Increasingly, clinicians obtain data from tests across modalities. Little actual information, however, exists as to normal patterns. An example is auditory and visual recall of digit span. The effects of modality on recall of digit span, sequence, and order were examined with 80 subjects (M age 24.3 yr.). Subjects were given the Wechsler Adult Intelligence Scale-Revised, and a research version of MicroCog: Assessment of Cognitive Functioning. Both contain forward and backward digit spans. Recall for visual presentation was significantly stronger than for auditory presentation of backward digit span. Recall for visual backward digit span was also superior to auditory backward digit span when the sequence of presentation was controlled. The mean number of digits recalled was higher when visual digit span was preceded by auditory digit span.
临床医生越来越多地从多种检查方式中获取数据。然而，关于正常模式的实际信息却很少。一个例子是数字广度的听觉和视觉回忆。对80名受试者（平均年龄24.3岁）进行了检查，以研究检查方式对数字广度、序列和顺序回忆的影响。受试者接受了韦氏成人智力量表修订版以及MicroCog研究版：认知功能评估。两者都包含顺背和倒背数字广度。倒背数字广度的视觉呈现回忆明显强于听觉呈现。当呈现顺序得到控制时，视觉倒背数字广度的回忆也优于听觉倒背数字广度。当视觉数字广度之前有听觉数字广度时，回忆的平均数字数量更高。
