The timing mega-study: comparing a range of experiment generators, both lab-based and online (2020)
Journal Article

Many researchers in the behavioral sciences depend on research software that presents stimuli, and records response times, with sub-millisecond precision. There are a large number of software packages with which to conduct these behavioural experimen...

PsychoPy2: experiments in behavior made easy (2019)
Journal Article

PsychoPy is an application for the creation of experiments in behavioral science (psychology, neuroscience, linguistics, etc.) with precise spatial control and timing of stimuli. It now provides a choice of interface; users can write scripts Python i... Read More about PsychoPy2: experiments in behavior made easy.

Target meta-awareness is a necessary condition for physiological responses to masked emotional faces: Evidence from combined skin conductance and heart rate assessment (2017)
Journal Article

© 2017 Elsevier Inc. Much heated debate surrounds the extent to which we can process emotional stimuli without awareness. In particular the extent to which masked emotional faces can elicit changes in physiology measurements, such as heart rate and s...

Measuring nonlinear signal combination using EEG (2017)
Journal Article

Relatively little is known about the processes, both linear and nonlinear, by which signals are combined beyond V1. By presenting two stimulus components simultaneously, flickering at different temporal frequencies (frequency tagging) while measuring...

Cue Combination of Conflicting Color and Luminance Edges (2015)
Journal Article

Abrupt changes in the color or luminance of a visual image potentially indicate object boundaries. Here, we consider how these cues to the visual “edge” location are combined when they conflict. We measured the extent to which localization of a compo... Read More about Cue Combination of Conflicting Color and Luminance Edges.

Luminance cues constrain chromatic blur discrimination in natural scene stimuli (2013)
Journal Article

Introducing blur into the color components of a natural scene has very little effect on its percept, whereas blur introduced into the luminance component is very noticeable. Here we quantify the dominance of luminance information in blur detection an... Read More about Luminance cues constrain chromatic blur discrimination in natural scene stimuli.
