Based on function, the author argues that having a lateralized brain is advantageous at individual level. Another discussion is based on vertebrate lateralization. Attempts to explain the evolution aspect reveal that evolution of hemispheric specialization in vertebrates demonstrates the asymmetric evolution that occurred in chordates. Presented evidence on the asymmetry reveals that the left hemisphere specializes on routine communication. This explains the origin of human language. The developmental aspect on the other hand reveals how the steroid hormones of the endocrine system affect lateralization. Questioning of causation results in clarification on how the two brain hemispheres work hand in hand in order to categorize and respond to the outside stimuli.
The application of current knowledge on hemispheric specialization is evident in the essay; an understanding of the potential knowledge is enough to improve animal welfare. Furthermore, techniques to study behavioral lateralization in both humans and animals in the future are also evident. Generally, the writing analyses the brain asymmetries in the entire animal ...Download file to see next pagesRead More

Minds, Brains and Programs

...acknowledges that cognition is not just a matter of formal symbol manipulation since the robot reply incorporates causal relation with the external world. Additionally, by putting such perceptual or motor capabilities provides nothing by way of understanding or intentionality with regard to Schank’s original program as well. The Combination reply: It combines all the three replies into a single shape of description. For example, consider the computer programmed with all synapses of human brain; imagine the whole behavior of the robot is not distinguishable from the human behavior and imagine a robot having a brain-shaped computer lodged in its cranial cavity. Now, consider this entire set up as a unified...

Biology Research Paper on Brain Tumors

...?(Add (Add (Add Information) (Add Brain Tumors Brain tumors Medical dictionaries define brain tumor as ‘an intracranial solid neoplasm’ or ‘a tumor within the central spinal canal’. Simply, brain tumor refers to transformation or abnormal growth of brain cells; this condition may be cancerous or non-cancerous. The NCPC defines brain tumor as “any intracranial tumor created by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the...

The Divided Kingdom

...building the temple to God and setting administrative guidelines for the priesthood. Solomon’s unfaithfulness and failures are underscored by rampant polygamy, wandering after many false gods and burning incense to them. These failures set Israel on a primrose path spiritually and led to Israel being divided into Israel and Judah. The idolatry that many of Solomon’s wives introduced in Israel set off a polytheistic trend and opened up the way to religious syncretism in both Judah and Israel. Lesson 4.2 Question 1: Relations between Elijah in the Northern Kingdom of Israel to the Religious Conflicts and To the Stories of Moses It is also interesting that both Moses and Elijah fast for 40 days and nights (Exodus 20:18 and...

A Class Divided

...A Divided Task I have learnt that racism existed in America and children too were racists since during time, their teacher asked questions about racism, and they think that people of a different skin color are not treated as brothers. The scene that will remember the most is the one that the children blankly say that the black people and Indians are inferior to the white people. I will remember the scene since I did not expect children of such a minor age to be racists and honestly think that people should not be prejudiced based on their skin color. The scene that the teacher asks the children the people that they do not treat as their brothers, and they give the answer black people and the Indians surprised me. I am surprised... ...

...Psychology What are two kinds of evidence that consciousness depends on a functioning brain? To start with, damage to the alerting areas of the brain, the brain stem and the midbrain, most likely can result to loss of consciousness. The first evidence is that consciousness cannot exist without the cortex working accordingly. Without this part, it would not be possible to comprehend speech, plan, move, solve problems, or express emotions. All these are aspects of consciousness. Second evidence is the brain stem. The hypothalamus is responsible for the sleep cycle; therefore, the suprachiasmatic nucleus controls the preoptic nucleus that induces sleep. By inhibiting the...

Divided attention recognize different shapes. An observer can identify the form of an object through the identification of its contours. The goal of this experiment us to determine the effects of dividing attention on the perception of the object outline. The experiment involves a psychophysical exercise that wholesomely depends on object shape perception. Participants study one object and later on study two objects simultaneously. The first task acts as a control experiment for the second task. Divided attention decreases one’s ability to analyse two shapes at the same time.

A Class Divided

...A Divided It is a wonderful social experiment. The experiment proved that it had a lasting impact on the children. They went through the experiment when they were children and they still had those thoughts, feeling and most importantly, the lessons embedded in their minds, after 14 years. Jane Elliott did her part and her experiment was a success. When she huddled them in a group after so many years and asks them ‘was the agony worth learning the lesson?’ and they reply in unison “yes”. The proof that lesson had been learnt is when Jane hears from her student when her son comes back home saying “nigger”, she tells him not to judge people based on their skin color. It is not from the outside that you judge a person, it...

Preschoolers grow their brains

...PRESCHOOLERS GROW THEIR BRAINS The article is a very interesting one and emphasizes on inculcating problem-solving skills among children especially those in the preschool. The idea of allowing the young children solve their problems with minimal supervision would lead to a more grown and creative child. In the 21st century, it is an essential attribute that cannot get evaded as proposed by Metiri Group 2003. Inculcating these skills would help the children be in a higher place in solving the problems that come up in the future in this ever changing world (Shelby and Christie 35). According to our article, children should be taught how to use their brains in coming up with their solutions. It helps in...

The class divided

...The Divided The Divided In the documentary, Divided, Jane Elliott uses differing strategies to addressprejudice and discrimination. Among the strategies include making comparisons between the children in an attempt to make self-identification. The teacher begins with commending the brown eyed learners by saying they are smarter and then does the vice versa with the blue eyed learners (McFadden & Peters, 1985). Through this strategy, the teacher minimizes the chances that one group may be termed as inferior to the other group. Through the use of influential training, the teacher uses this strategy to explain how the physical features of the learners are just mere appearances that need not influence the learners to have prejudices... that...
