How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The perceptual span is a standard measure of parafoveal processing, which is
considered highly important for efficient reading. Is the perceptual span a stable indicator of reading performance? What drives its development? Do initially slower and faster readers converge or diverge over development? Here we present the first longitudinal data on the...
Gilbert et al. conclude that evidence from the Open Science Collaboration’s Reproducibility Project: Psychology indicates high reproducibility, given the study methodology. Their very optimistic assessment is limited by statistical misconceptions and by causal inferences from selectively interpreted, correlational data. Using the Reproducibility Pr...
Empirically analyzing empirical evidence
One of the central goals in any scientific endeavor is to understand causality. Experiments that seek to demonstrate a cause/effect relation most often manipulate the postulated causal factor. Aarts et al. describe the replication of 100 experiments reported in papers published in 2008 in three high-ranking...
On the one hand, facial electromyography (EMG) has been proven to indicate affective changes on the valence dimension (for a review, see Larsen et al., 2003) with high temporal precision. On the other hand, eyetracking allows for the exact measurement of visual attention allocation with high spatial and temporal precision. Hence, the time-synchrono...
Introduction
The Research Domain Criteria (RDoC) approach initiated by the National Institute of Mental Health provides a comprehensive framework for guiding research on mental illness and health. Since retrospective studies have indicated associations between RDoC characteristics and clinically relevant as well as care-relevant outcomes, there is...
Introduction
Care for people living with dementia is both important and complex, and there is evidence of large regional variations in the quality of care. This study protocol describes design, methods and objectives of an investigation of regional variations in the utilisation, the quality and the costs of care for people living with dementia in G...
Aging is a multi-organ disease, yet the traditional approach has been to study each organ in isolation. Such organ-specific studies have provided invaluable information regarding its pathomechanisms. However, an overall picture of the whole-body network (WBN) during aging is still incomplete. In this study, we analyzed the functional magnetic reson...
Aim of the study
To assess how the therapeutic relationship is perceived by therapists both in online and face-to-face therapy during the Covid-19 pandemic and if the therapist's personal, professional, and psychological characteristics, as well as their experience of the COVID-19 pandemic influence their perception of the therapeutic relationship....
Cognitive decline is associated with changes in EEG resting-state parameters. For instance, Alzheimer’s dementia (AD) is associated with a „slowing of the EEG“, as well as reduced alpha reactivity. While these measures were mostly established in group comparisons, to utilize these as biomarkers for individual diagnosis in memory clinics it would be...
What is the role of executive functions in longitudinally predicting reading success in general and perceptual-span size in particular? We present two new waves of our sequential-cohort longitudinal study of perceptual-span development, including five waves totally spanning grades 1 to 10. Using nonlinear mixed effects growth-curve modeling we here...
Background
Previous studies have shown that resting‐state electroencephalographic (rsEEG) and event‐related potential (ERP) biomarkers reflect the neurophysiological mechanisms underpinning vigilance dysfunctions and cognitive decline in persons with mild cognitive impairment (MCI) and dementia due to Alzheimer’s disease (ADD). However, their best...
Introduction
Online psychotherapy is a form of work that is becoming more and more popular. Public health problems, such as COVID-19, forced mental health professionals and patients to incorporate new methodologies such as the use of electronic media and internet to provide follow-up, treatment and also supervision. The aim of this study was to inv...
The perceptual span describes the size of the visual field from which information is obtained during a fixation in reading. Its size depends on characteristics of writing system and reader, but–according to the foveal load hypothesis–it is also adjusted dynamically as a function of lexical processing difficulty. Using the moving window paradigm to...
Higher-order cognitive skills are necessary prerequisites for reading and understanding words, sentences and texts. In particular, research on executive functions in the cognitive domain has shown that good executive functioning in children is positively related to reading comprehension skills and that deficits in executive functioning are related...
Morphologic and phylogenetic analysis of freshwater sponges endemic to lakes in Central Sulawesi, Siberia and South-East Europe is presented. We also analyzed several cosmopolitan sponge species from Eurasia and North America and included sponge sequences from public databases. In agreement with previous reports [Addis, J.S., Peterson, K.J., 2005....

Hi,
Imagine you have measured two variables X and Y at two points in time. You want to predict Y2 from X1 and also control for the autoregressive effect (= temporal stability) of Y1 and control for the correlation of X1 and Y1. My question: Is there any statistical reason that makes it necessary and/or advantageous to implement a full CLP, that is to include the pathes X1 -> X2, Y1 -> X2, and the correlation X2 <-> Y2?
I am not interested in reciprocal relations between X and Y. I just wonder whether including these additional pathes has an impact on my path of interest (X1 -> Y2) and if so, why? I'd also be glad if oyu could provide a reference.
Dear all,
I collected data from subjects in a longitudinal study. However, I now want to compare groups of persons in a cross-sectional fashion. My problem is that some subjects appear twice in the same group, because they were tested twice (1-year gap), while others appear only once in the group. While I am sure that it's problematic to analyse a subject twice if they were tested at the same time, I am not sure whether or why it is justifiable to analyse the person twice within the same group when he or she was tested at two different times.
Thanks for your help,
Johannes
