What does sustained attention mean?
Imagine checking a whole document and marking lines with a particular feature. Sustained attention concerns maintaining attention throughout that activity. To observe it, consider performance across the whole series rather than only the first correct response.
Sustained attention and concentration
Concentration concerns focus on a chosen target; sustained attention adds the question of how it continues over time. Switching concerns changing the target or rule. These concepts help describe tasks; they are not independent diagnoses or universal ratings of a person.
How to structure your practice
Choose a clear rule and set the series duration in advance. Track misses, errors and pace, then repeat under similar conditions. Start a separate comparison when the grid or mode changes. One fast Schulte round does not replace observing a longer task.
Keep the rule through the entire list

Step-by-step worked example
What to prepare
Copy the 20 codes in reading order and prepare a pen. Mark only AB7 throughout the series; the criterion stays unchanged.
Task sample
What to do, step by step
Confirm the distinction: AB7 is a target, A87 and AB1 are not. Number positions from 1 to 20.
Read in order and circle each AB7. Familiar opening characters do not make a similar code correct.
Finish the last position, then separate your record into positions 1–10 and 11–20.
Open the check and count missed targets and incorrect circles separately for each half.
How to check your result
AB7 appears at positions 1, 4, 7, 8, 13, 15, 16 and 19: eight targets, four in each half. An error-free pass marks all eight and nothing else. This short worked series is not a general sustained-attention assessment.
Your next attempt
Use a new list with the same length and target count. Compare omissions and extra marks by half; increasing length creates a different condition.
Examples in everyday tasks
Apply one check throughout a report
Review a ten-page report for measurement units: distances should show meters and masses kilograms. Apply the same criterion from the first page to the last. Sustained attention concerns maintaining that check across the task. Record omissions near the beginning and end separately instead of judging only the first correct response.
Keep the target through a long list
Mark only the product code AB7 in a list containing similar codes such as A87 and AB1. As the rows become repetitive, continue using the original rule. Afterwards, compare against a reference and count both missed targets and incorrect marks. The task concerns performance across the whole series.
Verify every calculation
In an expense table, check each row using quantity × price = total. Several correct rows at the start do not establish that the rest are correct. Repeat the same check throughout and note errors or changes in pace. This makes the duration of the activity part of the observation.
