APSY 211 Fall 2023 Instructor: Tianny Ocasio Writing Assignment #1 1. (2 points) Explain what anecdotal evidence is and why it is not a reliable guide to the truth, then provide an example of an argument that relies on anecdotal evidence. - Anecdotal evidence is when we give lots of weight to a statement through personal experience even if it has only occurred once to one person at one point in time. This is not a reliable guide to truth because it could be true for one person but nobody else, and there is no hard facts or backed-up evidence from professionals. One example of anecdotal evidence is to say “My friend eats a lot of sugar every single day their whole life and never gained weight” this would imply that that much sugar isn’t bad for people. 2. (3 points) Watch this video: https://www.youtube.com/watch?v=-X8Xfl0JdTQ then answer the following questions: (a) According to Karl Popper, why is a test seeking to falsify a scientific hypothesis better than one seeking to confirm it? (b) What are risky predictions and why are they essential to science according to Popper? - A) Test seeking to falsify a hypothesis is better than seeking to confirm it because the only genuine test is to prove your hypothesis wrong and to prove your hypothesis wrong is more valuable than proving it right. If your theory can’t be tested it doesn’t have much value. The more false information, the closer you are to the truth. To fail to falsify your theory, proves greater confidence that the theory is true. - B) Risky predictions are predictions that are very unlikely to occur unless the theory being tested was true. These are essential to Popper because if the risky predictions are true it will automatically prove the theory to be true which in the end can be more helpful than regular predictions. 3. Read the introduction (in other words, everything in between the “Abstract” and the section labeled “Experiment 1”) of the following article by Roediger and Karpicke (2006) on the testing effect , then answer each of the questions that follow. https://learninglab.psych.purdue.edu/downloads/2006/2006_Roediger_Karpicke_PsychSci.pdf (2 points) Describe the (a) research question , (b) hypothesis , and (c) prediction for this set of studies ( hint : refer back to the distinctions between these terms provided in Lecture 2). - Research question: how does the testing effect work under educationally relevant conditions, using prose materials and free-recall tests without feedback?
- Their hypothesis was that students will recall information more when they are tested on it. - In this study they predicted that performance on immediate retention tests would increase with the number of study opportunities (1 point) In lecture 2, we discussed where research questions come from and discussed several categories of possible origins for such questions. Which of the categories we discussed do you think this article best fits into and why ( note : you may mention several categories if you believe it fits into more than one). - I believe that this study is based on the origin of testing common sense because it is more of a wide belief that having multiple tests that we have to study for, helps us learn and recall more information. (1 point) In lecture 2, we also discussed the different types of research reports that exist. What type of research report is this article and why is this the case? - This is an empirical article because it is motivated by a research question and hypothesis. It describes the procedures of the experiment, materials and the results of the data. (2 points) Explain what the purpose of (a) informed consent and (b) debriefing are in psychological research. - Informed consent and debriefing are both important in psychological research because it informs the participants on what they will be doing in the study. Informed consent allows participants to be provided with knowledge required to make a decision about whether to voluntarily participate in research or not. Debriefing occurs at the end of the study and the experimenters explain to the participants the purpose of the study and why it was conducted.
