You’ve been working with a graduate student in the lab to investigate the properties of two different drugs and how they affect memory behavior in a model of Alzheimer’s Disease in rats. Your faculty advisor (principal investigator or PI) wants an update on the project, and the graduate student is sick that day so now you have to explain the results of your study to the PI. You pull up the slides that the graduate student created for the presentation and explain the figures she created. Describe how you would explain the results in Figure 1 and Figure 2. Part A, Figure 1: In your description, include (i) what this graph is called, (ii) what you can infer from the x- and y-axes, (iii) and what your overall conclusions are for the 2 drugs in comparison to each other and for the overall research question. Part B, Figure 2: You realize that the graduate student forgot to label which drug was represented by each example trace of the Morris Water Maze results in Figure 2. In your description to the PI, include (i) which drug label should be over each image based on the results in Figure 1. Your PI asks you to consider limitations to your study and you deliver your response in the framework of the principles of behavior. State how the experiment and measurements from your study could be influenced by the materiality (context), agency (purpose), and historicity (experience). In your answer, please be sure to iii) define each principle and iv) describe one way in which each principle could apply to this experimental design.
