The term 'Segments of Psyches' can be described as the different parts of a person's psyche, or mental state. The crossword solution for this term is IDS, which stands for Id, Ego, and Superego. These three components are part of Sigmund Freud's psychoanalytic theory, which states that the human psyche is composed of three parts: the Id, the Ego, and the Superego. The Id is the unconscious part of the psyche that is driven by instinct and pleasure-seeking behavior. The Ego is the conscious part of the psyche that mediates between the Id and the Superego. The Superego is the moral part of the psyche that is driven by social norms and values.
