Fiber cabling is growing very fast due to how much more efficient it is than copper cabling. Fiber, for one, has a greater bandwidth. Single mode cables offer the most bandwidth but you have the option of the single mode, 62.5 or 50 micron multimode cables. In addition to that, fiber can carry more information than the copper. Fiber can also carry over a longer distance with low attenuation.
Compare the mean baseline and posttest depression scores of the control group. Do these scores strengthen or weaken the validity of the research results? Provide a rationale for your answer. Ans: The main baseline and posttest depression scores are in control groups are same (10.40 and 10.40) the score is weakened because the fastest score should be higher than the baseline. 5.
Hitch and Baddley showed support for the WM by conducting an experiment where they gave participants two tasks to do at the same time. They found participants were slower completing these tasks when a task involved using both the central executive and the articulatory loop. This shows that you can't use two componants of the STM at the same time. Shallice and Warrington also showed support for the WM in the casestudy of a brain damage patient KF. The study showed that short term forgetting of auditory information was much greater than that of visual stimuli and his auditory
They were asked to recall words in the correct order given in the sentence. The more sense the sentence made (in grammar) the easier it was to recall. It implied that semantic meaning and grammatical structure is used to help increase amount of information stored in short term memory by combining items to create larger chunks. Participants were able to recall 7 pieces of information. The research suggests that capacity of short term memory could only be enlarged by grouping items together known as chunking.
Body Measurement Experiment Shane Cozort September 27, 2011 Biology 2010-51 Professor Martin Subjects: Gena Lyn, Kayli, Laura Beth, Karen, Morgan, Sara, Taylor, Cassi, Robin, Aaronda, Lauren, Mary Intro/Observations/hypothesis With the correlations among height and limb length, a study was conducted using the Scientific Method to determine if the arm has a direct relationship with the height of the person. The subjects for this study were 1 male and 12 female from Tuesday 1:20pm A&P lab class. These subjects were randomly selected and grouped by Professor Martin. These calculations can be of use in determining skeletal deformities, abnormalities of the spine, or if limb length is predictor of height. The aim of this study is to approve or reject the hypothesis being limb length (arm) is equal to 40% of a person’s height.
Despite the limitations found in the BCDTC, the findings of the research proved that subjects who participated in the DTC were less likely to be rearrested than the control group. The failure rate for DTC subjects was 66.2%. Failure rates for non-DTC subjects were 81.3% (Gottfredson, 2003).
This may seem to be an easy task, but once attempted it was made obvious that it takes much longer for the brain to process the fact that it has to say the color of the letters versus the actual word. Words take much less time to process than colors, which would explain why it took a longer amount of time to say the actual color of the text. Naming colors also requires a lot more attention than reading words. This would also be a reason as to why saying the color of the text might take longer. In order to see the difference between nameing colors with matching words and colors to nameing non-matching words and colors, we did three trials of each with five different test subjects and found the average of both tests.
In this way, students would learn more efficiently, study more regularly, and have less anxiety. Malley also proves that test provides better learning which is good enough to trade-off some lecture time and professors’ personal time. Similarly, he argues that compare with study questions, review questions and study programs; frequent tests seem much more
Research has found that ABI patients use an increased number of memory aids after their injury than they did prior to it and these aids vary in their degree of effectiveness. One popular aid is the use of a diary, studies have found that the use of a diary is more effective if it is paired with self-instructional training; this was related to more frequent use of the diary over time and proved to be more successful as a memory
The question that should be asked is what method should be chosen so that it will be the most cost and time effective? Small Groups VS Individual Expert as Problem Solving Small groups tend to surpass individual experts when alternative solutions are present. Due to the fact that small groups consist of multiple bodies, they can input there own specific experiences and unique knowledge into the task at hand thus coming up with an, if not better, answer than that of the individual. Group work causes less strain to the mind and well as it is a lot less time consuming. Typically higher quality work is present with multitudes of solutions.
