Self-compassion and its cultivation in psychological interventions are associated with improved mental health and well-being. However, the underlying processes for this are not well understood. We randomly assigned 135 participants to study the effect of two short-term self-compassion exercises on self-reported-state mood and psychophysiological responses compared to three control conditions of negative (rumination), neutral, and positive (excitement) valence. Increased self-reported-state self-compassion, affiliative affect, and decreased self-criticism were found after both self-compassion exercises and the positive-excitement condition. However, a psychophysiological response pattern of reduced arousal (reduced heart rate and skin conductance) and increased parasympathetic activation (increased heart rate variability) were unique to the self-compassion conditions. This pattern is associated with effective emotion regulation in times of adversity. As predicted, rumination triggered the opposite pattern across self-report and physiological responses. Furthermore, we found partial evidence that physiological arousal reduction and parasympathetic activation precede the experience of feeling safe and connected.

Modern society is reviving the practice of aromatherapy, and lavender is reported to be the most worldwide purchased plant for essential oils (EO) extraction. Since odors can modulate cognitive functions acting through specific neuroanatomical pathways, lavender EO inhalation can enhance cognition. Taking into account EO quality and diffusion devices, we conducted a systematic review on the effects of lavender EO inhalation on arousal, attention and memory in healthy subjects. Starting from this new multidisciplinary perspective, cognitive effects were revised to link outcomes to effective and reproducible aromatherapy protocols. A systematic search on MEDLINE database using Cognitive Atlas and plant authenticity-related keywords was performed. Among the 806 articles yielded, 11 articles met eligibility criteria. Subjects administered with lavender EO displayed arousal decrease and sustained attention increase. Puzzling results were obtained regarding memory. Lack of EO quality assessment and high heterogeneity in inhalation protocols did not allow assessing whether different EO composition differently modulates cognition and whether placebo or expectancy effect can be discerned from EO effect itself. However, GABAergic pathway modulation exerted by linalool, a major lavender EO constituent, explains arousal reduction and sustained attention enhancement. In conclusion, aromatherapy can be an innovative, practical and non-invasive tool to prevent cognitive lapses.

This study aimed at investigating the altruism praxis in English teaching and learning classroom activities in Senior High School. This study employed a case study and conducted in MAN Karawang. The data in this study were the occurence of altruism aspects in English teaching and learning classroom activities. This study employed two instruments in collecting data, namely observation and interview. This study revealed that three aspects of altruism, empathy; prosocial behavior and aversive-arousal reduction appeared in English teaching and learning classroom activities and the most dominant is prosocial behavior. In other words, it can be concluded that MAN Karawang has contributed in altruism praxis in English teaching and learning classroom activities. The contribution is shown by habituating and maintaining the behaviors that represent aspects of altruism, such as Student follows teacher`s instruction; Student lends others stuffs they do not have and student uses positive language during discussion.
