# What research has been done on attachment types in other primates?

The most canonical experimental paradigm for studying human attachment styles is the Strange Situation leading to classifications such as Secure, Insecure-avoidant, and so on.

What are the equivalent methodologies, classifications, findings and longtitudinal variability in studies of other primates?

I should add that I'm vaguely aware of, say, Harlow's work, but as far as I understand it, it seems to be about the existence of, rather than the variability of, attachment behaviour in animals.
