&本文分析了性别和性别动态之间的相互作用，即，人们打字的方式和他们打字的内容。特别是，实验表明，不同性别的人在通过Whatsapp或Skype等流行产品中的实时聊天界面进行互动时，往往会输入不同的内容。结果分析表明，这些差异主要涉及情感状态的表达，传达社会存在的方式，以及计划问题的频率（决定下一步输入什么的困难）。此外，实验表明，差异是足够一致的，允许自动性别识别的准确率高于95%。换句话说，打字行为似乎是一个可靠的性别标记，至少在通过基于文本的实时聊天互动的情况下。社会互动的主要特征之一是非语言行为线索（面部表情，手势，发声等）的普遍使用。社会心理学已经广泛地研究了面对面互动的情况下的现象，在这种情况下，人们可以随意使用他们的自然表达方式（面部、身体、声音等）。然而，目前还不清楚当通过技术进行通信时会发生什么（例如，实时聊天和消息系统），不允许使用非语言提示。换句话说，目前还不清楚这些技术介导的通信是否涉及非语言成分，如果是，是否有非语言线索传达数字对象标识符10.1109/MIS.2019.2948514
& THIS ARTICLE ANALYZES the interplay between gender and keystroke dynamics, i.e., the way people type as opposed to what they type. In particular, the experiments show that people of different gender tend to type differently when they interact through live-chat interfaces like those available in popular products such as Whatsapp or Skype. The analysis of the results shows that the differences concern mostly the expression of affective states, the way of conveying social presence, and the frequency of planning problems (the difficulties in deciding what to type next). In addition, the experiments show that the differences are sufficiently consistent to allow automatic gender recognition with accuracy higher than 95%. In other words, typing behavior appears to be a reliable gender marker, at least in the case of the interaction through text-based live-chats. One of the main features of social interaction is the pervasive use of nonverbal behavioral cues (facial expressions, gestures, vocalizations, etc.) conveying socially and psychologically relevant information such as attitudes, emotions, personality, gender, etc. Social psychology has extensively investigated the phenomenon in the case of face-to-face interactions in which people have at disposition their natural means of expression (face, body, voice, etc.). However, it is still relatively unclear what happens when communication takes place through technologies (e.g., live-chats and messaging systems) that do not allow the use of nonverbal cues. In other words, it is still relatively unclear whether communication mediated by such technologies involves a nonverbal component and, if yes, whether there are nonverbal cues that convey Digital Object Identifier 10.1109/MIS.2019.2948514
