- Abstract
- Von Wahrnehmung und optischer Täuschung Wie nehmen wir die formenreiche, farbenfrohe, sich ständig verändernde Welt um uns wahr? Wie verarbeiten wir Informationen, die unsere Augen weitergeben? Was geht im menschlichen Gehirn vor, wenn wir Bewegung und Distanz begreifen? Wie trennen wir Illusion vor Realität - und warum ist menschliche Wahrnehmung so leicht zu täuschen? Im multimedialen Spiel entdecken Sie die faszinierendsten Phänomene des menschlichen Auges - und erleben seine Täuschbarkeit. Wissenschaftliche Erläuterungen, Videos, 3D-Animationen und über 300 Abbildungen entführen Sie in die Welt der visuellen Wahrnehmung. Besuchen Sie die Website der Illusionen. Holen Sie sich dort weitere Informationen, halten Sie sich über neueste Forschungsergebnisse auf dem laufenden, und tauschen Sie sich mit Fachleuten und Gleichgesinnten über Ihre eigenen Beobachtungen aus.

- Abstract
- Warum sind nachts alle Katzen grau und erscheinen dabei langsamer als bei Tag? Warum sehen Frauen anders als Männer? Warum ist der Himmel blau, die untergehende Sonne rot und manchmal - ganz selten - sogar grün? Warum brauchen wir zwei Augen? Wie wird der schiefe Turm von Pisa durch die richtige Farbwahl gerade? Wie kann man aus Farbe Bewegung und aus Bewegung Farbe machen? Antworten auf diese und viele andere Fragen führt dieses anschauliche Buch des Sehens vor Augen. In überraschenden Experimenten kann der Leser die Illusionen des Sehens und die erstaunlichen Seiten seiner eigenen Wahrnehmung selbst entdecken. Thomas Ditzinger, Bestsellerautor und theoretischer Physiker auf dem Gebiet komplexer Systeme, insbesondere der menschlichen Wahrnehmung, verrät Tricks und Tipps, wie man spielerisch und mit Spaß den neuesten Stand der Kognitionsforschung verstehen kann - auch was die Katzen betrifft: Denn es ist "nur" unsere Wahrnehmung, die die Katzen grau und langsam macht.

