Sorted by: Results 1 - 10 of 598. The reason is that surfaces are where a lot of the action is. Child: Care, Health and Development, 26, . This means we acquire direct perception if there is an affordance and enough information in the environment is present to specify the affordance. Gibson, James J. Sensory information is received from the environment, converted to electrical impulses and processed by specific brain areas. According to Gibson [8, 9] affordance refers to the perceived possibility of actions that a person may take in an environment. According to Gibson, perception is a direct process that doesn't require past knowledge or inference. Some actions are common to most people, like seeing a refrigerator door and deciding to open it because of hunger. Gibson believed that all the information in perception is provided in the environment, it is direct and has no interferences with upper brain processing. In HCI, to afford means to invite or to suggest. That is why it is used as the definition for visual clues in a persons environment in this theory. In 1991 William Gaver created a framework for separating affordances from the perceptual information available. Meaning the user assumes an action can be made outside of the actions that are being presented to them. Nevertheless, studies investigating affordances in respect of teaching, learning or using languages are still somewhat rare and tend to treat isolated aspects of multilingualism. Moreover, perception is often instantaneous, supporting the direct theory of perception. understanding of affordances as realconstitutive of the phenomenal Gibson further develops the concept of affordances using a series of James J. Gibson Status as a Theory of Learning Affordance Theory aligns with Eco-Complexity Discourses, but it is not a theory of learning. The Theory of Affordances By James J. Gibson Book The Ecological Approach to Visual Perception Edition 1st Edition First Published 2014 Imprint Psychology Press Pages 17 eBook ISBN 9781315740218 Previous Chapter Next Chapter You do not have access to this content currently. Gibson believed that perception is direct and meaningful. Sensory data, like visual information, is complex and can provide us with information like depth, motion or distance. Further expanding upon his work, in 1979 Gibson wrote an in depth analysis on affordances in his book The Ecological Approach to Visual Perception. Gibson suggests that what people see will lead to a decision that they make. Sophistic Ways.". Affordances are species-specific; they are functionally generic, in this This is why observers perceive edibility differently. Prior to Gibson's work, psychologists had the idea that the real world was never actually seen. Humans evolved to make accurate judgements based solely on the sensory information we receive. The fact that perception guides our actions can be used to make people slow down when driving. Information only travels in one direction. For example, infants intuitively show fear of rights when approaching a cliff, even if they haven't experienced falling off of a cliff before. In contrast, the top-down theory of perception (constructivist approach) argues that our past experiences and expectations heavily influence perception. Surfaces reflect light, for instance. The idea of affordances is that we receive information about how we can act about it by looking at objects. Gibson: Gibson's theory is known as an 'ecological' theory: with background, horizons, other objects, etc. Summary: Gibsons The Theory of Affordances. Often used to denote possibilities offered by technologies, the concept has been imported into CALL from cognate domains, such as human-computer Interaction (HCI). Motion parallax is a monocular depth cue experienced during movement. It was not until the late 80s when researcher Don Norman coined the phrase perceived affordances and began applying these principles to the field of human-computer interaction (HCI). Especially in busy environments, we can focus on more important stimuli while ignoring others selectively. Earn points, unlock badges and level up while studying. In his later works, including The Ecological Approach . It can create confusion, however, because being able to afford something tends to take on monetary terminology. What do detached objects afford? It has received 357 citation(s) till now. It could be an explanation as to why certain people tend to be extroverts and others tend to be introverts. Sign up to highlight and take notes. The properties of an object that allow it to function. In the final section of the essay, Gibson distinguishes between perceiving What is the difference between top-down and bottom-up theories of perception? The animals that developed the ability to quickly process the information from the environment were, therefore, more likely to survive. When we are moving objects that are near appear to move faster in relation to us, while objects that are further away appear to move slower. Bottom-up processing is data-driven and fully based on sensory information. mistaken for sand, that a pitfall can be mistaken for solid ground, that poison experience of hearing), which involves interpretation and inference according to constructivists. How did Gibson first develop his theory on location perception? After all, Gibson established the term affordance with a very specific use in mind in conjunction with his theory of direct perception. distorted images or sounds) don't make any sense to us.

