All stage theories meet the criteria to fit under the organismic umbrella.
Summary At least some aspect of the theories we will be discussing throughout the rest of the semester, with the exception of ecological theory, are considered stage theories. That is, development occurs in a stage-like sequence as opposed to the linear development described in the learning theories. This is basically a repeat of the information contained in the last lecture, although I have given a different example of terms you could use to conduct a search. You should now be ready to conduct a literature search for information on your topic of choice as well as on the theory you have selected. You need to have some keywords in mind.
