Inclusion criteria

Inclusion criteria: Children (term born n=23; preterm n=10) who were previously investigated on their development of visual attention in 2000-2002. We refer to the research protocol of S. Hunnius for the original inclusion criteria.

Exclusion criteria

Exclusion criteria: Children are excluded when they are not traceable (lost to follow-up), or when the parents and/or their child refuse participation.

Design outcomes

Primary

Measure	Time frame
Early visual attention was expressed in: - duration of holding attention (fixation of gaze); - the time it takes to shift attention from a central stimulus to a peripheral stimulus and visa versa. The main endpoints of this study are derived from: - validated neuropsychological tests and parental questionnaires, to be expressed in percentiles and z-scores; - experimental tasks, to be expressed in average response times and number of correct answers. Because of lacking of standardized data, experimental test results of term born children will be compared with that of preterm children.	—
