Final answer:
Hypnosis is a state of extreme self-focus and attention in which minimal attention is given to external stimuli. Inattentional blindness is the failure to notice something that is completely visible because the person is actively attending to something else. Flow states occur when someone is fully engaged and immersed in a task.
Step-by-step explanation:
Hypnosis is a state of extreme self-focus and attention in which minimal attention is given to external stimuli. It is often used in a therapeutic setting to alter thoughts and perceptions. Hypnosis can be a very effective technique for individuals who are open to suggestion.
Another example of a state of extreme self-focus and attention is inattentional blindness, which is the failure to notice something that is completely visible because the person is actively attending to something else. An example of this is the famous gorilla study by Simons and Chabris (1999).
Flow states are another example, characterized by intense concentration and awareness, and occur when someone is fully engaged and immersed in a task.
