In this study the influence of the information value of visual stimuli on habituation of the visual orienting reaction (VOR) and the skin conductance reaction (SCR) was investigated. 28 subjects received two blocks of 14 trials. Half the subjects received the higher information condition first and then the lower information, the other half received the conditions in the reversed order. Subjects fixated the stimuli with the higher information value longer than the stimuli with the lower information value during the 14 trials and habituated slower. This effect of information was absent in the second block and VOR habituation was also faster in this block. There was no difference in SCR amplitudes nor in SCR habituation scores between the two information conditions, neither in block 1 nor in block 2. The results of this study are discussed in relation with a two-stage model of the OR.
在本研究中，研究了视觉刺激的信息价值对视觉定向反应（VOR）和皮肤电反应（SCR）习惯化的影响。28名受试者接受了两个包含14次试验的组块。一半受试者先接受高信息条件，然后是低信息条件，另一半受试者则以相反顺序接受条件。在14次试验中，受试者注视信息价值高的刺激的时间比信息价值低的刺激更长，且习惯化更慢。在第二个组块中，这种信息效应不存在，并且该组块中的VOR习惯化也更快。在两个信息条件之间，无论是在组块1还是组块2中，SCR幅度和SCR习惯化分数均无差异。本研究结果结合OR的两阶段模型进行了讨论。
