"PERCEP" software for experiment control of temporal judgment research with humans

Um programa de computador, o "PERCEP", foi desenvolvido para a realização dos procedimentos experimentais de estimativa verbal, produção e reprodução temporal em seres humanos. Além da coleta de dados, o programa permite ao experimentador manipular diferentes parâmetros das tarefas e avaliar o impacto dessas manipulações sobre sua aquisição e desempenho. Uma vez que a configuração do programa "PERCEP" é definida pelo próprio experimentador, pode-se realizar uma ampla gama de experimentos acerca dos processos subjacentes ao julgamento temporal. O objetivo do presente trabalho é descrever este programa.A computer program - "PERCEP" - was developed for accomplishing the experimental procedures of verbal estimation, time production and reproduction in human beings. Besides the collection of data, the program allows the researcher to manipulate different parameters of tasks and to evaluate the impact of those manipulations on acquisition and performance. Once the configuration of the "PERCEP" program is defined by the researcher, a wide range of experiments concerning time judgment processing can take place. The aim of the present work is to describe this program

Perceived Vertical and Lateropulsion: Clinical Syndromes, Localization, and Prognosis

We present a clinical classification of central vestibular syndromes according to the three major planes of action of the vestibulo-ocular reflex: yaw, roll, and pitch. The plane-specific syndromes are determined by ocular motor, postural, and percep tual signs. Yaw plane signs are horizontal nystagmus, past pointing, rotational and lat eral body falls, deviation of perceived straight-ahead to the left or right. Roll plane signs are torsional nystagmus, skew deviation, ocular torsion, tilts of head, body, and perceived vertical in a clockwise or counterclockwise direction. Pitch plane signs are upbeat/downbeat nystagmus, forward/backward tilts and falls, deviations of the per ceived horizon. The thus defined vestibular syndromes allow a precise topographic analysis of brainstem lesions according to their level and side. Special emphasis is placed on the vestibular roll plane syndromes of ocular tilt reaction, lateropulsion in Wallenberg's syndrome, thalamic and cortical astasia and their association with roll plane tilt of perceived vertical. Recovery is based on a functionally significant central compensation of a vestibular tone imbalance, the mechanism of which is largely un known. Physical therapy may facilitate this central compensation, but this has not yet been proven in prospective studies

L'evolució dels sistemes d'ajuda a l'habitatge protegit de lloguer als països de la UE

Seguint principis polítics diversos, alguns estats de la Unió Europea col·loquen l'habitatge protegit de lloguer al marge de les realitats econòmiques del mercat; uns altres consideren que el lloguer que percep la propietat ha de permetre equilibrar l'explotació. Aquests dos models evolucionen cap a una racionalització

Re-examining Husserl’s Non-Conceptualism in the Logical Investigations

A recent trend in Husserl scholarship takes the Logische Untersuchungen (LU) as advancing an inconsistent and confused view of the non-conceptual content of perceptual experience. Against this, I argue that there is no inconsistency about non-conceptualism in LU. Rather, LU presents a hybrid view of the conceptual nature of perceptual experience, which can easily be misread as inconsistent, since it combines a conceptualist view of perceptual content (or matter) with a non-conceptualist view of perceptual acts. I show how this hybrid view is operative in Husserl’s analyses of essentially occasional expressions and categorial intuition. And I argue that it can also be deployed in relation to Husserl’s analysis of the constitution of perceptual fullness, which allows it to avoid a objection raised by Walter Hopp—that the combination of Husserl’s analysis of perceptual fullness with conceptualism about perceptual content generates a vicious regress

Up the nose of the beholder? Aesthetic perception in olfaction as a decision-making process

Is the sense of smell a source of aesthetic perception? Traditional philosophical aesthetics has centered on vision and audition but eliminated smell for its subjective and inherently affective character. This article dismantles the myth that olfaction is an unsophisticated sense. It makes a case for olfactory aesthetics by integrating recent insights in neuroscience with traditional expertise about flavor and fragrance assessment in perfumery and wine tasting. My analysis concerns the importance of observational refinement in aesthetic experience. I argue that the active engagement with stimulus features in perceptual processing shapes the phenomenological content, so much so that the perceptual structure of trained smelling varies significantly from naive smelling. In a second step, I interpret the processes that determine such perceptual refinement in the context of neural decision-making processes, and I end with a positive outlook on how research in neuroscience can be used to benefit philosophical aesthetics

A New Perceptual Adverbialism

In this paper, I develop and defend a new adverbial theory of perception. I first present a semantics for direct-object perceptual reports that treats their object positions as supplying adverbial modifiers, and I show how this semantics definitively solves the many-property problem for adverbialism. My solution is distinctive in that it articulates adverbialism from within a well-established formal semantic framework and ties adverbialism to a plausible semantics for perceptual reports in English. I then go on to present adverbialism as a theory of the metaphysics of perception. The metaphysics I develop treats adverbial perception as a directed activity: it is an activity with success conditions. When perception is successful, the agent bears a relation to a concrete particular, but perception need not be successful; this allows perception to be fundamentally non-relational. The result is a novel formulation of adverbialism that eliminates the need for representational contents, but also treats successful and unsuccessful perceptual events as having a fundamental common factor

Plotinus: The First Philosopher of the Unconscious

Plotinus is sometimes referred to as “the first philosopher of the unconscious.” In his 1960 essay “Consciousness and Unconsciousness in Plotinus,” Hans Rudolph Schwyzer called Plotinus “the discoverer of the unconscious.” What exactly was Plotinus’ unconscious? In the Enneads, Plotinus asks about soul and intellect: “Why then…do we not consciously grasp them…? For not everything which is in the soul is immediately perceptible” (V.1.12.1–15).[i] In the De anima of Aristotle, “Mind does not think intermittently” (430a10–25).[ii]We cannot remember eternal mind in us, because passive mind is perishable. Is the productive or active intelligence in our mind that of which we are not conscious? Can productive intelligence be compared to unconscious thought? Plotinus suggests that we do not notice the activity of intellect because it is not engaged with objects of sense perception. The intellect must involve an activity prior to awareness. Awareness of intellectual activity only occurs when thinking is reflected as in a mirror, but knowledge in discursive reason, reason transitioning from one object to the next in a temporal sequence, is not self-knowledge. Only in the activity of intellect inaccessible to discursive reason is thinking as the equivalent of being. The intellectual act in mind is only apprehended when it is brought into the image-making power of mind through the logos or linguistic articulation; “we are always intellectually active but do not always apprehend our activity” (IV.3.30.1–17). If the Intellectual is the unconscious, then unconscious reason is superior to conscious reason. The inability of conscious reason to know itself in the illusion of self-consciousness is the premise of psychoanalysis in the twentieth century
