Kontrastnatur der Braunempfindung I

Projection with two projectors (a), (b). (a) throws a constant additional light and (b) projects a neutrally coloured slide with a black spot on an orange cardboard. The spot appears in this surrounding as a brown infield. When the light of (b) is dimmed in a neutral colour temperature so much that the luminosity of the surrounding approximates the luminosity of the infield, it appears orange, too. - Now the infield is shielded, the luminosity of (b) is varied strongly, as can be watched at the right bottom of the screen. The isolated infield keeps brown. - Repetition of the experiment.

Chromatischer Flächenkontrast nach Ragona Scina und Hering

The mirror experiment caused Osann (1837) to concede the occuring complementary colours the status of "objective complementary colours". In proof of their subjective nature first a fullscreen grey appearing infield detail. The picture is expanded to the surrounding and the infield shows contrast. Another zoom into the infield. - Demonstration of Hering's (1887) version of an experiment by Ragona Scina (1847). In the final shot the luminosity of the lying model object is varied.

Chromatischer Flächenkontrast nach H. Meyer und Koffka

According to Koffka 1915/1935 grey infields show no contrast when they lie divided in different coloured fields. Even a cover of flimsy paper - which according to Herm. Meyer 1855 has a contrast maximizing effect by blurring the edges and minimizing the luminosity gradient - does not change that. Contrast only results when the infields are arranged on the coloured fields in such a way that each has its own surrounding.

Scheinkonturen und Isoluminanz

Subjective contours (cognitive contours) are either interpreted as extraordinary cases of figure-ground-organisation or as effects of visual depth stimuli. They are no primary contrast effects, yet become clearly visible - like objective contours - only under the condition of a brightness contrast between figure and ground. Under the conditions of contrast and isoluminance the film shows: Heckhausen pattern, Kanisza triangles, subjective Necker's cube, Brunswik letters. (see Gregory 1972).

Rotierender Baukran

A rotating building crane (standing not too close to the spectator) is a modern pendant of Porterfield's windmill (film K 115). In both cases the depth clue of relative size is deleted by parallel projection. Regarding the crane the motion direction can be observed by means of remaining depth clues, especially of occlusion (model shots).

Bewegungsumkehr und Trapezgestalt II

Ames' window as a trapezium is the projection of a rectangle in linear perspective. Like the set of open spanners in film K 133 different flat objects can be composed as a trapezium. Whereas the row of open spanners can possibly be interpreted as one object this does not apply here. Nevertheless apparent motion reversal occurs. (Kalkofen 1987).

Lehmann-Liebmann-Effekt

Alfred Lehmann (Copenhagen, 1904) used isoluminance to test the irradiation theory of geometrical optical illusions; Susanne Liebmann (1927) demonstrated the disturbance of figure-ground differentiation in isoluminance. Variation of the figure-ground contrast with a lacy silhouette (by Lotte Reiniger), Münsterberg's "displaced chess piece", Zöllner's pattern, Frazer's spiral, Frazer's chessboard pattern.

Bewegungsumkehr und Textur

Wherease film K 151 demostrates how the rotating silhouette of an image with detailed inner contours constructed in central projection induces - as the image itself - apparent motion reversal, this film shows that an occlusive texture "isolatedly" induces similar phenomenons. Both templates are composed of telecentric images of a red/white ringed double cone. Template A (on the left) shows it equally oriented on both sides (red tip); template B shows alternative orientations (red tip, white tip). (Kalkofen 1982).

Simulation von Körperfarben

Surface colour and (mono- and polychrome) illumination or shadowing can substitute each other: a white module construction looks in the front projection of a slide of a similar construction made of coloured modules nearly like the latter. It is also demonstrated that polar projection is no question of "symbolic form". Finally a variation of Hering's spot-shade-experiment.

Wallach-Michotte-Bewegung

The objective motion of a circle excentrically fixed on a turntable can be divided into: the translational motion (a) around the centre of rotation and the rotation (b) around itself. In homogenous textures (b) is invisible (Wallach und Adams 1956). The exclusion of this component in a "stabilized" human body shape was, reverse, was not noticed by most of Michottes' (1962) test persons.

