9.22 Do video game players have superior visual attentionskills? Researchers at Griffin University (Australia) con-ducted a study to determine whether video game playershave superior visual attention skills compared to non-videogame players (Journal of Articles in Support of the NullHypothesis, Vol. 6, 2009). Two groups of male psychol-ogy students-32 video game players (VGP group) and28 nonplayers (NVGP group)-were subjected to a seriesof visual attention tasks that included the attentional blinktest. A test for the difference between two means yieldedt = -.93 and p-value = .358. Consequently, the research-ers reported that "no statistically significant differences inthe mean test performances of the two groups were found."Summary statistics for the comparison are provided in thetable.

The paper "Deception and Design: The Impact of Communication Technology on Lying Behavior"+ describes an investigation into whether lying is less common in face-to-face communication than in other forms of communication such as phone conversations or e-mail. Participants in this study were 30 students in an upper-division communications course at Cornell University who received course credit for participation. Participants were asked to record all of their social interactions for a week, making note of any lies told. Based on data from these records, the authors of the paper concluded that students lie more often in phone conversations than in face-to-face conversations and more often in face-to-face conversations than in e-mail. Discuss the limitations of this study, commenting on the way the sample was selected and potential sources of bias. (Select all that apply.) O Students knew that they were surveying themselves as to the truthfulness of their interactions, which could have…
Phonics is an instructional method in which children are taught to connect sounds with letters or groups of letters. The article “Predictive Accuracy of Nonsense Word Fluency for English Language Learners” (M. Vanderwood, D. Linklater, and K. Healy, School Psychology Review, 2008:5–17) reports that in a sample of 134 English-learning students, the correlation between the score on a phonics test given in first grade and a reading comprehension given in third grade was r = 0.25. Can you conclude that there is a positive correlation between phonics test score and the reading comprehension score?
Behavioural Researchers view the internet and social media addiction as a disorder characterized by the excessive use of Facebook, Instagram, Snap chat, Twitter and other forms of social media such that it affects other aspects of life, including real-life relationships and academic achievement among those still in education. The paper "The Association between Aggressive Behaviors and Internet Addiction and Online Activities in Adolescents" (Journal of Adolescent Health [2009]: 598–605) reported on a study of more than 9400 adolescents. Each participant in the study was assessed using the Chen Internet Addiction Scale to determine if he or she suffered from Internet addiction. The following statements are based on the survey results: a) 51.8% of the study participants were female and 48.2% were male. b) 13.1% of females suffered from Internet addiction. c) 24.8% of the males suffered from Internet addiction Required i) What is the probability that an adolescent is addicted to the…
The paper "Portable Social Groups: Willingness to Communicate, Interpersonal Communication Gratifications, and Cell Phone Use among Young Adults"+ describes a study of young adult cell phone use patterns. (a) Comment on the following quote from the paper. Do you agree with the authors? Seven sections of an Introduction to Mass Communication course at a large southern university were surveyed in the spring and fall of 2003. The sample was chosen because it offered an excellent representation of the population under study-young adults. O No, the sample doesn't offer a good representation of young adults because it consisted only of students taking one particular course at one particular university. O No, the sample doesn't offer a good representation of young adults because it consisted of students from fewer than ten sections of the course. O Yes, the sample does offer a good representation of young adults because the university is large and students were sampled in both the spring and…
3. Does stress affect the recall ability of police witnesses? This issue was studied in an experiment that tested eyewitness memory a week after a nonstressful interrogation of a cooperative suspect and a stressful interrogation [the way of questioning] of an uncooperative suspect. The numbers of details recalled a week after the incident are summarized in the margin (based on data from "Eyewitness Memory of Police Trainees for Realistic Role Plays," by Yuille et al., Journal of Applied Psychology, Vol. 79, No. 6). Use 0.01 level of significance to test the claim in the article that stress decreased the amount recalled. Assume equal population variances. Nonstress Stress n1 = 40 X1 = 53.3 S1 = 11.6 n2 = 40 X2 = 45.3 S2 = 13.2 a. Claim (in symbolic form): Но: На: b. level of significance: test-statistic: tail of distribution:_ c.

In a study examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that a man's sense of humor had significant effect on how he was perceieved by woman. In the study, female college students were given brief descriptions of a po tential romantic partner and then rated the attractiveness of the male on a scale from 1 (low) to 7 (high). The fictitious male was described positively as being single , ambitious, and having good job prospects. In one dition, the description also said that he had a great sense of humor. The results showed that the description was rated significantly higher when "a sense of humor" was included. To further examine this effect, a researcher selected a sample of n = 16colle college males and asked them to read a brief description of a female and then rate the attractiveness of the woman in the description . The description had been used in previous research but was modified by adding a statement describing a good sense of humor…

Let population 1 be drivers of age 25-34 and let population 2 be drivers of age 50-59. An insurance company collects data on seat-belt use among drivers in a country. Of 1900 drivers 25-34 years old, 19% said that they buckle up, whereas 487 of 1800 drivers 50-59 years old said that they did. At the 10% significance level, do the data suggest that there is a difference in seat-belt use between drivers 25-34 years old and those Use the two-proportions z-test to conduct the required hypothesis test.

A sociologist wants to investigate the question, "Is there a relationship between texting during class and grade-point-average (GPA) among high school seniors in a large district?" Which study design is most appropriate? Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester, obtain each student’s GPA from the appropriate admissions and records office. Compare the GPA of students who routinely text during class to the GPA of students who do not text during class. Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester,…
The article “Developing a Tool to Measure the Factors Influencing Nurses' Enjoyment of Nursing” (L. Wilkes, M. Doull, et al., Journal of Clinical Nursing, 2016:1854–1860) reports that in a sample of 124 nurses, 54 said that a busy workload had a positive effect on their enjoyment of their job. Can you conclude that less than 45% of nurses feel that a busy workload has a positive effect on their enjoyment of their job?
