The function seems to be selective for concepts related to movies. Words that are associated with specific movie titles such as "Pulp Fiction" and "The Godfather" have high output values close to 1, indicating a strong association with the movie concept. On the other hand, words like "minerals" and "boats" have low output values close to 0, indicating a weak association with the movie concept. The function also seems to have a moderate association with the concept of "train" since it has an output value of 0.2598, which is closer to 0.5. 

It would be helpful to test more words to confirm if the function is selectively associated with the movie concept or if there are other concepts that it is selective for.