- Rez. in: Spektrum der Wissenschaft 2007, H.6, S.86 u.d.T.: "Ein Kompendium optischer Täuschungen: Die beeindruckende Materialfülle hilft über Schwächen der Darstellung hinweg." (R. Henkel): "Wenn wir morgens die Augen aufschlagen, umgibt uns unmittelbar unsere Welt-dreidimensional und farbig, stabil und allumfassend. Das geschieht mühelos und in einem Bruchteil einer Sekunde; und doch steckt dahinter eine hochkomplexe Wahrnehmungsleistung. Viele der dabei ablaufenden Verarbeitungsvorgänge sind weit davon entfernt, verstanden oder gar in nachvollziehbare Algorithmen abgebildet zu werden. Noch erstaunlicher als diese Diskrepanz zwischen der internen Komplexität und der erlebten Leichtigkeit des visuellen Erlebens ist es, wie sicher und stabil unsere Wahrnehmung trotzdem ist. Deshalb kommen wir in der Regel nicht auf die Idee, dass die Welt, so wie wir sie erleben, eine Konstruktion unseres Wahrnehmungsapparates ist. Thomas Ditzinger, Wissenschaftspublizist und Lektor beim Springer-Verlag in Heidelberg, gibt dem Leser eine Menge Material an die Hand, um Fehler dieser Konstruktion in Gestalt optischer Täuschungen zu erleben. Zahlreiche, manchmal frappierende Abbildungen führen unseren Wahrnehmungsapparat in die Irre und offenbaren damit ein schwaches Echo der Algorithmen, die im Hintergrund unsere visuelle Welt konstruieren. In sieben Kapiteln erörtert der Autor praktisch alle Aspekte der visuellen Wahrnehmung und die dazugehörigen Täuschungen von Raum, Fläche, Farbe, Bewegung und Entfernungssehen. Besonders faszinierend und verblüffend sind dabei die Abschnitte über mehrdeutige Wahrnehmungen und mehrere »autokinetische Bilder«, die ständig in Bewegung zu sein scheinen, obgleich sie ganz gewöhnlich auf Papier gedruckt sind. Als umfangreiches Bilderbuch der optischen Täuschungen ist das Werk eine wahre Fundgrube. Leider wird der gute erste Eindruck durch den Text deutlich getrübt. Man kann ja durchaus die Auseinandersetzung mit einem schwierigen wissenschaftlichen Thema als Reise darstellen; aber so, wie Ditzinger einen Busfahrer inklusive einer Schafherde mehrfach bemüht, um bestimmte Sachverhalte darzustellen, wirkt es reichlich gequält. Einige Passagen sind in etwa so verdaulich wie ein Physikbuch der 1970er Jahre. Typische Anfängerfehler haben die Schlusskorrektur unbeschadet überstanden; so nennt Ditzinger die farbempfindlichen Rezeptorzellen in der Netzhaut durchgängig »Zäpfchen« statt Zapfen. Ausgerechnet bei der ersten Abbildung, die eine Wahrnehmungsillusion zeigt, sind in der Beschreibung linkes und rechtes Auge verwechselt, sodass man die Täuschung nur erlebt, wenn man sich nicht an die Textbeschreibung hält. Auch das Fehlen der Rasterung in einer Abbildung eines Malteserkreuzes (S. 75) lässt den unbedarften Leser zunächst ratlos. Erst auf den folgenden Seiten ist das Kreuz dann so abgebildet, dass sich die beschriebene Illusion einstellt. In einigen weiteren Abbildungen, welche die Ideen der Gestalttheorie zum Inhalt haben, treibt die erwähnte Schafherde auch grafisch ihr Unwesen. Das sind wohl die »mit den Möglichkeiten der modernen Computergrafik ... neu gestalteten« Illusionen, die das Vorwort preist (das Werk ist eine überarbeitete Neuauflage eines vor einigen Jahren im Südwest-Verlag erschienenen Buchs). Da wären die bekannten klassischen Strichzeichnungen der Gestalttheoretiker prägnanter gewesen. Trotzdem ist Ditzingers Buch ein umfassendes Kompendium optischer Wahrnehmungsillusionen, die der Leser ansonsten nur über diverse Fachbücher verstreut finden würde. Da kann man angesichts der Materialfülle und des günstigen Preises die genannten Mängel wohl verschmerzen."

