The relative efficacy of (1) repeated auditory and somesthetic stimulation for the habituation of cardiac acceleration responses and (2) intramodal and cross-modal stimulation for the dishabituation of cardiac responses was studied in 45 full-term 2-day-old infants. Although the stimuli were equally effective initially, repeated presentation of the somesthetic stimulus had a greater decremental effect than repeated presentation of the auditory stimulus. The stimuli were equally effective in producing dishabituation when in a different modality from that of the habituating stimulus (cross-modal) but not when in the same modality (intramodal). Changes in the locus of stimulation without a change in modality were ineffective for producing dishabituation. The findings indicate the human newborn discriminates auditory and somesthetic inputs effectively and equally but does not discriminate contralateral from ipsilateral stimulation in either modality.
对45名足月出生2天的婴儿进行了研究，探讨了(1)重复听觉和躯体感觉刺激对心脏加速反应习惯化的相对功效，以及(2)模式内和跨模式刺激对心脏反应去习惯化的功效。虽然最初刺激同样有效，但重复呈现躯体感觉刺激比重复呈现听觉刺激具有更大的递减效应。当刺激与习惯化刺激处于不同模式（跨模式）时，它们在产生去习惯化方面同样有效，但当处于相同模式（模式内）时则不然。刺激部位改变而模式不变对产生去习惯化无效。研究结果表明，人类新生儿能有效且同等地辨别听觉和躯体感觉输入，但在任何一种模式下都无法区分对侧刺激和同侧刺激。
