Social determinants of health reflect the social factors and physical conditions of the environment in which people are born, live, learn, play, work, and age. Also known as social and physical determinants of health, they impact a wide range of health, functioning, and quality-of-life outcomes The question of whether or not figure-ground segmentation can occur without attention is unresolved. Early theorists assumed it can, but the evidence is scant and open to alternative interpretations. Recent research indicating that attention can influence figure-ground segmentation raises the question anew In two experiments, we employed the figure-ground stimuli adapted from Teki and colleagues' study (Teki et al., 2011) to analyze figure-ground segregation-related ERPs as a function of figure coherence and duration. Experiment 1 used behavioral methods a) to assess the optimal parameter ranges for figure coherence and duration to be used in. Rubin [55,56] first studied figure-ground segregation as an essential process to the existence of visual objects by studying general principles of figure-ground segregation assumed as the atoms of a more general grammar of phenomenology of vision. Rubin's main principles are surroundedness, size, orientation, contrast, closure, symmetry. Organization, Segregation and Object Recognition. stages are organized in a serial, hierarchical, manner: later stages are initiated after earlier stages are completed. Thus, in Marr's theory there is a clear sequence: depth-segregation first, access to object models (or representations) in memory later
The results were discussed in terms of determinants of figure-ground organization in auditory information processing. References Bregman, A S, Achim, A, 1973 Visual stream segregation Perception and Psychophysics 13 451 - 45 In the construction of emotion, the act of categorizing core affect performs a kind of figure-ground segregation (Barsalou, 1999, 2003), so that the experience of an emotion will stand out as a separate event from the ebb and flow of an ongoing core affect (the core affect is associated with the direction and urgency of initial behavioral. The goal of the present investigation is to extend this literature by examining the relation between independent sitting and figure-ground (FG) segregation in 6.5-month-old infants. Figure-ground (FG) assignment is vital to visual perception—it allows us to extract the meaningful objects (i.e., figures) from the less meaningful spaces between. Spatial variations in retinal motion signals carry key visual information about, for example, object motions, 3D object shape and figure-ground segregation (Lappin and Craft, 2000, Nakayama, 1985, Regan, 2000). In contrast, uniform motion fields are generally less informative and are often caused by our own eye and body motions

51 processing of visual information, such as figure-ground segregation. However, this 52 comes at the expense of global computations. Here we find that surround suppression 53 is not equally represented across mouse visual areas: primary visual cortex has 54 substantially more surround suppression than higher visual areas, and one higher are In an extreme example, Fahle (1993) reported figure-ground segregation in arrays of flickering dots based purely on flicker phase lags of as little as 6-7 ms between target and background dots, while Hancock, Walton, Mitchell, Plenderleith, and Phillips (2008) found that slightly longer asynchronies of 20-40 ms were effective for path. Neural sources underlying this bottom-up driven figure-ground segregation were localized to planum temporale, and the intraparietal sulcus, demonstrating that this area, outside the classic auditory system, is also involved in the early stages of auditory scene analysis
Third, as said above, symmetry can determine figure-ground segregation. In [ 32 ], figure-ground segregation was investigated in a patient who suffered from hemispatial neglect; following right-hemisphere damage, the patient was unable to deploy attention to the left half of the visual field, although he was not blind on that side Regan DM, Beverley KI.

[Google Scholar] Roitman JD, Shadlen MN The second non-specific property is the congruency -i.e., presence of a congruent or corresponding relationship between the shape and orientation of the contour and the spatial disposition of the inner features (Macchi Cassia et al., 2008).Faces are congruent because they display a greater number of features (the eyes) in the wider, upper portion of the face outline and only one. The general idea is that constructions are represented at different levels of schematicity that are connected by taxonomic links (also referred to as 'inheritance links'; Goldberg 1995: 73- 81).

