The effect of office sound on performance has recently become the topic of much disagreement. Several studies have attempted to measure the effect of sound on office performance, but no consensus has been attained. Studies have tried to check the effect of ambient noise on degrees of alertness and fatigue, but the results are combined. A number of researchers report that the outcomes are consistent across a large number of classes, but decisions are frequently controversial. A unique laboratory evaluation (EQ-i) was designed for the experimental assessment of office noise. The test has proven to be a trusted instrument for measuring the impact of sound on office productivity.
The EQ-i relies on two components. 1 component measures the cognitive processing of workplace employees, while the other element measures the subjective reaction of office workers to different visual stimuli. The testing process is carried out in a quiet area with the noise of a personal computer turned away. A battery of tests is performed on a specific group of office employees. A subjective questionnaire can be carried out on each person to obtain information in their working habits and feelings about the office environment. Following a series of tests are performed on a random sample of workplace employees, a mean total score is calculated for each person.
Several other explanations have been advanced to account for the outcomes of the EQ-i results. Possible explanations are that office employees weren't subjected to enough substantial intensity or low intensity noise throughout the testing interval, office equipment was inaccurate, or the results were skewed due to several confounding factors. No alternative explanation has yet to be offered that can clarify the results obtained from this test.
An evaluation study was conducted to determine the association between ambient temperature and indoor lighting at a medical setting. Researchers measured indoor lighting at four different points in the office space and found a strong and significant relationship between the two. The researchers attributed this relationship to the effect of light on worker's moods. Indoor temperature was shown to be negatively associated with the mood of office workers as evidenced by a statistically significant increase in stress levels. The authors concluded that"the present review... suggests that there is a negative relationship between ambient temperature and disposition among office employees."
In a different study, researchers examined the effect of red vs. blue light on neurobehavioral testing. They quantified neurobehavioral testing in a dimly-lit area and found no real difference in functionality between conditions. However, the researchers stressed the importance of using an proper neurobehavioral testing protocol and performing standardized psychological tests in clinical settings. They also emphasized that more studies must be done in order to examine the impact of low illumination on neurobehavioral testing.
A third research project tried to assess the impact of temperature on reaction time in a laboratory setting. Researchers measured reaction time at a dimly-lit room and found that the response time increased when there was an increase in room temperature. However, they stressed that this wasn't a substantial impact and has been influenced by the existence of other aspects. For example, a small increase in temperature diminished the amount of beta activity. What's more, the researchers emphasized that the impact of temperature on the reaction time could have significant implications for executive function evaluation.
The fourth study project analyzed the effect of temperature on executive function in an environment with two distinct light-sensitivity levels (daytime or dark). Two office workers, one with a day/night preference and the other using a no-light taste, participated in a job where their performance was tested with a reaction time paradigm. After completing the job, the operation of the two office employees was compared. The results demonstrated a substantial main effect of temperature on the response time (p = 0.049). The authors concluded,"A distinct window of temperature advantage may donate to executive processing rate ." This study showed that fever did really have a favorable impact on reaction time as it had been commanded for ambient lightness or darkness.
Overall, these studies confirm the importance of fever for function performance. Specifically, they show that temperature can modulate numerous aspects of performance such as attention, mood, alertness, and psychological functioning. Office employees are particularly prone to temperature fluctuations, which is likely because of the inherently challenging nature of the job that involves sitting in front of a computer screen or working with intense lighting conditions.
