Abstract:

Studies on brightness and lightness that employed luminance gradients (i.e., glare stimuli) have suggested that we can perceive luminosity even when the brightness target is darker than white. Although such studies had great impact on research in luminosity perception, whether the whiteness threshold in glare stimuli was lower or higher than the luminosity threshold remained unclear. This study indicated that it is higher than the luminosity threshold, confirming the existence of glowing gray. Moreover, we measured the luminance gradients’ effect on whiteness perception but found no significant effect. Discrepancy in the degree of gradients’ effect on perceived luminosity and perceived white suggests that different mechanisms underlie luminosity (brightness) perception and whiteness (lightness) perception.

Abstract:

The impression of self-luminosity in the glare effect was studied in two experiments. In experiment 1 the target (CS) was set to the highest luminance of the field and subjects were asked to adjust the luminance ramp of the inducers (R) against five backgrounds (B) to the point where they began to see CS as self-luminous. It was found that there is a linear relationship between background and luminance ramp. Another group of subjects carried out the same task in experiment 2, but this time CS and R were linked together so that CS would always have the same luminance as the highest luminance level of R, as adjustments were performed. It was found that: (i) adjustments were always lower than the highest luminance available; (ii) the linear relationship between background and luminance ramp was confirmed; (iii) observers reported a compelling impression of self-luminous grays. Data are discussed in relation to Bonato and Gilchrist's model for the perception of luminosity. The authors advance the hypothesis that luminance ramps are used at an early stage of encoding for the perception of luminosity.

Abstract:

The perception of luminosity is thought to depend upon the intensity of the stimulus: a surface begins to appear self-luminous when it emits or reflects a certain amount of light. This is known as the luminosity threshold. It is a common opinion among vision scientists that such a threshold is correlated to the intensity of a perceptually white surface, in the sense that only an area of the visual field with luminance higher than perceived surface-white will appear luminous. Here we show grey colours that appear luminous in virtue of surrounding luminance ramps. These ramps are intended to mimic halos seen around light sources in natural environments. The results of three experiments indicate that the phenomenon is in direct contradiction to the aforementioned assumptions and suggest the existence of separate perceptual pathways for self-luminosity perception and for surface-colour perception.

Abstract:

Observers were presented with target surfaces of varying luminance and asked to report whether they appeared luminous or opaque. In one experiment the targets were presented against three backgrounds, white, gray, and black. In another experiment the targets were presented within Mondrian patterns that were either brightly or dimly illuminated. The results indicate that, across a variety of conditions, a target begins to appear luminous when its luminance is about 1.7 times that of a surface that would appear white in the same illumination, whether or not a white surface is available in the visual field for comparison. Defined in this way the luminosity threshold exhibits the two main kinds of constancy characteristic of surface grays, constancy with respect to changes in the illumination level and constancy with respect to changes in the reflectance of the immediate background. This finding, while challenging a range of potential rules, places the problem of defining the conditions that produce luminosity squarely within the problem of lightness perception for opaque surfaces.

Abstract:

AbstractThe effect of unilateral depletion of retinal dopamine on goldfish visual behavior was studied using a behavioral reflex, the dorsal light reaction (DLR). Retinal dopamine was depleted by intraocular injections of 6–hydroxydopamine (6–OHDA) on two successive days. By 2 weeks postinjection, dopamine interplexiform cells (DA-IPC) were not detected using tyrosine-hydroxylase immunoreactivity (TH-IR). By 6 weeks postinjection, generation of DA-IPC was observed at the marginal zone and by 9 months postinjection, 2–3 rows of DA-IPC were present at the marginal zone. Neurites extended several hundred micrometers toward the central retina. By 2 weeks postinjection, all 6–OHDA lesioned fish tilted 7–15 deg toward the injected eye under uniform overhead illumination. The tilting did not occur under scotopic illumination and reappeared within 1 min of light adaptation. Quantitation of the DLR showed that 6–OHDA lesioned fish behaved as if light were 2.4 log units more intense to the injected eye. Partial recovery was observed by 9 months postinjection, paralleling the reappearance of DA-IPC at the marginal zone. Tilting also was induced by unilateral intraocular injection with Dl and D2 dopamine receptor antagonists, SCH 23390 and S(—)-sulpiride, respectively. Fish did not tilt if they were light adapted at the time of injection. Tilting was observed if the animals were dark-adapted for 3 h and left in the dark for 1 h postinjection. Fish tilted toward the drug-injected eye within 2 min of light adaptation and gradually returned to vertical within 2 h. The tilting response to S(—)-sulpiride was stronger (˜20 deg vs. ˜5 deg) and occurred at lower concentration (1 μM vs. 10 μM) compared to SCH 23390. We conclude that dopamine depletion mimics the dorsal light reaction by increasing the luminosity output of the eye and that dopamine is directly involved in photopic luminosity function.

