Lab Report for Lab 3 & 4
Each report needs at least 2 pages

Lab Report 3 – Highly Selective Visual Disorders For this lab activity, you will watch a movie about 4 people who, due to brain damage from car accidents or strokes, have highly selective visual disorders. Also, you will read an article about a case study of a 5-year old boy who has had prosopagnosia from birth. The video is called “The Mind’s Eye” and can be found at the following web link: https://www.dailymotion.com/video/x17ilh8 . The article is found on the class Canvas site, and it is labeled “prosopagnosia article.” Write up your lab report in a numbered list, answering the questions below. Note: The instructor may choose to grade only a subset of the questions, rather than all the questions. length: Your lab report must be typed, about 2-3 pages (double-spaced). due: April 16th by 10:00pm. Unlike the previous lab reports, you will submit Lab Report 3 in Canvas. It will also be checked with turnitin.com Questions on movie: 1. Gisela Leopold is unable to see motion after suffering a stroke. Briefly summarize how her disorder affects her life. Then, describe the test that was done on her in the movie and what was unusual about her responses/behavior in the test. 2. Lincoln Holmes is prosopagnosic after being in a car accident. Briefly summarize how his disorder affects his life. Then, describe the test that was done on him in the movie and what was unusual about his responses/behavior in the test. 3. Kevin Chappell is unable to recognize objects after being in a car accident. Describe how Kevin deals with his inability to recognize objects in his everyday life (i.e., describe the strategy Kevin uses to attempt to identify what objects are.) Then, describe the test that was done on him in the movie and what was unusual about his responses/behavior in the test. 4. Peggy Palmer “neglects” the left side of space after suffering a stroke. Describe the test that was done on her in the movie and what was unusual about her responses/behavior in the test. 5. Throughout the movie, the announcer brings up the idea that the brain “constructs” what we see. Discuss evidence in favor of this theory, from the movie. That is, discuss some experimental results shown in the movie that support this theory, and/or discuss why the visual disorders these 4 people have support this theory. Questions on article: 6. How was it determined that TA’s overt recognition of familiar faces is impaired? (that is, briefly describe the experiment done on this topic, and its results) (this question may count double the value of the other questions) 7. Did TA show any evidence that he had recognized the identity of the familiar faces in some (maybe unconscious) form? If so, what was this evidence? (that is, briefly describe the experiment done on this topic, and its results) 8. Was TA’s recognition of objects (other than faces) impaired? How was this determined? (that is, briefly describe the experiment done on this topic, and its results) 9. Was TA’s recognition of emotional facial expressions impaired? How was this determined? (that is, briefly describe the experiment done on this topic, and its results) Instructions and Data Table for Lab Activity 4 (Visual Search) Step 1: Get ready • Go to the webpage: https://oup-arc.com/access/sensation-and-perception-5e-student-resources • On the left side, select “Chapter 07” • Click on “Sensation & Perception 5e Activity 7.2 - Visual Search” • Read Introduction page Step 2: Feature Search • press “Feature Search” • read instructions • after doing each trial it will show results on right side • do trials until you have at least 20 trials in both the “5 item” and the “17 item” columns • once you have done all trials, copy data into table • then press “Typical Feature Search Results” • then press “Conjunction Search” Step 3: Conjunction Search • read instructions • do trials until you have at least 20 trials in both the “5 item” and the “17 item” columns • once you have done all trials, copy data into table • then press “Typical Conjunction Search Results” • then press “Serial Search” Step 4: Serial Search • read instructions • do trials until you have at least 20 trials in both the “5 item” and the “17 item” columns • once you have done all trials, copy data into table • then press “Typical Serial Search Results” • then press “Dynamic Search” Step 5: Dynamic Search • read instructions • do trials until you have at least 20 trials in both the “5 item” and the “17 item” columns • once you have done all trials, copy data into table • then press “Typical Dynamic Search Results” 5 items 17 items Task Trials Avg. RT (ms) Trials Avg. RT (ms) Feature search Conjunction search Serial search Dynamic search Lab Report 4 Prompt (Visual Search) For this lab activity, we will do an experiment testing several types of visual searches. This experiment will examine how the speed of search is affected by the type of search and the number of items being searched. Write up your lab report in a numbered list, answering the questions below. Note: The instructor may choose to grade only a subset of the questions, rather than all the questions. length: The written part of your lab report must be typed, about 2½ pages (double-spaced). due: Thurs. April 16 by 10:00pm. You will submit Lab Report 5 in Canvas. Go to the Assignments section and find Lab Report 5. It will also be checked with turnitin.com, any forms of plagiarism such as information from coursehero and chegg will receive an F for the class. Note: You do not need to discuss search “slopes” in any of your answers. Introduction 1. What does it mean to do a “parallel search process”? 2. What does it mean to do a “serial search process”? Method 3. Describe what you did in the Feature Search condition of the experiment. Be sure to include a description of what the target and distractors looked like, how many items there were, how many trials there were, etc. 4. Describe what the target and distractors looked like in the Conjunction Search condition. 5. Describe exactly what the target and distractors looked like in the Serial Search condition. 6. Describe what occurred in the Dynamic Search condition of the experiment. Be sure to include a description of what the target and distractors looked like. Results 7. Look at your data table at the bottom of your “Instructions and Data Table for Lab Activity 5” handout, where you wrote in your data. Now create a similar table in your assignment document, containing your data. The table should not be in a separate document, it should be in your answer #7 of your LR 5 document that you are submitting on Canvas. Please let me know if you have any questions about this! Discussion 8. In the Feature Search condition of the experiment, were your data (i.e., results) consistent with the idea that this search is done as a “parallel search process”? Explain why or why not. 9. In the Conjunction Search and Serial Search conditions of the experiment, were your data (i.e., results) consistent with the idea that each of these two searches are done as “serial search processes”? Explain why or why not. 10. Explain why searches like the one in the Conjunction Search condition of this experiment usually are done as a “serial search process.” 11. Why would it be difficult to do the Dynamic Search condition as a “serial search process”?
