The birth order theory states that a personís position in their family does seem to affect their behavior both at home and at school (Morales, 1995 as cited in Dreikurs, 1958). First born children seem to have higher academic achievement than middle or last born children (Paulhus, Trapnelll, & Chen, 1999; Phillips, 1994). These findings have been seen as false by some researchers, who say that factors such as the motherís age at birth, number of siblings, genetics and environment have more to do with academic achievement (Scholastic, 2006). In fact, birth order is a controversial topic, and has been debated for decades.
To make the birth order controversy more complicated, Adler (1927, as cited in Gfroerer, Gfroerer, Curlette, White, & Kern, 2003) has argued that individuals also have a psychological birth order, which also has effects on personality and therefore achievement. Adler has said that ďan individualís given place in the family does not always correspond with how the person psychologically interprets that place.Ē
Birth order has been shown to have a small effect on educational motivation and achievement, even after dealing with confounds such as social status (Marjoribanks, 2003). The bulk of research suggests that being the first born in a family has positive implications. In addition to seeming to have an impact on academic motivation, being first born may also have an impact on creativity (Baer, Oldham, Hollingshead, & Jacobsohn, 2005). Firstbornís also seem to be more heavily represented in academically elite individuals (Hayes, Bronzaft, 1979).
Alfred Adler (1931, as cited in Greenberg, Gueiuno, Lashen, Mayer & Piskowski, 1963) used birth order theory to predict behavior. He theorized that birth order had a significant effect on personality, with both first born and last born children exhibiting higher levels of problem behavior, and middle children ending up resentful of authority. However, he didnít just focus on negative outcomes, as he saw differences in leadership abilities and other positive qualities.
Of course, birth order has different effects depending on the family itself. According to Needlman (2001), there are exceptions to every idea about birth order, but there are also average outcomes. In general, first born children are seen as more responsible, with high parental expectations. The middle born children often feel more adrift in the family and turn to other means of validation, such as friends and activities. Last born children tend to be more easygoing and used to having their way. Yet these are only generalities, as the number of children in a family and the space between births also seems to have an effect on these roles.
The purpose of this study is to compare academic motivation, grade point average, and birth order to determine a correlation between the three. This study should support other research that found a correlation between being first born and high academic motivation.
The participants were 40 students from Missouri Western State University, a mid- size university in northwest Missouri. These participants consist of students in different level Psychology courses. There were significantly more females than males, which seems fairly common on studies done with Psychology students.
The measure used in this study was the Academic Motivation Scale (Baker, 1984), with questions included involving birth order and grade point average.
The participants were given the scale in class, and were anonymous. The professor handed it out to avoid confounds involving experimenter effects, and the students handed the scale back to the professor when they had completed it. The participants received extra credit for participation.
The independent variables of this study are academic motivation and the participantsí birth order- only, first, middle, or last. However, first born and only children will be put into the same group because of their similar experiences. The independent variable had two levels- first born or only child, or later born.
The dependent variable is grade point average (GPA). Birth order, of course, is pre-determined. Academic motivation is a more abstract idea, and so was determined by using a measure to determine a numerical score for a participantís motivation. Grade point average was also determined by number.
A 2(birth order) X 2(GPA) between subjects ANOVA was calculated comparing the motivation of first born participants to the motivation of later born participants. The main effect of being first born on GPA was not significant (F(1,36)=1.265,p>.05). The main effect of being later born on GPA was not significant (F(1,36)=6.144,p<.05). Finally, the interaction was significant (F(1,36)=.897,p>.05).
Birth order effects are so small that many more participants would be needed to find a significant effect in this study.
The limitations of this study are fairly obvious. Many more participants would be needed to show a significant effect. Having a better balance of participantsí gender would also be recommended for future research. This study would need to be reproduced on a much larger scale to be generalized to the public.
