Psychology: Classic Developmental Research Designs

Research methods have both advantage and disadvantages depending on the nature of the phenomenon and the aim of the study. The research design is used to determine a standardized framework on tests showing incorrect, correct, or inconclusive results. On the occurrence of an untrue hypothesis, the research still gives insights and develops a new direction of the research. Psychologists use different strategies to conduct research; cross-sectional research, longitudinal research and correlational research (Baltes et al 12). Cross-sectional research is based on different individuals with specified characteristics. Examples are using a group of young individuals and carry out corresponding data on another group of old individuals. The advantage of the research is that it can be done at a faster pace and disadvantage is the making of a direct association between effect and cause.

Longitudinal research involves the study of same individuals in a group over a given time frame. The research is open-ended as it can last over several decades. The benefit of the study is observation over the time frame and the major disadvantage is that it is costly. Longitudinal research entails the study of the Gifted and special abilities of individuals. Correlational research is used to decide on measurable association and variables (Baltes et al 14). The research studies the relationship between two variables through the evaluation of available data and arrives with the statistical conclusion. Limitation of the research study is its inability to determine cause-effect of the research. Correlational research is unable to change variables because it can be unethical, impractical or impossible. As a development psychologist, I would prefer using a longitudinal research design used to examine an infant over the development period. The research will facilitate the examination of behavior factors of the same infant and children over a specified period of time.
