Summary
People can learn to distinguish human from AI-generated text with immediate feedback. This training corrects misconceptions about AI writing style and improves self-assessment accuracy, crucial for education.
Area of Science:
- Cognitive Psychology
- Natural Language Processing
- Human-Computer Interaction
Background:
- The proliferation of AI-generated text necessitates methods for accurate detection.
- Misconceptions about AI writing characteristics, such as style and readability, are common.
- Overconfidence in identifying AI text can lead to errors, particularly in educational settings.
Purpose of the Study:
- To determine if individuals can learn to accurately discriminate between human and AI-generated texts with immediate feedback.
- To assess if feedback helps recalibrate self-perceived competence in AI text identification.
- To explore the criteria (textual style, readability) individuals use for discrimination.
Main Methods:
- GPT-4o generated AI texts; Koditex corpus provided human texts.
- 254 Czech native speakers participated in a text-pair identification task.
- Two conditions: immediate feedback vs. delayed feedback.
Main Results:
- Immediate feedback significantly improved accuracy and confidence calibration.
- Participants initially held incorrect assumptions about AI text features.
- Without feedback, errors peaked during high confidence; feedback mitigated this.
- Learners corrected misconceptions regarding AI stylistic rigidity and readability.
Conclusions:
- Targeted training with explicit feedback effectively teaches AI text differentiation.
- Feedback corrects misconceptions about AI stylistic features and readability.
- Accurate self-assessment is facilitated, reducing harmful overconfidence in educational contexts.