Abstract:

L'amitié et l'affinité intellectuelle qui caractérisèrent les rapports de Hobbes avec Gassendi forment un tissu ténu dont il n'est point aisé de démêler la trame. Aux côtés de points de convergence clairement définis, telle la commune aversion envers le dualisme et l'innéisme cartésiens, et par-delà des divergences non moins nettes dans leurs orientations philosophiques particulières, le sens des parcours maintes fois parallèles doit encore être éclairé de façon circonstanciée. Le terrain privilégié sur lequel élever une confrontation étroite entre deux auteurs est sans doute la construction d'une psychologie profondément marquée par des prémisses empiriques et dont l'orientation vise à établir une relation très étroite entre les processus de la perception, du désir (appetitus) et de la volonté avec ce qui les détermine matériellement et mécaniquement. On peut même affirmer que les écrits de Gassendi rédigés au tout début des années 1640 définissent une série d'hypothèses innovatrices sur lesquelles s'inscrit une certaine convergence avec les élaborations de Hobbes à elles contemporaines. Sous ce profil, le groupe de textes remontant aux années 1640-41, et où le philosophe d'Aix s'interroge sur la nature des phénomènes lumineux, est emblématique. L'explication du comportement des corps lumineux en terme de systole et de diastole, l'interprétation de la propagation de la lumière s'inspirant de la pure actualité cinématique (en polémique ouverte et explicite envers les thèses de la Dioptrique de Descartes sur la luminosité comme simple inclinaison au mouvement), le vacuisme (qui est propre à Gassendi, servant justement à rendre compte des phénomènes d'expansion et de contraction des sources lumineuses et qui, à cette époque, n'était pas encore exclu par Hobbes), la représentation, enfin, tout à fait matérielle et mécanique des phénomènes d'irradiation, voilà autant d'aspects de la recherche de Gassendi qui peuvent facilement être confrontés aux écrits de Hobbes.

Abstract:

La détermination des paramètres physiques tels que la température effective, la gravité de surface, la luminosité, et le rayon d’une étoile nécessite une analyse adéquate de ses relevés spectroscopiques. Dans cet article, l’objectif est de déterminer ses paramètres physiques pour l’étoile HD149382 à partir de son spectre. Notre méthode indirecte consiste à déterminer la largeur à mi-hauteur des profils des raies He I λ471.362 nm, He I λ501.605 nm, et He I λ667.872 nm qui présentent un profil en cloche et qui résultent de la vie radiative au sein de l’étoile et de la durée de vie des particules suite aux collisions. Nous utilisons une courbe de Gauss (Gaussienne) pour la modélisation des raies de l’hélium. Cette modélisation à consister dans un premier temps à extraire les raies considérées et à les modéliser à partir du logiciel Matlab. Notre méthode est principalement basée sur la détermination de la température effective, le rayon, la gravité de surface et la luminosité de l’étoile HD149382 par effet Doppler grâce à la largeur à mi-hauteur du profil Gaussien de la raie d’absorption modélisée. Les résultats obtenus montrent que la température effective, la gravité de surface, la luminosité, et le rayon ont des valeurs comprises respectivement entre 33 427-40 051.7 K, 4.979-6.764 cm.s-2, 86.821-86.675 erg/K3/s et 3.34 Rʘ -10 Rʘ et que l’étoile HD149382 est une étoile naine de type sdB.

