Rapid temporal accumulation in spider fear: Evidence from hierarchical drift diffusion modelling. (2015)
Journal Article
Tipples, J. (2015). Rapid temporal accumulation in spider fear: Evidence from hierarchical drift diffusion modelling. Emotion, 15(6), 742-750. doi:10.1037/emo0000079

Fear can distort our sense of time – making time seem slow or even stand still. Here, I used Hierarchical Drift Diffusion Modelling (HDDM; Vandekerckhove, Tuerlinckx, & Lee, 2008, 2011; Wiecki, Sofer, & Frank, 2013) to test the idea that temporal acc... Read More

Facial emotion modulates the neural mechanisms responsible for short interval time perception (2013)
Journal Article
Tipples, J., Brattan, V., & Johnston, P. (2015). Facial emotion modulates the neural mechanisms responsible for short interval time perception. Brain topography, 28(1), 104-112. doi:10.1007/s10548-013-0350-6

Emotionally arousing events can distort our sense of time. We used mixed block/event-related fMRI design to establish the neural basis for this effect. Nineteen participants were asked to judge whether angry, happy and neutral facial expressions that... Read More

Neural bases for individual differences in the subjective experience of short durations (less than 2 seconds) (2013)
Journal Article
Tipples, J., Brattan, V., & Johnston, P. (2013). Neural bases for individual differences in the subjective experience of short durations (less than 2 seconds). PloS one, 8(1), (e54669). doi:10.1371/journal.pone.0054669. ISSN 1932-6203

The current research was designed to establish whether individual differences in timing performance predict neural activation in the areas that subserve the perception of short durations ranging between 400 and 1600 milliseconds. Seventeen participan... Read More

Electrophysiological responses to violations of expectation from eye gaze and arrow cues (2012)
Journal Article
Tipples, J., Johnston, P., & Mayes, A. (2013). Electrophysiological responses to violations of expectation from eye gaze and arrow cues. Social Cognitive and Affective Neuroscience, 8(5), (509-514). doi:10.1093/scan/nss024. ISSN 1749-5016

Isolating processes within the brain that are specific to human behavior is a key goal for social neuroscience. The current research was an attempt to test whether recent findings of enhanced negative ERPs in response to unexpected human gaze are uni... Read More

When time stands still: Fear-specific modulation of temporal bias due to threat. (2011)
Journal Article
Tipples, J. (2011). When time stands still: Fear-specific modulation of temporal bias due to threat. Emotion, 11(1), (74-80). doi:10.1037/a0022015. ISSN 1528-3542

The current study was designed to test the fear-specific nature of temporal bias due to threat. A temporal bisection procedure was used in which participants (N = 46) were initially trained to recognize short (400 ms) and long (1,600 ms) standard dur... Read More

Negative emotionality influences the effects of emotion on time perception (2008)
Journal Article
Tipples, J. (2008). Negative emotionality influences the effects of emotion on time perception. Emotion, 8(1), (127-131). doi:10.1037/1528-3542.8.1.127. ISSN 1528-3542

In this study I used a temporal bisection task to test if greater overestimation of time due to negative emotion is moderated by individual differences in negative emotionality. The effects of fearful facial expressions on time perception were also e... Read More
