Effects of perceptual variables on numerosity comparisonin 5-6-year-olds and adults

open access: yesFrontiers in Psychology, 2013
Although a critical issue in the debate over the existence of abstract numerical representation, it remains unclear whether and how perceptual variables affect numerosity judgment and how they change across development stages.

Math Anxiety Mediates the Link Between Number Sense and Math Achievements in High Math Anxiety Young Adults

open access: yesFrontiers in Psychology, 2020
In the past few years, many studies have suggested that subjects with high sensory precision in the processing of non-symbolic numerical quantities (approximate number system; ANS) also have higher math abilities.

Magnitude representations in Williams syndrome: differential acuity in time, space and number processing. [PDF]

open access: yesPLoS ONE, 2013
For some authors, the human sensitivity to numerosities would be grounded in our ability to process non-numerical magnitudes. In the present study, the developmental relationships between non numerical and numerical magnitude processing are examined in ...

Dispersion kinetics in mechanically agitated vessel [PDF]

open access: yesEPJ Web of Conferences, 2019
Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. Prediction of mean drop/particle size and drop/particle size distribution (DSD) is vital for emulsification, suspension ...

Perception of force and stiffness in the presence of low-frequency haptic noise. [PDF]

open access: yesPLoS ONE, 2017
OBJECTIVE:This work lays the foundation for future research on quantitative modeling of human stiffness perception. Our goal was to develop a method by which a human's ability to perceive suprathreshold haptic force stimuli and haptic stiffness stimuli ...

Minimal impairment in a rat model of duration discrimination following excitotoxic lesions of primary auditory and prefrontal cortices

open access: yesFrontiers in Systems Neuroscience, 2011
We present a behavioral paradigm for the study of duration perception in the rat, and report the result of neurotoxic lesions that have the goal of identifying sites that mediate duration perception.

Self-produced Time Intervals Are Perceived as More Variable and/or Shorter Depending on Temporal Context in Subsecond and Suprasecond Ranges

open access: yesFrontiers in Integrative Neuroscience, 2016
The processing of time intervals is fundamental for sensorimotor and cognitive functions. Perceptual and motor timing are often performed concurrently (e.g., playing a musical instrument).
