Forever off? Status śmierci podmiotu posthumanistycznego w mediach cyfrowych
Get PDFKatherine Hayles zdefiniowała postczłowieka jako rozszerzony system poznawczy, który umieszczony jest w „cybernetycznym obwodzie, który przeplata jego wolę, pragnienia i percepcję”. Tak określona kategoria postczłowieka nie stanowi projektu czy hipotezy, ale opis otaczającej nas rzeczywistości, w której wszyscy jesteśmy always on, dzieląc swoje życie między rzeczywistość a świat wirtualny. Jednym z problemów, jakie rodzi taki stan rzeczy, jest definicja „śmierci” w mediach cyfrowych – gdzie to, co do tej pory stanowiło poszerzenie człowieka – profil na Facebooku, konto na forum – „żyje” nawet po śmierci swojego właściciela. Przedmiotem artykułu jest analiza tego fenomenu poprzez kategorię użytkownika forever off, opartą na wypracowanej na gruncie współczesnej posthumanistycznej filozofii analizie śmierci (Rosi Braidotti).Filip Lohne

Modeling "spatial purport of perceptual experience": egocentric space perception in a semi-realistic 3D virtual environment
Get PDFEgocentric space perception is multimodal, closely tied to action and bodily movements and has an inherent phenomenal dimension. One prominent account, provided by Rick Grush, has postulated posterior parietal cortex as key neural area. Computational model based on Kalman filter has been proposed to account for the operation of this brain region, underscoring the importance of bodily skills for perceiving spatial properties.
The current study provides a first direct simulation of this model in a semi-realistic 3D virtual environment. The goal of the simulation was to develop an agent with a realistic ability for egocentric space perception based on a neural approximation of Kalman filter. To achieve this goal, we use machine learning techniques, with a strong focus on unsupervised methods of reinforcement learning.
Resulting agent is tested behaviorally on ecologically plausible tasks to evaluate its internal, learned representations. Poster presents simulation results and discusses the model

Counting with Cilia: The Role of Morphological Computation in Basal Cognition Research
No full text“Morphological computation” is an increasingly important concept in robotics, artificial intelligence, and philosophy of the mind. It is used to understand how the body contributes to cognition and control of behavior. Its understanding in terms of "offloading" computation from the brain to the body has been criticized as misleading, and it has been suggested that the use of the concept conflates three classes of distinct processes. In fact, these criticisms implicitly hang on accepting a semantic definition of what constitutes computation. Here, I argue that an alternative, mechanistic view on computation offers a significantly different understanding of what morphological computation is. These theoretical considerations are then used to analyze the existing research program in developmental biology, which understands morphogenesis, the process of development of shape in biological systems, as a computational process. This important line of research shows that cognition and intelligence can be found across all scales of life, as the proponents of the basal cognition research program propose. Hence, clarifying the connection between morphological computation and morphogenesis allows for strengthening the role of the former concept in this emerging research field
Looking for keys in model organisms: Interpreting and keying-up in basal cognition
Get PDFIn this article, I analyse what epistemic operations are involved in adopting novel model organisms in a given research field. To this end, I draw on the DEKI account of scientific representation, and extend it by introducing the notions of "interpretation-" and "key-sketches". These refer to the incomplete and heuristically-justified mappings between models and targets that are initially constructed while the model is being developed for a particular use. I substantiate this proposal by analysing three case studies coming from the emerging research area of basal cognition, where an established model organism is adopted for novel uses in the context of neuroscientific research
