Annotation:

Many psychological explanations have been advanced to explain left—right reversal in mirror images, but Gregory and Haig have each proposed a physical explanation for the reversal: the first is based upon the physical rotation used to present the surface of the object to the mirror, and the second on the classical optics of reflection. These physical explanations are considered together with an explanation based on object symmetry. The apparent reversal of directional coordinates (eg left and right) that occurs in the mirror images of most objects is distinguished from reversals achieved by ph

We tested between three levels of visuospatial adaptation (global map, parallel feature modules, and parallel sensorimotor transformations) by training subjects to reach and grasp virtual objects viewed through a left-right reversing prism, with either visual location or orientation feedback. Even though spatial information about the global left-right reversal was present in every training session, subjects trained with location feedback reached to the correct location but with the wrong (reversed) grasp orientation. Subjects trained with orientation feedback showed the opposite pattern. These

In a mirror, left and right are said to look reversed. Surprisingly, this very familiar phenomenon, mirror reversal, has still no agreed-upon account to date. This study compared a variety of accounts in the light of empirical data. In Experiment 1, 102 students judged whether the mirror image of a person or a character looked reversed or not in 15 settings and also judged the directional relation between its components. In Experiment 2, 52 students made the reversal judgements in 13 settings. It was found for the first time that a substantial proportion of people denied the left–right mirror

We analyze the existence of policy reversal, the phenomenon sometimes observed that a certain policy (say extreme left-wing) is implemented by the “unlikely” (right-wing) party. We formulate a Downsian signaling model where the incumbent government, through its choice of policy, reveals information both regarding own preferences and external circumstances that may call for a particular policy. We show that policy reversal may indeed exist as an equilibrium phenomenon. This is partly because the incumbent party has superior opportunities to reveal information, and partly because its reputation

The mirror puzzle related to the perception of mirror images as left–right reversed can be more fully understood by considering an extended problem that includes also the perception of mirror images that are not left–right reversed. 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 perceptio

Scolecodonts, the jaws of polychaetes, are the fossil evidence of the rich and diverse fauna that prospered in shelf seas. Among eunicid polychaetes, the largest jaws in the jaw apparatus occur in pairs. Normally these pairs are not exact mirror images of each other. Rarely, left and right jaws are found to be reversed, the jaw in the left position having the morphology of a mirror image of the normal right jaw and vice-versa. This type of morphological reversal (reversed handedness) is recorded with a frequency that varies from one reversed jaw in 430 to one in 5,838 of normal jaws. Reversed

Patent foramen ovale (PFO) is a congenital abnormality present in 25%–30% of healthy adults and rarely leads to any sequelae. 1 2 It is associated with a left-to-right shunt which usually does not lead to any haemodynamic compromise. Occasionally, the shunt can get reversed; that is, right-to-left shunt occurs due to worsening pulmonary hypertension and can lead to persistent hypoxia. It is rare for the shunt reversal to happen in the absence of pulmonary hypertension. Here, we present an exceedingly rare case in a 61-year-old man presenting with hypoxia, was found to have shunt reversal due t

Imagine a child′s toy arrow, sticking by its rubber sucker to a mirror′s reflective surface. We can call the direction in which such an arrow would point the finwards direction (forwards into the mirror); and we can call the opposite direction boutwards (backwards out). When we look at things in a mirror, their images are apparently just as far finwards of the mirror as the things themselves are boutwards of it. For example, if we look at the tail of our arrow and cast our glance finwards, we see first the tail, then the head, then the mirror, then the reflection of the head, and finally the r

The left-right body axis is defined relative to the dorsal-ventral and anterior-posterior body axes. Since left-right asymmetries are not randomly oriented with respect to dorsal-ventral and anterior-posterior spatial patterns, it is possible that a common mechanism determines all three axes in a coordinate manner. Two approaches were undertaken to determine whether alteration in dorsal-anterior development perturbs the left-right orientation of heart looping.

A mirror optically reverses the axis perpendicular to its surface, but apparent reversals (eg right—left) can be seen parallel to the surface. This poses a perceptual problem which Ittelson, Mowafy, and Magid resolved by concluding that an object appears to differ from its mirror image by an apparent reversal along its axis of greatest symmetry. Three papers—two included in this discussion (by Haig and by Morris), and an earlier one by Gregory—that disagree with this conclusion are examined, and arguments advanced in them are shown to be unconvincing.

