Most studies have concentrated in assessing students' overall attitudes towards science, mathematics, and engineering/technology or the attitude towards individual STEM domain. The present research aims to explore primary students' gender and grade differences of their STEM domain-specific attitudes including self-efficacy and expectancy-value…

Masked priming studies have shown that readers decompose morphologically complex words ("read+er"). Interindividual differences have been suggested to affect this phenomenon. However, its development is poorly understood. We addressed this issue by taking a longitudinal approach that allows greater rigor in establishing the relationship…

Background: Students with intellectual disabilities (IDs) have various learning difficulties and are at risk for school failure. Large inter-individual differences are described for reading, but it is unclear how these vary as a function of grade.
