Memory for stimulus sequences distinguishes humans from other animals. Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities.

Researchers have now discovered that humans have a much better memory to recognize and remember sequential information. Ref. Source 1u.
