RESUMEN

The sustainable development goals (SDGs) are required to be achieved by 2030, and measurement indicators are needed to properly visualize individual efforts toward SDGs. Here, we developed a Japanese version of the Sustainability Consciousness Questionnaire (SCQ), the most well-known individual measure of SDGs, and examined its reliability and validity. Three online surveys were conducted with 1,268 Japanese adults. The results of confirmatory factor analysis showed that the Japanese version of the SCQ consists of two single-level factors: sustainability knowingness/attitude and sustainability behavior. These two factors demonstrated sufficient internal consistency by Cronbach's alpha and McDonald's omega coefficient, which ensured measurement reliability. Additionally, cocorrelations with other scales indicated that the higher the level of sustainability knowledge and attitude, the less positive attitude toward climate change and the higher the level of sustainability behavior, indicating the construct validity of these factors. These results indicate that the Japanese version of the SCQ is reliable and valid.

RESUMEN

Human functional brain imaging research over the last 2 decades has shown that data from resting-state brain activity can help predict various psychological and pathological variables and brain function during tasks. However, most variables have been attributed to the individual brain. Recently, several studies have aimed to understand interpersonal relationships based on inter-individual similarity or dissimilarity of functional connectome. In this commentary, we introduce the studies that have opened up a new era of interpersonal research using human brain imaging.

RESUMEN

Background: The negative impacts of the coronavirus disease 2019 (COVID-19) pandemic have worsened the quality of therapy, psychological condition, and work life of second-line healthcare workers and occupational therapists (OTs). However, no study has investigated whether the impact of COVID-19 varies among OTs working in different fields. This study aimed to investigate the differences on the impact of COVID-19 between OTs in the physical and mental health fields. Methods: A cross-sectional online survey was conducted in Japan between January 20 and January 25, 2021. A total of 4,418 registered OTs who were members of the Japanese Association of Occupational Therapists volunteered for this study. After screening using the exclusion criteria, 1,383 participants were classified into two groups based on their field (mental health and physical health), and their quality of therapy, psychological condition, and work life were analyzed. Results: OTs in the mental health field showed a greater decrease in therapy quality and increase in workload and a lower rate of decrease in working hours than those in the physical health field. In the multinomial logistic regression analysis, decreased and increased therapy quality and decreased therapy quality were significantly associated with depression in the physical health field, and decreased therapy quality was associated with insomnia in the mental health field. Furthermore, insomnia and anxiety were commonly associated with increased workload and working hours, respectively, in both fields, whereas anxiety and depression were associated with increased workload only in the physical health field. Conclusions: These results demonstrate that COVID-19 differently impacted quality of treatment, workload, work time, and psychological condition in the physical and mental health fields; moreover, the relationships among these are different in these two fields. These results highlight the importance of investigating the field-specific negative impacts of COVID-19 on OTs and may provide helpful information for devising tailored and effective prevention and intervention strategies to address these challenges.

RESUMEN

Own-age bias is a well-known bias reflecting the effects of age, and its role has been demonstrated, particularly, in face recognition. However, it remains unclear whether an own-age bias exists in facial impression formation. In the present study, we used three datasets from two published and one unpublished functional magnetic resonance imaging (fMRI) study that employed the same pleasantness rating task with fMRI scanning and preferential choice task after the fMRI to investigate whether healthy young and older participants showed own-age effects in face preference. Specifically, we employed a drift-diffusion model to elaborate the existence of own-age bias in the processes of preferential choice. The behavioral results showed higher rating scores and higher drift rate for young faces than for older faces, regardless of the ages of participants. We identified a young-age effect, but not an own-age effect. Neuroimaging results from aggregation analysis of the three datasets suggest a possibility that the ventromedial prefrontal cortex (vmPFC) was associated with evidence accumulation of own-age faces; however, no clear evidence was provided. Importantly, we found no age-related decline in the responsiveness of the vmPFC to subjective pleasantness of faces, and both young and older participants showed a contribution of the vmPFC to the parametric representation of the subjective value of face and functional coupling between the vmPFC and ventral visual area, which reflects face preference. These results suggest that the preferential choice of face is less susceptible to the own-age bias across the lifespan of individuals.

