Charles Galton 's Theory Of Differential Psychology

Howard Gardner developed the Multiple intelligence theory. Gardner believed that the human mind did not have one general intelligence but many that had independent functions. He believed that the previous measure of intelligence did not accurately measure the capability of the human mind. "While formulating this theory, Gardner placed less emphasis on explaining the results of mental tests than on accounting for the range of human abilities that exist across a vast majority of cultures.

There are a slew of tests that attempt to measure how intelligent human beings are. They all measure different aspects and those factors will be covered here. One of the misconceptions is that the tests measure inborn intelligence. Few of the activities are designed for that purpose. They actually measure a person’s interaction with the environment and what they have learned from that interaction. The most common tested aspect is critical thinking. Instead of straightforward questions, intelligence tests offer questions with a twist. It is assumed that the most intelligent people will see obvious flaws in the obvious answers (Steinberg & Williams, 2015). Some intelligence tests also measure reflexes, both mental and physical. The assumption is quick reaction times reflect an active brain and in the line of thinking, a more intelligent person.

Sir Francis Galton (1869, 1883) quantified traits that were assumed to be correlated, and developed the first comprehensive test of intelligence. By the end of the 19th century, the foundation was laid for modern day intelligence testing (Wicket, 1998). In 1905, the French psychologist Alfred Binet published the first modern intelligence test to identify students who needed special help in coping with the school curriculum (Neiser, et al. 1996). Shortly thereafter in 1908 and 1911, Alfred Binet and Theodore Simon published revisions of the Binet intelligence test (Wicket). The mental age concept was adopted to express the results in adequate units. The concept is based on an individual’s performance in comparison to the average performance of individuals in a specific chronological age group (Kaplin, & Saccuzzo).

On the contrary, those people who scored low on one kinds of ability test, were more likely to score badly on others as well. Meanwhile, Spearman also concluded that intelligence is a cognitive ability which could be measured and expressed numerically.

The psychodynamic approach to psychology is the study of human behaviour from the point of view of motivation and drives. The original beliefs of this approach were created by Sigmund Freud in the 1800s. Although it is now generally seen negatively in the common view, sometimes comically, it has provided the inspiration for a few of the current leading approaches to psychology.

Charles Spearman’s theory (1904) also takes the psychometric approach that there is a general intelligence. Spearman maintains that intelligence is hereditary and an individual is born with their maximum mental ability. This suggests that intelligence cannot be changed or strengthened. The concept of ‘general intelligence’ suggests that an individual has an underlying intelligence, in which their performance in one type of cognitive task is often similar to their performance in another (Boundless 2013). Spearman demonstrated this through the correlations between tests, where individuals who performed well in one test, often performed well in others. This led Spearman to the conclusion that intelligence is defined as a single factor. However, critics refute Spearman’s conclusions, as they argue that one cannot reduce all factors of intelligence to an indefinable “g” (Neisser et al. 1996).

Although Charles Darwin is usually just looked at in the light of purely biology, his work that impacted other fields such as psychology or his work that lead to the rapid expansion of certain fields such as ethology, is often looked over. Darwin’s work impacted these fields both directly and indirectly at such a level of influence that some people believe that psychology should be looked at as pre- and post-Darwin. On the Origin of Species, while being primarily about biological phenomena and theories, was one of these works that impacted psychology indirectly. Other than giving a new perspective for psychologists to possess when contemplating different ideas, Darwin’s work on natural selection lead to the creation of evolutionary psychology.

Jones and Butman (2012) in the text explain that cognitive therapy is a popular and extensively studied theory of understanding human personality. Cognitive therapies theorize that behavior is determined by internal or mental events. Initially the theory focused on identifying and changing maladaptive thoughts. However, recent models of the theory seek to help people evaluate, and change their thoughts, beliefs, and assumptions. In addition, newer models of the theory seek to help clients and understand the interactional nature of their thoughts and behaviors. Jones and Butman acknowledge that cognitive therapy models lack a theory of personality development (Jones & Butman, 2012).

