Background Intraindividual variability in reaction time (RT) has received extensive
discussion as an indicator of cognitive performance, a putative intermediate phenotype of …

Attention-deficit/hyperactivity disorder (ADHD) is among the many syndromes in the
psychiatric nosology for which etiological signal and clinical prediction are weak. Reducing …

Efficient information processing facilitates cognition and may be disrupted in a number of
neurodevelopmental conditions. And yet, the role of inefficient information processing and its …

Importance Psychiatric nosology is limited by behavioral and biological heterogeneity within
existing disorder categories. The imprecise nature of current nosologic distinctions limits …

The diffusion model (Ratcliff,) takes into account the reaction time distributions of both
correct and erroneous responses from binary decision tasks. This high degree of information …

Objective Performance accuracy and reaction time in cognitive tasks are routinely used to
evaluate the efficacy of tDCS to affect cognitive task performance. tDCS alters the excitability …

Objective Understanding the role of endophenotypes is essential for process models of
psychopathology. This study examined which candidate cognitive endophenotypes …

In contrast to historical conceptualizations that framed psychological disorders as distinct,
categorical conditions, it is now widely understood that co-and multi-morbidities between …

Attention deficit hyperactivity disorder (ADHD) is characterized by altered decision-making
(DM) and reinforcement learning (RL), for which competing theories propose alternative …

Using Ratcliff's diffusion model and ex-Gaussian decomposition, we directly evaluate the
role individual differences in reaction time (RT) distribution components play in the …
