Extract

[...] Despite the critics, Gazzaniga's and Sperry's findings have recently been applied to explain how the hemispheres determine people's focus on specific professions and occupations. However, they should not be relied on to formulate education models based on the assumption that each brain hemisphere is responsible for distinct tasks in children. Thus, Gazzaniga's and Sperry's research is vital in understanding different disciplines. E. Conclusion Gazzaniga's article answers the question of the hemispheres considered two brains based on their independence, supported by Sperry's research findings. The split-brain research has significantly helped psychologists find treatments and explain dissociative and multiple personality disorders. [...]

[...] The research thus used three types of tests as methods to discover the wide range of perceptual and mental capacities of the participants. These tests included one to examine visual capabilities, the other for tactile stimulation, and the last test for auditory abilities Thus, by combining these tests, Gazzaniga would gain diverse and specific findings regarding brain functioning. B. Results The results revealed unusual mental abilities. The test for visual skills that involved flashing lights across the left and right visual fields indicated that the right hemisphere of the brain was dead. [...]

[...] They were given questionnaires, where one-half of the participants were asked if the leader of the four demonstrators that entered the class was male (Loftus 119). The other half were asked if the leader of the twelve demonstrators who entered the class was male. After a week, the participants were asked how many demonstrators they saw entering the class. In the results, the group with questions regarding 12 demonstrators saw an average of 8.85, while the other reported seeing 6.40 (Loftus 120). Thus, the wording altered the participants' memories.

[...] Loftus hypothesizes that if asked questions containing false presuppositions, the eyewitness could integrate the new false information to fill the memory gaps of the event (Loftus 119). Therefore, the witnesses' new memories of the events could become new testimonies and not a true recount. B. Methods and Results Four experiments were involved in the research. In the first experiment divided into smaller groups watched a film of a driver running into oncoming traffic after running past a stop sign, causing a five-car chain reaction accident. [...]

Philip Ross' article focuses on research that monitors people's brains to understand what is happening and how it functions through emotions, experiences, and thoughts. It also indicates various uses of MRI scanners other than showing tissue abnormalities. Therefore, Ross aims to discover the possibilities and effectiveness of fMRI (functional MRI), using MRI to detect human behaviors, thinking, emotions, and motivations. A. [...]