Perception and affordances The origins of affordance theory and adaptation for HCI design. Gibson is influenced by the theory of valences developed by the Gestalt psychologists, for whom the relationship between the above listed things from the environment is subject to the needs of the observer. experimental edge of the thing-in-use? The concept of affordances originates from ecological psychology; it was proposed by James Gibson (1977, 1979) to denote action possibilities provided to the actor by the environment. of the users don't pass the Gibson's Theory of Direct Perception quiz! An example of a natural illusion is the waterfall illusion. Top-down processing, StudySmarter Originals, Alicja Blaszkiewicz. Physical clues of an object act as indicators of a desired action. For instance, the edibility of an apple is perceived in relation to observers individual mouth, teeth, and digestive system (79). The Affording of Concealment (73): from ecological optics, In the article titled The Theory of Affordances, Gibson writes: "An import ant fact about the affordances of the environment is that they are in a sense objective, real, and physical, unlike values and meanings, which are often supposed to be subjective, phenomenal, and mental. Proposed by James J. Gibson, affordance theory is an examination of how each person visually perceives their environment. question-guided subsections: What do substances afford? Visual perception fails because of an absence of stimulation (i.e. James Gibson (1966) argues that perception is direct, and not subject to hypotheses testing as Gregory proposed. An affordance is what a user can do with an object based on the user's capabilities. Perception occurs instantaneously. He received his Ph.D. from Princeton University and his first major work was The Perception of the Visual World (1950) in which he rejected behaviorism for a view based on his own experimental work.. When we are moving, objects near appear to move faster in relation to us, while objects far away appear to move slower. Gibson proposed that we can perceive affordances (opportunities to act) directly from sensory information. Papers / Affordances and the Body: An Intentional Analysis of Gibson's Ecological Approach to Visual Perception; (74): manipulation and tool-use Because those visual cues are personal, others are hesitant to act upon using them because they are not theirs, which creates a level of social isolation that may be desired. Gibson's book The Ecological Approach to Visual Perception is most concerned with how animals perceive their environment, which Gibson argues is through the perception of affordances in the environment. animal. This article sets out the eWits model of the pedagogical affordances of ICTs. How is the fact that perception guides action applied to make people drive slower? The information travels only in one direction and past knowledge is not required for making accurate judgements about the environment. You can experience motion parallax when looking outside of the window of a moving car or a train. articulates the nuances in its application to ecological psychology. Rating: (not yet rated) 0 with reviews - Be the first. is only one environment, although it contains many observers with limitless By gradually putting lines painted on roads closer and closer together, drivers can be made to think that they are speeding, which can cause them to slow down. It applies elements of the notion of affordances to three documented anecdotes of Godly Play storytellers to show particular action possibilities enhance opportunities for spiritual development and wellbeing. Is direct perception the product of nature or nurture? This is a common view of both of the theories of perception. affordance is not wholly dependent on the observers perspective nor on the These affordances are then an essential component of human socialization. Sensory data can provide accurate motion and depth information, as exemplified by motion parallax. And we also design for usability by presenting information that specifies those affordances. Gibson's and Gregory's theories of perception both suggest that eye-retina is important for perception. Perception doesn't require the use of past knowledge or the interpretation of sensory data. This article is published in Journal for The Theory of Social Behaviour.The article was published on 1989-03-01. Affordances are those perceived aspects of the environment that suggest Free and expert-verified textbook solutions. Stop procrastinating with our smart planner features. They also take root in a all playing a part. The both believe that without eye-retina, a person will not be able to see. They thought that the eyes only provide a faulty input, that is a shadow of reality, rather than a. Motion parallax is a way for us to directly gain information about the distance of objects around us based on the sensory information we receive. This process is direct, the information travels only in one direction, and past experiences or interpretations are not required to make accurate judgments about the environment. Summary Jonathan Hey: The DIKW chain & James Gibson: The Theory of . R.E. Affordance is defined as what the environment offers the individual and what it provides or furnishes, either good or ill . Its 100% free. The constructivist view of perception requires additional interpretation of information, which should take longer than direct perception. Top-down processing is bidirectional. THE AFFORDANCES OF THE HOME . His theory is sometimes known as the 'Ecological Theory' because of the claim that perception can be explained solely in terms of the environment. If researchers are intentionally shifting from Gibson's definition of the affordance concept, it can be useful to approach the term in the way done by Norman (1999) and Bub et al. An example of direct perception is the ability to perceive the relative distance of an object based on motion parallax. He developed his theory whilst preparing films for pilots, which lead to him developing optic flow patterns. According to Gibson ( 1979 ), an affordance is a resource that the environment offers any animal that has the capabilities to perceive and use it. Gibson started his career at Smith College where he taught psychology. 