We group the research under four cross-sectional topics that unite the different contributions: the data used in the research, the theoretical frameworks, the languages and varieties which are represented and the situational contexts which are examined. These projects represent the current state of research in this field and allows the reader to orient themselves within this diverse field but also leaves many questions open and provides impetus for future lines of research. The interaction and collaboration between diverse disciplines is the central aspect which unites all contributions to the special collection.}, language = {en} } @article{BrandtBeckerTetzneretal.2018, author = {Brandt, Naemi D. and Becker, Michael and Tetzner, Julia and Brunner, Martin and Kuhl, Poldi and Maaz, Kai}, title = {Personality across the lifespan exploring measurement invariance of a short Big Five Inventory from ages 11 to 84}, series = {European journal of psychological assessment}, volume = {36}, journal = {European journal of psychological assessment}, number = {1}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {1015-5759}, doi = {10.1027/1015-5759/a000490}, pages = {162 -- 173}, year = {2018}, abstract = {Personality is a relevant predictor for important life outcomes across the entire lifespan. Although previous studies have suggested the comparability of the measurement of the Big Five personality traits across adulthood, the generalizability to childhood is largely unknown. The present study investigated the structure of the Big Five personality traits assessed with the Big Five Inventory-SOEP Version (BFI-S; SOEP = Socio-Economic Panel) across a broad age range spanning 11-84 years. We used two samples of N = 1,090 children (52\% female, M-age = 11.87) and N = 18,789 adults (53\% female, M-age = 51.09), estimating a multigroup CFA analysis across four age groups (late childhood: 11-14 years; early adulthood: 17-30 years; middle adulthood: 31-60 years; late adulthood: 61-84 years). Our results indicated the comparability of the personality trait metric in terms of general factor structure, loading patterns, and the majority of intercepts across all age groups. Therefore, the findings suggest both a reliable assessment of the Big Five personality traits with the BFI-S even in late childhood and a vastly comparable metric across age groups.}, language = {en} } @misc{MiklashevskyFischer2017, author = {Miklashevsky, Alex A. and Fischer, Martin H.}, title = {Commentary: Down with Retirement: Implications of Embodied Cognition for Healthy Aging}, series = {Frontiers in psychology}, volume = {8}, journal = {Frontiers in psychology}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1664-1078}, doi = {10.3389/fpsyg.2017.00599}, pages = {9 -- 22}, year = {2017}, language = {en} } @article{HaemaelaeinenDammhahnAujardetal.2014, author = {Haemaelaeinen, Anni and Dammhahn, Melanie and Aujard, Fabienne and Eberle, Manfred and Hardy, Isabelle and Kappeler, Peter M. and Perret, Martine and Schliehe-Diecks, Susanne and Kraus, Cornelia}, title = {Senescence or selective disappearance?

This bias may cause overestimation of the influence of senescent declines in performance over condition-dependent mortality on demographic processes across taxa. To simultaneously investigate the roles of functional senescence (FS) and intrinsic, extrinsic and condition-dependent mortality in a species with a high predation risk in nature, we compared age trajectories of body mass (BM) in wild and captive grey mouse lemurs (Microcebus murinus) using longitudinal data (853 individuals followed through adulthood). We found evidence of non-random mortality in both settings. In captivity, the oldest animals showed senescence in their ability to regain lost BM, whereas no evidence of FS was found in the wild. Overall, captive animals lived longer, but a reversed sex bias in lifespan was observed between wild and captive populations. We suggest that even moderately condition-dependent EM may lead to negligible FS in the wild. While high EM may act to reduce the average lifespan, this evolutionary process may be counteracted by the increased fitness of the long-lived, high-quality individuals.}, language = {en} } @article{LorenzGleichBecketal.2014, author = {Lorenz, Robert C. and Gleich, Tobias and Beck, Anne and Poehland, Lydia and Raufelder, Diana and Sommer, Werner and Rapp, Michael Armin and Kuehn, Simone and Gallinat, J{\"u}rgen}, title = {Reward anticipation in the adolescent and aging brain}, series = {Human brain mapping : a journal devoted to functional neuroanatomy and neuroimaging}, volume = {35}, journal = {Human brain mapping : a journal devoted to functional neuroanatomy and neuroimaging}, number = {10}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {1065-9471}, doi = {10.1002/hbm.22540}, pages = {5153 -- 5165}, year = {2014}, abstract = {Processing of reward is the basis of adaptive behavior of the human being. Neural correlates of reward processing seem to be influenced by developmental changes from adolescence to late adulthood. The aim of this study is to uncover these neural correlates during a slot machine gambling task across the lifespan. Therefore, we used functional magnetic resonance imaging to investigate 102 volunteers in three different age groups: 34 adolescents, 34 younger adults, and 34 older adults. We focused on the core reward areas ventral striatum (VS) and ventromedial prefrontal cortex (VMPFC), the valence processing associated areas, anterior cingulate cortex (ACC) and insula, as well as information integration associated areas, dorsolateral prefrontal cortex (DLPFC), and inferior parietal lobule (IPL). Results showed that VS and VMPFC were characterized by a hyperactivation in adolescents compared with younger adults. Furthermore, the ACC and insula were characterized by a U-shape pattern (hypoactivation in younger adults compared with adolescents and older adults), whereas the DLPFC and IPL were characterized by a J-shaped form (hyperactivation in older adults compared with younger groups). Furthermore, a functional connectivity analysis revealed an elevated negative functional coupling between the inhibition-related area rIFG and VS in younger adults compared with adolescents. Results indicate that lifespan-related changes during reward anticipation are characterized by different trajectories in different reward network modules and support the hypothesis of an imbalance in maturation of striatal and prefrontal cortex in adolescents. Furthermore, these results suggest compensatory age-specific effects in fronto-parietal regions. Hum Brain Mapp 35:5153-5165, 2014. (c) 2014 Wiley Periodicals, Inc.}, language = {en} }
