Differences between Spatial and Visual Mental Representations

چکیده
This article investigates the relationship between visual mental representations and spatial mental representations in human visuo-spatial processing. By comparing two common theories of visuo-spatial processing - mental model theory and the theory of mental imagery - we identified two open questions: (1) which representations are modality-specific, and (2) what is the role of the two representations in reasoning. Two experiments examining eye movements and preferences for under-specified problems were conducted to investigate these questions. We found that significant spontaneous eye movements along the processed spatial relations occurred only when a visual mental representation is employed, but not with a spatial mental representation. Furthermore, the preferences for the answers of the under-specified problems differed between the two mental representations. The results challenge assumptions made by mental model theory and the theory of mental imagery.

Saliency Cognition of Urban Monuments Based on Verbal Descriptions of Mental-Spatial Representations (Case Study: Urban Monuments in Qazvin)
Urban monuments encompass a wide range of architectural works either intentionally or unintentionally. These works are often salient due to their inherently explicit or hidden components and qualities in the urban context. Therefore, they affect the mental-spatial representations of the environment and make the city legible. However, the ambiguity of effective components often complicates their...
متن کاملReconstructing mental object representations: a machine vision approach to human visual recognition.
This paper introduces a new approach to assess visual representations underlying the recognition of objects. Human performance is modeled by CLARET, a machine learning and matching system, based on inductive logic programming and graph matching principles. The model is applied to data of a learning experiment addressing the role of prior experience in the ontogenesis of mental object representa...

Introduction: Mental retarded children who receive a wide range of health services, representing more than two percent of the population. Mental retardation is associated with significant constraints on mental performance and adaptive behavior as well as perceptual and practical skills. According to the studies, one of the important tools that can affect cognitive abilities, such as memory, is ...
متن کاملIndividual differences in the representations of novel environments
The present research investigated individual differences in representations of a novel environment. Thirty-eight participants traversed an unfamiliar route over two floors of a building and drew sketch-maps of the route. Participants also completed a mental rotation task and route knowledge tasks: orientation (pointing to nonvisible landmarks), landmark recognition, route tracing on a floor pla...
متن کاملTypes of Visual-Spatial Representations and Mathematical Problem Solving
Although visual-spatial representations are used extensively in mathematics and spatial ability is highly correlated with success in mathematics education, research to date has not demonstrated a clear relationship between use of visual-spatial representations and success in mathematical problem solving. The authors distinguished 2 types of visual-spatial representations: schematic representati...
