Understanding Perception

One of the greatest influences on the concept of perception was made by Gestalt psychologists and their viewpoint of the mind as holistic, constructing wholes (perception) from parts (sensory information from the external world). The combination of Aristotle's bottom-up, sensory driven empiricism and Plato's top-down, rationalism proved to be a starting point for what we now understand to be the product of perception. Our minds constant filter information from the outside world, whether we are aware of it or not. It is the cognitive process of attention that determines which information we should be immediately and consciously aware of and which information we can subconsciously store for later processing. Indeed, attention has a large role in shifting out focus to our conscious awareness. The debate about the nature of consciousness can be traced to Descartian thought in his theory of methodological doubt that stated that all we can know is consciousness. However, current neurophysiological research is working hard to better understand consciousness, even when it resides in someone else's head!

Hi,

This one was really difficult so I sincerely hope I was able to capture what was needed.

1). Briefly, discuss how visual information is processed in the brain.

"The visual system is unique as much of visual processing occurs outside the brain within the retina of the eye" (Dragoi, 2013, para 1). The basic process for visual information to move from the eye to the brain where it is processed is complex so the main areas where the information passes through are:
• Retina
• Optic nerve
• Optic chaism
• Lateral geniculate nucleus
• Thalamus
• Visual cortex
"The primary visual cortical receiving area is in the occipital lobe" (Dragoi, 2013, para 7). Within this lobe the information such as color, shape and movement are processed and interpreted. The brain takes all of the ...

Solution Summary

How visual information is processed in the brain is discussed. How the sense of hearing and its sensory information is organized into perceptual and recognizable patterns are given. The cultural and societal expectations and experiences influence the formation of perception are given.
