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 …show more content…

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 …show more content…

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

Our society is responsible for aggression. Many people argue that aggressive people were born with a predisposition to perform violent acts, but that does not settle with many psychologists’ studies. Other people believe that violent people were made from exposure to aggression during childhood. Both of these perspectives represent points of a larger argument started by Francis Galton 150 years ago most commonly known as “Nature versus Nurture”. After 150 years, and the founding of a new branch of science, epigenetics, scientists now have viable proof that that nurture is more influential in the case of aggression because epigenetics show that environments are responsible for gene expression.

Psychology, one of the most interesting subjects and most common major out of college. Psychology though is much more than studying behaviors caused by the brain. There is an intriguing history, rules and ethics for conducting research, and many categories under psychology. Psychology is a fascinating subject with many studies, science, and a lot of research. This is what psychology is today, but the history is less structured and scientific.

Children are like a plain paper who can be easily influenced by the environment of their living. The environment can affected the pattern of change in emotions, personality development and social relationship between people.

At early stage, emotions are personally responses to the environment of surrounding, it can be pleasant or unpleasant that someone usually experienced cognitively, come along with some form of physiology arousal and usually expressed in some form of behavior or action which can be seen.

While examining various types of aggression they measure children’s exposure to media violence and their aggressive behaviour during school years (Gentile, Coyne, & Walsh, 2011). After inquiring into the details of the topic, their results showed that children who consumed media violence in early school years had verbally aggressive behaviour (Gentile, Coyne, & Walsh, 2011). Some also showed high physically aggressive behaviour and were less social during their late school years (Gentile, Coyne, & Walsh, 2011). They further claimed that such effects were more prevalent in boys; while other forms of non-physical violent behaviour was visible in girls too (Gentile, Coyne, & Walsh, 2011). Media violence also seemed to have effects on the social information processing intent attributions which were found to be hostile.

In the filed of biology psychology, it is said that there are 3 areas of the brain that are mainly involved in our aggression and violence behavior, which are the hypothalamus, the frontal lobes, and the limbic system. Morley and Hall(2003) have investigated o how the human genes have an influences on their criminal behavior. In their research, they have found a positive relationship between criminal behaviors and genes. Brunner et al(1993) conducted an research on a Dutch family, the result showed that some of the family members from the Dutch family with tendency of aggressive behavior turned out to have mutation occurring in their monoamine oxidase A, a type of neurochemical in the brain. Therefore, we tell say that aggressive behavior is somehow related to human brain structure.

The age of onset in aggression is also a relevant factor in differentiating the nature and type of aggression. A significant amount of literature has indicated that aggression decreases throughout childhood (Dodge & Coie, 1998; Fite, Colder, Lochman, & Wells, 2008). However, there are differing beliefs as to when aggression reaches its peak. For instance, Tremblay (2000) posited that aggression peaks during preschool age as this is when children develop the capacity to inhibit their physical aggression, while other researchers have stated that aggression tends to come to its peak and begin to decrease around the fifth grade (Fite et al., 2008). Studies indicate that males tend to exhibit antisocial behaviours at a much earlier age than females

In this experiment gender was looked at as factor that influenced aggression. Many people tend to see men as more aggressive than women. The findings of the research found that there is no difference in aggression between males and females. However it was found that men do use more direct aggression then women but between the two genders both use indirect aggression the same as one other. Social connections is another way to look and see what type of aggression is used in day to day life.

1. Introduction Traditionally, psychologists measure aggression using self-report scales, which are designed to directly measure the explicit type of aggressive behaviors. Recently James and his colleagues (James et al., 2005; James & LeBreton, 2010, 2012) introduced a new approach to assess individual implied personality, called the Conditional Reasoning (CR). Building on the notions that people prefer to view their behavior as rational and appropriate, and aggressive people are seldom aware of the full extent to which they possess a motive to harm others (Westen, 1998); James and his colleagues introduced the concept of Justification Mechanisms (JMs).

Introduction Aggression is a form of social interaction, which is overt and often associated to be harmful that consist of intention of causing either damage or unpleasantness to another person (West, 2013). The harm of this kind can either exist in physical or psychological form. Its occurrence can be as a result of with or without provocation. The existence of blocked goals among humans can easily lead to aggression. This is a social issue among children, which often result in harming the society, community, families and themselves.

Aggression is a spoken or physical behavior that causes intentional harm to a person. There are many different theories that argue what the cause of aggression is but this can be divided into two major types: people who think that aggression is inborn and those that view it as a learning behavior. The Social cognitive theory states that we learn behaviors through observation and modeling and this could be implied that we learn aggressive behaviors through observing and imitating others. The Social Cognitive theory claims that people learn behaviors from observation, modeling, and motivation such as positive reinforcement. Psychologists mention that people learn behaviors by imitating models through observational learning; as well as through
