Developmental Psychology Research Designs

Assignment 3: Developmental Psychology Research DesignsIn developmental psychology, the focus of research is often to examine change over time. Developmental psychologists have some special research designs that allow them to accomplish this. Two such research designs are the cross-sectional design and the longitudinal design. A cross-sectional design measures different groups of people of different ages at the same time. A longitudinal design measures the same group of people at different ages and also, therefore, at different times.

Use your textbook and the Argosy University online library resources to identify and research a topic in adult development (e.g., memory, muscle strength, etc.) that you wish to examine across various age agroups. Develop an outline for either a cross-sectional or longitudinal research design. Write a paper consisting of the following information:

• An introduction to the topic you selected, including a summary of at least one peer-reviewed journal article describing recent research (post 2005) on the topic;
• A description of how you will measure the topic of study (e.g., the dependent variable).
• A description of which type of design will be used and why that would be most appropriate. Also identify what age groups will be studied.
• On the basis of your readings and research, provide a prediction of what you expect to find upon completion of your study.

Apply APA standards to citation of sources. Your paper should be double-spaced with one-inch margins, written in APA style, and free of typographical and grammatical errors. It should include a title page with a

Introduction

            As people get older, their brain develops and thus, aspects of their memories change. The brain is at its peak when individuals are in their early twenties but the working of the brain starts to decline at the age of forty due to the cortex shrinking. The changes occurring in the brain cause a change in the behavior of the individual whereby, people start forgetting names and the excess effort they are required to put into executive functions. The medial temporal area which caters for long-term memory is also affected…..
