I have a simple question that would help me a lot in interpreting my results

I ran a glmer model in R with the following variables:

  1. a binary DV that is dummy coded

  2. a categorical IV1 named "condition" with three levels. Contrast coded as (-.66, .33, .33) then as (0, .50, -.50)

  3. a categorical IV2 named "prime_type" with two levels contrast coded as -.5,.5

  4. a categorical IV3 named "TP_place" with two levels dummy coded

    Random effects:
     Groups Name        Variance Std.Dev.
     ID     (Intercept) 2.342    1.530   
     item   (Intercept) 1.100    1.049   
    Number of obs: 1527, groups:  ID, 144; item, 30
    

    Fixed effects: Estimate Std. Error z value Pr(>|z|)
    (Intercept) -3.02220 0.33679 -8.973 < 2e-16 *** condition1 0.01811 0.41729 0.043 0.96539
    condition2 0.54350 0.46128 1.178 0.23870
    prime_type1 0.34976 0.48862 0.716 0.47411
    TP_placeright -0.16971 0.23943 -0.709 0.47843
    condition1:prime_type1 -2.00363 0.57737 -3.470 0.00052 *** condition2:prime_type1 -0.80298 0.60180 -1.334 0.18210

I want R to show the names of the levels for all categorical variables in the model output. This is because I'm confused as to whether the estimate for condition1 shows the effect for the first or second contrast coding.
