Original Answer: The intentional blindness Inattentional blindness(无意识失明应为inattentional blindness) refers to a phenomenon that if people narrowly focus on a particular task, and then they would not be able to pay attention to anything else, as a result, they may fail to notice other unusual things within the fields of their visions. In the lecture, the professor introduces an experiment. In the experiment, volunteers were asked to watch the videos in which people were throwing and passing balls to each other, and then the volunteers were asked to count the times the balls were passed back and forth. However, a person dressed like an animal walked through the middle of the screen, but it turned out that most of the volunteers haven't seen the character. It's really surprising, and it's a good example to illustrate the concept.

Revised Answer (140 words):

Inattentional blindness refers to a phenomenon where people narrowly focus on a specific task, making them unable to pay attention to anything else and potentially failing to notice other unusual occurrences within their field of vision. The professor in the lecture introduced an experiment that effectively illustrates this concept. In this experiment, volunteers were asked to watch a video featuring people passing a ball back and forth while counting the number of passes. During the video, an individual dressed as an animal walked through the scene; however, most volunteers failed to notice this character due to their focus on counting passes. This surprising outcome serves as an excellent example of inattentional blindness in action, demonstrating how concentrating on one task can lead to missing other significant events within our surroundings.

原文：Intentional Inattentional blindness is when people narrowly focused on a single and particular task, they may not be able to pay attention to anything else and might fail to anything notice anything that within their vision field. In the professor's example, there is an experiment that a researcher asks a group of volunteers to watch a video to count how many times this ball has been tossed. In the half of the video, there is a man carried in an animal suit walking into the people and wave arms and jump around them. After they finish watching the video, the researcher asks them whether they see a character wearing an animal suit around them, and the researcher replied that they didn't see it.

(注意力盲点应为inattentional blindness而非intentional blindness。此外，应将“fail to anything”改为“fail to notice anything”。)

修订版（140词）：

Inattentional blindness occurs when people are so focused on a specific task that they may not be able to pay attention to anything else and might fail to notice other things within their field of vision. In the professor's example, an experiment was conducted in which researchers asked a group of volunteers to watch a video and count how many times a ball was tossed among a group of people. Halfway through the video, a person dressed in an animal costume walked into the scene, waving their arms and jumping around. After finishing the video, the researchers asked the volunteers if they had noticed the character in the animal costume. Surprisingly, most of them did not see it because they were too focused on counting the ball tosses. This example clearly illustrates the concept of inattentional blindness, as the participants failed to notice an unusual event due to their concentration on a specific task.
