Navigational impairments have previously been reported in autism spectrum disorder (ASD). The present study examined the ability of individuals with ASD to generate and scan their mental image of a previously viewed map. Twenty-one ASD adults and 20 age-and IQ-matched comparison adults memorised a map of a fictitious island containing a number of landmarks. They then mentally imagined the map a...

Cognitive maps are widely used for representing decision makers' mental maps and their strategies. However, the cognitive map analysis is usually constrained into the static analyis and has difficulty in exploring dynamic nature of decision makers' mental map. In this paper, a simulation method of cognitve map in the discipline of system dynamics is developed and discussed. In this paper, the c...

BACKGROUND In an earlier study, our research group presented an alternative approach to measuring knowledge about mental disorders by constructing a structure-based expert model of the ICD-10 mental disorders. This article presents a validation of this expert model by measuring the emergence of such knowledge structures in psychotherapy students. SAMPLING AND METHODS The participants of a con...

This paper is presenting a short overview of a human factors project aiming to improve decision-making in navigation by removing the need to conduct mental rotations. This is done by presenting the map in an egocentric view, here called a 3D map. Laboratory experiments have shown clear advantages for the 3D map compared with traditional exocentric map displays. Finally a short description of on...

This study explored the effects of prior knowledge (high vs. low; HPK and LPK) and concept-map structure (hierarchical vs. network; HS and NS) on disorientation, cognitive load, and learning from non-linear documents on ‘‘the infection process of a retrograde virus (HIV)’’. Participants in the study were 24 adults. Overall subjective ratings of disorientation and cognitive load, as well as deta...

Imagery as Internalized Perception. The classic work on imagery has emphasized the similarity of images to percepts and of operations on images to perceptual or physical operations. Elegant experiments have supported this view: smaller imagined features take more time to verify, larger imagined distances take more time to scan, and figures displaced by greater angles take longer to mentally rot...
