Any name for this feature of certain dialects where past simple is replaced with past participle?

For the record, I know there is a similar question here that asks about basically the opposite function in some Americam Dialects.

I want to know if there is a name for the type of dialectic feature where a speaker inserts a past participle where a past simple verb would be standard.

Examples:

He done it. I seen him.

Of course, the standard would be:

He did it. I saw him.

This is fairly common in a number of British Dialects. Is there any specific name for this phenomenon, other than just generally saying it is wrong/non-standard/deviant/informal/etc.?
