Line Numerosity Judgment Task

The Line Numerosity Judgment Task tests the ability to rapidly estimate the number of visual elements in a display. Participants view displays containing random lines drawn within a circular boundary and must judge whether the display contains a relatively low or high number of lines based on a criterion threshold. The task manipulates both the number of lines (drawn from low and high distributions) and line length (short vs. long) to examine how visual features affect numerosity perception. Performance is measured by accuracy and response times for numerosity judgments. This task assesses approximate number sense, visual enumeration abilities, and how perceptual features influence quantity estimation, making it useful for studying numerical cognition and attention.
