Individual differences are the largest contributing factor to error variance in a repeated-measures design. By using a repeated-measures design, the same participants are used for multiple conditions, so individual differences are controlled for and the resulting error variance is reduced. The other factors listed (experimenter effects, subject bias effects, and measurement error) can also contribute to error variance, but individual differences are the largest factor.
