Summary

After using a system, a participant is handed a set of beginnings of sentences that she then completes. The beginnings of the sentences trigger the user think the experiential aspects of product use, e.g."When I use this product, I feel myself…", or "The appearance of this product is…"

Strengths

The participants can freely express themselves so the data is more reliable than traditional questionnaires (which may not provide the right options).
A fun method both for participants and researchers.
The tests are easily administered
Can be used to assess motivations
or attitudes

Weaknesses

Data analysis is quite laborious.
