Rational Number Representation by the Approximate Number System
, 2023 The approximate number system (ANS) enables organisms to represent the approximate number of items in an observed collection, quickly and independently of natural language. Recently, it has been proposed that the ANS goes beyond representing natural numbers by extracting and representing rational numbers (Clarke & Beck 2021a).

Parametric Representation of Tactile Numerosity in Working Memory [PDF]
, 2020 Estimated numerosity perception is processed in an approximate number system (ANS) that resembles the perception of a continuous magnitude. The ANS consists of a right lateralized frontoparietal network comprising the lateral prefrontal cortex (LPFC) and

Numerical tests of the envelope theory for few-boson systems [PDF]
, 2015 The envelope theory, also known as the auxiliary field method, is a simple technique to compute approximate solutions of Hamiltonians for $N$ identical particles in $D$-dimension. The accuracy of this method is tested by computing the ground state of $N$

Two-Level Lattice Neural Network Architectures for Control of Nonlinear Systems [PDF]
, 2020 In this paper, we consider the problem of automatically designing a Rectified Linear Unit (ReLU) Neural Network (NN) architecture (number of layers and number of neurons per layer) with the guarantee that it is sufficiently parametrized to control a ...

The Numeric Ebbinghaus Effect: Evidence for a Density-Area Mechanism of Numeric Estimation?
Journal of Numerical Cognition, 2023 One model of numeric perception is a density-area mechanism: a process that estimates both density and area of an array, then multiplies them to create an estimate of number.

Decoherence of Hydrodynamic Histories: A Simple Spin Model [PDF]
, 1996 In the context of the decoherent histories approach to the quantum mechanics of closed systems, Gell-Mann and Hartle have argued that the variables typically characterizing the quasiclassical domain of a large complex system are the integrals over small ...

Frontiers in Psychology, 2015 Aging often leads to general cognitive decline in domains such as memory and attention. The effect of aging on numerical cognition, particularly on foundational numerical skills known as the Number Sense, is not well known.

Unstable recurrent patterns in Kuramoto-Sivashinsky dynamics [PDF]
, 2008 We undertake a systematic exploration of recurrent patterns in a 1-dimensional Kuramoto-Sivashinsky system. For a small, but already rather turbulent system, the long-time dynamics takes place on a low-dimensional invariant manifold.

NASCO: A New Method and Program to Generate Dot Arrays for Non-Symbolic Number Comparison Tasks
Journal of Numerical Cognition, 2020 Basic numerical abilities are generally assumed to influence more complex cognitive processes involving numbers, such as mathematics. Yet measuring non-symbolic number abilities remains challenging due to the intrinsic correlation between numerical and ...
