The purpose of the present study is to clarify the physical aspect of this extended problem logically and parsimoniously. The separate use of intrinsic frames of reference (IFR) for the object and its mirror image leads to the perception of the left–right reversal as suggested by the latest authors on the mirror puzzle, and the application of a common frame of reference (CFR) to both the object and its mirror image causes the reversal of the axis normal to the mirror, resulting in left–right nonreversal in most practical cases. Only when the left–right axis of a CFR coincides with the axis normal to the mirror, left–right reversal is perceived of the mirror image under the application of the CFR.

The purpose of the present study is to clarify the physical aspect of this extended problem logically and parsimoniously. Separate use of the intrinsic frame of reference that belongs to the object and one that belongs to its mirror image always leads to the perception of left–right reversal when the object has left–right asymmetry; on the other hand, the perception of left–right nonreversal is always due to the application of a common frame of reference to the object and its mirror image.

This article introduces two groups of museum staff who have evaluated the usability of mobile guidance systems in Japanese museums. One group is the research team who used the PDA system in The National Science Museum, Tokyo, and the other is the user-support staff of Kitakyushu Museum of Natural History and Human History. In the former research we asked the members of the group to give their comments about the usability of the PDA, and in the latter research we conducted open-ended interviews individually with the museum staff. As a result, we obtained various opinions from each group. They often differed in their opinions from those of the general public.

The main concern for him was the nativism-empiricism controversy of space, which he intended to settle by means of empirical analysis. Current visual transposition experiments are conducted with rather different aims. Recent research has focused on a variety of basic problems in perception, such as intersensory interaction, sensorimotor integration, spatial frames of reference, and position constancy. Rock (1966) and Welch (1986) were more concerned with "non-change of polarity" transpositions, such as displacement, magnification, or tilting, than with "change of polarity" transpositions, notably up-down or left-right reversal. Welch (1986) wrote, "in attempting to answer Stratton's original question it is unnecessary to transpose the visual field. Instead, a sufficient test of the issue should be possible by merely tilting" (p. 17). As mentioned above, however, researchers today would not generally seek to answer Stratton's original question, but would pursue the important and unique advantages of "change of polarity" transpositions for understanding spatial perception beyond the scope of "non-change of polarity" transpositions. Under the former, perceptual adaptation may be expected to be in an all-or-none

Horizontal eye movements of 8 males and 8 females during reflection were recorded by means of electro-oculography. All the subjects showed fewer lateral eye movements in eyes-closed condition than in eyes-open condition, and neither the consistency of direction nor the effect of question types was replicated. These facts cannot be explained by the hemispheric activation hypothesis.
