Allan Paivio's dual-coding theory is a basis of picture superiority effect. Paivio claims that pictures have advantages over words with regards to coding and retrieval of stored memory because pictures are coded more easily and can be retrieved from symbolic mode, while the dual coding process using words is more difficult for both coding and retrieval.
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
Patients with brain damage that impairs perception in specific ways, for example by damaging shape or color representations, seem to generally to have impaired mental imagery in similar ways. [61] Studies of brain function in normal human brains support this same conclusion, showing activity in the brain’s visual areas while subjects imagined ...
Eidetic memory (photographic memory) may co-occur in visual thinkers as much as in any type of thinking style as it is a memory function associated with having vision rather than a thinking style. [ citation needed ] Eidetic memory can still occur in those with visual agnosia , who, unlike visual thinkers, may be limited in the use of ...
The brain encodes multiple inputs such as words and pictures to integrate and create a larger conceptual idea by using amodal views (also known as amodal perception). Instead of being representations in modality-specific systems, semantic memory representations had previously been viewed as redescriptions of modality-specific states.
An example of a colored geometrical pattern a subject would encode, store, and recall while performing a visual memory neuroimaging test. Neuroimaging studies focus on the neural networks involved in visual memory using methods designed to activate brain areas involved in encoding, storage, and recall.
The brain activity is tied to one thing, like a specific object or task. The goal is to figure out how the brain represents specific things (like seeing a face or recognizing a word) when you're actively engaging with something. For example, with fMRI scans, researchers can track brain activity while people look at different objects or images.
In a way, art externalizes the functions of abstraction in the brain. The process of abstraction is unknown to cognitive neurobiology . However, Zeki proposes an interesting question of whether there is a significant difference in the pattern of brain activity when viewing abstract art as opposed to representational art.
