The effects of coverage, similarity measures, and cluster overlap were studied by including different levels of coverage for the hierarchical algorithms, Euclidean distances and Pearson correlation coefficients, and truncated multivariate normal mixtures in the analysis. The results confirmed the findings of previous Monte Carlo studies on clustering procedures in that accuracy was inversely related to coverage, and that algorithms using correlation as the similarity measure were significantly more accurate than those using Euclidean distances. No evidence was found for the assumption that the positive effects of the use of correlation coefficients are confined to unconstrained mixture models.}, subject = {Psychologie}, language = {en} } @article{SchneiderTreiber1984, author = {Schneider, Wolfgang and Treiber, Bernhard}, title = {Classroom differences in the determination of achievement changes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-61991}, year = {1984}, abstract = {This study addresses three themes that recur in the research on student achievement: (a) developmental modeling ofintraindividual changes in achievement over time; (b) examination of the differences among subgroups within a classroom in the determinants of achievement; (c) description of the interactions among instructional variables in determining achievement differences. Eight classrooms were preselected on the basis of their widely differing slopes obtained in a regression analysis of pre- and posttest achievement scores. Mathematics achievement differences among sixth graders were analyzed in a four-wave design and explained by aptitude and instructional variables in a structural equation framework provided by LISREL. The results demonstrate the local nature of achievement models in that neither their measurement nor structural components proved generalizable across both groups of classrooms. Mention is also made, however, of technical problems and analytical ambiguities in the interpretation of these results.}, subject = {Psychologie}, language = {en} } @incollection{Ellgring1984, author = {Ellgring, Johann Heinrich}, title = {The study of nonverbal behavior and its applications: State of the art in Europe}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-42997}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1984}, abstract = {No abstract available}, language = {en} } @incollection{Krueger1983, author = {Kr{\"u}ger, Hans-Peter}, title = {What differentiates a differential psychopharmacology?}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-41248}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1983}, abstract = {The methodological implications of a differential psychopharmacology are discussed. It is shown that the technique of stratifying subjects with personality scores depends on one basic assumption: the personality score is not affected by the other experimental factors. Two experiments are reported in which pre- and posttest (after the experiment) scores were measured. The pre-post-differences showed themselves to be affected by the medication. It is argued that in psychopharmacological experimentation an additional step must be included. All non-treatment factors must be examined for their stability in the course of the experiment. If they are stable, usual evaluation may take place. If changes are attributable to the treatment, personality scores must be regarded as dependent variables. They have to be evaluated together with the other observables with a multivariate model.

In Study 1, the ability to integrate the probabilities and the payoffs of simple bets was examined using the rating scale methodology. Children's choices among three of those simple bets were recorded also. By cross-classifying the children's choice and rating behavior it was shown that a three-stage developmental hypothesis of decision making is not sufficient. A four-stage hypothesis is proposed. In Study 2, the influence of enlarging the presented number of alternatives from two to three and the influence of the similarity of the alternatives on children's choice probabilities was examined with those bets. Children's choice behavior was probabilistic and was influenced only by enlarging the presented number of alternatives. These results suggest that a Bayesian approach, based on two probabilistic choice models, should not be applied in order to analyze children's choice behavior. The functional measurement approach is, as was demonstrated in Study 1, a powerful implement to further the understanding of the development of decision making.}, subject = {Kognitive Entwicklung / Informationsverarbeitung / Kind / Informationsintegration}, language = {en} } @article{EderRothermundHommel, author = {Eder, Andreas B. and Rothermund, Klaus and Hommel, Bernhard}, title = {Commentary: Contrasting motivational orientation and evaluative coding accounts: on the need to differentiate the effectors of approach/avoidance responses}, series = {Frontiers in Psychology}, volume = {7}, journal = {Frontiers in Psychology}, number = {163}, issn = {1664-1078}, doi = {10.3389/fpsyg.2016.00163}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-190141}, abstract = {A commentary on "Contrasting motivational orientation and evaluative coding accounts: on the need to differentiate the effectors of approach/avoidance responses" by Kozlik, J., Neumann, R., and Lozo, L.

We aimed to investigate the evolution of psychosocial adjustment to ALS and to determine its long-term predictors. A longitudinal study design with four measurement time points was therefore, used to assess patients' quality of life, depression, and stress-coping model related aspects, such as illness characteristics, social support, cognitive appraisals, and coping strategies during a period of 2 years. Regression analyses revealed that 55\% of the variance of severity of depressive symptoms and 47\% of the variance in quality of life at T2 was accounted for by all the T1 predictor variables taken together. On the level of individual contributions, protective buffering, and appraisal of own coping potential accounted for a significant percentage in the variance in severity of depressive symptoms, whereas problem management coping strategies explained variance in quality of life scores. Illness characteristics at T2 did not explain any variance of both adjustment outcomes. Overall, the pattern of the longitudinal results indicated stable depressive symptoms and quality of life indices reflecting a successful adjustment to the disease across four measurement time points during a period of about two years. Empirical evidence is provided for the predictive value of social support, cognitive appraisals, and coping strategies, but not illness parameters such as severity and duration for adaptation to ALS. The current study contributes to a better conceptualization of adjustment, allowing us to provide evidence-based support beyond medical and physical intervention for people with ALS.}, language = {en} } @article{StrackPauliWeyers, author = {Strack, Fritz and Pauli, Paul and Weyers, Peter}, title = {Editorial: Emotion and Behavior}, series = {Frontiers in Psychology}, volume = {7}, journal = {Frontiers in Psychology}, number = {313}, issn = {1664-1078}, doi = {10.3389/fpsyg.2016.00313}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-190177}, abstract = {No abstract available.}, language = {en} } @article{SchumannSteinbornKuertenetal., author = {Schumann, Frank and Steinborn, Michael B. and K{\"u}rten, Jens and Cao, Liyu and H{\"a}ndel, Barbara Friederike and Huestegge, Lynn}, title = {Restoration of attention by rest in a multitasking world: theory, methodology, and empirical evidence}, series = {Frontiers in Psychology}, volume = {13}, journal = {Frontiers in Psychology}, issn = {1664-1078}, doi = {10.3389/fpsyg.2022.867978}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-267913}, abstract = {In this work, we evaluate the status of both theory and empirical evidence in the field of experimental rest-break research based on a framework that combines mental-chronometry and psychometric-measurement theory. To this end, we (1) provide a taxonomy of rest breaks according to which empirical studies can be classified (e.g., by differentiating between long, short, and micro-rest breaks based on context and temporal properties). Then, we (2) evaluate the theorizing in both the basic and applied fields of research and explain how popular concepts (e.g., ego depletion model, opportunity cost theory, attention restoration theory, action readiness, etc.) relate to each other in contemporary theoretical debates. Here, we highlight differences between all these models in the light of two symbolic categories, termed the resource-based and satiation-based model, including aspects related to the dynamics and the control (strategic or non-strategic) mechanisms at work. Based on a critical assessment of existing methodological and theoretical approaches, we finally (3) provide a set of guidelines for both theory building and future empirical approaches to the experimental study of rest breaks. We conclude that a psychometrically advanced and theoretically focused research of rest and recovery has the potential to finally provide a sound scientific basis to eventually mitigate the adverse effects of ever increasing task demands on performance and well-being in a multitasking world at work and leisure.}, language = {en} }
