Neste artigo, defendemos que o conceito de apropriação (tecnológica) é central para se compreender a influência, no Ensino Superior, das tecnologias vulgarmente associadas à chamada “Web 2.0”. Fazemos uma associação entre o conceito de apropriação e a ideia de “affordance” (i.e. a percepção que as pessoas têm acerca das possíveis utilizações de uma ferramenta ou utensílio). À luz destes conceitos, analisamos as características de um subconjunto de ferramentas de Web 2.0 (e.g. Wikis, Blogues), e as potencialidades resultantes, para o Ensino Superior, das dinâmicas específicas do processo de apropriação tecnológica destas ferramentas. The authors defend that the concept of (technological) appropriation is a key term to understand the Web 2.0 tools in Higher Education. They make a strong case from the necessity to relate the concept of appropriation with that of affordance (i.e. the perceived potential utilization of a tool). Based on these concepts, the authors inspect the properties of a sub-set of Web 2.0 tools (e.g. Wikis, Blogs), and they reflect upon the impacts in Higher Education resulting from specific technological appropriation dynamics.

Para a estruturação e qualificação do pensamento criativo alguns educadores sugerem a utilização de modelos de aprendizagem baseados na ampliação das capacidades associativas dos alunos. Neste cenário emerge a Teoria das Affordances como ferramenta, tanto para compreender como o indivíduo interage com os objetos, quanto para ampliar essa interatividade. Focando um design orientado para a ampliação da utilidade dos produtos, o presente estudo explora a aplicação da Teoria das Affordances como estratégia para identificar novas possibilidades de uso dos objetos e analisa como esta aplicação interfere no processo criativo de alunos de Design. O delineamento experimental baseou-se no Plano de Quatro Grupos, de Richard Solomon, e os participantes do estudo exploratório foram alunos de cursos de graduação em Design de quatro instituições privadas de ensino brasileiras. A análise qualitativa e quantitativa dos dados sugere que a exploração de affordances em sala de aula, ao induzir a abstração, potencializa a emergência de alternativas de uso que, incorporadas ao processo de design, podem conferir versatilidade e aumentar as possibilidades de inovação na concepção de produtos. Os resultados da pesquisa deverão ser ainda ulteriormente confrontados com resultados de novos testes para que seja possível confirmar as hipóteses sobre a importância do uso de associações estruturadas (affordances) no ensino e no processo de design de produtos.; To qualify creative thinking...

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); The aim of this paper is to analyze the concept of social affordance in the context of Ecological Philosophy. In particular, we analyze the hypothesis that social affordances emerge from the collective perception of information available in the environment. We analyze Schmidt’s hypothesis (2007) that the meaning of social affordances is neither exclusively in the perceiver nor only in the physical environment, but it is a constituent part of its ecological niche. The niche is characterized as the sum of ecologicalinformational relations between organisms and environment, having social properties which are responsible for constituting social affordances. We argue that the concept of social affordances enables the Ecological Philosophy to develop a comprehensive view about the physicalist perspective in Philosophy of Mind. From the methodological perspective the concept of social affordance aggregates ecological and semantic features providing elements to explain various forms of adjustments and laws that guide the action of organisms.; Este trabalho tem como objetivo realizar um estudo do conceito de affordances sociais no contexto da Filosofia Ecológica. Em especial analisamos a hipótese de que...

