We replicated previous research in which adults with dementia tended to show a preference for leisure items over edible items when presented in the same array. Additionally, we conducted engagement analyses with the highest, middle, and lowest preference leisure items to determine whether relative preference corresponded to engagement in the natural environment. The most highly preferred stimulus for 6 out of 7 participants was a leisure item, and for each of those six the top 3 preferred stimuli were leisure stimuli. For 4 participants, the most preferred stimulus also produced the longest duration of engagement. We discuss the issues we encountered when conducting preference assessments with adults with intact vocal verbal repertoires, and suggest potential explanations for the displacement of edibles by leisure stimuli in older adults with dementia.
我们复制了之前的研究,当在同一组中呈现时,痴呆症成年人往往更倾向于选择休闲物品而不是食用物品。此外,我们对最高、中等和最低偏好的休闲物品进行了参与度分析,以确定相对偏好是否与自然环境中的参与度相对应。在 7 名参与者中的 6 名中,最受欢迎的刺激是休闲物品,对于这 6 名参与者中的每一名,前 3 名最受欢迎的刺激都是休闲刺激。对于 4 名参与者来说,最受欢迎的刺激也产生了最长的参与时间。我们讨论了在具有完整口头言语词汇的成年人中进行偏好评估时遇到的问题,并为痴呆症老年人中食用物品被休闲物品取代提出了潜在的解释。
