- The efficacy of two kinds of cognitive-behavioral therapy (CBT) in relation to a clinical population werecompared. The therapies differed on the dimension of how wedded they were to the rational-emotivebehavioral therapy (REBT), a subtype of CBT that emphasizes a directive, confrontational approach toencourage a patient to recognize the irrationality of specific thought patterns. Forty adolescents at aninpatient clinic for treatment of self-destructive behaviors were randomly divided into two groups ofequal size, one of which received the less challenging type of CBT (Treatment A) and one of whichreceived the more challenging kind of CBT (Treatment B). All patients were treated by trained therapistsin one-on-one sessions for 1.5 hours per day (broken down into 45-minute sessions) for six weeks. Allparticipants were apprised that they were part of a study, all participants signed consent forms, and allwere told they would be informed of the results at its conclusion; participants…The efficacy of two kinds of cognitive-behavioral therapy (CBT) in relation to a clinical population werecompared.

A survey of 2645 consumers by DDB Needham Worldwide of Chicago for public relations agency Porter/Novelli showed that how a company handles a crisis when at fault is one of the top influences in consumer buying decisions, with 73% claiming it is an influence. Quality of product was the number one influence, with 96% of consumers stating that quality influences their buying decisions. How a company handles complaints was number two, with 85% of consumers reporting it as an influence in their buying decisions. Suppose a random sample of 1,100 consumers is taken and each is asked which of these three factors influence their buying decisions. Appendix A Statistical Tables a. What is the probability that more than 820 consumers claim that how a company handles a crisis when at fault is an influence in their buying decisions? b. What is the probability that fewer than 1,030 consumers claim that quality of product is an influence in their buying decisions? c.…
- In a research study, wherein the researcher wanted to know if people’s intelligence is perceived differently based on race, participants observed either a Caucasian, African American, or Asian American stimulus person giving a speech. All stimulus persons gave the same verbal speech. After observing this person, the participants had to rate the stimulus person’s level of intelligence on a scale of 1-10. The participants were separated by gender and their ratings were analyzed separately. How many possible interaction effects might the researcher find? Group of answer choices 3 0 1 2First, take a few minutes to think of at least four reasons why people willingly drank the Kool-Aid. You can use any resource you want (talk to other class members, use the internet, simply brainstorm, etc.). Second, think about one of those reasons and design a basic study that could test that notion. Think about an experimental group and a control group. What would the former get that the latter would not, and what would you look at in terms of responses from both groups?In a theoretical study, it was found that insomnia is associated with depression. It was also pointed out that stress could cause a person to have insomnia which is also related to having depression. The relationship between stress and insomnia is said to be: Bidirectional Indirectly causal Directly causal Noncausal Answer

Describe hypotheses that your study will test based on the scenario above.Ana is a Cognitive Psychologist and coffee lover. She decides to conduct a study investigating the impact of coffee on quiz comprehension. She randomly assigns participants to either the coffee group or the placebo group. Thirty minutes before the study begins, participants are given either a cup of coffee to drink (the caffeine group) or a cup of decaffeinated coffee to drink (the placebo group/no caffeine group) while they sit in the waiting room. Participants are not told whether they are drinking regular coffee or decaffeinated coffee. Following the thirty minutes, participants enter the lab and are asked to read a passage of text. After a short delay, participants are given a quiz to complete where they answer a series of 10 questions about the passage they read earlier. Ana is measuring the number of correct answers on the quiz. Unfortunately, one participant did not show up, so Ana was left with unequal sample sizes: Five participants in the placebo group and 4 participants in…The effect of aid is a subject of considerable academic and policy interest. In this question we examine the relationship between foreign aid and civil conflict using a recent paper by Crost et al. (2014) in the Philippines. The authors collect data on civil conflict related incidents at the municipality level as well as information on aid receipts at the municipality level. The conflict data was collected from the Philippine military and provides casualty counts (as well as the party responsible) by municipality. Aid in this context refers to a large anti-poverty program (the KALAHI-CIDSS) funded by the World Bank and run from 2003-2008. The program provided cash grants to municipalities to build infrastructure such as roads, water-systems, clinics and schools. The grants were fairly large and accounted for approximately 15% of the annual budget for the average municipality. (a) Let Yi denote the number of conflict casualties in municipality i in a given timeperiod after the…
- Would an observational study or an experiment be more appropriate for a medical research team that is trying to figure out if a new medicine is effective in treating migraines? Justify your response.As you read about each study, (a) classify the type of research that it reflects, and (b) identify the kinds of conclusions that might reasonably be drawn from the results. During their 8th- and 11th-grade school years, students in the Ranger School District take standardized achievement tests designed to assess their language and math skills. The superintendent receives a report showing how Ranger students compare with those in many other school districts across the nation. The superintendent discusses the results with the school principals. (a) Classify the research as one of the following: Quantitative/descriptive Quantitative/correlational Quantitative/experimental Quantitative/quasi-experimental Qualitative Mixed methods, and then (b) Identify one or more conclusions that might reasonably be drawn from this study and, if relevant, one or more conclusions that cannot be drawn from the studyTreatment for Cocaine AddictionCocaine addiction is very hard to break. Even among addicts trying hard to break the addiction, relapse is common. (A relapse is when a person trying to break out of the addiction fails and uses cocaine again.) A study is conducted to investigate the effectiveness of two drugs, desipramine and lithium, in the treatment of cocaine addiction. The subjects in the six-week study were cocaine addicts seeking treatment. The 72 subjects were randomly assigned to one of three groups (desipramine, lithium, or a placebo, with 24 subjects in each group) and the study was double-blind. Now we are able to consider all three groups together and test whether relapse rate differs by drug. Ten of the subjects taking desipramine relapsed, 18 of those taking lithium relapsed, and 20 of those taking the placebo relapsed. (a) Create a two-way table from the information given. Relapse No relapse Total Desipramine ? ? ? Lithium ? ? ? Placebo ? ? ? Total ? ? ?…
