0000051069 00000 n 0000037291 00000 n This effect has been attributed to differential allocation of visual attention (Hamada et al, 2002 Japanese Journal of Psychology 73 58 - 63, in Japanese). The task of the observer was to gaze at his/her reflected face within the mirror. 0000050939 00000 n 0000001781 00000 n All rights reserved. It was found that planar motion is the, In the Delboeuf illusion, a circle judged initially has a weaker effect of size induction than a circle judged subsequently (the judgment-order effect). Dissociative identity (compartmentalization of two or more identities) and depersonalization (detachment of bodily-self) were much higher in patients with AN than in HC. × You disliked this video. In this experiment, portrait artists were invited to draw strange-face illusions they perceived during a 10-minute session of eye-to-eye gazing while paired in dyads with naïve participants. Doing this tomorrow. Strange-face illusions are apparitional perceptions of deformed faces, unknown people and monstrous beings – that are produced when staring for a long time at one’s own face reflected in a mirror or when eye-to-eye staring at another person in a dyad, at low level room illumination. We also speculate that while target luminance information may be immune to masking resulting from perceived motion, it may be subject to masking due to lateral inhibition. 'border-locking mechanism' in the visual system. We found increasing dissociation after gazing in both conditions and a differentially stronger decrease of attractiveness ratings in the relevant gazing condition. Our search revealed a relative paucity of studies (n = 66) on environmental factors that ostensibly stimulate haunt-type experiences. A modified heart-beat tracking task measured interoceptive accuracy and awareness (confidence) before and after a validated dissociation induction procedure. 0000030961 00000 n At the end of a 10 min session of mirror gazing, the participant was asked to write what he or she saw in the mirror. occurred mandatorily once the outer circle was attended to, or whether it was necessary to direct attention specifically to the size of the area of the outer circle. Observers trisected the circumference of the outer circle thus attending to the outer circle in terms of its circumference, but ignoring its area. This exercise served as a much-needed update to an anthology of noteworthy overviews on ghosts, haunts, and poltergeists (Houran and Lange, 2001b). In a further experiment we find that luminance discriminations of the centre bar are related to the amount of abutting contour not to shape similarity. Discover (and save!) 0000035267 00000 n 18% encountered a parent's face with altered traits 28% saw an unknown face. We examined if the assumed effect of gazing rituals on attractiveness ratings exists and if it is associated with dissociation. motion-induced contour in the "dihedral edges" where the dihedral angles are 45, 90, or 135 deg. From those hypotheses, it would be possible to construct many formal models that permit universal computation in the mental world, through cellular automata. 0000026142 00000 n 0000048802 00000 n (f) fantastical and monstrous beings (48%), The disappearance or attenuation of face tr, explanation would predict that face traits should fade away and eventually, viewed self-reflections in dim light. Mirror-gazing and eye-to-eye-gazing produced anomalous experiences almost exclusively in the visual, bodily, and self-identity modalities, whereas psychomanteum experiences tended also to involve voices, smells, and bodily touches. To date however, the Mirror-Gazing test (MGT), an experimentally validated experiment to evaluate the propensity of strange face illusions in nonclinical and clinical adults, has yet to be investigated in an adolescent sample. Manipulations of the luminance of discrete regions in the mortar lines of the Café Wall, designed either to augment or cancel the effects of brightness induction in the production of these slanted line elements, are successful in enhancing or reducing, respectively, the wedge distortion of this visual illusion.

Strange-Face-in-the-Mirror Illusion. 0000026359 00000 n Limitations with regard to sample characteristics and experimental design are discussed. Another researcher also observed dissociative phenomena in individuals gazing at their own face in the mirror. 0000043887 00000 n Mental monism is gaining attention as a candidate solution to Chalmers’ Hard Problem on philosophical grounds, and it is therefore timely to examine possible formal models of consciousness within it. Here, I argue that the austere ontology of mental monism places certain constraints on possible models of consciousness, and propose a minimal set of hypotheses that a model of consciousness (within mental monism) should respect. According to some sources, the creature in the mirror is not a creature, but rather a result of a psychological phenomenon known as the strange face illusion. The lamp was placed on the floor behind the observer so that it was not visible either directly or in the mirror. admin. Strange-face illusions may be the 'projection' of the subject's unconscious contents into mirror image on the basis of somatic/motor mimicry and contagion. 0000003571 00000 n The results of the present experiment suggest an alternative explanation in which the operation of brightness induction within the mortar regions of the Café Wall produces a series of 'twisted cords' or slanted line elements akin to those of the Fraser or Zöllner figures. 18% saw an animal face such as that of a cat, pig, or These observations were made in a quiet room dimly lit by a 25 W incandescent light. To date … This illusion can be easily experienced and replicated as the details of the setting (in particular the room illumination) are not critical. We find that this relationship between shape similarity and reported visibility seems to be contingent on the degree of experienced apparent motion. Little attention has been given to modeling within a mental monist framework, deriving the structure and dynamics of the mental world from primitive mental constituents only. These interpretations suggest directions for future researches. This literature was diverse and often lacked methodological consistency and adherence to the prior suggestions.
