Understanding cognitive changes in children aged 7 to 10

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to explore cognitive variability in children aged 7 to 10 by employing advanced methodologies such as experience sampling, longitudinal designs, and deep phenotyping. It seeks to answer key questions regarding individual differences in cognitive performance, the underlying neural and environmental factors, and the long-term implications of these cognitive variations. By integrating various statistical approaches, the study will provide insights into how cognitive abilities develop and differ among children over time.

Exclusion Criteria:

* A potential subject will be excluded from participation in the study if the participant indicates not understanding the instructions of the behavioural tasks due to a language barrier. In the imaging arm of the study, a potential subject who meets any of the following criteria will further be excluded from participation in the imaging arm of the study:

  * History of neurological or psychiatric illness.
  * History of using psychotropic medications.
  * Contraindications for MRI.
  * Metal parts that cannot be removed, are present in or on upper body, e.g. plates, screws, aneurysm clips, metal splinters, piercings or medical plasters. (exception: dental fillings, crowns, a metal wire behind the teeth, tattoos and contraceptive coils).
  * Body containing metal fragments, in particular in the eye, e.g., caused by injuries when working with metal.
