Microsaccades are disrupted in various neurological disorders, including ADHD, schizophrenia, and Parkinson's disease, resulting in gaze instability during fixation. In ADHD, individuals show increased microsaccade rates and unstable gaze, which may improve with medication.
Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD.Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training ...
The time interval in between the onset of the cue and the onset of the target is defined as the stimulus onset asynchrony (SOA). Previous studies using this spatial cueing task found that in addition to cue validity, behavioural reactions were also affected by SOA. The effect of the SOA varies depending on whether a central or peripheral cue is ...
Attention deficit hyperactivity disorder; Other names: Formerly: Attention deficit disorder (ADD), hyperkinetic disorder (HD) [1]: ADHD arises from maldevelopment in brain regions such as the prefrontal cortex, basal ganglia and anterior cingulate cortex, which regulate the executive functions necessary for human self-regulation.
In both children and adults with ADHD, an underlying executive dysfunction involving the prefrontal regions and other interconnected subcortical structures has been found. [55] As a result, people with ADHD commonly perform more poorly than matched controls on interference control, mental flexibility and verbal fluency.
The T.O.V.A. has been shown to accurately identify 87% of individuals without ADHD, 84% of non-hyperactive ADHD, and 90% of the hyperactive ADHD, but should never be used solely as a diagnostic tool for those testing for attention deficit disorders or with a traumatic brain injury.
A hyperfixation can also come be related to executive functioning issues, Adler says, which can make time management and decision-making challenging — especially during times of stress.
Representation of the stages of processing in a typical reaction time paradigm. Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations.
