Data in "Database" are organized in subfolders. Each subfolder contains data of the corresponding task. Data from the Paper&Pencil tests are reported in the .xlsx file Numerosity Estimation Task: Each file contains a matrix called “matr”. Each row of the matrix “matr” is a trial. The columns contain the following information: 1^st: Subject response on numerosity 2^nd: Test numerosity 3^rd: Subject response on numerosity 4^th: 0 5^th: Stimulus duration 6^th: Response time Simple Calculation Task: Each file contains a matrix called “MATR”. Each row of the matrix “MATR” is a trial. The columns contain the following information: 1^st: Number of trials 2^nd: Subject response 3^rd: Response time 4^th: First digit 5^th: mathematical symbols (x=1; +=2; –=3) 6^th: Second digit 7^th: Third digit 8^th: Forth digit Complex Calculation Task: Each file contains a matrix called “MATR”. Each row of the matrix “MATR” is a trial. The columns contain the following information: 1^st: Number of trials 2^nd: Subject response 3^rd: Response time 4^th: First digit 5^th: mathematical symbols (x=1; +=2; –=3; /=4) 6^th: Second digit VSWM Task: Data from forward and backward conditions are located in two different subfolders. Each file contains a matrix called “Span”, with the corresponding VSWM span. For more details, please contact the first author.
