MODVIS Workshop
Based on three core assumptions about mental representations of number, this model of visual enumeration specifies analysis methods that can identify when observers rely on different processes to estimate the numerosity of a visual display. Specifically, the model provides a clear criterion for identifying domains of numerosity that correspond to different perceptual or cognitive processes that have been described in numeracy literature, e.g. subitizing. The model predicts how the requirement to give integer responses in enumeration tasks can produce spurious discontinuities in accuracy measures that can be misidentified as evidence for a subitizing process. It is proposed that cumulative link …
