Primi et al. The Early Elementary School-AMAS We have also demonstrated the equivalence of the scale across languages (Italian and English). Overall, the findings confirmed the validity and reliability of the new scale in assessing the early signs of math anxiety and in measuring differences between genders and educational contexts. We have also shown that MA was already related to math performance, and teacher's ratings of children's math ability at this young age. Additionally, we have found no gender differences in MA in our samples of 6-and 7year-old children, an important finding, given the strong evidence for gender differences in MA in older age groups.

The mediation model provided the best fitting and more parsimonious representation of the relations between body weight, stigma experiences, and HRQoL, meaning that an increased likelihood of experiencing weight-based teasing episodes, rather than excess weight per se, is associated with reduced quality of life in middle childhood.

Orbitofrontal reality filtering denotes a memory control mechanism necessary to keep thought and behavior in phase with reality. In adults, it is mediated by the orbitofrontal cortex and subcortical connections and its failure induces reality confusion, confabulations, and disorientation. Here we investigated for the first time the development of this mechanism in 83 children from ages 7 to 11 years and 20 adults. We used an adapted version of a continuous recognition task composed of two runs with the same picture set but arranged in different order. The first run measures storage and recognition capacity (item memory), the second run measures reality filtering. We found that accuracy and reaction times in response to all stimulus types of the task improved in parallel across ages. Importantly, at no age was there a notable performance drop in the second run. This means that reality filtering was already efficacious at age 7 and then steadily improved as item memory became stronger. At the age of 11 years, reality filtering dissociated from item memory, similar to the pattern observed in adults. However, performance in 11-year-olds was still inferior as compared to adults. The study shows that reality filtering develops early in childhood and becomes more efficacious as memory capacity increases. For the time being, it remains unresolved, however, whether this function already depends on the orbitofrontal cortex, as it does in adults, or on different brain structures in the developing brains of children.
