Deficits in the endogenous control of covert visuospatial attention in children with developmental coordination disorder

摘要: Abstract Deficits in the covert orienting of visuospatial attention have been reported children with Developmental Coordination Disorder (DCD). Using two new versions task (COVAT), study presented here sought to investigate how generalised deficits are this domain by using longer time intervals between cue and imperative stimulus. Twenty DCD 20 controls were tested on different COVATs interval peripheral stimulus (or onset asynchrony, SOA) 150 850 ms a random sequence: first used cues no probability information (exogenous mode) second central an 80% that stimuli would appear at cued location (endogenous mode). Results showed course was normal both groups. For cues, however, more disadvantaged invalid compared controls, regardless SOA; finding consistent deficit disengage operation directing attention. These results confirm extend our earlier impairments endogenous control exist DCD. PsycINFO classification: 2820; 2330; 2346; 3250
