Das wichtigste Werkzeug des Menschen sind seine Hande. Obwohl dieses Sprichwort schon sehr alt ist, ist nur wenig daruber bekannt, wie und was der Mensch wahrnimmt, wenn er Objekte in die Hand nimmt und betastet. Wie wird die ertastete Form eines Objektes im Gehirn abgespeichert? Ist die haptische Reprasentation ahnlich zu der, der visuellen Wahrnehmung? Entsteht sogar eine multisensorische, und somit gemeinsame, Reprasentation? Diese fundamentalen Fragen bilden den Hintergrund der vorliegenden Dissertation. Die hier dargestellten Experimente zeigen, dass der Mensch sehr ahnliche perzeptuelle Raume generiert, wenn komplexe Formen eines parametrisch definierten Objektraumes visuell oder haptisch exploriert werden. Um dies zu zeigen, wurde zuerst ein dreidimensionaler Objektraum muschelahnlicher Objekte generiert, welche in drei Formparametern variieren. Versuchspersonen wurden in den visuellen Versuchen Fotos oder virtuelle Rekonstruktionen der Objekte gezeigt, wahrend in den haptischen Versuchen 3D Plastikmodelle der Objekte, generiert mit einem 3D Drucker, mit verbundenen Augen betastet wurden. In einer ersten Reihe von Experimenten bewerteten die Versuchspersonen die Ahnlichkeit zweier, nacheinander gezeigter, Objekte. Mit diesen Ahnlichkeitsbewertungen und mit Hilfe des Verfahrens der multidimensionalen Skalierung wurden die perzeptuellen Raume beider Modalitaten visualisiert. Uberraschenderweise konnten die Versuchspersonen die Topologie des Objektraumes korrekt nachbilden, unabhangig davon, ob sie die Objekte gesehen oder betastet hatten. Weiterhin zeigten die Ergebnisse, dass der visuelle und der haptische perzeptuelle Raum fast identisch waren. Als nachstes wurden drei Kategorisierungsexperimente durchgefuhrt. Obwohl Kategorisierung allein durch den Tastsinn eher eine ungewohnliche Aufgabe ist, konnte sie genauso gut gelost werden, wie wenn die Versuchspersonen die Objekte sehen konnten. Anschliessend wurden die perzeptuellen Raume beider Modalitaten mit den Ergebnissen der Kategorisierungsexperimente verglichen. Fur alle Kategorisierungsexperimente und fur beide Modalitaten war die wahrgenommene Ahnlichkeit zwischen Objekten einer Kategorie hoher, als die Ahnlichkeit zweier Objekte aus unterschiedlichen Kategorien. Das heisst, dass, sowohl visuell als auch haptisch, Objekte in einer Kategorie zusammengruppiert wurden, die als sehr ahnlich wahrgenommen wurden.Um zu untersuchen, inwieweit die auf den computergenerierten Objekten basierenden Ergebnisse auf naturliche Objekte ubertragbar sind, wurde eine Sammlung von Muscheln und Salzwasserschnecken erstellt. Mit diesen wurden, wie oben beschrieben, Ahnlichkeitsbewertungen durchgefuhrt und mittels multidimensionaler Skalierung die perzeptuellen Raume visualisiert. Wiederum waren der visuelle und der haptische perzeptuelle Raum fast identisch. Interessanterweise konnte man in beiden Raumen eine Gruppenbildung erkennen, weshalb auch hier drei Kategorisierungsexperimente durchgefuhrt wurden. Obwohl die Muscheln in einer Vielzahl an Objektmerkmalen variierten, z.B. Form, Farbe, Muster etc., konnten die Versuchspersonen diese Aufgabe ohne Muhe losen, auch wenn sie die Objekte nur betasten durften. Zusatzlich konnte die Gruppenbildung, die schon in den perzeptuellen Raumen erkennbar war, die Kategorisierungsergebnisse richtig vorhersagen.Zusammengenommen weisen diese Ergebnisse darauf hin, dass die visuelle und die haptische Reprasentation von Objekten sehr eng miteinander verknupft sein mussen. Zusatzlich liefern die Experimente Hinweise darauf, dass die gleichen Prozesse genutzt werden, wenn Ahnlichkeiten zwischen Objekten wahrgenommen werden, oder Objekte kategorisiert werden, egal ob die Objekte visuell oder haptisch exploriert werden.

