English Social Sciences Psychology ambivalent attachment

Hi,
I was wondering about the meaning of “experiential nurturance” in the following passage...It doesn't seem to be a very common expression...
Might it mean: “experience of receiving adequate emotional care/loving care”?
Thanks for any hint!


Another part of this journey for you is to realize that parental presence may seem in short supply in avoidant attachment, that the surface of behaviors is the focus of attention, and that attuning to the internal world of the mind, of the child or even of the self, is simply not often engaged. In this setting, you may have developed with a minimal sense of your own mind, too. The effective strategy to begin with is for you to get in touch with the side of your brain that lets you focus on the internal world—of yourself and of others. That is the right side of the brain.
Since emotions and our bodily sensations fill us with the vitality that makes life rich and meaningful, this avoidant pattern of relating from the left side may have created a disconnected sense of self that is short on the internal joie de vivre, that spirit of being alive, that gives life its zest. This lack of * experiential nurturance * leads, I believe, to an underdevelopment of the right side of the brain.
(..) If you’ve had a hefty dose of avoidance, the left hemisphere may be in charge because it allowed you to develop in the face of an emotional desert. That was a great adaptation for your past. But what about now? What does that mean for your mental life?
