In completion techniques, the participant
is given an unfinished sentence, story, argument or conversation
and is asked to complete it (Donoghue 2000).
These techniques are widely used in market research, and
can be divided into two types: (a) completion of sentences
and (b) completion of stories. In the completion of sentences,
respondents are provided with incomplete sentences and
asked to complete them using the first word or phrase that
comes to their mind.
