Theoretical Comparison Two: Ecological Systems Theory and Social Exchange Theory

Understanding the disparities of individuals effected in today’s society has a high priority focus in social work education. However, without understanding how society reacts or adjust to their environment and relationships, a clinician cannot provide the appropriate assistance to clients.

In the Ecological Systems Theory, an assessment of the individual will include a review of the individual specifically and internally, awareness of the groups the individual interacts with, and review of the environment. Individual assessment in social work involves a bio psycho-social-spiritual approach to identity and behavior.  Bronfenbrenner’s The Ecology of Human Development: Experiments by Nature and Design (1979) summarized decades of theory and research about the fundamentals processes that guide life-span development. Unlike most other recent statements of theory Bronfenbrenner’s book did not focus on a specific domain such as social relations or cognition or biological development. Instead, Bronfenbrenner focused on a scientific approach emphasizing the interrelationship of different processes and their contextual variation. Although Bronfenbrenner used this text to develop 50 specific hypotheses concerning developmental processes from infancy through adulthood, these hypotheses have only rarely been tested. Rather, the importance of Bronfenbrenner’s (1979) The Ecology of Human Development and his importance in the field of developmental science are usually summarized in one of two related ways. First, Bronfenbrenner is often credited with bringing attention to contextual variation in human development and helping to move developmental psychology from “the science of the strange behavior of children in strange situations with strange adults for the briefest possible periods of time” (1977, p. 513) to more “ecologically valid” studies of developing individuals in their natural environment. Second, just as Piaget’s rich work is often represented in introductory textbooks by a brief table summarizing his stage theory, Bronfenbrenner’s work is often summarized with a diagram of “ecological theory.”

Social exchange theory is an evolving conceptual framework that can be utilized to explain individual development within the family context. Exchange theory is based on the principle that we enter into relationships in which we can maximize the benefits to us and minimize our costs. Equity theory, a variation of exchange theory, holds that exchanges between people have to be fair and balanced so that they mutually give and receive what is needed. Utilitarian economists made certain assumptions which were applied to exchange theory. They believed:  humans are rational and will seek to maximize their gain. They viewed humans as having access to all the information they needed to make these rational decisions. If a profit cannot be made they will forego that area of investment. Last, a long-term reciprocity is necessary for both participants to make a profit, otherwise one will exploit the other. Behavioral psychology contributed to the following assumptions: an individual will elicit behaviors that will produce the greatest reward and the least punishment. An individual will repeat behaviors that were rewarding in the past, and will keep repeating the behavior as long as it is rewarding. However, the reward will lose its value the more the individual receives the reward.

Cultural anthropology made significant contributions to exchange theory. Sir James Frazer in 1919 made certain assumptions about exchange processes: Exchange processes derive from individuals trying to satisfy basic needs. As these processes consistently produce payoffs, patterns of social interactions are developed. These patterns contribute to the development of social structures and lead to power differentiation in social groups. As clinicians, we must be knowledgeable on how society effects the environment as well as how environment effects society.

Jean Piaget Structural approach Theories and Banduras Social learning theories

According to Jean Piaget structural approaches to cognition, and Social learning theories, both of them had some similarities and different viewpoints in some ways.  Piaget structural approach, cognition children progress through series of four keys stages of cognitive development marked shifts in how they understand the world around them. Piaget believed that children are like little scientist and that they actively try to explore and make sense of the world around them and want to learned.

 Piaget learned this by observed his own children a stage theory of intellectual development that include four stages which are the sensorimotor, stage from birth to the age of 2 years, the preoperational stage from 2 to 7 years, the concrete stage from 7 to 11 years age and the formal operational stages from adolescence, this is a final stage in Piaget theory involved an increase in logic and ability to use deductive reasoning and understanding of abstract ideas. Piaget key concept for his theory are Schema which described both the mental and physical action involved in understanding and knowing. Some of Piaget theories are Assimilation, accommodation and Equilibrium. Piaget belief that children try to strike balance between assimilation and accommodation which is achieved through a mechanism, he called equilibration.

 

Bandura Social Learning Theories, is similar to Piaget Theory in some point but little bit different. Bandura Social leaning theory, has become the most influential theory of learning and development, his concepts of learning theories are important. Bandura theory added social element that people learn a new information and behavior by watching other people. And important an aspect of Bandura social learning theory is the notion of self-efficacy (Bandura 1997). Self-efficacy which refer to a person belief about his or her ability to perform behavior that lead to expected outcome. He said that people learned through observing other, without direct involvement in their experience. (pg.101)  Bandura demonstrated that children learned and imitate behaviors they have observed in other people. One of his example was that Bandura children studies observed and adult acting in a violent ways, when children who watch the act of a violent were brought into the room with children who did not watch that violent act, they children who watch the act imitate violently while the children who did not see the violent act did not act violently. Bandura had identified his three basic model of observational learning: A live model which involved an actual individual and a verbal instructional model which involved description and explanation. The last one was a symbolic model which involved real or fictional characters which displaying behaviors in the books.
