LOC) eating and overweight/obesity have relative deficiencies in trait-level working memory (WM), which may limit adaptive responding to intra- and extra-personal cues related to eating. Understanding of how WM performance relates to eating behavior in real-time is currently limited.

Methods: We studied 32 youth (ages 10-17 years) with LOC eating and overweight/obesity (LOC-OW; n = 9), overweight/obesity only (OW; n = 16), and non-overweight status (NW; n = 7).

As Western societies become more ethnically and culturally diverse, understanding the acculturation of immigrant youth is essential for fostering social cohesion. How the cultural identity formation of ethnic minority adolescents relates to their academic, social, and psychological adjustment is an important and as yet unresolved research question. This study examined to what extent identifying with the heritage and/or host culture is an individual resource or risk factor for the adjustment of immigrant youth in Germany.

Background: Increasing attention is being paid to lifestyle factors, such as nutrition and physical activity (PA), as potential complementary treatment options in attention-deficit/hyperactivity disorder (ADHD). Previous research indicates that sugar and saturated fat intake may be linked to increased impulsivity, a core symptom of ADHD, whereas protein intake and PA may be related to reduced impulsivity. However, most studies rely on cross-sectional data that lack microtemporal resolution and ecological validity, wherefore questions of microtemporal dynamics (eg, is the consumption of foods high in sugar associated with increased impulsivity within minutes or hours?) remain largely unanswered.

Introduction: Adolescence is regarded as a formative period for political development. One important developmental context is media. Negatively perceived political media content can foster populistic attitudes, which in turn decreases support of political institutions, such as the European Union (EU).

In the last two decades, e-diary studies have gained increasing interest, with a dominant focus on mood and affect. Although requested in current guidelines, psychometric properties are rarely reported, and methodological investigations of factor structure, model fit, and the reliability of mood and affect assessment are limited. We used a seven-day e-diary dataset of 189 adolescent participants (12-17  years).

The goal of the present study was to investigate the effects of automatically generated, adaptive feedback on daily self-regulated learning (SRL) in an experimental field study. University students reported their application of SRL strategies in the morning and in the evening over the course of 36 days using electronic learning diaries. Students were randomly assigned to the experimental group with feedback (LDF,  = 98) or the control group without feedback (LD,  = 96).

Monocular eye patching modulates reorienting of covert attention in patients with unilateral middle cerebral artery stroke.

Brain Cogn

July 2023

Department of Psychology, School of Medicine and Health Sciences, Carl von Ossietzky University Oldenburg, Oldenburg, Germany; Department of Neurology, Klinikum Bremen-Ost, Bremen, Germany.

Unilateral brain lesions can lead to impaired contralesional attention and reduced ipsilesional and enhanced contralesional superior colliculus (SC) activity. We aimed to investigate whether modulation of SC activation via monocular eye patching can improve contralesional attention. Twenty left-hemispheric (LH) and 20 right-hemispheric (RH) patients with an acute or subacute middle cerebral artery (MCA) stroke completed an endogenous version of the Posner cueing task twice, while the left or right eye was covered with an eye patch.

Background: Affectionate touch, which is vital for mental and physical health, was restricted during the Covid-19 pandemic. This study investigated the association between momentary affectionate touch and subjective well-being, as well as salivary oxytocin and cortisol in everyday life during the pandemic.

Methods: In the first step, we measured anxiety and depression symptoms, loneliness and attitudes toward social touch in a large cross-sectional online survey (N = 1050).

Dysregulations of the hypothalamic-pituitary-adrenal (HPA) and sympatho-adrenal medullary (SAM) axis are associated with mental and somatic illness. However, there is lack of knowledge regarding the molecular mechanisms underlying these effects. Epigenetic states in the serotonin transporter gene (SLC6A4) were shown to be associated with stress in various forms.

As researchers in the social sciences, we are often interested in studying not directly observable constructs through assessments and questionnaires. But even in a well-designed and well-implemented study, rapid-guessing behavior may occur. Under rapid-guessing behavior, a task is skimmed shortly but not read and engaged with in-depth.

