Young children’s protest: what it can (not) tell us about early normative understanding

In this paper we address the question how children come to understand normativity through simple forms of social interaction. A recent line of research suggests that even very young children can understand social norms quite independently of any moral context. We focus on a methodological procedure developed by Rakoczy et al., Developmental Psychology, 44, 875-881, that measures children's protest behaviour when a pre-established constitutive rule has been violated. Children seem to protest when they realize that rule violations are not allowed or should not have happened. We point out that there is more than one possible explanation for children's reactions in these studies. They could be due to disobeying an authority, an inability to follow a rule, or the violation of an empirical expectation due to the mismatch between statement and action. We thus question whether it would still count as an indicator for normative understanding if children responded to aspects of the game other than the violation of a constitutive rule and conclude that the protesting behavior, when taken in isolation, does not suffice as evidence for normative understanding

O Conhecimento de Fenômenos Psíquicos em Brentano

Das Hauptziel dieses Artikels ist es zu klären, wie Brentano das Verhältnis zwischen der Erkenntnis unserer eigenen Bewusstseinsphänomene und der Erkenntnis von Bewusstseinsphänomenen bei anderen Subjekten bestimmt. Brentano argumentiert der neuzeitlichen Tradition folgend zum einen dafür, dass die Erkenntnis eigener psychischer Akte absolut grundlegend ist. Zugleich möchte er mit seiner Psychologie vom empirischen Standpunkte aber eine Alternative zum Introspektionismus aufzeigen. Wir zeigen, wie Brentano diese beiden Ziele zu vereinen sucht und wie er auch in seiner Deskriptiven Psychologie an dieser Linie festgehalten hat. Seine Psychologie kann daher insgesamt als ein Plädoyer für einen erkenntnistheoretischen Pluralismus verstanden werden.O objetivo principal deste artigo é esclarecer como Brentano define a relação entre (a) o conhecimento de nossos próprios fenômenos de consciência e (b) o conhecimento de fenômenos de consciência de outros sujeitos. Por um lado, Brentano argumenta, seguindo a tradição moderna, que o conhecimento dos próprios atos mentais é absolutamente fundamental. Ao mesmo tempo, porém, ele quer mostrar com sua Psicologia do ponto de vista empírico uma clara alternativa ao introspeccionismo. Mostraremos como Brentano busca unir estes dois objetivos e como ele também aderiu a esta linha em sua Psicologia Descritiva. Sua psicologia como um todo pode, portanto, ser entendida como um apelo ao pluralismo epistemológico

Integrated photonic-based coronagraphic systems for future space telescopes

The detection and characterization of Earth-like exoplanets around Sun-like stars is a primary science motivation for the Habitable Worlds Observatory. However, the current best technology is not yet advanced enough to reach the 10^-10 contrasts at close angular separations and at the same time remain insensitive to low-order aberrations, as would be required to achieve high-contrast imaging of exo-Earths. Photonic technologies could fill this gap, potentially doubling exo-Earth yield. We review current work on photonic coronagraphs and investigate the potential of hybridized designs which combine both classical coronagraph designs and photonic technologies into a single optical system. We present two possible systems. First, a hybrid solution which splits the field of view spatially such that the photonics handle light within the inner working angle and a conventional coronagraph that suppresses starlight outside it. Second, a hybrid solution where the conventional coronagraph and photonics operate in series, complementing each other and thereby loosening requirements on each subsystem. As photonic technologies continue to advance, a hybrid or fully photonic coronagraph holds great potential for future exoplanet imaging from space.Comment: Conference Proceedings of SPIE: Techniques and Instrumentation for Detection of Exoplanets XI, vol. 12680 (2023

Visible extreme adaptive optics on extremely large telescopes: Towards detecting oxygen in Proxima Centauri b and analogs

Looking to the future of exo-Earth imaging from the ground, core technology developments are required in visible extreme adaptive optics (ExAO) to enable the observation of atmospheric features such as oxygen on rocky planets in visible light. UNDERGROUND (Ultra-fast AO techNology Determination for Exoplanet imageRs from the GROUND), a collaboration built in Feb. 2023 at the Optimal Exoplanet Imagers Lorentz Workshop, aims to (1) motivate oxygen detection in Proxima Centauri b and analogs as an informative science case for high-contrast imaging and direct spectroscopy, (2) overview the state of the field with respect to visible exoplanet imagers, and (3) set the instrumental requirements to achieve this goal and identify what key technologies require further development.Comment: SPIE Proceeding: 2023 / 12680-6

Teleology first: goals before knowledge and belief

Comparing knowledge with belief can go wrong in two dimensions: If the authors employ a wider notion of knowledge, then they do not compare like with like because they assume a narrow notion of belief. If they employ only a narrow notion of knowledge, then their claim is not supported by the evidence. Finally, we sketch a superior teleological view
