Journal ArticleDOI
The effect of attention and working memory on the estimation of elapsed time
TL;DR: Paying attention to time lengthened perceived duration in the range of seconds to minutes, whereas diverting attention away from time shortened perceived duration, and increasing WM load systematically decreased subjective duration.
Journal ArticleDOI
Sequence Memory in the Hippocampal-Entorhinal Region.
TL;DR: Evidence that temporal relations are a central organizational principle for memories in the hippocampus is summarized, and the idea that the hippocampal–entorhinal region might enable temporal scaling of sequence representations is introduced.
Posted ContentDOI
Hippocampus and striatum encode distinct task regularities that guide human timing behavior
Ignacio Polti,Ignacio Polti,Matthias Nau,Matthias Nau,Matthias Nau,Raphael Kaplan,Raphael Kaplan,Virginie van Wassenhove,Christian F. Doeller,Christian F. Doeller +9 more
TL;DR: In this paper, the authors combine functional magnetic resonance imaging (fMRI) with a visual-tracking and time-to-contact (TTC) estimation task, revealing the widespread brain network supporting sensorimotor learning in real-time.

Rapid encoding of task regularities in the human hippocampus guides sensorimotor timing
Ignacio Polti,Ignacio Polti,Matthias Nau,Matthias Nau,Raphael Kaplan,Raphael Kaplan,Virginie van Wassenhove,Christian F. Doeller,Christian F. Doeller,Christian F. Doeller +9 more
TL;DR: In this paper, the brain encodes the statistical regularities of the environment in a task-specific yet flexible and generalizable format by combining functional magnetic resonance imaging (fMRI) with a fast-paced time-to-contact (TTC) estimation task.
Journal ArticleDOI
Event-related potential correlates of stimulus equivalence classes: A study of task order of the equivalence based priming probes with respect to the stimulus equivalence tests, and among the distinct trial types with each other
Joaquín Menéndez,Federico Sánchez,Ignacio Polti,Sebastián Ariel Idesis,Matías Alejandro Avellaneda,Angel Javier Tabullo,Alberto Andrés Iorio +6 more
TL;DR: Evidence is provided that the EBRP task exhibits priming effects among the SEC stimuli, the behavioral and electrophysiological effects were similar regardless of whether the EbrP task was done before or after the MTS tests, and there were no differences within the baseline and derived trial types in the E BRP task.
