ObjectiveDivergent thinking tasks (DTT) are used

to measure creative abilities, how they

change over time or after an intervention.

However, when you measure a person's

creative abilities on two successive days,

their performance can be quite different.

How reliable are divergent thinking tasks

for repeated assessment?
