Psychomotor Vigilance Task (RTTT)

867 Words4 Pages

Volunteers were screened by telephone. After screening, the eligible participants and the general practitioner received a medical questionnaire for the verification of the drug usage. Once enrolled in the study, the subjects attended a training day to familiarize them with the experimental procedures. The actual testing day was one week later and included the tests Risk Taking Test Traffic (RTTT), Trailmaking A and B (TMT-A and TMT-B), Digit Symbol Substitution Task (DSST), Reaction test (RT 1,2 and 3), Determination Test (DT) and Psychomotor vigilance task(PVT). Participant’s sleep complaints were evaluated using Dutch versions of the Pittsburgh Sleep Quality Index (PSQI) (Buysse et al. 1989) and the Groningen Sleep Quality Scale (GSQS) …show more content…

24 different traffic situations were displayed to the subjects. The participants were asked to push a button at the moment they would not execute the task of the situation anymore because it became too dangerous. (Hergovich, Arendasy, Sommer, & Bognar, 2007). Trailmaking A and B (TR A and TR B) The TMT is a pen-on-paper test which provide information about selective- and divided attention and executive functions. The test consists of two parts. In part A the participant was instructed to connect 25 numbers as soon as possible in sequential order by drawing a line. Part B should be carried out in the same way as part A. The only difference is that the targets of part B are not only numbers but also letters and should have to be connected in the following way: 1-A-2-B-3-C etc. The primary outcomes of both parts are the time that a participant needed to complete the task and the number of …show more content…

The test measures a combination of stress tolerance, divided attention, mental flexibility and reaction time. This was done by providing the participant a number of stimuli on which they had to react in different ways. These stimuli consisted of colored spots, auditory signals and foot signals. The speed of the test presenting stimuli was adapted to the reaction time of the participant. Stress was caused by providing stimuli in which the participant can’t give optimal response. The primary outcome is the median reaction time and correct responses. The duration of the test is approximately 4 minutes. Psychomotor vigilance task (PVT) The PVT (Dinges and Powell 1985) is based on a visual RT test. The visual stimulus was a counter which turned on at random intervals between 2 and 10 seconds. The subject was required to respond by pressing a button when the counter turned on. In response to the subject’s button press, the counter display stopped. The main performance parameters that are used are the reaction time and number of lapses (= Response Time ≥500 msec). The test duration is 10

Injuries in the places where you will be measuring will affect the reaction time for example if you have a knee injury such as Patellofemoral Pain Syndrome that will affect the reaction time because the test in conducted near the patella and you may have no reaction or slow reaction due to pain or bone rubbing. Some other factors are that for a voluntary reaction it takes longer for the brain to process the information and act upon it. If there is a distraction, then the reaction time would be slower and another impact would be that if there is an interception by other things or other electronic devices they may interfere with the

What I mean by that is, as excepted with an increase in secondary task in condition four my average was the highest meaning it took me the longest because my attentional demands had changed. A result I was not excepting was getting the same average for condition one and three. As stated earlier my trails in condition three were all over the place. It would be interesting to redo condition three and see if my times would still be all over the place or would be different. Also, comparing condition three results with the other students in my class and see if they had a similar experience.

This empirical, quantitative study examined the effectiveness of the Sleepwise intervention program which is a parent-assisted group-based treatment for sleep disturbance which was recently adapted for older children and adolescents with developmental disabilities. Twenty-six families with children aged 8–17 years participated. The study compared a treatment and a wait-list control group at baseline, post-treatment and 2 months post-treatment on measures of child and parent functioning. Results demonstrated that the Sleepwise approach was effective in reducing sleep disturbance and parent stress. Sleepwise is a manualized intervention which involves educational workshops for parents, and employs behavioral, sensory and communicative strategies.

My science fair are all about the reaction time of video gamers. I’ve gathered all the research on reaction I would like the average is usually 150-250 is the average. Some good games for reaction time are 1st person shooters and fast paced games. Ry-them games are also good for reaction time. The reflexes are what I’m testing discovered by a German in 1875.

Although the accuracy was part of the measurement, the data analyzed only includes reaction time. Therefore, the similar average reaction time between male and female could be due to the difference in accuracy. For example, fast reaction time could have easily been achieved by continuously pressing the same response for every trail. Consequently, the reaction time would be as fast, but the accuracy would be very low. However the finding will not have reflected this important factor.

Finally, in a Lag 3, the participants were required to avoid the previous three sequences. The participants were tested for 200 trials that lasted between 20-30 minutes, however at the end of 50 trials, or after each lag, the participants were advised to record their ideas about earning points. The results of the experiment showed that college students averaged more responses per minute than the older adults, F(1, 20) = 47.2; p < .05. Lopatto et al. (1998) conclude that the response variability contingency shaped variable responding.

Introduction Good morning everyone. I’m Nur Atiqah binti maznan and today I will deliver a speech title ‘People should care more about sleep’ Most of us in this class will say that we not get enough sleep because of all assignments, lab reports and so on like just now. So, we called this situation as sleep deprivation which means a condition where people not get enough sleep. We are in the same shoes, so no worries. A research from Brown University stated that, from a survey they conducted to a group of college student, 11% student have a good sleep but the rest which is 73% from the same study were found to have a sleep problem.

In the viewpoint of perceptual load theory, stimulus differences happen when the stimulus has high or low perceptual load. The perceptual load discusses complications of the physical stimuli, especially the distractor stimuli, for example, a right-angled symbol surrounded by a rounded symbol is when there is a perceptual load which is low and when there is a right-angled symbol enclosed by heaps of dissimilar symbols this is high perceptual load. Because of the supposed inadequate volume of noticeable materials, in high perceptual loaded studies the aim of noticeable materials is worn out earlier thus enabling to react to the goal quicker in contrast to a lower loaded perceptual

The number of digits in the memory set varies from one to six. In the search phase, the participant is given a succession of randomly selected single digit probes. In each trial, the participant has to decide as quickly as possible whether a probe belongs to the memory set (i.e., positive probe) or not (i.e., negative probe). Van Gerven et.al (2004) results suggest the reaction times of the elderly participants increased more as a function of memory load than the reaction times of the young participants. As well for pupillary response the young participants had greater pupil dilation than older participant when there was an increase in memory load (set size).

It can be caused by disorders such as obstructive sleep apnea (OSA), narcolepsy, and idiopathic hypersomnia [1-4]. A previous study showed that the prevalence of EDS was 2.5% in the Japanese general population [5], and another study showed an EDS prevalence of 8.7% in the general population of the United States [6]. Thus, EDS is common worldwide. People who suffer from EDS sleep a lot during the daytime and usually have cognitive and memory problems. In addition, EDS might be associated with impaired health-related quality of life (HRQOL) in patients with OSA [7] and narcolepsy [8-11].