Racism as a Core Determinant of Child Health. Racism is a core social determinant of health that is a driver of health inequities. 20 - 22 The World Health Organization defines social determinants of health as the conditions in which people are born, grow, live, work, and age. These determinants are influenced by economic, political, and social factors linked to health inequities. The perception of edges is thus a determinant of the extent of color assignment, it has been shown that pure-color form is lost at high frequencies (see Elsner, 1978) and that, in general, the luminance system is considered to have a higher spatial It is namely a figure-ground segregation task based on the idea that, if noise and signal. The general procedure was similar to that described earlier 23. Several months before the experiment, two probes, consisting of a 7 mm × 3 mm loop of hypodermic tubing, were placed side-by-side. Reconceptualizing figure-ground perception. Peterson, Mary A. Dept. of Psychology, University of Arizona, Tucson, USA. The processes producing shape perception are not yet understood. A fundamental assumption has been that figure-ground segregation is early stage in the process, but this assumption is mistaken
The relationship between color and form has been a long standing issue in visual science. A picture of functional segregation and topographic clustering emerges from anatomical and electrophysiological studies in animals, as well as by brain imaging studies in human. However, one of the many roles of chromatic information is to support form perception, and in some cases it can do so in a way. Neurons in the visual system integrate over a wide range of spatial scales. This diversity is thought to enable both local and global computations. To understand how spatial information is encoded across the mouse visual system, we use two-photon imaging to measure receptive fields (RFs) and size-tuning in primary visual cortex (V1) and three downstream higher visual areas (HVAs: LM. Freshness perception has received recent consideration in the field of consumer science mainly because of its hedonic dimension, which is assumed to influence consumers' preference and behavior. However, most studies have considered freshness as a multisensory attribute of food and beverage products without investigating the cognitive mechanisms at hand A 10-minute walk is also considered a reasonable distance for accessing public parks. This is the distance that The Trust for Public Land applies in their rating system developed to measure how well the 100 largest U.S. cities are meeting the need for parks. In 2017, San Francisco was the first city in the United States to reach the 10-minute walk to a park goal for all of its citizens

Although color plays a prominent part in our subjective experience of the visual world, the evolutionary advantage of color vision is still unclear [1-2], with most current answers pointing towards specialized uses, for example to detect ripe fruit amongst foliage [3-6]. We investigated whether color has a more general role in visual recognition by looking at the contribution of color to.

. In a variety of ways these investigations recognize the importance of dynamic segregation, of the determination of the part by the whole The basic principles of gestalt theory as related to visual r-.v 17 perception are: (1) figure-ground - every perception is a pattern related to a back-ground of other experiences. No figure is per-ceived in isolation. (2) segregation and differentiation - the pattern or stimuli form certain structures in perception owing to their special. The factors influencing the stream segregation of discrete tones and the perceived continuity of discrete tones as continuing through an interrupting masker are well understood as separate phenomena. Two experiments tested whether perceived continuity can influence the build-up of stream segregation by manipulating the perception of continuity during an induction sequence and measuring. Following the lead of the phenomenal data, Kohler proposed that there are macroscopic field processes in the brain, involving interactions which account for the effects of grouping and segregation and for the operation of the Prägnanz principle. Traditionally, cortical action was described in terms of separate excitations conducted along. Segregation of FF and FB pathways.

The laser scanner provides digitized images with accurate range data (±0.1 mm) at close ranges (from 0.6 m to 1.2 m ), with high spatial resolution (up to 307,200 points per acquisition). The device is also endowed with an RGB camera that acquires the actual image texture (640 × 480 pixels), aligned to the 3D scene Gestalt psychology, gestaltism or configurationism is a school of psychology that emerged in the early twentieth century in Austria and Germany as a theory of perception that was a rejection to the basic principles of Wilhelm Wundt's and Edward Titchener's elementalist and structuralist psychology.. As used in Gestalt psychology, the German word Gestalt (/ ɡ ə ˈ ʃ t æ l t,-ˈ ʃ t ɑː l. Multisensory integration, also known as multimodal integration, is the study of how information from the different sensory modalities (such as sight, sound, touch, smell, self-motion, and taste) may be integrated by the nervous system. A coherent representation of objects combining modalities enables animals to have meaningful perceptual experience Thus, it has been shown that small temporal offsets can induce figure-ground segregation (Leonards, Singer, & Fahle, 1996). As demonstrated in this study, a subset of elements in a flickered texture can be perceptually segregated if there is a temporal lag between figure and ground elements of more than 10 ms

A similar but opposite contingency between color and form has been demonstrated using the tilt-aftereffect: double adaptation to two gratings of different colors, one tilted to the left and one tilted to the right, will make a vertical test grating appear tilted to the direction opposite to that of the adaptation grating of the same color (Held and Shattuck, 1971) Social class, also called class, a group of people within a society who possess the same socioeconomic status. Besides being important in social theory, the concept of class as a collection of individuals sharing similar economic circumstances has been widely used in censuses and in studies of social mobility.

