Abstract
Objective: To investigate whether adults with ADHD show pseudoneglect - preferential allocation of attention to the left visual field (LVF) and a resulting slowing of mean reaction times (MRT) in the right visual field (RVF), characteristic of neurotypical individuals (NT) - and whether lateralization of attention is modulated by presentation speed and incentives.
Method: Fast Task, a 4-choice reaction-time task where stimuli were presented in LVF or RVF, was used to investigate differences in MRT and reaction time variability (RTV) in adults with ADHD (n = 43) and NT (n = 46) between a slow/no-incentive and fast/incentive condition. In the lateralization analyses pseudoneglect was assessed based on MRT, which was calculated separately for the LVF and RVF for each condition and each study participant.
Results: Adults with ADHD had overall slower MRT and increased RTV relative to NT. MRT and RTV improved under the fast/incentive condition. Both groups showed RVF-slowing with no between-group or between-conditions differences in RVF-slowing.
Conclusions: Adults with ADHD exhibited pseudoneglect, a neurotypical pattern of lateralization of attention, which was not attenuated by presentation speed and incentives.
