为了确定头部下沉是否可以作为一种有效的勘探措施，开发了一种改进的孔板，在地板上有四个孔，可以放置新的物体。提出了将头部倾斜作为勘探措施的两个标准：第一，它应反映环境的新方面;第二，暴露于孔板应导致信息存储。头部下沉反映了新奇感，这一点在有物体的情况下，初次曝光时头部下沉的持续时间较长，在第二次曝光时，第一次引入物体时也是如此。信息存储表明再暴露于孔板的习惯。大鼠在“四”孔板和“十六”孔板中的头部浸入之间存在显著的正相关，但小鼠的头部浸入之间没有显著的正相关。这为“十六洞板”中的鼠头也反映了探索提供了一些间接证据。（+）安非他明和酒精进行了测试，在修改后的孔板，和（+）安非他明减少和酒精增加的频率和持续时间的头部下降。
To determine whether head-dipping could be validated as a measure of exploration a modified hole-board was developed with four holes in the floor, under which novel objects could be placed. Two criteria for considering head-dipping as a measure of exploration were proposed: firstly, that it should reflect novel aspects of the environment; secondly, that exposure to the hole-board should result in information storage. That head-dipping reflected novelty was indicated by the longer duration of head-dips on initial exposure if objects were present, and also on a second exposure when objects were introduced for the first time. Information storage was indicated by habituation on re-exposure to the hole-board. A significant positive correlation between head-dipping in the “four” and “sixteen” hole-boards was obtained for rats, but not for mice. This provided some indirect evidence that rat head-dipping in the “sixteen hole-board” also reflects exploration. (+)Amphetamine and alcohol were tested in the modified hole-board, and (+)amphetamine decreased and alcohol increased the frequency and duration of head-dips.
