Age-variant configurations of emotional episodic memory evaluated by natural language processing, machine learning, and network graph analysis
Considering that emotional events diversify as one ages, this study formulates the Salient Episodic Memory Aggregation Hypothesis, which claims that aging induces homogenization of episodic memory and consequently increases the salience of emotional episodes. To test this hypothesis, the study focused on sadness episodic memory and conducted a web-based survey and a combined analysis consisting of natural language processing, machine learning, an…
Beliefs About the Positive Functions of Sadness
Sadness involves adaptive functions such as eliciting help from others or analysing the causes of failure. It also has positive features such as empathy or the co‐occurrence of positive emotions. Previous studies have revealed that Asians are more likely than Westerners to perceive the utility of negative emotions. However, common people's beliefs about the positive functions of specific emotions, including sadness, remain unclear. This study aim…
Do momentary phenomena evoke mixed emotions
Previous studies have revealed that meaningful endings cause people to experience mixed emotions. Endings are ubiquitous in various facets of our lives and can be categorised into personally meaningful (e.g., a graduation ceremony) and less personally meaningful experiences (e.g., falling flowers). However, it is unclear whether less personally meaningful endings evoke mixed emotions similar to meaningful endings. We hypothesised that awareness o…
Effects of Participating in a Short-Term Workcation on Psychological and Physiological Responses
This study examines the effects of a short-term workcation on psychological and physiological responses. A group of corporate executives ( n = 20) volunteered to participate in a three-day workcation program (WG) along with a control group ( n = 20) working on daily jobs at usual office (CG). Psychological responses were obtained three times, namely in the week before the workcation, at the end of the workcation day, and one week after the workca…
Differential perception of shame in the Japanese
Although laughter is typically considered to be a positive expression, being laughed at by someone else evokes several types of negative emotions. However, the changes in the negative emotions recognized after being laughed at compared to before have yet to be clarified. The present study investigated the emotional responses and the relationship between the intensity of these emotions and gelotophobia when laughed at due to an unexpected failure …
Hierarchical memory representation of verbal and nonverbal features for emotion
The Role of Bodily Expression in Memory Representations of Sadness
Deconstructing disgust as the emotion of violations of body and soul
Through the evolutionary process of preadaptation, disgust was coopted to serve as the guardian not just of one's body but also of one's soul-or so it has been theorized. On this theory, elicitors include health-related threats and nonhealth-related degrading acts, which together form a pancultural domain of morality. A prediction from this theory was examined here in four samples: 96 English-speaking Americans, 96 Malayalam-speaking Indians, 136…
Color features continuously represent negative and positive aspects of sadness
Emotion is assumed to be stored in long-term memory as a concept by a feature (e.g., "tears" for "sadness") that is a memory unit of a concept. Memory activation of emotion concepts via features is supposed to enable recognition of emotional states. Emotion concepts are associated with various perceptual features oriented toward the interior and exterior of the body. Although previous studies have revealed that internal perceptual features need t…
Neurophysiological foundations of loss and failure sadness differently modulate emotional conceptual processing
Sadness is divided into two subtypes, namely loss and failure sadness, which are encoded by different concepts of one's mind. However, it is unclear how such a conceptual difference is supported by neurophysiological foundations. In the present study, we conducted an electroencephalogram experiment for processing congruency between loss- and failure-sadness contexts and emotional words. Electroencephalogram recordings were performed for 23 partic…
