Final answer:
Intentional blindness is the failure to notice something due to focused attention on something else. Change blindness refers to the failure to detect changes in the visual environment. Attentional blink is a temporary impairment in attention after perceiving one stimulus.
Step-by-step explanation:
Intentional blindness refers to the failure to notice or attend to certain stimuli, even when they are in plain sight, due to a person actively focusing their attention on something else. An example of intentional blindness is when someone fails to notice a person dressed in a gorilla costume walking among basketball players in a video, because they are too focused on counting the number of times the ball is passed.
Change blindness occurs when a person fails to detect changes in their visual environment. This can happen when the changes are gradual or when the person's attention is focused on something else. For example, in a study, participants failed to notice a red cross passing across a computer screen because they were instructed to focus on either white or black objects.
Attentional blink refers to a brief period of time after perceiving one stimulus during which a person becomes less aware of other stimuli. This temporary impairment in attention can result in individuals failing to detect the second stimulus. An example of attentional blink is when a person fails to notice a second target in a rapid sequence of stimuli, such as letters, because their attention is still occupied by the first target.
