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

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.

The ability to organize and memorize the unfolding of events over time is a fundamental feature cognition, which develops concurrently with maturation brain. Nonetheless, how temporal processing evolves across lifetime as well links underlying neural substrates remains unclear. Here, we intend retrace main developmental stages brain structure, function, cognition linked emergence timing abilities. This neurodevelopmental perspective aims untangle puzzling trajectory aspects lifetime, paving way novel neuropsychological assessments cognitive rehabilitation strategies.

Sensorimotor Activity Patterns using Machine Learning: Assessing the Impact of Auditory Timing Perception and Comparing Different Algorithms

Published: Dec. 2, 2023

Perception and action are the characteristics of human condition define our impact on world around us. The brain's ability to effectively sort incorporate these signals for flawless interactions with environment gives rise hypothesis that processes share an integrated set representations, including arbitrary sense time. Interesting studies investigate how simultaneous activities affect keep track time when we consciously move from one place another. Surprisingly, no study has yet delved into possibility predicting movements based estimates or vice-versa. purpose this is examine role machine learning in statistical prediction sensorimotor tasks explicitly involving isolated auditory tones arm motions, both simultaneously conscious timed actions. dataset was collected via Kaggle consisted 210 trials across 20 right-handed participants each participant completing 14 a block, total 96 trials, sequence conditions pseudo-randomized.

3-2-1, action! A combined motor control-temporal reproduction task shows intentions, motions, and consequences alter time perception

Heliyon, Journal Year: 2023, Volume and Issue: 9(9), P. e19728 - e19728

Published: Sept. 1, 2023

Time estimation is a necessary mechanism for most cognitive functions. Common theories of temporal cognition therefore position the sense time as part central processing, influenced by perception, memory, and affective state, used timing judgements timed responses. In contrast to stages processing models, action-perception theory argues that action-representations alter perception cognition. Here, we propose dynamic, sensorimotor relationship between intention action outcomes determine perception. This hypothesis was tested in three experiments (total N = 94, 57 female, 34 male, 3 non-binary, age 28.6, SD 7.3 years) combined motor control task with reproduction paradigm. Within interval (T1), participants tracked linear moving target using pointing device, then matched T1 manually reproducing it. Despite tracking being independent T1's objective duration, consistently showed subjective biased properties. Experiment 1 distance resistance increased estimates bias while delay visual reduced these bias. 2 replicated findings an online sample, partially extended them towards anticipation. Across studies, experimental manipulation demands use passive conditions show neither attentional mechanisms nor perceptual differences can account observed effects on estimation. Instead, argue representations our shaped intentions behind, motions during, consequences behaviour space.

Near-optimal integration of the magnitude information of time and numerosity

Published: Aug. 1, 2023

Magnitude information is often correlated in the external world, providing complementary about environment. As if to reflect this relationship, perceptions of different magnitudes (e.g. time and numerosity) are known influence one another. Recent studies suggest that such magnitude interaction similar cue integration, as multisensory integration. Here, we tested whether human observers could integrate two quantities with distinct physical units (i.e. abstract information. The participants compared visual stimuli based on time, numerosity, or both. Consistent predictions maximum-likelihood estimation model, integrated numerosity a near-optimal manner; weight each dimension was proportional their relative reliability, estimate more reliable than either estimate. Furthermore, integration approached statistical optimum temporal discrepancy acquisition piece became smaller. These results arises through computational mechanism They also consistent idea processed by generalized system.

Abstract Objective. Detecting movement intention is a typical use of brain–computer interfaces (BCI). However, as an endogenous electroencephalography (EEG) feature, the neural representation insufficient for improving motor-based BCI.
