In rational manner, visual memory can be defined as any memory for which the stored information was acquired by the visual system. However, such a definition is too broad. Thus visual memory encompasses memory representations that maintain information about the perceptual properties of viewed stimuli, but the format in which that information is encoded can vary from low level imagistic representations generated in early visual areas to higher level visual representations stored and abstracted away from the precise spatial structure of early vision.
The Visual Information Analysis (Todd 1999) incorporates areas related to the cognitive skills used for receiving and organizing visual information from the surrounding environment. The visual information

Compared with iconic memory representations, VSTM representations are longer lasting, more abstract, and more durable. VSTM representations can survive eye movements, eye blinks, and other visual interruptions, and they may play an important role in maintaining continuity across these interruptions. VSTM is usually considered to be the visual storage component of the broader working memory system. VSTM is thought to be the visual component of the working memory system, and as such it is used as a buffer for temporary information storage during the process of naturally occurring tasks. The role of VSTM in bridging the sensory gaps caused by saccadic eye movements. These sudden shifts of gaze typically occur 2-4 times per second, and vision is briefly suppressed while the eyes are moving. Thus, the visual input consists of a series of spatially shifted snapshots of the overall scene, separated by brief gaps. Over time, a rich and detailed long-term memory representation is constructed from these brief glimpses of the input (Hollingworth, 2004), and VSTM is thought to bridge the gaps between these glimpses (Irwin, 1991) and to allow the relevant portions of one glimpse to be aligned with the relevant portions of the next glimpse (Currie, McConkie, Carlson-Radvansky, & Irwin, 2000; Henderson & Hollingworth,

Processing capacity is a very broad and flexible category according to many researchers. In fact, the quote above mentioned suggests that we often fail to notice things that happen just in front of us (unexpected events that are often salient) either because we were completely absorbed by something else or because we had so many things to do at the same time that we couldn’t pay attention to it. We have all at least once failed to see a friend who was waving at us while eating in the cafeteria or walking in a crowded street. The primary question that we should ask ourselves is: how many things can we attend at the same time? The truth is that we didn’t perceive this friend because of a phenomenon called “inattentional blindness”. The problem is that the richness of our visual experience leads us to believe that our visual representation will include and preserve the same amount of detail (Levin et al 2000). In this paper we’ll see the different theories of inattentional blindness, and the classical theories demonstrating this paradigm.

Mcleod (2007) defines memory as the structures and procedures included in the storage and later retrieval of information. Evidence hints that the predominant coding technique in short term memory (STM) is acoustic coding. The principle encoding system in long term memory (LTM) seems to be semantic coding (by meaning). However, information in LTM can also be coded both visually and sound-related (Mcleod, 2007).
The first stage of memory is the sensory memory. Sensory memory holds sights, sounds, smells, textures, and other sensory impressions for only a few seconds, and it operates on an unconscious level. (Zimbardo, P., & Johnson, R. (2013). Memory. In Psychology: Core Concepts With Dsm-5 Update (pp. 177-179). Pearson College Div.)This stage of memory is the shortest element of memory. Sensory memory has the ability to retain impressions of different sensory information. Sensory memory is the ultra-short term memory and it retains brief impressions of the sensory stimuli after the stimulus has ended. It holds the shortest impression of sensory information and even when the sensory system does not send information the sensory memory still holds the shortest impression. There are many different issues and characteristics of the sensory memory; it has a high capacity to form memory registration of visual data, and the information that’s stored is un-interpreted, and the it the visual information fades away after less than a second. In order to use the information in your sensory memory, you must encode the information quickly. The sensory memory is the hardest memory to grasp and most of what we sense is forgotten. Sensory memory allows the eye to have a larger field of vision by remembering images that your eye has already focused on. The sensory memory, in general, allows us to maintain incoming sensory information long enough for us to screen it and determine if it is important. (Zimbardo, P., & Johnson, R. (2013). Memory. In Psychology: Core Concepts With Dsm-5 Update (pp. 177-179). Pearson College Div.)
Memory is a group of related mental processes that are involved in acquiring, storing, and retrieving information (Hockenberry and Hocenberry page 232). I will be addressing two specific types of memory: short-term memory and long-term memory. Short-term memory holds temporary information transferred from sensory memory or long-term memory. Sensory memory is the first stage of memory and obtains information for a brief amount of time. Short-term memory is also called active memory and is stored in the prefrontal cortex which is the most active part of the brain during an activity. Short-term memory can hold information for roughly twenty seconds, but sensory memory holds information for a shorter amount of time. We usually store things such

Making and storing memories is a complex process involving many regions of the brain. (3). Most experts agree that we have two stages of memories - short-term memory and long-term memory. Short-term memory is the immediate memory we have when we first hear or perceive someth...

Memory has been and always will be associated with images. As early as 1896, leading psychologists were arguing that memory was nothing more than a continuous exchange of images. (Bergson) Later models of memory describe it as more of an image text; a combination of space and time, and image and word. (Yates) Although image certainly is not the only component of memory, it is undoubtedly an integral and essential part of memory’s composition.
Long-term memory is how humans process in the present, recall information from the past, or think about the future. Without long-term memory one cannot remember past memories, today, or what we may plan to do in the future. On top of that, there is no learning without long-term memory and the progress that we see today in our fast pace driven world would not exist. This is why the study and understanding of long-term memory is important for further knowledge of human nature. The long-term memory itself takes in many different forms of information including images, sounds, and meaning. The orientation of memory encompasses three important stages and the first is encoding. Encoding takes places in different locations inside the brain and this

Normally sighted people think of visual literacy as the way in which we interpret and decode meaning in advertising, signage, art, and so on. What this course in visual literacy has taught me, is that the term “Visual Literacy” can be altered depending on the persons individual sense of vision. James Elkins comes the closest to the best description of visual literacy, “Understanding how people perceive objects. Interpret what they see and what they learn from them.”
Prior knowledge plays a pivotal role in every aspect of human life. Knowledge can be stored in various formats like images, features, statistical patterns, all these formats help in making sense of the environment. Using prior knowledge humans can perform various activities including, but not limited to: focusing attention, organizing information in to groups, categorizing objects around, hypothesizing, understanding language, and generating inferences(Smith & Kosslyn, 2007). Processing of information is influenced by prior knowledge during the top down processing. Once signal has been detected by the biological visual system, we try to infer meaning using the prior related knowledge which has been stored in the long term memory based on category, association and similarity in features and statistical patterns(Wickens, Lee, Liu, & Becker, 2004). Prior knowledge has no boundaries and it keeps on changing based on experience with the environment making it easier for us humans to understand our surrounding better and quicker as time passes.
