output links. Figure 4.4 shows some results obtained with the model. In all
44
cases, all the output links but one produced negative feedback. Panel (a) shows
a case of routine problem solving; no impasse. Panel (b) shows the insight
case: A previously dormant option suddenly rises above threshold after an
impasse and the previously explored options fall below threshold and cease to
be considered.
