بررسی میزان همخوانی نتایج اندازه گیری خستگی ذهنی با مقیاس VAS) Visual Analog Scale) و دستگاه Flicker Fusion
Introduction: Mental fatigue is defined as body or soul tiredness which can be caused by stress, overwork, excessive use of drugs or physical or mental illnesses. Fatigue is one of the reasons of productivity loss as well as occurring accidents. Therefore, mental fatigue measurement is of great importance. This study was aimed to determine the consistency of mental fatigue measurement by s...
full textVisual analog scale (VAS) and nasal obstruction in persistent allergic rhinitis.
OBJECTIVE Nasal airflow resistance, as measured by rhinomanometry, is frequently impaired in allergic rhinitis (AR). However, rhinomanometry is scarcely available. The aim of this study was to verify the suitability of the use of visual analog scales (VAS) as a surrogate for rhinomanometry in quantifying nasal obstruction in patients with persistent allergic rhinitis. STUDY DESIGN Prospective...

Introduction: High mental workload is one of the important factors that results in errors in safety and occupational health scope and its measurement has high importance. So, this study aimed to determine validity and reliability of Verbal Online Subjective Opinion (VOSO) and Modified Cooper-Harper (MCH) scales in measuring mental workload. Methods: This study was conducted on 90 male studen...
full textVisual experience can substantially alter critical flicker fusion thresholds.
Studies of psychopharmacology often use the test of the critical flicker fusion (CFF) threshold as a measure of total information processing. It is true that studies of practice effects have shown that CFF thresholds are remarkably stable within and across multiple days of testing. This study confirms that subjects who undergo CFF testing on sequential days have stable thresholds, but also demo...

Three methods for perceptual rating of audio stimuli were compared. The Visual Analogue Scale, VAS, was implemented as two computer programs and compared to the VAS on paper. The first program is a straight-forward implementation, the second program introduces the Visual Sort and Rate method, VSR. VSR allows the subject to compare stimuli of similar rating to each other, thus making the orderin...
