Philosophical accounts of visual perception have long had to contend with questions of perceptual relativity: visual phenomenology seems to be influenced by factors independent of the objective properties of the external objects we perceive. More recently, a host of such examples has emerged from psychological studies on visual attention. In two prominent accounts of the consequences of this research, Block argues that these effects occur without changes in the way one visually represents the world to be. If true, this would (...) undermine representationalist accounts of the phenomenology of perception, which share a commitment to the claim that phenomenal character supervenes on representational content. Block’s thesis is based on experiments involving non-selective attention, and he draws the metaphysical conclusion that the resources representationalists need to distinguish veridical from illusory perception are nonexistent. The empirical evidence he considers is highly compelling, as is the ‘landscape’ model of attention that appears to underwrite it. However, in discussing these issues, Block also considers a representative example of selective attention, wherein he concedes a point that provides grounds for a plausible representationalist response. I assemble and assess this response, revealing the contradiction at the heart of Block’s thesis, and conclude, that the representationalist should remain unmoved. (shrink)

Uno de los principales desafíos que debe enfrentar el representacionalismo es dar cuenta de manera consistente de la posibilidad de escenarios en que la atención encubierta altera la fenomenología de nuestras experiencias visuales. Este trabajo intenta poner de relieve los compromisos y dificultades internas de tres estrategias representacionales diferentes para enfrentar este desafío: la estrategia de contenidos indeterminados, la estrategia de la ilusión masiva y el proyecto narcisista que apela a propiedades relacionales indexadas a la atención. Se argumentará que este (...) último posee virtudes comparativas evidentes quela literatura ha ignorado y que justifican su desarrollo en profundidad. (shrink)

Resumen La experiencia del dolor suele caracterizarse por su temporalidad, localización, intensidad, por qué tan desagradable se experimenta y la manera particular en el que se siente. Estas últimas son las cualidades sensoriales del dolor. Discuto aquí la tesis representacionista según la cual las CSD se explican por un contenido mental que describe la naturaleza del daño corporal. Desarrollo dos argumentos en contra de la regularidad que tal tesis supone entre las CSD y la naturaleza de la lesión, y presento (...) evidencia a partir del "Cuestionario del dolor de McGill", un instrumento clínico para la comunicación del dolor. Concluyo que la lesión corporal y las cualidades sensoriales del dolor no covarían como supone esta forma de representacionismo.The experience of pain is usually characterized by its location, intensity, temporality, unpleasantness, and sensory qualities. Here I focus on the thesis according to which pain sensory qualities are identical with mental representations of bodily damage. I develop two arguments against this, one based on cases of pain absence and another based on pain variability. In the absence argument, I discuss clinical evidence on episodic analgesia, where individuals experience a painless period of time after being injured. In the variability argument, I discuss the "McGill Pain Questionnaire", evidence in clinical settings which shows how variable the relation between pain and the nature of the injury actually is. I conclude that pain sensory qualities and physical damage do not covary, as the strong representationalism supposes. (shrink)

The overflow debate concerns this following question: does conscious iconic memory have a higher capacity than attention does? In recent years, Ned Block has been invoking empirical works to support the positive answer to this question. The view is called the “rich view” or the “Overflow view”. One central thread of this discussion concerns the nature of iconic memory: for example how rich they are and whether they are conscious. The first section discusses a potential misunderstanding of “visible persistence” in (...) this literature. The second section discusses varieties of attention relevant to this debate. The final section discusses the most prominent alternative interpretation of the Sperling paradigm—the postdiction interpretation—and explains how it can be made compatible with a weaker version of the rich or overflow view.
