Regional variation in the English verb qualifier system
Nonstandard dialects often use the same form for past tense and past participle of irregular verbs for which the standard language has distinct forms. One possible reason would be that some speakers have a nonstandard system of verb qualifiers (tense, mood, and aspect markers) in which the past tense/past participle distinction is functionally redundant.
