Final answer:
Canned laughter is openly used in TV shows and movies to enhance comedy, while claquing was a hidden practice in theater to manipulate audience response.
Step-by-step explanation:
Canned laughter is a form of laughter that is pre-recorded and played during television shows or movies to create the impression of a live audience response.
It is not hidden and is intentionally used to enhance the comedic effect.
On the other hand, 'claquing' refers to the practice of hiring people to applaud or cheer during a performance, typically in theater.
This practice was common in the 19th and early 20th centuries and was often done discreetly, with the claquers being hidden among the regular audience members.
So while canned laughter is openly used and recognized, claquing was done behind the scenes in order to manipulate the audience's response and create a false perception of genuine audience enjoyment or approval.
