28. What kind of stress most reliably raises cortisol levels?
ACTH
Cortisol
Tasks with both social-evaluative threat and uncontrollability
Other tasks
Effect size
A meta-analysis of 208 laboratory studies of cortisol responses to acute stressors found that “Tasks that included social-evaluative threat (such as threats to self-esteem or social status), in which others could negatively judge performance, particularly when the outcome of the performance was uncontrollable, provoked larger and more reliable cortisol changes than stressors without these particular threats.” (p.377)
"Humans are driven to preserve the social self and are vigilant to threats that may jeopardize their social esteem or status.” (p.357)

29. Gilligan J. Violence: Our Deadly Epidemic and its Causes.
(G .P. Putnam 1996)
" ...the prison inmates I work with have told me repeatedly, when I asked them why they had assaulted someone, that it was because 'he disrespected me', or 'he disrespected my visit' (meaning 'visitor'). The word 'disrespect' is central in the vocabulary, moral value system, and psychodynamics of these chronically violent men that they have abbreviated it into the slang term, 'he dis'ed me." p.106
A few pages further on Gilligan continues:-
"I have yet to see a serious act of violence that was not provoked by the experience of feeling shamed and humiliated, disrespected and ridiculed, and that did not represent the attempt to prevent or undo this "loss of face " - no matter how severe the punishment, even if it includes death." p.110

30. Social Status and Friendship
Two sides of the same coin:
Social status (dominance hierarchies, pecking orders) are orderings based on power, coercion and privileged access to resources – regardless of the needs of others.
Friendship, in contrast, is based on reciprocity, mutuality, social obligations, sharing and a recognition of each other’s needs.
