Four dual-task experiments examined visuospatial, articulatory, and central executive working memory involvement during the development and application of spatial mental models. In Experiments 1 and 2 participants read route and survey spatial descriptions while undertaking one of four secondary tasks targeting working memory components. Converging evidence from map drawing and statement verifi...

To contribute to systems that reason about human attention, our work empirically demonstrates how a user’s mental workload changes during task execution. We conducted a study where users performed interactive, hierarchical tasks while mental workload was measured through the use of pupil size. Results show that (i) different types of subtasks impose different mental workload, (ii) workload decr...

Reasoning about the mental states of agents is important in various settings, and has been recognized as vital for teamwork. But the complexity of some of the more well-known agent logics that facilitate reasoning about mental states prohibits the use of these logics in practice. An alternative is to investigate fragments of these logics that have a lower complexity but are still expressive eno...

Cognitive maps refer to mental representations of maps or environments, as revealed in a variety of tasks. The simplest model of cognitive maps is that they are random degradations of real ones. Research using distance judgments, direction judgments, map recognition, map construction, and other information from memory for maps or environments suggests that distortions, rather than being random,...

There is significant current interest in decoding mental states from neuroimages. In this context kernel methods, e.g., support vector machines (SVM) are frequently adopted to learn statistical relations between patterns of brain activation and experimental conditions. In this paper we focus on visualization of such nonlinear kernel models. Specifically, we investigate the sensitivity map as a ...

Topographical orientation relies on the integrity of several cognitive functions and different strategies that individuals may adopt while navigating in the environment. Although previous studies have shown an age-related decline in navigational ability, these have not clarified the precise function or strategy that is affected. We hypothesized that aging may have an adverse effect on the abili...

Maps — specifically floor plans — are useful for a variety of tasks from arranging furniture to designating conceptual or functional spaces (e.g., kitchen, walkway). We present a simple algorithm for quickly laying a floor plan (or other conceptual map) onto a SLAM map, creating a oneto-one mapping between them. Our goal was to enable using a floor plan (or other hand-drawn or annotated map) in...

Abstract Translation is a process which needs concentration and a relaxed mind. Obsessive compulsive disorder (OCD) is a mental disorder which causes the patients to repeat something continuously so that it is done in the best way. As both translation and OCD are mental processes, this study has investigated the relation between these two mental processes. For this purpose, at first Oxford Plac...
