TL;DR: The fact that Ss receiving small group remedial reading instruction were significantly more accurate in reproducing intervals suggests the possibility that heightened perceptual awareness may result from certain kinds of intensive instruction.
Abstract: 58 fourth and fifth grade children were given Time Questionnaires and a series of short time intervals to be reproduced. Analyses of covariance for three reading levels, controlling for intelligence and age, indicated a significant difference in scores on the Time Questionnaire but negligible differences in the constant error and the standard deviation scores for the reproduced intervals. When two extreme reading groups were compared, the standard deviation scores were significantly smaller for the “better” readers. These scores were also significantly related to the Time Questionnaire scores for the total sample. Sex differences on the questionnaire were confined to the “poorer” readers. The fact that Ss receiving small group remedial reading instruction were significantly more accurate in reproducing intervals suggests the possibility that heightened perceptual awareness may result from certain kinds of intensive instruction.

TL;DR: This work considers how a time perception model that is based on neural networks and the Striatal Beat Frequency theory is extended in a way that besides the duration of events, facilitates the encoding of the time of occurrence in memory.
Abstract: The representation of the environment assumes the encoding of four basic dimensions in the brain, that is the 3D space and time. The vital role of time for cognition is a topic that recently attracted gradually increasing research interest. Surprisingly, the scientific community investigating mind-time interactions has mainly focused on interval timing, paying less attention on the encoding and processing of distant moments. The present work highlights two basic capacities that are necessary for developing temporal cognition in artificial systems. In particular, the seamless integration of agents in the environment assumes they are able to consider when events have occurred and how long they have lasted. This information, although rather standard in humans, is largely missing from artificial cognitive systems. In the present work we consider how a time perception model that is based on neural networks and the Streatal Beat Frequency (SBF) theory is extended in a way that besides the duration of events, facilitates the encoding of the time of occurrence in memory. The extended model is capable to support skills assumed in temporal cognition and answer time-related questions about the unfolded events.

TL;DR: In this paper, the formation and segregation of timescales in electroacoustic music were investigated, where the authors examined how the perception of time is affected by the semantic meaning and the spectromorphological characteristics of sound events.
Abstract: Inspired by Denis Smalley's theoretical ideas on spectromorphology and Albert Bregman's ( 1990 ) auditory scene analysis, I began an investigation into the formation and segregation of timescales 1 in electroacoustic music. This research inevitably led me to an exploration of the factors that shape our perception of time passing and estimation of durations, where spectromorphological issues intermingle with extra-musical associations, autobiographical experiences, emotional responses, and the surrounding environment at the time of listening. Ultimately, time perception affects the structural balance of a composition. This paper, which is part of my ongoing research, examines how the perception of time is affected by the semantic meaning and the spectromorphological characteristics of sound events.

TL;DR: In this article, human participants performed a temporal or color discrimination task of visual stimuli, where they were informed which magnitude they would have to judge before or after presenting the two stimuli (S1 and S2).
Abstract: Studies investigating the neural mechanisms of time perception often measure brain activity while participants perform a temporal task. However, several of these studies are based exclusively on tasks in which time is relevant, making it hard to dissociate activity related to decisions about time from other task-related patterns. In the present study, human participants performed a temporal or color discrimination task of visual stimuli. In different blocks, participants were informed which magnitude they would have to judge before or after presenting the two stimuli (S1 and S2). Our behavioral results showed, as expected, that performance was better when participants knew beforehand which magnitude they would judge. Electrophysiological data (EEG) was analyzed using Linear Discriminant Contrasts (LDC) and a Representational Similarity Analysis (RSA) approach to investigate whether and when information about time and color was encoded. During the presentation of S1, we did not find consistent differences in EEG activity as a function of the task. On the other hand, during S2, we found that temporal and color information was encoded in a task-relevant manner. Taken together, our results suggest that task goals strongly modulate decision-related information in EEG activity.

TL;DR: It is demonstrated that the activation of STN-DBS may either worsen performance or have no effect, but that it is unlikely to lead to significant improvement, which implies that the mechanisms involved in the perceptual processing of temporal information are likely to be functionally independent from those that underpin movement.
