Essay on Visual Imagery Psychology To what extent are visual imagery mediated by the same cognitive and neurobiological components? Much research in recent decades has attempted to answer the question as to whether imagination of, for example, visual imagery, involves the same brain mechanisms as actual visual perception.
How do images differ from actual perceptions, and how are they alike?
This paper will summarize evidence which shows that visual imagery not only involves brain activity, but many of the same brain structures that are involved in visual perception are involved in visual imagery as well. A computer model of the cortical visual system and the effects of damage to that system are discussed in some detail.
The interaction between visual perception and visual imagery is also briefly discussed, and its implications for perceptual disorders, such as hallucinations in schizophrenia. Role of the Visual Cortex in Perception. The human striate cortex called V1 or "primary visual cortex" in the occipital lobe of Imagery essay conclusion brain has been long known to be an indispensable component of form perception in the visual system.
In a classic study, Hubel and Wiesel showed that the V1 area in cats primary visual cortex or striate cortex is composed of cells that respond Imagery essay conclusion definite qualities of stimuli, such as a point or line.
The experimenters identified cells as "simple", "complex", or "hyper-complex", depending on the complexity of the stimulus to which they responded, with "hyper-complex" cells often responding only to lines in a certain orientation, for example.
When looking at an object, information is passed from the retina through the brainstem and the thalamus to the visual cortex.
From the primary visual cortex V1 or striate cortex the information is passed to many distinct areas within the occipital cortex. All of the above areas are "retinotopically organized" Ochsner and Kosslyn,meaning that the spatial structure of the object represented corresponds approximately to the image on the retina itself.
A disproportion-ate area of the retina represents the center of the visual field, and this disproportion is represented in all of the other areas to which the information is passed.
Pollen argues that the human striate cortex V1 is not just a relayer of visual information from the brainstem and thalamus, but an "indispensable component" of a neural pathway concerned with achromatic form perception.
They used knowledge about what the visual system can do as a jumping off point. For example, we can recognize a human form in many different postures, such as standing, sitting, squatting, etc. We can also identify objects when they appear in different parts of the visual field, when they subtend different visual angles, when they vary in shape eg.
Their task was to produce a computer model that could perform all of these perceptual tasks. Research had shown that many cognitive processes could be modeled with neural networks. A second goal of the project was to consider numerous neurological syndromes which affect vision, and see if doing damage to the system at various points could shed some insight onto the problem of how lesions or dysfunctions of the brain could produce various neurological syndromes.
Using computer simulations, they were able to show how dysfunctions can arise from the disruption of the various subsystems. To understand their model, it is first necessary to understand their theory of how the visual system of the brain functions, much of which is articulated in other studies.
A Theory of the Functioning of the Cortical Visual System Kosslyn and his colleagues have attempted to form a theory which could explain how the brain processes both perceived and imagined visual data.
A set of retinotopically organized mapped areas are postulated to work together to separate figure from ground, and all of these areas grouped together have been designated as a single structure with a specific function, and have been given the name "visual buffer" Kosslyn, This area consists of many more specialized components, one sensitive to wavelength area V4another to motion, and so on.
Only a small amount of information in the visual buffer can be processed at one time. Thus an internal "attention window" selects patterns in the "visual buffer" for further processing. Ochsner and Kosslyn, ; Kosslyn, Information selected by the "attention window" is sent over two parallel pathways in the cerebral cortex, the ventral, so-called "what" pathway in the inferior temporal lobe, which is concerned with properties of the object, thus determining what the object is, and the dorsal "where" pathway in the posterior parietal lobe, which is concerned with spatial properties of the object, thus determining where the object is with respect to other objects in the field Ungerleider and Mishkin, In order to recognize an object or to imagine itwe must have stored some sort of representation of that object in our brains.
These representations are stored in perceptual encoding systems that store properties of an object from various sense modalities Kosslyn and Koenig,Schacter, This analysis essay explores the use of imagery and displays Bishop’s unmistakable mastery of skill as a poet in the “Filling Station” This poetry analysis essay of the “Filling Station” by Elizabeth Bishop will focus on the use of imagery, symbols, wordplay, and tone.
