when considering the causes of secure/insecure attachment, it is probably safest to conclude that...

a. parents, especially mothers, determine attachment behavior in their children as a result of their interactions with the child

b. children's temperament, which is inborn, probably has the most effect on attachment

c. there is no sole influence but it is related more to the way parents and infants develop their relationship to maintain proximity in times of stress

d. issues outside the family, such as the amount of social support a family has, best determines attachment quality