Tese (doutorado)—Universidade de Brasília, Instituto de Psicologia, 2008.; A discussão sobre as inter-relações entre o ser humano e o seu ambiente físico tem sido ressaltada nas duas últimas décadas. Essa inter-relação é investigada por diversos ângulos, compreendendo as questões ecológicas e a relação com o ambiente como um todo. Baseado em referenciais da Psicologia do Desenvolvimento e da Psicologia Ambiental investigou-se a relação de adolescentes com o seu ambiente. A Psicologia do Desenvolvimento forneceu subsídios para a conceituação e contextualização da adolescência. A Psicologia Ambiental contribuiu com os conceitos de affordance, behavior setting e cultivação. Os objetivos específicos foram: descrever o comportamento observável de adolescentes em interação com o ambiente, caracterizar os conceitos que os jovens apresentam quanto a esta interação, verificar se a relação do jovem com o ambiente está centrada no momento atual de suas vidas ou se está ligada ao seu passado e/ou ao futuro. Participaram 180 jovens, sendo metade do Movimento Escoteiro do Distrito Federal e metade do Programa Segundo Tempo nos Esportes, com idades variando entre 11 e 18 anos. A pesquisa foi realizada em três fases: método de observação do comportamento; instrumento de conceitos ambientais e entrevistas semi-estruturadas. Os resultados indicam que as inter-relações desses jovens com o ambiente são caracterizadas por justificativas de interesse pessoal e que as affordances identificadas são relacionadas às necessidades dos participantes. Para os jovens...

Partindo de uma reflexão sobre a multiplicidade disciplinar, teórica, metodológica e terminológica e utilizando uma analogia com o modelo multivariado da correlação canônica, propõe-se o rótulo Estudos Pessoa-Ambiente para englobar as diferentes sub-áreas disciplinares e temáticas que lidam com as relações recíprocas pessoa-espaço físico. Segue uma discussão de quatro conceitos do espaço (espaço pessoal, territorialidade, apinhamento e privacidade) e sua relação com mobilidade. Após algumas considerações sobre affordance sugere-se o elo mobilidade-affordance como elemento molecular da relação recíproca pessoa-espaço físico no cerne dos estudos pessoa-ambiente.

An important question for the study of social interactions is how the motor actions of others are represented. Research has demonstrated that simply watching someone perform an action activates a similar motor representation in oneself. Key issues include (1) the automaticity of such processes, and (2) the role object affordances play in establishing motor representations of others’ actions. Participants were asked to move a lever to the left or right to respond to the grip width of a hand moving across a workspace. Stimulus-response compatibility effects were modulated by two task-irrelevant aspects of the visual stimulus: the observed reach direction and the match between hand-grasp and the affordance evoked by an incidentally presented visual object. These findings demonstrate that the observation of another person’s actions automatically evokes sophisticated motor representations that reflect the relationship between actions and objects even when an action is not directed towards an object.

According to the task-affordance hypothesis, people will be more likely to use a specific strategy as tasks more readily afford its use. To evaluate this hypothesis, we examined the degree to which older and younger adults used a self-testing strategy to learn items, because previous studies suggest that age-related differences in the use of this powerful strategy vary across tasks. These tasks (words affixed to a board vs. pairs on flashcards) differentially afford the use of the self-testing strategy and may moderate the age-related effects on strategy use. Participants performed a recall-readiness task in which they continued to study items until they were ready for the criterion test. As predicted, self testing was used less often on tasks that least afforded its use. Namely, participants used self testing less when they studied single words affixed to a board than when they studied pairs on flashcards. Most important, age-related deficits in strategy use were greater for the former task and nonexistent for the latter one, suggesting that task affordance moderates age differences in strategy use.

Viewing objects can result in automatic, partial activation of motor plans associated with them—“object affordance”. Here, we recorded grip force simultaneously from both hands in an object affordance task to investigate the effects of conflict between coactivated responses. Participants classified pictures of objects by squeezing force transducers with their left or right hand. Responses were faster on trials where the object afforded an action with the same hand that was required to make the response (congruent trials) compared to the opposite hand (incongruent trials). In addition, conflict between coactivated responses was reduced if it was experienced on the preceding trial, just like Gratton adaptation effects reported in “conflict” tasks (e.g., Eriksen flanker). This finding suggests that object affordance demonstrates conflict effects similar to those shown in other stimulus–response mapping tasks and thus could be integrated into the wider conceptual framework on overlearnt stimulus–response associations. Corrected erroneous responses occurred more frequently when there was conflict between the afforded response and the response required by the task, providing direct evidence that viewing an object activates motor plans appropriate for interacting with that object. Recording continuous grip force...

