While reading the newspaper, Luke came across a brightly-colored advertisement. However, he could not read the details because the print was too small. In this case, screens prevented him from reading the advertisement.

- Physiological

Explanation:

As per the question, the 'physiological screens' prevented Luke from being able to read the details that were mentioned in too small print and in vibrant colors. The advertisements are often framed in vibrant and bright colors to make it more appealing and engaging for the viewers(through relating it naturally) and help the makers to make a product acceptable and popular among people more conveniently. Through this, they are also able to prevent them from reading the necessary sensitive information about the product and accept it without giving a serious thought to it. Therefore, the use of 'physiological'(natural) screen through which people can relate to, prevents Luke from reading the details of the advertisement.
