研究显示 母亲的伴侣数量决定了孩子的伴侣数量
A new study suggests that people whose mothers had several serious romantic partners tend to follow the same trajectory. Some people have their mother's eyes. And some, it turns out, grow up to have their mother's romantic history. People whose mothers have been married multiple times or have lived with multiple romantic partners are more likely to do so themselves, according to a new study published in the journal PLoSOne. The longer people are exposed to their mother's cohabitation, the more sexual partners they tend to have. The authors looked at data from surveys of thousands of Americans followed for 24 years. Data on the fathers' marriages wasn't available. The study authors write that, rather than economics or socialization, the most likely explanation was genetic. That is, some people have personality traits that make them better or worse at maintaining relationships. They might be depressed, have trust issues, or not regulate their emotions well. They then pass those traits on to their children, who go on to have similarly short-lived relationships. "It could be that mothers who have more partners don't have great relationship skills, or don't deal with conflict well, or have mental-health problems, each of which can undermine relationships and lead to instability," Claire Kamp Dush, the lead author of the study and an associate professor of human sciences at Ohio State University, said in a statement. "Whatever the exact mechanisms, they may pass these characteristics on to their children, making their children's relationships less stable." |
