Accounting for individual differences in the temporal dynamics of core affectZita OraveczKU Leuven | |
| Abstract: | The term core affect comprises an integral blend of valence and arousal. People’s core affects are not stable but fluctuate across time as a function of external and internal factors. In this talk, a particular stochastic process is proposed as a model for temporal changes and regulatory dynamics in core affect. Based on accumulated knowledge of core affect dynamics, the model assumes that each individual is characterized by an affective home base: a particular combination of valence and arousal that characterizes the person’s baseline core affect around which affective changes fluctuate. To describe these fluctuations, the model further incorporates a homeostatic pull to the individual’s affective home base as well as intra-individual variability components for valence and for arousal. The model will be illustrated by analyzing data from two experience sampling studies measuring core affect at different time-scales. Dynamical model parameters will be related to stable personality dispositions, and the replication of the findings across the two studies will be discussed. Moreover, the issue of model fit will also be investigated. |
