To deny, to justify, or to apologize: Do social accounts influence stress levels in the aftermath of psychological contract breach?

Background: Workplace stress carries considerable costs for the employees' wellbeing and for the organization's performance. Recent studies demonstrate that perceptions of psychological contract breach are a source of stress for employees. That is, when employees notice that their employer does not fulfil certain obligations, they will perceive that certain resources are threatened or lost, which in turn translates into increased stress.

The neural representation of mental beliefs held by two agents.

Neuroimaging research has demonstrated that mentalizing about false beliefs held by other people recruits the temporo-parietal junction (TPJ). However, earlier work was limited to a single agent that held a false belief. We investigated the effect of two agents that held similar or mixed false and/or true beliefs.

Ultra-short term heart rate variability as a tool to assess changes in valence.

Heart rate variability (HRV) is an index that has been extensively used in fields such as clinical cardiology, psychiatry, and psychology to assess affective experiences. Although traditionally The European Society of Cardiology and The North American Society of Pacing and Electrophysiology recommended to use either a recording length of 24-h (long-term) or five minutes (short-term), recent advances in the field have suggested the use of ultra-short term (<5 min) HRV measurements. In this study, we investigated whether ultra-short term HRV measurements can be used to investigate the temporal dynamics of experimentally induced emotions using pictures from the International Affective Picture System.
