23 March and 14 April 2022 - Understanding the brain through the eyes
What we see and how we see can be used to help us understand how the brain works. Illusions are not just visual tricks, but illustrate the deep principles which our brains use to construct reality. In this talk, with the use of many examples, I will show how the study of illusions provides important lessons for psychologists trying to understand all aspects of mind, brain and behaviour

16 June 2021 - Why you should use decision models with your response time and accuracy data at Centre for Cognition and Neuroscience, University of Huddersfield (and online).
Decision modelling is increasingly accessible and yields highly practical benefits to experimental psychologists. This talk will explain why and how you should apply decision models to your data.
Response time and accuracy are fundamental measures of behavioural science, but discerning participants' underlying abilities can be masked by speed-accuracy trade-offs (SATOs). SATOs are often inadequately addressed in experiment analyses which focus on a single variable or which involve a suboptimal analytic correction. Models of decision making, such as the drift diffusion model (DDM), provide a principled account of the decision making process, allowing the recovery of SATO-unconfounded decision parameters from observed behavioural variables.
I will show, using simulations and worked examples from experimental data, how decision models allow potentially massive increases in statistical power at the same time as helping you avoid mistaken inferences due to variations in participants' SATOs strategies. Because the modelling community has focussed on differences between different decision models, this has disguised the fact that there is now a consensus around the core mechanisms which define the family of plausible decision models, as well as increasing agreement on tools for fitting behavioural data with these decision models.
