Regarding how culture affects memories, the chinese culture tends to emphasize

contextual detail and information relevant to groups - Different cultures tend to influence how a person perceives the world and how he creates memories. This difference in culture can be very starkly seen between the countries of the west and those of the east. For example, If and American is asked to describe a scene from underwater, he will tend to focus mainly on the prominent fish in the scene. This is because individuals from the western world tend to be focused on those things that are object based. However, a Chinese will tend to focus on those things that are of contextual detail to the fish. For example the color of the water and seaweed, as well as the relationship between the fish with the other elements in the scene.
