Interpretation |
Attention-hyperactivity profile |
Barkley Disruptive Behavior Rating Scale |
From 0 to 27 points on each scale: inattention and hyperactivity - impulsivity |
Higher scores are considered to have worse results in the performance of each variable (inattention/HI).Values above 15-18 points are considered clinically significant. |
Saccadic movements |
K-D test |
Execution time (in seconds).Number of mistakes made. |
According to age norms.Scores from 42.05 to 106.48 seconds are considered normal adding up to the range of 8 to 10 years.Number of errors: 1 to 3 errors are expected |
Auditory discrimination |
PAF test |
0-28. |
The greater the number of errors, the greater the difficulty in phoneme discrimination.It is estimated that the presence of more than 2 errors implies a deficit. |
Executive functions |
Stroop test |
P, C, PC and interference. |
Tipical T-scores with mean of 50 and deviation of 10.Interference less than zero: difficulties in inhibiting R. |
Working memory |
WISC-IV digit and letter/number retention subtests to obtain the OMI |
The Operative Memory Index (OMI). |
