1. What research question(s) does the study address?
2. What is Goldberg's rationale for the study? Was the study designed to contribute to theory? Do the results of the study contribute to theory? For both questions: If so, how? If not, why not?
3. What constructs does the study address? How are they operationalized?
4. What are the independent and dependent variables in the study?
5. Name the type of design the researchers used.
6. What internal and external validity threats did the researchers address in their design? How did they address them? Are there threats they did not address? If so how does the failure to address the threats affect the researchers' interpretations of their findings? Are Goldberg's conclusions convincing? Why or why not?

It looks like the authors of this study were interested in how the level of viewing of American children's television (ACTV) programming affects French-speaking and English-speaking children's awareness of toys and the number of children's cereals in the home. How does socioeconomic status moderate the relationship between the level of viewing ACTV programming by French-speaking and English-speaking children and their awareness of toys and the number of children's cereals in the home? Other questions are: what are the strengths and weaknesses of the experimental approach in studying the effects of advertising on children and are commercials more persuasive than a child's parents when it comes to food and toy preferences?

He states that his study merged both ...

Problems and Exercises I
(See the attached page)

A behavior therapist seeks to reduce the frequency of hitting behavior exhibited by a 6-year-old child in a classroom for emotionally disturbed children. The child frequently strikes other children and even the teacher. The therapist trains one of the teacher's aides to reward the child with small candy reinforcers when the child has not struck anyone for a period of 5 minutes. The experiment is conducted during two 1-hour sessions each weekday for a period of 4 weeks. An ABAB design is used, each week comprising a different stage. The results of this behavioral intervention are shown on the attachment page. Answer two question below:

1. Does visual inspection of the data obtained in this hypothetical study provide evidence for the effectiveness of the treatment? Why or why not?

2. Provide two suggestions for improving the quality of the evidence for the effectiveness of the treatment in this situation.
