Guéguen and de Gail's Field Experiment on Helping Behavior
In a field experiment investigating helping behavior, researchers Nicolas Guéguen and Marie-Agnès de Gail tested whether being smiled at increased the likelihood that supermarket shoppers would help a confederate pick up dropped computer diskettes. Because the study involved people's ordinary activities and posed no expected harm, the researchers dispensed with obtaining informed consent. Furthermore, since participants were encountered naturally rather than formally recruited, the researchers utilized strict, predetermined selection rules to prevent unintentional experimenter bias. Specifically, they targeted the first person appearing to be between the ages of 20 and 50 encountered on a stairway, and only if the person gazed back did they become a participant in the study.

What is the primary purpose of establishing explicit participant selection rules before data collection begins in a field experiment?
When conducting field experiments where participants are encountered naturally, researchers may adjust their selection criteria during data collection to ensure they capture the most interesting behaviors.
A researcher is studying helping behavior in a busy subway station. To prevent selection bias, arrange the following steps in the correct chronological order to show how participant selection rules are applied in this environment.
A researcher is conducting a field experiment on helping behavior in a public park. To ensure the results are valid and free from experimenter bias, they must implement strict participant selection rules. Match each selection rule to the specific analytical safeguard it provides.
Match each component of participant selection rules in field experiments with its specific requirement or goal.
When conducting a field experiment where participants are encountered naturally, why is it essential to finalize selection rules before data collection begins?
A peer reviewer concludes that a field experiment lacks objectivity because the researcher chose which individuals to observe based on their 'approachability' in the moment. To reach the standard of a high-quality empirical study, the researcher should have utilized _____ selection rules established before data collection to eliminate this source of bias.
A researcher conducting a field experiment on helping behavior in a public park writes a rule beforehand stating that they will study only every third person who walks past a specific park bench. If the researcher adheres strictly to this predetermined rule during data collection, they are correctly applying participant selection rules to prevent experimenter selection bias.
A research team plans to observe pedestrian reactions to a staged emergency in a subway station. If they do not establish explicit inclusion criteria before beginning, the study's internal validity is threatened by _____ bias, which can occur intentionally or unintentionally during data collection.
To ensure a field experiment minimizes selection bias and maintains methodological rigor, arrange the following steps of the participant selection workflow in the correct chronological order:
Describe the requirements for establishing participant selection rules in a field experiment where participants are encountered naturally, and explain the primary purpose of having these rules.
Diagnose the methodological flaw in this researcher's approach based on the principles of participant selection in field experiments. What is the specific consequence of this flaw?

Guéguen and de Gail's Field Experiment on Helping Behavior
Under which of the following conditions might an Institutional Review Board (IRB) allow a researcher to dispense with obtaining informed consent?
Researchers are strictly prohibited from conducting any psychological study without first obtaining informed consent from all participants.
Match each proposed research scenario with the most appropriate Institutional Review Board (IRB) guideline regarding informed consent.
A researcher plans to observe how strangers react to a staged minor mishap in a public park to study prosocial behavior. Arrange the following criteria in the logical order that an Institutional Review Board (IRB) would analyze them to determine if the researcher can dispense with informed consent, moving from the situational context to the final safety determination.
A social psychologist is designing an unrecruited field experiment to observe how environmental factors influence altruistic behavior in a public park. Construct the logical progression of the researcher's protocol-design process to synthesize a valid justification for a waiver of the standard participant agreement process.
Which of the following research methods is most likely to be permitted by an Institutional Review Board (IRB) to dispense with obtaining informed consent?
Match each core concept related to ethical research conduct with the specific role it plays in determining whether informed consent can be waived.
A researcher proposes an unrecruited field experiment to observe prosocial behavior by having a confederate drop groceries in a busy shopping mall. To evaluate whether this study qualifies for a waiver of informed consent, an Institutional Review Board (IRB) must determine that the procedure occurs during the participants' ordinary, everyday activities and is not expected to cause any _____.
A professor teaching two sections of the same introductory psychology course decides to compare two legitimate instructional approaches: one section completes weekly paper-based quizzes while the other uses an online quiz platform. She measures exam performance at the end of the semester without obtaining signed informed consent from her students. True or False: When analyzed against the two key conditions IRBs apply under APA Standard 8.05, this study most likely qualifies for dispensing with informed consent because it compares legitimate pedagogical methods within students' ordinary academic activities and poses no anticipated harm.
A researcher designs an unrecruited field experiment in which a confederate accidentally drops a folder of papers near the entrance of a busy campus cafeteria while an observer records whether nearby strangers stop to help retrieve them. The researcher argues that no informed consent is needed. When an IRB evaluates this waiver request, the critical judgment it must make—beyond confirming there is no anticipated harm—is whether a staged mishap of this kind falls within events that people typically encounter during their _____ activities.
Based on Institutional Review Board (IRB) and APA Ethics Code guidelines, recall and describe the specific conditions under which researchers are permitted to dispense with obtaining informed consent from participants in a psychological study.
Given this scenario, demonstrate your comprehension of ethical guidelines by explaining why an Institutional Review Board (IRB) would likely allow the researcher to dispense with informed consent.
Apply ethical guidelines to the following scenario: A college instructor wants to compare two legitimate teaching methods across two sections of his research methods course. Decide whether the instructor needs to obtain informed consent from the students, and justify your decision in one to three sentences.
