The flexible listener: exploring zebra finch sensitivity to spectral and temporal sound features
Human vocal communication and music perception represent advanced cognitive skills, seemingly innate and universal. These faculties encompass a range of perceptual and cognitive abilities. Cross-species research sheds light on the origins of musicality by investigating whether these traits are shared…

De mentaliteit van de overheid hindert burgerinitiatieven
De wijze en instelling waarop de overheid burgerinitiatieven ondersteunt, zijn vaak belangrijker dan het juridische kader. Het levert in de praktijk alleen maar onnodige tweedeling op en er is geen solide basis voor. Dit is één van de conclusies van het proefschrift van Esmée Driessen, promovenda bij…