Some objects in our environment are strongly tied to motor actions, a phenomenon called object affordance. A cup, for example, affords us to reach out to it and grasp it by its handle. Studies indicate that merely viewing an affording object triggers motor activations in the brain. The present study investigated whether object affordance would also result in an attention bias, that is, whether observers would rather attend to graspable objects within reach compared to non-graspable but reachable objects or to graspable objects out of reach. To this end, we conducted a combined reaction time and motion tracking study with a table in a virtual three-dimensional space. Two objects were positioned on the table, one near, the other one far from the observer. In each trial, two graspable objects, two non-graspable objects, or a combination of both was presented. Participants were instructed to detect a probe appearing on one of the objects as quickly as possible. Detection times served as indirect measure of attention allocation. The motor association with the graspable object was additionally enhanced by having participants grasp a real object in some of the trials. We hypothesized that visual attention would be preferentially allocated to the near graspable object...

Action understanding lies at the heart of social interaction. Prior research has often conceptualized this capacity in terms of a motoric matching of observed actions to an action in one’s motor repertoire, but has ignored the role of object information. In this manuscript, we set out an alternative conception of intention understanding, which places the role of objects as central to our observation and comprehension of the actions of others. We outline the current understanding of the interconnectedness of action and object knowledge, demonstrating how both rely heavily on the other. We then propose a novel framework, the affordance-matching hypothesis, which incorporates these findings into a simple model of action understanding, in which object knowledge—what an object is for and how it is used—can inform and constrain both action interpretation and prediction. We will review recent empirical evidence that supports such an object-based view of action understanding and we relate the affordance matching hypothesis to recent proposals that have re-conceptualized the role of mirror neurons in action understanding.

Evaluating the affordance–control interpretation of the relationship between performance and object estimation has been proposed by psychophysical and psychonomic studies. This study examined the weight estimation–performance relationship. Individuals with visual impairment or blindness put shots that varied in weight among five scales. In Experiment 1, only the perceived weight was a significant performance constraint. In Experiment 2, the weight was perceived as heavier when the participants’ actions were manipulated through cognitive interpretation. The increase in perceived weight appeared to be related to performance and intrinsically scaled to the action, even when the action was only mental rather than physical. The study’s findings suggest that bodily experience and action are the basis for physical judgments and likely underlie other basic cognitive interpretations of sensory stimuli. This suggestion goes hand in hand with the biofunctional approaches which assume direct experience of the integrated wholeness of one’s body is fundamental for developing other kinds of awareness. Different perspectives from oriental philosophy and psychology are also discussed.

Stimulus position is coded even if it is task-irrelevant, leading to faster response times when the stimulus and the response locations are compatible (spatial Stimulus–Response Compatibility–spatial SRC). Faster responses are also found when the handle of a visual object and the response hand are located on the same side; this is known as affordance effect (AE). Two contrasting accounts for AE have been classically proposed. One is focused on the recruitment of appropriate grasping actions on the object handle, and the other on the asymmetry in the object shape, which in turn would cause a handle-hand correspondence effect (CE). In order to disentangle these two accounts, we investigated the possible transfer of practice in a spatial SRC task executed with a S–R incompatible mapping to a subsequent affordance task in which objects with either their intact handle or a broken one were used. The idea was that using objects with broken handles should prevent the recruitment of motor information relative to object grasping, whereas practice transfer should prevent object asymmetry in driving handle-hand CE. A total of three experiments were carried out. In Experiment 1 participants underwent an affordance task in which common graspable objects with their intact or broken handle were used. In Experiments 2 and 3...

