Visual mental imagery is a complex process that may be influenced by the content of mental images. Neuropsychological evidence from patients with hemineglect suggests that in the imagery domain environments and objects may be represented separately and may be selectively affected by brain lesions. In the present study, we used functional magnetic resonance imaging (fMRI) to assess the possibili...

In this article we propose a method for cooperatively building a scene map between a human and a robot by using a spatial relational model employed by the robot to interpret human descriptions of the scene. The description will consist in a set of spatial relations between the objects in the scene. The scene map will contain the position of these objects. For this end we propose a model based o...

Expanding mental outlook for learners is one of the important open problems in e-Learning. Online should have the property of expanding and enhancing the mental outlook of learners in general and also, in particular, concerning the studied discipline. This paper presents an approach to this issue. The tool used for expanding the mental outlook is represented by concept maps. Concept maps are us...

Patients with neglect failure to detect, orient, or respond to stimuli from a spatially confined region, usually on their left side. Often, the presence of perceptual input increases left omissions, while sensory deprivation decreases them, possibly by removing attention-catching right-sided stimuli (Bartolomeo, 2007). However, such an influence of visual deprivation on representational neglect...

We present an algorithm for automatically laying out metro map style schematics using a force-directed approach, where we use a localized version of the standard spring embedder forces combined with an octilinear magnetic force. The two types of forces used during layout are naturally conflicting, and the existing method of simply combining these to generate a resultant force does not give sati...

How do we reason about incomplete spatio-temporal descriptions? How might a map influence formerly constructed preferred mental models? Little research so far focused on a combination of two central fields important for successful route planning: the way humans deal with constraint based reasoning (especially with some sort of spatio-temporal constraints) and the way in which humans plan with a...

In the human interpretation of cartographic maps the areas we shall call abstract regions consist of several symbols (map objects), which are grouped to a single object. This abstraction process is an important part of human map interpretation. Abstract regions exist as mental objects in a mental map in the interpreter’s mind. In this article we describe an approach to automate the human proces...

configural description or a mixture of the two, and rarely any other kind. These questions are not just an issue of academic interest. We have all often had frustrating experience trying to understand verbal directions a b u t how to get somewhere or trying to grasp the layout of an area by means of a map. Virtual reality is currently being proposed as having great potential for training people...

When describing known places from memory, patients with left spatial neglect may mention more right- than left-sided items, thus showing representational, or imaginal, neglect. This suggests that these patients cannot either build or explore left locations in visual mental imagery. However, in place description there is no guarantee that patients are really employing visual mental imagery abili...

New neurons are generated in the hippocampus each day and their survival is greatly enhanced through effortful learning (Shors, 2014). The numbers of cells produced can be increased by physical exercise (van Praag, Kempermann, & Gage, 1999). These findings inspired us to develop a clinical intervention for humans known as Mental and Physical Training, or MAP Training. Each session consists of 3...
