Georgia State Your Brain on Dopamine Science of Motivation Article Discussion Discussion post
Post something to the discussion board related to the content we are exploring this week. For each post, be succinct, using no more than 75 words. Also feel free to explore the features of Yellowdig, such as the ability to embed videos and pictures, create polls, use hashtags, like or love a post, and so on.
Here are some ideas for your pin (post) to get you started:
Find a short video or article about motivation and the brain. Share the link to your source and a short summary of the source. Include why you found the resource helpful to your understanding.
Discuss an area of motivation and the regulation of internal states in Chapter 6 that stood out to you. Why was this information important to you? Can you see it affecting your personal or professional life?
Find an article about emotions and the brain in the popular press (such as The New York Times, CNN, Psychology Today). Share a link to your source and a short summary of the source. Discuss why this made the news and why it is important.
Discuss an area of emotion and health in Chapter 8 that stood out to you. Why did this catch your attention? Can you see this information affecting your personal or professional life?
Find a video about an aspect of emotions and the brain. Share the link and a short summary. Also, share what stood out to you the most or surprised you.
Find a scholarly, peer-reviewed article showing empirical research in an area of neuroscience. If you want to get a head start on your Unit 5 assignment, you can read the assignment instructions in Unit 5 and chose an article that would apply. Post a link to the article and a brief summary of the research methods used and the author’s conclusions.
u04a1 – Normal Curve, z Scores, Probability, and Binomial Distribution
Complete the following problems within theWord document (do not submit other files).Show your work for problem sets that require calculations. Ensure your answer to each problem is clearly visible. (You may want to highlight your answer or use a different font color to set it apart.)
Submit the document to your instructor by Sunday, 11:59 p.m. central time.
Problem Set 4.1: Mutually Exclusive Outcomes
• Criterion: Determine if events are mutually exclusive.
• Instruction: Consider the following events. If the outcomes are mutually exclusive, type yes. If the outcomes are not mutually exclusive, type no.
a. Turning right or turning left.
b. Studying Spanish or studying Italian.
c. Flipping heads on a coin or flipping tails on a coin.
d. Drawing an eight from a deck of cards or drawing a king from a deck of cards.
e. Riding a bike or wearing a hat.
Problem Set 4.2: Probabilities: Dichotomous Events
• Criterion:Calculate probability for a dichotomous event.
• Data: Jane has flipped a coin 10 times, and each time it has landed on heads.
• Instruction:Answer the following:
o What is the probability that Jane’s11thflip will land on heads as well?
Problem Set 4.3: Calcuations on z and the Unit Normal Table
• Criterion: Calculate percentages based on z scores and the normal curve.
• Data: For homes that were sold in the past year, the average number of days on the market (DOM) was 266 days. During this time, DOM was normally distributed, with a standard deviation of 12 days. The Carmichaels sold their house in 245 days.
• Instruction: Using the unit normal table, answer what percentage of homeowners:
a. Sold their home at the same point or earlier than the Carmichaels?
b. Sold their home at a later point than the Carmichaels?
c. Sold their home between 245 days and the average DOM?
(Assignment continues on next page.)
Problem Set 4.4: Calculating z Scores in SPSS
• Criterion: Calculate z scores using SPSS.
• Data: The following is a list of the number of goals scored over a 10-game soccer season:
2, 1, 5, 6, 0, 0, 3, 8, 1, 2.
• Instructions: Complete the following steps:
a. Enter the data into SPSS using the variable name Goals.
b. In the Toolbar, click Analyze, select Descriptive Statistics, and then select Descriptives.
c. SelectGoals and then click Arrow to send data over to the right side of the table. Check the box Save Standardized Values as Variables.
d. Select Options, check the boxes Mean and Standard Deviation, and then deselect all other boxes. Click Continue.
e. Click OK and then copy and paste the descriptive statistics table below.
f. Go to the Data View in SPSS.You will see that the z scores have been added to the file. Paste a screenshot of the Data View, showing the z scores, into the Word document.
g. Which number of goals is closest to the z score of 0?
Problem Set 4.5: Area and the Normal Curve
• Criterion: Calculate z scores and find the area under a normal curve.
• Data: The mean combined SAT score for a sample ofhigh school seniors is 1500 and the standard deviation is 250.
• Instructions: Answer the following:
a. What percentage of students scored below 1000?
b. What percentage of students scored above 1750?
