Table 4.

List of Davide's performances before and after different phases of treatment.

	Initial assessment	Control treatment (Testing 2)	Experimental training added to the control treatment (testings 3–4, 5)	Experimental training only (testings 6–7)
Scores that are 2 standard deviations below mean (or below the 5th percentile)	• Sustained attention • Inhibition errors • Inhibition completion time • Switching errors • Switching completion time • Number of words correctly recalled in sequence * • Errors in judging sentence plausibility* • Intrusion errors**	• Inhibition errors • Inhibition completion time • Switching errors • Switching completion time	• Switching completion time • Number of words correctly recalled in sequence • Intrusion errors	• Intrusion errors
Scores that are within normal limits (less than 2 standard deviations below chronological age mean or above the 10th percentile)		• Sustained attention	• Inhibition errors • Inhibition completion time • Switching errors • Errors in judging sentence plausibility	• Number of words correctly recalled in sequence

^*These performances were evaluated in the initial assessment and then in testings 5–7.

^**We infer that these errors would correspond to the deficit range in the initial assessment, as Davide was only able to judge sentence plausibility but did not recall any word in the listening span test.
