yes the effects of karma will always be there as long as there are causes! In the case of reincarnation, many people have remarkable abilities like in the case of Benjamin Hall Blyth, at the age of six, asked his father at what hour he was born. He was told that he was born at four o'clock. Looking at thte clock to see the present time, he infomed his father of the number of seconds he had lived. His father made the calculation and said to to Benjamin, "you are wrong 172,000 seconds." The boy answered, "oh papa, you have left out two days for the leap years 1820 and 1824,' which was the case.
So, the Law of Psychic Phenomena and Karma and Reincarnation" tells of numerous such prodigies.
