Description
As part of the CRAB (Computerized Reading-related Assessment Battery), the Barrage task assesses selective visual attention by requiring participants to identify and select target symbols among distractors within a fixed symbol array. This digital-based task targets visual search efficiency and attentional selectivity, for which associations with reading-related cognitive skills have been reported in the developmental literature.
