Tasks are sorted according adults’ correlations. “PCA rank” refers to the ordering, from Table 1, of adults' first-component task loadings. Thresholds for statistical significance, at alpha = .05, are r = 0.304 (children) and r = 0.219 (adults). Abbreviations: Spat.Span = Spatial Span; Enum = Enumeration; MOT = Multiple Object Tracking; PDMS = Position Delayed Match-to-Sample; ANT alert = Attention Network Task alerting score; UFOV = Useful Field of View; CD = Change Detection; PPVT = Peabody Picture Vocabulary Test; ANT conflict = Attention Network Task conflict score; ODMS = Orientation Delayed Match-to-Sample; CD filter = Change detection with distracting items; CDMS = Color Delayed Match-to-Sample
