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

In Harlow’s rhesus monkey experiment, Harlow placed monkeys in separate cages to isolate them, or leave alone without any interaction. In the cages with the monkeys, he placed a cloth. The monkeys laid on the cloths. When Harlow replaced the cloth, the

Action potentials can occur more frequently as long there is a continued source of stimulation, as long as the relative refractory period has been reached, which in experiment 2 the refractory period was complete.

One study attempted to observe capuchin monkey’s ability to recognize cause and effect relationship in regards to tool use. An article in the international journal or primatology by Anthea Lavallee, describes the tests she conducted in a captive naturalistic environment on capuchin monkeys, as she writes, “I tested tufted capuchins' ability to conceive solutions to a probing task in a naturalistic captive setting” . The results showed at 3 out of the 5 capuchin monkeys displayed an ability to make and use tools that were presented to them from a wide variety of natural materials presented. Another study on the manipulation and tool use in captive yellow breasted capuchin monkeys was published in the “International Journal of Comparative Psychology” . This experiment consisted of six capuchin monkeys, who were placed in an environment where their tool using was tested and observed. The tools that were made available to the monkeys were transparent 9mm Plexiglas boxes with 3mm Plexiglas lids as well as different size stones. A piece of food was then placed into the box with the stones next to it and left for the capuchins. Each test subject was left isolated with the tools and box from the other test subjects, the subjects where successful if they used the stones to try and

Research questions Dr. Hahn and her associates may ask would include things about how the chimp’s interact and communicate, about their diet affecting behavior and if different groups do things differently?

Using my Monkey Studies, when I separated infant monkeys from their mothers a few hours after birth, then

The study of primates has been a common field of study for a long time. The studies are carried out for different reasons but the common reason is trying to understand human beings better. Studies have revealed that the behavior of primates is similar to that of human beings on different aspects. Human beings and primates have a history of being related based on the evolution stories. The earliest human beings are believed to have been apes and evolved from there.

According to the data collected, the Intermembral index for each of the six primates observed from highest to lowest is: Gibbon (127), Howler monkey (102), Baboon (94), Macaque (89), Marmoset (74), Human (69). From this grouping, the Gibbon is the primate whose IM at 127 is the highest percentage, and this indicates that their upper limbs are significantly longer than their lower limbs. In contrast, the Human, with an IM of only 69 serves as the lowest percentage of the examples given, and this instead serves to demonstrate that their upper limbs are shorter than their lower limbs. This difference in limb length between the Gibbon and the Human is significant because it helps to show how species are adapted to best fit the environments

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.

All study procedures were conducted at the California National Primate Research Center (CNPRC). The study methods were approved by the Institutional Animal Care and Use Committee of the University of California-Davis. All rhesus macaques were

The part of the model that is being assessed here is the attention. Attention is located in between the sensory receptors and working memory (STM). The frontal/parietal cortex is responsible for the functioning of attention. Attention is thought to be the allocation of limited processing resources, in which an individual only has so much attention to give and an individual can choose where to focus this attention. There are many types of attention, sustained, selective, and divided. Sustained and selective attention, which are both being used when participating in the gorilla experiment, is when an individual
