科学领域:

神经科学是一个神经科学.
数字健康数字健康
精神病学是一个精神病学.

背景情况:

幻觉在帕金森病 (PD) 中很常见,与痴呆和死亡率有关.
目前对幻觉的主观评估容易产生偏见.
缺少PD中幻觉的客观生物标志物.

研究的目的:

开发和验证一个数字标记,用于量化帕金森病中的存在幻觉.
评估PD患者远程,家庭数字评估的可行性.

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...