We analyzed the female participation i In fact, a long history of segregation, both formal and informal, limited African American access to parks and playgrounds until large numbers of white residents left the city in the 1950s and 1960s. It was only then that the city's black population spread out, gaining access to park facilities once considered off limits In view of these psychophysical findings, neurophysiological recordings of response latency differences between M and P neurons need to be subcategorized in the following manner (for a schematic illustration, see fig. 5 in Breitmeyer et al., Reference Breitmeyer, Kafaligonul, Öğmen, Mardon, Todd and Ziegler 2006)
Because border (contour) ownership is determined by depth order ( Nakayama, Shimojo, & Silverman, 1989 ), figure-ground segmentation necessarily involves depth segregation. In general, the figure tends to be seen in front, and the ground tends to be seen spreading behind the figure To quantify the performance of the encoding model in figure-ground segregation, we compute the mutual information between the absence (T = 0) or presence (T = 1) of the target odorant T and the glomerular activation pattern z. Noise is introduced due to the presence of background odorants of unknown sensitivities and activation efficacies Texture segregation is said to occur rapidly by preÂ attentive detection of differences in texton type or texton density. On a purely descriptive level there is general consensus on the elements (i.e. textons) that mediate texture segregation. However, there is no general agreement on the process by which segregation proceeds (cf Enns 1986) There is evidence that symmetry serves as a cue in classical figure-ground tasks [17,53-56], but local shape characteristics such as the path angle [21,46,47], and global characteristics such as convexity or familiarity seem to be more important determinants of performance in contour integration tasks Fig. 1.

Structural information theory is a coherent theory about the way the human visual system organises a raw visual stimulus into objects and object parts. To humans, a visual stimulus usually has one clear interpretation even though, in theory, any stimulus can be interpreted in numerous ways. To explain this, the theory focuses on the nature of. The results indicate that the boundary assignment to the compound items of the top-lit disks enhances the segregation of search items from the background, and that the search mechanism may access the relatively higher representation that includes figure-ground relations Until date, tonotopic separation and forward suppression in the auditory cortex have been considered as neural mechanisms of van Noorden's perceptual boundary , .Because of spatial separation on the tonotopic map, neural populations responsive to tones A and B become more distinct with increasing ΔF, thereby weakening the forward suppression in these populations All cortical and thalamic levels of sensory processing are subject to powerful top-down influences, the shaping of lower-level processes by more complex information. New findings on the diversity of top-down interactions show that cortical areas function as adaptive processors, being subject to attention, expectation, and perceptual task. Brain states are determined by the interactions between.

In cognitive psychology, reaction time (RT) is used to measure the amount of time that it takes an individual to process information (Luce).It is the duration of the interval between presentation of a stimulus (e.g., a word on a computer monitor) and the participant ' s response to the stimulus. RT is considered to be a dependent variable because it ' ' depends ' ' on. CONFIGR (CONtour FIgure GRound) is a computational model based on principles of biological vision that completes sparse and noisy image figures. Within an integrated vision/recognition system, CONFIGR posits an initial recognition stage which identifies figure pixels from spatially local input information The appeal and popularity of building blocks, i.e., simple and dissociable elements of behavior and experience, persists in psychological research. We begin our assessment of this research strategy with an historical review of structuralism (as espoused by E. B. Titchener) and behaviorism (espoused by J. B. Watson and B. F. Skinner), two movements that held the assumption in their. The distinct visual sensations of shape and texture have been studied separately in cortex; therefore, it remains unknown whether separate neuronal populations encode each of these properties or one population carries a joint encoding. We directly compared shape and texture selectivity of individual V4 neurons in awake macaques (1 male, 1 female) and found that V4 neurons lie along a continuum.
Childhood cancers can be classified into tumors in brain, cardiac, respiratory, digestive tract, and other organs. Brain tumors, accounting for about 30% of all childhood cancers , are difficult to treat.Although the survival rate has reached above 60%, the decline in quality of life, especially the cognitive deficits, still presents an important issue which receives increasing attention. Both figure-ground assignment and attention have been shown to enhance a target stimulus' spatial resolution and accelerate perceptual processing. In a texture-segmentation task in which performance peaks at mid-periphery and drops at both central and peripheral locations, attention improves performance at peripheral locations but hinders.

In this paper, we demonstrate that two characteristic properties of mammalian brains emerge when scaling-up modular, cortical structures. Firstly, the glia-to-neuron ratio is not constant across brains of different sizes: large mammalian brains have more glia per neuron than smaller brains. Our analyses suggest that if one assumes that glia number is proportional to wiring, a particular.