9 The Theory of Affordances (1979) James J. Gibson The affordances of the environment are what it offers the animal, what it provides or furnishes, either for good or ill. Gibson argued that perception is a direct process. The need for perception means that affordances Gibson referred to these opportunities as affordances. The available affordances vary for each individual and depend on the individual's abilities, intentions and the characteristics of the . Gibson's theory rightfully points out that we can gain a lot of information and make accurate judgements based on sensory data, especially in natural environments. "The Theory of Affordances" The Ecological Approach to Visual Perception. It is also unclear how affordances work. Sensory information (light) in the environment meets the retina; it is transformed into electrical impulses and processed in the visual cortex as a conscious experience of seeing. "The Theory of Affordances." An affordance, according to Gibson, is "a specific combination of the . Gibson's ( 1979) theory of affordance provides a theoretical framework for understanding the mutual and functional interrelationship between the organism and its environment. Briefly define the term Affordance (two sentences maximum): 2. Gibson's theory proposes that perception is a bottom-up process. ivy is sometimes mistaken for ivy, and that acid can be taken for water" (81). Gibson's theory (1966) challenged the constructivist view; he proposed there is no need for interpretation or inference as sensory data is sufficient in itself. It is the theory of affordances that lays the foundation for sports coaching methodologies, but also other fields. So information is information about surfaces. Our perception evolved to make sense of rich sensory stimuli embedded in even richer contexts. can also be misperceived. What are Affordances? 5. Inference means making conclusions or guesses about what we perceive based on the sensory data we have. James J. Gibson From: The Ecological Approach to Visual Perception Chapter 8 THE THEORY OF The sub-contents are -Optic ArrayPerception as Bottom up ProcessInvariant . In the affordance theory, Gibson states that only humans change their environment in a natural way. There is enough information in our environment to make sense of the world in a direct way. Affordances are action possibilities in the environment. It looks sturdy and is associated with sitting. Example, a hidden door. In his framework Graver suggests that false affordances exist when action is not possible but the suggestion of action is visible. Therefore, interpretation is necessary to create a mental image of the world around us.

Moreover, he claimed that a person estimates as climbable those steps that are less than 0. Sweetening Ontologies with DOLCE by Aldo Gangemi . Affordances can be hidden as well, and the demand character may be lying (i.e. It is sometimes used as a reference to make something available or to provide something, which would not be accurate in this theory either. interesting pairing with VVs The Theory of Affordances By James J.

Examples of visual items that promote action through the use of affordance theory would include an elevator call button, a door knob, the steering wheel of a car, or the mouse for a computer. . document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Your email address will not be published. Optic flow, texture gradient, affordances. a set of affordances (how one lives rather than where, rather than What is Gibson's theory of direct perception? Status as a Theory of Teaching Affordance Theory can be construed as a theory of teaching, albeit a version in which teaching is about influencing rather than causing, conveying, or directing. In this way, Gibson's theory of affordances is a theory of access. As such, an affordance is not a "property" of an object (like a physical object or a User Interface). By registering you get free access to our website and app (available on desktop AND mobile) which will help you to super-charge your learning process. its substance and its surfaces taken with reference to an animal" (67). For Gibson, however, affordance does not have this demand character the relationship between the objects, the substances, the surfaces, the animals and the people in the environment does not depend on the observers recognition of its affordance (77). In one experiment, participants were told to watch a video of people passing a basketball between them and focus on counting how many times the ball was passed between people in white shirts but not black shirts. Graver also distinguishes that when no action and no perception of action is present then this is known as correct rejection. Aronin and Singleton, 2010; Singleton and Aronin, 2007; Dewaele, 2010). Affordance theory may have started by defining what is physically possible, based on visual cues, but it now applies in various fields to incorporate all action possibilities including those of which an individual may not be aware. For example, we can sit on a chair, stand on it or move it. Direct perception was proposed to be innate rather than learnt. For example, when we see a chair we also perceive potential actions we can take in relation to it like sitting, standing on the chair or moving the chair. The theory of affordances. The process of perceiving affordances is not the same for all people sharing the same space and objects as others' bodily features differ from ours. Finally, for Gibson, affordances in our environment can be misperceived by either failing to perceive something which exists or perceiving something which is not present. Summary: Affordance theory states that the world is perceived not only in terms of object shapes and spatial relationships but also in terms of. There has been quite a large misunderstanding or misinterpretation between the two definitions of affordances created by Gibson and Norman. These changes to road markings promote safe driving. environment (70). May-Aug 2018;31(2):87-94. doi: 10.4103/efh.EfH_33_18. 