A flexible framework for simulating and fitting generalized drift-diffusion models
The drift-diffusion model (DDM) is an important decision-making model in cognitive
neuroscience. However, innovations in model form have been limited by methodological …

Differentiating between integration and non-integration strategies in perceptual decision making
Many tasks used to study decision-making encourage subjects to integrate evidence over
time. Such tasks are useful to understand how the brain operates on multiple samples of …

Racing against the clock: Evidence-based versus time-based decisions.
GE Hawkins, A Heathcote - Psychological Review, 2021 - psycnet.apa.org
Classical dynamic theories of decision making assume that responses are triggered by
accumulating a threshold amount of information. Recently, there has been a growing …

Visual motion and decision-making in dyslexia: Reduced accumulation of sensory evidence and related neural dynamics
Children with and without dyslexia differ in their behavioral responses to visual information,
particularly when required to pool dynamic signals over space and time. Importantly …

Urgency, leakage, and the relative nature of information processing in decision-making.
Over the last decade, there has been a robust debate in decision neuroscience and
psychology about what mechanism governs the time course of decision-making. Historically …

Behavioural and neural indices of perceptual decision-making in autistic children during visual motion tasks
Many studies report atypical responses to sensory information in autistic individuals, yet it is
not clear which stages of processing are affected, with little consideration given to decision …

The role of passing time in decision-making.
Theories of perceptual decision making have been dominated by the idea that evidence
accumulates in favor of different alternatives until some fixed threshold amount is reached …

Not all speed-accuracy trade-off manipulations have the same psychological effect
In many domains of psychological research, decisions are subject to a speed-accuracy trade-
off: faster responses are more often incorrect. This trade-off makes it difficult to focus on one …

Modeling distracted performance
The sustained attention to response task (SART) has been the primary method of studying
the phenomenon of mind wandering. We develop and experimentally test the first integrated …

Decision urgency invigorates movement in humans
D Thura - Behavioural brain research, 2020 - Elsevier
Recent work in highly trained monkeys suggests that decision-making and motor control are
linked processes whose regulation by urgency allows reward rate optimization. However …
