Will understanding vision require a wholly empirical paradigm?
Based on electrophysiological and anatomical studies, a prevalent conception is that the visual system recovers features of the world from retinal images to generate perceptions and guide behavior. This paradigm, however, is unable to explain why visual perceptions differ from physical measurements, or how behavior could routinely succeed on this basis. An alternative is that vision does not re...
متن کاملCommentary: Perception and Reality: Why a Wholly Empirical Paradigm is Needed to Understand Vision
A central puzzle in vision science is how perceptions that are routinely at odds with physical measurements of real world properties can arise from neural responses that nonetheless lead to effective behaviors. Here we argue that the solution depends on: (1) rejecting the assumption that the goal of vision is to recover, however imperfectly, properties of the world; and (2) replacing it with a ...
متن کاملA wholly empirical explanation of perceived motion.
Because the retinal activity generated by a moving object cannot specify which of an infinite number of possible physical displacements underlies the stimulus, its real-world cause is necessarily uncertain. How, then, do observers respond successfully to sequences of images whose provenance is ambiguous? Here we explore the hypothesis that the visual system solves this problem by a probabilisti...
متن کاملReply to Walker and Stickgold: Proposed boundary conditions on memory reconsolidation will require empirical verification.
Broadly speaking, nonreplications of the kind we reported (1) can occur for three reasons: (i) the original finding was a false-positive, (ii) the replication was a false-negative, or (iii) some unanticipated variablemoderated the effect. The authors of the original study, Walker and Stickgold (2), now propose several potential moderators (3). We welcome such discussion; however, we should note...
متن کاملBrain tumor stem cells: will understanding a new paradigm lead to improved therapies?
Solid tumors are a complex network consisting of cells at various stages of differentiation, neovasculature structures, reactive inflammatory cells, recruited cells and infiltrated parenchyma that interact within the tumor mass. However, evidence strongly indicates that cancer stem cells (CSCs) drive tumorigenesis, as these cells possess self-renewal and tumorigenic capacity absent in the major...
