Chronosystem (not pictured) refers to the time that transpires as the child relates in his various environments. Brofenbrenner’s Ecological Model (1979) explains that the behavior and development of an individual is an interplay of the individual’s biological and personality factors, his environment and the society and culture he was born into. Brofenbrenner also claims that effects of interactions between the individual and his environment are two-directional or characterized by reciprocity. This means that while a child’s development is influenced and molded by his family, school and peers, he likewise influences and molds the behavior of others. The growing child moves through five systems that inter-relate and affect his development. The most basic environment of Sydney is the microsystem, where direct contacts between her and her immediate surroundings result in behaviors such as dependence or independence and cooperation or competition. This includes her relationship with her parents (she is an only child) and extended family members such as her grandparents who care for her during the day when her parents go to work, and her friends and teachers in school. The pure culture of the society her family lives in greatly influences how they live and how Sydney imbibes the culture as she expresses it in her developing personality. In this level, all relationships of Sydney are bidirectional, meaning adults affect her behavior but she, in turn, likewise affects adult behaviors… her physical attributes, personality and capacities (Berk, 2006). Sydney is a very pretty little girl with a matching bubbly personality that adults just seem to gravitate towards her. The mesosystem comprises the linkages and processes that take place between two or more settings with the child in common (Steuer, 1994). A perfect example is how learning in school is supported by follow up lessons in the home. A strong home-school link helps Sydney’s learning and development become consistent and stable so the teacher must make an effort to keep communicating with her parents to give tips on what they are learning in school. Sydney’s father helps her out with her schoolwork by tutoring her with her lessons at home while her mother often goes to her school for special events that call for parent participation. The third level comprising linkages and processes taking place between two or more settings is the exosystem. This includes at least one setting that does not directly involve the child, but still influences the processes within the immediate setting of the child. An example is the parent’s occupation. The workplace of this parent does not contain Sydney, but processes at work may affect her development such as the hours spent there by the parent may affect the parent-child bond. It also affects the development of Sydney’s disposition. According to Campbell (1999), Sydney’s disposition is enabled by social forces to perpetuate relationships of power that limit and constrain her choices, decisions and actions. The fourth system is the macrosystem which includes the customs, values and laws considered important in Sydney’s culture and upbringing. She was born in the US but was brought home to the Philippines, her parents’
