Quizplus · Accepted Answer

According to behavioral genetic research, shared environmental influences (such as family environment) contribute less to individual differences in temperament than nonshared environmental influences (such as unique experiences). This means that nonshared environmental influences contribute more to negatively toned and positively toned temperamental attributes compared to shared environmental influences. However, research suggests that nonshared environmental influences contribute more to positively toned temperamental attributes compared to negatively toned temperamental attributes. Therefore, the best choice is B, which states that shared environmental influences contribute substantially to negatively toned temperamental attributes, and nonshared environmental influences contribute substantially to positively toned temperamental attributes.
