A flexible framework for simulating and fitting generalized drift-diffusion models

M Shinn, NH Lam, JD Murray - ELife, 2020 - elifesciences.org
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

GM Stine, A Zylberberg, J Ditterich, MN Shadlen - Elife, 2020 - elifesciences.org
Many tasks used to study decision-making encourage subjects to integrate evidence over

Racing against the clock: Evidence-based versus time-based decisions.

GE Hawkins, A Heathcote - Psychological Review, 2021 - psycnet.apa.org

Urgency, leakage, and the relative nature of information processing in decision-making.

JS Trueblood, A Heathcote, NJ Evans… - Psychological …, 2021 - psycnet.apa.org
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

C Manning, CD Hassall, LT Hunt, AM Norcia… - Scientific reports, 2022 - nature.com
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 …

Not all speed-accuracy trade-off manipulations have the same psychological effect

D Katsimpokis, GE Hawkins, L van Maanen - Computational Brain & …, 2020 - Springer
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
