What is the purpose of the propeller?

Selective listening

In real life situations you usually don’t listen to everything that is being said around you. You ignore some information and focus on the rest.

 

Scanning: You listen for the information you need and ignore the rest.

Focusing your attention: It saves you energy and focuses on what is relevant.

• Always read the questions before you start the listening exercise!
