This study examined the interplay between university students' trajectories of motivational regulation and autonomous motivation across one semester, exploring both between and within person components. Participants (N = 193) from one large class reported motivation in two-week intervals over the course of one semester. Bivariate latent curve models with structured residuals revealed rates of change in motivational regulation and autonomous motivation were not linear, declining across the first ten weeks of the semester then bouncing back in the final month. Between-person effects of individual change demonstrated mirroring relationships of latent intercepts and slopes across the semester. Within-person findings revealed that autonomous motivation was a negative predictor of future motivation regulation. Students' grade point average only predicted students’ beginning level of motivational regulation. It appears that students with higher states of autonomous motivation view motivation regulation as unnecessary or even a potential threat to their learning pleasure and satisfaction.

这项研究考察了一个学期大学生的动机调节和自主动机轨迹之间的相互影响，探讨了人与人之间的关系。一个大班的参与者（N = 193）在一个学期的过程中每两周报告一次动机。具有结构残差的双变量潜曲线模型显示，动机调节和自主动机的变化率不是线性的，在学期的前十周下降，然后在最后一个月反弹。个体变化的人际效应显示出整个学期中潜在截距和斜率的镜像关系。人内调查结果显示，自主动机是未来动机调节的负面预测因素。学生们' 年平均成绩只能预测学生的动机调节开始水平。似乎具有较高的自主动机状态的学生将动机调节视为对他们的学习乐趣和满意度的不必要甚至潜在的威胁。
