To write by hand, to type, or to draw – which of these strategies is the most efficient for optimal learning in the classroom? As digital devices are increasingly replacing traditional writing by hand, it is crucial to examine the long-term implications of this practice. High-density electroencephalogram (HD EEG) was used in 12 young adults and 12,...
Article
According to traditional linguistic theories, the construction of complex meanings relies firmly on syntactic structure-building operations. Recently, however, new models have been proposed in which semantics is viewed as being partly autonomous from syntax. In this paper, we discuss some of the developmental implications of syntax-based and autono...
Preprint
Abstract submission for the 2020 BCI Meeting by the BCI Society. The ability to correctly assess a rapidly approaching "looming" object is a deciding factor for survival. The responsible perceptual neural mechanisms start to develop during early infancy, and the onset of self-produced locomotion boosts this development. Preterm infants are at ris...
Article
A fundamental property of most animals is the ability to see whether an object is approaching on a direct collision course and, if so, when it will collide. Using high-density electroencephalography in infants and a looming stimulus approaching under three different accelerations, we previously found how visual information for impending collision i...

Article
A virtual object approaching on a collision course will elicit defensive blinking in infants. Previous research has shown that when precisely timing their blinks, full-term infants shift from using a strategy based on visual angle/angular velocity to a strategy based on time between 22 and 30 weeks of age. To investigate which timing strategy prete...

The ability to correctly asses a rapidly approaching, respectively looming object is a deciding factor for survival. The therefore responsible perceptual neural mechanisms start to develop during infancy. With the onset of locomotion this development is propelled in healthy infants. Preterm infants whether are at risk of having perceptuo-motor deficits, and often show an impairment in assessing and responding to visual motion. Thus, early diagnosis and a subsequent intervention could help to minimize the effects of this impairment and therefore increase their later quality of life (Agyei, van der Weel and van der Meer, 2016). By using the looming-related visual evoked potential (VEP) to classify the infant’s performance online, an early diagnosis can be facilitated.
