Title: Learning and Understanding
Abstract:There is a certain Kantian conception of perceptual experience on which experience can only present those aspects of the world which we already understand (for example, can only present trees qua trees if we understand what a tree is). McDowell has famously argued that it is only by accepting this Kantian conception that we can allow for a highly desirable kind of openness to the world, such that objects in the world can be genuine reasons for our beliefs and actions. Unfortunately this same Kantian conception appears to rule out another very desirable kind of openness: openness to that which we do not yet understand. In this paper, I argue that this problem is only apparent. Even if experience can only present that which we understand, nevertheless we can already understand – from within such a framework, as it were – that the world is not behaving consistently with our expectations. This indicates that something new is required. In any normal case, this lack of coherence with our expectations will never be total, thus we can map out the extent of our lack of understanding. The ‘shape’ of our lack of understanding (which we find by exploring the world) can guide us. In all this, past experience can only ever be a partial guide: luck (in more reductive terms, random exploration) is required, as well as judgment. Using both luck and judgment, we may arrive at some new candidate framework of understanding. At this point no more luck is required, good judgment alone (applied as we interact with the world) can tell us whether or not a new candidate framework is better for our purposes than our old framework. This way of describing things pulls apart what is in reality a fluid process, but nevertheless points to key features of that process. The transitions made in such a process are genuinely rational: they are made by the perceiver, for the perceiver’s own reasons. Thus, it is concluded, we do not need to step outside the framework of practical, engaged rationality in order to analyse perceptual openness to aspects of the world which a perceiver has not yet understood.

Title: The Autonomies of Bioethics
Abstract: This presentation begins with a set of distinctions between differents concepts (or families of concepts) of autonomy that are present in the theory and practice of bioethics. My porpuse is to examine how the principle of autonomy works in two different branches of bioethics, health care ethics on the one hand, characterized by the dependence of patients and users of health services, and research ethics on the other, marked by the vulnerability of the subjects. Although differents fields (health care is not a science but a practice or art, while biomedical research does aspire to be scientific), I transfer some intuitions from the first to the second field, especially those emphasizing the interactive and relational nature of autonomy. The fact that autonomy is always relational is more easily seen in healthcare ethics, but not so much in research ethics. Despite that autonomy in research ethics is more formal and less personal, I defend that it needs integrate certain aspects of healtcare, which mainly affect how we understand the autonomy of the patient or research subject in relation to the clinicians or researchers who are treating them.

Title: Habits as sensorimotor life-forms: modelling self-maintaining behaviour with an iterant deformable sensorimotor medium
Abstract: Artificial Life has not yet explored in depth the analogy between life and mind that is hidden in the nature of habits: their self-sustaining dissipative structure as ecological sensorimotor entities. We present a new dynamical model for habits implementing what we call a node-based “iterant deformable sensorimotor medium” (IDSM). The IDSM has properties designed such that trajectories taken through state space increase the likelihood that in the future, similar trajectories will be taken. We couple the IDSM to sensors and motors of a simulated body in a simulated environment and show that under certain conditions, the IDSM resonates with the other parts of the simulation, forming self-maintaining patterns of activity operating over the IDSM, the body, and the environment. These patterns of activity are similar in many respects to habits, patterns of activity that are self-reinforced. We present various environments and the resulting ‘habits’ that form in them, studying the sensorimotor coordination patterns that stabilize in the process. We discuss how this model and extensions of it can help us understand and model self-sustaining patterns of behaviour as building blocks for a theory of cognition that does no rely on representations

Title: Towards a Scientifically Tractable, Direct Realist, Sensorimotor Account of Experience
Abstract: The sensorimotor account of experience has arguably not lived up to its early promise. I suggest that this is because a full-blown sensorimotor account needs to reject an assumption shared by most consciousness researchers, namely that first person experience corresponds to processes in the head. I argue instead that when we are experiencing an object or property in the world, the experienced object is literally part of the subjective experience. This is a form of direct realism. The sensorimotor account shows us (in ways which can be made highly analytic and mathematical) what objects are, such that we may enact them, and what experience is, such that it may directly, constitutively involve these external objects. This externalist account of experience matches our first-person phenomenology much better than the standard, internalist view; it also makes it much clearer how we can have genuine knowledge of the external world. Action-based views of perception, such as this one, should respond to apparently problematic cases such as locked-in syndrome, not by referring to covert action, but rather by referring to counterfactual links to overt action (this use of counterfactuals is completely normal in science). Direct realist views should respond to arguments from illusion by noting that the detailed flow of subjective experience is different when we are really encountering an object, and when we only seem to be. Brain dynamics remain a crucial enabling part of experience, but not the only part; experience itself is the ongoing, meaningful relationship between subject and world.

Dr. Hiro Iizuka will be giving a talk on «Emergence of Turn-taking Behaviour on Agency Detection Simulation and Behavioural Turing Test Experiment.»
Date and place: 4th September 2012, at 14.30, Room B1, Carlos Santamaría Building.
Abstract: In this talk, I will talk about a simulation study for agency detection and human experiments for behavioural turing test. These are recent results of series of my work using perceptual crossing paradigm where the interaction of agents or humans is restricted into simple sensor and motor. In the agency detection it is investigated how the embodied agents can establish a live interaction and discriminate this from interactions from recorded motions that are identical to the live interaction but cannot react contingently. In the behavioural turing test, it is investigated how the human can discriminate with the non-human moving objects. Both studies support that the turn-taking behaviour plays an important role to achieve the tasks and we will see how the simple embodied interaction can evolve to communicative interaction.
