Read through the following study description. Then, answer the questions below about this study. In this investigation, researchers examine how the color scheme of a website affects user engagement, measured by time spent on the site. Participants are recruited from an undergraduate psychology class and are shown the same website designed with two different color schemes: a high-contrast scheme (black text on white background) and a low-contrast scheme (gray text on a light gray background). Each participant experiences both versions of the website. During their interaction, the time each participant spends on the website is recorded. Additional factors such as the participant’s age, gender, and prior experience with similar websites are also documented to assess their impact on engagement levels. What should this study’s null and alternative hypotheses be? What are this study’s dependent and independent variables? What are some control variables and random variables that might come up in this study as designed? What are some potential confounding variables that might come up in this study as designed? Is this study best characterized as within-subjects or between-subjects, and why? This description of the study does not describe how the study will account for order effects. Last, briefly define order effects, then briefly describe how you might add to this study to control for order effects.

First, state what each letter in GOMS stands for and define each term. Second, create a simple GOMS model for the following situation: a user wants to turn off the light in their living room, which they can do by either controlling the lights with a wall switch or by interacting with it via a voice interface (like Alexa). Your GOMS model can be created in text outline form: just make sure to label what parts of the model correspond to the G, O, M, and S. Third, briefly describe how a cognitive task analysis model would be different from a GOMS model. Note that there is no one single right answer to this question. There are multiple possible models that could be created. Similarly, a cognitive task analysis model may differ in multiple ways; we are looking for you to demonstrate an understanding of what a cognitive task analysis model does differently.

Read through the following study description. Then, answer the questions below about this study. In this study, the effect of screen brightness on reading comprehension is explored. Participants are recruited from an undergraduate psychology class and are asked to read an article on a digital device under four different brightness settings: very low, low, medium, and high. The comprehension of the content is assessed through a quiz following each reading session. Each participant reads different articles of similar difficulty and length under each condition, though the specific articles are varied with different brightnesses. The study notes the age of participants and the type of device used (tablet or laptop) to monitor any potential influence on the results. What should this study’s null and alternative hypotheses be? What are this study’s dependent and independent variables? What are some control variables and random variables that might come up in this study as designed? What are some potential confounding variables that might come up in this study as designed? Is this study best characterized as within-subjects or between-subjects, and why? This description of the study does not describe how the study will account for order effects. Last, briefly define order effects, then briefly describe how you might add to this study to control for order effects.
