The
model shown is a linear model showing the states of flow
that a person goes through as task difficulty changes. When task difficulty is
low, boredom results, as task difficulty increases then the
states of potential ‘Rush Based Enjoyment’ (RBE)
and ‘Challenge Based Enjoyment’ (CBE) is passed
through and on to anxiety. The change of states is
not instantaneously going directly from boredom to enjoyment
or enjoyment to anxiety, rather the boundaries are fuzzy. At
the peak of enjoyment is the flow state. Once the flow
state has been exited then enjoyment drops off rapidly while
anxiety, felt as risk, exceeds an acceptable level.
