The aim of this report was to test the direct replicability of the IGT, and see whether it matched the original results. The original study showed that overall, healthy participants in the control category had a strong liking for the “good” decks. The error bars highlight that there is a difference in the frequency of selection between the ‘bad decks’ Deck A and B and the ‘good decks’ Deck C and D. This relationship is the focus of the experiment. As the error bars of the ‘good decks’ do not overlap with the error bars of the ‘bad decks’ the results suggest they are significantly different. Thus, the direct replication provides support for Bechara et al’s findings, namely the assumption that healthy individuals will select the “good” …show more content…
This creates conflict on which results to believe. A limitation of direct replication is confirmation bias, this is where a researcher searches for and or interprets data in a way to confirm their hypothesis. This involves illusory correlation, drawing links between data that are not real. However, research is mostly standardised and controlled thus, in most cases should not impact study replication. To conduct research multiple times is time intensive as well as expensive and thus unrealistic to implement. However, the publishing of research should be taken into more consideration. Practices such as peer review are imperative to prevent false information from being published. Published research has a profound impact on further research and it is difficult to discredit research once it has been published. Another difficulty with research across all disciplines of science is the file drawer problem. This is where research studies across all fields are more likely to be published if they produce positive findings than non-significant or negative ones. This has been suggested to affect the validity of research especially in meta-analysis which use these data. However, in contrast research from (Dan R Dalton, 2012) has shown that the file drawer effect ‘does not produce an inflation bias’ to the extent currently assumed. A dominating question in the replication crisis, is how should researchers tackle the
Imatinib is a Abl/c-kit/PDGFR inhibitor. Abl is a proto-oncogene related with chronic myelogenous leukemia. c-kit is a protein on the surface of various types of cells. PDGFR is a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family.
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
Throughout this course I have learned many things about research at an introductory level. Research is a critical part of all of our lives in many ways. God blesses each of us with a degree of common sense and we all learn from observing others even as babies, we learned behaviors and skills by observing our parents. Walking through experiences throughout life teach us a lot we need to know as well but sometimes we have to take a better approach when we need to learn about certain things. Many of us know that what works in some situations or with certain individuals doesn’t always work or is the safest option for another situation. Controlled and precisely organized study allows scientists to compare and examine contrasting methods and concepts, also helps them to discover various approaches and be able to learn from individual’s behaviors and experiences. I will act as the case study throughout this paper in order to observe what I have learned about.

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.

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.
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
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.
What are the implications of the authors’ findings? How can this information be applied in the future?
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
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
According to Baridam (2001), it is not enough to review literature without presenting the studies by topic and determining how each of these topics relates to the researcher’s own study. A systematic presentation of the literature forms the foundation of the study.
