INTROZZI, Isabel et al. The development mechanisms of selective attention in child population. CES Psicol [online]. 2019, vol.12, n.3, pp.105-118. ISSN 2011-3080.  https://doi.org/10.21615/cesp.12.3.8.

Selective attention allows directs attention to relevant objects or stimuli, while avoiding distraction from those that are irrelevant. The literature indicates that performance in CVS tasks improves markedly with age. However, age-related differences are not met neither for every number of distractor conditions nor for all age groups. In addition, the contribution of inhibitory control and processing speed to this progressive improvement has not yet been explored. For this reason, and due to the scarcity of studies using CVS paradigm to evaluate selective attention in children, the present study aimed to analyze the relative contribution of processing speed and inhibition to performance during this evolutionary period in a selective attention and CVS task. To do this, a CVS and a simple response speed task were administered to 295 children aged 6-13 years old. Results offered two conclusions: first, selective attention improves during childhood; second, there is no general and exclusive mechanism capable of explaining these differences during this period. Thus, both processing speed and inhibitory control contribute to development of selective attention, and they seem to be more complementary mechanisms than excluding ones.