RESUMEN

Introduction: The coronavirus disease of 2019 (COVID-19) has had a severe psychological impact on occupational therapists. Clarifying the mental health status of occupational therapists and its relationship with therapy quality is essential for maintaining the quality of care and patients' quality of life. Therefore, the present study aimed to investigate whether and how mental health problems are related to the quality of occupational therapy. Methods: A nationwide cross-sectional online survey was conducted during Japan's second national state of emergency (January 2021). A total of 4,418 registered occupational therapists who were members of the Japanese Association of Occupational Therapists participated in this study. After screening for the exclusion criteria, data from 1,966 participants were analyzed. Results: Path analysis showed that insufficient information provision by the workplace and increased workload were associated with depression, anxiety, and insomnia. Specifically, depression was associated with decreased therapy quality. Furthermore, one's therapy quality showed a strong positive correlation with colleagues' therapy quality. Discussion: These results demonstrated a direct link between therapists' mental health conditions and therapy quality and suggested that decreased therapy quality might occur at the institutional rather than individual level. A reassessment of the support system and prompt detection and support for professionals with psychological symptoms may be the key to enhancing therapy quality and patients' quality of life. The present results contribute to the understanding of these relationships, considering the current pandemic context for occupational therapists.

RESUMEN

IMPORTANCE: Coronavirus disease 2019 (COVID-19) has had a severe psychological impact on frontline and second-line medical workers. However, few empirical reports have been published on its impact on occupational therapists. Clarifying the mental health status of occupational therapists is important to maintain care quality and prevent psychological problems in this population. OBJECTIVE: To investigate the psychological impact of COVID-19 on Japanese occupational therapists in prefectures with and without severe pandemic-related restrictions and elucidate factors associated with psychological problems such as anxiety, depression, and insomnia. DESIGN: A cross-sectional online survey using region-stratified two-stage cluster sampling conducted May 28-31, 2020. PARTICIPANTS: The sample included 371 participants (63.1% women) in the prefectures under specific cautions (i.e., where residents were strictly advised to refrain from outings) and 1,312 in the prefectures without such cautions (61.9% women). RESULTS: The increase in workload due to the pandemic was significantly related to an increase in anxiety, depression, and insomnia, and an attempt to avoid talking face to face with others was significantly related to an increase in anxiety regardless of area. In prefectures under specific cautions as of May 25, 2020, the provision of sufficient information on COVID-19 by the workplace significantly reduced the risk of insomnia. In other prefectures, the provision of sufficient information significantly reduced the risk of depression. CONCLUSIONS AND RELEVANCE: These results demonstrate the severe negative psychological impact of the increase in workload resulting from COVID-19 and suggest the importance of psychological support for occupational therapists, such as the provision of sufficient information by the workplace. What This Article Adds: This study highlights the importance of providing psychological support for occupational therapists worldwide.

RESUMEN

Prediction of the initial compatibility of heterosexual individuals based on self-reported traits and preferences has not been successful, even with significantly developed information technology. To overcome the limitations of self-reported measures and predict compatibility, we used functional connectivity profiles from resting-state functional magnetic resonance imaging (fMRI) data that carry rich individual-specific information sufficient to predict psychological constructs and activation patterns during social cognitive tasks. Several days after collecting data from resting-state fMRIs, participants undertook a speed-dating experiment in which they had a 3-min speed date with every other opposite-sex participant. Our machine learning algorithm successfully predicted whether pairs in the experiment were compatible or not using (dis)similarity of functional connectivity profiles obtained before the experiment. The similarity and dissimilarity of functional connectivity between individuals and these multivariate relationships contributed to the prediction, hence suggesting the importance of complementarity (observed as dissimilarity) as well as the similarity between an individual and a potential partner during the initial attraction phase. The result indicates that the salience network, limbic areas, and cerebellum are especially important for the feeling of compatibility. This research emphasizes the utility of neural information to predict complex phenomena in a social environment that behavioral measures alone cannot predict.

