In order to carry out correct behaviour—that is to say, correct in relation to the survival of the individual—humans have developed innate drives, desires, and emotions and the ability to remember and learn. These fundamental features of living depend on the entire brain, yet… Theories of development The systematic study of children is less than years old, and the vast majority of its research has been published since the mids. Basic philosophical differences over the fundamental nature of children and their growth occupied psychologists during much of the 20th century.
It sounds like studying whether the sky is blue. Popular books invoke birth order for self-discovery, relationship tips, business advice and parenting guidance in titles such as The Birth Order Book: But when scientists scrutinized the data, they found that the evidence just did not hold up.
In fact, until very recently there were no convincing findings that linked birth order to personality or behavior.
Our common perception that birth order matters was written off as an example of our well-established tendency to remember and accept evidence that supports our pet theories while readily forgetting or overlooking that which does not. But two studies from the past three years finally found measurable effects: It may be time to reconsider birth order as a real influence over whom we grow up to be.
Size Matters Before discussing the new findings, it will help to explain why decades of research that seemed to show birth-order effects was, in fact, flawed.
Put simply, birth order is intricately linked to family size. A child from a two-kid family has a 50 percent chance of being a firstborn, whereas a child from a five-kid family has only a 20 percent chance of being a firstborn.
So the fact that astronauts are disproportionately firstborns, for example, could merely show that they come from smaller families—not that firstborns have any particularly astronautic qualities.
Of course, firstborns may indeed have astronautic qualities. The point is that with these data, we cannot tell. There are many reasons that family size could affect our predilections and personalities. More children mean that parental resources money, time and attention have to be spread more thinly.
Perhaps more telling, family size is associated with many important social factors, such as ethnicity, education and wealth.
For example, wealthier, better-educated parents typically have fewer children.
If astronauts are more likely to have well-educated, comfortable parents, then they are also more likely to come from a smaller family and thus are more likely to be a firstborn. Of the some 65, scholarly articles about birth order indexed by Google Scholar, the vast majority suffer from this problem, making the research difficult to interpret.
Many of the few remaining studies fail to show significant effects of birth order. In psychiatrists Cecile Ernst and Jules Angst of the University of Zurich determined, after a thorough review of the literature, that birth-order effects were not supported by the evidence.
By cognitive scientist Steven Pinker of Harvard University found it necessary to spend only two pages of his page discussion of nature and nurture, The Blank Slate Penguindismissing birth order as irrelevant. New Evidence Even so, the case in against birth-order effects was mainly an absence of good evidence, rather than evidence of an absence.
In fact, the past few years have provided good news for the theory. In Norwegian epidemiologists Petter Kristensen and Tor Bjerkedal published work showing a small but reliable negative correlation between IQ and birth order:Jun 11, · Whether you're firstborn, middle child, last-born, or only child, birth order can have a big effect on your personality and ph-vs.com: () Applied behavior analysis (ABA) is a scientific discipline concerned with applying techniques based upon the principles of learning to change behavior of social significance.
