Background:

Evaluating numerical cognition requires precise control over visual stimuli, as physical properties often correlate with numerosity.
Existing methods for controlling visual features in nonsymbolic number tasks lack standardization and user flexibility.
Accurate manipulation of visual attributes is crucial to isolate the processing of numerosity itself.

Purpose of the Study:

To introduce the Customized Ultraprecise Standardization-Oriented Multipurpose (CUSTOM) algorithm for generating nonsymbolic number stimuli.
To provide a versatile and highly accurate tool for researchers in numerical cognition.
To enable unbiased investigation of number processing by decoupling numerosity from confounding visual features.

Main Methods:

The CUSTOM algorithm allows free manipulation of stimulus visual features, offering precise control without fixed parameters.
It provides accurate control over visual characteristics, adaptable for various experimental manipulations.
The algorithm facilitates the recreation of stimuli from prior numerical cognition studies.

Main Results:

The CUSTOM algorithm enables the generation of high-precision visual stimuli for nonsymbolic number research.
It offers unparalleled accuracy and flexibility in controlling visual features, addressing a key methodological challenge.
The tool supports a wide range of numerical cognition tasks, including comparison, estimation, and habituation.

Conclusions:

The CUSTOM algorithm is a valuable asset for the field of numerical cognition, offering a standardized approach to stimulus generation.
Its versatility and precision empower researchers to conduct more rigorous and unbiased studies on number processing.
This algorithm facilitates advancements in understanding how the brain processes numerical information.
