A Predictive Processing Model of Episodic Memory and Time Perception

Neural Computation, Journal Year: 2022, Volume and Issue: 34(7), P. 1501 - 1544

Abstract Human perception and experience of time are strongly influenced by ongoing stimulation, memory past experiences, required task context. When paying attention to time, seems expand; when distracted, it contract. considering based on memory, the may be different than what is in moment, exemplified sayings like “time flies you're having fun.” Experience also depends content perceptual experience—rapidly changing or complex scenes seem longer duration less dynamic ones. The complexity interactions among attention, stimulation a likely reason that an overarching theory has been difficult achieve. Here, we introduce model processing episodic makes use hierarchical predictive coding, short-term plasticity, spatiotemporal formation recall, apply this problem human perception. In experiment with approximately 13,000 participants, investigated effects cognitive load, stimulus reports natural up about 1 minute long. Using our generate estimates, compared performance. Model-based estimates replicated key qualitative biases, including differences load (attention), scene type (stimulation), whether judgment was made current remembered (memory). Our work provides comprehensive foundation for exploring computational basis within coding framework.

The role of consciously timed movements in shaping and improving auditory timing

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 290(1992)

Our subjective sense of time is intertwined with a plethora perceptual, cognitive and motor functions, likewise, the brain equipped to expertly filter, weight combine these signals for seamless interactions dynamic world. Until relatively recently, literature on perception has excluded influence simultaneous activity, yet it been found that circuits in are at core most timing functions. Several studies have now identified concurrent movements exert robust effects perceptual estimates, but critically not assessed how humans consciously judge duration their own movements. This creates gap our understanding mechanisms driving movement-related sensory timing. We sought address this by administering sensorimotor task which we explicitly compared isolated auditory tones arm movements, or both simultaneously. contextualized findings within Bayesian cue combination framework, separate sources temporal information weighted reliability integrated into unitary estimate more precise than either unisensory estimate. results revealed differences accuracy between auditory, movement combined trials, (crucially) trials were accurately timed. Under participants’ estimates sub-optimal when model’s prediction, average. These elucidate previously unknown qualities conscious propose computational can describe create unified, multimodal experiences time.

A neuroadaptive interface shows intentional control alters the experience of time

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 19, 2025

A reliable experience of time is critical for perception and action in the present, accurately remembering our past, successfully planning a future. Theories commonly assume central mechanism keeps by providing relatively independent, internal clock. Recent work, however, shows imaginary self-movements alter subjective time, suggesting role temporal cognition. To test hypothesis that derives from relationship between perception, we designed neuroadaptive interface operating on movement to visualize through virtual reality. EEG activity was classified online as reflecting accelerating or static imagery, which then used feedback adapting velocity optical flow presented star field enable control. Two cybernetic experiments were conducted determine how neuroadaptivity relation affected verbal estimation task. In particularly, contrasted (e.g. imagined running > visual acceleration) with non-adaptive (imagined standing pseudoadaptive (sham) conditions. Movement imagery biased estimated duration while intentional control increased judgements passage time. We conclude co-determine Furthermore, action-our evaluation perceived intentionally produced-alters Finally, discuss potential novel, methodology an investigative tool disturbances observed psychopathology.

Moving rhythmically can facilitate naturalistic speech perception in a noisy environment

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2044)

Published: April 1, 2025

The motor system is known to process temporal information, and moving rhythmically while listening a melody can improve auditory processing. In three interrelated behavioural experiments, we demonstrate that this effect translates speech Motor priming improves the efficiency of subsequent naturalistic speech-in-noise processing under specific conditions. (i) Moving at lexical rate (~1.8 Hz) significantly compared other rates, such as phrasal or syllabic rates. (ii) impact rhythmic not influenced by whether it self-generated triggered an beat. (iii) Overt vocalization, regardless its semantic content, also enhances These findings provide evidence for functional role in dynamics speech.

Characteristics of time perception in adolescents with non‐suicidal self‐injury and psychiatric disorders comorbidity

Psychiatry and Clinical Neurosciences, Journal Year: 2025, Volume and Issue: unknown

Published: April 11, 2025

Aim Non‐suicidal self‐injury (NSSI) is a prevalent behavior that associated with various mental disorders characterized by without suicidal intent. However, both the neurobiological bases and indicators of risk remain elusive, impeding intervention this disorder. NSSI regulated reward system, which also regulates time perception. This study aimed to investigate perception characteristics in patients evaluate their potential for identifying thoughts behaviors (STBs). Methods A cohort was conducted, involved 93 psychiatric comorbidity (NPC) 84 healthy controls. Participants completed psychological scales temporal reproduction tasks determine adolescents NPC. Follow‐up assessments were conducted 3 months later emergence STBs. Logistic regression nomograms utilized explore predictive value on Results Adolescents NPC demonstrated significant perception, lower ratio (DRR) higher coefficient variation (CV). Notably, CV at baseline probability STBs during follow‐up. The revealed effectively predicts subsequent patients. Conclusion identifies adolescent patients, may serve as novel behavioral indicator early identification suicide. findings contribute better understanding highlight adverse outcomes, offering insights strategies.

Evidence for systematic - yet task- and motor-contingent - rhythmicity of auditory perceptual judgements

Published: May 7, 2025

Numerous studies advocate for a rhythmic mode of perception; however, the evidence in context auditory perception remains inconsistent. We propose that divergent conclusions drawn from previous work stem conceptual and methodological issues. These include ambiguous assumptions regarding origin perceptual rhythmicity, variations listening tasks attentional demands, differing analytical approaches, reliance on fixed participant samples statistical testing. To systematically address these points, we conducted series experiments which human participants performed involving monaural target sounds presented against binaural white noise backgrounds, while also recording eye movements. varied whether stimuli were randomly or required motor initialization by participant, necessity memory across trials manipulation demands modalities. Our findings challenge notion universal rhythmicity hearing, but support existence paradigm- ear-specific fluctuations sensitivity response bias emerge at multiple frequencies. Notably, left right ears appears to be largely independent among participants, strength behavioural data is linked oculomotor activity requirements task. Overall, results resolve conflicting provide specific avenues further into perception.
