Dries was investigating whether humans process information in an active or apassive way. He gave participants a paragraph where the words had the correct firstand last letter but all the rest in the middle were jumbled. Participants had to saywhether they could read the paragraph or not.Dries considered information processing to be active if the participants could readthe paragraph but passive if they could not read the paragraph.The results are shown in Table 2.ConditionParticipants who could readthe paragraphParticipants who could notread the paragraphTable 2Percentage (%)98%2%Explain one conclusion that could be made from Table 2 regarding how humansprocess information.

Dr. Moas is interested in examining how environmental cues affect memory. She asks 15 students to study 10 obscure words for a vocabulary exam. All students take the final vocabulary exam in Classroom A. She randomly assigns participants to one of three locations to study for the exam: the same classroom (Classroom A), a different classroom (Classroom B), or a completely separate location, the school gym. Then, she records the number of vocabulary words that each student correctly defines on the exam. The data is as follows: Participant Study Location Vocabulary Words Answered Correctly 1 Same Classroom 9 2 Same Classroom 8 3 Same Classroom 10 4 Same Classroom 8 5 Same Classroom 9 6 Different Classroom 9 7 Different Classroom 8 8 Different Classroom 7 9 Different Classroom 8 10 Different Classroom 7 11 School Gym 6 12 School Gym 7 13 School Gym 5 14 School Gym 6…

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” 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 Speed Smashed into Hit n=15M=40.8SS=510 n=15M=34.9SS=414 Use an independent-measures t test with α=.05 to determine whether there is a significant difference between the two conditions and compute r2 to measure effect size. Now, increase the variability by doubling the two SS values to…
A psychologist wants to test the influence of color on object recognition in 4-year olds. She recruits 25 children and shows them two sets of pictures of everyday objects (variable = picture type), has the children name them, and measures the time it takes (variable = reaction time). She shows the children a color set of pictures first and then shows them a black and white set of pictures. a) What is the independent variable? b) What is the dependent variable? c) What is the second independent variable? d) What is the second dependent variable? e) Is "picture type" a within-subjects or between-subjects variable? f) What scale of measurement is reaction time? g) What scale of measurement is picture type? h) The order of presentation of the picture sets is what kind of variable?
A study was conducted to evaluate how foreign language learning is influenced by instruction methods- immersion vs. memorization. The study used two groups of native English speakers. One group (Group1, with n=9 participants) participated in a course focusing on immersion, while the second group (Group2, with n=10 participants) participated in a course focusing on memorizing words and grammar. Both groups took a language test immediately following the course and their test scores were compared. Group1 had a mean exam score of 70 and the sum of squares SS =72, while Group 2 had a mean exam score of 86 and the sum of squares SS =90. The researcher wants to know if there is a significant difference between the mean exam scores of the two groups. An alpha level of .05 was set by the researcher. What type of t-test should you do? related-samples independent-samples Is the hypothesis directional or non-directional? State the null and alternative hypotheses in…

Hospital administrators at a local hospital are interested in quality of care. As such, they ask a random sample of patients that have used the hospital's health care services to fill out a questionnaire. The questionnaire has questions about the patient's worry (negative, positive), the hospital staff's communication skills (low, medium, high), and satisfaction with medical care. The administrators are interested in how patient's worry and their assessment of the hospital staff's communication impact their satisfaction with medical care. The survey data are below. What can the administrators conclude with an α of 0.01? Communication Worry low med high negative 76868 54545 67495 positive 86677 78687 78666 A) Input the appropriate value(s) to make a decision about H0.Worry: p-value = Communication: p-value = Interaction: p-value = B) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).Worry: η2 = Communication: η2 =…
A report described teens' attitudes about traditional media, such as TV, movies, and newspapers. In a representative sample of American teenage girls, 42% said newspapers were boring. In a representative sample of American teenage boys, 45% said newspapers were boring. Sample sizes were not given in the report. A button hyperlink to the SALT program that reads: Use SALT. (a) Suppose that the percentages reported had been based on a sample of 50 girls and 40 boys. Is there convincing evidence that the proportion of those who think that newspapers are boring is different for teenage girls and boys? Carry out a hypothesis test using ? = 0.05. (Use pgirls − pboys.) Find the test statistic. (Round your answer to two decimal places.) z = Find the P-value. (Round your answer to four decimal places.) P-value = State your conclusion. Reject H0. We do not have convincing evidence that the proportion of girls who say that newspapers are boring is different from the proportion of boys who…
