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.
Then there was a total of 30 Pixy Stix. The test subjects were each given 3 Pixy Stix and a paper that gave instructions and for them to record results. First, the test subjects recorded their mood 1-5. Next, they ate the Pixy Stix and waited 30 minutes. During those 30 minutes the test subjects did not consume any food. After the 30 minutes was up, the test subjects recorded their mood. The test subjects did this a total of 3 times to complete the 3 trials needed for the experimental group. For the control group, the same 10 test subjects were used. They recorded their mood 1-5 and waited 30 minutes. During this 30 minutes they did not consume anything at all. After the 30 minutes was up they, recorded their mood
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.
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...
The Frontal Lobe: Is the anterior part of cerebral hemisphere of the cerebrum of the brain, extending back to region called the central sulcus is a deep cleft on the upper surface of the brain. The frontal lobe is for intelligence which carries out high mental procedures such as thinking, judgment making, and forecasting. The human body uses their frontal lobe nearly every day. The frontal lobe
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.
The brain has many functions in which it helps process and understands information. One aspect of the brain is its memory. Memory is there so information can be used to understand what is happening around someone. The function of memory is somewhat of an enigma to many scientists. How does the brain store and retrieve such information and at such high speeds? Although it is hard to conceive the actual machine working behind memory scientist have been able to figure out the physiology behind this process. The brain is composed of millions of neurons. Communication between these neurons is by using nerve impulses from the axon of one neuron to the dendrites of another. This is called a synapse. All impulses are transmitted by a chemical substance, which is called a neurotransmitter. Scientists have not been able to explain the actual processes that occur within memory. They cannot explain why people can remember something's and not other or why some learning strategies are better then others. It turns into more of a guessing game using analogies to explain what happens. Memory has been compared to the way " we rummage our house for a lost object." That is the way the brain works in terms of memory. The confusing part is how one can store it retrieving it and even use it to decipher harder more complex problems. In one early theory memory is broken down into two areas. These areas are primary memory and secondary memory. Primary memory is said to not have to be retrieved. It was never lost and it is what is seen in present time. Secondary memory is a place where everything can be stored, but the difference is secondary memory has to be retrieved and cannot be used like primary me...

...the data did not involve member checking thus reducing its robustness and enable to exclude researcher’s bias. Although a constant comparative method was evident in the discussion which improved the plausibility of the final findings. Themes identified were well corroborated but not declared was anytime a point of theoretical saturation Thus, the published report was found to be particularly strong in the area of believability and dependability; less strong in the area of transferability; and is weak in the area of credibility and confirmability, although, editorial limitations can be a barrier in providing a detailed account (Craig & Smyth, 2007; Ryan, Coughlan, & Cronin, 2007).
The study is usually described as an experiment with the independent variable being, the condition the participants are ...
Most of the body’s functions such as, thinking, emotions, memories and so forth are controlled by the brain. It serves as a central nervous system in the human body. The mind is the intellect/consciousness that originates in the human brain and manifests itself in emotions, thoughts, perceptions and so forth. This means that the brain is the key interpreter of the mind’s content. Jackson and Nagel seem to resist identifying what we call “mental events” with brain events, for different reasons, while J.J.C. Smart takes the opposing view.
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
It contains the primary motor cortex and the prefrontal cortex, which extend from the central sulcus to the anterior of the brain. The posterior part of the frontal lobe is the precentral gyrus which is specialized in the control of fine movements. The very most anterior portion of the frontal lobe is the prefrontal cortex. The neurons in this area have up to sixteen times as many dendritic spines as neurons in the occipital lobe or primary visual cortex. As a result, the prefrontal cortex is able to integrate a great deal of information (Kalat, 2004).
This lobe is also located in the cerebral hemisphere. The parietal lobe is focused on comprehension, language, reading. It also monitors all sensory comprehension. The pariental lobe has two parts. The sensory cortex and motor cortex. The sensory cortex, is located in the front part of the parietal lobe, it recieves information from the spinal cord about the different positions of 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
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...