1977. If we see a chair, we also perceive the affordances of a chair. Perception likely evolved to allow animals to respond to the environment quickly. James J. Gibson coined the word "affordance" to describe the opportunities for action that are available in the world for any particular creature, describing them as "properties of the environment relative to an animal" (Gibson, 1966, 285).This term has been adapted across a wide range of disciplines, including cognitive science, design, education, human-computer . intensities of the user. View Gibson The Theory of Affordances.pdf from PSYCH 124B at University of California, Los Angeles. Summary. 6.10. What is the role of inference in Gibson's theory of direct perception? affordance, according to Gibson, is "a specific combination of the properties of The phenomenological object is entangled with the suitability to habituated action (action likely to be carried out in kind by Gibson's (1966) theory addresses some of the limitations of the constructivist approach, which undermined the direct role of sensory data. In this respect, he claims that behaviour affords behaviour, generating interactivity, such as touching, speaking, striking. [Gibson, James J.] In design we use visual cues to suggest affordances. This is better explained by the direct theory of perception. habitat). As a user experience designer we design for usefulness by creating affordances that match user goals. This article describes the key ideas of the influential psychologist Eleanor J. Gibson, developed over 70 years of research with infants, children, adults, and a wide range of nonhuman species. Visual cues can be community-based, which encourages multiple people to take actions around the same time. An affordance is a clue within the environment that becomes a trigger for an action to be taken. Unlike Gregory and the Gestalt theorists, Gibson sees real movement as a vital part of perception. According to McGrenere and Ho Gibson has explained affordance as an action possibility available in the environment to an individual, independent of the individual's ability to perceive this possibility. "For Gibson, humans, along with animals, insects, birds, and fishes, orient to objects in their worldin terms of what he called their affordances: the possibilities that they offer for action" (447) and it is this central idea that Hutchby transposes to technology and sociology. What are the strengths of Gibson's theory of direct perception? Gibson's theory oers environmental psychology a . American psychologist James Jerome Gibson was influential in changing the way we consider visual perception. In the last decade, the term "affordance," coined by the ecological psychologist James Gibson (1986), has become a buzzword in CALL research. Bottom-up processing is data-driven and fully based on sensory information. Affordance Theory Explained Proposed by James J. Gibson, affordance theory is an examination of how each person visually perceives their environment. Bottom-up processing is. }. According to Gibson sensory data is by nature ambiguous and incomplete. However, critics point out there are a few problems with this approach as well. . Previous knowledge is used to make guesses and interpret sensations that we experience. From the analysis, we know that although the Information System discipline was a relatively late adopter, there is a large space to explore affordances in . Gibson observed that as we move, we receive rich information about depth and distance directly and with no inference about the visual cues required. ^Is Gibsons a modernist project dependent on restrictive (or regular) Some have argued that most affordances result from learning rather than innate knowledge. Gibson suggests that people modify their environments so it can best meet their needs. They are a part of nature: they do not have to be visible, known, or desirable. Sometimes we don't perceive everything in our environment directly e.g. Perception also occurs relatively fast; we can respond to the environment almost instantaneously, which the direct theory of perception better explains. By understanding what we see in our environments, we can learn more about the actions we decide to take and the reasons behind those actions. Shaw and J. Bransford, eds. Treating the social world as separate of the material world is therefore a mistake because humans use the same tools to promote social comfort as they do to create physical comforts. There "Seeing in Third 44.1 Abstract. (75): interaction, animation and The most familiar living environment is a "home," which includes various affordances. In the section titled, "The Origin of the Theory of Affordances," Gibson as distinguished from values the debate does not apply. Summary. Sensory data is rich and sufficient to create a complete representation of the environment without inference. le. patterns of human behavior? Gibson argued that perception is a learnt process that relies on our previous knowledge and experience. R.E. ( JJ ) Gibson (1904-1979) was an American experimental psychologist, author, and theorist. Gibson's theory proposed that inference is not needed in the process of perception, as the sensory data is sufficient in itself to allow accurate perception. The goal is make the environment comfortable, have movement, and create the conditions necessary to achieve personal or household goals. For affordances Are affordances incompatible with After observing water going down a waterfall for some time, if we shift our gaze to the rocks near the waterfall, we can perceive them moving upwards, in the opposite direction to the movement of water we were observing. Gibson suggests that what people see will lead to a decision that they make. inattentional blindness. Hilldale, USA 1 (2), pp. Gibson, James J.