RESUMEN

Our preferences are influenced by the opinions of others. The past human neuroimaging studies on social conformity have identified a network of brain regions related to social conformity that includes the posterior medial frontal cortex (pMFC), anterior insula, and striatum. Since these brain regions are also known to play important roles in reinforcement learning (i.e., processing prediction error), it was previously hypothesized that social conformity and reinforcement learning have a common neural mechanism. However, although this view is currently widely accepted, these two processes have never been directly compared; therefore, the extent to which they shared a common neural mechanism had remained unclear. This study aimed to formally test the hypothesis. The same group of participants (n = 25) performed social conformity and reinforcement learning tasks inside a functional magnetic resonance imaging (fMRI) scanner. Univariate fMRI data analyses revealed activation overlaps in the pMFC and bilateral insula between social conflict and unsigned prediction error and in the striatum between social conflict and signed prediction error. We further conducted multivoxel pattern analysis (MVPA) for more direct evidence of a shared neural mechanism. MVPA did not reveal any evidence to support the hypothesis in any of these regions but found that activation patterns between social conflict and prediction error in these regions were largely distinct. Taken together, the present study provides no clear evidence of a common neural mechanism between social conformity and reinforcement learning.

RESUMEN

Previous neuroimaging studies demonstrated that ventromedial prefrontal cortex (vmPFC) activity reflects how much an individual positively views each person (impression). Here, we investigated whether the degree to which individuals think others positively view them (reflected impression) is similarly tracked by activity in the vmPFC by using fMRI and speed-dating events. We also examined whether activity of the vmPFC in response to the faces of others would predict the impression formed through direct interactions with them. The task consisted of three sessions: pre-speed-dating fMRI, speed-dating events, and post-speed-dating fMRI (not reported here). During the pre-speed-dating fMRI, each participant passively viewed the faces of others whom they would meet in the subsequent speed-dating events. After the fMRI, they rated the impression and reflected impression of each face. During the speed-dating events, the participants had 3-min conversations with partners whose faces were presented during the fMRI task, and they were asked to choose the partners whom they preferred at the end of the events. The results revealed that the value of both the impression and reflected impression were automatically represented in the vmPFC. However, the impression fully mediated the link between the reflected impression and vmPFC activity. These results highlight a close link between reflected appraisal and impression formation and provide important insights into neural and psychological models of how the reflected impression is formed in the human brain.

RESUMEN

When individuals are forced to choose between similarly preferable alternatives, a negatively arousing cognitive conflict occurs, and the preference attitudes toward the chosen and rejected alternatives diverge. This phenomenon, often referred to as "cognitive dissonance", is of interest in psychological and decision neuroscience research. The dorsal anterior cingulate cortex (dACC) is involved in representing the cognitive conflict induced by difficult-choice tasks. Previous studies have shown age-related decline of the dACC function. However, whether the heightened activity of the dACC regarding cognitive conflict, and choice-induced preference change that behaviorally occur in young subjects also occur in the elderly is unclear. Furthermore, recent studies have noted substantial methodological flaw with the free-choice paradigm that often used in studies focusing on cognitive dissonance. Here, we used functional magnetic resonance imaging (fMRI) and a modified free-choice paradigm to formally test the effect of aging on choice-induced cognitive conflict. In the young participants, behavioral data confirmed the existence of cognitive conflict and preference change for the alternatives that they rejected in the difficult-choice trials. The imaging data revealed that the right dACC displayed an interaction effect associated with cognitive conflict. In contrast, we did not observe such effects in the elderly participants. These suggest a possibility that elderly people likely feel less cognitive dissonance.

