Scientific Method

Scientific Method -A process of conducting experiments to test if a hypothesis is true or false. 

The scientific method is generally performed with 6 steps:

1) Purpose/Question- Ask a question.

2)Research- Conduct background research. Interview experts on a topic. The more you know about a subject, the easier it will be to conduct your investigation.

3) Hypothesis - Propose a hypothesis. Usually, a hypothesis is written in terms of cause and effect.

4) Experiment- Design and perform an experiment to test your hypothesis. An experiment has an independent and dependent variable.

5) Data/Analysis - Record observations and analyze the meaning of the data. Often, you'll prepare a table or graph of the data. Once you have the data, you may need to perform a mathematical analysis to support or refute your hypothesis.

6) Conclusion- Conclude whether to accept or reject your hypothesis. There is no right or wrong outcome to an experiment. The results may be compiled into a lab report or formally submitted as a paper.


In an experiment there are Three Variables:

1-Controlled Variables: You can have as many controlled variables as you like. These are parts of the experiment that you try to keep constant throughout an experiment so that they won't interfere with your test. Writing down controlled variables is a good idea because it helps make your experiment reproducible, which is important in science! If you have trouble duplicating results from one experiment to another, there may be a controlled variable that you missed.

2-Independent Variable: This is the variable you control.

3-Dependent Variable: This is the variable you measure. It is called the dependent variable because it depends on the independent variable.

Psychology study on Fear Appeal

"Sixty years of fear appeal research: Current state of the evidence" This journal study gives an in-depth study of fear appeal theory including how it works in marketing and health settings, theories that contradict, and how to assess it effectively.  Abstract:  "Following a brief overview of the use of fear arousal in health education practice and the structure of effective fear appeals according to two main theoretical frameworks—protection motivation theory and the extended parallel process model—the findings of six meta-analytic studies in the effectiveness of fear appeals are summarized." "Threatening health messages are popular in health education design. For example, the introduction of health warnings on cigarette packages in 2002 was accompanied by wide-scale media attention on television, radio and in newspapers throughout Europe. Soon after the introduction of these messages, national polls were presented that suggested that people smoked less becaus...

Covid Stress influencing Media Addiction

 I found a study done in Beijing, China that could greatly support my research into Media Dependency. It surveyed over 200 college students and found a direct correlation between Covid-19 stress and an increase in social media addiction in individuals.  Below are excerpts I am especially interested in: "Due to policies to limit the spread of the virus, such as the “shelter-in-place” order (1), people, willing or not, are undergoing a transition from offline to online activities (2). In addition to remote work or remote learning, many people spent increased time on social media (SM), such as Facebook and Twitter, which could satisfy their need for disaster-related information, entertainment as well as interpersonal communication (3, 4)" "The present study examined the relationship between COVID-19 stress, active use, SM flow, and addictive SMU in a sample of Chinese college students. Consistent with Hypothesis 1a, COVID-19 related stress was associated with a greater tend...

Risk Perception Theory

Risk Compensation/Risk Homeostasis Theory is According to Campbell Institute "people tend to take more risks when they feel a greater sense of security. In other words, individuals adjust their level of risk-taking behavior depending on the safety measures that are in place (Wilde, 1994)." I find this theory very interesting because it can easily be applied to the Netflix series Squid Games, where hundreds of people willingly fight fight for the death for a chance to become a billionaire. Even though it's a fictional show, it perfectly fits the framework of this theory's risk-reward parameters.  Risk Compensation is a subsidiary of Risk Perception Theory- which simply means the study of one's ability to accept or discern a risk. https://www.thecampbellinstitute.org/wp-content/uploads/2017/05/Campbell-Institute-Risk-Perception-WP.pdf
