Abstract Objective Assuming personality to be a system of intra‐individual processes emerging over time in interaction with the environment, we propose an idiographic approach investigate potential changes dynamics perception situations and emotions individuals varying traits. We compared semiparametric time‐varying autoregressive model (TV‐AR) that takes into account non‐stationarity psychological at individual level, standard AR model. Method conducted analyses series assess mean levels inertia on data from two adolescents who completed measures indicated their situation perceptions five times day for 19 days. Results For less honest, emotional, extraverted, more agreeable adolescent, TV‐AR detected reliable whereas, other individual, was preferred, given lack dynamics. Conclusions Psychological may vary person depending personality. This work constitutes first step demonstrating has advantages identifying individuals' reactions situations.