Key phrases: Koffkas "demand character" (77), Kurt Lewins othering Still, after being primed with another stimulus we can suddenly make sense of them (e.g. Gibson is influenced by the theory of valences developed by the Gestalt psychologists, for whom the relationship between the above listed things from the environment is subject to the needs of the observer. Moreover, the information environment provides is sufficient to lead to perception directly. The concept of affordances originating in Gibson's work (Gibson, 1977) is gaining ground in multilingualism studies (cf. Niche, however, guides us toward an Affordances can also be deliberately restricted. Perception is the conscious experience of sensation (e.g. The ridges on a bottle cap help to provide a grippable surface, flat plates on a door at hand height suggest that the door can be pushed, and so on. The pattern of light that provides unambiguous information about the layout of objects. situates affordances in work by Gestalt psychologists. Some stimuli themselves (e.g. The word "affordance" was originally invented by the perceptual psychologist J. J. Gibson (1977, 1979) to refer to the actionable properties between the world and an actor (a person or animal). Print. They look at a favorite book, a comfortable chair, or even an area of physical space, like a man cave, and have a preference for enjoying those items. Affordances are the possibilities for action offered by the environment. Affordances are the opportunities to act that the environment offers. And afforded actions will not be carried out if the user does not perceive them. Hillsdale, N.J.: Elrbaum, The theory of affordances ( Gibson, 2014) offers a framework for considering the child-environment interaction since this theory concerns the individual's perception of the environment. Based on the data from top journals, we reviewed 111 papers from Information Systems, Organization Studies and Management literatures on affordances according to the method of bibliometrics. It was there that he established the idea that affordances were the properties of an object that allow it to function. We challenge interpretivist notions of affordance: while teachers recognise . bump-into-able or get-underneath-able, or climb-on-able, or fall-off-able" (68). Required fields are marked *. Motion parallax tells us about the distance of objects in relation to us. The opposite can also be true. When designing a system or an interface we can use visual cues to suggest to the user that he/she can carry out an action. Although first mentioned in ' The Senses Considered as Perceptual Systems' , it was brought to wider awareness in his seminal 1979 work: ' The Ecological Approach to . Natural illusions limit this argument. He discussed the meaning of perception through his theory of affordances. Boston: Houghton Mifflin, 1979. . He and his wife, Eleanor J. Gibson (1910-2002), a major scientific figure in her own right developed an extensive theoretical body of work on what they called ecological perception and learning. When we are in a noisy environment like a party, we can still focus on a conversation we might be having and tune out the noise we are surrounded by. afford activities (^events afford exigence). Instead, an affordance is defined in the relation between the user and the object: A door affords opening if you can reach the handle. The Theory of Affordances (1979) J. J.

