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... ... middle of paper ... ...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.
Experimental research is the one type of research that allows psychologists to make causal statements. It is where the researcher changes one or more variables that may have an effect on some other variables (King, 2016). The hypothesis is a specific expectation about what is going to happen in the experiment (King, 2016). In the research, the hypothesis was that women would perceive fat talk to be more socially acceptable than men (Katrevich et al., 2014). The other elements of experimental method are dependent and independent variables. The independent variable (IV) is the cause of the results, and it is changed by the experimenter to find the effects, but the dependent vari...
Although the brain only weighs about three pounds, it is a very powerful and essential organ in the body (Brain Structures and Their Functions). The cerebrum, cerebellum, and the brain stem are the three main parts of the brain. The cerebrum fills up most of the skull, its main functions are for remembering, problem solving, thinking, and feeling (Bellamy 23). It also controls movement throughout the body. The cerebellum is located towards the back of the head. It controls mostly just coordination and balance (Brain Structures and Their Functions). The brain stem is underneath the cerebrum and in front of your cerebellum. It attaches the brain to the spinal cord and controls functions like breathing, digestion, heart rate and blood pressure (Carter 12). The brain is also divided into halves. The left side of the brain controls the right side of the body, while the right side of the brain, controls the left side of the body (Bellamy 17).
The brain has four major lobes. The frontal lobe, the parietal lobe, the occipital lobe, and temporal lobe are responsible for all of the activities of the body, from seeing, hearing, tasting, to touching, moving, and even memory. After many years of debating, scientist presents what they called the localization issue, Garret explains how Fritsch and Hitzig studied dog with conforming observations, but the cases of Phineas Gage’s accident in 1848 and Paul Broca’s autopsy of a man brain in 1861 really grabbed the attention of an enthusiastic scientific community (Garret 2015 p.6)
Several factors can affect the actual results of an experiment. Among them are experimental and subject bias. Experimental bias concerns anything that misconstrues the experimenter's comprehension of the relationship between the dependent and independent variable (Feldman, 1999). Subject bias is the tendency of the subject to behave atypically. The double-blind procedure evades experimental and subject bias as the experimenter evaluates results unbiased as the experimenter is uninformed about whether the subject has received the actual treatment or the placebo and the subject will behave normally as they do not know if they have received the actual treatment or the pseudotreatment, the placebo. Therefore, the results and any distinctions among the control and experimental groups are clearly based on the independent variable and has to be the effect of the treatment. For example, in an experiment to evaluate a drug that encourages engagement in conversations, after administering the drugs to the experimental group and the placebo to the control group, the experimenters talk with participants and evaluate the conversation's degree of excellence which are not easy to assess. Thus, the experimenter might be biased and unintentionally give the participants in the experimental group better evaluations because they know that this group has been administered the real drug (Carlson & Buskit, 1997).
...p cells communicate with each other, and send emotion and thinking. Prozac blocks the GAPS of mood-influencing Serotonin, to raise levels of serotonin, regulating mood. Prozac doesn’t cure depression, but it is able to limit its symptoms and harm. The first six months of Prozac were the best months of Lauren’s life. She achieved happiness, a doctorate in psychology, a family, and happiness overall. However, as her body builds a resistance to the drug, the does need to increase. Laruen has had to raise her dose from 10 to 80 milligrams over her years of taking Prozac. Though her dosage has risen eight times, Laruen had few side effects. The best combination of treatment for her is of drugs and talk therapy. Talk therapy is able to change how the brain processes information. Since Lauren has left the hospital, she has tamed her depression and became a prized author.
In order to have a successful, reliable experiment you need sufficient data and evidence, reliable research, variables to test and a follow – up experiment. There are several types of variables you need to do an experiment. An independent variable is the manipulated experimental factor that is changed to see what the effects are. A dependent variable is the outcome. This factor can change in an experiment in reaction to the changes in the independent variable. An experimental group is the group of participants that are exposed to the change that the independent variable represents. The control group is participants who are treated in the same way as the experimental group except for the manipulated factor which is the independent variable (King 24). Proper data, evidence and research is also needed so the experiment turns out correctly and you know what you are testing. A follow – up experiment is not required, however it helps the validity of the conclusion of the experiment. Validity is “the soundness of the conclusions that a researcher draws from an experiment” (King 25). Conducting a follow – up experiment will help researchers and people alike see if the experiment worked properly, continues to help people and see how participants are doing after the experiment is over.
This lobe is also located in the cerebral hemisphere. The parietal lobe focuses on comprehension, language, reading. It also monitors all sensory comprehension. The parietal lobe has two parts. The sensory cortex and motor cortex. The sensory cortex, is located in the front part of the parietal lobe, it receives information from the spinal cord about the different positions of the various parts and how they move. This area of the brain affects area 's like sense of touch and relays if there is pain or pressure to different parts of the body. The motor cortex 's main function is to monitor and control movement of the body. It is located in the top, middle portion of the
The frontal lobe is a significant factor to the the brain. For example, this lobe focuses on decision making, problem solving, consciousness, and emotions. The frontal lobe is also known as the movement center. The forebrain makes the frontal lobe, which is the frontal section of the brain. And the frontal lobe is made up of the left hemisphere and right hemisphere. In the left hemisphere lies the speech area. Damage to this area ...
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
The human brain is the control center of the human body. It is the most important part of the body, because without a brain, none of us would be alive. In the brain, there are the cerebrum, the cerebellum, and the brain stem. The cerebrum holds memories, controls movement, and does problem solving and thinking. It is the biggest part of your brain. The cerebellum is underneath the cerebrum; it controls coordination and balance. The brain stem is the part closest to the neck. It controls breathing, heart rate, blood pressure, digestion, etc. (Alzheimer's Assosiation, 2011). The brain has two hemispheres as well as the three major sections; the right hemisphere and the left hemisphere. There is not exactly a “music area” in the brain.
An important part of an experiment is random assignment. If the participants for the study are randomly assigned to create two groups, and the researcher has enough participants in the study to have the desired “probabilistic equivalence” (Trochim & Donnelly, 2008, p. 187) then the researcher will feel a sense of confidence that the study will have internal validity in order to assess whether or not the treatment caused the outcome hypothesized. Well-c...
The frontal lobe comprises a third of the brain and it enables us to engage in higher cognitive functions such as planning and problem solving (Jonides & Smith, 1999). The frontal lobe is divided into 3 regions, the motor cortex, premotor cortex, and prefrontal cortex. The motor cortex is located in the precentral gyrus and directs fine motor coordination. The premotor cortex is involved in planning, organizing, and integrating body movements. The prefrontal is involved in executive functions, including short-term memory, working memory, decision making, and prioritizing behaviors (Wilson, 2003). Some of the frontal lobe disorders than can cause brain damage and behavioral changes are Huntington’s disease, infection, stroke, tourettes, dementia, epilepsy, Parkinson’s disease, tumors, closed head injury and traumatic brain injury (Chow, 2000).

The area at the front of the brain is the largest. Most of it is known as the cerebrum. It controls all of the movements that you have to think about, thought and memory.
The first method to be discussed and analysed are experimental methods. There is a variety of experimental methods including; laboratory, field and natural experiments. These methods are the most scientific method due to them being highly objective and systematic. In addition, this method is regarded as the most powerful research method used in psychology because of the potential to investigate the causes of events and therefore, identifying the cause and effect relationship. When carrying out an experiment the researcher intervenes directly in the situation being investigated. The researcher manipulates an independent variable (IV) in order to investigate whether there is a change in the dependent variable (DV). Any other variables that could have an
