From what I have learned so far in psy132 class I would like to share Urie Bronfenbrenner's ecological systems chart. Bronfenbrenner's chart breaks down the variables that influence children at a young age. it also shows us which are most influential and least influential. the chart is broken down into 5 systems. working from the middle to the outside we have the microsystem, mesosystem, exosystem, macrosystem, and the chronosystem. those variables that are most influential are shown in the microsystem. as we work our way out we find that these variables become less and less influential on children. above i provided an example of Bronfenbrenner's chart.
