Tasks are sorted according to adults’ loadings. Children’s loadings follow a qualitatively similar pattern. Abbreviations: Enum = Enumeration; Spat.Span = Spatial Span; UFOV = Useful Field of View; MOT = Multiple Object Tracking; PDMS = Position Delayed Match-to-Sample; CD = Change Detection; PPVT = Peabody Picture Vocabulary Test; ANT alert = Attention Network Task alerting score; ANT conflict = Attention Network Task conflict score; CD filter = Change detection with distracting items; CDMS = Color Delayed Match-to-Sample; ODMS = Orientation Delayed Match-to-Sample
