Recalibration makes (the) perfect sense
Marc Ernst
Department of Cognitive Neuroscience, Bielefeld University and Max Planck Institute for Biological Cyberentics
Wednesday July 6, 2011, 4:00
Jessell room, (Senate House), University of London
Abstract
The brain receives information about the environment from all the sensory modalities, including vision, touch and audition. To efficiently interact with the environment, this information must eventually converge in the brain in order to form a reliable and accurate multimodal percept. This process is often complicated by the existence of noise at every level of signal processing, which makes the sensory information derived from the world imprecise and potentially inaccurate. There are several ways in which the nervous system may minimize the negative consequences of noise in terms of precision and accuracy. Two key strategies are to combine redundant sensory estimates and to utilize acquired knowledge about the statistical regularities of different sensory signals. In this talk, I elaborate on how these strategies may be used by the nervous system in order to obtain the best possible estimates from noisy sensory signals, such that we are able of efficiently interact with the environment. Particularly, I will focus on the learning aspects and how our perceptions are tuned to the statistical regularities of an ever-changing environment.

IP Seminar: The space of action

Talk at the Forum for Perception, Action and Senses (CenSes),
Institute of Philosophy, School of Advanced Study, University of London
Corrado Sinigaglia
Department of philosophy, University of Milan, Italy
Thursday June 2, 2011, 3:00pm
Room G37 (Senate House, Ground Floor) University of London
Abstract
There is a huge amount of evidence that in processing others’ actions we take advantage of the same motor resources that allow us to efficiently perform those actions, being such processing modulated by our own motor repertoire. In particular, several brain imaging studies have demonstrated that the richer is our motor repertoire the greater is our ability to make sense of others’ actions, understanding them from the inside as our own motor possibilities and not just from the outside as mere events going on in the external world (Rizzolatti and Sinigaglia 2010, Sinigaglia 2010). Despite their relevance, these studies only focused on what philosophers are used to calling «general abilities» as distinct from «specific abilities» (Mele 2002) – while the former encompass all the skills characterizing one’s own motor repertoire regardless of whether they can be effectively instantiated, the latter refer to what one is actually in the position to do, that is, to her own actual motor possibilities.

IP seminar: Colour categories and the caerulean line

Talk at the Forum for Perception, Action and Senses, Institute of Philosophy, School of Advanced Study, University of London
John Mollon
Department of experimental psychology, Cambridge,

STB8 (Stewart House, Basement) University of London, Malet Street
Abstract
Colour perception offers clear examples of mental categories, but for more than twenty years colour scientists have been troubled by the fact that the red/green and blue/yellow axes of phenomenological colour space do not correspond to the two chromatically-opponent neural channels that have been identified in the primate visual system. One possibility is that we should seek the perceptually pure, or ‘unique’, hues not within ourselves but in the outside world: the locus in colour space of hues that are neither reddish nor greenish corresponds rather tightly to the locus of mixtures of natural illuminants, mixtures of sunlight and skylight. However, recent psychophysical results, obtained in collaboration with Dr. M. Danilova, suggest that there may after all be a neural channel that corresponds to the red-green axis of subjective colour space. Certainly, discrimination along this axis offers a robust example of superior discrimination at a category boundary.
IP Seminar: Impact of Crossmodal Transfer of Musical Emotion on Decision Making

Center for Cognition, Computation and Culture, Department of Psychology, Goldsmiths
STB8, Stewart House (basement), University of London
Abstract
We take decision at every step in our lives. It ranges from mundane perceptual decisions to complex cognitive ones. Classically our decision making process is considered as rational; emotion plays no role. But recent evidence suggests that decision making is a process guided by emotions. In this talk I will explore this topic by presenting results of several studies on crossmodal emotional priming by musical excerpts.
