This paper addresses the significance of the table top shape for the communication.
The investigation into the effects of the table top shape on students in PBL demonstrates that the difference in the shape has influenced the easiness of their concentration. And the experiment concerned with a psychological territory shows it has been generated on the surface of the table top and has been affected by the shape.
These facts point out that the difference in the easiness of the concentration is caused by the discrepancy in a psychological territory which can be traceable to the difference in the table top shape.