Full text

Abstract:

Relative luminance is fundamental to lightness perception, but can be used to predict specific lightness values only when coupled with an anchoring rule. Empirical results indicate that, in simple displays, lightness is anchored by the highest luminance (white) rather than by the average luminance (middle gray). This implies that increasing the luminance range of a stimulus causes grayness induction: the lower luminance values become darker gray while the highest luminance remains unchanged, as many so-called brightness induction experiments have shown. Yet sometimes increasing the luminance range of a stimulus causes luminosity induction: the highest luminance becomes increasingly self-luminous while the lowest luminances remain unchanged. Whether grayness induction or luminosity induction results from an increase in stimulus contrast depends on relative area. A few simple, yet hitherto unrecognised, rules that describe how anchoring by highest luminance combines with anchoring by largest area appear to be consistent with the many published reports on area and lightness/brightness. These findings add to the accumulating evidence that many phenomena previously attributed to contrast are much better understood in terms of anchoring.

Abstract:

This paper aims to study the sensory perception of Brazilian petit suisse cheese. Physicohemical (total sugar, total acidity, moisture, L*, a*, b* and soluble solids) physical (texture profile analysis- hardness, cohesiveness and gumminess) and sensory (color, appearance, taste, consistency and overall liking) analyses were performed. Three-way internal and external preference maps were used to evaluate the sensory profile of five different brands of strawberry flavor petit suisse (the only differences between them were the hydrocolloid bulking agents added) correlating with physical and physicochemical parameters. For this, the sisvar and sensoMaker software were used. According to the results, there is variation in the formulations of the petit suisse cheeses that are currently marketed in Brazil, with the exception of total acidity, moisture, and luminosity. Furtherore, Brazilian consumers prefer petit suisse cheese that has intermediate sweetness (7.67 °Bx to 11.67 °Bx) and reject those that are very sweet. In addition, products made with gelatin, pectin and locust bean and guar gums are more accepted.

Abstract:

The influence of photoperiod on the ability of Notothenia rossii Richardson, 1844 to detect prey was studied experimentally. In 12L/12D there was the highest number of individuals stimulated visually and chemically while in 24D chemical perception was the same as that observed in 12L/12D, the latter being lower than in 24L. The ultrastructure of chemo- and photo-sensory structures, involved in the detection of food, was studied. The photoreceptor cells of the retina are single and double cones, and rods. Taste buds were concentrated in the central part of upper and lower lips. Their shape is even, but the size is variable. The olfactory rosette has a sensory and a non-sensory epithelium, being rich in different mucosubstances. The conclusion was that in different photoperiods there is a difference in the response to visual and chemical stimulation for prey detection and that all sensory systems are more stimulated in periods of more luminosity, mainly when there is an alternation between light and dark periods. Sensory organs are complex when compared to some other Antarctic fish such as Gobionotothen gibberifrons Lönnberg, 1905 and Ophthalmolycus amberensis Tomo, Marshoff & Torno, 1977 but similar to those of N. coriiceps Rchardson, 1844.

Abstract:

The influence of tank color on the visual perception of fish larvae and the success of their cultivation depends on the characteristics of each species combined with environmental factors. In this study, we determined the effect of light and dark tank colors on the larviculture of pacamã (Lophiosilurusalexandri), a species with a benthonic habit, and curimatá-pioa (Prochilodus costatus), which swims actively in the water column. Larvae of pacamã and curimatá-pioa were cultivated for 10 days in 5-L tanks, at a density of 15 larvae L-1 and luminosity of 141.7 ± 8.95 lux, and fed Artemia nauplii. Four tank colors were used: green, light blue, brown, and black (with four replications). Survival, biomass and Fulton's condition factor for pacamã larvae were similar in the different colored tanks. However, the larvae in the green tanks showed lower weight than those cultivated in black and brown tanks, as well as shorter total length than that of larvae in the brown-colored tanks. These results are probably due to the association between tank color and benthonic habitat of the pacamã. For the curimatá-pioa, survival and biomass were similar for the different colors. The weight and Fulton's condition factor were higher for the larvae cultivated in green and blue tanks. This result could be associated with the adaptation of curimatá-pioa larvae to active swimming in the water column, searching for prey.

