level of arousal; level of awakeness
Technical term used in psychology, neuroscience, and sleep medicine to describe the degree of alertness or consciousness.
When the level of arousal is low, reactions become slower.
In this experiment, the subjects' level of arousal was measured.
覚醒 means 'awakening' or 'arousal' in a general sense, while 覚醒水準 specifically refers to the measurable level or degree of that state.
意識レベル is a more clinical term often used in medical contexts to describe levels of consciousness, whereas 覚醒水準 is broader and used in psychological research.
Compound of 覚醒 (かくせい, 'awakening, arousal') and 水準 (すいじゅん, 'level, standard'). The term is a direct translation of the English 'arousal level' and is used primarily in academic contexts.
