A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive abilities unfold. The reported study investigates children's data from three linguistic groups (179 sequential bilingual, 96 simultaneous bilingual and 57 monolingual German-speaking children) and examines differences (1) regarding cognitive outcome measures pertaining to selective attention, visuospatial thinking and abstract thinking and (2) searches for substantial developmental trajectory differences regarding said measures. Children were tested at 3 points in time; at age 4;10, 6;2 and 7;4. Results indicate no significant linguistic group differences in selective attention, visuospatial thinking and abstract thinking when controlling for gender, language comprehension of the child, and families' socioeconomic status. Moreover, the three linguistic groups did not differ in developmental trajectories. Theoretical and practical implications are discussed.