- Abstract
- Für uns alle ist Sehen selbstverständlich. Es benötigt wenig Anstrengung. Doch das Sehen von Bildern, Objekten, Tiefen und Bewegung ist ein komplexer Prozess. Erst im letzten Jahrhundert bzw. den letzten 2O Jahren konnten Wissenschafter Fortschritte im Verstehen von Sehvermögen und Wahrnehmung erzielen. Nehmen Sie sich kurz Zeit und beobachten Sie die Welt um sich. Wenn Sie etwa den Kopf neigen, neigt sich da nicht auch die WeIt? Wenn Sie ein Auge schließen, verringert das nicht Ihre Tiefenwahrnehmung? Beachten Sie, was mit Farbe passiert, wenn Sie unterschiedlich beleuchtet wird. Gehen Sie um ein Objekt herum: Die Form verändert sich, doch die Wahrnehmung bleibt die gleiche. "Dahinterkommen" ist ein wirklich wunderbarer Vorgang. Hauptsächlich spielt sich dieser jedoch im Gehirn ab und nicht in ihrem Auge! Lichtwellen gelangen in die Augen und dringen in die fotorezeptiven Zellen der Netzhaut ein. Die Bilder, die so auf Ihrer Netzhaut entstehen, seien diese nun zwei- oder dreidimensional, werden zu flachen Darstellungen auf einer gewölbten Oberfläche. Diese bewirken eine natürliche Doppeldeutigkeit der Bilder, die auf Ihre Netzhaut gelangen. Für jedes Bild auf der Netzhaut gibt es unendlich viele Möglichkeiten für dreidimensionale Situationen, die genau dieses gleiche Bild verursachen können. Ihr Auge jedoch entscheidet sich gewöhnlich für die korrekte Interpretation. Genau das tut Ihr Gehirn: Es interpretiert! Es gibt einige sehr starke Einschränkungen, wie es dazu kommt. Außerdem muss Ihr Sehapparat die "Antwort" schnell finden. Alles in allem funktionieren diese Einschränkungen. In der realen WeIt sehen Sie nicht viele Illusionen, da Ihr Sehsystem viele Möglichkeiten kennt, Mehrdeutigkeiten auszuschließen. Viele dieser Möglichkeiten stützen sich auf die Regelmäßigkeiten der Welt, in der wir leben. Visuelle Wahrnehmung ist auf jeden Fall ein Prozess, der Mehrdeutigkeiten ausschließt. Doch Fehler können auch hier passieren. Zu Zeiten kommt es zu Illusionen, wenn das Bild, das wir aufnehmen, nicht genügend Information besitzt, um Mehrdeutigkeit auszuschließen. Es fehlen etwa wichtige Hinweise, die in der realen WeIt existieren und Mehrdeutigkeit ausschließen könnten.
Andere Illusionen entstehen, wenn ein Bild eine Einschränkung verletzt, die auf einer Regelmäßigkeit unserer WeIt basiert. Andere Illusionen treten auf, weil zwei oder mehrere Einschränkungen miteinander in Konflikt stehen. Dies bedeutet, dass unser Auge das Geschehen auf mehrere Arten interpretieren kann. Obwohl das Bild auf Ihrer Netzhaut unverändert bleibt, sehen Sie nie eine Vermischung der beiden Wahrnehmungen, obwohl die beiden Interpretationen zwischen diesen hin- und hergerissen sind. So sind Illusionen sehr nützliche Werkzeuge für Wissenschafter. Sie können die verborgenen Einschränkungen des Sehsystems in einer Weise sichtbar machen, die das normale Sehvermögen nicht schafft. Viele Illusionen in diesem Buch werden Ihre Wahrnehmung wiederholt zum Narren halten, auch wenn Sie wissen, dass Sie hinters Licht geführt werden. Dies geschieht, weil es für Ihren Sehapparat wichtiger ist, seine Einschränkungen zu befolgen als sie zu verletzen, aus dem einfachen Grund, dass Sie auf etwas gestoßen sind, das ungewöhnlich, widersprüchlich oder paradox ist. Die Illusionen sind willkürlich in vier Galerien eingeteilt. Viele sind nicht allgemein bekannt, da sie ihren Ursprung in der Forschung haben. Es werden auch klassische Illusionen angeführt, wobei wir jedoch meist deren Effekt verstärkt bzw. gesteigert haben. Ich habe versucht, wissenschaftliche Erklärungen für die Illusionen zu liefern. Diese sind am Ende jeder Galerie angeführt. In vielen Fällen wissen wir jedoch heute noch keine Antwort. Dies trifft vor allem auf geometrische Illusionen wie etwa die Poggendorf-Illusion oder die Muller-Lyer-Illusion zu. Darum möchte ich betonen, dass die Erklärungen nicht auf allgemeine Gültigkeit plädieren, sondern durchaus skeptisch betrachtet werden sollen. Die Erforschung des Auges ist eines der aufregendsten Gebiete der Wissenschaft und das Studium von visuellen Illusionen bereitet große Freude. Ich hoffe, dass dieses Buch Jung und Alt überraschen und erfreuen wird und es auch zum Nachdenken über das wundersamste Mysterium dieses Universums anregt - dem menschlichen Gehirn.

- Abstract
- Der Begriff des Wissens geht davon aus, dass Tatbestände als 'wahr' und 'gerechtfertigt' angesehen werden. Die Gründe für solche Überzeugungen liegen in der Gewissheit der eigenen Wahrnehmung sowie in der Kommunikation dieser Wahrnehmungen. Beide Bedingungen befinden sich gegenwärtig im Umbruch: Unsere sinnliche Wahrnehmung wird durch Medien und Sensorsysteme gestützt, und die Verständigung über solcherart erzeugte Wahrnehmungen wird in wachsendem Maße telematisch kommuniziert. Die tendenziell globale Ausweitung der kollaborativen Erzeugung des Wissens durch computergestützte Netzwerke irritiert nicht nur die Vertrauensverhältnisse, die den Wissensprozessen zugrunde liegen, sondern auch die Struktur und Funktionen des Wissens selbst.

