The present work provides robust insights into how cognitive ability is correlated to personality traits. We investigated how cognitive ability (operationalized as facets of working memory capacity) is linked to the Big Five personality traits on broader domain- and facet-levels, as well as with individual personality inventory items. The effective sample comprised 1211 people (55% female; age M = 31.39, SD = 11.76) who participated in the study via a smartphone application where they filled out a personality test, and solved six working memory capacity tasks (based on two binding paradigms with different stimulus types). In addition to bivariate analyses, we used network analysis to model cognitive ability in relation to personality on different aggregation levels. We found that Openness, its facet Intellectual and some items of the Openness domain were consistently associated with cognitive ability tasks. While some of the earlier findings were replicated, we also provide novel findings with robust methodology across different levels of personality and by differentiating the facets of cognition. All in all, personality is not substantially correlated with cognitive ability, and the links with Openness are weak.

目前的工作为认知能力如何与人格特质相关提供了强有力的见解。我们调查了认知能力（作为工作记忆容量的方面进行操作）如何与更广泛的领域和方面级别的大五人格特质以及个人人格清单项目相关联。有效样本包括 1211 人（55% 女性；年龄 M = 31.39，SD = 11.76），他们通过智能手机应用程序参与了这项研究，他们在其中填写了性格测试，并解决了六项工作记忆容量任务（基于两个绑定范式）具有不同的刺激类型）。除了双变量分析外，我们还使用网络分析对不同聚合水平上与人格相关的认知能力进行建模。我们发现开放性，它的智力方面和开放性领域的一些项目始终与认知能力任务相关联。虽然复制了一些早期的发现，但我们还通过跨不同人格水平和区分认知方面的稳健方法提供了新颖的发现。总而言之，人格与认知能力没有实质性的相关性，与开放性的联系较弱。
