Cortisol Experiments

Despite a lack of scientific academic education, Jane Goodall’s work on the chimpanzees made revolutionary breakthrough in the field of understanding chimpanzee behavior. It was all made possible by her firm belief on her unconventional methods which academics in the field eyed with cynicism and felt was pointless. Such pessimistic outlook on her efforts from established academics did not blight her morale; instead she carried on with her methods of analyzing the chimpanzee population with full enthusiasm and self belief.

Sixteen baby monkeys were used, four in four different condition. One where there was a cage containing a wire mother producing milk and a towelling mother with no milk. Second, with a cage containing a wire mother producing no milk and the towel mother procuring milk. Third, with a cage containing a wire mother producing milk and fourth, with a cage containing a towelling mother producing milk. He then recorded the amount of time spent with

According to Alfred Adler, the birth order of the children in a family will largely affect how they age and the personalities which they will form. First borns enter the family as the only child. They revel in the love and full attention from their parents, that is, until the second baby comes along. Suddenly, first borns are dethroned and lose the undivided attention they are used to receiving. As a result, they tend to develop a strong sense of responsibility and protectiveness over their siblings at an early age, which often leads to them becoming authoritative adults. Moreover, when there are multiple children in the family, parents will set high

It is commonly believed that dropping levels of oestrogen and progesterone trigger the depression that many new mothers feel.

Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.

​Each individual of humankind was born with a natural curiousness about oneself and one’s surroundings. Seeking the truth and explanation of those things is human instinct. In the past, the ancestors believed that any natural phenomena were created by supernatural powers of God. After hundreds or thousands of years, these phenomena have been logically explained by scientific methods and theories. However, in 20th century, when these two different explanations interpreted with each other, it became a controversial issue questioning which one was right and which one was wrong. The Scopes Monkey

On Friday, March 31, a observation study was conducted at the L.A. Zoo. The time of arrival for the observation was at 11:48 am and the end of the observation was at 2:42 pm. The weather condition at the zoo was very sunny with a mild gust of wind every so often, which is a perfect weather condition to conduct a study. The main reason for conducting this observation study was to study and gather information about the many different types of primate that are located at the zoo. To see how different or similar each primate is to one anotherin different aspects.

The experiment was very controversial because it was very unethical and the monkeys suffered a lot of pain, and in some cases died of overdose.

Within this essay, we will study more in depth the behavioral as well as physical traits of two primates at a zoo from their interaction with their peers to their place in the group. This observation would enable us to further understand the possible existing correlation between humans and primates. First, I studied a female chimpanzee with her baby, and then, a dominant male gorilla, in San Francisco Zoo at about noon, on May 23, 2015, for an hour each. Even though they share some similarities such as having a large brain, living for a long time, and being bored in their enclosure, they are still different; when gorillas are the largest, chimpanzees are the smartest. In fact, chimps use tools to catch food, they would not be able to reach

In 1988 at the University of Zurich, Eduard Stammbach set up an experiment with long tailed macaque monkeys to determine if they were able to rein aggressive behavior and act cooperatively. Subgroups of monkeys were created, and the lowest ranking monkey was taught to press a set of levers in a specific sequence that caused a machine to deliver popcorn. The high-ranking monkeys noticed the low ranking monkeys’ unique skills. The high-ranking monkeys soon began grabbing all the popcorn. Before long the low ranking monkeys stopped operating the machine. This did not last long because the higher-ranking monkeys began to change their behavior. The higher-ranking monkeys began to approach the lower ranking monkeys more peacefully, and allowed the lower ranking monkeys a share of the popcorn. Furthermore some higher-ranking monkeys began to groom the lower monkeys even when the machine was inoperative.

Maternal stress also plays a role in the prenatal development affecting the length of gestation. Most commonly, maternal prenatal stress affects birth outcomes including prenatal delivery. Emerging research suggests that measures of pregnancy-specific stress are better than measures of general psychological distress for predicting developmental outcomes including preterm delivery (Davis & Sandman, 2010). Goals from the study in this article investigated maternal cortisol and stress and how each affects cognitive and motor development. Women who reported having higher levels of stress during the prenatal period reported a strong correlation with cognitive and motor development were associated with a stronger correlation of cognitive and motor development in their children, and reported higher levels of stress and anxiety earlier in pregnancy. However, one could question the validity of this report because the information was self-reported.

4). It is also believed that this exposure can contribute to the development of mood disorders later in life. On the other hand, Deward (2008) states that while cortisol can cause miscarriage early in pregnancy, the mother naturally develops higher levels in later trimesters, which in turn help the baby 's development. Because chronic and serious stress can be harmful during pregnancy, Broderick and Blewitt (2015) stress the importance of reducing conflict and providing strong social support to the pregnant mother.

Whether animal experimentation is justified or not has been undecided for many decades. Many years back, the debate was carried out by animal rights groups which were led by the Cambridge University to get rid of its plan for a primate research in 2004. Since this debate, many supporters have become more confident in speaking out what they believe and getting their points across to people.

(Jaffee, 2012). Infants who have parents who suffer from postpartum depression show patterns of an impairment in the physiological regulatory mechanism system. Mothers who suffer from postpartum depression are less likely to stimulate their child ( Murray,

Various primates show ability in their environment, some concepts may exist to other than human species or it may not. The author explains in depth the certain behaviours that come with forms of communication. Throughout this article, understanding the behavioural reasoning to observe predictions from one another. Social environment has been said to be suggested to represent the components. This mainstream article published online has a brief report and explains the facts by categories and only facts not opinions or comments. The specific format which describes the details right away and by the following paragraphs that help me understand it easier because it is not hard to read, the concept is right then and there. I like the fact that this article demonstrates the behavior of primates in formats that are understandable and can represent debate lies. Within assumption the examples given of behavior were simply a chimpanzee trying to go up a tree. A few chimpanzees took different roles tring to help each other up a tree. Experiments are said to look for evidence for primate subjects not just performing an act but also understanding
