ParAcT-DDM: A diffusion-based framework for modelling systematic, time-varying cognitive processes Open
As people engage in tasks over extended periods, their psychological states systematically change due to factors, such as practice, learning, and/or boredom. However, the dominant frameworks for modelling cognitive processes – such as evid…

Parameter estimation of hyper-spherical diffusion models with a time-dependent threshold: An integral equation method Open
Over the past several decades, decision-making research has been dominated by the study of binary choice tasks, with key models assuming that people remain equally cautious regardless of how long they have spent on the choice problem. Rece…

Deciding with muscles Open
Sequential sampling models have a rich tradition in psychology, and play a central role in our understanding of human decision-making. According to these models, decisions arise from the gradual accumulation of noisy evidence over time unt…

Attention to direct gaze in young and older adulthood Open
Attention to others' direct gaze supports many social-cognitive processes (e.g., emotion recognition, joint attention) that are known to decline with age, but it remains to be established whether attention to direct gaze itself is associat…

People are at least as good at optimizing reward rate under equivalent fixed-trial compared to fixed-time conditions Open
Finding an optimal decision-making strategy requires a careful balance between the competing demands of accuracy and urgency. In experimental settings, researchers are typically interested in whether people can optimise this trade-off, typ…

An Expert Guide to Planning Experimental Tasks For Evidence-Accumulation Modeling Open
Evidence-accumulation models (EAMs) are powerful tools for making sense of human and animal decision-making behavior. EAMs have generated significant theoretical advances in psychology, behavioral economics, and cognitive neuroscience and …

Perceptual decision-making in autistic and non-autistic adults and relationship with autism- and ADHD-related traits Open
Autistic individuals respond to sensory information in perceptual tasks differently than non-autistic individuals. However, it is unclear which component processes are altered, and how other aspects of neurodiversity (e.g., ADHD traits) af…

An evaluation of online information acquisition in US news deserts Open
A growing concern is that as local newspapers disappear, communities lose trusted gatekeepers and develop information voids, creating openings for misinformation to thrive. Previous work has not evaluated whether residents of news deserts …

The value of error-correcting responses for cognitive assessment in games Open
Traditional conflict-based cognitive assessment tools are highly behaviorally restrictive, which prevents them from capturing the dynamic nature of human cognition, such as the tendency to make error-correcting responses. The cognitive gam…

Potential mental health-related harms associated with the universal screening of anxiety and depressive symptoms in Australian secondary schools Open
Background Anxiety and depressive disorders typically emerge in adolescence and can be chronic and disabling if not identified and treated early. School-based universal mental health screening may identify young people in need of mental he…

The gated cascade diffusion model: An integrated theory of decision making, motor preparation, and motor execution. Open
This article introduces an integrated and biologically inspired theory of decision making, motor preparation, and motor execution. The theory is formalized as an extension of the diffusion model, in which diffusive accumulated evidence fro…

Uncovering the cognitive mechanisms underlying the gaze cueing effect Open
The gaze cueing effect is the tendency for people to respond faster to targets appearing at locations gazed at by others, compared with locations gazed away from by others. The effect is robust, widely studied, and is an influential findin…

An Extension of the Shifted Wald Model of Human Response Times: Capturing the Time Dynamic Properties of Human Cognition Open
Despite the ubiquitous nature of Evidence Accumulation Models in cognitive and experimental psychology there has been a comparatively limited uptake of such techniques in the applied literature. While quantifying latent cognitive processin…

Does allowing for changes of mind influence initial responses? Open
Evidence accumulation models (EAMs) have become the dominant theoretical framework for rapid decision-making, and while many theoretically distinct variants exist, comparisons have proved challenging due to strong mimicry in their predicti…

Numerical Approximation of the First-Passage Time Distribution of Time-Varying Diffusion Decision Models: A Mesh-Free Approach Open
Sequential sampling theory is the dominant theoretical framework for explaining human decision making behavior. In this theory, the decision process is determined by a stochastic process in a bounded domain, with the likelihood function of…

Race Lévy flights: A mathematically tractable framework for studying heavy-tailed accumulation noise Open
Lévy flights is a particular exemplar of the generalised random walk processes, in which the jump lengths are drawn from a power-law asymptote ($\alpha$-stable) distribution. While employing this heavy-tailed distribution for accumulation …

A diffusion model decomposition of motion processing performance in children with dyslexia and related neural dynamics Open
Children with dyslexia have elevated psychophysical thresholds in global motion tasks. However, threshold estimates conflate multiple processes so it is unclear which processing stages are altered in dyslexia. The drift-diffusion framework…

Behavioural and neural indices of perceptual decision-making in autistic children during visual motion tasks Open
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-making processes. We combined diffusion modelli…
