印象形成的主导模型集中在两个基本维度上:温暖/交流/可信度的水平维度和能力/代理/优势的垂直维度。然而,这些模型通常使用理论驱动的方法和有限复杂性的刺激进行研究。我们使用数据驱动的方法和自然刺激来探索来自2188名参与者的1000张Facebook个人资料图片的>300,000无约束语言描述的潜在维度。通过传统(探索性因素分析)和现代(自然语言词典,语义句子嵌入)方法,我们观察到关于水平和垂直维度及其各自的社交能力/道德和能力/自信方面的印象形成,再加上性别的关键人口统计学变量,年龄,和种族。然而,我们还观察到沿着许多进一步的维度形成的印象,包括冒险,保守主义,健身,不合格,和时尚。这些结果有助于强调印象形成的高维模型的重要性,并有助于阐明个体无约束描述的内容维度。
Dominant models of impression formation focus on two fundamental dimensions: a horizontal dimension of warmth/communion/trustworthiness and a vertical dimension of competence/agency/dominance. However, these models have typically been studied using theory-driven methods and stimuli of restricted complexity. We used a data-driven approach and naturalistic stimuli to explore the latent dimensions underlying >300,000 unconstrained linguistic descriptions of 1,000 Facebook profile pictures from 2,188 participants. Via traditional (Exploratory Factor Analysis) and modern (natural language dictionaries, semantic sentence embeddings) approaches, we observed impressions to form with regard to the horizontal and vertical dimensions and their respective facets of sociability/morality and ability/assertiveness, plus the key demographic variables of gender, age, and race. However, we also observed impressions to form along numerous further dimensions, including adventurousness, conservatism, fitness, non-conformity, and stylishness. These results serve to emphasize the importance of high-dimensional models of impression formation and help to clarify the content dimensions underlying unconstrained descriptions of individuals.
