Hypothesis 1) There is a significant association between REM and reported dreaming.
Hypothesis 2) There is a significant positive correlation between the estimate of time spent dreaming and the measurement of REM sleep.
Hypothesis 3) There is a relationship between the pattern of eye movement and the reported content of the dream.

Participants were awakened 351times over 61 nights – average of 5.7per subject per night
21% in first two hours
29% in hours 3 + 4
28% in hours 5 + 6
22% in hours 7 + 8

Hi Kevin, I may of accidentally possibly not saved my completed Research Methods Grid.. however I do have a picture of it on my iPod as I asked my friend for help, am I able to type it up again for you tomorrow and get it to you for Thursday?

I have completed the four questions;

a) Outline the function of the hippocampus as described in Maguire’s study.
- The hippocampus is located in the medial temporal lobe and belongs to the limbic system. The limbic system is the set of brain structures that forms the inner border of the cortex.

b) Outline one difference between the MRI scans of taxi drivers and non-taxi drivers in Maguire’s study.
- The posterior hippocampi of taxi drivers were significantly larger in relation to those of

    After the initial four steps, you will return back to stage 1 EEG but this time it is accompanied by REM's which come with the loss of core muscle tone. This is now called Emergent stage 1 EEC or REM sleep. During the REM sleep is where we have our most vivid dreams that become stories or narratives when we recall them. There are five common beliefs about dreaming. One external stimulation can become part of your dream, this is true if water is splashed on you while REM sleep the water becomes part of you dream . Two dreams last only for an instant, this is not true dreams run on real time. Three some people claim that they do not dream, this is untrue if awaken during REM sleep they do report dreams only difference they dream less. Four penile erections are…

    There were 9 adults used in this study who were two females and 7 males. The individuals who took part in the study had electrodes on their eyes and scalp so they could measure eye movements and also record the individual’s brain. The individuals were woken up during rem and non-rem sleep many times in the night. However they were not told. There was a recorder that the participants had to speak in. they had to describe what their dream was and if it was either 5 or 15 minutes long. The results were that the individuals experienced rem sleep every night, it was faster. 80% was the mean of dream recall and the non-rem was 7%. This mean that the individuals were good at recalling the dreams in their rem…

    They may recall an image or various images from the dream; however, they cannot describe how the images connected to encompass the dream (i.e., as one would tell a story). Alternately, they may describe vivid images, with powerful feelings associated with the image and experienced both in the dream and upon awakening (Marszalek, J., & Myers, J.,2006).” From the waking mind to what is left of the dream, a lot of extra information that makes it easier to interpret that dream through plausible explanations has been forgotten. However, the information that the brain has retained since waking can still be explained. Whether or not a dream fills a desire or highlights and magnifies certain stresses or worries from the day, all dreams can be interpreted to have a connection to one’s emotional state and experiences from past or present. If an individual is preoccupied with some emotion, over some dilemma or desire, his or her dream is likely to be focused on those emotions and distort experiences, while the brain compiles the imagery, emotion, and any stimulus into a gripping plot that reflects…

    (page 188 Moorcroft). Moorcroft posits that, The process of synthesis during dreaming is no different from what occurs when you are awake. All us constantly synthesize the currently available sensory and motor information with our present affective state and then draw upon our memory banks of similar experiences and meanings to order to try to make it coherent (pg 189). On the other hand , according to the original version of this theory, a dream is catch as catch can synthesis by the forebrain, which is making the best of a bad job in producing even partially coherent dream imagery from the relatively noisy signals sent up to it from the brainstem” (Hobson & McCarley, 1977, p.1347). On the other hand, activation synthesis theory is not the best theory to explain dream. There are several critic of activation such as , being too neurological or too narrowly scientific to describe what dream is really about , there are people who have rems and do not dream and there are people who dream but don’t have rems , random stimulation of the forebrain that results in dreaming cannot explain the meaningfulness and it is based on animal brain research that may not apply to a mental functions in human” (Moorcroft…

    The human brain is a complex and sophisticated organ. Understanding the function of the brain is often limited to the understanding of the brains areas with regard to how these areas respond to stimuli or in cases of damage. Much of the understanding of the brain is rooted in observation of damaged brains and their correlation of impaired function with specific areas of damage. Modern technologies have begun to change this trend because tools such as the Magnetic Resonance Imager (MRI) allows scientist to observe brain function with the invasiveness of surgery. This technology has provided not just insights into neuroscience but also into psychology as brain functions can now be correlated better with behavior and heredity. One can see this insight when examining specific areas of the brain such as the temporal and frontal lobes of the brain.…

    Pavlides and Winson: Dreams as Information Processing also known as OFF-LINE THEORY (1989). These theorists contend that the cognitive process that occurs during dreaming consolidates and stores information acquired during the day thus allowing us to maintain a smaller and more efficient brain. The term Off-line is a computer phrase referring to the fact that computers need time when data are not being input but instead are being analyzed and stored into memory. According to this theory, dreaming is the time when the brain-out computer-goes off-line to somehow integrate the new information from the day with our older memories and experiences. Evidence that dreaming may indeed serve this function is shown in data suggesting that both humans and other species spend more time in REM sleep after learning difficult material.…

    2) During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep. Dreams can occur in any stage of sleep symptoms of REM sleep are Accelerated respiration Increased brain activity Eye movement Muscle relaxation Usually, REM sleep occurs 90 minutes after sleep onset. The first period of REM typically lasts 10 minutes, with each recurring REM stage lengthening, and the final one lasting an hour. Intense dreaming occurs during REM sleep as a result of heightened brain activity, but paralysis occurs simultaneously in the major voluntary muscle groups Most dreaming takes place during…

    The problem is that scientifically this idea is particularity hard to prove. No psychologist, machine, or doctor can see inside another person’s dreams. However, an experiment was done where subjects were instructed to signal the start of a lucid dream by certain dream actions that could be recorded on a polygraph. These actions were compared side by side to the recording of their sleep stages. Signals were shown on the polygraph mostly during REM sleep. (LaBerge, S., Nagel, L., Dement, W. C., & Zarcone, V., Jr. (1981). Lucid dreaming verified by volitional communication during REM sleep. Perceptual and Motor Skills) This data proves that the subjects were able to control their dream actions while…

    During the fourth and final stage of sleep is where most of your dreaming occurs, called REM sleep. REM sleep is characterized by eye movement, increased respiration rate, and increased brain activity. Your dreaming occurs in REM sleep because of the increased brain activity. Once REM sleep is over, the body usually returns to stage 2 of sleep and your sleep cycles through these stages up to 5 times in the…
