#1 Responslve Brain Watch The Responsive Brain (you will have to scroll down to find the video) Its about 30 minutes, but you are only required to watch the first 9:30 (you can end at from Grief and Peril in Infancy) and then skip to 21.57 (the African plain scene) and watch to the end. Please review the study on the impact of human touch on premature infants in intensive care. 1. What was the hypothesis? 2. What was the V 3. What was the D? 4. What was the experimental group? S. What was the control group? 6. How was the DV operationally defined? 7. What do you think the controls were? What research method does Robert Sapolsky use in East Africa?Explanation / Answer
Answer.
the video ‘ the Responsive Brain’ traces the role of the brain and cognitive processes in the development of important social behaviour in humans and other species. It explores the universal need for touch at birth by showing how much the stimulation benefits development in children. Across a series of scientific researches. The first experiment shown is one by Saul Schanberg.
The narrator, Dr. Zimbardo presents the hypothesis of the videographic project as : physical touch and affection are significant to child development and both social interaction and social factors can cause physiological changes and divergences from the norm.
In the study, the presence of maternal contact or touch vs. maternal deprivation was the independent variable. The change in growth spurt which was hypothesised as related to maternal touch was the dependent variable.
The group of infants who were received care through touch from their mothers were treated as the experimental group and they were compared against the control group which was constituted by infants who did not experience any such exposure to maternal touch.
The researcher operationally defined the dependent variable in terms of changes in their levels of the chemical ornithine decarboxylase, or ODC which is asocietd with growth spurt such that a decrease in ODC in the experimental group lead to stunted growth of the rat pups.
In the experiment, the reseracehrs ensured that the findings were not influenced by intervening variables like previous experience with maternal touch and they controlled this factor by selecting a purposive sample of rat pups which were already deprived of maternal touch. In addition, factors such as nutritional health, age of infants could have been the possible factors which were controlled in order to avoiding confounding of the results.
