To test the hypothesis that a higher tendency to "s"pontaneously "f"ocus "o"n "m"ultiplicative "r"elations (SFOR) leads to improvements in rational number knowledge via more exact estimation of fractional quantities, we presented sixth graders (n = 112) with fraction number line estimations and a…

In the present study, the assumption was tested that expectancy-incongruent feedback in conjunction with explicit self-affirmation directs attention away from the task and to the self. As a result, performance should decrease in resource-sensitive text/picture comprehension tasks as compared to resource-insensitive tasks. Three hundred and…

At school, pupils often cooperate on common projects and must coordinate their different individual actions. However, grades are pervasively used even in cooperative situations, which make the pupils' differences in achievement and their relative rank salient and may reduce their inclination to work constructively with others. Thus, we…

This study assessed the effects of a best friend's facial attractiveness on first impressions of medium-attractive children and early adolescents. Younger (N = 114, 48 boys and 66 girls, M[subscript age] = 8.16 years) and older (N = 168, 83 boys and 85 girls, M[subscript age] = 12.32 years) participants rated photos of unknown medium-attractive…

The study investigated the influence of geographical location, gender and age on the performance of Piagetian Conservation tasks. Four conservation tasks; conservation of liquid, length, substance amount and number respectively were administered to children [4-6 years] from rural and urban Ghana and their performance on each task were recorded.…

An implicit word learning paradigm was designed to test the hypothesis that children who came to the task of L2 vocabulary acquisition with poorer L1 phonological awareness (PA) are less capable of extracting phonological patterns from L2 and thus have difficulties capitalizing on this knowledge to support L2 vocabulary learning. A group of…

Do concrete learning materials promote strong learning outcomes, or do they simply make learning tasks more initially accessible? Although concrete materials may offer an intuitive foothold on a topic, research on desirable difficulties suggests that more challenging tasks facilitate greater retention and transfer. In the approach introduced here,…

Deaf Children usually achieve lower scores on numerical tasks than normally hearing peers. Explanations for mathematical disabilities in hearing children are based on quantity representation deficits (Geary, 1994) or on deficits in accessing these representations (Rousselle & Noël, 2008). The present study aimed to verify, by means of symbolic…

The purpose of this study was to test the hypothesis that word reading accuracy, not oral language, is associated with spelling performance in school-age children. We compared fourth grade spelling accuracy in children with specific language impairment (SLI), dyslexia or both (SLI/dyslexia) to their typically developing grade-matched peers.…

Previous research has found a link between theory of mind and cooperation. The aim of this study is to deepen into this relationship, to identify which theory of mind skills are more related to the cooperative ability on a referential communication task. A total of 50 children from first and fifth grade completed a battery of theory of mind tasks,…

The present study tested the hypothesis of the cognitively competent but morally insensitive bully. On the basis of teacher and peer ratings, 212 young elementary school children were selected and categorized as bullies, bully-victims, victims, and prosocial children. Children's perspective-taking skills were assessed using theory-of-mind tasks,…
