Depth perception

Chapter 6 deals with how individuals perceive depth once again this is going to be different for everyone and every eye. This essay will reflect on many of my own thoughts and questions that pertain to this chapter. To begin with I find it interesting that ciliary muscles in and around our eye help to determine our depth. Other cues that exist determine our depth is the monocular and binocular cues. I find these two cues difficult to understand. What exactly is a monocular cue? What exactly is…

A). Perceiving objects in everyday aspects such as a living room with toys all over the floor, or a plate on the dining room table requires you to determine where the object begins and where it ends as you are measuring how much depth the item has (Gross, 167). You recognize the edges of each object as well as the belonging of each individual item to the tied environment. As infants grow up, they develop these abilities to be able to develop shadows to where the items edges are tied to the…

Results Clinical and imaging findings Proband case (case III:3) We examined a 6-year-old male and his affected brother, sister, mother and maternal grandmother, and his unaffected father (Figure 1 - Pedigree). This patient was referred to our institution for further evaluation of blurred optic disc margins bilaterally noted on a routine eye exam. Of note, he had a past medical history relevant for abdominal migraines and a 9 millimeter in diameter complex pineal cystic gland, incidentally…

Critical period plasticity vs Plasticity throughout life In neuroscience they mention that there is two types of plasticity during our lifetime, critical period plasticity being the first during our postnatal development, then comes plasticity. Critical period plasticity is a particular time frame in which the brain development is sensitive to a certain experience such as vision, and once the critical period ends there is no more plasticity occurring (Kolb and Whishaw, 270). On the contrary…

Daylight saving is when we spring forward an hour at 2:00 am on Sunday, March 12, and fall back an hour on November 5 (2:00 am). Daylight savings originally began in during WWI in order to reduce the amount of fuel consumed by artificial lighting. It was then removed until WWII. But WWII is long over so why do we still have it? Most people think that it helps with safety, less car accidents if there is daylight at the end of the day. However, this “benefit” only comes at the cost of the loss of…

fueled by a sugar-induced hysteria. All five cradled ice cream cones, exuberantly embracing each other with sticky hands. Crisp pine trees lined the path through camp, framing the elated chaos. With a click, I stopped down the aperture, extending the depth of field and drawing each member of my wacky sixth grade group into focus. Hitting the shutter, I captured my composition of carefree elation. Although I created this image within a fraction of a second, the joyous frenzy it encapsulates took…

Richard Learoyd is a British photographer, born 1966 – present, who utilizes a particular photographic processes called camera obscura, Latin translation “dark room,” to create his works of art. Learoyd designed and built his own room-sized portable camera obscura which sits adjacent to room his subject possess – separated by a singular lens. During this process, light falls upon the subject and is instantly fixated onto the photographic paper, no negative is produced. Learoyd’s approach to the…

concept within the topic of perception is the ability to become deceived by our own minds. The Ames room tells us that human perception is easily distorted and can lead to us seeing things that aren’t really what they appear to be. The Ames room trickers the observer into thinking that the room they are looking into is a regular cubic roo, this is our brain deceiving us into believing something that is not true. With regards to what this tells us about human perception is that we use the context…

brain system that provides for the temporary storage and manipulation of information necessary for some of our more complex cognitive tasks. If we are to interpret this definition in terms of our perceptions and experiences, we will say that our working memory is the method through which our perceptions are able to be translated into our experiences. Therefore, when we perceive these short momentary points in time, these are encoded into our working memory, which helps us produce a…

Questions 1. What problem does the visual system face when perceiving depth? Hint: think about proximal and distal stimuli. (5 pt.) When our visual system perceives depth it uses distal stimulus and proximal stimulus. This is problematic because the distal stimulus and/ or environmental stimuli are three dimensional but the proximal stimuli hitting your retina are two-dimensional Therefore, in order to perceive depth your brain needs to interpret the two-dimensional stimuli as three dimensional…
