• Caratterizzazione_y3b_pulito.xls: 
  • Subject ID
  • Age at the beginning of the study
  • Handedness
  • Sex
• Score_BVSCO_pulito.xls:
  • Subject ID
  • columns B-D: graphemes in the three tests of the BVSCO-2
  • columns E-G: z-score computed on normative data for the three tests of the BVSCO-2
  • median z-score: computed on columns E-G
  • at risk: if median z-score is under the -2 threshold (0=not at risk, 1=at risk)
• executions.mat: a matrix for each time point (y1, y2a, y2b, y3a, y3b) and game (copa_q = copy square, copia_seq = copy sequence, tunnel_q = tunnel square, tunnel_ele = tunnel word).
  • first column of all the cell arrays: subject ID
  • second column for the copy games: three sub-matrices with an execution for each level (spontaneous, big, small)
  • columns 2:N for the tunnel games: an average execution for each index of difficulty
  • for each execution, the columns of the sub-matrices are normalized time, normalized x, normalized y and pressure

Copy games

• A matrix for each game and each time point with a number of rows equal to the number of children and a number of columns equal to 2:
  • First column: array with school and child code
  • Second column: executions
• For the two copy games, the data has a dimension of 3 x 1, where 3 are the modalities (spontaneous, big, small) and 1 is the data matrix.
• By accessing the data matrix we have four variables, i.e., normalized time, normalized x, normalized y and pressure.

Tunnel games

• A matrix for each game and each time point with a number of rows equal to the number of children and a number of columns equal to index of difficulty number +1:
  • First column: array with school and child code
  • From the second column onwards: executions, each column corresponds to the "typical" execution (the average) of an ID (5 for square tunnel and 8 for ele tunnel). Sub-matrices contain the data matrix with its four variables. i.e., normalized time, normalized x, normalized y and pressure.
