Attentional Performance, Age and Scholastic Achievement in Healthy Children

Attentional processes in children play a critical role in daily school demands and accomplishments. Studies on the association of attentional processes with school achievement and age in healthy school children are scarce. The aim of the present study was to identify correlations between dimensions of attentional performance, scholastic achievement and age.An extensive testing battery was used to assess a wide range of attentional dimensions. A principal component analysis revealed three factors that are related to attentional performance (distractibility, lapses of attention, cognitive speed). Age was negatively associated with distractibility, lapses of attention and cognitive speed, indicating that distractibility and lapses of attention decreased with age in healthy children and resulted in lower cognitive speed.Attentional processes in healthy children should be measured in relation to distractibility, lapses of attention and cognitive speed

Assessment of Cognitive Outcome Measures in Teenagers with 15q13.3 Microdeletion Syndrome

15q13.3 microdeletion syndrome causes a spectrum of cognitive disorders, including intellectual disability and autism. We aimed to determine if any or all of three cognitive testing systems (the KiTAP, CogState, and Stanford–Binet) are suitable for assessment of cognitive function in affected individuals. These three tests were administered to ten individuals with 15q13.3 microdeletion syndrome (14–18 years of age), and the results were analyzed to determine feasibility of use, potential for improvement, and internal consistency. It was determined that the KiTAP, CogState, and Stanford–Binet are valid tests of cognitive function in 15q13.3 microdeletion patients. Therefore, these tests may be considered for use as objective outcome measures in future clinical trials, assessing change in cognitive function over a period of pharmacological treatment
