We investigated the relationship between attentional resources and pedaling cadence using electroencephalography to measure P300 amplitudes and latencies. Twenty-five healthy volunteers performed the oddball task while pedaling on a stationary bike or relaxing. We set them four conditions, namely, performing only the oddball task, performing the oddball task while pedaling at optimal cadence, performing the oddball task while pedaling faster than optimal cadence, and performing the oddball task while pedaling slower than optimal cadence. P300 amplitudes at Cz and Pz electrodes (...) under optimal, fast, and slow conditions were significantly lower than those under control conditions. P300 amplitudes at Pz under fast and slow conditions were significantly lower than those under the optimal condition. No significant changes in P300 latency at any electrode were observed under any condition. Our findings revealed that pedaling at non-optimal cadence results in less attention being paid to external stimuli compared with pedaling at optimal cadence. (shrink)

Velina Hasu Houston’s theatrical representations focus on exploring cultural collision and coalescence in transnational communities. With her biographical and cultural background deeply influenced by her Japanese mother’s way of life and sense of values, Houston has been open-minded in creating a new viewpoint through which to look at Japan, the United States and the world. Calligraphy is quite challenging in that it looks at her mother’s aging from both Japanese and American perspectives. It sheds new light on not only understanding (...) the beauty in the aging process but also women’s memories that have value beyond the personal. Since she wrote Tea based on her mother’s life as a war bride, Houston has presented a pioneering, in-depth exploration of Asian women’s memories that have been historically ignored in the United States. This paper examines how Houston’s insight into transnationalism through the transformative nature of cultural identity and change inspires her to re-envision women’s writing and highlights the need for a re-examination of the power of love and beauty.

Previous studies have suggested that auditory hallucination is closely related to thought insertion. In this study, we investigated the relationship between the external misattribution of thought and auditory hallucination-like experiences. We used the AHES-17, which measures auditory hallucination-like experiences in normal, healthy people, and the Deese–Roediger–McDermott paradigm, in which false alarms of critical lure are regarded as spontaneous external misattribution of thought. We found that critical lures elicited increased the number of false alarms as AHES-17 scores increased and that scores (...) of AHES-17 predicted the rate of false memory of critical lures. Furthermore, we revealed that the relationship between AHES-17 scores and the rates of false alarms to critical lures was strictly linear. Therefore, it might be said that individual differences in auditory hallucination-like experiences are highly related to the external misattribution of thought. We discussed these results from the perspective of the sense of agency over thought. (shrink)

We investigated output-monitoring errors over speech based on findings in the research on the sense of agency. Several words were presented one-by-one, and we asked participants to say the word aloud, mouth the word, or imagine saying the word aloud. Later, participants were asked whether each word was said aloud. We found that the “said aloud” response was higher for generated words than that for observed words; it was decreased when the pitch of the feedback was lowered but still higher (...) than when no feedback was received, and it was the same when no feedback was received and when feedback was replaced by another’s voice. Furthermore, we found that the “said aloud” response did not decrease even when the altered feedback was received with a short delay. These results were discussed according to the sense of agency and agency memory. (shrink)

BackgroundMany genetic counseling studies have focused on anxiety status because clients of GC often feel anxious during their visits. Metacognition is known to be one of the causes of having an inappropriate thinking style. In this study, we examined the relationship between anxiety and the metacognitive status of GC clients according to their characteristics.MethodsThe participants were 106 clients who attended their first GC session in our hospital from November 2018 to March 2021. The survey items were the clients’ characteristics, anxiety (...) status at the time of the visit, and metacognitive status.ResultsHigh state anxiety and high trait anxiety were observed in 34.9 and 11.3% of clients, respectively. Clients who were a relative or had a family history were significantly more likely to have high state anxiety. As for metacognitive status, only negative beliefs about thoughts concerning uncontrollability and danger were associated with having an anxiety status. Furthermore, multivariate analysis showed that negative beliefs about thoughts concerning uncontrollability and danger were an independent determinant of higher state anxiety, but not being a relative or having a family history. Metacognitive status scores were significantly lower in clients than in the control group.ConclusionState anxiety was shown to be more dependent on negative beliefs about thoughts concerning uncontrollability and danger of GC clients than their characteristics such as being a relative or having a family history. The results of this study will contribute to the development of new GC psychosocial support measures to address the anxiety of GC clients. (shrink)

