New preprint with
@zfountas@anilkseth & Warrick Roseboom showing biases in duration reports are predicted by salient changes in visual cortex BOLD. Relevant information for time perception arises from sensory processing, no specialised systems needed. 1/7http://biorxiv.org/content/10.1101/2020.01.09.900423v1 …Prikaži ovu nitHvala.

In a preregistered model-based fMRI analysis we show that individual human duration estimates for naturalistic videos can be reproduced from visual cortex BOLD@TimingForumhttps://www.biorxiv.org/content/10.1101/2020.01.09.900423v1 …Prikaži ovu nitHvala.

New preprint: Computational model of attentional dynamics. We generalized the normalization model of attention into the time domain to capture attention to points in time. Data and modeling suggest that voluntary attention is a limited resource over <1 s.https://www.biorxiv.org/content/10.1101/2019.12.21.886051v1 …

Where is time in the brain? New preprint of a pre-registered computational fMRI study relating human duration perception to sensory cortex activity - led by

Conclusion: duration perception can be extracted from mechanisms for perceiving our dynamic sensory environment. No “internal clocks” needed. 7/7

If we can reconstruct the behavioral effect from the video frames, can we reconstruct it from BOLD obtained while people watch the videos? Yes (with BOLD model-behavior correlations)! And only for relevant sensory hierarchies (visual cortex), not for pre-registered controls. 6/7pic.twitter.com/VnGhQTYydF

Then we fed a ConvNet the same videos our participants watched. We constructed duration predictions from the number of salient events detected by the ConvNet. Like our participants, this model over-estimated durations for videos with more salient events (i.e. city videos). 5/7pic.twitter.com/eHSn41vcbZ

Participants watched silent, naturalistic videos depicting busy city scenes (with many salient events, e.g. people walking), or office scenes where little happened. Behaviourally, time was overestimated for videos with more salient events. 4/7pic.twitter.com/BqGeEyPTFq

We therefore reasoned that salient changes in brain activity associated with sensory processing should predict subjective duration reports. We tested this using computational modelling of behaviour & fMRI, all pre-registered with

How do we ‘do’ time? Building on http://tiny.cc/yx9hiz , given that time perception involves the detection of salient changes/events in the environment, the number of salient events in an epoch should give us, in some arbitrary units, a duration estimate. 2/7pic.twitter.com/nxUXPq5HLx

The absolutely worst thing this evening is that all the people who pushed Corbyn to do a u-turn on Brexit will be promoting the likes of Keir Starmer, one of the architects of the disaster, to be the next leader.

Why is it so bad? Uni leaders now run campuses like businesses. They cram students in to get more income; drive down staff costs to divert money to buildings; and impose ever more work to game external metrics/ league tables, to get even more money and growth.
