You will see a series of pictures of a scene with a robot standing at a table with some objects on it. You will hear the robot asking a question and a human answering it. Every time you will make a judgment about the robot's question. Between robot scenes you will check the correctness of simple calculations.

In each robot scene there is one object already on the table that the robot knows about, and then another object is being presented by the human. The robot asks a question to verify whether it recognized correctly the type and the color of the new object being shown. Since its recognition capacity is imperfect, it may make a mistake. The human responds to the robot with "yes" or "no".

We would like you to evaluate whether the robot asked the question in a way appropriate to the current scene, irrespective of whether it recognized the object (its type and color) correctly or not. Please forgive the robot's synthetic voice that is sometimes hard to understand.

To enter your evaluation judgment you will select a point on a 5-point scale between good and bad.

We expect that it will take you about 20-25 min to complete the experiment.

Completing this experiment will entitle you for an Amazon Gift Card worth 5 Euros or equivalent (e.g. 6 USD or 4 GBP). For this you need to register at the end of the experiment with a valid e-mail id. Additionally you will be automatically registered for the prize draw of 3 Amazon Gift Card in the value of 20 Euro each or equivalent (e.g. 27 USD or 18 GBP). The winners of the Gift Cards will be drawn among all the registered participants when this experiment is completed (estimated around 31 May, provided we have received minimum 80 participations). Each participant and the prize winners will then be asked to specify their choice of Amazon site for which they would like to get their Gift Card (e.g. amazon.com or amazon.uk, etc.)
