Odd-one-out task from Spontaneous perception of numerosity in pre-school children

Each MATLAB file corresponds to one session. The variable “sceglidaqui” contains the main data. Each row a different trial. Crucial parameters are expressed in the following columns: 2-numerosity of the odd stimulus; 3-area change (octaves); 4-density change (octaves); 5-number change (octaves); 9-accuracy (0, wrong, 1, correct); 11-response time (seconds)
