The Center for Lifespan Psychology at the Max Planck Institute for Human Development: Overview of conceptual agenda and illustration of research activities

Founded in 1981 by the late Paul B. Baltes, the Center for Lifespan Psychology at the Max Planck Institute for Human Development has helped to establish lifespan psychology as a distinct conceptual approach within developmental psychology. Recently, the Center has extended its research programme into developmental behavioural neuroscience. Here, we provide an overview of the Center's conceptual agenda, and present two of its seven research projects in greater detail. Work at the Center is guided by three propositions: (1) to study lifespan changes in behaviour as interactions among maturation, learning, and senescence; (2) to develop theories and methods that integrate empirical evidence across domains of functioning, timescales, as well as behavioural and neuronal levels of analysis; (3) to identify mechanisms of development by exploring age-graded differences in plasticity. The Intra-Person Dynamics Project studies the organization of cognitive abilities within individuals of different ages, and investigates lifespan age differences in the plasticity and components of episodic memory performance. The Sensorimotor–Cognitive Couplings Project examines lifespan differences in dynamic dependencies between sensorimotor and cognitive performance. Both projects combine behavioural assessments with methods from developmental neuroscience to delineate age-graded changes in brain–behaviour mappings. Current research in other projects includes: (1) behavioural development in very old age, as assessed in the Berlin Aging Study; (2) the interplay of motivation, affect, and cognition in developmental regulation; (3) behavioural and electrophysiological mechanisms of social interaction from infancy to adulthood; and (4) formal and statistical issues in structural equation modelling, with an emphasis on latent growth curve modelling. Graduate education and research at the Center profit greatly from cooperation with other institutions in Berlin and Potsdam as well as from national and international collaboration.     

Process components of the Implicit Association Test: a diffusion-model analysis

The authors present a diffusion-model analysis of the Implicit Association Test (IAT). In Study 1, the IAT effect was decomposed into 3 dissociable components: Relative to the compatible phase, (a) ease and speed of information accumulation are lowered in the incompatible phase, (b) more cautious speed-accuracy settings are adopted, and (c) nondecision components of processing require more time. Studies 2 and 3 assessed the nature of interindividual differences in these components. Construct-specific variance in the IAT relating to the construct to be measured (such as implicit attitudes) was concentrated in the compatibility effect on information accumulation (Studies 2 and 3), whereas systematic method variance in the IAT was mapped on differential speed-accuracy settings (Study 3). Implications of these dissociations for process theories of the IAT and for applications are discussed.     

Take a risk or proceed with caution: Prevention motivation moderates responses to near-loss events

A persistently pressing issue identified in the decision-making literature is that people not only fail to recognize the risks entailed in a near-loss event but also subsequently engage in further risk-taking. We contend in this paper that prevention motivation critically regulates decision-makers' responses to a near-loss. Across three studies, we found that high prevention-focused individuals perceive greater risks in a near-loss event and are subsequently less likely to take risks, compared with low prevention-focused individuals. This finding highlights the significance of applying a motivational perspective to studying decision-making and risk.     

Personality Research and Assessment in the Era of Machine Learning

The increasing availability of high-dimensional, fine-grained data about human behaviour, gathered from mobile sensing studies and in the form of digital footprints, is poised to drastically alter the way personality psychologists perform research and undertake personality assessment. These new kinds and quantities of data raise important questions about how to analyse the data and interpret the results appropriately. Machine learning models are well suited to these kinds of data, allowing researchers to model highly complex relationships and to evaluate the generalizability and robustness of their results using resampling methods. The correct usage of machine learning models requires specialized methodological training that considers issues specific to this type of modelling. Here, we first provide a brief overview of past studies using machine learning in personality psychology. Second, we illustrate the main challenges that researchers face when building, interpreting, and validating machine learning models. Third, we discuss the evaluation of personality scales, derived using machine learning methods. Fourth, we highlight some key issues that arise from the use of latent variables in the modelling process. We conclude with an outlook on the future role of machine learning models in personality research and assessment.

Burn-out

At first the concept of burnout will be critically reflected in the context of the discussion in a position paper of the German Society for Psychiatry Psychotherapy and Neurology. An investigation of preventive stress management interventions at the workplace will be reported. The treatment concept of the day clinic of the Department for Psychosomatic Medicine and Psychotherapy of the Munich-Harlaching hospital for occupational stress-related disorders will be presented. An empirical study of the effectiveness of this treatment will be reported comparing patients with occupational stress-related disorders (n?=?95) to other patients treated in the day clinic during the same time interval (n?=?154). Furthermore, a qualitative analysis of 102 patient charts with occupational stress-related disorders will be described. Two case histories typical for mental health disease with burnout syndrome are presented to illustrate the conclusions.     

Marital intimacy,family support,and secondary traumatization: A study of wives of veterans with combat stress reaction

Abstract

The main aim of the study was to assess the role of family variables in the process of secondary traumatization among wives of post-traumatic veterans. We compared a sample of 49 wives of Israeli veterans with combat stress reaction (CSR) from the 1982 Lebanon War with a sample of 31 wives of Israeli veterans who fought in the war without developing CSR. We assessed their psychological reactions to the war, their health status six years later, and their reported levels of marital intimacy and family support after the war. When compared with controls, wives of veterans with CSR reported more negative emotions and lower perceived intimacy after the war, and greater severity of psychiatric and somatic symptoms six years later. Results also indicate that the greater the perceived marital intimacy, the less the negative emotions wives of veterans with CSR felt after the war and the better their health status six years later. In addition, wives of veterans with CSR who reported having received more support from their families after the war reported more anxiety and hostility than wives who received less support. The roles of marital intimacy and family support in the process of secondary traumatization were discussed.
