The diagram expresses the visual impression of intangible motion.
In general, there is a process from the left side to the right side. As the stimulus loop is repeated by a continuous tester, the result of the experience meets the perception.
With the stimulus loop, the first box is two dots on the left corner of ups and the right corner of downs, moving to the second box which is empty. The third one is located on the opposite side to the first one. transferring to the forth one which is vacant. These processes are reoperating with intervals of 200ms or 300ms respectively. Both the second and the fourth clear are a space of moving. So, the speed of motion is based on the length of a time. Therefore, the dots will appear to jump vertically or horizontally, and then after some time, they will switch directions spontaneously.
This experiment enables US to see how a direct tactile sensation can perceptually grouped in different ways from those of the regular cycles.
These days, human beings are living in a mechanical world, so they can enjoy a very convenient life. Especially, everybody has more leisure time for physical and mental enjoyment as machines assist them in completing tasks at home or at work, but they are also facing some problems due to their lifestyles being perhaps too comfortable. I would, therefore, like to discuss the advantages and disadvantages of automatic devices.
Noticeably, most of US are given a sense of convenience by automatic systems as they help US save time and money. According to “The Age of Access” by Jeremy Rifkin, who is a famous scholar in the United States, the culture of mechanism is a distinctive feature of our society. We can easily buy things on the Internet without spending our time going to markets or department stores. Also, household chores can easily and rapidly be arranged by online systems.
However, a downside has come into existence. The world is now seeing an increase in obesity because there are too many convenient facilities in human lives. The WHO (World Health Organization) has reported that a great number of people not only lead a sedentary life, but also eat fast, high-calorie food with zero nutrients, which causes various diseases. For example, around 4% of the American population are suffering from obesity, according to the AMA (American Medical Association).
In conclusion, although the culture of mechanism has its advantages, there are some negative effects. Therefore, in my opinion, governments should come up with cost-effective solutions like investing in social health care systems to be able to counter such drawbacks.
