Reconsidering Divergent and Convergent Thinking in Creativity – a Neurophysiological Index for the Convergence-Divergence Continuum
Creative problem-solving has been described as an iterative process of divergent and convergent modes of thinking. With this opinion paper, we illustrate how some tasks, commonly used for the neuroscientific investigation of creativity might provide a condensed representation of divergent and convergent thinking, respectively. We have identified the following reasons for this: The specific presentation of stimuli and response alternatives within …
Feel me, hear me
The visual sensory system is a well-researched system. While virtual reality (VR) is a predominantly visual experience, there is still the auditory and tactile aspects that can be considered. This study examines finding invisible static and dynamic targets in virtual reality with the help of vibrotactile and auditory cues. Using a ghost hunting setting, a game was developed to investigate the different types of cues as search indicators. The game…

Creative Activities Among Older Adults and People With Cognitive Impairment
Little is known about creativity in old age. The aim of this study was to investigate to what extent the intensity of engaging in creative activities differs between older and younger people as well as older people with and without cognitive impairment. Moreover, we evaluated associations of creative activities with specific cognitive abilities. For this cross‐sectional study, groups of younger people ( n = 24), older cognitively healthy people (…
Background music varying in tempo and emotional valence differentially affects cognitive task performance
The degree of stimulation provided by background music appears to affect performance on cognitive tasks. Moreover, individual differences influence what degree of stimulation is beneficial or detrimental. In a within-subject design, 40 participants (Mean Age: 26.15, SD: 2.99) completed cognitive tasks (immediate and delayed recall, phonemic fluency, trail-making) under varying (2 tempi: fast/slow×2 valences: positive/negative) musical background …
The right tools for the job
Virtual reality (VR) users interact with virtual objects using motion-tracked controllers. While many devices utilise abstract button pushes for interactions, some allow for limited finger tracking by estimating finger positions based on sensors. In this study, the Vive Wands and the Valve Index controllers were compared in three tasks: direct interaction with objects (throwing), tool usage (bow) and indirect control of a character (remote-contro…
The multiple-level framework of developmental dyslexia
Developmental dyslexia is a neurodevelopmental disorder characterized by an unexpected impairment in literacy acquisition leading to specific poor academic achievement and possible secondary symptoms. The multi-level framework of developmental dyslexia considers five levels of a causal pathway on which a given genotype is expressed and hierarchically transmitted from one level to the next under the increasing influence of individual learning-rele…
Developmental dyslexia and culture
Developmental dyslexia is recognized worldwide. However, there are cultural differences between countries in dyslexia-related issues, including assessment practices and intervention. Language and orthography are essential cultural factors that influence both literacy acquisition and the possible manifestation of developmental dyslexia. These differences in orthographies impose different culturally specific demands on cognitive processes involved …
Remote vocational learning opportunities—A comparative eye‐tracking investigation of educational 2D videos versus 360° videos for car mechanics
This study utilises a novel approach to investigate the effectiveness of different learning modalities by combining video‐based learning with eye‐tracking. An excerpt taken from a vocational education instruction for car mechanics was videotaped using two different cameras: a standard 2D video camera and a professional 360° camera. The video recorded with the 2D camera was presented on a tablet, with a fixed angle, whereas the video recorded with…
Differential Effects of Task-Irrelevant Monaural and Binaural Classroom Scenarios on Children’s and Adults’ Speech Perception, Listening Comprehension, and Visual–Verbal Short-Term Memory
Most studies investigating the effects of environmental noise on children's cognitive performance examine the impact of monaural noise (i.e., same signal to both ears), oversimplifying multiple aspects of binaural hearing (i.e., adequately reproducing interaural differences and spatial information). In the current study, the effects of a realistic classroom-noise scenario presented either monaurally or binaurally on tasks requiring processing of …
Processing emotional prosody in a foreign language
This study investigated the universality of emotional prosody in perception of discrete emotions when semantics is not available. In two experiments the perception of emotional prosody in Hebrew and German by listeners who speak one of the languages but not the other was investigated. Having a parallel tool in both languages allowed to conduct controlled comparisons. In Experiment 1, 39 native German speakers with no knowledge of Hebrew and 80 na…
Development of a Digital Video-Based Occupational Risk Assessment Method
The development and implementation of an observational video-based risk assessment is described. Occupational risk assessment is one of the most important yet also challenging tasks for employers. Most assessment tools to date use questionnaires, expert interviews, and similar tools. Video analysis is a promising tool for risk assessment, but it needs an objective basis. A video of a plastering worker was recorded using a 360° camera. The recordi…
Functional illiteracy and developmental dyslexia
A considerable amount of the population in more economically developed countries are functionally illiterate (i.e., low literate). Despite some years of schooling and basic reading skills, these individuals cannot properly read and write and, as a consequence have problems to understand even short texts. An often-discussed approach (Greenberg et al. 1997) assumes weak phonological processing skills coupled with untreated developmental dyslexia as…

Vocational Education and Training in the Age of Digitization
Effects of computerized grapho-phonological training on literacy acquisition and vocabulary knowledge in children with an immigrant background learning German as L2
As a consequence of globalization and migration, the number of children receiving literacy instruction in their second language (L2) is high and still increasing. Therefore, teachers need instruction methods that are effective in both L1 and L2 learners. Here, we investigate the effectiveness of a computerized training program combining phoneme perception, phonological awareness, and systematic phonics, in a sample of second-graders (N = 26) inst…

First and Second Language Acquisition in German Children Attending a Kindergarten Immersion Program
This study investigated first (L1) and second (L2) language acquisition in two age-matched groups of 2- to 6-year-old kindergarten children over the course of 2.5 years. The immersion group participated in a partial English immersion program whereas the conventional instruction group received a conventional L2 course (30 minutes per week); the groups were comparable with respect to control variables (e.g., socioeconomic status). L1 and L2 compete…
Goodness is central
We adopted the psychological refractoriness paradigm to study whether visual pattern goodness affects central processing load in a same‐different task. In a dual‐task experiment, a two‐alternative forced choice auditory classification was followed by a same‐different task in which Garner's classical five‐dot patterns were presented. Goodness of these patterns and stimulus‐onset asynchrony (SOA) between the first and second task were varied betwee…
