We suggest that mental depictions create a bridge between imagery and mental model research by positing the referent as the primary conceptual entity The analog/propositional debate concerns the nature of imagery itself (to put it very crudely, the analog side thinks mental images are inner pictures, and the propositional side think they are inner descriptions), whereas the dual/common coding debate concerns the functional role played by imagery in the cognitive processes of memory and thought Since the later 1980s Kosslyn has been more concerned with the neuroscience of mental imagery than with the computational model that was central to his earlier work, but there is no reason to think that this has made his theory any more analog, and, in fact, he rarely uses the term. 28

Strong evidence for analog theory is seen when the temporal and other relationships characterizing the inspection of a visual stimulus is the same as that found when reporting on a visual image. The literature on the characteristics of visual images provides an abundanc whether recent neuroscience evidence clarifies the debate over the nature of mental images. I claim that when such questions as whether images are depictive or spatial are formulated more clearly, the evidence does not provide support for the picture-theory over a symbol-structure theory of mental imagery As neither picture theory nor PA theory assimilates imagery to linguistic/conceptual representation, both may appeal to dual coding theory in this regard. Mental scanning is readily explained by PA theory's claim that imagery consists in covertly going through the motions of the equivalent perceptual process

This study critically reviews a number of these arguments as they pertain to three different types of mental representation: perceptual representations, imagery representations. of certain mental imagery tasks is shown to depend on which of the alternative structural descriptions of an object is used, and this is interpreted as evidence that structural descriptions are an important component of mental images.

The Relation Between Mental Imagery and Perception. The central issue in the neuropsychology of mental imagery, and the issue most relevant to the topic of this volume, is the relation between imagery and perception. This issue has a long history of controversy within cognitive psychology The past 25 years have seen a rapid growth of knowledge about brain mechanisms involved in visual mental imagery. These advances have largely been made independently of the long history of philosophical - and even psychological - reckoning with imagery and its parent concept 'imagination'. We suggest that the view from these empirical findings can be widened by an appreciation of. The mental imagery tasks reported here are different, and the emphasis is on showing the differential effects of alternative structural descriptions for the same object. However, the conclusion is the same: that mental imagery involves the manipula- tion of structural descriptions

The analog/propositional debate concerns the nature of imagery itself (to put it very crudely, the analog side thinks mental images are inner pictures, and the propositional side think they are inner descriptions), whereas the dual/common coding debate concerns the functional role played by imagery in the cognitive preferendal use of pictorial operations (e.g: scanning) on mental imagery and to account for this they ascribe to this representation certain properties that are usually associated with pictures. Such operations have a special status in analog representational theories, but not in propositional theories

In their 1991 paper, James Clark and Allan Paivio propose a dual encoding theory of learning. The main takeaway from this is that including imagery with verbal codes allows for elaborated or deeper processing to take place (Levels of Processing Theory), creating multiple pathways to recall the information in the future Over the past 50 years, philosophers and psychologists have perennially argued for the existence of analog mental representations of one type or another. This study critically reviews a number of these arguments as they pertain to three different types of mental representation: perceptual representations, imagery representations, and numerosity. In a recent article, Anderson argued that behavioral data could not distinguish alternative theories of memory representations. The theorem Anderson proved does not support his conclusions. Five fallacies in his argument are criticized: (1) behavior.. of imagery and language. Imagery is fundamental to the process of thinking with numbers.

Visualization is a very common technique used in hypnotherapy and NLP. It involves creating mental images or pictures in a persons mind. Visualization is an experience that, on most occasions, significantly resembles the actual experience of perceiving some object, event, or scene in the physical world, yet is not actually present to the senses. Visualization [ Mental images are one of the more obvious aspects of human conscious experience. Familiar idioms such as the mind's eye reflect the high status of the image in metacognition. Theoretically, a defining characteristic of mental images is that they can be analog representations

Some form of a mental representation was the only plausible conclusion for cognitive theorists to explain the results of their imagery experiments. As a result, they evolved theories of the functional and computational mechanisms associated with mental imagery [4] Recent studies have provided evidence for mental simulation as a strategy in mechanical reasoning. This type of reasoning can be dissociated from reasoning based on descriptive knowledge in that it depends on different abilities and memory stores, is expressed more easily in gesture than in language, exhibits analog properties, and can result in correct inferences in situations where people do.

But the explanatory purchase pictorial representations afford here has seemed to stem from their representing shapes and orientations holistically, like a photograph.

The propositional representation is the relationship that can be represented by abstract symbols (Goldstein, 2011). It explains what a picture looks like or features that stick out that are easy to remember. The spatial representation is when different parts of an image can be described as corresponding to specific locations in space (Goldstein. Perhaps the most frequently posited example of neuroscience constraining psychological theory is the debate over the representation of mental imagery -- whether images are represented in propositional or analog form

The alter­native view of imagery posits that mental images are represented as abstract propositions. According to this account, mental images, language, and other infor­mation relies on one primitive code that the brain uses to process all types of information (i.e., The Language of Thought, Fodor, 1975) Mental imagery is the ability of humans to remember, recollect, traverse, and make judgements. Also, mental imagery is effective in analyzing and treating many mental health disorders. It is a collective term referring to illustrations and the associated understanding of sensory information without a direct external stimulus mental simulation is based on internal spatial represen-tations of mechanical systems (see Box 1), involves analog imagery, and can be dissociated from reasoning based on descriptive representations or explicit knowledge.
