Newly learned novel cues to location are combined with familiar cues but not always with each other (2022)
Journal Article
Aston, S., Beierholm, U., & Nardini, M. (2022). Newly learned novel cues to location are combined with familiar cues but not always with each other. Journal of Experimental Psychology: Human Perception and Performance, 48(6), 639-652. https://doi.org/10.1037/xhp0001014

Mature perceptual systems can learn new arbitrary sensory signals (novel cues) to properties of the environment, but little is known about the extent to which novel cues are integrated into normal perception. In normal perception, multiple uncertain... Read More about Newly learned novel cues to location are combined with familiar cues but not always with each other.

Detecting a viewer's familiarity with a face: Evidence from event-related brain potentials and classifier analyses (2021)
Journal Article
Wiese, H., Anderson, D., Beierholm, U., Tuettenberg, S. C., Young, A. W., & Burton, A. M. (2022). Detecting a viewer's familiarity with a face: Evidence from event-related brain potentials and classifier analyses. Psychophysiology, 59(1), Article e13950. https://doi.org/10.1111/psyp.13950

Human observers recognise the faces of people they know efficiently and without apparent effort. Consequently, recognising a familiar face is often assumed to be an automatic process beyond voluntary control. However, there are circumstances in which...

Central tendency biases must be accounted for to consistently capture Bayesian cue combination in continuous response data (2021)
Journal Article
Aston, S., Negen, J., Nardini, M., & Beierholm, U. (2022). Central tendency biases must be accounted for to consistently capture Bayesian cue combination in continuous response data. Behavior Research Methods, 54(1), 508-521. https://doi.org/10.3758/s13428-021-01633-2

Observers in perceptual tasks are often reported to combine multiple sensory cues in a weighted average that improves precision – in some studies, approaching statistically-optimal (Bayesian) weighting, but in others departing from optimality, or not...

Improving Robotic Grasping on Monocular Images Via Multi-Task Learning and Positional Loss (2021)
Conference Proceeding
Prew, W., Breckon, T., Bordewich, M., & Beierholm, U. (2021). Improving Robotic Grasping on Monocular Images Via Multi-Task Learning and Positional Loss. . https://doi.org/10.1109/icpr48806.2021.9413197

In this paper we introduce two methods of improving real-time object grasping performance from monocular colour images in an end-to-end CNN architecture. The first is the addition of an auxiliary task during model training (multi-task learning). Our...

Using the past to estimate sensory uncertainty (2020)
Journal Article
Beierholm, U., Rohe, T., Ferrari, A., Stegle, O., & Noppeney, U. (2020). Using the past to estimate sensory uncertainty. eLife, 9, Article e54172. https://doi.org/10.7554/elife.54172

To form a more reliable percept of the environment, the brain needs to estimate its own sensory uncertainty. Current theories of perceptual inference assume that the brain computes sensory uncertainty instantaneously and independently for each stimul...

Specular highlights improve colour constancy when other cues are weakened (2020)
Journal Article
Wedge-Roberts, R., Aston, S., Beierholm, U., Kentridge, R., Hurlbert, A., Nardini, M., & Olkkonen, M. (2020). Specular highlights improve colour constancy when other cues are weakened. Journal of Vision, 20(12), 1-22. https://doi.org/10.1167/jov.20.12.4

Previous studies suggest that to achieve color constancy, the human visual system makes use of multiple cues, including a priori assumptions about the illumination (“daylight priors”). Specular highlights have been proposed to aid constancy, but the... Read More about Specular highlights improve colour constancy when other cues are weakened.

Using Occam's razor and Bayesian modelling to compare discrete and continuous representations in numerosity judgements (2020)
Journal Article
Spicer, J., Sanborn, A. N., & Beierholm, U. R. (2020). Using Occam's razor and Bayesian modelling to compare discrete and continuous representations in numerosity judgements. Cognitive Psychology, 122, Article 101309. https://doi.org/10.1016/j.cogpsych.2020.101309

Previous research has established that numeric estimates are based not just on perceptual data but also past experience, and so may be influenced by the form of this stored information. It remains unclear, however, how such experience is represented:...

Bayesian transfer in a complex spatial localization task (2020)
Journal Article

Prior knowledge can help observers in various situations. Adults can simultaneously learn two location priors and integrate these with sensory information to locate hidden objects. Importantly, observers weight prior and sensory (likelihood) informat... Read More about Bayesian transfer in a complex spatial localization task.

Older adults sacrifice response speed to preserve multisensory integration performance (2019)
Journal Article

Ageing has been shown to impact multisensory perception, but the underlying computational mechanisms are unclear. For effective interactions with the environment, observers should integrate signals that share a common source, weighted by their reliab...
