This discussion provides a commentary on Lyons-Ruth's article examining the interface between attachment and intersubjectivity. First, this commentary posits that it may be useful to conceptualize proximity-seeking behaviors more broadly in order to encompass the types of communicative bids observed in the affective face-to-face interactions of parents and infants. Such a revision to this concept underscores the similarity between primitive proximity-seeking behaviors and the drive for intersubjectivity, which may fundamentally constitute part of the same motivational system. Finally, this article argues that both Lyons-Ruth and others have discussed the role of the attachment relationship as promoting the regulation of affects of all valences as opposed to just distress and that the augmentation and regulation of positive affect within the attachment relationship may be a promising direction for future research and theory.
