An example of primary insomnia might be shift work insomnia where a person may well be attempting to sleep at times when their body clock tells them they should be awake. There are numerous subtypes of primary insomnia including; psychophysiological insomnia which is a form of anxiety-induced insomnia caused by a worry about getting a lack of sleep, idiopathic insomnia which is a lifelong sleeplessness and sleep state misinterpretation where people sleep adequately but feel they do not. Supporting evidence include Smith’s study where patients with insomnia were studies, as well as a control group of normal sleepers and they were studied for 3 nights with whole brain scans conducted on the third night. Patients with insomnia showed consistent and significant decreases in blood flow compared to good
| Sleep is one of the important dimensions toward health and wellness and not getting enough of it can have negative consequences. Sleep deprivation happens for many reasons; intentional and unintentional reasons. Often it is a sleeping disorder that causes the deprivation. Things like work, hobbies, television, or parties are activities people generally tend to put extra time towards, which could result in sleep deprivation. They are events we intentionally put forth time and effort even when it is cutting into our sleep time, though at times they are unintentionally overlapping into our sleeping.
Several specialized tests, which can be performed in a sleep disorders clinic or sleep lab, usually are required before a diagnosis can be stated. The two most essential tests in confirming a diagnosis of narcolepsy are the polysomnogram (PSG) and the multiple sleep latency test (MSLT). The PSG is an overnight test that takes continuous measurements while a patient is asleep in order to document abnormalities in their sleep cycle. A PSG reveals REM sleep that occurs at abnormal times in the sleep cycle and eliminates the possibility that particular individual's symptoms coming from another condition. The MSLT is performed during the day to measure a person's tendency to fall asleep and to determine whether isolated elements of REM sleep intrude at inappropriate times during the waking hours.
Why or why not? | Not unusual, because it is within 2 standard deviations of the mean | 8d. Fifty adults are randomly selected. What is the likelihood that the mean of their body temperatures is 97.98°F or lower? | 0.62 percent | 9a.
Chapter Four: Consciousness: Sleep, Dreams, Hypnosis, and Drugs * Understanding consciousness necessarily involves subjective experience. * An altered state of consciousness that may also be a natural state could be sleeping and hypnosis. * Hypnogogic sleep typically lasts for five minutes. * Your brain first begins to produce delta waves in the third stage of sleep. * One’s genitals will typically be aroused during REM sleep provided one’s dream is not anxiety provoking.
The alternative hypothesis H1 is that the mean annual income μ is less than $50,000. H1:μ < $50,000 Significance level chosen is 5% or α = 0.05 Here, the population standard deviation is unknown. Hence, we use a t statistic Therefore the test statistic used is t = X-μS/n follows a t distribution with n-1 degrees of freedom From the t table corresponding to 0.05 probability, the critical value tα =1.6766. Hence the critical region is t < -1.6766. Alternatively, we reject the null hypothesis, if the p value is less than the significance level Substituting the value we get t = 43.74-5014.6396/50 = -3.02 The p value corresponding to t = -3.02 and 49 d.f.

Discuss explanations of sleepwalking Introduction: Sleepwalking (somnambulism) is a condition where walking and sleeping occur at the same time, there are 3 explanations of sleepwalking: psychodynamic, neural and genetic. AO1 Psychodynamic: The psychodynamic theory suggests that sleepwalking is the expression of unresolved conscious conflicts. The sleepwalker is, in effect, ‘acting out’ repressed conflicts. The later finding that sleepwalking occurs during SWS was seen to support the psychodynamic theory, since the conditions of SWS are ideal for this to happen – the likelihood of recalling harmful repressed memories is minimal during this phase of sleep. AO2 Psychodynamic: The psychodynamic explanation of sleepwalking is supported by a case study (Abrams), it was suggested that the sleepwalking of the woman was a cry for help – the stealing being the reflection of her need to take control of her life.
Researchers gather pertinent information regarding sleep history, medical history, and physical assessments on participants is important. More extensive tests may be conducted, such as a Polysomnography. This is when people stay overnight in a facility under the care of professionals and have their muscle activity, heart rates, breathing patterns, eye movements oxygen levels, and unusual movements monitored (Dogrhamji,2008). These results are then measured and this gives the researchers the opportunity to evaluate the effectiveness of the sleep-aid. The evaluation can show if a person went to sleep more quickly, and slept more comfortably as usual and woke with no drowsiness.
