Sleep Deprivation
Summary
This research illustrates the alteration of sleep deprivation on attentional networks. The researchers found a problem with complete focus in everyday life, from lack of sleep, and wanted to figure out as to why this came about. Researchers of this experiment hypothesize that, “the tonic component of alerting interacts with both attentional orienting and executive functions” (Exp Brain Res 1), so henceforth, their experimental research study was conducted to see if sleep deprivation alters attentional function, both orienting and executive. In addition to their hypothesis, they needed to test said hypothesis by acquiring eighteen, right handed male university student participants to perform the study over the course of two consecutive …show more content…
days, at home. Furthermore what resulted of their experimental study, was that there was an increase in RT while the participants were sleep, and also a decrease on the orienting attentional network function. In essence, the researchers concluded that the results of their study illustrated a decrease of reaction time, during the duration from being sleep, which also then showed a decrease in vigilance and a tremendous breakage on both executive and orienting control.
Critique
The researchers of this experimental study, used 18 right-handed male participants from the University to test the alteration of sleep deprivation.
These participants then had to document their own sleep regimen for the duration of two days. The researcher then concluded that there was a decrease in both vigilance, and in the participants orienting and executive control. The researchers of this experimental study did use an adequate sample, however, in terms of this study, the duration of the experiment was not long enough. To acquire a substantial conclusion to their hypothesis, they should have prolonged the experiment for over the course of seven consecutive days instead of two consecutive days. However the methods from the researchers for their experimental study did provide a relevant supply of information for someone else to replicate their study. In their methods, the experimental research study was approved by the local ethical committee, so therefore they acquired their participants, and selected them as being right-handed, and also being able to finish a lateral preference questionnaire for the experiment. All participants were told that over the course of two consecutive days, that on the first day they were to perform a 20 minute training session of the attentional network test ,and that on the second day, they were to remain awake for the course of 24 hours during which the test was performed once at 5:00 PM and another at 4:00 AM. so therefore in essence, the researchers did use appropriate data collection methods to test their hypotheses on the alteration that sleep deprivation has on the orienting and executive control attentional networks of the human brain. Another way the experimental research study could have been done, is that there could be 20 male participants from the University, 10 of those participants being right-handed, and the remaining 10 participants being left-handed. Also the duration of the experiment would last at minimum, a
course of seven days, to acquire a more adequate analysis from the experiment study. The contribution of this research, to the field of psychology goes along with Polysomnography (PSG), which is a sleep study that is used to diagnose sleep disorders. Polysomnography records brain waves, breathing, the oxygen level in your blood, as well as eye and leg movements during sleep. As well as contribution to the field of psychology, it further helps the experimental research study on the effects of sleep deprivation on attentional networks. The indicated conclusions made by the researchers of this experimental study are well substantiated. Furthermore, they acquired great information from the experiment that showed the outcome of their hypotheses which resulted in being that sleep deprivation does affect the orienting and executive control attentional networks. All things considered, I for one, do agree with said conclusions made by the researchers for their experimental study on the effects of sleep deprivation on attentional networks both orienting and executive control.
