Test performance in optional shift and configural acquired-equivalence are positively correlated (2024)
Journal Article
Bru Garcia, S., George, D., & Robinson, J. (online). Test performance in optional shift and configural acquired-equivalence are positively correlated. Journal of Experimental Psychology: Animal Learning and Cognition, https://doi.org/10.1037/xan0000384

In 2 experiments, participants completed 2 computer-based tasks: a configural acquired-equivalence procedure and an optional-shift procedure. Both revealed that test performance was positively correlated, even when controlling for non-specific variab...

Absence of Differential Protection From Extinction in Human Causal Learning (2024)
Journal Article
George, D., Haddon, J., & Griffiths, O. (2024). Absence of Differential Protection From Extinction in Human Causal Learning. Journal of Experimental Psychology: Animal Learning and Cognition, https://doi.org/10.1037/xan0000380

Elemental models of associative learning typically employ a common prediction-error term. Following a conditioning trial, they predict that the change in the strength of an association between a cue and an outcome is dependent upon how well the outco...

Attentional bias in psoriasis: The role of processing time and emotional valence (2023)
Journal Article
Etty, S., George, D. N., van Laarhoven, A., Kleyn, C. E., Walton, S., & Holle, H. (online). Attentional bias in psoriasis: The role of processing time and emotional valence. British Journal of Health Psychology, https://doi.org/10.1111/bjhp.12712

Purpose: The present study explored whether people with psoriasis display an attentional bias towards disease-related threat words and whether this bias occurs relatively early during the phase of stimulus disengagement, or during a later maintained...

Competing contextual processes rely on the infralimbic and prelimbic medial prefrontal cortices in the rat (2023)
Journal Article
George, D., Killcross, S., & Haddon, J. (2023). Competing contextual processes rely on the infralimbic and prelimbic medial prefrontal cortices in the rat. Oxford Open Neuroscience, 2, Article kvad003. https://doi.org/10.1093/oons/kvad003

Ambiguous relationships between events may be established using interference procedures such as latent inhibition, extinction, or counterconditioning. Under these conditions, the retrieval of individual associations between a stimulus and outcome is...

Temporal distortion for angry faces: Testing visual attention and action preparation accounts (2023)
Journal Article
Tipples, J., Lupton, M., & George, D. (2023). Temporal distortion for angry faces: Testing visual attention and action preparation accounts. Quarterly Journal of Experimental Psychology, https://doi.org/10.1177/17470218231172856

When asked to judge the duration of a face people typically overestimate the duration of angry compared with neutral faces. A novel feature of the current research was the inclusion of secondary manipulations designed to distort timing performance na...

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

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