The ACLs measure aroused attention, sustained attention time and information processing speed. All three are included in the ACLS-6 in a modified clinical format.
Aroused AttentionAroused attention is used to select activities. Not paying attention is usually an indication that the activity is too hard for the person.
Response TimeResponse time starts after you complete the initial directions and ends after they complete the first action. Response time is a practical, clinical measure of information processing speed.
