Behavioural evidence shows placebo modulations of motor performance. Different studies in this field supported that placebo improves sensible physical parameters such as force and speed. However, the effect of placebo on more complicated indices like harmony and symmetry of movement during gait has not been studied up to today. We explored if a placebo modulation of motor performance could affect...
This study investigated the behaviour of N1 peak towards perceived sound levels in different range of frequencies. Three sound levels as perceived as Talk, Loud and Shout were examined. In 10 subjects, the results showed that in all frequency ranges (4000 Hz, 1000 Hz and 500 Hz) the peak of N1 waves have significantly reduced when stimulated by Talk level as compared to Loud and Shout. Insignificant...
Protocol analysis is a rigorous methodology for eliciting verbal reports of thought sequences. The think-aloud protocol and the dialog-based protocol are two approaches for protocol analysis, in which the think-aloud protocol uses a single subject and the dialog-based protocol uses two subjects, who are verbally expressing their thoughts while completing the tasks. In this study, we evaluated and...
The experience of motion sickness in a virtual environment may be measured through pre and postexperiment self-reported questionnaires such as the Simulator Sickness Questionnaire (SSQ). Although research provides converging evidence that users of virtual environments can experience motion sickness, there have been no controlled studies to determine to what extent the user's subjective response is...
