1. What is your research question?
Does the influence of direct or indirect exposure to misinformation have an effect on eyewitness memory and testimony? 2. What is your hypothesis or hypotheses? What is the null hypothesis? Hypothesis: If one is exposed to misinformation then it can lead to distortions in human memory for genuinely experienced events, as well as details of people, things, and places and eyewitness’s can be misled leading them to depict false information. Null Hypothesis: There is no affect to human memory, genuinely experienced events, nor details of people, things, and places, nor can eyewitness’s be misled leading them to depict false information when one is exposed to misinformation. 3. How many participants would you like to use and why? What are the inclusion characteristics, i.e., what must they have in order to be included in your study (for example, gender, diagnosis, age, personality traits, etc.)? Are there any exclusion characteristics, i.e. are there certain characteristics that would exclude them from being in your study? Does the sample need to be diverse? Why or why not? For this study I would use 120 participants, 60 male and 60 female. The group would be composed of persons from ages 18-55 years of age. I chose 120 participants so there was an even number of participants as well as split the gender evenly to represent both equally. They would be split into 3 age groups, ages 18-30, 31-44, and 45-55. This would place 40 people in each age group for the study. The age range is set from 18-55 to cover a wide range of adult age population. The race and ethnicity would be as evenly divided as possible among the group. One exclusion criterion would be the age range, persons under 18 and above 55 years of age could not participate. I would also want to exclude persons whom have experienced a similar traumatic experience as what was going to be used in the study to help prevent adverse reaction to the material. I believe my sample does need to be diverse in order to be able to generalize my study findings to the general adult population. I believe my sample does need to be diverse in order to be able to generalize my study findings to the general adult population. You cannot complete a study on only females and expect the results to be generalizable to males also. 4. What sampling technique will be used to collect your sample? What population does your sample generalize to? For this research study I would conduct convenience sampling. One reason I would choose this method is because of its ease and cost effectiveness. I would also choose this sampling technique because it would provide me the ability to choose how many participants I want as well as how I want to obtain them. I would continue to invite people to participate in the study until I had the desired amount as well as the diversity I needed for the study. While convenience sampling does not get great reviews for being able to generalize to a population I believe that if conducted properly within the parameters I have suggested above, the population the study should generalize to the adult population. There are no really specific inclusion or exclusion criteria that would limit the generalization to a specific group of people. I plan to split the gender as well as try to get the same percent of race/ethnicities included in the study and equally represented in each age group. This will help me better generalize the study to the general population. 5. What are the variables in your study? HINT: Refer back to your hypothesis or hypotheses. A few of the variables in my study would include, gender, age, race and ethnicity. The environment would be a variable as well as the person presenting the information. The information presented itself would be considered a variable as some will receive misinformation and some will not. The method in which the...
