Abstract: | Three experiments were carried out to study hemispheric specialization for subitizing (the rapid enumeration of small patterns)
and counting (the serial quantification process based on some formal principles). The experiments consist of numerosity identification
of dot patterns presented in one visual field, with a tachistoscopic technique, or eye movements monitored through glasses,
and comparison between centrally presented dot patterns and lateralized tachistoscopically presented digits. Our experiments
show left visual field advantage in the identification and comparison tasks in the subitizing range, whereas right visual
field advantage has been found in the comparison task for the counting range.
