The two visual systems hypothesis talks about the processing of the visual information in two different routes in the brain (van Polanen & Davare‚ 2015). This idea was first introduced in 1982 when Leslie Ungerleider and Mortimer Mishkin described experiments that distinguished two streams that served different functions(Melvyn A. Goodale‚ 1998). They used the method know as ablation or also called lesioning. Using both recordings from neurons and ablation‚ they found that properties of the ventral

Sensation and Perception - Final Exam/Review Sheet 1. Identify by name the theory that investigates perception by presenting a stimulus signal in the presence of noise. What can we learn from the four possible categories of responses? 2. People are often described as being “nearsighted” or “farsighted.” To what actual conditions do these lay terms refer‚ and what why is it a problem? 3. Identify the visual defect that occurs when the course of the lightwaves entering your visual system are

Brian Kennedy and our text book both agree that visual literacy is a common language among everyone around the world. However the book go even further into saying that there has to be “visually literate person does not merely possess the capability of vision but goes on to mentally perceive and interpret the meanings of visuals.” (Avgerinou and Ericson‚ 1997)

CHAPTER 7 VISUAL AIDS Role of visuals Visual Aids are an essential feature of effective communication. Why? Let us answer the question with an example: Figure 78 Figure 7 is a visual aid that explains‚ in nutshell‚ some facts about the contributions each of the senses make towards helping people learn. An alternative to this visual would have been to present the information in a narrative form. This would require learners to read or listen to a text carefully‚ assimilate the facts and

Perception Essay After viewing the power point presentation and the videos provided‚ I learned about the relationship between representation and abstraction in art‚ context within art‚ contemporary art and finally about visual perception. Representation and abstraction was discussed in the video. In the discussion‚ representational art was compared to a lie or a falsehood. In the video‚ the commentators compared a representation painted by John Everett Millais called “Ophelia” (1851) and an abstract

How the perception of the blind or visually impaired differs from that of the sighted. Article 1: Auditory Substitution of Vision: Pattern Recognition by the Blind The goal of the experiment in this study was to investigate whether or not there was an effect on the performance of recognizing visual patterns using auditory substitution by the early blind. The reason for the study is because of the development of the graphical user interface (GUI) in information technology‚ relating to computer

Visual Perception Lab: Size Constancy Abstract This investigation is designed to illustrate the ability of the visual system to compensate for changes in retinal image size with viewing distance‚i.e the mechanism of size constancy. The accuracy of this mechanism will be evaluated under a number of different viewing conditions and thereby investigating the various cues for judging distance. Background ‘Size constancy’ is the perception of an object as having a fixed size‚ regardless of

Visual Sensory systems Visual sensory systems rely on electromagnetic (EM) waves to give an organism more information about its surroundings. This information could be regarding potential mates‚ dangers and sources of sustenance The human visual system involves communication between the eye and the brain to represent external stimuli as images. The human visual system gives the human body the ability to see our physical environment. The system requires communication between its major sensory organ

Visual technology undeniably has a central importance in the contemporary culture. It plays a phenomenally important role in enhancing our visual capability and helps us in perceiving myriad cultural beliefs in addition to guiding us when managing behavior‚ values‚ and social relationships. Visual culture is based on a wide range of mediums which serve as

Perception and the Perceptual Process The Perceptual Process The perceptual process is a sequence of steps that begins with the environment and leads to our perception of a stimulus and an action in response to the stimulus. This process is continual‚ but you do not spend a great deal of time thinking about the actual process that occurs when you perceive the many stimuli that surround you at any given moment. The process of transforming the light that falls on your retinas
