The concept of shame is often confused with the concept of guilt. Rather than give you a Reader Digest description of the differences, I'll borrow one that I found online:
"We feel shame when we violate the social norms we believe in. At such moments we feel humiliated, exposed and small and are unable to look another person straight in the eye. We want to sink into the ground and disappear. Shame makes us direct our focus inward and view our entire self in a negative light. Feelings of guilt, in contrast, result from a concrete action for which we accept responsibility. Guilt causes us to focus our attention on the feelings of others."
I suppose that I should next define what I mean by a community based culture and I will attempt to do do by contrasting the thought processes of both. In a 'western' based culture, the world is assumed to operate by discernible and stable rules, contradiction is a problem to be resolved, and entities are viewed as relatively independent agents. Context and relationships between people and objects are relatively downplayed—or, when they are examined, are assumed to operate under parsimonious rules. But with dialectical or holistic (or community based) thinking, a framework more prevalent in East Asian societies, involves greater attention to context and relationships, assumptions of change rather than stasis, and acceptance of contradiction. Analytic thinking is useful for science and daily life. But sometimes dialectical thinking results in more accurate conclusions or pragmatically useful decisions than analytic thinking.
How might this play out? Simply put, western based thinkers see things in straight lines (linear) while community based thinkers see things as circles. Going forward, I'd prefer to use those two terms to describe the world views. These differences map onto more basic differences in attention to context and relationships. In one study, American and Japanese participants were shown cartoon animations of underwater scenes. When reporting what they had seen, Americans tended to start their recollections with mention of the most salient fish in the scene. Japanese were twice as likely as Americans to begin their reporting with the context. Overall the Japanese participants reported 60% more background details and discussed relationships with the background about twice as often as American participants. People from a linear-based culture would be more likely to describe a single fish, while people from a circular-based culture be more likely to describe the pond/lake/ocean.
The values that derive from a circular view aren't necessarily articulated overtly. For example, in Chinese, there are specific terms used greet family members depending on the relationship, and the degree in specificity is much more precise. Brother/sister in English is translated into elder brother/sister or younger brother/sister. Distinctions are made between patriarchal and matriarchal when referring to grandparents, aunts and uncles - and in the case of the latter, terms also identify whether they are older or younger than one's parents. The point is that the specificity of terms reinforces the idea that one is part of something larger than themselves - the family/community - and that one knows their position within that community.
Some of the social norms found within the community world view include a lack of sense of individuality. To borrow from Star Trek, the needs of the many outweigh the needs of the few - or the one. As a result, individual strengths are often suppressed, as achievement sets a societal norm that everyone else is expected to match - and for those who can not, it represents a weakness that reflects poorly on the community and typically results in a sense of shame, as it also reflects on the honor of the community. This leads to a sense of abandonment by the community, which then typically leads to depression. As a matter of fact it's been posited that a major if not the major cause of depression is shame and the loss of community.
I would submit that most people who are shamed as part of their childhood do not recognize it as such. While they may acknowledge the emotional toil, they typically rationalize the results of overachieving as a consequence to be a good thing. I was aware of my sense of shame in my 20's and I recall trying to explain my shame to the equivalent of a camp counselor at the time, but I was unable to articulate the depth of it, and he understood it to mean guilt and his attempt to address my issues wasn't much help at the time. I remain skeptical that people who have not experienced shame at this level can fully appreciate how devastating it can be.
