^*p<.05,

^†p<.10, determined with chi-square difference tests.

^aSD difference in means for the more restrained class – less restrained class, estimated within the growth model.

^bSD difference in means for individuals waiting 30+ seconds – means for those waiting 0–10 seconds, corresponding to a linear contrast.
