Nature and Nature in Cognitive Development Essay Why are both nature and nurture important in perceptual development? How do both help a baby’s brain and sensory organs to develop?   The question of whether nature or nurture is more important in terms of perceptual development has bee long debated. In general, there are two theories that explain how humans develop these perceptions. The Nativists claim that our brains are built or hardwired to recognize certain stimuli by both design and construction. In contrast, an Empiricist would say that we learn through experience how to perceive things. There was an experiment done by Nativist researchers that sought to determine how very young mammals are able to perceive. The data concluded that early infants were able to perceive quite a lot before they really had a chance to learn anything. Gibson and Walk’s the â€Å"visual cliff† experiment was one such experiment, in this test both young animals and 6 month old human infants were taken to a side of a visual cliff, the test subjects would avoid the clearly deep drop. This indicated that children can perceive visual depth and that visual depth dominates even touch information. Additionally, studies have been done that show babies can recognize faces and that they often prefer the visual stimulation of carton faces as opposed to the same features arranged at random. In other tests it was shown that babies can also recognize whether or not and object is coming directly at their face or not. These experiments show that even the undeveloped infant brain has considerable capacity for perceptual capabilities. In contrast, several Empiricists experiments have been done as well. In one such study, scientists sought to determine the effects of depriving developing animals from perceptual stimulations. These tests have consistently shown that the longer the subject is deprived, the more severe the consequences. For example, humans are sometimes born without sight, due to a clouded cornea. Later in life some elect to have surgery to repair this clouded cornea. The result is sight, these people can see but they cannot perceive what it is that they see. As time goes on they slowly learn to distinguish one object from another, but this is however quite easily interrupted. Often changing an objects position or context is quite enough to slow down or prevent recognition. To conclude, although some argue that perception is due to nature, while others argue for nurture, it may in fact be that the two factors are interdependent and rely on each other. Support for this idea comes from an experiment that studied rats and found that those raised in a perceptually restricted environment had smaller brain development than those raised in an enriched environment, suggesting that while we are born with innate capabilities we need the environment to ensure we develop our abilities to perceive well. The perceptual capabilities we have at birth must be strengthened continuously through perceptual stimulation, furthermore, it would seem that perception in general follows the use it or lose it principle. Just as unused muscles become week, so to do our senses if left unused. Nature and nurture are both essential to health y perceptual development; stimulation begins in the womb and quickly follows all the way through adulthood. Sources .

Behind the walls of the Ghetto Essay -- essays research papers fc

Behind the Walls of the Ghetto   Ã‚  Ã‚  Ã‚  Ã‚  Commenting on the famed Los Angeles ghetto in which he grew up, gangster rapper Ice Cube asserts, â€Å"If you ain’t never been to the ghetto, don’t ever come to the ghetto† (Cube, Ghetto Vet). But why are American ghettos filled with so much violence, drugs, and inopportunity? In John Singleton’s powerful drama Boyz N the Hood the harsh reality of youths growing up in South Central Los Angeles, a place where drive-by shootings and unemployment are rampant, is brought to life. Shot entirely on location in South Central LA, Boyz N the Hood presents its story with maximum honesty and realism. The movie is a prime example of how American ghettos are dead end environments with minute chances for survival. If we are to put an end to the destitute, prison-like ghetto environments, we first need to take a look at what goes on there.   Ã‚  Ã‚  Ã‚  Ã‚  One can point to many initiating factors from racism to property owner’s aspirations of gentrification that create ghettos. Furious Styles, the strong and intelligent father of the film’s main character Tre, addresses the issue of why these areas are in such a dire state when he says: [†¦] How do you think the crack rock gets into the country we [black people] don’t own any planes, we don’t own no ships†¦we are not the people who are flyin’ and floatin’ that shit in here [†¦] why is it that there a gun shop on almost every corner in this community? [†¦] For the same reason that there’s a liquor store on almost every corner in the Black community, [†¦] they want us to kill ourselves. You go out to Beverly Hills you don’t see that shit, the best way you can destroy a people is if you take away their ability reproduce themselves. (Singleton) In this passage, Furious presents ideas of white property holders looking for the best way to exterminate the Black and Hispanic communities in their area. The late rapper Tupac Shakur once declared, â€Å"We [Black people] ain’t meant to survive cuz it’s a set up† (Shakur, Keep Ya Head Up). As far-fetched as these notions may seem, they may hold more truth than one thinks. Questions arise as to the relation between the ghetto and the upper class areas. Oddly, these communities, though only miles apart, are completely detached. In a study on ghettos in America, Ed Glaeser writes that: These districts commonly called ‘gh... ...r any other sport after college, is slim to none. At the very least, more high profile avenues out of the ghetto such as science and the arts need to be instituted in order to provide better opportunity for the futures of ghetto youths.

When reviewing the ratio calculations, it is apparent that the company’s likelihood of failing financially in the next 12 months is low. This is because it is apparent that the short-term debt paying ratios are down from the previous years. For example, the current ratio has decreased from the preceding year concluding that the current assets can cover the current liabilities successfully. Also looking at days to collect receivables is also lowered which presents that it takes less days for the company to collect their receivables implying that the monies owed to them are coming in more quickly. Lastly, in order for a company to succeed they need to have a good turnover rate for the inventory which is just what Pinnacle company has. The inventory turnover ratio is low indicating that it is taking fewer  days than before to sell invent ory.

Explain why.  I believe that the information in requirement d provides the most useful data for evaluating the potential for misstatements because you can see exactly what each division is claiming in each sub-category. When using the information in requirement c, you are getting an overview of what all the divisions have done and cannot tell which division each misstatement is coming from. Also, by using information from requirement d, the auditor has a better chance of depicting the misstatements because you are focused on one specific division instead of trying to figure out which division the misstatement might have been from. Requirement d is more informative than  using requirement c.

Multicultural Education Integrated Diverse Learners

This nation is integrated of diverse learners. Diversity in the United States includes race, ethnicity, gender, sexual orientation, socioeconomic status, cultural heritage, ability, and disability. As teachers, we have to help meet all of the student’s needs, so they can reach their full potential. Offering programs to help diverse student will help them succeed in school and life. Teachers can respond to diversity by practicing multicultural education, gender equality, considering students for programs like English Language Learner, and accommodating the student’s need according to their disabilities and abilities. As a teacher, a way to respond to diversity is to use multicultural education. Using multicultural education is a way to embrace diversity and combine different ideas. Multicultural education is developed so all students receive equal opportunities regardless of socioeconomic status, gender, sexual orientation, racial and cultural backgrounds. Socioeconomic status includes family income, parents education level, and family occupation. Students being male and female also have an impact, because they both learn differently. Also, one can be teaching students that have different sexual orientation. They can be lesbian, gay, bisexual, or transgender. These students will also need help by making them feel in a safe environment in which they can learn.
