Acute itch induces attentional avoidance of itch-related information (2022)
Journal Article
Etty, S., George, D. N., van Laarhoven, A., & Holle, H. (2022). Acute itch induces attentional avoidance of itch-related information. Acta Dermato-Venereologica, 102, adv00691. https://doi.org/10.2340/actadv.v102.1626

Attention is known to modulate itch intensity. In contrast, the reverse relationship, i.e. the degree to which the presence of an acute itch affects attention, is currently not well understood. The aims of this study were to investigate whether acute... Read More about Acute itch induces attentional avoidance of itch-related information.

Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech (2021)
Journal Article
Sturdy, S., Smith, D. R., & George, D. N. (in press). Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech. Animal Cognition, https://doi.org/10.1007/s10071-021-01567-4

The perceived pitch of human voices is highly correlated with the fundamental frequency (f0) of the laryngeal source, which is determined largely by the length and mass of the vocal folds. The vocal folds are larger in adult males than in adult femal... Read More about Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech.

Speeding up time: Hierarchical Bayesian drift diffusion modelling evidence for accelerating temporal accumulation (2021)
Journal Article
Tipples, J., Lupton, M., & George, D. (2021). Speeding up time: Hierarchical Bayesian drift diffusion modelling evidence for accelerating temporal accumulation. Timing and Time Perception, 9(4), 393-416. https://doi.org/10.1163/22134468-bja10030

Time perception is malleable - it can be made to speed up and slow down by various experimental manipulations including the presentation of a sequence of auditory clicks and also angry facial expressions. Recent evidence supports the idea that audito... Read More about Speeding up time: Hierarchical Bayesian drift diffusion modelling evidence for accelerating temporal accumulation.

The Effects of Time Pressure on Temporal Overestimation Due to Threat (2021)
Journal Article
Tipples, J., Lupton, M., & George, D. (2021). The Effects of Time Pressure on Temporal Overestimation Due to Threat. Timing and Time Perception, 149, 1-14. https://doi.org/10.1163/22134468-bja10027

© 2021 Koninklijke Brill NV, Leiden. How does emotion change the way we perceive time? Studies have shown that we overestimate the duration of faces that express anger of fear-an effect that has been explained as due the speeding of a pacemaker that...

Preexposure along a continuum: Differentiation and association. (2021)
Journal Article
George, D. N., & Haddon, J. E. (2021). Preexposure along a continuum: Differentiation and association. Journal of Experimental Psychology: Animal Learning and Cognition, 47(1), 48-62. https://doi.org/10.1037/xan0000266

In five experiments, we assessed the effects of pre-exposure to simple auditory stimuli on subsequent conditioning and discrimination learning. Experiment 1 showed that pre-exposure to a single stimulus retarded acquisition of conditioned responding... Read More about Preexposure along a continuum: Differentiation and association..

The representation of stimulus conjunction in theories of associative learning : a context-dependent added-elements model (2020)
Journal Article
George, D. N. (in press). The representation of stimulus conjunction in theories of associative learning : a context-dependent added-elements model. Journal of Experimental Psychology: Animal Learning and Cognition, 46(3), 185-204. https://doi.org/10.1037/xan0000252

This paper briefly reviews three theories concerning elemental and configural approaches to stimulus representation in associative learning and presents a new Context-dependent Added Elements Model (C-AEM). This model takes an elemental approach to s... Read More about The representation of stimulus conjunction in theories of associative learning : a context-dependent added-elements model.

Disentangling the effects of attentional weighting and associative mediation in perceptual learning reveals no evidence for associative mediation. (2019)
Journal Article
George, D. N., & Oltean, B. P. (2020). Disentangling the effects of attentional weighting and associative mediation in perceptual learning reveals no evidence for associative mediation. Journal of Experimental Psychology: Learning, Memory, and Cognition, 46(7), 1207–1225. https://doi.org/10.1037/xlm0000773

Learning to categorize perceptually similar stimuli can result in people becoming more sensitive to differences along perceptual dimensions that are relevant to category membership and/or less sensitive to equivalent differences along irrelevant perc...

A computational implementation of a Hebbian learning network and its application to configural forms of acquired equivalence (2019)
Journal Article
Robinson, J., George, D. N., & Heinke, D. (2019). A computational implementation of a Hebbian learning network and its application to configural forms of acquired equivalence. Journal of Experimental Psychology: Animal Learning and Cognition, 45(3), 356-371. https://doi.org/10.1037/xan0000203

We describe and report the results of computer simulations of the three-layer Hebbian network informally described by Honey, Close, and Lin (2010): A general account of discrimination that has been shaped by data from configural acquired equivalence...

Effects of short-term temperature change in the innocuous range on histaminergic and non-histaminergic acute itch (2018)
Journal Article
Lewis, Z., George, D. N., Cowdell, F., & Holle, H. (2019). Effects of short-term temperature change in the innocuous range on histaminergic and non-histaminergic acute itch. Acta Dermato-Venereologica, 99(2), 188-195. https://doi.org/10.2340/00015555-3077

While temperatures in the noxious range are well-known to inhibit acute itch, the impact of temperature in the innocuous temperature range is less well understood. We investigated the effect of alternating short-term temperature changes in the innocu...

More evidence that less is better: Sub-optimal choice in dogs (2018)
Journal Article
Chase, R. J., & George, D. N. (2018). More evidence that less is better: Sub-optimal choice in dogs. Learning and Behavior, 46(4), 462-471. https://doi.org/10.3758/s13420-018-0326-1

The less-is-better effect is a preference for the lesser of two alternatives sometimes observed when they are evaluated separately. For example, a dinner service of 24 intact pieces might be judged to be more valuable than a 40-piece dinner service c... Read More about More evidence that less is better: Sub-optimal choice in dogs.
