When attention cannot simply be directed
Attention may be carried away by every sound, movement or new thought. At the same time, intense hyperfocus is possible, during which time, hunger and the surroundings are barely registered.
Changing from one activity to another can be harder than the activity itself. A task may be delayed for a long time despite being important, or begun with great energy and later become difficult to finish.
What is often described as ADD tends to appear more quietly. Daydreaming, forgetfulness, mental drifting and intense inner activity may be present without obvious outward restlessness.
