Perception, Sensation

The way we perceive objects depends on different things. One thing that changes the way we view things is monocular depth cues. Monocular depth cues are cues on depth perception that are accessible only to one eye at a time. There are actually a couple of different monocular depth cues. The ones that I will cover will be size constancy, aerial perspective, linear perspective, and texture gradient. Size constancy refers to the tendency to perceive an object or objects as the same size regardless of it being near or far. For example, the imagineers at Walt Disney World use this with their Christmas tree to make it appear bigger. At the bottom of the tree, they place ornaments that are huge. Since people see the huge ornaments at the bottom of

Visual illusions is the most common regarding UFO’s sightings because what the person might be seeing can just be a visual illusion and not an actual UFO. This plays a huge role in UFO sightings because most UFO sightings are seen from very far away, making it possible that what most people are seeing is the strong effect of a visual illusion in the sky. For instance, an illusion known as the airplane illusion states that familiar size determines the apparent size and distance of the plane or in this case an object in the sky ( Hershenson & Samuels, 1999). For example, the fact that we are familiar with a plane and expect it to be a certain size and certain speed affects how we perceive the size and speed of the objects in the sky. Therefor, this may affect how we see lights or other objects such as a balloon that seem far away and moving either fast or slow in the

After being taught three chapters of psychology I have encountered a wide range of information that has interested me, but perception has definitely interested me the most. It has interested me the most because ever since I was a kid I wondered why things closer to the car seemed to be moving faster than objects in the distance. Perception is the body's abilities to sense or detect something through its senses. We use perception everyday as it plays a large role in human life due to the fact that almost everything we encounter can be detected by our five senses.

Sound waves: Changes in pressure caused by molecules of air or fluid colliding and moving apart again.

Sense perception is one way that allows us to interact and communicate with each other and the world. This is our primary way of knowing because our senses live experiences that we go through. Based on our senses we are to make interpretations of the world. For example, in class, each pair was given a box. Inside the box, there was one metal ball, but you had to figure out the structure or the form of a maze inside the box. We couldn't see inside the box, and we couldn’t touch the inside of the box. By using our sense of hearing and another way of knowing, imagination, we were able to make an educated guess of what the inside structure of the box looked like.

Only One CONTRAST CAN BE PERCEIVED in ‘REAL TIME’. Therefore, it is impossible to sit & stand, to sleep & be awaken at the same time. What is in a foreground or closer is OVERESTIMATED, & what is in a background & farther away is UNDERESTIMATED. For instance, the light poles alongside turnpike are all the same size - those nearby are perceived as the ‘largest’ those farther back at the horizon are unperceived. (Quote from ‘Livets Bog’ Vol IV, section #

Humans have three cone cells that are extremely sensitive to Red, (620-700nm), Green (490-570nm) and Blue (450-495nm) wavelengths of light. Although these three cones are most sensitive to these wavelengths, they are still sensitive to the remaining wavelengths of visible light between 400-700nm. When a light with a wavelength of 600nm is transmitted through the retina, the Red and Green cones capture, sense and signal the brain that orange light is observed. In this case the Red and Green cones absorb light but the Green cones are less sensitive. Also, the Blue cones don’t absorb much light and are not sensitive

Perception is the process of individuals interpreting their impressions to give meaning to their environment. The concept of perceptual errors is how a person’s behavior is based on their perception of what reality is, not on reality itself. Perception is the process by which an individual selects, organizes, and interprets information inputs to create a meaningful picture of the world. The attribution process guides our behaviour, regardless of the truth of the attribution.

In Marry Shelly’s Frankenstein, perception plays a key part in the monsters’ icy demise. Not only is the story affected by how the villagers perceive the monster, but the readers’ perception, like in any literary work, plays the role of ultimate judge.

The biological processes of colour perception which happen in the brain are innate and contribute towards the way in which individuals view colour. Cones and rods work together in order to create the colour that is perceived. The psychological processes are related to the way each individual person perceives colour, and thus may be different to the next. Colour perception is different for everyone, something that is light blue to one person, may be light green to another person. Both the biological and psychological processes work together. A range of processes will be discussed throughout this essay and will demonstrate differences in the
