Comparison enhances size sensitivity: neural correlates of outcome magnitude processing. [PDF]

open access: yesPLoS ONE, 2013
Magnitude is a critical feature of outcomes. In the present study, two event-related potential (ERP) experiments were implemented to explore the neural substrates of outcome magnitude processing.

Perceived numerosity: A comparison of magnitude production, magnitude estimation, and discrimination judgments [PDF]

open access: yesPerception & Psychophysics, 1984
In previous studies, modalities with a higher Weber fraction have tended to have a lower power-function exponent. Within a modality, however, the Weber fraction and power-function exponent for individual subjects were unrelated, and the present study largely confirms this finding for the numerosity dimension. More important than discriminability in the

Of huge mice and tiny elephants: Exploring the relationship between inhibitory processes and preschool math skills

open access: yesFrontiers in Psychology, 2016
The cognitive mechanisms underpinning the well-established relationship between inhibitory control and early maths skills remain unclear. We hypothesised that a specific aspect of inhibitory control drives its association with distinct math skills in ...

COMPARISON BETWEEN GROWTH MAGNITUDE OF BLASTOCYSTIS GENOTYPES ISOLATED FROM GASTROINTESTINAL SYMPTOMATIC EGYPTIAN PATIENTS [PDF]

open access: yesJournal of the Egyptian Society of Parasitology, 2023
Blastocystis presents in healthy and diseased persons so its role in disease development is a subjectof debate. This study compared between growth patterns of different symptomatic Blastocystissubtypes.

Sex differences and functional hemispheric asymmetries during number comparison

open access: yesBiology of Sex Differences, 2018
Background Global-local stimuli are hierarchical structures consisting of a larger global structure which is composed of smaller local stimuli. Numbers are also constructed hierarchically, with multi-digit numbers being made up from single digits. During

Cognitive mediators of US-China differences in early symbolic arithmetic.

open access: yesPLoS ONE, 2021
Chinese children routinely outperform American peers in standardized tests of mathematics knowledge. To examine mediators of this effect, 95 Chinese and US 5-year-olds completed a test of overall symbolic arithmetic, an IQ subtest, and three tests each ...

On the indicators for perceiving empty sets as zero

open access: yesActa Psychologica, 2021
The question whether human beings process empty sets as zero has received little research attention. In this study, we used the distance and end effects as indicators for treating empty sets as a numerical entity that represents an absence of quantity ...

Estimation of magnitudes and numerosity in different formats of stimulus presentation: the numerical ratio effect

open access: yesРоссийский психологический журнал, 2022
Introduction. Several researchers discuss the possibility of existence of a common mental system responsible for the estimation of both discrete numerosities and continuous magnitudes. The numerical ratio effect observed during comparison tasks is one of

Order of Magnitude Comparisons of Distance

open access: yesJournal of Artificial Intelligence Research, 1999
Order of magnitude reasoning - reasoning by rough comparisons of the sizes of quantities - is often called `back of the envelope calculation', with the implication that the calculations are quick though approximate. This paper exhibits an interesting class of constraint sets in which order of magnitude reasoning is demonstrably fast ...

Narrowing the Early Mathematics Gap: A Play-Based Intervention to Promote Low-Income Preschoolers’ Number Skills

open access: yesJournal of Numerical Cognition, 2018
Preschoolers from low-income households lag behind preschoolers from middle-income households on numerical skills that underlie later mathematics achievement.
