The brain is three-layered or 'triune'. The three major layers or 'brains' were established successively in human evolution... first the reptilian brain or 'R-complex', the second the mammmalian brain or 'limbic system', and the third the neo-mammalian brain or 'neocortex'. Each has a separate function and depending on the circumstances each can become dominant but all three layers interact in the processing of information i.e. cognition or learning. The triune brain paradigm has forced a rethink of brain functioning or
Week 5 Forum Student’s Name Institutional Affiliation Date The amygdala and hippocampus are the main parts of the brain whose responsibility is the regulation of memory. The amygdala is divided into two, the right and left hemispheres. The right hemisphere is responsible for negative emotions like fear and sadness while the left hemisphere induces both the pleasant and unpleasant emotions when stimulated. These hemispheres have independent memory systems but they work together to encode, store and interpret information. The hippocampus on the other side is responsible for the production of corticosteroids (chemicals that produce physiological responses to stimuli).
Discuss the development of perceptual abilities. Include examples from infant and cross cultural studies in your answer (8+16) The development of perceptual abilities is explained through whether the ability is innate, which would be nature, or whether they are learned, which would be nurture. Thus forming the nature vs nurture debate. There are 2 theories of perception: Gregory’s top down indirect theory and Gibson’s bottom up direct theory. The top down theory states that our mind generates expectations about what we are looking at and these expectations help us make sense of the mass information that reaches our eyes.
6. Biological Psychology is the study of biological bases of psychological processes and behavior. Historical development of biological psychology, is explained by the fact that humans as well as animals can change according to environment, this is important in order to understand just how biology and psychology go together. This is an understanding that dates back to the ancient Greeks. Plato was the one that proposed that it was the brain that was indeed the organ of all reasoning.
Two stimuli are linked together to produce a new learned response in a person or animal. There are three stages to classical conditioning. In each stage the stimuli and responses are given special scientific terms. In stage one, the unconditioned stimulus produces an unconditioned response. This means that a stimulus in the environment has produced a response which is
Nature has selected advantageous variations from the mutations and new gene combo's produced at each human understanding. The genes selected during our ancestors history provide strong capacity to learn and adapt to life in varied environments. 2. Identify several methods used to study the brain and give a significant finding
Behavior is a product of the interaction between both genes and environment. The extent to which genes controls behavior differs from one behavior to the next. Each individual is innately born with a different set of genetic traits found only in that particular animal or species. While genetic change is a random process, natural selection chooses the more phenotypically fit opposed to individuals
In this view, the mind is a set of information-processing machines that were designed by natural selection to solve adaptive problems faced by our hunter-gatherer ancestors. This way of thinking about the brain, mind, and behavior
Phineas Gage’s accident had help so much by people being able to learn how the brain works and the functions of different parts of the brain. We were able to learn that different parts of the brain had control over different parts of functioning in the human body and the personality of the human body. (Willingham, 2007) The cerebrum holds brain cells that help in a person being able to learn. Learning is about learning new skills, in order for people to learn new skill that take stimuli. Stimuli’s are what transfers to the brain.
And what does it cost to the USA? The United States has an enormous prison problem. Today, the US has the largest prison population in the world. Although prison populations are increasing in some parts of the world, the natural rate of incarceration for countries comparable to the United States tends to stay around 100 prisoners per 155,000 people. The U.S. rate is 716 prisoners per 100,000 residents.
