Individuals with high anxiety have a specific tendency to update beliefs based on the given information in ambiguous situations. However, it is unclear what aspect of information evaluation is specific in individuals with high anxiety. We explored the factor of these changes by applying the Bayesian update to the bead task. In the task, we presented two bins containing beads of two different colors in different proportions. Each time a bead was presented, they reported a subjective belief about the bin from which the beads were extracted. In the analysis, we assumed that the current confidence was obtained by adding the information of the current bead to the confidence at the previous time point. We then estimated whether individuals were more evaluated on the previous confidence or the current information. The results showed that individuals with high anxiety underestimated the information obtained from the current bead.

A relationship between the awareness of mind-wandering (MW) and the disruption of MW because of external stimuli has previously been reported. Attention often fluctuates without external stimuli and such disruptions can spontaneously precede awareness of MW. To elucidate whether changes in attentional resources used by MW exist, we used event-related potentials (ERPs), focusing on the P300 (P3) ERP component as an index of attention to a task. Participants performed a simple task, in which they pressed a key in synchrony with continually presented tones. Moreover, they were asked to stop the response whenever they became aware of their MW. We analyzed the P3 induced by the tones before self-reports of MW using a state–space model that was used for analysis to detect changes over time. The results revealed that the mean amplitude of P3 increased significantly from the third to the second tone before the self-reports; no other clear increasing or decreasing tendencies were observed. We concluded that the attentional resources allocated to the main task returned, suggesting that such awareness requires a decrease in resources to task-unrelated thoughts. These findings highlight a transitional state related to awareness between the MW state and self-reports. Therefore, the state immediately before self-reports should not be defined as merely an MW state when using the self-caught method.

[Dynamic Functional Connectivity in Resting-State fMRI and Its Clinical Applications].

The conventional analysis assumes a constant mental state during scanning and assesses the strength of functional connectivity as the average of the entire fMRI data. However, it is suggested that even at rest, functional connectivity may change with time, and the conventional analysis has not been able to fully evaluate its properties. To overcome this limitation, many studies propose an index called dynamic functional connectivity (dFC) or time-varying functional connectivity (TVFC) or the chronnectome. This article reviews the significance and methods of dFC, examples of its application in clinical studies, and its limitations. Finally, we discuss its potential for clinical application.

One's past behavior influences their present behavior. The effects of such response history have often been tested using response inhibition tasks. Since previous studies have highlighted the effect of immediate action history formed directly before the subsequent response in a laboratory environment, we aimed to elucidate the longer-term effects of response history, using repetitive and habitual consumer behavior in daily life as the response history. We used event-related potentials recorded in a Go/No-go task to investigate brain activity related to inhibitory control, hypothesizing that stimuli with a high frequency of choice in everyday life would elicit stronger inhibition-related activity, that is, the No-go-N2 component. Participants were asked to evaluate the frequency of purchase and use of some products, such as food and drink or social networking services (SNS) in everyday situations. Images of each product were assigned as stimuli in the Go and No-go trials according to the frequency of choice. The results showed that frequently purchased No-go stimuli yielded a larger amplitude of the No-go-N2 component and a negative shift between 200 and 300ms after the presentation of No-go stimuli. The results suggest that frequently chosen products evoke stronger inhibition conflicts and require greater cognitive control to withhold a response. Our findings showed that repeated purchase behavior in daily life forms a response history and has a long-term influence on the inhibition of even simple approaching behaviors, such as button pressing.

Effects of interoceptive accuracy in autonomic responses to external stimuli based on cardiac rhythm.

Interoceptive accuracy is an index of the ability to perceive an individual's internal bodily state, including heartbeat and respiration. Individual differences in interoceptive accuracy influence emotional recognition through autonomic nervous activity. However, the precise mechanism by which interoceptive accuracy affects autonomic reactivity remains unclear. Here, we investigated how cardiac reactivity induced by a non-affective external rhythm differed among individuals, using a heartbeat counting task. Because individuals with poor interoceptive accuracy cannot distinguish an external rhythm from their cardiac cycles, it has been hypothesized that the interoceptive effect on heart rate works differently in individuals with good interoceptive accuracy and those with poor interoceptive accuracy. Study participants observed a visual or auditory stimulus presented at a rhythm similar to the participants' resting heart rates. The stimulus rhythm was gradually changed from that of their resting heart rate, and we recorded electrocardiographs while participants were exposed to the stimuli. Individuals with good interoceptive accuracy exhibited a deceleration in heart rate when the rhythm of the auditory stimulus changed. In contrast, in the group with poor interoceptive accuracy, the heart rate decreased only when the stimulus became faster. They were unable to distinguish the rhythm of their own heartbeat from that of the external rhythm; therefore, we propose that such individuals recognize the stimuli at the pace of their heart rate. Individuals with good interoceptive accuracy were able to distinguish their heart rates from the external rhythm. A modality difference was not observed in this study, which suggests that both visual and auditory stimuli help mimic heart rate. These results may provide physiological evidence that autonomic reactivity influences the perception of the internal bodily state, and that interoception and the autonomic state interact to some degree.

The insular cortex is considered an important region for feeling emotions through interoception. Most studies that report the role of the insula in integrating interoception and emotion have used neuroimaging techniques such as functional magnetic resonance imaging (fMRI); however, there are limited neuropsychological studies. The effects of insular lesions on emotion and interoception have not been suitably investigated. In this study, we examined the role of the insular cortex in cardiac interoception and recognizing emotions from facial expressions by comparing them pre- and post-operatively in patients with glial tumors or brain metastases associated with the insular lobe. Although no significant difference in interoceptive accuracy was observed between the two phases, there were significant associations between the changes in interoceptive accuracy and sensitivity to expressions of anger and happiness. An increased error rate in the heartbeat counting task in the post-operation phase was associated with a decreased accuracy in recognizing anger and happiness. Since most patients had left insula lesions, generalizability of the findings to patients with right lesions is a future subject. To the best of our knowledge, this is the first study to examine the change in interoception and emotion after insular resection in humans. The study results indicate that removal of the insula affects the recognition of emotions such as anger and happiness through interoceptive processing.

<p>人の思考には時間（過去/未来），感情（ネガティブ/ポジティブ），自己/他者など様々な方向性があり，特に未来に関する思考のポジティブバイアスが多くの先行研究で示されている。しかしながら，それらは個人的な未来の想像を主な対象としており，他者の未来の想像でも同様のバイアスが生じるのかは明らかでない。本研究では，「私（彼）は／将来／試験に…」のように文手がかりを，主語，時間，内容の順に呈示し，自己または他者の未来について思考するよう参加者に求めた。このとき思考の感情価は参加者が任意に決定した。ポジティブ思考数がネガティブ思考数より多いことを以てポジティブバイアスとし，その傾向が自己に関する思考と他者に関する思考との間で異なるかどうか検討した。その結果，他者の遠い未来を想像するときにより強いポジティブバイアスが生じており，自己-他者間で異なる感情処理がなされていることが示唆された。</p><p></p>