Empirical evidence suggests a great positive association between measures of fluid intelligence and working memory capacity, which implied to some researchers that fluid intelligence is little more than working memory. Because this conclusion is mostly based on correlation analysis, a causal relationship between fluid intelligence and working memory has not yet been established. The aim of the present study was therefore to provide an experimental analysis of this relationship.

Article Synopsis
  • Mental contrasting with implementation intentions (MCII) was tested to see if it could improve sleep outcomes compared to just providing sleep hygiene (SH) information.
  • The study involved 80 university employees who tracked their sleep and stress levels, finding that while overall sleep quality and duration improved, MCII didn't show a significant advantage over SH alone.
  • Higher stress was linked to poorer sleep quality and shorter sleep duration, suggesting that stress management might be key in improving sleep rather than simply using MCII techniques.

Digital studying in times of COVID-19: teacher- and student-related aspects of learning success in german higher education.

Int J Educ Technol High Educ

March 2023

Department for Higher Education, Institute of Educational Studies, Humboldt-Universität Zu Berlin, Unter Den Linden 6, 10099 Berlin, Germany.

Unlabelled: In the wake of COVID-19, study conditions in Europe have changed dramatically. To limit contact between students and teachers, since March 2020 teaching has largely taken place digitally (remotely via digital means) and in private. Because the success of digital learning likely relies on many factors beyond good digital infrastructure conditions, this article focuses on which aspects, at both the teacher and the student levels, promote digital learning success.

Working memory (WM) precision, or the fidelity with which items can be remembered, is an important aspect of WM capacity that increases over childhood. Why individuals are more or less precise from moment to moment and why WM becomes more stable with age are not yet fully understood. Here, we examined the role of attentional allocation in visual WM precision in children aged 8 to 13 years and young adults aged 18 to 27 years, as measured by fluctuations in pupil dilation during stimulus encoding and maintenance.

A photonic approach to the cancellation of self-interference in the optical domain with fiber dispersion immunity and harmonic frequency down-conversion function is proposed based on an integrated, dual-parallel, dual-drive Mach-Zehnder modulator (DP-DMZM). A dual-drive Mach-Zehnder modulator (DMZM) is used as an optical interference canceller, which cancels the self-interference from the impaired signal before fiber transmission to avoid the effect of fiber transmission on the cancellation performance. Another DMZM is used to provide carrier-suppressed, local-oscillation (LO)-modulated, high-order double optical sidebands for harmonic frequency down-conversion to release the strict demand for high-frequency LO sources.

Bayesian models allow us to investigate children's belief revision alongside physiological states, such as "surprise". Recent work finds that pupil dilation (or the "pupillary surprise response") following expectancy violations is predictive of belief revision. How can probabilistic models inform the interpretations of "surprise"? Shannon Information considers the likelihood of an observed event, given prior beliefs, and suggests stronger surprise occurs following unlikely events.

The affective tone of autobiographical memories may be influenced by age in two ways-by the current age of the remembering individual and by the age of the remembered self at the time of the remembered event. While aging has been associated with more positive autobiographical memories, young adulthood is remembered more positively than other parts of life. We tested whether these effects also show in life story memories and how they act jointly on affective tone; also, we wanted to explore their effects on remembered lifetimes other than early adulthood.

Background: The reciprocal internal/external frame of reference (RI/E) combines two models of academic self-concept formation, namely the reciprocal effects model (REM) and the internal/external frame of reference (I/E) model. The REM assumes reciprocal relations between achievement and academic self-concept. The I/E model assumes contrast effects between achievement and self-concept across math and verbal domains.

The transition to secondary school may negatively impact adolescents' psychosocial and subjective well-being development. However, how subjective well-being develops during secondary school and how school contextual factors, including aspects of ability grouping and achievement composition, are associated with the development of subjective well-being still require clarification. This study examined two measures of subjective well-being, life satisfaction and school satisfaction, to investigate the development of subjective well-being during secondary school.