Abstract:

Objective. When exploring the scientific basis of reflexology techniques, elucidation of the surface and subsurface features of reflexology areas (RAs) is crucial. In this study, the subcutaneous features of RAs related to the lumbar vertebrae were evaluated by swept source-optical coherence tomography (SS-OCT) in subjects with and without low back pain (LBP).Methods. Volunteers without LBP (n=6(male : female = 1 : 1)) and subjects with LBP (n=15(male : female = 2 : 3)) were clinically examined in terms of skin colour (visual perception), localised tenderness (visual analogue scale) and structural as well as optical attributes as per SS-OCT. From each subject, 6 optical tomograms were recorded from equidistant transverse planes along the longitudinal axis of the RAs, and from each tomogram, 25 different spatial locations were considered for recording SS-OCT image attributes. The images were analysed with respect to the optical intensity distributions and thicknesses of different skin layers by using AxioVision Rel. 4.8.2 software. The SS-OCT images could be categorised into 4 pathological grades (i.e., 0, 1, 2, and 3) according to distinctness in the visible skin layers.Results. Three specific grades for abnormalities in SS-OCT images were identified considering gradual loss of distinctness and increase in luminosity of skin layers. Almost 90.05% subjects were of mixed type having predominance in certain grades.Conclusion. The skin SS-OCT system demonstrated a definite association of the surface features of healthy/unhealthy RAs with cutaneous features and the clinical status of the lumbar vertebrae.

Abstract:

Objective To develop a fine-grained phenomenological analysis of “pure awareness” experiences in meditators. Methods An online survey in five language versions (German, English, French, Spanish, Italian) collected data from January to March 2020. A total of 92 questionnaire items on a visual analogue scale were submitted to exploratory and confirmatory factor analysis. Results Out of 3627 submitted responses, 1403 were usable. Participants had a median age of 52 years (range: 17–88) and were evenly split between men and women (48.5% vs 50.0%). The majority of meditators practiced regularly (77.3%), were free of diagnosed mental disorders (92.4%) and did not regularly use any psychoactive substances (84.0%). Vipassana (43.9%) followed by Zen (34.9%) were the most frequently practiced meditation techniques. German (63.4%) and English (31.4%) were by far the most frequent questionnaire languages. A solution with 12 factors explaining 44% of the total variance was deemed optimal under joint conceptual and statistical considerations. The factors were named “Time, Effort and Desire,” “Peace, Bliss and Silence,” “Self-Knowledge, Autonomous Cognizance and Insight,” “Wakeful Presence,” “Pure Awareness in Dream and Sleep,” “Luminosity,” “Thoughts and Feelings,” “Emptiness and Non-egoic Self-awareness,” “Sensory Perception in Body and Space,” “Touching World and Self,” “Mental Agency,” and “Witness Consciousness.” This factor structure fit the data moderately well. Conclusions We have previously posited a phenomenological prototype for the experience of “pure awareness” as it occurs in the context of meditation practice. Here we offer a tentative 12-factor model to describe its phenomenal character in a fine-grained way. The current findings are in line with an earlier study extracting semantic constraints for a working definition of minimal phenomenal experience.

Social facilitation was measured and compared in conditions of constant light or during a light–darkness (LD) cycle, using ten Redwing Blackbirds (Agelaius phoeniceus), to determine the effects of social contacts between individuals in the absence of an LD cycle. Results showed that the LD cycle and social contacts had different effects depending on the type of behaviour involved. The LD cycle is more efficient than social stimulation in synchronizing activities, and social stimulation alone cannot synchronize feeding behaviour in individuals, although it can reduce the frequency of locomotory behaviours under conditions of alternating light and darkness. Each factor, LD cycle or social stimulation, can by itself have an important effect on the synchronization of grooming behaviours and the combination of the two factors further enhances synchrony. The role of social stimulation as a supplementary and complementary agent in synchronizing the activities in Redwing Blackbirds is discussed.

Abstract:

La tavelure du pommier (Venturia inaequalis) demeure la principale maladie à laquelle ont à faire face les pomiculteurs. La connaissance de l'état de l'inoculum primaire est essentielle pour mener une lutte efficace et économique contre cette maladie. Les relations entre le probit de la proportion d'asques vidés et les variables degrés-jours (base 0°C) et précipitations rapportées pour Frelighsburg, Québec, de 1981 à 1983 ont été comparées aux émissions d'ascospores enregistrées dans six autres localités réparties sur un axe NE-SO de 320 km pour les années 1982, 1985 et 1987. La variabilité des coefficients de régression a indiqué que ces variables ne sont pas des prédicteurs satisfaisants de l'éjection des ascospores pour cette période de temps. De nouvelles variables fonctionnelles basées sur la température, la précipitation, la luminosité et le temps ont été utilisées pour la construction d'un modèle de prédiction; celui-ci utilise la transformation angulaire de la proportion d'asques vidés et fait appel à la technique des moindres carrés pondérés en régression multiple ainsi qu'à une correction de toutes les variables dépendantes et indépendantes par le coefficient d'autocorrélation. L'équation obtenue a été validée sur l'aire géographique et les années incluses dans l'étude. L'intérêt principal de cette équation réside dans la possibilité de prédire la progression de la proportion d'ascospores éjectées ainsi que la fin de la période des infections primaires.