Approved for public release; distribution is unlimited; This research investigated the development and use of an analytical assessment methodology anchored in systems engineering principles, affordance theory, and human abilities, to measure the potential of integrated training environments (ITEs) to effectively support training. Empirical investigation of ITEs is costly, lacks formal guidance, and is therefore often unreliable. Ad hoc studies, commissioned by individual organizations, constitute the current state of Army ITE evaluation. These assessments are often entirely based on subject matter expert judgment through surveys, which produce results that are linked indirectly and loosely to the ITEs. What is required is a repeatable, inexpensive, analytical approach to ITE assessment that bounds the potential of a given system to the support it provides to the deliberate practice of specific tasks. The results of this research include the development and use of the integrated training environment assessment methodology (ITEAM). ITEAM was used to evaluate the ability of several ITEs to support the deliberate practice of specific tasks during training. The dissertation shows that ITEAM consistently predicted where training was supported by an ITE and generally how well. ITEAM is offered as a tool to be used early in the acquisition process to affordably define and verify the requirements of candidate ITE solutions for Department of Defense needs.

Our everyday interactions with the world are subject to affordance: the interaction that exists naturally between an object and the action possibilities inherent within it. Object affordances result from complex visuomotor interactions and are reflected in many processes, including reaching and grasping behaviours, distance judgments, and object identification. With the present study we extended current research on the use of affordances in visual searches of arrays to investigate whether guidance by affordance occurs in searches of real-world scenes and is the result of knowledge of target function (Experiment 1), and whether it is integrated with the use of scene context in guidance of search (Experiment 2). To investigate the contribution of object function to guidance by affordance in real-world scenes we tracked participants’ eye movements while they performed visual searches. The target objects were invented objects with invented functions that were learned by the participants prior to beginning search. By providing participants with information about only the features and functions of targets (and not about location) we omitted any effects on search from previously learned associations between the objects and their locations in the scene. This allowed us to examine guidance by affordance independently of traditional contextual effects. In Experiment 1 we compared the searches of participants who learned the functions of the targets to those who learned only the targets’ features. Results showed facilitation of visual search by knowledge of target function as compared against searches in which target function was not known. Experiment 2 compared searches for objects placed in locations congruent and incongruent with their function to show that guidance by affordance is benefitted by knowledge of target function in congruent searches. We concluded that guidance by affordance results from an understanding of the function of an object and the integration of that understanding into an understanding of the context of the scene as a whole; Thesis (Master...

Le travail présenté dans cette thèse porte sur le rôle du cortex prémoteur dorsal (PMd) au sujet de la prise de décision (sélection d’une action parmis nombreux choix) et l'orientation visuelle des mouvements du bras. L’ouvrage décrit des expériences électrophysiologiques chez le singe éveillé (Macaca mulatta) permettant d’adresser une fraction importante des prédictions proposées par l'hypothèse des affordances concurrentes (Cisek, 2006; Cisek, 2007a). Cette hypothèse suggère que le choix de toute action est l’issue d'une concurrence entre les représentations internes des exigences et des atouts de chacune des options présentées (affordances; Gibson, 1979). Un intérêt particulier est donné au traitement de l'information spatiale et la valeur des options (expected value, EV) dans la prise de décisions. La première étude (article 1) explore la façon dont PMd reflète ces deux paramètres dans la période délai ainsi que de leur intéraction. La deuxième étude (article 2) explore le mécanisme de décision de façon plus détaillée et étend les résultats au cortex prémoteur ventral (PMv). Cette étude porte également sur la représentation spatiale et l’EV dans une perspective d'apprentissage. Dans un environnement nouveau les paramètres spatiaux des actions semblent être présents en tout temps dans PMd...

The visualization of tools and manipulable objects activates motor-related areas in the cortex, facilitating possible actions toward them. This pattern of activity may underlie the phenomenon of object affordance. Some cortical motor neurons are also covertly activated during the recognition of body parts such as hands. One hypothesis is that different subpopulations of motor neurons in the frontal cortex are activated in each motor program; for example, canonical neurons in the premotor cortex are responsible for the affordance of visual objects, while mirror neurons support motor imagery triggered during handedness recognition. However, the question remains whether these subpopulations work independently. This hypothesis can be tested with a manual reaction time (MRT) task with a priming paradigm to evaluate whether the view of a manipulable object interferes with the motor imagery of the subject's hand. The MRT provides a measure of the course of information processing in the brain and allows indirect evaluation of cognitive processes. Our results suggest that canonical and mirror neurons work together to create a motor plan involving hand movements to facilitate successful object manipulation.

