The present study was aimed at assessing the behavioural and physiological responsiveness of three children with profound intellectual and multiple disabilities to a set of sensory stimuli.
Eighteen items, 'believed' by clinicians to be appropriate for routine interventions, were presented to the participants and responsiveness was assessed in terms of: (i) consistent behavioural and electrodermal reactions and (ii) biphasic changes in heart rate.
Results were twofold. First, all participants showed frequent consistent physiological reactions but rare consistent behavioural ones. Second, all participants showed biphasic changes in heart rate, pointing to the possibility of different appraisals (novelty and pleasantness) of most of the presented items.
Data here presented may have implications for the development and the emotional well-being of individuals with profound intellectual and multiple disabilities in that it suggests that reactions to, and potential appraisals of, sensory stimuli may occur despite the lack of consistent observable behaviours.
本研究旨在评估三名重度智力和多重残疾儿童对一组感觉刺激的行为和生理反应。
向参与者呈现临床医生认为适合常规干预的18个项目，并从以下方面评估反应：（i）一致的行为和皮肤电反应，以及（ii）心率的双相变化。
结果有两方面。第一，所有参与者都频繁出现一致的生理反应，但很少出现一致的行为反应。第二，所有参与者都表现出心率的双相变化，这表明大多数呈现的项目可能存在不同的评估（新颖性和愉悦性）。
此处呈现的数据可能对重度智力和多重残疾个体的发展和情绪健康有影响，因为这表明尽管缺乏一致的可观察行为，但对感觉刺激的反应和潜在评估可能会发生。
