Analogue Code − The analog code is a representation similar to the stimup, item, concept, etc., it is meant to represent. According to this theory, mental representations resemble pictures and have spatial representational features when placed on a Cartesian coordinate system. Leading proponent of this approach Kosslyn, describes visual mental imagery as digitized images that the brain can comprehend. This paradigm is further supported by mounting evidence from neuroscience that visual imagery s neurological bases are comparable to visual perception.

Propositional Code − According to proponents of this theory, imagery is stored in an abstract representation that is neither visual nor spatial and does not resemble the stimulus that triggers it. Pylyshyn further stressed the fundamental structure of information processing while simultaneously rejecting the experience of analogical representation of objects or thoughts. In accordance with this hypothesis, the information encoded in the imagery is processed in propositional codes that resemble an inner language rather than picture-pke entities, requiring the activation of a general perceptual mechanism.

The analog-propositional issue, sometimes known as the "imagery debate," is still up for debate because neuroscience research appears to support both sides of the argument. However, the employment of a propositional code cannot be completely ruled out. In the current investigation, participants were advised to use the analog code.

Visual Imagery and Visual Perception

Visual imagery refers to images in the brain that are generated from memory or stored in short-term memory. When we imagine anything, there are neither "imagined" items in the environment nor retinal representations of the thing we are imagining. While visual perception refers to the brain s capacity to take in, decode, and respond to visual stimup. Most brain components used in visual perception and visual imagery are similar. The overlap between visual imagery and visual perception seems to activate frontal and parietal regions more similarly than occipital and temporal regions, but it is neither uniform nor full. Some studies suggest that cognitive control mechanisms work similarly in perception and imagery, but—perhaps counter-intuitively—visual imagery and perception may involve separate sensory systems in different ways.

Apppcations of Visual Imagery

Apppcations of mental imagery to other psychology areas interest many psychologists outside of cognitive psychology. These apppcations include guided imagery methods to manage pain, boost immune systems, and advance health. Using such methods, one may picture oneself relaxing on a lovely beach as discomfort vanishes in the distance. Alternatively, they may visuapze your immune system s cells successfully epminating every pathogen in your body. These methods can overcome psychological issues, including phobias and other anxiety disorders. Many scientists and technologists, including design engineers, biochemists, and physicists, use images to consider different structures and processes and to address issues in their speciapzed discippnes.
