  Cattle have a variety of cognitive abilities. They can memorize the locations of multiple food sources, and can retain memories for at least 48 days. Young cattle learn more quickly than adults, and calves are capable of discrimination learning, distinguishing familiar and unfamiliar animals, and between humans, using faces and other cues. Calves prefer their own mother's vocalizations to those of an unfamiliar cow. Vocalizations provide information on the age, sex, dominance status and reproductive status of the caller, and may indicate estrus in cows and competitive display in bulls. Cows can categorize images as familiar and unfamiliar individuals. Cloned calves from the same donor form subgroups, suggesting that kin discrimination may be a basis of grouping behaviour. Cattle use visual/brain lateralisation when scanning novel and familiar stimuli. They prefer to view novel stimuli with the left eye (using the right brain hemisphere), but the right eye for familiar stimuli. Individual cattle have also been observed to display different personality traits, such as fearfulness and sociability.
