Forty Studies That Changed Psychology by Roger R. Hock, Seventh Edition

reading 1: one brain or two

Michael S. Gazzaniga conducted this study in 1967. Gazzaniga wanted to examine to what extent the two hemispheres of the brain could function independently. By severing the corpus callosum the two halves of the brain have an inharmonious relationship. The patients used in the studies were people who suffered from rare cases of epilepsy and seizures. After the patients, brains had been split they took a series of tests designed examine each ability of the brain. The patients would be shown a series of objects on both sides covered to one eye. When the researchers showed an image to the right eye the patient would verbally reply, but if an image

This study has helped pave the way for more research into patients with multiple personality disorder and dissociative identity disorder. Furthermore, little to none of the research found on the topic has been disputed, with the main criticism being the way the media has portrayed it. The media oversimplified the studies and research done into myths about being more right brained or left brained.

Reading 12: see aggression, do aggression

Albert Bandura, Dorothea Ross, and Sheila a Ross conducted a study in 1961 about aggression, titled 'Transmission of Aggression Through Imitation of Aggressive Models'. the study focused on children ranging in age from 3 years, to almost 6 years old. There was a total of 36 girls and 36 boys participating in the study. In the experiment, there was a control group of 24 children of different ages and sexes. The control group would not be exposed any model. The remaining children were also divided into two groups, the group exposed to a non-aggressive model and the group exposed to an aggressive

Ekman and frieste found facial expressions in western societies and westernized cultures all were easily identifiable and were curious about whether the same was true of people who were not exposed to western culture or films. They went to Papua, new guinea to see the South fore people. The participants were 189 adults and 130 children that have not been exposed to western culture. For a control group, they had 23 adults with experience of western culture. The participants were all read a simple story and asked to pick from a selection of images which one best represented the emotion in the story. The children were overall better at identifying the emotions than the adults were except for with anger, in which they were equally good at identifying as the adults. All participants had relatively easy time identifying the emotions and faces, the only confusion being with fear and surprise because the two are often linked. In regards to the children having an easier time identifying the emotions than adults, they attributed that to the fact the children only had to choose between 2 pictures instead of 3. this research has been used to prove what was already suspected and to attempt of help us gain a deeper understanding of children and adults with learning