Sharing the same principle, Nazi eugenicists also focus in investigating heritable traits. Galton argued that mental abilities are heritable, and people have the responsibility to maintain these “natural gifts.” He claimed that the failure of Athenian women to reproduce resulted for the Greek civilization, which he considered as the “ablest” race, to disappeared. This then suggests that maintaining desirable heritable traits is necessary for the improvement of human races population. With hereditary traits as center of eugenics, eugenicists started to investigate the role of hereditary in different diseases and characteristics. For instance, Karl Pearson investigated the influence of hereditary in intelligence, mental illness, alcoholism

His family was full of practicing medical physicians: his father, uncle, brother, and a few other relatives. Even though it seemed that everything pointed him into the

History and Systems of Psychology is a course requirement offered to Psychology majors and minors. This course is used to provide majors and minors with the foundation and the evolution of the field of psychology. Within this class, many scholars of discussed. Two scholars that stood out to me in this course would be John Watson and Max Wertheimer. These two particular scholars are responsible for two of the most influential and famous schools of thought, behaviorism and Gestalt psychology. These two schools of thought are responsible for changing the field of psychology and introducing the field to new theories and ways of thinking. Although the two schools of thought are similar in being influential but they are different in many ways. The two schools of thought are even said to be contradictory of one another and one is even said to be the cause of the fading out of the other.

Francis Galton was know in psychology for his accomplishments in mental tests and his studies of genetics. Galton began by studying facial expressions of people from all ages. In 1884, he established an anthropometric laboratory for measurements of human form. These labs became the first psychometric clinics. People paid a fee to be examined and then was given a results card when they finished. He performed tests involving taste, touch and auditory. He discovered that as people age, they lose the ability to recognize high pitches. He performed these tests on men and women and showed that men have more powers of discrimination. He developed the tool of questionnaires and two forms of association tests. The first test involved the participant

Binet argued forcefully against the idea that intelligence is fixed or innate: "We must protest and react against this brutal pessimism (Lewontin, Rose, & Kamen, 1984)." However, those who translated his test into English tended to disagree, arguing that the test measured an innate and immutable, genetically inherited characteristic. After Binet's death in 1911, the Galtonian eugenicists assumed control, shifting the focus firmly toward genetic explanations by insisting that differences in intelligence between social classes and races were due to inherent genetic differences.

Psychologists have been focused on observing and understanding human behavior for centuries, dating back to the Greek philosophers when psychology and philosophy were considered one.Today, Psychology is the study of human behavior, beginning before birth and lasting until death. It is clear that the observance human behavior is a vast and profound source of data for psychologists. Early philosophers relied on methods of observation and logic. A physiologist named Wilhelm Wundt in the 1800’s began using scientific research methods in his study of mental processes. However, the situation was totally different in the beginning of 20th century when psychology still struggled to be regarded as a separate discipline with practical value(Mastering,2011). Psychologists had only begun to be accepted as a science. It was John B. Watson who established the school of Behaviorism and inspired many other psychologists to study patterns of human behavior and their mechanisms. Watson 's contribution to psychology is important not to underestimate; he studied animal and human behavior to come up with a methodology that would give Psychology a respected status among other scientific disciplines. This essay will focus on the biography and works of John B. Watson with a purpose to show why his works are important for Psychology today(Hergenhahn & Henley, 2013).

It is difficult to summarize psychodynamic theory without a brief discussion of Freud. Sigmund Freud is the father of psychoanalysis, the father of psychodynamic theory, and in effect the father of modern psychotherapy. Freud's notions retain quite a bit of popularity, especially his ideas that things are not what they seem on the surface. Because of his understanding of the mind and behavior, Freud considered that overt behaviors were not always self-explanatory (or perhaps "not often explanatory" would be the better term). Instead, these overt or manifest behaviors represent some hidden motive. Sigmund Freud was trained as a neurologist and specialized in the treatment of nervous disorders. His early training involved using hypnosis with the French neurologist Jean Charcot in the treatment of hysteria, the presentation of baffling physical symptoms (mostly in young women) that appeared to have no physical origin (Hall, Lindzey, & Campbell, 1998). Freud also partnered with the Viennese physician Josef Breuer who practiced a revolutionary "talking cure" to reduce patients' symptoms by talking with them about how they felt as well as using hypnosis to remove emotional barriers to their feelings. He eventually abandoned the use of hypnosis in favor of a process he termed "free association" in which he had patients talk about what was on their minds without censoring their train of thought. This led Freud to develop his theory of the human mind as a complex system that is
