Material culture is the aspect of social reality grounded in the objects and architecture that surround people. It includes the usage, consumption, creation, and trade of objects as well as the behaviors, norms, and rituals that the objects create or take part in. Some scholars also include other intangible phenomena that include sound, smell and events, while some even consider language and media as part of it. The term is most commonly used in archaeological and anthropological studies, to define material or artifacts as they are understood in relation to specific cultural and historic contexts, communities, and belief systems. Material culture can be described as any object that humans use to survive, define social relationships, represent facets of identity, or benefit peoples' state of mind, social, or economic standing. Material culture is contrasting to symbolic culture, which includes nonmaterial symbols, beliefs, and social constructs. The scholarly analysis of material culture, which can include both human made and natural or altered objects, is called material culture studies. It is an interdisciplinary field and methodology that tells of the relationships between people and their things: the making, history, preservation, and interpretation of objects. It draws on both theory and practice from the social sciences and humanities such as art history, archaeology, anthropology, history, historic preservation, folklore, archival science, literary criticism and museum studies, among others. Material value Research in several areas looks into the reasons for perceiving an object as having meaning. Common reasons for valuing material lie in their monetary or sentimental value. A well-known related theory is Kahneman's endowment effect theory. According to Kahneman, people infuse objects they own with a higher value than they do if they do not own the object. The endowment effect is found to occur as soon as an item is acquired and the effect increases over time. Another way in which material can hold meaning and value is by carrying communication between people, just like other communication forms such as speech, touch and gesture. An object can mediate messages between time or space or both between people who are not together. A work of art, for example, can transfer a message from the creator to the viewer and share an image, a feeling, or an experience. Material can contain memories and mutual experiences across time and influence thoughts and feelings. A study found that couples who have more items that were jointly acquired and
