AbstractInformation and communication technology (ICT) programs like Microsoft PowerPoint and Apple Keynote have become the norm for large university lecture classes, but their record in terms of student engagement and active learning is mixed at best. Here, the author presents the merits of a “populist” lecture style that takes full advantage of the variety of features available from the latest generation of ICT programs. Based on visual variety, audio and visual sound bites, and the incorporation of humor and pop-cultural references, this populist approach not only facilitates greater student attention and engagement with the class materials, but also offers unmatched opportunities for extending student learning beyond the confines of the large lecture hall.

Abstract Visual material perception is often studied with physically well-defined stimuli that lack ecological variety. Yet, even the visual variety found in our natural environment is limited when compared to artistic depiction. A similar object can be depicted in numerous different ways that all make visual sense. We studied the perception of translucency using 38 paintings of sea waves as experimental stimuli. It has previously been shown that translucency depends on the shape of the translucent object and on the light conditions. Both shape and light appear in many variations in depictions of seas. In the first experiment we explored the use of Thurstonian scaling and introduce the concept of Number of Distinguishable Levels (NDL). We found that the NDL ranged between 1.5 in a set with small waves to 4 in a set with large waves. While Experiment 1 took place in the lab, Experiment 2 was performed online and replicated the data from Experiment 1 qualitatively, although the NDL was lower in the online experiment. Furthermore, in this experiment we conducted Thurstonian scaling on a number of other attributes that possibly contribute to translucency perception, such as wavetip shading, surface reflections and realism. We found that many of these correlated significantly with translucency. In sum, this study advocates and demonstrates the use of uncontrolled stimuli, in our case paintings, to explore the wide variety of input the human visual system can process.

This work contains knowledge about a color theory that plays an important role in the process of planning the visual variety of clothing. The special attention is paid to the creation of the authors’ clothing models on the base of the color perception. The fractal structural model of perception of color is worked out. It allows taking into account character of functioning of component parts of this process. The consumers’ reactions to the color of a garment are taken into account. The consumers’ color preferences from the standpoint of not only the personality of the individual, but also the socio-psychological appearance are determined. Using the results of the current research, а designer can choose the color solution for single or serial production, as well as specify a certain color range, which can also be applied for outfits. In the last stage, a transition to the distribution of selected colors among the details of a garment is made. It takes into account the dimensions of the specific elements to obtain a harmonious combination of proportions of details.

In this section, we will consider archaeological textures as the archaeological element’s surface attributes having either tactile or visual variety, which characterize its appearance. The surfaces of archaeological objects, artifacts, and materials are not uniform but contain many variations; some of them are of visual or tactile nature. Such variations go beyond the peaks and valleys characterizing surface micro-topography, which is the obvious frame of reference for “textures” in usual speaking. Archaeological materials have variations in the local properties of their surfaces like albedo and color variations, uniformity, density, coarseness, roughness, regularity, linearity, directionality, frequency, phase, hardness, brightness, bumpiness, specularity, reflectivity, transparency, and so on. Texture is the name we give to the perception of these variations. What we are doing here is introducing a synonym for “perceptual variability” or “surface discontinuity.” It is a kind of perceptual information complementing shape information.