The nearly neutral theory of molecular evolution predicts that small population size is essential for non-adaptive evolution. Evolution of whole-body left-right reversal in snails is generally a compelling example of non-adaptive speciation, because variants with reversed chirality would suffer from reduced mating opportunities within a population. Despite this reproductive disadvantage, sinistral snail species have repeatedly originated from dextral ancestors in terrestrial pulmonates. Here I show that snail speciation by reversal has been accelerated on oceanic islands. Analysing the global

The vertebrate body plan is overall symmetrical but left–right (LR) asymmetric in the shape and positioning of internal organs. Although several theories have been proposed, the biophysical mechanisms underlying LR asymmetry are still unclear, especially the role of cell chirality, the LR asymmetry at the cellular level, on organ asymmetry. Here with developing chicken embryos, we examine whether intrinsic cell chirality or handedness regulates cardiac C looping. Using a recently established biomaterial-based 3D culture platform, we demonstrate that chick cardiac cells before and during C loop

The human face at rest displays distinguishable asymmetries with some lateralization of emotion or expression. The asymmetrical nature of the resting face was examined by preparing hemifacial composites, left–left, right–right, along with normal facial orientation. The left side and right side composites were constructed by using the lateral half of one side of the face and its mirror-reversal. The left side facial composites were found to be more emotional than the right side or normal facial orientations of neutral expressions.

Abstract In his recent book, Capital and Ideology, French economist Thomas Piketty devotes the final chapter to the changing dimensions of political conflict in Western democracies. The goal of this article is to confront some of his findings with mainstream political science. Piketty’s arguments are confronted with the findings of scholars within political science. To begin the article, we establish two research questions in the introduction. We then delineate the gradual reversal of the educational cleavage and subsequent emergence of the multi-elite system according to Piketty. He demonstra

A microfossil study of two boreholes, Araromi and Gbekebo (Geological Survey of Nigeria borehole numbers 1131 and 1132) (Figure 1), revealed the occurrence of Buntonia beninensis Reyment (1960, 1963) in the late Paleocene interval. This species was found to have forms with normal overlap and hinge element and forms with a reversal of these morphological features. In the former, the left valve is larger than the right, which bears the projecting terminal hinge element, whereas, in the latter, the larger valve is the right valve with the smaller left valve bearing the projecting terminal hinge e

Abstract Background Resistant and uncontrolled hypertension prominently amplifies the risk of end-stage renal disease and fatal cardiovascular events. Therapeutic inertia, despite maximum tolerated anti-hypertensive medications, puts patients at high risk, thus non-pharmacologic therapies have been proposed. The ROX arteriovenous coupler (ROX, Medical Inc., San Clemente, CA, USA), initially developed for treatment of chronic obstructive pulmonary disease, exploits the biomechanical effects of diverting arterial blood into a low-resistance, high-compliance venous segment, thereby decreasing art

The extent to which pattern reversal evoked potential amplitudes are distributed symmetrically over the scalp was investigated as a function of stimulus spatial frequency. Nine right-handed male subjects viewed sinusoidal grating stimuli of 4.0 and 0.5 c/deg phase reversed every 900 msec. A visual half-field configuration enabled selective stimulation of the right- or left-hemisphere visual cortex. Evoked responses were recorded from the 2 cm above the inion (Oz) and at 7 and 13 cm lateral to Oz. Analyses of normalized evoked response amplitudes showed a significant asymmetry for the 4.0 c/deg

A study of hemi-field pattern reversal visual evoked potentials recorded in the interictal phase was carried out in 44 patients (22 with migraine with aura, 22 without aura) in order to determine whether migraine patients with or without aura and with headaches with strong unilateral predominance, either left or right, exhibit abnormalities after hemi-field stimulation. No differences of P100 latency were found between them and a group of 20 normal individuals, between patients suffering from migraine with aura and migraine without aura and between the affected and the non-affected side of the

Purpose: Our aim was to describe the radiographic features of lobar agenesis of the liver. Material and Methods: Six patients with lobar agenesis of the liver, 5 right- and one left-sided, are presented. CT was used to confirm diagnosis. Chest radiography, barium meals, and urograms were also analyzed. Results: In right-sided agenesis, the following were observed: a) hammock or U-shaped deformity of the stomach; b) colonic interposition of the diaphragm (Chilaiditi's syndrome); and c) reversal of the cranial orientation of the colonic hepatic flexure compared to the splenic flexure.

This study investigates the developmental progression of the acquisition of skills necessary for correct responses to various types of left-right identification tasks. The types of identification tasks which are considered in this study differ in terms of whether a midline body cross is required in the identification task and whether there is a reversal in the left-right orientation of the object being identified. A pairwise assessment of these various identification tasks is used to explore the nature of both “prerequisite” and “transference” relations that may exist among them.

AbstractWe report a patient in whom a cavopulmonary anastomosis had been constructed, along with repair of anomalous pulmonary venous drainage. Left-sided pulmonary venous obstruction led to redistribution of the flow to the right lung. The reversal of flow in the left pulmonary artery was accentuated by flow through collateral arteries feeding the left lung. Within 14 months, the collateral flow increased six-fold, resulting in a doubling of the cardiac output.

A 61-year-old woman was referred to our institution for evaluation of severe nonischemic dilated cardiomyopathy and left bundle branch block (LBBB). After permanent His bundle pacing, the LBBB was immediately corrected; however, the right bundle branch was injured during the procedure. Subsequent recovery of the right bundle branch block and normalization of heart function were observed during follow-up. This case indicates that LBBB might result in the development of nonischemic cardiomyopathy and emphasizes the necessity of a temporary pacemaker during His bundle pacing for patients with LBB
