Focused attention: The ability to respond discretely to specific sensory stimuli.

Sustained attention (vigilance and concentration): The ability to maintain a consistent behavioral response during continuous and repetitive activity.

Selective attention: The ability to maintain a behavioral or cognitive set in the face of distracting or competing stimuli. Therefore, it incorporates the notion of "freedom from distractibility."

Alternating attention: The ability of mental flexibility that allows individuals to shift their focus of attention and move between tasks having different cognitive requirements.

Divided attention: This refers to the ability to respond simultaneously to multiple tasks or multiple task demands.

This model has been shown to be very useful in evaluating attention in very different pathologies, correlates strongly with daily difficulties and is especially helpful in designing stimulation programs such as attention process training, a rehabilitation program for neurological patients of the same authors.
Other descriptors for types of attention[edit]

• 
  Mindfulness: Mindfulness has been conceptualized as a clinical model of attention.^[67] Mindfulness practices are clinical interventions that emphasize training attention functions.^[68]
  
• 
  Vigilant attention: Remaining focused on a non-arousing stimulus or uninteresting task for a sustained period is far more difficult than attending to arousing stimuli and interesting tasks, and requires a specific type of attention called 'vigilant attention'.^[69] Thereby, vigilant attention is the ability to give sustained attention to a stimulus or task that might ordinarily be insufficiently engaging to prevent our attention being distracted by other stimuli or tasks.^[70]
