The title of the first article is “Birth Order Effects on Personality and Achievement WithinFamilies”. The citation is as follows: Paulhus, D. L., Trapnell, P. D., & Chen, D. (1999, November).

Retrieved from org.ezproxy.snhu.edu/stable/40063474#metadata_info_tab_contentsThe purpose of this study was to investigate the impact of birth order among siblings regard to personality development and achievement throughout life. This study relates to personality development directly by analyzing the development of behaviors and traits among siblings, specifically in regards to how it is impacted depending on the order of birth. The researchers predicted that there would be discernable effects on perception-based birth order. They predicted firstborns would be seen as conscientious and achievers, and last-borns would be perceived as agreeable, liberal, and rebellious (Paulhus et al., 1999).

The author claims from their research support and aligns with the theory presented by Frank Sulloway that siblings’ differences in personality do not directly correlate to birth order and preferential treatment from parents, but rather a “…competition among siblings as they fight for a family niche” (Paulhus et al., p. 482). The variables the researchers looked at varied within four different studies that were conducted. They consisted of participants rating themselves and their siblings in regards to scholastic achievement, rebelliousness, birth order, salience comparison, a student takes-home package involving the Big Five-Factor Model, and an adult (over 40 years of age) take-home package evaluating prior evaluations completed with students. These were all measured using a voluntary questionnaire and a comparison type of model.
