Empirical studies that have used the STS have reported an association between scores and well-being in a variety of populations, including healthy young adults, and an increase in scores due to health-related vulnerability and age. [...]the TCI-ST includes many items with supernatural, spiritual, and religious nuances, probably due to the multidimensional nature of TCI and the need for differentiation from other adaptive dimensions. Because of its uniqueness, the TCI-ST has gained significant attention and has been used in many studies. A three-way analysis of variance of disaster experience (two levels) × age (20s to >70s; six levels) × sex (two levels) showed medium (η2 > 0.06) and small (η2 > 0.01) main effect sizes for disaster experience [F(1, 2526) = 190.629, p < 0.001, η2 = 0.068] and age [F(5, 2526) = 10.562, p < 0.001, η2 = 0.019]; I inferenced significance using the effect size η2 (Cohen, 1992) rather than p-value, considering the large sample size. (A) Average and standard deviation (error bar) of the score (%max) of self-transcendence (ST) factor of the power to live (P2L) questionnaire separately for six age levels (from 20s to over 70) and two groups: disaster survivors (dark gray) and normative population (light gray).

It has been widely recognized that moral decisions are processed by both emotional and reasoning systems. But the mechanisms for difficulty perceptions and how are they related to the two systems is still unclear. Here, we tested 3 potential factors, value difference, mean value of the options, and values of the victims. A new paradigm was developed to quantify the option values and to dissociate emotional and utilitarian values. Hypothesis were tested with the correlations of perceived difficulties and those 3 factors with linear mixed-effect model. First, data showed that both emotional and utilitarian value differences are negatively correlated with perceived difficulties, demonstrating its fundamental role in difficulty perception. Then, it was found that higher mean emotional value of the options adds difficulty to reasoning-motivated decisions, while higher mean utilitarian value of options showed no effect, indicating that the interaction can be asymmetric between the two systems. Lastly, both emotional and utilitarian values of the victim (i.e. unchosen) are positively correlated with perceived difficulties, showing that victim is also a critical factor. These results update the framework of difficulty perception in moral decisions, adding more to the basic value difference.

Body-image disturbance comprises two components. The first is perceptual in nature, and is measured by a discrepancy between one’s actual body and perceived self-image (“perceived–actual discrepancy”). The other component is affective, and is measured by a discrepancy between one’s perceived self-image and ideal body image (“perceived–ideal discrepancy”). The present study evaluated the relationships between body-image disturbance and characteristics of eating disorders such as symptoms and related personality traits. In a psychophysiological experiment, female university students (mean ± SD age = 21.0 ± 1.38 years) were presented with silhouette images of their own bodies that were distorted in terms of width. The participants were asked whether each silhouette image was more overweight than their actual or ideal body images. Eating-disorder characteristics were assessed using six factors from the Japanese version of the Eating Disorder Inventory 2 (EDI2). We found that perceived–actual discrepancies correlated with negative self-evaluation (i.e., factor 3 of the EDI2), whereas perceived–ideal discrepancies correlated with dissatisfaction with one’s own body (i.e., factor 2 of EDI2). These results imply that distinct psychological mechanisms underlie the two components of body-image disturbance.

The neural correlates of \"self\" identified by neuroimaging studies differ depending on which aspects of self are addressed. Here, three categories of self are proposed based on neuroimaging findings and an evaluation of the likely underlying cognitive processes. The physical self, representing self-agency of action, body-ownership, and bodily self-recognition, is supported by the sensory and motor association cortices located primarily in the right hemisphere. The interpersonal self, representing the attention or intentions of others directed at the self, is supported by several amodal association cortices in the dorsomedial frontal and lateral posterior cortices. The social self, representing the self as a collection of context-dependent social-values, is supported by the ventral aspect of the medial prefrontal cortex and the posterior cingulate cortex. Despite differences in the underlying cognitive processes and neural substrates, all three categories of self are likely to share the computational characteristics of the forward model, which is underpinned by internal schema or learned associations between one's behavioral output and the consequential input. Additionally, these three categories exist within a hierarchical layer structure based on developmental processes that updates the schema through the attribution of prediction error. In this account, most of the association cortices critically contribute to some aspect of the self through associative learning while the primary regions involved shift from the lateral to the medial cortices in a sequence from the physical to the interpersonal to the social self.

