A Common Neural Component for Finger Gnosis and Magnitude Comparison
نویسندگان
چکیده
Finger gnosis (the ability to identify which finger has been touched) and magnitude comparison (the ability to determine which of two numbers is larger) are surprisingly correlated. We present a spiking neuron model of a common component that could be used in both tasks: an array of pointers. We show that if the model's single tuned parameter is set to match human accuracy performance in one task, then it also matches on the other task (with the exception of one data point). This provides a novel explanation of the relation, and proposes a common component that could be used across cognitive tasks.

Finger Gnosis And Symbolic Number Comparison as Robust Predictors of Adult Numeracy
Finger gnosis and magnitude comparison were examined as predictors of adult numeracy. Previous findings were extended by (1) controlling for domain-general comparison processes (using a luminance judgment task), (2) controlling for visuo-spatial memory, and (3) examining the robustness of the relations across different numeracy tests, including exact and approximate calculations. Control variab...
متن کاملSubitizing, Finger Gnosis, and the Representation of Number
What precursor abilities form the building blocks of numerical representations? Two abilities were investigated: the ability to mentally represent small numerosities, indexed by subitizing speed (Butterworth, 1999), and the ability to mentally represent one’s fingers, indexed by finger gnosis (Butterworth, 1999; Penner-Wilger & Anderson, 2008). We examined the longitudinal relation between thes...
متن کاملMathematics at Your Fingertips: Testing a Finger Training Intervention to Improve Quantitative Skills
Previous research indicates that the use of fingers as representations of ordinal and cardinal number is an important part of young children’s mathematics learning. Further to this, some studies have shown that a finger training intervention can improve young children’s quantitative skills. In this article, we argue that fingers represent a means for children to connect different external repre...
متن کاملThe relation between finger gnosis and mathematical ability: why redeployment of neural circuits best explains the finding
This paper elaborates a novel hypothesis regarding the observed predictive relation between finger gnosis and mathematical ability. In brief, we suggest that these two cognitive phenomena have overlapping neural substrates, as the result of the re-use ("redeployment") of part of the finger gnosis circuit for the purpose of representing numbers. We offer some background on the relation and curre...
