September 13, 1848 marked the day that Phineas Gage, a twenty –six year old foreman of a railroad construction outfit, experienced a horrific accident that not only changed his life forever but impacted man’s scientific understanding of the brain, both then and today. In Cavendish, Vermont, Phineas’ job was to blast solid rock into pieces small enough for his crew to dislodge and haul away. Necessary to conduct his job was a special tool, called a tampering iron. His custom-made tool was 3 feet, 7 inches long, weighing thirteen and a half pounds. The fat end of the tool was one and three quarters in diameter and the other end came to a sharp narrow point. To prepare an area for demolition, an explosive material was placed in a hole, a rope-like wick was implanted and more explosive material packed around. On this day an error in preparation caused a premature explosion, which shot the tampering rod through Phineas’ left under eye area and exited from the top of his head, where it landed approximately thirty feet away from him. He lived another eleven years, six months and nineteen days, eventually dying from this injury.
As most would conjecture, this occurrence should have caused immediate death. Surprisingly, he was talking to his men while in the back of an oxen-drawn cart into town. In fact, he was sitting on the porch of his hotel when the town’s physicians Dr. Edward Williams and Dr. John Harlow arrived. Although bleeding profusely, he remains “alert, uncomplaining, and still telling anyone who’ll listen about the accident” (Fleischman, 8-9). Subsequent to the incident, the profuse bleeding should have killed him. After that, swelling to the brain caused by the bleeding should’ve surely caused him to die. Also, the accident occurred before the understanding of bacteria and the causes of infection, no antibiotics existed, and sterile conditions were non-existent. Many attribute his survival to either luck or God.
Dr. Harlow took over his care as the town’s primary physician. He walked Phineas up the stairs to his bedroom, shaved his head, and dressed his wound. He did this without a sterile environment or even washing his hands. It was noted in Dr. Harlow’s medical records that indeed there was a hole in his head, which science has later confirmed that this is why there was no swelling in his brain as he had an ‘open’ injury vs. a ‘closed’ injury (referred to as a concussion today). He developed an infection a couple weeks after the accident in which the prescribed treatment was to drain the abscess. He physically improved and was pronounced healed just ten weeks after the accident. However, though apparently physically healed, Phineas had changed in character significantly from his prior self.
Previously a respected, efficient and capable foreman, Phineas insulted his colleagues, was unreliable in terms of showing up to work and extremely vulgar and cruel in his language. He was now impatient, quickly angered, and as is described throughout the book, has become void of social abilities. Phineas migrates towards animals and young children since his accident, and although he can understand logic, often his choices are not based on logic, but some innate desire.
Two years after the accident in 1850, Dr. Harlow brings Phineas to Harvard Medical College in Boston for examination. At the time of his accident there were two prevalent theories. The Whole Brain theory believed that the brain is one interconnected mind and that thoughts and commands can originate anywhere in the brain. The opposing theory, called Localizers or Phrenologists believe that the brain is divided into specific areas or organs that control specific things. We do know that specific areas of the brain control specific functions and behaviors, but not always as logically as thought back then. A plaster mold of Phineas head was taken which was used to mainly support/explain the Phrenologist
changing and gruesome injury. Phineas Gage was that man and he influenced theories and discoveries about the brain being responsible for a person’s personality to transpire. Phineas Gage is famous for many reasons that are deemed important to understand. Before understanding why he is famous, what exactly he has influenced, and why all this is important to know, his story must be understood first. It is the story of how a man survived and died at same time in one day. Phineas Gage’s story is important…
imitation. Evaluation: Laboratory experiment lacks ecological validity. Involves the use of strangers carrying out artificial behaviours. Biological approach Phineas Gage: 1848. Aim: To explain the cause of the change in Phineas’ personality. Method: Gage worked for Rutland and Burlington Railroad in New England at the age of 25. Phineas was preparing for a blast for a section of rock using explosives to create a new railway line; he accidentally dropped his tamping iron on the rock and the explosive…

theories on aggression through their research 3 in which environmental factors influence and provoke aggressive responses in both animals and humans. However, other theorists leaned more towards evolutionary biology. According to Morgan (2005), “Aggression could be environmental but it is undoubtedly genetic as prehistoric man has passed down his responses and behaviors to the subsequent generations and perhaps the lined has blurred between nature and nurture” (p.375).…

PLEASE DO NOT WRITE ON THIS TEST PSY 2012: Test 1 Review, Chapters 1-4 1. Mental process and what it involves The term psychology derives from the roots psyche, meaning “mind,” and logos, meaning “word.” Modern psychology is the scientific study of behavior and mental processes. Behavior is anything we do—from sleeping to rock climbing. Mental processes are our private, internal experiences—thoughts, perceptions, feelings, memories, and dreams. 2. Empirical Evidence Empirical evidence: Information…

Neural Response: the electrical and chemical transmission of info from one neuron to another by releasing chemical neurotransmitters into the synapse; communication within a neuron is electrical and communication b/w neurons is chemical 3.