Spackman Current Opinion in Environmental Sustainability 2022 This means attaching particular meaning to visual information. What are the 3 main forms of direct perception? middle space between the subjective and objective, according to Gibson (69). Gibson's seminal essay introduces the term, affordances, and articulates the nuances in its application to ecological psychology. Affordance. Gibson proposed the theory of affordance referring to the mutuality of animal and environment. This process is one-directional; information flows from the environment to specific areas of our brain. An Summary: Positive and Negative Affordances (76): "There has been endless debate }. You may remember the famous blue vs white dress illusion that became viral in 2015. They can also be indirect, performed unconsciously, or only pursued after giving what has been visually perceived a full examination through sensory processing. These are inherent properties of computer technology that constitute possibilities for teachers to act to enable learning in classroom contexts. For instance, a postbox affords letter-mailing to humans, whether the person perceives it or not or as Gibson puts it: The object offers what it does because it is what it is (78). and misperceiving affordances. However, he is careful to add that the specific affordances are inseparable from our body affordance is also uniquely suited to a given animal (79). Sensory data is rich and complex; it is sufficient to make accurate judgments about the environment. Motion parallax is a monocular depth cue. That reduces the chances of a mistake happening or a misperception occurring. Gibson's Affordances Authors: James Greeno University of Pittsburgh Abstract Gibson developed an interactionist view of perception and action that focused on information that is available in. That might range from being able to successfully raise children to the desire to have enough illumination at night within a home so that a person could read a book. To Gibson, affordances are a relationship. . Bottom-up processing, StudySmarter Originals, Alicja Blaszkiewicz. Langfeld who had taught Gibson's experimental psychology course. Introverts may use visual cues for comfort that are primarily personal items. Such as a rigid bottle cap allows for twisting, a hinged door allows for pushing or pulling, and a staircase allows for ascending or descending. Gibson's theory accounts for the fact that a . By gradually putting lines painted on roads closer and closer together drivers can be made to think that they are speeding, which can cause them to slow down. one world or the other inasmuch as they theory of two worlds is rejected. Gibson's theory of perception is information-based rather than sensation-based and to that extent, an analysis of the environment (in terms of affordances . By clearly defining both Norman and Gibsons definitions of the word affordance we can distinguish between the utility, usefulness, and usability of an object, product, or service. His goes on to analyze the affordance of substances by claiming that the air affords breathing, while, after the application of his theory to surfaces and layouts, he claims that the ground affords standing on it. Such as a cardboard chair. The direct theory of perception argues that perception is innate rather than learnt. there may be a shark under the calm water) (82). Gibsons seminal essay introduces the term, affordances, and hidden dalmatian dog optical illusion). You can notice buildings or trees in the distance move significantly slower than the trees and objects that are right next to the road. The constructivist theory of perception posits that we make guesses about what we see not only based on the sensations we receive but also on our expectations and past knowledge. I have made it up. They can be perceived directly. He invokes valence, Perceiving, Acting, Direct, meaning sensations themselves are enough to create a complete representation of the world around us. sense, applying differently according to the physiological tendencies of an And while niches are not, strictly speaking, places, they involve In this respect, he claims that behaviour affords behaviour, generating interactivity, such as touching, speaking, striking. Some people perceived the same image of a dress as blue and black while others as white and gold, while the picture remained the same. In the constructivist view, we don't perceive the world directly. It was there that he established the idea that affordances were the properties of an object that allow it to function. The verb to afford is found in the dictionary, but the noun affordance is not. Summary: Affordance theory states that the world is perceived not only in terms of object shapes and spatial relationships but also in terms of. than the geographical object. Be perfectly prepared on time with an individual plan. The affordances of the environment are what it offers the animal, what it provides or furnishes, either for good or ill.Gibson (1979).

This video describes about Gibson's Theory of Perception with diagrams and videos. I mean by it something that refers to both the environment and the animal in a way that no existing term does. The concept of affordance is a central component of the ecological psychology of J. J. Gibson (1966, 1977, 1979/1986). From his observations he concluded that affordances were about the naturally occurring and actionable relationships between the world and an actor. occupation and suitability (even sustainability?). . How does Gibson describe sensory data in his theory of perception? "Now just as surfaces are stand-on-able and sit-on-able so also are they But the material in which it was designed may not support actual sitting. Affordances were first observed by psychologist James J. Gibson and written about in his 1977 article The Theory of Affordances. According to his theory, perception of the environment inevitably leads to some course of action Affordances, or clues in the environment that indicate possibilities for action, are perceived in a direct, He draws from nature and the environment to postulate his theory of affordances, which is defined as a specific combination of the properties of its substance and its surfaces taken with reference to an animal (67). Given the ties to perception (and ecological optics), this is an James J. Gibson, James J. Gibson analyzes the manner in which the values or meanings of things in the environment could be directly perceived (67). Gibson also was influenced by James' neutral monism, nothing is solely mental or physical. the affordance concept as it evolved throughout Gibson's career, and notes how the theory was explicitly a work in progress, "subject to revision" (Gibson, 1971, in Reed & Jones (eds.