Mutual help is common in human society, particularly during a disaster. The psychological processes underlying such social support are of interest in social and evolutionary psychology, as well as in the promotion of community resilience. However, research in terms of personality factors or support types is sporadic and has yet to address actual emergency situations. In this study, we analyzed survey data from survivors of the 2011 Tohoku earthquake and tsunami. The data included five types of social support occurring during the evacuation from a potential tsunami area: providing and receiving actual help and oral encouragement, as well as perceived support. The personality factor items included the Big Five dimensions and eight \"power to live\" factors, which were identified as advantageous for survival during this disaster. While none of the Big Five dimensions were associated with social support, six of the power to live factors were. Altruism, problem solving, etiquette, and self-transcendence contributed to the provision of actual help. Leadership and active well-being contributed to oral encouragement with the latter contributing also to perceived support. The findings were largely consistent with the literature in a non-emergency context. The relevance of the majority of these pro-survival personality factors to social support appeared to support the view that the propensity to cooperate in service of human survival in a disaster situation is primarily a social, rather than an individual, phenomenon, and encourages research on the mechanisms underlying how personality factors provide a benefit to both the individual and their community.

Hedonic goods are goods that people buy to obtain emotional experiences, such as joy or excitement, while utilitarian goods are bought to meet functional or instrumental needs. Although research in neuroscience suggests that the values of hedonic and utilitarian goods are similarly represented, it remains largely unknown how these values are mapped during purchasing decisions or task-irrelevant judgments. It has been suggested that people rely more on hedonic (vs. utilitarian) factors when making task-irrelevant judgments, and that this is amplified by trait-reward seeking. Functional magnetic resonance imaging (fMRI) can directly measure the mental processes involved in explicit or task-irrelevant value judgments. Using fMRI, we found that the explicit value of hedonic and utilitarian goods was commonly processed in the ventral striatum. In contrast, no significant results were obtained in common neural processing of task-irrelevant hedonic and utilitarian value. Additionally, we did not find any evidence that trait-reward seeking modulates task-irrelevant hedonic (vs. utilitarian) value processing. Our findings show that the value of both hedonic and utilitarian goods is commonly represented in the ventral striatum, and indicate that the value construct underlying consumer purchases is unidimensional.

Self-aid and mutual assistance among victims are critical for resolving difficulties in the immediate aftermath of a disaster, but individual facilitative factors for such resolution processes are poorly understood. To identify such individual factors in the background (i.e., disaster damage and demographic) and personality domains considering different types of difficulty and resolution, we analyzed survey data collected in the 3-year aftermath of the 2011 Great East Japan Earthquake and Tsunami. We first identified major types of difficulty using a cluster analysis of 18 difficulty domains and then explored individual factors that facilitated six types of resolution (self-help, request for help, help from family, help from an acquaintance, help through cooperation, and public assistance) of these difficulty types. We identified general life difficulties and medico-psychological difficulties as two broad types of difficulty; disaster damage contributed to both types, while some personality factors (e.g., neuroticism) exacerbated the latter. Disaster damage hampered self-resolution and forced a reliance on resolution through cooperation or public assistance. On the other hand, some demographic factors, such as being young and living in a three-generation household, facilitated resolution thorough the family. Several personality factors facilitated different types of resolution, primarily of general life difficulties; the problem-solving factor facilitated self-resolution, altruism, or stubbornness resolutions through requests, leadership resolution through acquaintance, and emotion-regulation resolution through public assistance. Our findings are the first to demonstrate the involvement of different individual, particularly personality, factors in survival in the complex social dynamics of this disaster stage. They may contribute to disaster risk mitigation, allowing sophisticated risk evaluation and community resilience building.

Emotion plays important and diverse roles across various social relations. Although the social functions of emotion have attracted increased attention, the effects of positive emotions such as pride on impression formation remain poorly understood. Drawing on social projection theory, this study examined how incidental experiences of pride influenced the impressions of those who made a blunder, along with two other characteristics: the person's warmth and competence. Participants were designated randomly to receive inductions of pride, awe, or a neutral emotion. Subsequently, they were asked to indicate their own impression of a person who had made a blunder and to rate their overall sense of that individual's warmth and competence. A laboratory experiment recruiting university students (Study 1, N = 79) demonstrated that pride, a positive emotion elicited by a self-relevant achievement, led to higher competency evaluations of others. However, a pre-registered online experiment in middle-aged adults (Study 2, N = 108) failed to replicate the effects of pride on competency evaluations of others. Furthermore, another pre-registered online experiment in younger adults (Study 3, N = 290) did not show successful manipulation of incidental emotions. These results suggest that strictly controlled experimental settings that induce robust incidental emotions might be better for demonstrating a strong pride effect on the evaluation of others.
