Compare the Social Brain Hypothesis and the Visual Specialisation Hypothesis The aim of this essay is to investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group

a reality that is not real? A person has an experience that is not real‚ but believes it to be real. Can that person reach the same conclusions and learn the same lessons from that false experience as from an equivalent real experience? Does the human mind perceive false realities any differently compared to the true reality lived out every day? Even though a moment in time or a series of events may be imagined or made up‚ people learn lessons and react to these phenomena in ways that are very similar

All people do not deal with traumatic brain injuries the same in the way that it takes people a different amount of time to recover than others and that it effects the patient’s qualities that they had prior to the injury differently. Traumatic brain injuries are common and they disable 150 million- 200 million people per year which is the leading cause of disability in people under 40 years old by injuring the frontal and temporal lobes. Recovery times are different for different people (most people

Why do humans have such large brains? Over a span of nearly seven million years‚ the human brain has tripled in size‚ with most of the growth being seen in just the last two million years. Although many explanations for the growth of the human brain have been presented‚ one hypothesis that proves to be most accurate is the Social Brain Hypothesis as presented by Robin I.M. Dunbar. This hypothesis attempts to explain the cause in brain size evolution by attributing it to social relations and social

Concussions The brain is a very delicate and complex organ . It is located inside the head and controls everything we do from movement ‚ our five senses ‚ emotions ‚ thoughts ‚ memory ‚ breathing ‚ our heartbeat ‚ digesting food and our speech . The brain is made of a gelatin like substance and is protected by cerebrospinal fluid and the skull . So imagine what would happen to our brain if it would get damaged . Anything that our brain controls could be altered either temporarily or

Traumatic Brain Injury (TBI) can occur frequently and may cause serious damage. TBI can happen when a bump‚ jolt‚ blow‚ or any head injury causes damage to the brain. MIllions of people a year suffer brain injuries in the United States alone. More than half of those million incidents require the patient to be taken to a hospital because of the severity of the injury. Depending on how severe the injury is‚ it could cause serious brain damage and potentially be life threatening. Half of all TBIs occur

the human brain results in its fourfold increase in volume between birth and adulthood and during this time frame there are also significant changes in cognitive ability‚ the most marked of which occurs in early infancy. It is only relatively recently‚ with the advancement of neuroimaging technology‚ that researchers have begun to examine how brain structure‚ that is its physical fabric and organisation‚ might relate to its function‚ i.e. the tasks it performs‚ in a child ’s developing brain.

there might be an impairment in their arousal when someone suffers a brain injury‚ thus‚ having an effect on the role of recovery in relearning a motor skill (Goldfine & Schiff‚ 1). In athletes who have suffered a concussion‚ they might have problems with arousal. Concussions often occur frequently in sports such as lacrosse or football and can change the ability for arousal for certain athletes. Knowing this‚ it will help me in trying to figure out what best ways to get the athlete’s arousal up

Human multitasking is the best performance by an individual of appearing to handle more than one task at the same time. The term is derived from computer multitasking. An example of multitasking is taking phone calls while typing an email. Some believe that multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention. Etymology The term "multitasking" originated in the computer engineering industry.[1] It refers to the
