Read passage and answer following question.
(1) The three types of human memory allow a person to remove or retain information, as needed. (2) Everything that we notice—see, smell, hear, or touch—forms a brief mental impression called a sensory memory. (3) Information is stored in this sensory memory for only a few tenths of a second before it disappears forever. (4) Information that is retained for slightly longer enters what’s called short-term memory. (5) This form of memory can store about seven items for about thirty seconds—about enough information to dial a telephone number. (6) In order to be remembered for a long period, information must pass into long-term memory. (7) No one knows just how much information can be stored in a person’s long-term memory, but the capacity seems enormous.
