Based on the concept of minimizing risks through research design modification, what specific action should the researcher take regarding the visual stimuli, and what is the underlying goal of this modification?
Case context: A researcher is developing a study to measure physiological reactions to fear. The initial research design involves suddenly exposing participants to highly offensive and upsetting images of violent crime scenes. The researcher realizes this poses a significant risk of causing psychological harm.
Question: Based on the concept of minimizing risks through research design modification, what specific action should the researcher take regarding the visual stimuli, and what is the underlying goal of this modification?
Sample answer: The researcher should replace the highly offensive and upsetting violent images with milder alternatives. The goal of this modification is to ensure the study remains effective in measuring reactions to fear while subjecting participants to significantly less stress.
Key points:
- Replace highly offensive stimulus materials with milder alternatives.
- Subject participants to less stress.
- Ensure the study remains effective.
Rubric: Award full points if the student correctly identifies replacing the extreme stimuli with milder ones and explains that it balances the study's effectiveness with reduced participant stress.

How can researchers effectively minimize psychological risks to participants after identifying potential hazards in their study design?
Match each risk-reduction strategy with the specific participant concern it is designed to address in a psychological research study.
A researcher studying the effects of frustration on problem-solving realizes that their original plan to use an impossible 2-hour task is causing participants excessive distress. Arrange the steps the researcher should take to apply the strategy of 'minimizing risks through research design modification' to this study.
A researcher studying cognitive performance identifies that a planned 2-hour uninterrupted testing session is likely to cause excessive participant frustration. To address this, they break the task into four 30-minute sessions with rest periods. True or False: This change effectively applies a risk-minimization strategy by analyzing the procedure to isolate and reduce a specific hazard (duration) while maintaining the study's focus on the primary variable (cognitive performance).
According to the strategy of minimizing risks through research design modification, how can researchers reduce potential hazards to participants while keeping the study effective?
If a researcher identifies that their planned experimental procedure might cause severe participant frustration, the strategy of research design modification requires them to completely abandon their research question.
A researcher evaluates a study and determines that a planned task causes excessive frustration in participants. By choosing to simplify the task to reduce stress while ensuring the study remains effective, the researcher is utilizing research design _____ as an ethical strategy.
Match each researcher's modification scenario to the specific risk-minimization strategy they are applying.
A researcher decides to simplify a highly complex experimental procedure to prevent participant frustration. By implementing this risk minimization strategy, the researcher ensures the study remains _____ while subjecting participants to less stress.
Order the steps a researcher should follow to evaluate and modify their research design to address participant risk while maintaining the study's validity.
According to the principle of research design modification, what are two specific ways a researcher can alter their study to eliminate or reduce potential hazards to participants?
Based on the concept of minimizing risks through research design modification, what specific action should the researcher take regarding the visual stimuli, and what is the underlying goal of this modification?
If a cognitive psychology experiment requires participants to solve math problems, but pilot testing shows the problems are so overly complex that they cause extreme distress, how can the researcher apply the strategy of research design modification?
