Time Expresion
You can use the present perfect with no specific time expressions ("never", "ever", "many times", "for", "since", "already", "yet" ...). This concept of no specific time is quite difficult to understand, for this reason, then you have particular uses of the present perfect.
Use
The perfect present for actions that occurred in a non-specific time heretofore used. The specific time is not important. Therefore, we do not usually use with the present perfect expressions of specific time ("this morning", "yesterday", "last year" ...).
