threshold; limen
Technical term in psychology for the point at which a stimulus is perceived or a response is triggered. Often used in compounds like 刺激閾 (stimulus threshold) and 弁別閾 (difference threshold).
The stimulus threshold refers to the minimum stimulus intensity that produces a sensation.
弁別閾の実験では、二つの刺激の差がどの程度で気づかれるかを調べる。
In difference threshold experiments, we examine how much difference between two stimuli is needed to be noticed.
