Experimental and Quasi-Experimental Design
There are basically two main categories of measuring variables with a sample of participants or subjects: experimental and quasi-experimental. According to (Hopkins, 2008), research studies can be carried out using body tissues, cells, animals or humans. The researcher is looking for a relationship between the variables, and this can be accomplished using statistics, relative frequencies, and/or correlations (Hopkins, 2008). One can accomplish this by simply observing without influencing, manipulating, or controlling the environment or interaction. One can observe and explore one subject, or one can compare one subject with another (Hopkins, 2008).
Experimental Study
The goal of this study is to discover whether the intervention of using relaxing music has can impact the emotional state. The hypothesis of this study asks to what extent does listening or not listening to music before a test decrease test-taking anxiety in middle school students? The second hypothesis is to what extent does listening or not listening to music increase test scores in middle school students?
If the hypotheses are supported, then the students will not only state a decrease in physical and emotional symptoms of anxiety, but will score higher than the average of their prior three tests. This means that a decrease in anxiety will occur after the intervention, and a decrease in anxiety will produce a higher score. Having one variable decrease and the other increase is known as a negative correlation (Cozby and Bates, 2012). This means that there is a relationship between the two variables. Of course, this must be not only proven by statistical ev...

Usually forensic psychology is defined as the intersection of psychology and the law. Yet, in many cases not all individuals working within criminological psychology are not necessarily "forensic psychologists." These individuals might actually be clinical psychologists, or adolescent psychologists, neurologists or psy...
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.

CHAPTER II METHODS Participants Forty members of a Research Methods in Psychology course at the University of Missouri – St. Louis (UMSL) served as participants in this examination. These participants were recruited within their respective laboratory periods. No money was awarded to the subjects for their participation.

Another commonality of all three of these studies is the method which is: Empirical Studies. The definition of Empirical Studies is a study in which data is collected by direct or indirect experiences and/or observations (Bruns1).

Since the inception of this niche in psychology, there has been a greater appreciation for the use of police psychological services. Now almost every police department has a separate psychology department with a number of psychologists working with its other employees. This specialized subset of psychology delivers a number of services to its employees, from assessing qualified applicants, counseling, to suspect profiling and providing expertise during hostage situations. The field has grown tremendously, especially over the last 40 years and has developed into its own sub-specialty with its own dedicated research, journals and professional organizations. During that time, there have been great strides made in developing this relationship betwe...
Experimental designs are viewed as the most accurate, and most demanding of research designs, requiring strict attention to rules and procedures. Researchers use these research designs to manipulate and control testing procedures as a way to understand a cause and effect relationship. Commonly, independent variables are manipulated to judge or decide their effect on a dependent variable (Trochim & Donnelly, 2008).
In ancient, it is very pervasive belief that music can actually produce emotion to the listeners. Music’s beneficial effects on mental health have been known for thousands of years. Ancient philosophers from Plato to Confucius and the kings of Israel sang the praises of music and used it to help soothe emotional stress. Many people say that they listen to music because it can make them feel comfortable, relax, happy and so on. In line with this emotion regulate through music is often considered as one of the most important function of music. The impact of music to our emotion is that creates awareness of our current emotional state, in contrary, music can evoke our feeling through its structural properties. Emotions are processed
