Expressing emotions in blogs: The role of textual paralinguistic cues in online venting and social sharing posts
ابراز احساسات در وبلاگ ها: نقش نشانه های زبانشناختی متنی در خروجی آنلاین و پست های اشتراک اجتماعی-2017 Textual paralanguage cues (TPC) have been signaled as effective emotion transmitters online. Though
several studies have investigated their properties and occurrence, there remains a gap concerning their
communicative impact within specific psychological processes, such as the social sharing of emotion
(SSE, Rime, 2009). This study content-analyzed Live Journal blogposts for the occurrence of TPC in three
phases of online SSE: initiation, feedback and repost. We compared these to TPC on a second type of
emotional expression, emotional venting. Based on Social Information processing theory (SIP, Walther,
1992), and on the Emotional Mimicry in Context (EMC, Hess & Fischer, 2013) framework, we study
predictive relationships in TPC usage in our phased model of online SSE. Results showed that TPC pre
vailed in SSE blogposts and strongly dominated in emotional venting posts. TPC was more common in
affective feedback than cognitive. Moreover, the presence of tactile affective cues (i.e., hugs, kisses) in the
initiation post predicted their presence in affective feedback. Results lend support to the idea that TPC are
used in socio-contextual ways in online SSE and particularly extrapolate certain FtF nonverbal behaviors,
such as the provision of socio-affective touch.

Perceiving emotions in robot body language: Acute stress heightens sensitivity to negativity while attenuating sensitivity to arousal
درک احساسات در زبان بدن ربات: استرس حاد حساسیت به منفی را افزایش می دهد در حالی که احساس حساسیت به آرامش را کاهش می دهد-2017 Reliance on socioemotional assistive robots is projected to increase, yet little is known about how our ability to perceive their emotional expression is impacted by psychological factors. In high-risk and high- tension domains such as emergency services and healthcare, how might the cognitive and physiological stress we are experiencing influence how we read a humanoid robots nonverbally conveyed emotions? Using a novel paradigm, we asked participants under experimentally-induced acute stress vs. low stress to evaluate a set of normed emotional body language poses conveyed by a physically-present vs. virtually-instantiated humanoid robot. Participants rated each pose for emotional valence (negativity/ positivity) and arousal (calm/excited). Acute stress increased the perception of negative valence in negative high arousal poses, consistent with stress-induced hypervigilance. Surprisingly, stress dimin- ished the perception of arousal in high arousal poses, whereas repeated presentation of the low arousal poses increased perception of arousal. Participants rated emotion similarly for the physically-present vs. virtually-present robot, although positively-valenced poses conveyed by the physical robot were perceived as more positive and more animate. We propose that perceptions of emotional arousal may be especially vulnerable to context effects and misattribution. These findings have implications for how assistive robots can best be designed for high-risk and high-tension contexts.© 2017 Elsevier Ltd. All rights reserved.