Rotierendes Amessches Fenster im Vergleich mit einem oszillierenden

Two Ames' windows side by side driven by one engine. During the time when the rotating - apparently oscillating - window describes a full circle the other one objectively rotates, the longer edge in the foreground. A second shooting angle shows this edge in the background; a higher camera position induces distortions in perspective and visualizes the motions.

Amessches Fenster vor dem Spiegel

Variation on Ames' window configuration (see also film K 59). Because the reflexion also points forward for reasons of perspective it rotates in the same direction as the original. This effect - indicating the core of Ames' oscillation - is to be distinguished form the floating inversion of the mirrored Necker cube (see film K 140).

Prüfung der Farbsehtüchtigkeit

Approximately 10 percent of the male population have colour vision that deviates from the "'normal' trichromats" (in the sense of Young-Helmholtz's Three Colour Theory") and exhibit congenital disturbances in the red-green region. - Their types and their heredity - Testing procedures Psuedo-isochromatic tables and alternatively pairs of colour samples are appropriate for screening tests. Nagel's anomalscope, which was conceived as a spectral colour mixing device, is available for the differential diagnosis of the disturbances in the red-green region and the exact determination of its degree of Expression. The Farnsworth-Munsel 100 Hue Test, a sorting procedure, allows the determination of particularly good colour differentiates within the group of the colour discriminators.

Variation der kinetischen Tiefe

A circular diaphragm shows an ellipse in the centre of homogenous periphery. With the eccentric shift of the rotating configuration the ellipse seems to move from the centre to the periphery of a (static) circle. Along with this movement characteristics of the Benussi-Musatti-effect appear.

Metzger-Zöller-Versuch

Metzger & Zöller demonstrated that an ensemble of even coloured objects appears as if they were illuminated in the same colour. An objectively monochromously illuminated ensemble of white objects can - reversely - appear as a group of objects of the same surface colour. Demonstrations of the differences between both situations.

Die Entwicklung des Denkens nach Jean Piaget - Konkrete Operationen

The development of thought, beginning at around early school age, is described using original experimental conditions as laid down by the Geneva psychologist Jean Piaget. The film shows how the ability to think operatively - with its essential characteristics of reversibility - makes possible the acquisition of stable classificatory and relational concepts as well as invariability (number, substance, quantity).

Handwerk des Lernens. Kamera-ethnographische Studien zur verborgenen Kreativität im Klassenzimmer

"Hand Skills of Learning" is an 11-part collection of short observations with the ethnographer's camera shot in the classroom of an elementary school (combined classes 4 - 6) in Berlin-Wedding. They show pupils' everyday practices concerning learning situations, educational rites and material arrangements in the classroom. Focussing on the pupils' hands the camera shows in these "manual skills" the fascinating micro interactions of the children who - although the class belongs to a so called "problem school" according to statistics - demonstate how to work hand in hand. Accompanying the videos the DVD offers text commentaries from ethnographic education research, practical education, and micro-ethnographic gesture studies.

Vorlesung über Methodik und Anwendung der ärztlichen Hypnose - II. Fraktionierte Hypnose, gestufte Aktivhypnose

The value, importance and use of hypnosis are explained in the framework of a film lecture. Together with the lecture a number of methods are demonstrated, first heterohypnosis, shown with a patient with anxiety syndrome. After an introductory talk and a few preliminary trials an initial hypnosis is demonstrated, induced by the fixation method. Other induction methods follow, like the fascination method, no longer in use, and the easily applied colour contrast method. Subsequently the course of a fractional hypnosis is shown in a subject with a basically sceptical attitude. Lastly a graduated active hypnosis, developed from autogenic training, is demonstrated as a modern form of hypnotherapy.

Psychopathologie und Motorik bei präseniler und seniler Demenz

On the basis of selected patients with senile dementia, Alzheimer's disease and Pick's atrophy, who were particularly suitable for film purposes, the auther examines the psychopathology and motor activity of presenile and senile diseases. In this regard the emphasis is placed on a subtile demonstration of the pathological deterioration of reflexes which are near the brain stem. In addition of this, particular attention is paid to the deterioration of speech.
