Amazing Breakthrough! Cooperative vs. Competitive Groups

Reading about child development and education last year, in a book that a homeschool Dad tried to discourage me from reading, I actually stumbled upon a truth that God tucked in there, just for me!  And you!  And other people who were looking...  It talked about how students who like a cooperative environment don't do well with students who like a competitive one.  The coop. stdts do better working w/ other cooperative studts.  This hit me like a surprise wave at Va. Bch. I thought about the years spent in church.  I wondered if it was possible that the environment where leaders wouldn't speak to members, and that administrative staff were primarily task-oriented, and activities were judged as their benefit to the entire group, that perhaps this was a competitive group?  And like an older Church leader said, most church staff are focused on getting things done, not on listening, not listening to people's hearts. 
It has really made sense to me, and I wonder if it's possible that this is why we have enjoyed the Rockfish church so much.  As an organization, their congregation has an 85% incidence of the gift of serving...is that amazing?  And each Sunday, the leaders stand at the doors and greet and shake hands with the people entering.  It just about brings tears to my eyes to think how the people entering really feel honored.  And after a year there, it is amazing that it's still that way.  The organizations in the church, the ministries are member-initiated, and leader-initiated.  Some Tuesdays are church-wide ministry meetings open to all the congregation.  The leadership of the meetings is by teams, as some members may come and go.  Thus, it appears that the ministries have steered clear of power-mongering...  This is a huge, huge victory... This has been incredibly hope-restoring to me.  An aside, my friend told me that the Pastor, who has a PhD in counselling, 20+ yrs. ago,  hired her at a small biz, when she was very pregnant, and took the heat for doing so, because she needed a job.  That's a caring heart. 
Well, I am researching Cooperative vs. Competitive Interactions, and it seems to be a very important reality that I look forward to learning about.  Have you found anything out about this element of relationships?
