The article discusses the allegedly decontextualized and ahistorical traits in positivist educational research and curriculum by examining its emergence in early twentieth-century empirical education. Edward Lee Thorndike’s educational psychology is analyzed as a case in point. It will be shown that Thorndike’s positivist educational psychology stressed the need to account for the reality of schooling and to produce knowledge of the actual contexts of education. Furthermore, a historical analysis informed by Michel Foucault’s history of the human sciences reveals that there (...) are multiple historical temporalities involved in Thorndike’s educational psychology. This allows a new critical angle to be taken on positivist educational research. The question concerning the contexts of empirical education turns to examining the way the conditions of possibility for scientific knowledge in education involve practices of contextualization as well as paradoxical and self-defeating elements.

Why does performing certain tasks cause the aversive experience of mental effort and concomitant deterioration in task performance? One explanation posits a physical resource that is depleted over time. We propose an alternative explanation that centers on mental representations of the costs and benefits associated with task performance. Specifically, certain computational mechanisms, especially those associated with executive function, can be deployed for only a limited number of simultaneous tasks at any given moment. Consequently, the deployment of these computational mechanisms carries (...) an opportunity cost – that is, the next-best use to which these systems might be put. We argue that the phenomenology of effort can be understood as the felt output of these cost/benefit computations. In turn, the subjective experience of effort motivates reduced deployment of these computational mechanisms in the service of the present task. These opportunity cost representations, then, together with other cost/benefit calculations, determine effort expended and, everything else equal, result in performance reductions. In making our case for this position, we review alternative explanations for both the phenomenology of effort associated with these tasks and for performance reductions over time. Likewise, we review the broad range of relevant empirical results from across sub-disciplines, especially psychology and neuroscience. We hope that our proposal will help to build links among the diverse fields that have been addressing similar questions from different perspectives, and we emphasize ways in which alternative models might be empirically distinguished.

To handle complex technical operations, operators acquire skills in vocational training. Most of these skills are not used immediately but at some point later; this is called temporal transfer. Our previous research showed that cognitive abilities such as general mental ability and memory are good predictors of temporal transfer. In addition to temporal transfer, operators also have to solve non-routine and abnormal upcoming problems using their skill set; this type of transfer is called adaptive transfer. Based on previous findings, it (...) is assumed that GMA and memory will affect adaptive transfer as well. Thirty-three engineering students learned how to operate a complex technical system in normal operation with either a fixed or a contingent sequence. After two weeks, all participants had to adapt their learned skills to handle the adaptive transfer task, which was not initially trained. It was shown that high GMA positively predicted adaptive transfer, but no effect of memory was found. This implies that GMA is required to solve new complex tasks using a learned skill set. The findings are in line with studies that showed an effect of GMA on temporal transfer. (shrink)

Science requires postformal capabilities to compare competing explanations and conceptualize how to coordinate or integrate them. With conflicts thus reconciled, science advances. The Model of Hierarchical Complexity facilitates the coordination of current arguments about intelligence. A cross-species measurement theory of comparative cognition is proposed. It has potential to overcome the lack of a general measurement theory for the science of comparative cognition, and the lack of domain-general mechanisms for evolutionary psychologists. The hierarchical complexity of concepts and debates as well as (...) the new theory are scored, and demonstrate the postformal hierarchical complexity of the proposed theory. (shrink)

In this paper I explore an underdiscussed factor contributing to the replication crisis: Scientists, and following them policy makers, often neglect sources of errors in the production and interpretation of data and thus overestimate what can be learnt from them. This neglect leads scientists to conduct experiments that are insufficiently informative and science consumers, including other scientists, to put too much weight on experimental results. The former leads to fragile empirical literatures, the latter to surprise and disappointment when the fragility (...) of the empirical basis of some disciplines is revealed. (shrink)

Le psychologue français Alfred Binet est à l'origine du développement de tests mentaux destinés à diagnostiquer le « niveau intellectuel » des enfants. Initialement conçus comme des tests cliniques, leur importation aux États-Unis dans les années 1910 a considérablement modifié leur usage, leur portée pratique et leur interprétation. Devenus les instruments de politiques eugéniques ou héréditaristes, utilisés dans des processus de sélection de grande échelle, les tests ont transformé la conception que les psychologues se faisaient de l'intelligence: initialement conçue comme (...) multiforme et qualitative, elle est devenue une grandeur unique quantifiable. C'est dans ce contexte que le psychologue américain Louis Léon Thurstone, critiquant le manque de rigueur des méthodes statistiques utilisées dans les tests, a développé une nouvelle méthode permettant de disposer d'une unité et d'un zéro absolu pour la mesure (échelonnement) de l'intelligence. Une fois objectivée, sa méthode est devenue une « loi » générale permettant de rendre compte de tous les processus mentaux, de disposer d'un outil d'analyse des opinions et des attitudes. (shrink)

At some point the mechanics of schooling begin running of their own accord. Such has become the case with grades (A's, B's, C's, etc.). This article reconsiders the history of grades through the concepts of immanence and abstract machines from the oeuvre of Deleuze and Guattari. In the first section, the history of grades as presently written until now is laid out. In the second, the concepts of immanence and abstract machines are described, and in the third section, problems are (...) raised by reconsidering grades as machines (grade-machines). (shrink)
