Lab Questions ● How do your individual results relate to cognitive theories or concepts? Hint: For ways to relate your answer to course concepts, see the lab introduction, the predicted results that come with your output, and the text. In relation to cognitive theories and concepts, my personal outcomes can be attributed to the fixation on the focal point and the green dot. This fixation resulted in both early and delayed responses during the trials. At times, my response was too premature as I became overly fixated on pressing the m key. I thought I could count out the seconds to press it. Conversely, there were instances where my response was excessively fast, driven by an anticipation for the stimulus. ● Why can you not react faster than 200ms? The lab's findings suggest that it is not possible to react in under 200ms due to a combination of cognitive and biomechanical limitations. Signal Detection Lab Data ● Insert your data in the table below. 4

Lab Questions ● How do your individual results relate to cognitive theories or concepts? Hint: For ways to relate your answer to course concepts, see the lab introduction, the predicted results that come with your output, and the text. When I first began this lab, I had no clue about what I was doing. However, I quickly grasped the concept and skillfully scanned the screen in search of the hidden line. As I progressed the lab, I noticed the fewer dots there were on screen, the clearer it to spot the 5

desired line, albeit I still missed a few. Surprisingly, there were occasions when I simply guessed, and surprisingly was correct on some instances. Initially, I believed that the more dots there were, the more evident the line would be, but I soon realized I was mistaken. ● What does d’ measure and how is it calculated? Why is this a helpful tool when measuring cognitive tasks? The d measurement is determined by the number of accurate responses in relation to the position of the line. This is an effective tool for assessing cognitive tasks as it indicates an individual's ability to detect signals. Visual Search Lab Data ● Insert your data in the table below.

Lab Questions ● How does the pattern of your individual results relate to that predicted for feature vs conjunction searches? Hint: For ways to relate your answer to course concepts, see the lab introduction, the predicted results that come with your output, and the text. I was intrigued by this lab as it focused on identifying a green circle amidst a black background. Initially, it was simple, but gradually, the lab introduced additional objects and more green shapes to obscure the target circle. I discovered that I possess excellent attention to detail and can easily spot an item buried among others. I had to be more mindful of the growing number of green objects and exert my sharp eye to locate the hidden green circle among the shapes. ● What is an example of a conjunction search in everyday life? For example, think about decisions that law enforcement officers, educators, medical professionals, or computer scientists make. This example can be personal or hypothetical. When I have the opportunity, I enjoy engaging in a few activities that I particularly like, both on my own and with my children. These activities not only provide me with personal enjoyment, but also offer my children the chance to enhance their mental capabilities by concentrating on identifying items. For instance, we often enjoy comparing two pictures and identifying the dissimilarities between them. Additionally, we occasionally engage in brain puzzles that involve searching for concealed objects within a picture. This exercise enables them to utilize their cognitive abilities to locate the hidden items within the image. Module Question 7

● Compare and contrast the differences in what your mind had to do to complete the tasks. To successfully fulfill the task, my mind undertook multiple activities. It prioritized the ongoing events in the lab and skillfully analyzed them, swiftly identifying differences and necessary objects. During the first laboratory session, my task mainly involved reacting to the presence of a green circle stimulus. Success in this lab relied heavily on my reaction time and ability to respond quickly. In the second lab, I had to search for a line within a pattern consisting of multiple dots. Similarly, the third lab required me to pinpoint a green circle among blue or green squares. Lab two and lab three exhibited significant similarities, with the only notable distinction being that lab two demanded more concentration compared to lab three, in my opinion. In lab two, I had to diligently search among a thousand dots to locate a straight line, which often resulted in me being deceived by finding eight or nine dots but failing to identify the tenth one.
