A general proof of consistency of heuristic classification for cognitive diagnosis models

The Asymptotic Classification Theory of Cognitive Diagnosis (Chiu et al., 2009, Psychometrika, 74, 633–665) determined the conditions that cognitive diagnosis models must satisfy so that the correct assignment of examinees to proficiency classes is guaranteed when non‐parametric classification methods are used. These conditions have only been proven for the Deterministic Input Noisy Output AND gate model. For other cognitive diagnosis models, no theoretical legitimization exists for using non‐parametric classification techniques for assigning examinees to proficiency classes. The specific statistical properties of different cognitive diagnosis models require tailored proofs of the conditions of the Asymptotic Classification Theory of Cognitive Diagnosis for each individual model – a tedious undertaking in light of the numerous models presented in the literature. In this paper a different way is presented to address this task. The unified mathematical framework of general cognitive diagnosis models is used as a theoretical basis for a general proof that under mild regularity conditions any cognitive diagnosis model is covered by the Asymptotic Classification Theory of Cognitive Diagnosis.     

End-state comfort in bimanual object manipulation

The present experiment investigated the sensitivity for end-state comfort in a bimanual object manipulation task. Participants were required to simultaneously reach for two bars and to place the objects' ends into two targets on the table. The design of the experiment allowed to dissociate the relative roles of initial means (e.g., the selection of grips) and final postures (e.g., the anticipation of end-states). The question of interest was whether affording different grip patterns for the two hands would introduce a bias away from reaching end-state comfort. Results revealed a strong sensitivity for end-state comfort, independent of the required grip patterns. In particular, end-state comfort was preferred even if this meant selecting different initial means (i.e., different grips) for the two hands. Hence, end-state oriented action planning appears to dominate interaction costs that may result from motor-related, intermanual interference. We infer that movement planning is constrained by action goals (e.g., a comfortable end-posture for both hands), but largely unaffected by the type of motor actions necessary to achieve these goals.     

Child social skills training in developmental crime prevention: effects on antisocial behavior and social competence

Social skills training for children is becoming increasingly popular as a measure for developmental crime prevention. Although previous reviews of such programs have shown positive effects, they have also revealed problems of research design, outcome measures, and long-term follow up. Accordingly, this article reports on a recent meta-analysis of randomized evaluations of the effect of social skills training in preventing antisocial behavior and promoting social competence. Of 841 retrievable references, 84 research reports with a total of 136 treatment-control comparisons fulfilled the eligibility criteria. Results showed a small but significant overall positive effect of d = .39 at post-intervention and d = .28 at follow-up (3 months and later). Effect sizes were somewhat greater for outcome measures of social competence than for measures of antisocial behavior, particularly when delinquency was assessed. Cognitive-behavioral programs revealed the best results in terms of generalization over time and on outcome criteria. In addition, prevention measures indicated for children and adolescents who already manifested some behavioral problems had higher effect sizes than universal approaches. Because most studies dealt with small sample sizes, non-official outcome data, and measurements after less than one year, the results should be interpreted with caution. Further high-quality studies with long-term empirical outcome criteria are needed, particularly outside the United States.     

The selection of creative ideas after individual idea generation: Choosing between creativity and impact

It is commonly assumed that successful innovation depends on creative idea generation: the more ideas are generated, the higher the probability of selecting a very good idea should be. However, research has shown that people do not perform optimally at idea selection and that ideational output may not contribute much to creative idea selection. The present studies aim to explain this phenomenon. We identified the strong tendency of our participants to select feasible and desirable ideas, at the cost of originality, as the main reason for their poor selection performance. Two manipulations of participants' processing of the available ideas (exclusion instructions and quality ratings) had no effect on selection effectiveness. In contrast, explicitly instructing participants to select creative or original ideas did improve selection effectiveness with regard to idea originality, but at the same time decreased participants' satisfaction and the rated effectiveness of chosen ideas. Results are discussed in relation to an effectiveness‐originality trade off.     

Quality of Life in the European Union and the United States of America: Evidence from Comprehensive Indices

The main question of this article is about the quality of life in the European Union and the United States measured by different comprehensive indicators (HDI, WBI, WISP, OLS, PWI, ABS, HLE). On the world scale moderately different levels of quality of life characterize the European Area and the US. In objective terms, the US is more at the top level regarding economy and science, whereas Europe is more at the top level regarding social concerns in a broad sense. In subjective terms, which means to rely on the usual subjective measures, the average of US population seems to be slightly better off than the average of the EU population. That said, the differences inside the EU are often more significant than those between the EU and the US. Many EU countries in Northern and Western Europe show higher satisfaction levels than the US, and Eastern Europe is especially low in respect to the satisfaction of its population. It is rather obvious that the choice of criteria and values influences the results of the comparisons of nations and supranational unions to a considerable degree.     

A Non-Verbal Technique for Assessing Frustration Response in Pre-School Children

The present study represents a report of the initial development of a picture method for assessing response to frustration in preschool children. Study 1 (N = 91) included the initial development of the picture materials; it also produced some validational support for the picture method in the form of significant correlations between picture choices and extensive behavior observations. Study 2 (N = 49) was designed to be essentially a replication of Study 1. In addition, further validational support was sought through the correlation of picture choices with global teacher ratings of the behaviors of interest.     

Dynamic Simulation and Static Matching for Action Prediction: Evidence From Body Part Priming

Accurately predicting other people's actions may involve two processes: internal real‐time simulation (dynamic updating) and matching recently perceived action images (static matching). Using a priming of body parts, this study aimed to differentiate the two processes. Specifically, participants played a motion‐controlled video game with either their arms or legs. They then observed arm movements of a point‐light actor, which were briefly occluded from view, followed by a static test pose. Participants judged whether this test pose depicted a coherent continuation of the previously seen action (i.e., “action prediction task”). Evidence of dynamic updating was obtained after compatible effector priming (i.e., arms), whereas incompatible effector priming (i.e., legs) indicated static matching. Together, the results support action prediction as engaging two distinct processes, dynamic simulation and static matching, and indicate that their relative contributions depend on contextual factors like compatibility of body parts involved in performed and observed action.