"Marmodoro's monograph engages with Aristotle's views on a philosophically challenging question regarding perception, which has been central in the history of philosophy and is very much the focus of current debates in a number of philosophical and psychological disciplines: How do we become perceptually aware of objects in the world? Despite the significance of the question, the ways in which ancient philosophers have addressed it have only just begun to be be explored. There is a great wealth of insight on this question to be found in Aristotle, regarding our ability to perceive items in our environment, which he develops through his very demanding metaphysics, and Marmodo explores these insights in depth here. Aristotle's attempts at accounting for our awareness of complex perceptual content were highly original, drawing on and building on the metaphysics he has developed elsewhere in his works, but have not been adequately explored to date"--

This collection of research on object perception focuses on holistic and featural properties of objects, the mechanisms that produce such properties, how people choose one type of property over another, and how such choices are improved during the course of child development. The contributions consider alternative perceptual characterizations, the way in which such properties are represented in the mind, how particular properties are more useful in some kinds of tasks that humans perform, and how the developing child learns to cope with different properties in choosing among alternatives to optimize task performance. These papers were written by specialists for specialists in experimental, cognitive, and developmental psychology.

The present volumeis an annotated biblography of the vedik- Laksana, the esitence of which could be determined on the basic of printed editions, catalogues of manuscripts, and citations in other texts. the incentive for compiling this bibliography grew out of an awareness that hardly any relaible information exists concerning manuscripts of veda-laksana texts, although they are of great use critical studies of vedic texts. The goal of this work is to provide a comprehensive handbook of source materials on Veda-Laksna by identifying and distinguishing the texts in various manuscripts and printed editions according to their contents and actual title.

Does perception provide us with direct and unmediated access to the world around us? The so-called 'argument from illusion ' has traditionally been supposed to show otherwise: from the subject's point of view, perceptual illusions are often indistinguishable from veridical perceptions; hence, perceptual experience, as such, cannot provide us with knowledge of the world, but only with knowledge of how things appear to us. Disjunctive accounts of perceptual experience, first proposed by John McDowell and Paul Snowdon in the early 1980s and at the centre of current debates in the philosophy of perception, have been proposed to block this argument. According to the traditional view, a case of perception and a subjectively indistinguishable illusion or hallucination can exemplify what is fundamentally the same kind of mental state even though they differ in how they relate to the non-mental environment. In contrast, according to the disjunctive account, the concept of perceptual experience should be seen as essentially disjunctive, encompassing (at least) two distinct kinds of mental states, namely genuinely world-involving perceptions and mere appearances. This book presents seven recent essays on disjunctivism first published in two special issues of Philosophical Explorations: An International Journal for the Philosophy of Mind and Action.

Perception and its puzzles have given rise to philosophical reflection from antiquity to recent times: What do we perceive? How do we talk about what we perceive? What is the nature of our subjective experience? How can we talk about our subjective experience? In this book a distinguished group of philosophers addresses questions like these by drawing on historical and contemporary sources, illuminating the intersections between historical and contemporary philosophical discussion. They ask about the way things look; about how we can perceive a particular object (and no other); about self-perception; and about the nature and explanation of our phenomenal experience, and our talk about it. The book provides important new work in a central philosophical area.

An argument that there are perceptual mechanisms that retrieve information in cognitively and conceptually unmediated ways and that this sheds light on various philosophical issues. In Cognition and Perception, Athanassios Raftopoulos discusses the cognitive penetrability of perception and claims that there is a part of visual processes (which he calls “perception”) that results in representational states with nonconceptual content; that is, a part that retrieves information from visual scenes in conceptually unmediated, “bottom-up,” theory-neutral ways. Raftopoulos applies this insight to problems in philosophy of science, philosophy of mind, and epistemology, and examines how we access the external world through our perception as well as what we can know of that world. To show that there is a theory-neutral part of existence, Raftopoulos turns to cognitive science and argues that there is substantial scientific evidence. He then claims that perception induces representational states with nonconceptual content and examines the nature of the nonconceptual content. The nonconceptual information retrieved, he argues, does not allow the identification or recognition of an object but only its individuation as a discrete persistent object with certain spatiotemporal properties and other features. Object individuation, however, suffices to determine the referents of perceptual demonstratives. Raftopoulos defends his account in the context of current discussions on the issue of the theory-ladenness of perception (namely the Fodor-Churchland debate), and then discusses the repercussions of his thesis for problems in the philosophy of science. Finally, Raftopoulos claims that there is a minimal form of realism that is defensible. This minimal realism holds that objects, their spatiotemporal properties, and such features as shape, orientation, and motion are real, mind-independent properties in the world.
