Background and Purpose: Although the evolution of industrial systems toward digital technologies decreased the exposure to high levels of noise, it has created some problems encountered with low level and provoking noise (low frequency noise). In the present work, the mental performance of students exposed to low frequency and reference noises at low and high levels (45 & 65 dB) were studied....
Background & objectives: One of the factors affecting the performance of video display terminal users is their mental work load. Since low sleep quality causes fault and decreased accuracy in work, this study aimed to evaluate the relationship between mental work load and sleep quality in video display terminals users. Methods: This descriptive cross-sectional study was performed on 191 video d...
Introduction: One of the factors influencing the behavior and performance of nurses at the workplace is the mental workload. It is the amount of mental effort that a person uses during doing his or her task. Objective: The current study aimed at evaluating the mental workload and its related factors in the Intensive Care Unit (ICU) affiliated to medical and educational centers of Guilan Univer...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
When tested appropriately, infants appear to demonstrate false-belief understanding in the first year of life. Some have argued that this is inconsistent with the well-established relationship between social experience and preschoolers’ false-belief performance. We argue that these two sets of findings are not inconsistent because the ability to attribute false beliefs to others is necessary bu...
We investigated the role of body position on performance in four distinct types of mental imagery processing. Previous studies used the upright body position as standard procedure and therefore do not address the issue of whether mental imagery tasks are processed in accordance with ego-centered or gravitational coordinates. In the present study, the subjects were brought into one of three diff...
Functional MRI during performance of a validated mental rotation task was used to assess a neurobiological basis for sex differences in visuospatial processing. Between-sex group analysis demonstrated greater activity in women than in men in dorsalmedial prefrontal and other high-order heteromodal association cortices, suggesting women performed mental rotation in an effortful, "top-down" fashi...
An emotional stress arising as a result of intense mental arithmetic causes (in most subjects) an increase in blood flow through resting forearm muscle by an average of 85%. Combination of voluntary sustained handgrip contraction with mental arithmetic has shown that the duration of contraction increases by an average of 46%. This effect appears only in subjects who display an increase in blood...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
