Question

If asked to watch a video and press a key each time a black-shirted player passed a basketball, most research participants remained unaware of a gorilla strolling across the video screen. This illustrates?

1) REM sleep deprivation
2) Parallel processing
3) Inattentional blindness
4) Change blindness

Answer 1

Inattentional blindness is the failure to notice something that is completely visible because the person was actively attending to something else. This was demonstrated in a study where participants didn't notice a gorilla walking across a video screen because they were focused on counting basketball passes.

Step-by-step explanation:

Inattentional blindness is the correct answer. Inattentional blindness is the failure to notice something that is completely visible because the person was actively attending to something else and did not pay attention to other things. This phenomenon was demonstrated in a famous study where participants were asked to watch a video and count the number of times a basketball was passed between players wearing black shirts. During the video, a person dressed in a gorilla costume walked across the screen, but nearly half of the participants didn't notice it because they were so focused on counting the basketball passes.