There are different ways of defining science, but I should like to examine it primarily as one of the forms of mental labor. In this connection it is appropriate to recall Marx's words: "A distinction must be made between universal labor and cooperative labor. Each plays its own role in the process of production. They overlap, but there is also a distinction between them. Every scientific work, every discovery, every invention is universal labor. It is made possible partly by cooperation (...) among contemporaries and partly by making use of the work of those who have gone before. Joint labor presumes direct cooperation among individuals." What is subsumed here under "cooperative labor," according to Marx, is "directly associated labor," which, to put it in other terms, is "direct labor.". (shrink)

This article presents research on robot therapy for elderly residents in a care house. Experiments were conducted from June 2005, lasting more than 2 months. Two therapeutic baby seal robots were introduced to the residents, and activated for over 9 hours daily. To investigate the psychological and social effects of the robots, the residents’ activities in public areas were recorded using video cameras, during the daytime for over 2 months. In addition, urinalysis of the residents was performed for 17-ketosteroid sulfate (...) and 17-hydroxycorticosteroid. Results of the video analysis indicated that social interaction increased through interaction with the seal robots. Results of the urine tests showed that the reactions of the subjects’ vital organs to stress improved after the introduction of the robots. (shrink)

Background. Positive schizophrenic symptoms, especially passivity phenomena, including auditory hallucinations, may be caused by an abnormal sense of agency, which people with schizotypal personality traits also tend to exhibit. A sense of agency asserts that it is oneself who is causing or generating an action. It is possible that this abnormal sense of self-agency is attributable to the abnormal prediction of one’s own movements in motor control. Method. We conducted an experiment using the “disappeared cursor” paradigm in which non-clinical, healthy (...) participants were required to click on a target using an invisible mouse cursor. Prediction error was defined as the distance between the target and the click point. Results. The results showed that schizotypal personality traits, but not depressive or anxious traits, were correlated with deficits in predicting movements of the subjects’ left hand. In particular, auditory hallucination proneness had the strongest relationship with movement prediction error. In this report, we also discuss the error tendency. Conclusions. This finding is in accordance with the idea that passivity phenomena or proneness may be caused by the abnormal prediction of one’s own actions or movements. (shrink)

Mutations in growth factor receptor signaling pathways are common in cancer cells, including the highly lethal brain tumor glioblastoma (GBM) where they drive tumor growth through mechanisms including altering the uptake and utilization of nutrients. However, the impact of changes in micro‐environmental nutrient levels on oncogenic signaling, tumor growth, and drug resistance is not well understood. We recently tested the hypothesis that external nutrients promote GBM growth and treatment resistance by maintaining the activity of mechanistic target of rapamycin complex 2 (...) (mTORC2), a critical intermediate of growth factor receptor signaling, suggesting that altered cellular metabolism is not only a consequence of oncogenic signaling, but also potentially an important determinant of its activity. Here, we describe the studies that corroborate the hypothesis and propose others that derive from them. Notably, this line of reasoning raises the possibility that systemic metabolism may contribute to responsiveness to targeted cancer therapies. (shrink)

While people are still alive, we owe them respect. Yet what, if anything, do we owe the newly dead? This question is an urgent practical concern for aged societies, because older people die at higher rates than any other age group. One novel way in which Japan, the frontrunner of aged societies, meets its need to accommodate high numbers of newly dead is itai hoteru or corpse hotels. Itai hoteru offer families a way to wait for space in over‐crowded crematoriums (...) while affording an environment conducive to grieving. Drawing on conversations with itai hoteru employees, we delineate the values this contemporary death practice expresses and show how these values comprise part of the broader idea of a good death. A good death implies duties on both sides of death's divide: to both the dying and the newly dead. (shrink)

Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

The atomic structure of a ‡ = 3, [110]/{112} grain boundary in a yttria-stabilized cubic zirconia bicrystal has been investigated by high-resolution transmission electron microscopy . It was found that the grain boundary migrated to form periodic facets, although the bicrystal was initially joined so as to have the symmetric boundary plane of {112}. The faceted boundary planes were indexed as {111}/{115}. The structure of the {111}/{115} grain boundary was composed of an alternate array of two types of structure unit: (...) {112}- and {111}-type structure units. HRTEM observations combined with lattice statics calculations verified that both crystals were relatively shifted by [110] along the rotation axis to form a stable grain-boundary structure. A weak-beam dark-field image revealed that there was a periodic array of dislocations along the grain boundary. The grain-boundary dislocations were considered to be introduced by the slight misorientation from the perfect ‡ = 3 orientation. The fact that the periodicity of the facets corresponded to that of the grain-boundary dislocations must indicate that the introduction of the grain-boundary dislocations is closely related to the periodicity of the facets. An atomic flipping model has been proposed for the facet growth from the initial ‡ = 3, {112} grain boundary. (shrink)
