Intraindividual variability has been shown in many studies to be well structured over time and capable of predicting a wide range of behaviors. This study provides analyses of weekly variations of health and activity measurements in a sample (N = 52) of ...
Process of vocational change and individual variability during career counselingTo date, the process of career change and intraindividual aspects of variability in the counseling field have received little empirical attention. This research examines the ...
We considered the functional role of control beliefs for cognitive performance by focusing on patterns of stability across multiple trials increasing in level of difficulty. We assessed 56 adults aged 18–88 on working memory tasks. We examined stability ...
In a sample of 165 older individuals assessed twice at a 2-year interval on tasks of fluid and crystallized intelligence, and intensively (120 trials) on a simple reaction time task, we applied an autoregressive model to estimate both (1) amplitude and (2)...
Whereas subjective well-being remains relatively stable across adulthood, emotional experiences show remarkable short-term variability, with younger and older adults differing in both amount and correlates. Repeatedly assessed affect data captures both ...
In this paper, we examine the intra- and interindividual variability of daily affect in adult couples. We use a variety of analytic techniques to inspect the daily fluctuations in emotions and to determine whether such fluctuations are influenced by the ...
The current study examined predictors of individual differences in the magnitude of practice-related improvements achieved by 87 older adults (mean age 63.52 years) over 18 weeks of cognitive practice. Cognitive inconsistency, as measured in both baseline ...
Dynamics in dynamic testingAbstract. Especially for the assessment of intelligence, “Dynamic Testing” (DT) is progressively discussed in the international literature as an alternative to the so-called status test. “Learning tests”, for which the ...
A focus on the study of development and other kinds of changes in the whole individual has been one of the hallmarks of research by Magnusson and his colleagues. A number of different approaches emphasize this individual focus in their respective ways. ...
Abstract. This paper presents Multiple Speed Assessments as an umbrella term to encompass a variety of approaches that include multiple (e.g., 20), short (e.g., 3 min), and often integrated interpersonal simulations to elicit overt ...
Abstract. Intensive longitudinal studies and experience sampling methods are becoming more common in psychology. While they provide a unique opportunity to ask novel questions about within-person processes relating to personality, there is ...
Ambulatory assessment represents a powerful research tool in lifespan psychology because it allows assessing the within-person variability of developmental processes as it occurs within context-specific influences of people’s natural environments. ...
Abstract. The mixed-effects location scale model is an extension of a multilevel model for longitudinal data. It allows covariates to affect both the within-subject variance and the between-subject variance (i.e., the intercept variance) ...
