often (but not always) figures. Object shape can assist in distinguishing figure from ground because figures tend to be convex. Movement also helps; the figure may be moving against a static environment. Color is also a cue because the background tends to continue as one color behind potentially multiple foreground figures, whose colors may vary. Edge assignment also helps; if the edge belongs to the figure, it defines the shape while the background exists behind the shape. However, it is sometimes difficult to distinguish between the two because the edge that would separate figure from ground is part of neither, equally defining both the figure and the background.

between the black and white regions is assigned. If the edges between the black and white regions are assigned inward, then the central white region is seen as a vase shape in front of a black background. No faces are perceived in this case. On the other hand, if the edges are assigned outward, then the two black profile faces are perceived on a white background, and no vase shape is perceived. The human visual system will settle on either of the interpretations of the Rubin vase and alternate between them, a phenomenon known as

143:. The word "gestalt" is a German word translated to English as "pattern" or "configuration." Gestalt concepts can also be referred to as "holism." Gestalt Psychologists were attempting to humanize what was considered a sterile approach. Gestalt psychology establishes that the whole of anything is greater than its parts. The concepts explored by Wertheimer, Köhler, and Koffka in the 20th century established the foundation for the modern study of perception.

In the typical sonic scenarios people encounter, auditory figure and ground signals often overlap in time as well as in frequency content. In these situations, auditory objects are established by integrating sound components both over time and frequency. A 2011 study suggests that the auditory system

Three- to four-month olds respond to differences in lightness rather than differences in form similarity. It is suggested that scaffolding (the development of new skills over time based on the building of other skills) is responsible for the development of perceptual organization. Environment plays a

The perceptual decision in which the brain decides which item is the figure and which are part of the ground in a visual scene can be based on many cues, all of which are of a probabilistic nature. For instance, size assists in distinguishing between the figure and the ground, as smaller regions are
239:
Subjective factors can also influence figure–ground perception. For instance, if a viewer has the intention to perceive one of the two regions as the figure, it will likely alter their ability to analyze the two regions objectively. In addition, if a viewer's gaze is fixated on a particular region,

The development of figure–ground perception begins the day the baby can focus on an object. The faces of caregivers, parents, and familiar objects are the first to be focused on and understood. As babies develop, they learn to distinguish the objects they desire from their surroundings. Sitting up,

Figure–ground perception precedes all other visual perceptual skills and is one of the first to develop in a young baby. The development of perceptual organization develops as early as infancy in human beings. In regards to nature versus nurture, concepts such as "lightness" and "proximity" may

possesses mechanisms that are sensitive to such cross-frequency and cross-time correlations. Results of this study demonstrated significant activations in the intraparietal sulcus (IPS) and the superior temporal sulcus related to bottom-up, stimulus-driven figure–ground decomposition.

The LOC (lateral occipital cortex) is highly important for figure–ground perception. This region of the visual cortex (located lateral to the fusiform gyrus and extending anteriorly and ventrally) has consistently shown stronger activation in response to objects versus non-objects."

Wertheimer described holism as the "fundamental formula" of
Gestalt psychology: "There are wholes, the behavior of which is not determined by that of their individual elements, but where the part-processes are themselves determined by the intrinsic nature of the whole."

Evidently, the process of distinguishing figure from ground (sometimes called figure–ground segmentation) is inherently probabilistic, and the best that the brain can do is to take all relevant cues into account to generate a probabilistic best-guess. In this light,

In crowded rooms or parties, a person is able to zero in on the conversation they are having with one person (figure) while drowning out the background noise (ground). This can also be referred to as the "cocktail party effect."

the viewer is more likely to view the fixated region as the figure. Although subjective factors can alter the probability of seeing the figure on one particular side of an edge, they tend not to overpower compositional cues.
