When looking at the video of the bouncing balls, the first step of the perceptual process begins when the balls (also in this case referred to as the distal stimuli) reach receptors in the eye. The "ball" the individual is observing is the distal stimuli because it is the object in the environment being sensed. The light from the balls on the screen then get reflected and reach the visual preceptors. This is step 2 of the visual processes and can be considered the Principle of Transformation. This principle states that stimuli and responses created by stimuli are transformed or changed between the distal stimulus and perception. When the light reflected enters the eye, it is transformed as it is focused by the eye's optical system. At this stage the light is focused by the cornea and the lens which respectively make up the front of the eye: the cornea in front and the lens directly behind it. At this point of the process the optics of the eye form a sharp image of the balls on the receptors of our retina. This image of the balls that we now see is considered the proximal stimulus due to its position in reference to the receptors. The individual is now able to see the "image" of the balls, and if all optics are working correctly this will be a clear crisp

2.Accommodation: the process by which the eye's lens changes shape to focus near or far images on the retina.

One frame from each camera is pulled into the program and then rectified based on calibration of each camera. The calibration process takes in the camera calibration parameters of the cameras, the rotation, and translation of the second camera in relation to the first camera. After being rectified based on the calibration, a disparity map is created. A disparity map is an intensity map that shows the measurements of

The next nearest star in our Milky Way Galaxy is Alpha Centauri. It is about 41,000,000,000,000 km. Using the scale from Procedure B, calculate how far Alpha Centauri would be on our scale. Show your work!

The sum of

Binocular rivalry is a term used for the switching of perception between two different images that are simultaneously seen by the eyes. When this occurs, you are only conscious of one of these images at a time, with the dominant image switching between the two every few seconds. During binocular rivalry, either all or part of one of the images is suppressed from consciousness. There are three main properties of binocular rivalry; exclusivity, inevitability and stochasticity. Exclusivity means that only one image can be seen at a time, inevitability is that perception will always change at some point, as it is impossible to hold onto one image forever, and stochasticity is that switching will occur at unpredictable times (Fox and Herrmann, 1967). Many factors can influence the dominance of an image, including motion, contrast and salience.

Next, refraction was studied. This was accomplished by noting the placement of a prism, and then putting down place markers. Then, while one looked through the prism, additional place markers we put down that appeared to line up

Soon the photograph doubled. An almost exact copy, but with a single difference that could have been easily missed if one was not careful. His body raised over the table a few inches higher. His angle, was now only slight.

Viewing this from an oblique angle, there is perspective in the sense that objects which are horizontally far away are seen smaller, like viewing a large photograph, not quite like a 3D view.

Vernier acuity is the capability to identify tiny spatial offsets in paired lines, dots, or objects.

a. (SSSSP 1) For example, if you look at a clock the numbers might be all mixed up. When you look back the numbers will change again.

The Sherif (1936), asked his subjects to seat themselves in a darkened room where they were to observe a pinpoint of light located at some distance from them. The subject was to report when the light started to motivate and to indicate how far it had moved. In actuality, the light never moved at all, but there was an almost universal trend to perceive movement, a phenomenon that is termed the auto kinetic When Sherif asked the subjects to report how far the light had moved, he found, or a series of one hundred exposures, that each person tended to resolve down to a narrow range of estimates however three to four inches,
