According to my information verbs of perception follow this verb pattern:
Verb of perception + object + gerund
But in an English book, I've found this example which does not really follow this pattern. It uses "compete" rather than "competing", and I am wondering why using an infinitive rather than a gerund in this case?
The example: Do you like seeing people compete on reality shows? If so which ones?
