Cognitive flexibility, the adaptation of representations and responses to new task demands, improves dramatically in early childhood. It is unclear, however, whether flexibility is a coherent, unitary cognitive trait, or is an emergent dimension of task-specific performance that varies across populations with divergent experiences. Three-to 5-year-old English-speaking U.S. children and Tswana-speaking South African children completed two distinct language-processing cognitive flexibility tests: the FIM-Animates, a word-learning test, and the 3DCCS, a rule-switching test. U.S. and South African children did not differ in (...) word-learning flexibility but showed similar age-related increases. In contrast, U.S. preschoolers showed an age-related increase in rule-switching flexibility but South African children did not. Verbal recall explained additional variance in both tests but did not modulate the interaction between population sample (i.e., country) and task. We hypothesize that rule-switching flexibility might be more dependent upon particular kinds of cultural experiences, whereas word-learning flexibility is less cross-culturally variable. (shrink)

Experiments in particle physics have hitherto failed to produce any significant evidence for the many explicit models of physics beyond the Standard Model (BSM) that had been proposed over the past decades. As a result, physicists have increasingly turned to model-independent strategies as tools in searching for a wide range of possible BSM effects. In this paper, we describe the Standard Model Effective Field Theory (SM-EFT) and analyse it in the context of the philosophical discussions about models, theories, and (bottom-up) (...) effective field theories. We find that while the SM-EFT is a quantum field theory, assisting experimentalists in searching for deviations from the SM, in its general form it lacks some of the characteristic features of models. Those features only come into play if put in by hand or prompted by empirical evidence for deviations. Employing different philosophical approaches to models, we argue that the case study suggests not to take a view on models that is overly permissive because it blurs the lines between the different stages of the SM-EFT research strategies and glosses over particle physicists' motivations for undertaking this bottom-up approach in the first place. Looking at EFTs from the perspective of modelling does not require taking a stance on some specific brand of realism or taking sides in the debate between reduction and emergence into which EFTs have recently been embedded.

La citazione di Rilke pare ben delineare gli ambiti “abissali” del rapporto di noi tutti con “Dio”, di “Dio” con l'abisso di se stesso, come Jung (ma non solo) ritiene, e in definitiva di noi stessi con noi stessi (Jung: ”L'uomo moderno deve perciò trovare altrove, nel suo profondo, le sorgenti della propria vita spirituale, e per trovarle deve individualmente lottare contro il male, confrontarsi con l'Ombra, integrare il demonio”). Il libro di Giobbe appare configurarsi come lo sforzo ultimo di (...) Jung di legare vertiginosamente ma molto plausibilmente appunto, riflessioni complesse sulla natura del male, sul rapporto (sempre al limite del comprensibile e del dicibile) tra monismo e dualità, che “dall'Alto dei Cieli” tombe nell'inconscio, su eventi simbolici come la assumptio Mariae, sui simboli dell'imago dei.. Lo scopo del presente lavoro è il breve e non completo affresco della possibile correlazione tra il Libro di Giobbe e alcuni antecedenti mesopotamici, nel senso di riflettere su alcuni possibili differenti simbolismi sottesi a questa correlazione, che sembrano avvallare la lettura junghiana, ma anche di mostrare una plausibile convergenza dell'interpretazione junghiana del testo con altre formulazioni teoriche.