RESUMEN

Previous findings have revealed abnormal visual attention or processing of faces among individuals with autism spectrum condition (ASC). However, little attention has been paid to the relationship between autistic traits and neural mechanisms associated with representing facial values. Using fMRI, we investigated the patterns of brain activity in the vmPFC and VS in response to faces of elderly males, elderly females, young males, and young females. During fMRI, subjects with a relatively high autism quotient (high group) and those with a relatively low autism quotient (low group) were presented with a face and asked to rate its pleasantness. After fMRI, the subjects were presented with pairs of faces and asked to select the face that they preferred. Our results indicate a dissociable modulatory effect of autistic traits on the vmPFC and VS: The vmPFC activity in the low group was more sensitive to age differences in female faces compared to that in the high group, whereas VS activity did not show differences between groups. These results suggest that, in the BVS, autistic traits selectively modulate the vmPFC activity associated with facial value representation.

RESUMEN

In many developed countries, the number of infants who experience non-parent childcare is increasing, and the role of preschool teachers is becoming more important. However, little attention has been paid to the effects of childcare training on students who are studying to become preschool teachers. We used functional magnetic resonance imaging (fMRI) to investigate whether and how childcare training affects brain responses to infants' facial expressions among young females studying to become preschool teachers. Twenty-seven subjects who attended a childcare training session (i.e., the experimental group) and 28 subjects who did not attend the training (i.e., the control group) participated in this study. The participants went through fMRI scanning twice: before and after the childcare training session. They were presented with happy, neutral, and sad infant faces one by one during fMRI scanning. The present neuroimaging results revealed that the activity patterns of the left superior temporal sulcus (STS) for sad faces were modulated by the interaction between the time point of the data collection and group differences. The present results are the first to highlight the effects of childcare training on the human brain.

RESUMEN

Interdependent self-construal refers to a view of the self as embedded in relationships with others. Prior work suggests that this construal is linked to a strong value placed on social obligations and duties. Interdependent people are therefore cognitively attuned to others and various social events in their surroundings while down-regulating their personal goals. In the present work, we examined whether structural properties of the brain predict interdependent self-construal. We performed a structural magnetic resonance imaging on 135 Japanese young adults while assessing (i) independent and interdependent self-construals and (ii) the degree to which individuals form vivid images of external objects (object imagery). The cortical volume of the orbitofrontal cortex (OFC) (a core cortical region responsible for value-based decisionmaking and, thus, inherently involved in personal goals and desires) inversely predicted interdependent self-construal. Further analysis found that the highest level of interdependent self-construal is achieved when those who are relatively low in the OFC volume are simultaneously high in object imagery, consistent with previous evidence that interdependence, as realized via obligation and duty, requires both the reduced self-interest and vigilant cognitive attunement to environmental context.

RESUMEN

Psychological studies have indicated that males exhibit stronger preferences for physical attributes in the opposite gender, such as facial attractiveness, than females. However, whether gender differences in mate preference originate from differential brain activity remains unclear. Using functional magnetic resonance imaging (fMRI), we investigated the patterns of brain activity in the ventromedial prefrontal cortex (vmPFC), a region critical for the valuation of faces, in response to elderly male, elderly female, young male, and young female faces. During fMRI, male and female subjects were presented with a face and asked to rate its pleasantness. Following fMRI, the subjects were presented with pairs of faces and asked to select the face that they preferred. We analyzed the vmPFC activity during the pleasantness-rating task according to the gender of the face stimulus (male and female) and the age of the face stimulus (elderly and young). Consistent with the results of previous studies, the vmPFC activity parametrically coded the subjective value of faces. Importantly, the vmPFC activity was sensitive to physical attributes, such as the youthfulness and gender of the faces, only in the male subjects. These findings provide a possible neural explanation for gender differences in mate preference.

