    Effects of Changes of Observer Vantage Points on the Perception of Spatial Structure in Perspective Images: Basic Geometric Analysis.Dejan Todorović - 2022 - Axiomathes 32 (5):765-791.
    Every linear perspective image has a center of the perspective construction. Only when observed from that location does a 2D image provide the same stimulus as the original 3D scene. Geometric analyses indicate that observing the image from other vantage points should affect the perceived spatial structure of the scene conveyed by the image, involving transformations such as shear, compression, and dilation. Based on previous research, this paper presents a detailed account of these transformations. The analyses are presented in a (...)

    From Cubes to Ribbons: Transformation of an Illusion.Dejan Todorović & Jocelyn Penny Small - 2018 - Gestalt Theory 40 (2):119-130.
    Summary In Part 1 Small describes her discovery that an array of depicted cubes produces another and completely different illusion from that of a single cube. When a group of such cubes are viewed at an angle, they turn into rectangular boxes, and as the angle gets more severe, they become narrow ribbons. The illusion works only in one direction. In Part 2, Todorović manipulates the image to demonstrate various transformations and offers an explanation of how and why they work (...)

  4. Wittgenstein's 'impossible' colors: Transparent whites and luminous grays.Dejan Todorovic - 2017 - Belgrade Philosophical Annual 30:213-223.
    In the book Remarks on Colors, Wittgenstein has claimed that transparent white objects do not and cannot exist, and that they cannot even be imagined. He had also claimed that luminous gray does not exist and cannot even be conceived. However, his arguments which aim to identify contradictory features of hypothetical transparent white media rely on incorrect assumptions about their properties and effects. Furthermore, some real objects and atmospheric phenomena can have features of transparent white media. As concrete examples of (...)

    Color realism and color illusions.Dejan Todorovic - 2003 - Behavioral and Brain Sciences 26 (1):49-50.
    As demonstrated by several example displays, color illusions challenge color realism, because they involve a one-to-many reflectance-to-color mapping. Solving this problem by differentiating between veridical and illusory colors corresponding to the same reflectance is hampered because of the lack of an appropriate criterion. However, the difference between veridical and illusory color perception can still be maintained.

    Measurement theory is a poor model of the relation of kinematic geometry and perception of motion.Dejan Todorovič - 2001 - Behavioral and Brain Sciences 24 (4):705-706.
    The Kubovy-Epstein proposal for the formalization of the relation between kinematic geometry and perception of motion has formal problems in itself. Motion phenomena are inadequately captured by the relational structures and the notion of isomorphism taken over from measurement theory. [Kubovy & Epstein].

    In defense of neuro-perceptual isomorphism.Dejan Todorović - 1998 - Behavioral and Brain Sciences 21 (6):774-775.
    It is argued that the notion of bridge locus is compatible with distributed representation and brain interconnectivity. Isomorphism is not a dogmatic condition on explanatory adequacy but a refutable hypothesis, superior to Dennett's proposed alternatives. The assumption of type-type neuro-perceptual correspondences is more parsimonious than multiple realizability.

    Is kinematic geometry an internalized regularity?Dejan Todorovič - 2001 - Behavioral and Brain Sciences 24 (4):641-651.
    A general framework for the explanation of perceptual phenomena as internalizations of external regularities was developed by R. N. Shepard. A particular example of this framework is his account of perceived curvilinear apparent motions. This paper contains a brief summary of the relevant psychophysical data, some basic kinematical considerations and examples, and several criticisms of Shepard's account. The criticisms concern the feasibility of internalization of critical motion types, the roles of simplicity and uniqueness, the contrast between classical physics and kinematic (...)

  11. Amodal Completion of Color.Dejan Todorović - 2022 - Gestalt Theory 44 (1-2):117-146.
    Summary Amodal completion involves the impression of existence and properties of visually occluded parts of objects. One aspect of this phenomenon that has been somewhat neglected is the amodal completion of color, which involves the impression that amodally completed surfaces have a particular color. In this paper, this aspect is investigated by constructing a large number of displays with identical target figures embedded in systematically varying contexts, to find out which contexts are conducive for amodal completion of color and which (...)
