Demonstration 4:

4 people volunteered to participate in the demonstration.
Mr. Peter read the story to the first person and he told the story to the next person and so on.

As the story was passed on, the story started to change and at the end it was changed quite a bit.
The story was leveled. A quite a detailed story was simplified into a story. Number of the flight stayed for a while but turned into the flight time at the end and the model number of the gun disappeared at the first person and some other details such as radio-ing BKK, people's revolutionary army, angry passengers jumping at the hijacker(?) were lost.

When some details got lost, some got emphasized. The microphone thrown to the hijacker, change of destination to Cuba and name of the gun, although it was changed. these details or information, are weird thus they stood out from the rest and were emphasized. (Sharping)

Some of the changed details were based on the scheme of the person retelling the story. Roland thought there are two pilots in a cockpit and there he invented another pilot in the cockpit. This illustrates assimilation
