Journal Article
Scheller, M., & Nardini, M. (2024). Correctly establishing evidence for cue combination via gains in sensory precision: Why the choice of comparator matters. Behavior Research Methods, 56(4), 2842-2858. https://doi.org/10.3758/s13428-023-02227-w

Studying how sensory signals from different sources (sensory cues) are integrated within or across multiple senses allows us to better understand the perceptual computations that lie at the foundation of adaptive behaviour. As such, determining the p... Read More about Correctly establishing evidence for cue combination via gains in sensory precision: Why the choice of comparator matters.

Different types of uncertainty in multisensory perceptual decision making (2023)
Journal Article
Aston, S., Nardini, M., & Beierholm, U. (2023). Different types of uncertainty in multisensory perceptual decision making. Philosophical Transactions of the Royal Society B: Biological Sciences, 378(1886), Article 20220349. https://doi.org/10.1098/rstb.2022.0349

Efficient decision-making requires accounting for sources of uncertainty (noise, or variability). Many studies have shown how the nervous system is able to account for perceptual uncertainty (noise, variability) that arises from limitations in its ow...

Background: Sensory substitution and augmentation systems (SSASy) seek to either replace or enhance existing sensory skills by providing a new route to access information about the world. Tests of such systems have largely been limited to untimed, un... Read More about Sensory Augmentation for a Rapid Motor Task in a Multisensory Environment.

Multisensory perception and decision-making with a new sensory skill (2023)
Journal Article

It is clear that people can learn a new sensory skill – a new way of mapping sensory inputs onto world states. It remains unclear how flexibly a new sensory skill can become embedded in multisensory perception and decision-making. To address this, we...

Newly learned shape-colour associations show signatures of reliability-weighted averaging without forced fusion or a memory colour effect (2022)
Journal Article

Reliability-weighted averaging of multiple perceptual estimates (or cues) can improve precision. Research suggests that newly-learned statistical associations can be rapidly integrated in this way for efficient decision-making. Yet, it remains unclea...

Developmental changes in colour constancy in a naturalistic object selection task (2022)
Journal Article
Wedge-Roberts, R., Aston, S., Beierholm, U., Kentridge, R., Hurlbert, A., Nardini, M., & Olkkonen, M. (2023). Developmental changes in colour constancy in a naturalistic object selection task. Developmental Science, 26(2), Article e13306. https://doi.org/10.1111/desc.13306

When the illumination falling on a surface changes, so does the reflected light. Despite this, adult observers are good at perceiving surfaces as relatively unchanging – an ability termed colour constancy. Very few studies have investigated colour co...

Our experience of the world seems to unfold seamlessly in a unitary 3D space. For this to be possible, the brain has to merge many disparate cognitive representations and sensory inputs. How does it do so? I discuss work on two key combination proble... Read More about Merging familiar and new senses to perceive and act in space.
