Task-dependent variation in native vs English prompt effectiveness

URL: https://arxiv.org/abs/2505.11665

Extract¶

"Performance comparisons between Native-Basic and En-Basic vary depending on the specific NLP task, with Native-Basic outperforming En-Basic in tasks such as Emotion/Sentiment Understanding and Coreference Resolution." This indicates the relationship between prompt language and performance is not uniform — it depends on the task type.

Relevance to Hypotheses¶

Hypothesis	Relationship	Strength
H1	Supports	Confirms that performance does vary across languages
H2	Contradicts	Shows measurable differences exist
H3	Supports	Directly demonstrates task-dependent conditionality — native prompts win on some tasks, English on others

Context¶

This finding is critical because it shows the answer is not simply "English is always better" or "native is always better" — the optimal prompt language depends on the task.
