Navigation through an environment is a fundamental human activity. Although group differences in navigational ability are documented (e.g., gender), little is known about traits that predict these abilities. Apart from a well-established link between mental rotational abilities and navigational learning abilities, recent studies point to an influence of trait anxiety on the formation of interna...

In interactive layout a drawing is repeatedly modified either by the user or by the assistance system. A usability requirement states that the assistance system should alter the layout such that the user’s mental map is preserved. This work concretises mental map preservation from a cognitive science perspective. A notion of similarity that is based on the idea of transforming spatial mental mo...

Sympathetic neural responses to mental stress are well documented but controversial, whereas sympathetic neural responses to emotional stress are unknown. The purpose of this study was to investigate neural and cardiovascular responses to emotional stress evoked by negative pictures and reexamine the relationship between muscle sympathetic nerve activity (MSNA) and perceived stress. Mean arteri...

The article demonstrates the inadequacy in the traditional approach of psychology to the description of products of mental representation of perception. The principles of objective representation of subjective experience (principles of “mental map” construction) contain a whole range of contradictions. We propose a consistent mathematical description of the “mental map” based on psychosemiotic ...

Mental stress consistently increases arterial blood pressure, but this reliable pressor response is often associated with highly variable muscle sympathetic nerve activity (MSNA) responsiveness between individuals. Although MSNA has been shown to be reproducible within individuals at rest and during the cold pressor test (CPT), intraindividual reproducibility of MSNA responsiveness to mental st...

BACKGROUND Australian General Practitioners have been beneficiaries of extensive training in mental health care delivery over the last few years but less so other workers who support those with mental illness. Training is needed as it is widely recognised that the most effective interventions to prevent and treat mental disorders are often not readily available. The Mental Health Aptitudes into...

OBJECTIVE To study vascular reactivity according to the analysis of blood flow and peripheral vascular resistance at rest and during mental stress in pregnant women with mitral stenosis. METHODS Twenty two women with mitral stenosis, 13 of whom were pregnant (PS) and 9 were non-pregnant (MIS), and 9 healthy pregnant women (NP) were studied. During gestation, 9 out of the 13 patients of the PS...
