Visual Processing

2020

Visual processing difficulties impact on reading and writing, and may also impact upon praxis. Weaknesses in visual memory can affect speed of visual processing, visual motor processing and attention. For students who have weaker visual processing skills, verbal instruction can aid the processing of

Reversible visual memory in transient splenial lesion A 19-year-old man presented with vertigo and headache. Diffusion MRI showed an increased signal on the center of the splenium. Neuropsychological assessment demonstrated impairment on immediate and delayed recall of the Rey-Osterrieth complex figure test. His visual memory had improved by the time the splenial lesion disappeared on follow-up MRI (figure). Although transient splenial lesions are commonly seen on diffusion-weighted imaging related with various conditions, the exact pathophysiology and its significance are not clear.1 Visual memory performance in our patient supports that splenium has an important role for integration of visual information through the temporal, parietal, and occipital cortical regions.2

<p>(a) Schematic of visual processing across several areas defined by anatomical structure and function of the area such as V1, V2, V4, and Inferior Temporal cortex (IT). The major input to the visual cortex is from the lateral geniculate nucleus (LGN) whose principal neurons receive input from the retina [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1011078#pcbi.1011078.ref026" target="_blank">26</a>]. (b) Models of the visual cortex. In feedforward models, information is only processed in one direction. In models with feedback connections, information from distant layers loops back to earlier layers (e.g. from IT to V1) across multiple distances [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1011078#pcbi.1011078.ref027" target="_blank">27</a>]. Also, local activity feeds back to the same layer. (c) Feedforward models map each point in the input space to a point in the output space. In a model with feedback, a static point in the input space can generate a temporal dynamic (or trajectory) in the output space. The properties of the trajectory strongly depend on the feedback connections and the input.

Processing Visual Communication

In the era of 4.0, which marked by the outbreak of COVID-19, many people took new steps creatively with an orientation to economic value. This seems potentially important to support the sustainability of national development, which is commonly known as development with an economic emphasis on cultural insight. This paper aims at the overview of the phenomenon in creating Balinese art illustrations through digital technology. In this case, it seems that digital technology really helps art activities as can be seen on the difference between manual and digital art activities. It also shows that digital technology-based art products can be obtained through a production process that relies on ideas and knowledge related to the created product. Thus, production can be carried more faster with superior quality products, both totally new products and reproduction products. In addition, with digital technology, marketing of production results can be wider, faster, practical and smoother in the pandemic era. In fact, the product turn out have significant economic value during the COVID-19 pandemic. This phenomenon highlighted by referring to the theory of globalism with market ideology nuances. Based on this theory, there is a tendency that with creative visual communication design of economic nuances would result in products that are quite saleable via online market, not only in Bali but throughout Indonesia and even abroad. Therefore, this phenomenon shows the important contribution of creative economy towards sustainable development.

Unconscious Visual Processing

Khalid, Shah · osnaDocs (Osnabrück University) · 2013

Visual information can be processed by humans both consciously and unconsciously. Under conscious conditions the humans are aware of the input, and thus can process it according to their goals. However in unconscious conditions participants remain unaware of the input, as evident from their chance accuracy when judging about the input. It has been shown that although participants may not consciously perceive subliminal input, the input can be processed automatically. Masked priming is an experimental paradigm to investigate unconscious visual processing. In this paradigm the input is presented for a very brief duration, often temporally sandwiched between a pre- and a post-mask. In this thesis, I and we mostly applied the masked-priming paradigm to study human unconscious visual processing using words and face images as input. We conducted five studies to understand unconscious visual processing and compare it with conscious processing. Our first study is about the accurate measurement of the visibility of subliminally presented visual input. In the second study, we provide a test-case for the embodied cognition theory using subliminal words. The third study is concerned with conflict control under aware and unaware conditions. In our fourth study, we tried to understand the role of subcortical structures in subliminal face processing. The fifth study is concerned with relations between space and valence priming effects. Together our findings further the understanding of unconscious and conscious visual processing.

<p>Visual processing is conducted at many different levels in a hierarchical manner. Light strikes the retina and is converted into electrical signals. They are then sent to the lateral geniculate nucleus (LGN) in the subcortex and further projected onto the primary visual cortex (V1), where primitive features including orientation and spatial frequency (coarseness) in the signals are processed highly locally. The signals are further sent to higher cortical areas. At a higher level, more abstract and complex features tend to be processed more globally. Spatial/motion visual signals are predominantly processed in the parietal areas and shape/object signals are predominantly processed in the temporal areas. Then the signals are used for decision making in parietal and prefrontal areas. However, the hierarchical processing from lower to higher areas (black arrows) is just one aspect of visual information processing. First, signals also flow from higher to lower areas (red arrows). For example, attention that may originate at prefrontal and/or parietal areas exerts top-down signals to low-level visual areas. Second, within the same visual area spatially remote regions can interact with each other, following initial local processing.</p>

Abstract This entry begins with the parallel visual pathways in the brain that provide the basis for the major pieces of a mediated message: who, what, where, when, and how. Next are the attention and memory mechanisms that give rise to a mental representation of the message, followed by research on the impacts of dual modes of processing, message complexity, and multitasking on memory for and comprehension of the messages. Finally, the argument is made that new methods are needed to understand the comprehension of mediated messages, especially stories, across time.
