The function f(x) assigns values between 0 and 1 to word inputs, indicating the association of the words with different concepts. 

In the experiments we ran, the function assigned low values (ranging from 0.0011 to 0.0037) to words like "house," "car," "banana," "love," and "tree." This suggests that these words may have little to no association with the concept(s) that the function is selective for.

However, the word "freedom" was assigned a significantly higher value of 0.0260, indicating a stronger association with the concept(s) that the function is selective for. It is possible that the function is specifically tuned to recognize and associate words related to the concept of "freedom" with higher values.

To further understand the function and determine additional concepts it may be selective for, it is important to run more experiments with a diverse and random selection of words, spanning different categories, including both common and obscure words, and concrete and abstract words.
