While there appears to be consensus about the "Status" dimension of interpersonal attitude, I have seen some controversy about the horizontal dimension labeled as "Love" or "Affiliation".

For example, in "Reconsidering power and distance" (1996), Spencer-Oatey proposes that it should be split into one axis for positive/negative affect and another one for distance/closeness. In "How Interpersonal Motives Clarify the Meaning of Interpersonal Behavior: A Revised Circumplex Model" (2006), Horowitz et al. argue that the opposite of "friendly" should be "indifferent", not "hostile".

I also find this reflected in nonverbal behavior research - for instance, prolonged eye contact can signify both a threatening stare and a loving gaze, indicating that the duration of gaze is not dependent on the positive/negative evaluation of the other person, but rather on the amount of interest or the intensity of these feelings.

In a way this reminds me of the "Pleasure-Arousal-Dominance" model, but so far I haven't found a concrete source to connect these models.

Can anybody suggest a psychological work which examines the horizontal dimension(s) in more detail, and offers a validated distinction between the different aspects of "Affiliation" or "Love"?
