Using the regulation of accuracy to study performance when the correct answer is not known

Area of Science:

• Cognitive Psychology
• Memory Research

Background:

• Investigating memory performance in multiple-choice questions is crucial for understanding recall accuracy.
• The impact of the absence of correct answers on participant response strategies requires further examination.

Purpose of the Study:

• To determine how participants respond to multiple-choice questions when the correct answer may be absent.
• To explore the effects of allowing participants to choose the number of alternatives (plurality option) and to report or withhold their answer (report option).
• To assess memory benefits when both plurality and report options are available.

Main Methods:

• Two experiments were conducted where participants answered multiple-choice questions after watching a crime scenario.
• Participants used a plurality option (selecting one vs. three alternatives) and a report option (reporting vs. withholding the answer).
• Confidence ratings were collected after initial and final selections.

Main Results:

• Participants exhibited higher confidence, selected more single answers, and preferred to report more often when the correct alternative was present.
• A posteriori classification of questions (with vs. without correct alternative) based on participant selections was better than chance but limited by misclassifications.
• The memory benefits associated with both the plurality and report options were found to overlap.

Conclusions:

• The presence of the correct alternative influences participant confidence and reporting behavior in multiple-choice tests.
• While classification of question types from responses shows promise, its forensic application is currently limited.
• The study demonstrates overlapping memory benefits from employing both plurality and report options in memory tasks.
