Stability and Change in Diffusion Model Parameters over Two Years
In recent years, mathematical models of decision making, such as the diffusion model, have been endorsed in individual differences research. These models can disentangle different components of the decision process, like processing speed, speed–accuracy trade-offs, and duration of non-decisional processes. The diffusion model estimates individual parameters of cognitive process components, thus allowing the study of individual differences. These parameters are often assumed to show trait-like properties, that is, within-person stability across tasks and time. However, the assumption of temporal stability has so far been insufficiently investigated. With this work, we explore stability and c…
Predictors of volitional personality change in younger and older adults: Response surface analyses signify the complementary perspectives of the self and knowledgeable others
Abstract Goals to change personality traits have been linked to self-rated Big Five traits. Extending previous research, we investigated the associations between change goals and diverse personality characteristics (e.g., self-esteem), other-rated Big Five traits, and self-other agreement in an age-heterogeneous sample ( N = 378). Results replicated previous associations of change goals with age and self-rated traits. Additionally, change goals were stronger when others rated a person’s traits as low and when self-other agreement about traits was greater for extraversion, agreeableness, and conscientiousness. Associations of additional personality characteristics with change goals diminish…
You can���t always get what you want: The role of change goal importance, goal feasibility and momentary experiences for volitional personality development
Most adults want to change aspects of their personality. However, previous studies have provided mixed evidence on whether such change goals can be successfully implemented, perhaps partly due to neglecting the goals’ importance and feasibility as well as the experience of trait-relevant situations and states. This study examined associations between change goals and changes in self-reported Big Five traits assessed four times across two years in an age-heterogeneous sample of 382 adults (255 younger adults, Mage = 21.6 years; 127 older adults, Mage = 67.8 years). We assessed trait-relevant momentary situations and states in multiple waves of daily diaries over the first year ( M = 43.9 day…
