Secretory immunoglobulin A and cardiovascular activity during mental arithmetic: effects of task difficulty and task order.
Secretory immunoglobulin A (sIgA) in saliva and cardiovascular activity were measured at rest and during mental arithmetic. Task difficulty was manipulated by presenting easy, hard, and impossible versions of the mental arithmetic task in counterbalanced order, while task novelty was operationalised as order of presentation (i.e. first, second, third). Mental arithmetic elicited significant inc...
متن کاملPotential anti-androgenic activity of roxithromycin in skin.
Since acne formation is a multistep process accelerated by androgens, we examined whether a new anti-acne antibiotic roxithromycin (RXM) may act as anti-androgen using transient transfection assays in human skin fibroblasts. The result showed no significant effect of 0.5, 1 and 5 microg/ml RXM on 10(-9) M R1881-induced androgen receptor (AR) transcriptional activity. While the cotransfection of...
متن کاملAmbient temperature affects glabrous skin vasculature and sweating responses to mental task in humans.
We compared responses in heart rate (HR), mean blood pressure (MAP), sweating rate (SR), sweating expulsion (SwE), and skin vascular conductance (VC) to mental task among different ambient temperature (Ta) conditions, i.e., 12, 16, 20, and 24 degrees C. Seven subjects (27+/-5 yrs, 64+/-14 kg) underwent a 2-min color word conflict test (CWT) after 2 mins of baseline data acquisition following a ...
متن کاملAn EEG-based mental workload estimator trained on working memory task can work well under simulated multi-attribute task
Mental workload (MW)-based adaptive system has been found to be an effective approach to enhance the performance of human-machine interaction and to avoid human error caused by overload. However, MW estimated from the spontaneously generated electroencephalogram (EEG) was found to be task-specific. In existing studies, EEG-based MW classifier can work well under the task used to train the class...
متن کاملConstruction and Revision of Spatial Mental Models under High Task Demand
Individuals often revise their beliefs when confronted with contradicting evidence. Belief revision in the spatial domain can be regarded as variation of initially constructed spatial mental models. Construction and revision usually follow distinct cognitive principles. The present study examines whether principles of revisions which follow constructions under high task demands differ from prin...
