Brief summary
Exploring the non-symbolic and symbolic arithmetic competencies in two groups of children (5-, and 7-year-olds). Additionally, we explored the relationship with domain-general factors such as inhibition and attention. Recorded fMRI.
Detailed description
Using T2\*-weighted eip imaging, we measured BOLD response in two cohorts of healthy children while they were doing different cognitive tasks in the scanner. These tasks included solving non-symbolic (i.e. sets of elements) and symbolic (i.e. Arabic digits) addition and subtraction problems, a color control task, an attentional task measuring different facets of spatial attention, and a task measuring inhibition. We also recorded a high-resolution anatomical scan of the brain.
Interventions
no intervention in a medical sense, only observing changes of BOLD signal during different experimental conditions in cognitive tasks (arithmetic, attention, inhibition)