Abstract:

Sex discrimination in a newborn child is still present in Pakistan. It is despite relativewealth, rapid globalization, female education and socioeconomic development. Althoughmother’s education improves quality of childcare, but still it does not reduce discriminationagainst her children. The mental torture a female goes through in a life time for being femalestarts at the time of her birth and ends only with her life. These cultural bounded thinking hasovershadowed a woman’s own perception about a daughter. But some times to a family it doesnot make any difference that the child is a son or a daughter. Aims: The aim of the Researchis to discuss how mothers of a female child feel about having a daughter if they wanted tohave a son. Objectives: To explore what are the feelings of a mother upon having a daughter.To identify why they feel what they feel. To identify what are some of the reasons behindtheir thinking. To discuss how their experiences can be used in planning for interventions offuture this can help in a better understanding of our mothers and daughters requirements.Methodology: The methodology of current research is based on qualitative anthropologicalresearch method. Period: Dec 2014 to Oct 2015. Settings: The sampling is taken from differentsocioeconomic strata. It is divided into low, middle and upper socioeconomic groups. Everystratum is with a different point of view regarding the same question. Results: “In Pakistan 42percent of women accept violence as part of their fate; 33 percent feel too helpless to standup to it; 19 percent protested and 4 percent took action against it. Discussion: It is also foundthat the middle socioeconomic group is the most crushed group of all in Pakistan. This is thestrata who wanted to be modern like upper socioeconomic group but have lesser resourcesand opportunities. Females are educated equally like males in urban areas such as Lahore,Islamabad and Karachi. However, in rural areas, the education rate is substantially lower.Recommendation: For woman there must be a right to life, security and protection fromviolence which can be mental, physical, psychological and verbal. Government should ensureeffective, prompt and impartial investigations into alleged cases of crimes and other incidents,and ensure that particular attention is paid to the investigation of such crimes and incidents andthat those responsible for such acts are effectively brought to justice and, where appropriate,punished in order to avoid impunity.

Abstract:

For Gilles Deleuze's two essays ‘Causes and Reasons of Desert Islands’ and ‘Michel Tournier and the World Without Others’, the crucial question is what the perception is, what its fundamental conditions are. A desert island can be a place to experiment on this question. The types of perception are described in many critical works about the history of art and aesthetical reflections by artists. So I will try to retrace some types of perception especially linked to the ‘haptic’, the importance of which was rediscovered by Deleuze. The ‘haptic’ proposes a type of perception not linked to space, but to time in its aspects of genesis. And something incorporeal has to intervene in a very original stage of perception and of perception of time. Thus we will be able to capture some links between the fundamental aspects of perception and time in its ‘out of joint’ aspects (Aion).

Abstract:

How we perceive our body is shaped by sensory experiences with our surrounding environment, as witnessed by poor performance in tasks during which participants judge with their hands crossed the temporal order between two somatosensory stimuli, one applied on each hand. This suggests that somatosensory stimuli are not only processed according to a somatotopic representation but also a spatiotopic representation of the body. We investigated whether the perception of stimuli occurring in external space, such as visual stimuli, can also be influenced by the body posture and somatosensory stimuli. Participants performed temporal order judgements on pairs of visual stimuli, one in each side of space, with their hands uncrossed or crossed. In Experiment 1, participants’ hands were placed either near or far from the visual stimuli. In Experiment 2, the visual stimuli were preceded, either by 60 ms or 360 ms, by tactile stimuli applied on the hands placed near the visual stimuli. Manipulating the time interval was intended to activate either a somatotopic or a spatiotopic representation of somatic inputs. We did not obtain any evidence for an influence of body posture on visual temporal order judgment, suggesting that body perception is less relevant for processing extrabody stimuli than the reverse.
