- OBJECTIVES: The study investigates whether markers of life satisfaction identified in a cross-sectional study-quality of social network, self-rated health, depressive symptoms, locus of control and widowhood, in addition to financial satisfaction and the personality traits of extraversion and neuroticism-predict change in life satisfaction (LSI-Z) across four measurement occasions during a 6-year period in individuals aged 80+. METHOD: Data were drawn from the Swedish OCTO-Twin-study of individuals aged 80 and older. RESULTS: Growth curve analysis showed a relatively consistent significant linear decline in life satisfaction, but certain markers predicted change in life satisfaction. The loss of spouse, in particular in men, and higher levels of depressive symptoms were related to lower levels of life satisfaction over time. CONCLUSION: The results from the study question the notion of a life-long stability of life satisfaction.

Examining variability in the processing of agreement in novice learners : evidence from event-related potentials

- The present study examines both properties of the language and properties of the learner to better understand variability at the earliest stages of second language (L2) acquisition. We used event-related potentials, an oral production task, and a battery of individual differences measures to examine the processing of number and gender agreement in two groups of low-proficiency English-speaking learners of Spanish who were tested in multiple sessions. The results showed an advantage for number, the feature also instantiated in the native language, as both groups showed a native-like P600 response to subject-verb and noun-adjective number violations across sessions. The more advanced group showed larger effects for number and marginal sensitivity to gender violations. These results suggest that native-like processing of shared features is possible even for novice learners, contrary to proposals suggesting that all morphosyntactic dependencies are initially processed in a non-native manner. Working memory (WM) was a predictor of P600 effects for number and also for gender (where the effect was marginal), suggesting that similar abilities may capture variability in the processing of both shared and unique features despite differences in overall sensitivity. Furthermore, whereas WM predicted performance on online tasks (P600 effects/oral production), verbal aptitude predicted performance on tasks examining morphosyntactic accuracy (grammaticality judgment task/oral production). Our results show that the linguistic properties of the L2, the individual characteristics of the learner, and the nature of the task at hand all play an important role in capturing the variability often observed in the L2 processing of agreement.

Longitudinal Mediation of Processing Speed on Age-Related Change in Memory and Fluid Intelligence.
- 2013

In: Psychology and aging. - : American Psychological Association (APA). - 1939-1498 .- 0882-7974. ; 28:4, s. 887-901

Journal article (peer-reviewed)abstract
- Age-related decline in processing speed has long been considered a key driver of cognitive aging. While the majority of empirical evidence for the processing speed hypothesis has been obtained from analyses of between-person age differences, longitudinal studies provide a direct test of within-person change. Using recent developments in longitudinal mediation analysis, we examine the speed-mediation hypothesis at both the within-and between-person levels in two longitudinal studies, Longitudinal Aging Study Amsterdam (LASA) and Origins of Variance in the Oldest-Old (OCTO-Twin). We found significant within-person indirect effects of change in age, such that increasing age was related to lower speed, which in turn relates to lower performance across repeated measures on other cognitive outcomes. Although between-person indirect effects were also significant in LASA, they were not in OCTO-Twin which is not unexpected given the age homogeneous nature of the OCTO-Twin data. A more in-depth examination through measures of effect size suggests that, for the LASA study, the within-person indirect effects were small and between-person indirect effects were consistently larger. These differing magnitudes of direct and indirect effects across levels demonstrate the importance of separating between- and within-person effects in evaluating theoretical models of age-related change.
