While emotional responses experienced appear to remain intact in Parkinson's disease (PD), no study has tested whether this extends to the prediction of emotional responses. The present study aimed to provide the first assessment of affective forecasting capacity in this cohort.
A positively and negatively valenced affective forecasting task and broader clinical battery were completed by a PD group ( = 28 and 37, respectively) and a demographically matched neurotypical control group ( = 38 and 39, respectively).
No group differences emerged on the two tasks, with the two groups underestimating their level of happiness and overestimating their level of negative affect to a similar degree. Affective forecasting error scores were unrelated to clinical characteristics.
Given that affective forecasting relies on self-projection into the future, a skill shown to often be disrupted in this cohort, impairments were expected. However, this study provides initial evidence that this may not be the case. These findings are potentially important given that how we think about and envisage the future affectively is a major determinant of goal-directed behavior. Further work is now needed to establish whether these findings are robust and generalize to other types of affective stimuli.
虽然帕金森病（PD）患者所经历的情绪反应似乎保持完好，但尚无研究测试这是否延伸至情绪反应的预测。本研究旨在首次评估该队列中的情感预测能力。
一个PD组（分别为28人和37人）和一个人口统计学匹配的神经典型对照组（分别为38人和39人）完成了一项具有正负效价的情感预测任务以及更广泛的临床测评。
在这两项任务中未出现组间差异，两组对自身幸福水平的低估程度和对自身消极情绪水平的高估程度相似。情感预测误差分数与临床特征无关。
鉴于情感预测依赖于对未来的自我投射，而这一技能在该队列中常常受到干扰，所以预计会出现障碍。然而，本研究提供了初步证据表明情况可能并非如此。鉴于我们如何从情感上思考和设想未来是目标导向行为的一个主要决定因素，这些发现可能具有重要意义。现在需要进一步开展工作，以确定这些发现是否可靠，并推广到其他类型的情感刺激。
