Final answer:
Anxiety related to changes in one's identity is called an identity crisis, which reflects the challenges individuals face in forming their sense of self, influenced by biological, psychological, and sociocultural factors.
Step-by-step explanation:
Anxiety related to changes in one's identity is referred to as identity crisis. This term is often associated with the struggle in finding or forming one's sense of self, which can occur at various life stages. For instance, in Erik Erikson's developmental stages of life, younger individuals may work on overcoming role confusion to achieve identity, while older individuals strive to overcome despair to achieve integrity. Sociologists, as described by Berger, are concerned with both monumental moments and common everyday events in people's lives, which can all play a part in shaping one's identity.
Our identities are the result of complex interactions between our biological and psychological states and are influenced by factors like upbringing, culture, language, and experiences. Cognitive dissonance, referring to discomfort caused by holding conflicting beliefs or thoughts, can disrupt our sense of consistency, which is essential for a coherent identity.
