In Search for a Decolonizing Actor: Contradictions Between Brazilian State Policies and Social Emancipation of Quilombolas
(2018)
This paper explores the articulations between the present social struggles of Quilombolas (Maroons’ descendants of those who escaped enslavement), state policies, coloniality and global inequality. Two case studies illustrate how the infiltration of global mining and overexploitation of eucalyptus have diminished natural resources in the region and encroached upon the land rights of black communities. This paper first provides a comprehensive review of the policy changes that paved the way for the recognition of the ...

The legitimation of expulsion in development discourse. A comparative analysis of World Bank projects in sub-Saharan Africa
(2019)
Comparing examples from Kenia, Ethiopia and Nigeria, the article examines how displacement through infrastructure projects is being legitimised in development discourse. Three typical justifications are the inevitability of progress, the greater common good and property rights. They are closely linked to elements of development discourse: the transformation of geocultural differences into historical stages, Othering of allegedly backward peoples, the concept of trusteeship and the assumption of the beneficial effects ...

Partnership and cooperation in Haiti: Clashes of reality and construction
(2016)
This paper analyses existent and perceived rules and restrictions of the global development dispositif working to maintain inequalities in interactions of International NGOs (INGOs) and Haitian organisations. It does so by exploring constructions of partnership and their clashing realities. Development organisations and agencies have influenced the fabric of Haitian society and politics not only by their mere presence but also by the rules they impose. The paper approaches this by identifying positions of power and ...

The World Bank Inspection Panel and civil society protest: Glocalization of accountability? The case of the Kwabenya landfill project in Ghana
(2015)
20 years ago, the Inspection Panel was founded as a mechanism of accountability for people negatively affected by projects funded by the World Bank. It allows them to call for an investigation if social and environmental standards of the World Bank have not been adhered to and. Its origin can be traced back to pressure exerted by a transnational NGO campaign on US congress in the wake of the Narmada Valley Development Project. While the Panel’s history since then shows that it usually does not have the power to ...

Wünschenswerte Erschwernisse beim Lernen
(2015)
Der Beitrag beleuchtet didaktische Maßnahmen, die unter dem Begriff „Wünschenswerte Erschwernisse“ zusammengefasst werden. Diese Maßnahmen erschweren zwar kurzfristig das Lernen, langfristig aber fördern sie das Behalten und den Transfer des Gelernten. Vier dieser wünschenswerten Erschwernisse sind empirisch besonders gut belegt: 1) Das verteilte Lernen, 2) das verschachtelte Lernen, 3) der Testungseffekt und 4) der Generierungseffekt. Zu jeder dieser wünschenswerten Erschwernisse werden aktuelle Forschungsergebnisse ...

Girls in detail, boys in shape: Gender differences when drawing cubes in depth
(2013)
The current study tested gender differences in the developmental transition from drawing cubes in two‐ versus three dimensions (3D), and investigated the underlying spatial abilities. Six‐ to nine‐year‐old children (N = 97) drew two occluding model cubes and solved several other spatial tasks. Girls more often unfolded the various sides of the cubes into a layout, also called diagrammatic cube drawing (object design detail). In girls, the best predictor for drawing the cubes was Mental Rotation Test (MRT) accuracy. ...

Shape But Not Color Facilitates Two-Year-Olds’ Search Performance in a Spatial Rotation Task
(2018)
Children younger than 3 years of age often fail to track hidden objects that are rotated together with identical hiding containers, which might be due to relatively complex paradigms. We examined whether 2-year-olds (N = 28) are already able to track spatial rotations (i.e., by 90° and 180°) if the task is facilitated by increasing the visual discriminability of the hiding containers by means of different shapes and different colors. Children performed above chance level in all conditions except for the condition in ...

Let’s twist again! Embodiment effects in spatial judgments on human figures rotated along a vertical axis
(2017)
We investigated whether individuals used mental rotation and embodiment for arm laterality judgments of human figures that were stepwise rotated from back view to front view along a vertical axis. In Experiment 1, figures’ heads were always shown in profile, while only the bodies were rotated. Judgments were faster and more correct when figures were presented in back view compared to front view, but the relation between reaction times (RTs) and rotation angles was not strictly linear. In addition, judgments on figures ...

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds
(2015)
Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence ...
