Replication occurs when researchers apply an existing theory to new situations. This is often used to test the generalizability of different subjects. This subject group can include any type of variable such as age, race, location, and culture. The main goal of replication is to make sure previous results are valid, to determine the role of extraneous variables, to see how the theory is affected in new situations, and to inspire new research. Sometimes when replication is done results can change or become more vague. This is referred to as the decline effect. The decline effect does not mean the new results are better or that the previous results are wrong, it just means that the results occur less and less each time the experiment

The 2002 Afghanistan earthquake measured 5.9 on the Richter scale and killed 1,800 people. The 2001 western Washington earthquake measured 6.8 on the Richter scale and killed only one person. Can you imagine why the huge difference in the numbers of deaths? Hint: It has to do with construction materials.

If findings of a study can be continuously replicated and continue to produce converging patterns of similar findings, the study can therefore be further strengthened as a theory. In

A task force was formed to examine issues surrounding null hypothesis significance testing and the publication of research studies regarding these results. As a result of this task force, recommendations were made to revise statistical sections of the APA publication manual. But before these revisions were implemented, the Board of Scientific Affairs (BSA) recommended to initiate discussion of these changes, the task force publish an article in American Psychologist, hence this article. I will break down these suggestions in methods, results and discussion.

As each person embraces this area of research some disagreement is expected and the professionals use the opposition to help the program be successful. The disagreement helps them conduct more research. Although there is an increase in the need for evidence-base programs and practices, there are individuals who do not consider this area of research to be effective. This help the researcher address all the concerns and issues to make better choices and decisions in the future. They are advantages and disadvantages in using these programs.

The issues that needed to be overcome in research mainly revolve around the controversy of the research. One of the issues revealed in Bonk was the fact that the researches wanted to save their reputations. “Rather than risk being fired or ostracized by explaining

What are the implications of the authors’ findings? How can this information be applied in the future?

The replication crisis is a topic that has gained a fair amount of attention in the past years. It centers on the finding that numerous of the studies that have been conducted in the field of psychology cannot be replicated. Only recently a paper was published in Nature stating that less than half of the studies in psychology can be reproduced. It has been shown that this effect is not only applicable to studies of the psychological science, but also to medicine, technology, mathematical sciences, and many other disciplines in which research is being done.

\textbf{A positive feedback mechanism to maintain the polarity patch on the plasma membrane.} \textbf{(a)} Cdc42 exists as GTP-Cdc42 (ON state) or GDP-Cdc42 (OFF state). The GTP-Cdc42 indirectly converts neighboring GDP-CDC42 into GTP-Cdc42, which sets off a positive feedback loop. GTP-Cdc42 exists predominantly in the plasma membrane and diffuses very slowly while GDP-Cdc42 diffuses fast in the cytosol. Since one of the components (the scaffold protein Bem1) that goes into causing the positive feedback gets depleted, the patch of GTP-Cdc42 stops growing. \textbf{(b) and (c)} Actin cables deliver patches to dilute the polarity patch to make it wander.}

Ultraviolet light will affect the growth of basil. The plant setup with UV light will grow faster than the setup without UV-B light. To determine whether the experiment is successful I will measure the speed of growth, the number of seeds that germinate after a certain amount of days. Another important factor to consider prior to the laboratory experiment is whether the plant is sensitive to UV-B light or not. Sensitivity is most noticeable with regard to alterations in plant growth and development (Teramura 1983). UV-B radiation can damage the DNA structure of the plant and generate growth issues to the cells of Ocimum basilicum. However, the perception of low levels of UV-B by plants might actively promote survival because it may

Replication is repeating an experiment or study to determine whether the results can be duplicated, it is also a pattern over time like in the case of global warming. Replication importance to the field of science is usually underrated, as it attempts to replicate the study or experiment, thus copying another person or group’s research. Replication is not always done, but the study or experiment is meant to support the ability to repeat and get the same results, theoretically. So when replication has the same results of the study or experiment, this can confirm or bolster the previous or original works. However, if it does not have the same findings this can mean that there is a reliability issue, a confounding variable or question the validity

Having many measures in my study, with multiple readings and questionnaires, the order of the materials could have become a confound variable. For example, if I were to let participants read the manipulated trial transcript then complete the questionnaires, they could guess the purpose of the study (which is not juror decision making). I believe that besides one analyzing their study, having peer-reviews is very beneficial for founding out confounds that could occur in one’s study. For my peer review group, the suggestion of changing the ages was beneficial because not only have I haven’t thought about the issues with the previous ages (18, 23), but I understand why the new ages (17, 21) are more suitable. With the change of the ages at a more appropriate age, my chances of confounds have decreased and could decrease suspicions from participants regarding the age difference. This chapter has also made me aware of what experimental methods to lean on if I wanted to perform a study that was correlational. Overall, being able to critically analyze the study and make changes to avoid confounds is the best for experimental and correlational studies to remain internally valid for not only that current study, but future research as

After hours of deep research, one would be able to solve how statistics could be done incorrectly. My research was not extreme enough to find the true difference between replication problem and replication crisis, nevertheless, a replication crisis is when a scientist finds results of many scientific experiments that are usually impossible to replicate on subsequent investigation. While a replication problem in social sciences would be that the scientists are not interested in experiments that have already been replicated (Visser). Replications were not highly respected and were extremely unattractive. Also, another problem was the replication studies that have been carried out are usually demonstrated that they are not robust, which
