受測者自身的感覺與研究者的觀察之間，兩者有何矛盾之處?

 

答案是：

(3)在睡前6小時喝下咖啡的受測者，他們對自己睡眠的時間還有睡眠的質的感覺


【原文段落】

Finally, disruptions to sleep as a result of caffeine were perceived by volunteers for caffeine consumed at bedtime and 3 hours before bed, but were not reported for caffeine taken 6 hours before bed.


就寢時間喝咖啡以及睡前3小時喝咖啡的受測者都有感覺到睡眠被咖啡因擾亂，但睡前6小時喝咖啡的受測者卻沒有向研究者回報類似的狀況。(但實際上，6小時的受測者還是有受到咖啡因影響的)
