I strongly agree that this type of dynamic intelligence can be enhanced through training.

When humans are placed in a stressful situation for the first time, this is usually what happens by default: 1. Human enters stressful situation. 2. Human experiences a physiological stress response, e.g. sweating, stuttering. 3. Human says, "I am freaking out," and loses all confidence in their ability to perform. 4. Loss of confidence leads to decreasing performance, a vicious cycle of failure is entered upon.

With practice / experience, a human can retrain themselves toward: 1. Human enters stressful situation. 2. Human experiences a physiological stress response, e.g. sweating, stuttering. 3. Human says, "I notice that I am experiencing a normal stress response. This is alright, and I will not let it affect my performance." 4. Human performs well, and enters a cycle of increasing confidence.

For me, this is a hard-won observation. For example, there is a tendency to assume that some people are born "good public speakers." I think it is more likely that there are simply people who are better at noticing their own physiological nervousness for what it is, and maintaining their mental composure despite it.

From my own subjective experience, once this ability is gained in one situational domain, it at least partially translates to other domains.
