Perception versus attention

Attention and Visual Perception: Analyzing Divided Attention

Attention is one of the most active areas of experimental research in cognitive science. This chapter focuses on an aspect of attention that has been studied intensively over the past twenty-five years or so: capacity limitations on our ability to perceive multiple visual inputs. The basic questions are simple but far-reaching. How much visual information can we take in at one time? What can we...

Attention: Effect on Perception

Attention is the mechanism that allows us to select relevant information for processing from the vast amount of stimuli we are confronted with, prioritizing some while ignoring others. Attention can affect perception by altering performance—how well we perform on a given task—or by altering appearance— our subjective experience of a stimulus or object. Visual attention is commonly divided into ...

Reference, perception, and attention

I examine John Campbell’s claim that the determination of the reference of a perceptual demonstrative requires conscious visual object-based selective attention. I argue that although Campbell’s claim to the effect that, first, a complex binding parameter is needed to establish the referent of a perceptual demonstrative, and, second, that this referent is determined independently of, and before...

Attention and visual perception.

Somewhere between the retina and our conscious visual experience, the majority of the information impinging on the eye is lost. We are typically aware of only either the most salient parts of a visual scene or the parts that we are actively paying attention to. Recent research on visual neurons in monkeys is beginning to show how the brain both selects and discards incoming visual information. ...
