For exercises 12.51-12.53, evaluate the study based on the extracts from the study abstracts by answering the following questions:
a. What is the research question that the investigators are trying the answer?
b. What is their answer to the research question?
c. What were the methods they used to collect data?
d. Is the conclusion appropriate for the methods used to collect data?
e. To what population do the conclusions apply?
f. Have the results been replicated (reproduced) in other articles?
What Would Batman Do? Researchers have found that psychological distance from our current situation facilitates self-control and allows individuals to transcend urgencies of a situation by taking a more distanced perspective. Executive
Method: Three-year old
Results: Five-year-olds benefited from taking a self-distanced perspective on an executive function task through third person self-talk as well as taking the perspective of an exemplar other, such as Batman. Three-year-olds did not show increased EF performance as a function of greater distance from self.
Conclusion: The current study revealed the power of self-distancing to facilitate reflective, goal-directed action in the context of a cool EF task for young children. Children’s ability to improve EF by mentally transcending their context underscores the critical role that representational capacities play in the development of self-control.

- Find the critical value for a left-tailed test using the F distribution with a 0.025, degrees of freedom in the numerator=12, and degrees of freedom in the denominator = 50. A portion of the table of critical values of the F-distribution is provided. Click the icon to view the partial table of critical values of the F-distribution. What is the critical value? (Round to two decimal places as needed.)arrow_forwardA retail store manager claims that the average daily sales of the store are $1,500. You aim to test whether the actual average daily sales differ significantly from this claimed value. You can provide your answer by inserting a text box and the answer must include: Null hypothesis, Alternative hypothesis, Show answer (output table/summary table), and Conclusion based on the P value.
