Socio- ecological models were developed to further the understanding of the dynamic interrelations among various personal and environmental factors. Socioecological models were introduced to urban studies by sociologists associated with the Chicago School after the First World War as a reaction to the narrow scope of most research conducted by developmental psychologists. These models bridge the gap between behavioral theories that focus on small settings and anthropological theories. Introduced as a conceptual model in the 1. Bronfenbrenner until his death in 2. Urie Bronfenbrenner's Ecological Framework for Human Development applies socioecological models to human development. In his initial theory, Bronfenbrenner postulated that in order to understand human development, the entire ecological system in which growth occurs needs to be taken into account. In subsequent revisions, Bronfenbrenner acknowledged the relevance of biological and genetic aspects of the person in human development. At the core of Bronfenbrenner’s ecological model is the child’s biological and psychological makeup, based on individual and genetic developmental history. This makeup continues to be affected and modified by the child’s immediate physical and social environment (microsystem) as well as interactions among the systems within the environment (mesosystems). Other broader social, political and economic conditions (exosystem) influence the structure and availability of microsystems and the manner in which they affect the child. Finally, social, political, and economic conditions are themselves influenced by the general beliefs and attitudes (macrosystems) shared by members of the society. Thus, systems thinking, which is the process of understanding how things influence one another within a whole, is central to ecological models. Generally, a system is a community situated within an environment. Examples of systems are health systems, education systems, food systems, and economic systems. Drawing from natural ecosystems which are defined as the network of interactions among organisms and between organisms and their environment, social ecology is a framework or set of theoretical principles for understanding the dynamic interrelations among various personal and environmental factors. This perspective emphasizes the multiple dimensions (example: physical environment, social and cultural environment, personal attributes), multiple levels (example: individuals, groups, organizations), and complexity of human situations (example: cumulative impact of events over time). From an ecological perspective, the individual is both a postulate (a basic entity whose existence is taken for granted) and a unit of measurement. As a postulate, an individual has several characteristics. First he requires access to an environment, upon which he/she is dependent for knowledge. Second, he is interdependent with other humans; that is, is always part of a population and cannot exist otherwise. Third, he is time bound, or has a finite life cycle. Fourth, he has an innate tendency to preserve and expand life. Fifth, he has capacity for behavioral variability. Ecological systems theory considers a child's development within the context of the systems of relationship that form his or her environment. Bronfenbrenner's ecological framework for human development. Two distinct phases of the theory can be identified. In other words, human beings develop according to their environment; this can include society as a whole and the period in which they live, which will impact behavior and development. This views behavior and development as a symbiotic relationship, which is why this is also known as the “bioecological” model. Ecological systems theory. This system is composed of five socially organized subsystems that support and guide human development. Each system depends on the contextual nature of the person's life and offers an evergrowing diversity of options and sources of growth. Furthermore, within and between each system are bi- directional influences. These bi- directional influences imply that relationships have impact in two directions, both away from the individual and towards the individual. Because we potentially have access to these subsystems we are able to have more social knowledge, an increased set of possibilities for learning problem solving, and access to new dimensions of self- exploration. Microsystem. The microsystem encompasses the relationships and interactions a child has with his or her immediate surroundings such as family, school, neighborhood, or childcare environments. However, interactions at outer levels can still impact the inner structures. This core environment stands as the child's venue for initially learning about the world. As the child's most intimate learning setting, it offers him or her a reference point for the world. The microsystem may provide the nurturing centerpiece for the child or become a haunting set of memories. The caring relations between child and parents (or other caregivers) can help to influence a healthy personality. The structures in this layer impact the child's development by interacting with some structure in his/her microsystem. The child may not be directly involved at this level, but they do feel the positive or negative force involved with the interaction with their own system. The main exosystems that indirectly influence youth through their family include: school and peers, parents' workplace, family social networks and neighborhood community contexts, local politics and industry. Furthermore, absence from a system makes it no less powerful in a life. For example, many children realise the stress of their parent's workplaces without ever physically being in these places. Macrosystems can be used to describe the cultural or social context of various societal groups such as social classes, ethnic groups, or religious affiliates. The effects of larger principles defined by the macrosystem have a cascading influence throughout the interactions of all other layers. The macrosystem influences what, how, when and where we carry out our relations. It may empower her life so that she, in turn, is more affective and caring with her newborn. Family dynamics need to be framed in the historical context as they occur within each system. Processes, per Bronfenbrenner, explain the connection between some aspect of the context or some aspect of the individual and an outcome of interest. The full, revised theory deals with the interaction among processes, person, context and time, and is labeled the Process–Person–Context–Time model (PPCT). Two interdependent propositions define the properties of the model. Furthermore, contrary to the original model, the Process–Person–Context–Time model is more suitable for scientific investigation. To be effective, the interaction must occur on a fairly regular basis over extended periods of time. These forms of interaction in the immediate environment are referred to as proximal processes. Proposition 2: the form, power and content and direction of the proximal processes affecting development vary systematically as a joint function of the characteristics of the developing person, of the environment- immediate and more remote- in which the processes are taking place and the nature of the developmental outcome under consideration. Proximal processes are fundamental to the theory. They constitute the engines of development because it is by engaging in activities and interactions that individuals come to make sense of their world, understand their place in it, and both play their part in changing the prevailing order while fitting into the existing one. Bronfenbrenner acknowledges here the relevance of biological and genetic aspects of the person. Demand characteristics are those that act as an immediate stimulus to another person, such as age, gender, skin color, and physical appearance. These types of characteristics may influence initial interactions because of the expectations formed immediately. Resource characteristics are those that relate partly to mental and emotional resources such as past experiences, skills, and intelligence, and also to social and material resources (access to good food, housing, caring parents, and educational opportunities appropriate to the needs of the particular society). Finally, force characteristics are those that have to do with differences of temperament, motivation, and persistence. According to Bronfenbrenner, two children may have equal resource characteristics, but their developmental trajectories will be quite different if one is motivated to succeed and persists in tasks and the other is not motivated and does not persist. As such, Bronfenbrenner provided a clearer view of individuals' roles in changing their context. The change can be relatively passive (a person changes the environment simply by being in it), to more active (the ways in which the person changes the environment are linked to his or her resource characteristics, whether physical, mental, or emotional), to most active (the extent to which the person changes the environment is linked, in part, to the desire and drive to do so, or force characteristics). Time plays a crucial role in human development. In the same way that both context and individual factors are divided into sub- factors or sub- systems, Bronfenbrenner and Morris wrote about time as constituting micro- time (what is occurring during the course of some specific activity or interaction), meso- time (the extent to which activities and interactions occur with some consistency in the developing person's environment), and macro- time (the chronosystem). Time and timing are equally important because all aspects of the PPCT model can be thought of in terms of relative constancy and change.
