Recently there has been an increasing interest in the impact of video content on the human body. Currently, the using television commercials directly before the climax of a program are becoming a cause for concern. The study was conducted on six children between the age of 4-5 years old and five physiological indicators including brain activity, heart rate, breathing, blinking and electrodermal activity. Analyzed data revealed to us that it is possible the commercials played during the climax of the program may result in a break of concentration and feelings of frustration. And, it is easier to relax and concentrate on the program if commercials were not played during the climax.
