Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

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.

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.

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.

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.

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.

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.

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.

Coronavirus disease 2019 (COVID-19) has a profound impact on our society, and health care professionals are challenged by the present outbreak. A recent study showed that a significant proportion of second-line workers and frontline workers experienced psychological distress. Although these findings suggest the possibility that rehabilitation therapists, especially those who work at the hospital, experience psychological distress, their mental health state has been largely dismissed and the number of an evidence-based practice is limited. Here, we discuss the importance of focusing on the mental health of therapists by introducing studies that focus on the mental health of health care workers during the COVID-19, SARS, and H1N1 influenza pandemics. We then noted the need to track the dynamic relationship between the mental health of therapists and the COVID-19 pandemic by employing longitudinal data collection with psychological measures that reliably and validly capture the mental health of therapists. This approach would be effective for preparation for future pandemics, as we have learned much from previous pandemics. We hope that our Tutorial Note will help readers who are interested in the mental health of rehabilitation therapists and encourage future studies.

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.

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.

   We performed rehabilitation for a female patient with apperceptive visual agnosia and impaired semantic memory after cerebral hypoxia. Three types of training were performed in series : 1) visual search and discrimination, 2) colored picture matching, 3) errorless learning of identification after enumerating visual features of objects. After the training, she became able to search and discriminate the stimuli quickly and systematically. This effect was maintained in follow-up. Her performance of colored picture matching improved, generalized to include other colored pictures, and was maintained in follow-up. Her visual identification of the objects used in the training also improved, and part of the improvement was maintained in follow-up. On the other hand, visual identification of new objects which were not used in the training did not improve. <br>   However, she became accustomed to identifying objects after enumerating the visual features of objects in her daily life, and this habit improved her recognition of each object, after sufficient repetition. These results suggest that this training is available when we select objects having important roles in the daily life of the patient.

In the present study, we investigated whether brain activity during the presentation of other people's faces and impression ratings of those faces predicted the actual impressions that people would have when they talked to others in face-to-face situation, using functional magnetic resonance imaging (fMRI). The results showed that pre-recorded impression ratings of the other person's face significantly predicted impressions of the actual conversation with that person, while the brain activity for each face obtained during the fMRI task did not significantly predict impressions of others during the conversation task.

In the present study, we have investigated neural mechanisms associated with preference formation for faces that are repeatedly presented in supraliminal or subliminal fashion, by combining functional magnetic resonance imaging (fMRI) and a technique called mere exposure paradigm. We found that the orbitofrontal cortex, ventral striatum, and early visual cortices are associated with supraliminal mere exposure effect, whereas the dorsomedial prefrontal cortex and anterior cingulate cortex are associated with subliminal mere exposure effect.

高齢者における顔の価値表象に関わる神経機構の検討について、本年度は機能的磁気共鳴画像法（functional magnetic resonance imaging: fMRI）により得られた脳活動データの解析を終了し、論文執筆の最終段階に入ることができた。脳活動データの解析から、高齢者においても腹内側前頭前野が他者の顔の価値表象に重要な役割を果たしていることが明らかとなったが、加齢の効果には性差が認められた。具体的には、高齢女性よりも高齢男性で加齢の効果が顕著であることが明らかとなった。また、本年度は他者の顔に対する価値表象機構の検討に関連し、腹内側前頭前野と背内側前頭前野の機能的役割が意識的に顔を見ることができる場合と、意識的には顔を見ることができない場合で異なることを報告した（Ito et al., Human Brain Mapping, DOI: 10.1002/hbm.22813）。具体的には、腹内側前頭前野は意識的に顔を見ることができる場合のみに、選好を反映する価値表象を行っている一方で、背内側前頭前野は意識的に顔を見ることができない場合のみに、選好を反映する価値表象を行っていることが明らかとなった。これらの知見は、顔の価値表象に関わる神経機構が、①生物学的な要因によって変容すること、②呈示された顔を意識できるかどうかによって、腹内側前頭前野と背内側前頭前野が独立に価値を表象し、選好を反映している可能性を示唆するものである。ここまでの検討に予想以上の時間を要したため、自閉症者を対象とした実験は実施できなかったが、今回明らかになった知見は、今後の研究の発展にに資するものであったと考えられる。