- Abstract
- Texas A&M University Libraries developed a Web-based training (WBT) application for LandView III, a federal depository CD-ROM publication using cross-browser dynamic HTML (DHTML) and other Web technologies. The interactive and self-paced tutorial demonstrates the major features of the CD-ROM and shows how to navigate the programs. The tutorial features dynamic HTML techniques, such as hiding, showing and moving layers; dragging objects; and windows-style drop-down menus. It also integrates interactive forms, common gateway interface (CGI), frames, and animated GIF images in the design of the WBT. After describing the design and implementation of the tutorial project, an evaluation of usage statistics and user feedback was conducted, as well as an assessment of its strengths and weaknesses, and a comparison of this tutorial with other common types of training methods. The present article describes an innovative approach for CD-ROM training using advanced Web technologies such as dynamic HTML, which can simulate and demonstrate the interactive use of the CD-ROM, as well as the actual search process of a database.

- Abstract
- Little research has compared youngsters' use of CD-ROM and the Internet for information-seeking purposes. Nevertheless, the area has recently been addressed within a largely qualitative project more generally devoted to young people's information universes. Home access to the Internet was seen to be more limited than that to CD-ROM, although the former was consulted to tackle needs of a greater number of types. The strategies employed to exploit each form of information resource were essentially similar. No attempts were reported to check the credibility of any information retrieved from electronic sources. The Internet was, however, used more frequently beyond the informants' own homes than was CD-ROM. There was also greater employment of the Internet by adults acting an the youngsters' behalf. As Internet use for school purposes rose in accordance with age, that of CD-ROM declined. When youngsters themselves compared the two resources as information-seeking tools, CD-ROM software was criticized for its lack of detailed material and the Internet for the problems in locating what was desired. Project findings have implications in a range of areas, including the marketing of CD-ROM packages, research and development and practices within schools.

- "Wissenschaft entlarvt Illusionen. Vor der zersetzenden Kraft ihrer schonungslosen Analyse scheint nichts sicher. Ob die Illusion von Erdscheibe und Himmelsgewölbe, das »Ich« und der »freie Wille«, ob die Linearität eines Zeitstroms oder auch nur die bunte Farbenpracht in der Welt »da draußen«. All dies gibt es nicht in einem objektiven Sinn, wie man naiv meinen könnte, sondern diese Ideen sind Konstrukte des Gehirns, die sich evolutionär bei der Meisterung des Lebens bewährt haben. Die Evolution setzt bekanntlich auf Nützlichkeit und nicht auf das bestmögliche Erkennen irgendeiner vorfindlichen Objektivität. Das »Ich« ist ein Selbstmodell des Gehirns, der »freie Wille« eine soziale Attribution, und die Farben sind vom Gehirn generierte Erlebnisqualitäten bloßer elektromagnetischer Strahlung in einer absolut farblosen Welt. Ob Fortschritte in der Kosmologie, Neurobiologie oder in den anderen naturwissenschaftlichen Unternehmungen: Paradoxerweise scheint mehr denn je Skepsis bei der erkenntnistheoretisch so bedeutsamen Frage angebracht, ob und in welcher Weise wir die Welt »da draußen« außerhalb unseres Bewusstseins überhaupt erkennen können."

- Abstract
- With the availability of full-text journals in CD-ROM and aggregator databases, libraries need to provide bibliographic and online access to these titles through the OPAC. The article reviews the experience of the King Fahd University of Petroleum & Minerals Library in providing analytical cataloging to the journal-title level of full-text CD-ROM databases, including Business Periodicals Ondisc (BPO), IEEE/ IEE Electronic Library (IEL), Applied Science & Technology Plus (AS&TP), and Readers' Guide Abstracts (RGA).
