We compared the semiparametric time-varying autoregressive model (TV-AR) that takes into account the non-stationarity of psychological processes at the individual level, with the standard AR model.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">METHOD<\/h4>\n\n\n\n<p>We conducted analyses of individual time series to assess intra-individual changes in mean levels and inertia on data from two adolescents who completed measures of personality and indicated their situation perceptions and emotions five times a day for 19&nbsp;days.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">RESULTS<\/h4>\n\n\n\n<p>For the less honest, emotional, extraverted, and more agreeable adolescent, the TV-AR model detected reliable changes in the intra-individual dynamics of situation perceptions and emotions whereas, for the other individual, the standard AR model was more preferred, given the lack of changes in the intra-individual dynamics.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">CONCLUSIONS<\/h4>\n\n\n\n<p>Psychological processes dynamics in situation perception and emotions may vary from person to person depending on their personality. This work constitutes a first step in demonstrating that an idiographic approach has advantages in identifying changes in individuals&#8217; perceptions and reactions to situations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>J Pers. 2019 Nov 30. doi: 10.1111\/jopy.12528.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-1353","publication","type-publication","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 -
