Abstract Temporal information processing (TIP) constitutes a complex construct that underlies many cognitive functions and operates in few hierarchically ordered time domains. This study aimed to verify the relationship between tens of milliseconds hundreds domains, referring perceptual motor timing, respectively. Sixty four young healthy individuals participated this study. They underwent two auditory temporal order judgement tasks assess their performance domain; on basis, groups high-level performers (HLP) low-level (LLP) were identified. Then, maximum tapping task was used evaluate domain. The most remarkable result HLP achieved faster rate synchronised quicker with “internal clock” during than did LLP. shows there is accuracy judging temporally asynchronous stimuli ability achieve maintain pace movement adequate one’s internal pacemaker. could indicate strong contribution common timing mechanism, responsible for organisation coordination behaviours across different millisecond

Abstract The acquisition of information on the timing events or actions (temporal learning) occurs in both subsecond and suprasecond range. However, although relevant differences between participants have been reported temporal learning, role dimensions individual variability affecting performance such tasks is still unclear. Here we investigated this issue, assessing effect field-dependent/independent cognitive style learning Since different mechanisms mediate when a representation self-generated, it depends an external referent, was assessed two conditions. Participants observed stimulus across six repetitions reproduced it. Unbeknownst to them, internally-based (IBL) condition, duration fixed within trial, number defining varied; externally-cued (ECL) defined by same each its varied. reproduction modality also (motor vs. perceptual). Error scores were higher IBL compared ECL; reverse true for variability. Field-independent individuals performed better than field-dependent ones only IBL, as further confirmed correlation analyses. Findings provide evidence that high-level functioning, field dependence/independence, significantly affect range, type fostered specific task demands.

Abstract The ability to sequence movements in response new task demands enables rich and adaptive behavior. Such flexibility, however, is computationally costly can result halting performances. Practicing the same motor repeatedly render its execution precise, fast, effortless, i.e., ‘automatic’. basal ganglia are thought underlie both modes of execution, yet whether how their contributions differ unclear. We parse this rats trained perform cues an overtrained, or ‘automatic’, condition. Neural recordings sensorimotor striatum revealed a kinematic code independent mode. While lesions affected detailed kinematics similarly across modes, they disrupted high-level structure for automatic, but not visually-guided, behaviors. These results suggest that contribute learned movement essential ‘automatic’ skills be dispensable sensory-guided sequences.

Temporal judgments of actions following unilateral brain damage

Abstract Sense of time is a complex construct, and its neural correlates remain to date in most part unknown. To complicate the frame, physical attributes stimulus, such as intensity or movement, influence temporal perception. Although previous studies have shown that perception can be compromised after brain lesion, evidence on role left right hemispheres are meager. In two experiments, study explores ability estimation multi-second actions non-biological movements 33 patients suffering from unilateral lesion. Furthermore, modulatory induced embodiment processes investigated. The results reveal joint contribution depending not only different durations but also presence actions. Indeed, hemisphere damaged find it difficult estimate 4500 ms longer durations, while fail 3000 durations. former when biological action shown, latter movement. Embodiment effect lesions.
