Nine squirrel monkeys were required to select from various sets of stimuli-differing in size or brightness-either in terms of relational criteria or on an absolute stimulus basis. The level of information processing required by each task was assessed by means of stimulus transformation techniques, variations in set size, and by the elimination of the visible context. It was found that some relational judgements make fewer processing demands on the subject than do absolute stimulus judgements; the 'middle' relation, however, appears much more difficult to use than selection of a stimulus on an absolute basis and may be beyond the competence of the squirrel monkey. The results are seen as support for the thesis as advanced by McGonigle and Jones that the criteria of judgement, when varied, change the depth of stimulus processing by monkey as well as man.
九只松鼠猴需要根据关系标准或绝对刺激基础，从大小或亮度不同的各种刺激组中进行选择。通过刺激转换技术、组大小的变化以及消除可见背景，评估了每个任务所需的信息处理水平。研究发现，一些关系判断对受试者的处理要求比绝对刺激判断少；然而，“中间”关系似乎比基于绝对基础选择刺激更难使用，可能超出了松鼠猴的能力范围。这些结果被视为对麦戈尼格尔和琼斯提出的论点的支持，即判断标准变化时，会改变猴子和人类的刺激处理深度。
