The Effect of Birth Order on Students’ Choice of Major Shoko Nakatsuji Hanover College
Birth Order Theory • Sulloway (1996) claims that birth order does have an effect. • Sulloway suggests that children in the same family do not turn out alike because they are competing for parental attention.
Empirical Research on Birth Order • Herrera et al. (2003) find that people believe that birth order affects personality. • First-born: intelligent, responsible, obedient • Later-born: creative, irresponsible, emotional
Empirical Research on Birth Order • Herrera et al. (2003) find that people believe that those with higher birth ranks attain higher occupational prestige. • Herrera et al. (2003) find that those with higher birth ranks do complete more years of school and do have more prestigious occupations.
Empirical Research on Birth Order • Clark and Rice (1982) found that eminent scientists were earlier born than eminent non-scientists.
Hypothesis • First born children will be more likely than later born children to select science and math-related majors.
Birth Order Questionnaire • Number of siblings • Ages of siblings • Types of siblings (biological sibling, adopted-sibling, half-sibling, step-sibling, twin/multiple) • Gender of siblings • Socioeconomic status
Data Collection • Mass survey • Individual class surveys
Participants • Total number of participants: 179 • Male: 65 Female: 114 • Mean age: 19.80 • Year in school: Freshman (36.9%) Sophomore (29.1%) Junior (17.9%) Senior (16.2%)
Birth Order • Only children (6.1%) • First-borns (50.8%) • Second-borns (36.3%) • Third-borns (6.1%) • Fourth-borns (0.6%)
Biology Business Chemistry Computer Science Economics Engineering Geology Mathematics Physics Pre-medicine Science/Math Major Participants Percent science/math majors = 41.3%
Data Analysis • Birth order as a continuous variable • r = .06, p = .45
Data Analysis • Birth order as a categorical variable • 2 = .07, p = .80
Data Analysis • Birth order effect was strongest for sophomores: r = .25, p =.08.
Discussion • Harris (1998): “in recent studies, birth order effects are not found or are found to be negligible.”
