The growing body of research on the information processing theory continues to show its application across cognitive, social, and emotional domains. Shaffer and Kipp (2014) suggest that "information-processing approaches probably have more to say about reasons why children succeed and fail in school (and ways to remediate poor academic performance) than any other perspective. And information-processing perspectives are not limited to cognition in the classroom, but also apply to social relations."
Given this perspective, in your initial post, attempt to utilize the information processing theory to explain the mental illness of depression, and discuss what implications this theory has for treatment.