RESUMEN

Destination memory is the process of remembering to whom we tell particular things. Although recent behavioral studies have clarified the cognitive nature of destination memory, the neural mechanisms underlying destination memory retrieval remain unclear. We used functional magnetic resonance imaging (fMRI) to determine whether the medial temporal lobe (MTL), a structure that has been implicated in recollection-based memory, is activated during the successful retrieval of destination information. During a study phase before fMRI scanning, the subjects told a series of facts to either a woman or a man. During fMRI scanning, the subjects were asked to judge whether each fact presented was old or new, and if they judged it as old, to indicate, including a confidence rating (high or low), whether the subjects had told that fact to either a man or a woman. We found that successful destination retrieval, when compared to failed destination retrieval, was associated with increased activity in the parahippocampal gyrus. We also found that the confidence level (high vs. low) for destination memory retrieval was associated with increased activity in another (posterior) region of the parahippocampal gyrus. The present study suggests that the successful retrieval of destination information depends highly on MTL-mediated recollection processes.

RESUMEN

Accumulating evidence has shown the profound influence of social reputation on human behavior and has implicated the ventromedial prefrontal cortex (vmPFC) in representing subjective values induced by social interaction. However, little is known regarding how the vmPFC encodes subjective pleasantness induced by social reputation received from others. We used functional magnetic resonance imaging (fMRI) to investigate how the vmPFC in males and females encodes the subjective pleasantness of social reputation received from the same gender and from the opposite gender. Behavioral data showed that positive reputation was perceived to be more pleasant than negative reputation. Intriguingly, both male and female subjects showed greater differences in the pleasantness scores between the positive reputation condition and the negative reputation condition from females than between positive and negative reputations from males. Imaging data revealed that the left vmPFC specifically contributed to the processing of positive reputation. The activity patterns of the vmPFC corresponded to the gender differences in behavior during the processing of social reputation. These results indicate that the vmPFC plays a role in representing the subjective value of positive social reputation and that this region might be a final computational site in a stream of value-based decision-making processes.

RESUMEN

Recent neuroimaging studies have investigated the neural substrates involved in the valuation of supraliminally presented targets and the subsequent preference decisions. However, the neural mechanisms of the valuation of subliminally presented targets, which can guide subsequent preference decisions, remain to be explored. In the present study, we determined whether the neural systems associated with the valuation of supraliminally presented faces are involved in the valuation of subliminally presented faces. The subjects were supraliminally and subliminally presented with faces during functional magnetic resonance imaging (fMRI). Following fMRI, the subjects were presented with pairs of faces and were asked to choose which face they preferred. We analyzed brain activation by back-sorting the fMRI data according to the subjects' choices. The present study yielded two main findings. First, the ventral striatum and the ventromedial prefrontal cortex predict preferences only for supraliminally presented faces. Second, the dorsomedial prefrontal cortex may predict preferences for subliminally presented faces. These findings indicate that neural correlates of the preference-related valuation of faces are dissociable, contingent upon whether the subjects consciously perceive the faces.

RESUMEN

We conducted a functional magnetic resonance imaging (fMRI) study to elucidate the neurocognitive mechanisms of harmful and helpful dishonest decisions. During scanning, the subjects read scenarios concerning events that could occur in real-life situations and were asked to decide whether to tell a lie as though they were experiencing those events. Half of the scenarios consisted of harmful stories in which the dishonest decisions could be regarded as bad lies, and the other half consisted of helpful stories in which the dishonest decisions could be regarded as good lies. In contrast to the control decision-making task, we found that the decision-making tasks that involved honesty or dishonesty recruited a network of brain regions that included the left dorsolateral prefrontal cortex. In the harmful stories, the right temporoparietal junction and the right medial frontal cortex were activated when the subjects made dishonest decisions compared with honest decisions. No region discriminated between the honest and dishonest decisions made in the helpful stories. These preliminary findings suggest that the neural basis of dishonest decisions is modulated by whether the lying serves to harm or help the target.
