Adaptation to numerosity affects the pupillary light response

The dataset reports per participant and condition averages of peak pupil constrictions (columns P_...) and reported numerosity (columns B_...) from two experiments run with 12 and 13 participants (rows) in "Adaptation to numerosity affects the pupillary light response" (Scientific Reports, 2024) by Caponi, Castaldi, Burr and Binda.

Pupil constrictions and numerosity reports were elicited by 500 ms long stimuli of constant luminance but variable numerosity, presented following two types of adapters: low numerosity or high numerosity. Column headers identify the measure (P for pupil constriction and B for behavioural responses), the adaptation condition (low and high) and the numerosity of the array (10, 14, 20, 28 and 40). The averages of these values are reported in Figure 2A-B of the publication.

Columns "B_lmh40" and "P_hmlALL" correspond to the data in Figure 2C, quantifying the adaptation effect on reported numerosity and on pupil constrictions respectively.
