Implicit Perception Simplicity and Explicit Perception Complexity in Sensorimotor Comunication

2019

Full-body illusions and minimal phenomenal selfhood.

2008

We highlight the latest research on body perception and self-consciousness, but argue that despite these achievements, central aspects have remained unexplored, namely, global aspects of bodily self-consciousness. Researchers investigated central representations of body parts and actions involving these, but neglected the global and unitary character of self-consciousness, the ‘I’ of experience and behaviour. We ask, what are the minimally sufficient conditions for the appearance of a phenomenal self, that is, the fundamental conscious experience of being someone? What are necessary conditions for self-consciousness in any type of system? We offer conceptual clarifications, discuss recent e…

How does the brain encode epistemic reliability? Perceptual presence, phenomenal transparency, and counterfactual richness

2014

AbstractSeth develops a convincing and detailed internalist alternative to the sensorimotor-contingency theory of perceptual phenomenology. However, there are remaining conceptual problems due to a semantic ambiguity in the notion of “presence” and the idea of “subjective veridicality.” The current model should be integrated with the earlier idea that experiential “realness” and “mind-independence” are determined by the unavailability of earlier processing stages to attention. Counterfactual richness and attentional unavailability may both be indicators of the overall processing level currently achieved, a functional property that normally correlates with epistemic reliability. Perceptual p…

Panel Summary Perceptual Learning and Discovering

1994

The problem of learning and discovering in perception is addressed and discussed with particular reference to present machine learning paradigms. These paradigms are briefly introduced by S. Gaglio. The subsymbolic approach is addressed by S. Nolfi, and the role of symbolic learning is analysed by F. Esposito. Many of the open problems, that are evidentiated in the course of the panel, show how this is an important field of research that still needs a lot of investigation. In particular, as a result of the whole discussion, it seems that a suitable integration of different approaches must be accurately investigated. It is observed, in fact, that the weakness of the most part of the existing…

Exploring Sensory Memories

2019

Lee Strasberg and other acting teachers developed sense memory exercises that teach an artistic re-enactment method to explore the interplay of sensory perception and emotional memory.
 Apparently, secondary sensory stimuli often trigger flashbacks for traumatised people. From my experience as an actress, I learned that the sense memory method is a controlled triggering of emotional memory that functions in the same way. Many anthropologists consider sensory experiences and emotions a relevant topic, but how can we teach students to deal with these phenomena?
 After looking at sense memory exercises against the backdrop of neuroscientific findings, I will consider why and how we s…

Commentary on Jakab's “Ineffability of Qualia”

2000

Zoltan Jakab has presented an interesting conceptual analysis of the ineffability of qualia in a functionalist and classical cognitivist framework. But he does not want to commit himself to a certain metaphysical thesis on the ontology of consciousness or qualia. We believe that his strategy has yielded a number of highly relevant and interesting insights, but still suffers from some minor inconsistencies and a certain lack of phenomenological and empirical plausibility. This may be due to some background assumptions relating to the theory of mental representation employed. Jakab's starting assumption is that there is no linguistic description of a given experience such that understanding t…

A cognitive architecture for inner speech

2020

Abstract A cognitive architecture for inner speech is presented. It is based on the Standard Model of Mind, integrated with modules for self-talking. Briefly, the working memory of the proposed architecture includes the phonological loop as a component which manages the exchanging information between the phonological store and the articulatory control system. The inner dialogue is modeled as a loop where the phonological store hears the inner voice produced by the hidden articulator process. A central executive module drives the whole system, and contributes to the generation of conscious thoughts by retrieving information from long-term memory. The surface form of thoughts thus emerges by …

Imitation Learning and Anchoring through Conceptual Spaces

2007

In order to have a robotic system able to effectively learn by imitation and not merely reproduce the movements of a human teacher, the system should have the capability to deeply understand the perceived actions to be imitated. This paper deals with the development of a cognitive architecture for learning by imitation in which a rich conceptual representation of the observed actions is built. The purpose of the following discussion is to show how the same conceptual representation can be used both in a bottom-up approach, in order to learn sequences of actions by imitation learning paradigm, and in a top-down approach, in order to anchor the symbolical representations to the perceptual act…

A cognitive architecture for music perception exploiting conceptual spaces

2015

A cognitive architecture for a musical agent is presented. The architecture extends and complete an architecture for computer vision previously developed by the author by taking into account many relationships between vision and music perception. The focus of the agent architecture is an intermediate conceptual area between the subconceptual and linguistic areas. A conceptual space for the perception of tones and intervals is thus presented, based on the dissonance measure of the tones. Problems and future works of the proposed approach are finally discussed.

Explorations on interactive interfaces using cuteness

2007

The experience of interactive systems can be a rather complex set of events. The perceptions appeal to the user's senses including visual, auditory, tactile, olfactory, and gustatory. Taken from a human factors approach, the sensitivity of the senses can be measured very closely and units of measurement arise from the "just noticeable difference." These differences can be mapped to the physics behind the stimuli and computer controlled systems very accurately provide sensation to the user through various user interfaces. The human mind also plays an important role in making sense of the experience not only from a physiological standpoint, but from a psychological and cultural reference poin…
