Depth is defined as the distance from a surface, often using your own body as a reference surface when speaking in terms of depth perception.
In psychology, "depth" can refer to a variety of different concepts, depending on the context in which it is used. Here are a few examples of how "depth" might be used in the field of psychology:
Depth psychology: Depth psychology is a branch of psychology that focuses on the unconscious mind and the ways in which unconscious thoughts, feelings, and motivations can influence behavior. Depth psychology includes theories and approaches such as psychoanalysis, Jungian psychology, and object relations theory.
Depth perception: Depth perception is the ability to perceive the distance between objects and to perceive the relative position of objects in three-dimensional space. Depth perception is important for a variety of tasks, including navigation, object manipulation, and sports.
Depth of processing: Depth of processing refers to the extent to which information is analyzed and encoded in memory. Information that is processed deeply is typically better remembered than information that is processed superficially.
Depth interviews: Depth interviews are a type of qualitative research method in which the researcher conducts in-depth, semi-structured interviews with individual participants. Depth interviews are often used to explore complex or sensitive topics in depth and to gain a rich, detailed understanding of the participants' experiences and perspectives.
