Lifespan Development Through the stages The lifespan approach
Erikson’s Theory of development
Marcia (1966) proposed four distinct  ego identity statuses  applied to adolescents, derived from Erikson's theory. Achieving an identity occurs if a person has experienced a crisis and made a commitment. If the young person accepts what is given by parents or some social institution, and does not feel that this conflicts with own identity, this is called "foreclosure." Sometimes teenagers deliberately postpone making any lasting commitment, a "moratorium" phase, with identify put on hold. Finally, there is the "identity diffuse" person who experiences neither an identity crisis nor a commitment to a definite personal identity. This has been called "a commitment to not making a commitment."
Impact  “ Foreclosers" tend to have closer relationships with parents.  "Identity diffuse" students tend to regard parents as indifferent or rejecting and are more likely to respond to peer pressures

Information Processing Theory This theory examines how children focus their attention, encode information, store it in memory and retrieve it, and monitor those activities Children become more sophisticated by building specific knowledge bases

Vygotsky’s Sociocultural Theory Lev Vygotsky stressed that dialogues between children and others fuels development Private speech is talking to oneself to guide behaviour Private speech helps a child understand the world and that of others
Vygotsky’s Sociocultural Theory (cont’d) As the child learns, adults provides less help or make the task slightly harder This engages the child in more complex reasoning
Vygotsky’s Sociocultural Theory (cont’d) The difference between where a child is and where he or she might be with the appropriate assistance is called the zone of proximal development Scaffolding is when an adult sets up a structure to help a child solve a problem
Theory of Mind A recent focus of developmental psychology is the theory of mind Theory of mind is an understanding of mental states such as feelings and intentions, and their causal role in behaviour This understanding develops around age 3
