is a type of frustration response characterized by a person’s tendency to respond to frustration by calmly, weighedly evaluating the events that led to it, without anger or aggression against oneself or others. Failure can be perceived as an inevitable or insignificant event. The term was singled out by S. Rosenzweig (see Rosenzweig, Saul (1907-2004) in Chapter 5 Famous Scientists, Their Scientific Schools and Organizations in Psychological Science).