Dissertação de Mestrado em Ensino de Educação Física, nos Ensinos Básico e Secundário; As possibilidades de ação, denominadas por Gibson (1979) de affordances, dependem do ajuste entre as características corporais do indivíduo e as características do ambiente, utilizando o conhecimento das suas próprias dimensões corporais para executar todo o tipo de ações do dia-a-dia, como subir escadas, atravessar barreiras, agarrar objetos etc. A passagem por aberturas estreitas (portas) é um exemplo de affordance. A passagem é propiciada quando as aberturas são mais largas que a maior dimensão corporal horizontal (largura dos ombros), e quando a abertura é mais pequena, para evitar a colisão, verifica-se uma rotação dos ombros. Nos adultos, o ponto crítico (< 1.3) estimado por Warren e Whang (1987) na passagem pelas aberturas, resulta do rácio largura ombros/abertura, indicando que este é maior que um para deixar uma margem de segurança que permita as variações laterais na trajetória do tronco que estão presentes durante a marcha. Com base nestes pressupostos, esta investigação teve como objetivo geral: estimar as variáveis preditoras do rácio crítico de transição para uma nova categoria de ação na passagem de aberturas estreitas em crianças com idades compreendidas entre os 6.5 e os 10.5 anos. Como objetivos específicos foram definidos: (i) - estimar o rácio crítico de rotação dos ombros em crianças com idades compreendidas entre os 6.5 e os 10.5 anos na passagem de uma abertura; (ii) - comparar o rácio crítico de rotação dos ombros...

Today, there are two major paradigms for vision-based autonomous driving systems: mediated perception approaches that parse an entire scene to make a driving decision, and behavior reflex approaches that directly map an input image to a driving action by a regressor. In this paper, we propose a third paradigm: a direct perception approach to estimate the affordance for driving. We propose to map an input image to a small number of key perception indicators that directly relate to the affordance of a road/traffic state for driving. Our representation provides a set of compact yet complete descriptions of the scene to enable a simple controller to drive autonomously. Falling in between the two extremes of mediated perception and behavior reflex, we argue that our direct perception representation provides the right level of abstraction. To demonstrate this, we train a deep Convolutional Neural Network using recording from 12 hours of human driving in a video game and show that our model can work well to drive a car in a very diverse set of virtual environments. We also train a model for car distance estimation on the KITTI dataset. Results show that our direct perception approach can generalize well to real driving images. Source code and data are available on our project website.

Dans cet article, notre ambition est d’éclairer la notion d’éligibilité d’un objet patrimonial. Pour cela, nous proposons le concept d’affordance patrimoniale, l’éligibilité devenant d’autant plus probable que l’objet candidat à la patrimonialisation a cette qualité d’affordance. À partir de la distinction de deux types de savoirs et savoir-faire olfactifs observés dans divers milieux professionnels, nous tentons d’identifier une des conditions de la patrimonialisation de ce registre d’expertise dit “immatériel”. Après avoir justifié notre typologie, nous montrons que le premier type de savoirs et savoir-faire olfactifs (type 1: cuisiniers, oenologues, parfumeurs, sommeliers) peut être facilement revendiqué comme un patrimoine parce que, de la part des professionnels, il offre une affordance narrative (il permet un récit de soi racontable et, de ce fait, recevable) alors que cela est impossible avec le second type d’expertise olfactive (type 2: employés de la morgue, fossoyeurs, infirmières, médecins légistes, sapeurs-pompiers, thanatopracteurs) qui n’offre pas une telle affordance.
