1. Prozac is an anti-depressant medication prescribed to treat people who have depression. One way to test and see whether Prozac is an effective drug to use for depression is to start an experiment. The first step in the experiment is to break the test subjects into random assigned two groups, one group is the control group, and the other group is the experimental group. The second step in the experiment is to give the control group the placebo, without informing them whether it is a placebo or the anti-depressant, thus keeping them blind, and the experimental group the Prozac, without informing them whether it is the anti-depressant or the placebo, which also keeps the experimental group blind. The independent variable in this case is the Prozac, while the dependent variable is asking and checking each group, the control and the experimental group, to see which one is doing better or feeling less depressed.
2. Correlational studies are a type of research in which the relationship between the two variables, independent and dependent, is studied without performing experimental manipulation of the independent variable. The reason Scientists can’t test lead poisoning on people or animals because it is inhumane, therefore, they find people already exposed to lead poisoning, and do research from there, which is called, “natural experiment,” where something already occurred by chance, or naturally, in the world outside the laboratory. Another example of natural experiment would be the West Nile virus, or exposure to Mercury, or Hg as an element, and the symptoms that occur from it.
The potential drawbacks of correlational studies are the difficulty of comparing two groups that were not randomly assigned. Therefore making it diffic...

...the motor cortex contains an upside map of our body represented as a homunculus, which it controls the motor movements of our body. Keep in mind that the left brain hemisphere and the right brain hemisphere do apply to the motor movement of our bodies, left hemisphere controlling the right part of our bodies and the right hemisphere controlling the left part of our bodies. The major functions of the frontal lobe include, motor movement, producing speech, and creating abstract thoughts. The parietal lobe, located in the rear of each frontal lobe, controls the sensations of touch, body position, and understanding speech. The temporal lobe, located at the lower side of each cerebral hemisphere, controls the hearing, smelling, and the recognition of faces. The occipital lobe, located at the back of the brain, controls what we see with our eyes, or in short, our vision.

The Brain Controls Body Functions Essay

- Currently, it is basic knowledge that the brain controls body functions and has voluntary and involuntary control over behavior. However, it was believed that behavior was due to cerebral localization and many studies have demonstrated support for this idea. Cerebral localization is a term that refers to how specific areas of the brain correlate with specific behaviors and functions. This concept was first utilized by Franz Josef Gall with phrenology. Gall relied on physical characteristics of an individual’s skull to be associated with certain regions of the brain, which later became known to be called phrenology....   [tags: Brain, Psychology, Cerebral cortex, Human brain]

Essay on Functions Of The Following Structures Associated With The Human Brain

- Briefly identify and describe the structure and function of the following structures associated with the human brain: external structure (lobes and fissures) of the cerebral hemispheres, ventral aspect, meninges, cranial nerves, and the internal structures (i.e., cerebrum, diencephalon, midbrain, brain stem, and cerebellum). The forebrain (prosencephalon) is divided into two parts the diencephalon (contains the thalamus/hypothalamus which are responsible for functions such as motor, sensory, and autonomic as well as the pineal gland), the telencephalon (contains the cerebrum most information is processed in the cerebral cortex), and the pineal gland (produces the hormone melatonin)....   [tags: Brain, Central nervous system, Neuroanatomy]

The Brain Functions for Language Process Essay

- Learning and expressing a language is an amazing capability that begins in the early stages of a person’s life. Several brain regions have been pinpointed as distinct language areas, such as Broca’s and Wernicke’s areas, but additional brain regions contribute to language processes as well. In addition to understanding spoken language, humans have the ability to comprehend music and to learn sign language if needed. Language acquisition starts early in life, especially the acquisition and learning of phonetics which is detailed in Kuhl’s review article....   [tags: spoken, language, music, acquistion, area]

Essay about Anatomy of the Brain and Its Functions

- The brain is the perception responder and critical thought processor. Along with the brain’s control of all physical action and coordination, it has all control over emotional response and impulse. The brain’s dictation of all normality and actions made are only a small concentration of what the brain is truly capable of and scientists are working towards expanding this theory. This has been such a controversial issue, compiled with the hopeful idea of a cure for brain disease, a daunting possibility that could potentially “blur the lines between man and machine” (Kate Kelland, 2012.) It has been a well-known fact that humans only use a small percentage of our actual brain capability....   [tags: cerebellum, frontal lobe, occipital lobe]

Essay about The Printing Press by Johannes Gutenberg

- In the 1450s, a German goldsmith named Johannes Gutenberg invented the printing press, which revolutionized the world of publishing (The Printing Press, 2005). Since then, hundreds of word processing programs have been developed, along with thousands of new fonts, from Times New Roman to Comic Sans. Marketing professionals and scientists around the world have wondered what kinds of fonts stick in a person’s memory over others (Dizikes, 2013). The concepts of how memory functions, how the brain processes information and how font and memory are connected in psychology are essential to better understand this idea....   [tags: memory functions, brain, impression]
