I want to use Mixed Models for interpreting reaction times, instead of ANOVA repeated measures with the mean for each subject/condition.

I have several subjects, condition (2 levels) and time delay (6 levels). Each subject obtained 20 reactions times (RTs) for each time delay in the two condition.

Could someone explain to me how to analize the data using Mixed Model, thus using each reaction times for the analysis, and not only the mean per condition as we usually do with classical ANOVA?

I both SPSS or Jamovi, not programming software like R beacuase I have no experience with it.
