(Additional information for Questions 24 and 25). Theory of mind (ToM) is known as a social cognitive ability in which children are able to recognize that other's have different desit beliefs, and emotions that are different from oneself. Child on the autism spectrum tend to acquire this ability later in development than typically developing children. The psychologists wanted to examine if children on different levels of the spectrum vary on whether they are ab to pass or fail a theory of mind task. After testing the 100 children they sampled on a Theory mind task, here's what they found using the three level of AS they identified in the previous section of this section: Pass ToM Fail ToM

In 1974, Loftus and Palmer conducted a classic study demonstrating how the language used to ask a question can influence eyewitness memory. In the study, college students watched a film of an automobile accident and then were asked questions about what they saw. One group was asked, “About how fast were the cars going when they smashed into each other?” Another group was asked the same question except the verb was changed to “hit” instead of “smashed into.” The “smashed into” the group reported significantly higher estimates of speed than the “hit” group. Suppose a researcher repeats this study with a sample of today’s college students and obtains the following results. Estimated SpeedSmashed Into Hitn = 16 n = 16M = 40.8 M = 34.0SS = 510 SS = 414 For this problem, complete the four stages of hypothesis testing to determine whether the assumption of homogeneity of variance is met. (Note: This problem is NOT asking you to conduct an independent-samples t-test.) Use a nondirectional…

Section 11.2 Question #4 The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? View the table Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Polygraph test indicated that the subject lied. 9 48 Polygraph test indicated that the subject did not lie. 30 12 Determine the test statistic. χ2= _________ (Round to three decimal places as needed.) Determine the P-value of the test statistic. P-value= ___________ (Round to four decimal places as needed.)
A drug trial had 161 participants. A survey was done to gather information about the participants' experiences with side effects. The table below gives the results for two possible side effects. Number of participants Had drowsiness 84 Had nausea 67 Had both drowsiness and nausea 39 Construct a Venn diagram illustrating these results. Then answer the questions.
A group of people use an app to track their work outs in the gym everyday. The workouts can be categorized as Strenuous, Moderate, or Light. When the data from the app was reviewed, the following observation was made: Of the people who work out strenuously on a particular day, 40% will work out strenuously the next day and 60% will work out moderately. Of the people who work out moderately on a particular day, 50% will work out strenuously the next day and 50% will work out lightly. Of the people working out lightly on a particular day, 30% will work out strenuously on the next day, 20% will work out moderately, and 50% lightly. (a) Set up the 3 x 3 transition matrix with rows and columns labelled S , M, and L. (b) Suppose that on a particular Monday, 80% work out strenuously, 10% moderately, and 10% lightly. What will the distribution be on Wednesday? (You can use a calculator for the matrix multiplication.) (c) Find the stable distribution algebraically.
We discuss how to test for an association between two categorical variables in Section 6.8. A marine research team records the number of fish from 3 species that they find at different depth categories in the ocean. They are interested in assessing whether or not there is a relationship between the depth category (close to surface, mid-level, ocean floor) and the fish species found (species A, species B, species C). A two-way table showing the classification of a sample of 150 observations is given below. If the variables for the ocean depth category and the species are independent, how would you calculate the expected number of fish that are at the mid-level and from species C? Expected number =

A psychologist wanta to determine the effect of relaxing music on a person's reaction to a stressful event. Participants were randomly assigned to one of three groups. A participant was brought into a room with no windows and only one door. In the background, either soft classical music, or no music at all was playing. After a set amount of time, a fire alarm went off, and smoke started to come from under the door. A hidden video camera records the participants behavior that is later scored by the experimenter for level of panic from 0-100. Which statistical test would be best to determine if there is a significant difference between groups? One sample t test Dependent samples t test Independent t test ANOVA
Craik & Tulving ran an experiment to determine how depth of processing during study affects memory. In the study phase, 12 participants made judgments about words. In one block of trials (the visual condition) they indicated whether the words were written in upper case or lower case; in another block of trials (the auditory condition) they indicated whether the words contained an "ee" sound; in another block of trials (the meaning condition) they indicated whether the meaning of the words was pleasant or unpleasant. There were 12 words in each block. After completing the study phase, participants were asked to write down all the words they could remember. Here are the data: Mean Visual 3.5 Auditory 4.5 Meaning 6.0 Standard Deviation 1.5 1.6 1.9 Compared to the within-subjects design, the between-subjects design (select all that apply) Oa.
