Attention modulates trans-saccadic integration.
(2018-01)With every saccade, humans must reconcile the low resolution peripheral information available before a saccade, with the high resolution foveal information acquired after the saccade. While research has shown that we are ... -
Breaking voice identity perception: Expressive voices are more confusable for listeners.
(2019-09)The human voice is a highly flexible instrument for self-expression, yet voice identity perception is largely studied using controlled speech recordings. Using two voice-sorting tasks with naturally varying stimuli, we ... -
Dopamine enhances model-free credit assignment through boosting of retrospective model-based inference.
(eLife, 2021-12-09)Dopamine is implicated in representing model-free (MF) reward prediction errors a as well as influencing model-based (MB) credit assignment and choice. Putative cooperative interactions between MB and MF systems include a ... -
The effects of high variability training on voice identity learning.
(Elsevier, 2019-07)High variability training has been shown to benefit the learning of new face identities. In three experiments, we investigated whether this is also the case for voice identity learning. In Experiment 1a, we contrasted high ... -
Efficiency and prioritization of inference-based credit assignment.
(Elsevier, 2021-07-12)Organisms adapt to their environments by learning to approach states that predict rewards and avoid states associated with punishments. Knowledge about the affective value of states often relies on credit assignment (CA), ... -
Feel the Noise: Relating Individual Differences in Auditory Imagery to the Structure and Function of Sensorimotor Systems.
(2015-11)Humans can generate mental auditory images of voices or songs, sometimes perceiving them almost as vividly as perceptual experiences. The functional networks supporting auditory imagery have been described, but less is ... -
The hippocampus and orbitofrontal cortex jointly represent task structure during memory-guided decision making
(Cell Press, 2021-11-30)The hippocampus, well known for its role in episodic memory, might also be an important brain region for extracting structure from our experiences in order to guide future decisions. Recent evidence in rodents suggests ... -
Human complex exploration strategies are enriched by noradrenaline-modulated heuristics.
(eLife, 2021-01-04)An exploration-exploitation trade-off, the arbitration between sampling a lesser-known against a known rich option, is thought to be solved using computationally demanding exploration algorithms. Given known limitations ... -
Humans represent the precision and utility of information acquired across fixations.
(2022-02-14)Our environment contains an abundance of objects which humans interact with daily, gathering visual information using sequences of eye-movements to choose which object is best-suited for a particular task. This process is ... -
Impaired generalization of speaker identity in the perception of familiar and unfamiliar voices.
(2016-12)In 2 behavioral experiments, we explored how the extraction of identity-related information from familiar and unfamiliar voices is affected by naturally occurring vocal flexibility and variability, introduced by different ... -
An in-depth cognitive examination of individuals with superior face recognition skills.
(2016-09)Previous work has reported the existence of "super-recognisers" (SRs), or individuals with extraordinary face recognition skills. However, the precise underpinnings of this ability have not yet been investigated. In this ... -
Increased discriminability of authenticity from multimodal laughter is driven by auditory information.
(2017-10)We present an investigation of the perception of authenticity in audiovisual laughter, in which we contrast spontaneous and volitional samples and examine the contributions of unimodal affective information to multimodal ... -
Intact word processing in developmental prosopagnosia.
(2017-05-10)A wealth of evidence from behavioural, neuropsychological and neuroimaging research supports the view that face recognition is reliant upon a domain-specific network that does not process words. In contrast, the recent ... -
Learning Temporal Statistics for Sensory Predictions in Aging.
(2016-03)Predicting future events based on previous knowledge about the environment is critical for successful everyday interactions. Here, we ask which brain regions support our ability to predict the future based on implicit ... -
Listeners form average-based representations of individual voice identities.
(2019-06-03)Models of voice perception propose that identities are encoded relative to an abstracted average or prototype. While there is some evidence for norm-based coding when learning to discriminate different voices, little is ... -
Mapping the differential impact of spontaneous and conversational laughter on brain and mind: an fMRI study in autism.
(Oxford University Press, 2024-05-16)Spontaneous and conversational laughter are important socio-emotional communicative signals. Neuroimaging findings suggest that non-autistic people engage in mentalizing to understand the meaning behind conversational ... -
Men and women differ in their perception of gender bias in research institutions.
(2019)There is extensive evidence of gender inequality in research leading to insufficient representation of women in leadership positions. Numbers revealing a gender gap in research are periodically reported by national and ... -
The movement advantage in famous and unfamiliar faces: a comparison of point-light displays and shape-normalised avatar stimuli.
(2013)Facial movement may provide cues to identity, by supporting the extraction of face shape information via structure-from-motion, or via characteristic patterns of movement. Currently, it is unclear whether familiar and ... -
Neural correlates of the affective properties of spontaneous and volitional laughter types.
(2017-01-27)Previous investigations of vocal expressions of emotion have identified acoustic and perceptual distinctions between expressions of different emotion categories, and between spontaneous and volitional (or acted) variants ... -
Older and younger adults' accuracy in discerning health and competence in older and younger faces.
(2014-09)We examined older and younger adults' accuracy judging the health and competence of faces. Accuracy differed significantly from chance and varied with face age but not rater age. Health ratings were more accurate for older ...
