Answer:
Signs that refer to males involve touching the forehead because of the act of touching the hat/ imaginary hat.
Explanation:
According to American Sign Language (ASL), Signs that signify or refer to males are generally made to represent someone who's touching his head. This is because the placement of certain signs near with the hand near the forehead alludes to the act of touching/ tipping the hat for men.
Likewise, women used to wear bonnets that were tied under the chin. So, signs that represent women are represented by the placement near the chin.
Thus, signs that refer to males involve touching the forehead because of the act of touching the hat/ imaginary hat.
