Akangaroo rat can survive vwithout ever drinking any water by getting needed moisture from seeds. It has pouches on the outside of its cheeks, which ituses to carry seeds back to its burrow.A researcher is studying spatial memory in kangaroo rats by running the rats through a radial arm maze designed to measure spatial learning andmemory. Each rat's score is equivalent to the number of arms of the radial arm maze it investigates. A higher score indicates a rat that is more curiousand therefore more spatially intelligent.Figure 1: A radial arm maze© Lynn Talton, 2008.

Please Answer just D,E,F Neuroscience researchers examined the impact of environment on rat development. Rats were randomly assigned to be raised in one of the four following test conditions: Impoverished (wire mesh cage – housed alone), standard (cage with other rats), enriched (cage with other rats and toys), super enriched (cage with rats and toys changes on a periodic basis). After two months, the rats were tested on a variety of learning measures (including the number of trials to learn a maze to a three perfect trial criteria), and several neurological measure (overall cortical weight, degree of dendritic branching, etc.). The data for the maze task is below. Compute the appropriate test for the data provided in Table below Compute the appropriate test using 5% significant level.

In a classic study of infant attachment, Harlow (1959) placed infant monkeys in cages with two artificial surrogate mothers. One “mother” was made from bare wire mesh and contained a baby bottle from which the infants could feed. The other mother was made from soft terry cloth and did not provide any access to food. Harlow observed the infant monkeys and recorded how much time per day was spent with each mother. In atypical day, the infants spent a total of 18 hours clinging to one of the two mothers. If there were no preference between the two, you would expect the time to be divided evenly, with an average of μ=9 hours for each of the mothers. However, the typical monkey spent around 15 hours per day with the terry-cloth mother, indicating a strong preference for the soft, cuddly mother. Suppose a sample of n=9 infant monkeys averaged M=15.3 hours per day with SS=216 with the terry-cloth mother. Is this result sufficient to conclude that the monkeys spent significantly more time with…
A developmental psychologist experiment to determine if exposure to an enriched environment shortly after birth will cause increased brain development. Twenty, two-month-old rats are randomly selected from a pool of one thousand two-month-old rat pups. Ten of the twenty pups are exposed to an enriched environment for three weeks and the other ten to the usual environment for the same period of time. At a suitable time after the exposure, the psychologist measures the number of neurons per cm3 in each rat's brain. A comparison is then made of the mean number of neurons per cm3 for each group.a. What is the population?b. What is the independent variable?c. What is the sample?d. What is the statistics?e. What is the dependent variable?
A team of psychologists studied the concept of visualization in basketball, where players visualize making a basket before shooting the ball. They conducted an experiment in which 20 basketball players with similar abilities were randomly assigned to two groups. The 10 players in group 1 received visualization training, and the 10 players in group 2 did not. Each player stood 22 feet from the basket at the same location on the basketball court. Each player was then instructed to attempt to make the basket until two consecutive baskets were made. The players who received visualization training were instructed to use visualization techniques before attempting to make the basket. The total number of attempts, including the last two attempts, were recorded for each player. The total number of attempts for each of the 20 players are summarized in the following boxplots. (a) Based on the boxplots, did basketball players who received visualization training tend to need fewer attempts…
A neuroscientist is interested in testing the effects of environment on dendritic branching in the hippocampus (dendrites increase the receptivity of neurons and may be an important basis of cognition). To test this, he took one group of rats (n = 11) and housed them in an “enriched” environment (consisting of a large box with tunnels to run through, toys to play with, etc.) and then he took another group of rats (n = 11) and housed them in an “isolate” environment (rats were housed alone without any tunnels or toys). After 6 weeks, the number of dendritic spines in a particular region of the hippocampus from these rats was imaged and counted. The results are below. Did the different housing conditions have an effect on the number of dendrite branches? Solve using the steps in hypothesis testing. Enriched condition Isolate condition Mean number of dendrites 40 10 (Estimated) Standard Deviation 10 4 Question: Calculate the upper 95% confidence interval…

Should advertisers worry about people with digital video recorders (DVRs) fast-forwarding through their TV commercials? Recent studies by MillwardBrown and Innerscope Research indicate that when people are fast-forwarding through commercials they are actually still quite engaged and paying attention to the screen to see when the commercials end and when the show they were watching starts again. If a commercial goes by that the viewer has seen before, the impact of the commercial may be equivalent to viewing the commercial at normal speed. One study of DVR viewing behavior is described in the article "Engaging at Any Speed? Commercials Put to the Test."† For each person in a sample of adults, physical responses (such as respiratory rate and heart rate) were recorded while watching commercials at normal speed and while watching commercials at fast-forward speed. These responses were used to calculate an engagement score. Engagement scores ranged from 0 to 100 (higher values indicate…

Dyslexia refers to a specific reading disability that affects 10% to 15% of the general population. A dyslexic child is defined as a child of normal or above-normal intelligence with no known organic behavioural disorders who, despite normal schooling, shows a reading lag of at least two years. A researcher proposed that dyslexia was the result of a complex visual deficit that could be immediately corrected by simply putting a blue plastic overlay on the reading material. To test this, 100 dyslexic children were randomly assigned to one of two groups, one of which read from pages with a clear plastic overlay and the other of which read from pages with a blue plastic overlay. The dependent variable was percentage correct on a multiple-choice reading comprehension test. a) Is this an observational study or an experiment? Explain your choice. b) Why did the researcher use a clear overlay as one of the treatment groups instead of just having the children read the passage without an…

A neuroscientist hypothesizes that she found the region in the rat brain responsible for the motion of the right paw. She trains 20 right-handed rats in a specific task to push a lever to to receive a tasty pellet of food. After the all the rats learn the behavior, she randomly selects 10 of them a does a surgery to place an implant on the brains of rats through which a lazer can deactivate the said region in the brain. After the rats heal, she runs all the rats through the same task. While 10 of them went through the experiment unbothered, the other 10 who had the implant were stimulated by a lazer through their implants to disrupt the functioning of the hypothesized critical region. The neuroscientist collected the amount of rewards(number of food pellets received)the rats in both groups were able to collect:Xsurgery: 2, 4, 3, 1, 5, 3, 4, 1, 3, 4Xcontrol: 5, 6, 4, 6, 8, 9, 2, 5, 6, 3 d. Calculate 95% confidence intervals for the estimate of the difference.
