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

Magnitude Estimation and the Non-Linearity of Acceptability Judgments

The term experimental syntax – the use of psycholinguistic methodologies for the collection of acceptability judgments – can cover any number of designs, tasks, and statistical analyses (Cowart 1997, Schütze 1996). Over the past decade, one task in particular, the magnitude estimation task, has received significant attention for its alleged ability to provide more accurate data, almost to the p...

The Discrimination of Magnitude

DASTWAR: a tool for completeness estimation in magnitude-size plane

Today, great observatories around the world, devote a substantial amount of observing time to sky surveys. The resulted images are inputs of source finder modules. These modules search for the target objects and provide us with source catalogues. We sought to quantify the ability of detection tools in recovering faint galaxies regularly encountered in deep surveys. Our approach was based on com...

A common metric magnitude system for the perception and production of numerosity, length, and duration

Numerosity, length, and duration processing may share a common functional mechanism situated within the parietal cortex. A strong parallelism between the processing of these three magnitudes has been revealed by similar behavioral signatures (e.g., Weber-Fechner's law, the distance effect) and reciprocal interference effects. Here, we extend the behavioral evidence for a common magnitude proces...

Comparative judgment of numerosity and numerical magnitude: attention preempts automaticity.

It is commonly believed that humans are unable to ignore the meanings of numerical symbols, even when these meanings are irrelevant to the task at hand. In 5 experiments, the authors tested the notion of automatic activation of numerical magnitude by asking participants to compare, while timed, pairs of numerical arrays on either numerosity or numerical value. Garner and Stroop effects were use...
