The results of earlier monocular experiments on the moon illusion have been either negative or confounded. To test the role of vestibular function, 24 subjects made forced-choice distance comparisons between stimuli mounted in translucent tubes. The stimulus tube for standard distance could be positioned in three viewing angles (45° up, horizontal, and 45° down). A comparison tube adjustable for distance was mounted horizontally. There was a greater perception of depth in the downward looking condition. The relatively weak effects are discussed in terms of a two-hypothesis explanation of the real-life moon illusion and the poor cues for depth perception in monocular viewing.

A study is reported of the binocular-oculomotor hypothesis of the moon illusion. In a dark hall, a pair of light points was presented straight ahead horizontally, and another pair was presented at the same distance but 50° upward. Twenty subjects compared the spacings of these two pairs. Half of the subjects viewed the stimuli first monocularly and then binocularly, and the other half viewed them in the reverse order. Eye position was also systematically varied, either level or elevated. A spacing illusion was consistently obtained during binocular viewing (with the upper spacing seen as smaller), but no illusion arose during monocular viewing unless it was preceded by binocular viewing. Furthermore, an enhancement of the illusion due to eye elevation was found only during binocular viewing. These findings replicate the report of Taylor and Boring (1942 American Journal of Psychology55 189–201), in which the moon was used as the stimulus, and support the binocular-oculomotor hypothesis as a partial explanation for the moon illusion.

The moon illusion is a visual deception when people perceive the angular diameter of the Moon/Sun near the horizon larger than that of the one higher in the sky. Some theories have been proposed to explain this illusion, but not any is generally accepted. Although several psychophysical experiments have been performed to study different aspects of the moon illusion, their results have sometimes contradicted each other. Artists frequently display(ed) the Moon/Sun in their paintings. If the Moon/Sun appears near the horizon, its painted disc is often exaggeratedly large. How great is the magnitude of moon illusion of painters? How different are the size enlargements of depicted lunar/solar discs? To answer these questions, we measured these magnitudes on 100 paintings collected from the period of 1534–2017. In psychophysical experiments, we also investigated the moon illusion of 10 test persons who had to estimate the size of the lunar/solar disc on 100 paintings and 100 landscape photographs from which the Moon/Sun was retouched. Compared to the lunar/solar disc calculated from reference distances estimated by test persons in paintings, painters overestimated the Moon's size on average Q  = 2.1 ± 1.6 times, while the Sun was painted Q  = 1.8 ± 1.2 times larger than the real one, where Q  =  r painted / r real is the ratio of the radii of painted ( r painted ) and real ( r real ) Moons/Suns. In landscape photos, test persons overestimated the Moon's size Q  = 1.6 ± 0.4 times and the Sun was assumed Q  = 1.7 ± 0.5 times larger than in reality, where Q  =  r test / r real is the ratio of the radius r test estimated by the test persons and the real radius r real of Moons/Suns. The majority of the magnitude of moon illusion Q  = 1.6, 1.7, 1.8, 2.1, 2.8, 2.9 measured by us are larger than the Q -values 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.8 obtained in previous psychophysical experiments due to methodological differences.

AbstractOur response to the commentators covers four general issues: (1) How useful is our proposed conceptualization of the real-life/laboratory controversy in terms of the contrast between the correspondence and storehouse metaphors? (2) What is the relationship between these two metaphors? (3) What are the unique implications of the correspondence metaphor for memory assessment and theory? (4) What are the nature and role of memory metaphors in memory research? We stress that the correspondence metaphor can be usefully exploited independent of the real-life/laboratory controversy, but that a variety of other metaphors, including the storehouse, should also be utilized in order to more fully capture the myriad facets and functions of memory in everyday life.

The article analyses the final lines of V. Soloviev’s work “The General Sense of Art,” correlating them with the art tendencies of the modern civilization. The author addresses Soloviev’s idea about the transforming role of art in relation to the reality, the real life. It is stated that, in the modern era, within the commercial mass culture domination, the entertaining function of art comes to the forefront. At the same time, an opposing tendency can be observed: a movement towards the all-encompassing unity, understanding of the universal, the priority of common values (the ideas of ecological ethics, common religion, non-violence). The author indicates that the dialectic negation of the negation law is manifested in the history of art, in the realization of its varied functions.

There is no doubt about the importance of shalat (prayer). As mentioned in the verses of al-Quran and some ahaadiits (prophet traditions), there are some importance of prayer, i.e. as the pillar of ad-diinul-Islam, the character of Muttaqiin (pious people), the direct order from Allah, the first-accounted ‘amal (action) in the hereafter, the standard of goodness, the guard from badness, the prove of gratitude, the border between believer and unbeliever, etc-etc. In addition, shalat has many important symbolic meanings which should be implemented in the real life in this world. Symbol can be defined as, by Victor Turner, "a thing regarded by general consent as naturally typifying or representing or recalling something by possession of analogous qualities or by association in fact or thought“ (Turner, 1967:19). Shalat is the symbol of life; Shalat has many values which could be implemented in the life. Symbols in shalat can be traced in its requirements, its movements, its recitations, and symbol of congregation (jama’ah). Symbol can be functioned by understanding and implementing it. Furthermore, shalat has four functions, i.e. communicative, educative, integrative, and safety function. In educative function, shalat can be used as a method of Islamic education. The function of shalat can be played by understanding shalat and implementing it. The main purpose of the paper is to explore symbolic meanings of shalat, in order that Muslims can understand and implement those meanings in the real life. In other words, Muslims are hopefully able not only “to do shalat (prayer)” but also “to establish it”. Both “ritual prayer” and “actual prayer” have to be implemented in the life. Allah Ta’alaa said, in the translation from al-Quran, “And keep up prayer (establish prayer) and pay the poor-rate and bow down with those who bow down (QS al-Baqarah 2:43). In the context of this ayat, “ritual prayer” is to establish prayer, and “actual prayer” is to pay the poor-rate.

Random-dot stereograms of an object standing out from a background always contain a monocular region at the side of the foreground object. This is equivalent to the monocularly occluded part of the background in the real-life viewing of one object in front of another. The role of these monocular regions in the stereoscopic process has not been investigated previously, although it is generally assumed that they are a source of difficulty in stereoscopic resolution because of the unmatchable texture within them. The basis of the present study was a prediction that the presence of texture within these regions would facilitate rather than retard stereoscopic processing. This prediction follows from a hypothesis that stereoscopic processing is initially located at disparity discontinuities. Unmatched regions are only found at such discontinuities, and could serve to locate them.

The paper presents the results of a study of the opinion of the fourth grade primary school students (N=60) from Sombor, Serbia, about the role of the textbook Nature and Society in the adoption of social contents. The aim of the study is to determine students? opinions about how the textbook assists them in adopting social contents and how this knowledge can be useful in the real life context, which can be a relevant starting point for improving the quality of textbooks. Qualitative methodology was used to analyse the obtained data. Focus group discussions pointed to problems about the presentation of social contents in the textbooks: extensive texts that must be memorised; the lack of explanations in the text; insufficient coherence of the text, which is the reason why the adoption of social contents require assistance in the interpretation of the text. Moreover, there is a problem in the relation between the text and visual displays; the examples given do not sound familiar to students, the text is not related to the real life context, which limits the usability of social knowledge adopted from the textbook. The students? answers refer to key standards of the textbook quality (the quality of the contents, the quality of the didactic design, the quality of the language used in the textbook), and indicate that the textbook that students use does not contribute to the process of learning complex social phenomena.
