Attentional bias towards angry faces in trait-reappraisal

Emotion regulation (ER) strategies differ in when and how they influence emotion experience, expression, and concomitant cognition. However, no study to date has directly compared cognition in individuals who have a clear disposition for either cognitive or behavioural ER strategies. The present study compared selective attention to angry faces in groups of high trait-suppressors (people who are hiding emotional reactions in response to emotional challenge) and high trait-reappraisers (people who cognitively reinterpret emotional events). Since reappraisers are also low trait-anxious and suppressors are high trait-anxious, high and low anxious control groups, both being low in trait-ER, were also included. Attention to angry faces was assessed using an emotional dot-probe task. Trait-reappraisers and high-anxious individuals both showed attentional biases towards angry faces. Trait-reappraisers’ vigilance for angry faces was significantly more pronounced compared to both trait-suppressors and low anxious controls. We suggest that threat prioritization in high trait-reappraisal may allow deeper cognitive processing of threat information without being associated with psychological maladjustment.     

Insufficient augmentation of ambient GABA responsible for age-related cognitive deficit

Age-related degeneration of intracortical inhibition could underlie declines in cognitive function during senescence. Based on a hypothesis that a decrease in basal concentration of ambient (extrasynaptic) GABA with aging leads to depressing intracortical inhibition, we investigated how the basal concentration affects stimulus-evoked activity (as signal), ongoing-spontaneous activity (as noise) of neurons and their (signal-to-noise) ratio S/N. We simulated a neural network model equipped with a GABA transport system that regulates ambient GABA concentration in a neuronal activity-dependent manner. An increase in basal concentration augmented ambient GABA, increased GABA-mediated inhibitory current, and depressed ongoing-spontaneous activity while still keeping stimulus-evoked activity. This led to S/N improvement, for which it was necessary for the reversal potential of GABA transporter to be close to the resting potential of neurons. Above the resting potential, ongoing-spontaneous activity was predominantly enhanced due to excessive GABA-uptake from the extracellular space by transporters. Below the resting potential, stimulus-evoked activity was predominantly depressed, caused by excessive GABA-release. We suggest that the insufficient augmentation of ambient GABA due to a decrease in its basal concentration may be one of the possible causes of cognitive deficit with aging, increasing ongoing-spontaneous neuronal activity as noise. GABA transporter may contribute to improving S/N, provided that its reversal potential is close to the resting potential.     

Modality of postural movement in men and women with both arms flexed during standing.

We investigated postural movement associated with bilateral arm flexion in response to a light signal during standing in 179 healthy men and women to assess whether individual and sex differences arc evident in the postural movement pattern. The following results were obtained. (a) A correlation of -.87 was noted between movement angles of the foot-leg and leg-trunk. (b) Individual differences in movement angle were approximately twice as large in the hip joint as in the ankle and knee joints, and the movement angle of the leg trunk showed approximately half the number of extension as flexion movements. (c) The postural movement pattern was categorized on the basis of the movement angle of the foot leg and leg trunk into the following three patterns: hip flexion, backward leaning, and hip extension. The percentages of subjects showing these patterns were 59.2%, 33.5%, and 7.3%, respectively. (d) The inclination angle reflecting the righting response showed a gradual increase in size in the order of trunk, head, and neck. However, the righting response was not controlled precisely enough to enable subjects to maintain the inclination angle in a quiet standing posture. (e) We identified a significant sex difference in the relative frequency of subjects in the postural movement pattern.     

Perceptibility of body position in anteroposterior direction while standing with eyes closed.

The perception of body position in the anteroposterior direction was investigated by evaluating the reproducibility of the position from a quiet standing posture to forward or backward leaning posture with eyes closed. The subjects were 10 healthy male undergraduates, aged 20 to 28 years. The standing position was represented by the pressure center of the foot, which was shown by the relative distance (%) from the heel to the length of the foot. The reference positions of the pressure center of the foot were set at 10% increments from 20 to 80% of the length of the foot. The subjects attempted to reproduce each reference position 10 times, and the absolute and constant errors of the reproduced position were analyzed. The absolute errors at reference positions of 30 to 60% were distinctly larger than those at the other reference positions. This indicated that the perception of standing positions from 30 to 60% was less accurate. The constant errors at the reference positions of 40 to 60% were significantly positive, which meant that the reproduced position was located farther forward than the reference position.

Reconsidering the concept of theodicy in the context of the post-2011 Japanese earthquake and tsunami

Has the 2011 Tohoku Earthquake given rise to theodicy in Japan? This question would puzzle many scholars of religion for two major reasons. First, theodicy has generally been regarded as an outdated concept, and it is rare to see a lively discussion of it in today's academia except for in theology. Second, typical theodicean questions are unlikely to be asked publicly in Japan, where less than 2 percent of the population follow monotheistic traditions. Despite these assumptions, this article not only reports that ‘apparently’ theodicean public discourses have emerged since the 11 March earthquake, but also attempts to employ the typology of theodicy to analyze them in a thought-provoking and critical manner. It argues that the post-3/11 Japanese voices, which regard the disaster as a divine punishment, use a reverse logic of traditional Western theodicy. Rather than signaling a sudden turn to monotheism, the voices are inclined to imply nativism.     

The reception of Otto and Das Heilige in Japan: in and outside the phenomenology of religion

ABSTRACT

In Japan, Rudolf Otto is commonly identified as a precursor of the phenomenology of religion, claiming the sui generis nature of religion. However, the first Japanese translation of Das Heilige was published in 1927, far before the reception of the phenomenology of religion. This article divides the history of the reception of Das Heilige into three periods: before, during and after the heyday of the phenomenology of religion. It also examines both academic and lay receptions of Otto’s work, considering that its paperback version has sold over 53,000 copies. Its major findings are scholars of religion in the pre-war period framed Das Heilige according to a hierarchical dichotomy of the East and the West; post-war, phenomenological scholars empathetically interpreted the work, rejecting this ideological dichotomy; younger scholars have recently attempted more history-conscious, critical analyses; and, largely ‘non-religious’ general readers viewed it as a classic of Western thought, without being disturbed by its claim of Christian superiority.     

Gender differences in synchrony: Females in sync during unstructured dyadic conversation

Although previous studies have reported that individual prosocial traits generally enhance synchrony, gender as a social factor was not the subject of focus. The present study examined gender differences in synchrony by conducting three experiments on dyadic unstructured conversations with same-gender strangers. Synchrony was assessed by calculating the cross-wavelet coherence and determining the relative phase. As expected, through the three experiments, the female dyads showed a higher degree of synchrony, compared to the male dyads. Moreover, the conversation type (i.e., structured monologue vs. unstructured dialogue) did not moderate the gender effect (Experiment 2), while synchrony in the female dyads was influenced by the preceding conversation (Experiment 3). In contrast, through the three experiments, the role of the relative phase was unclear. The findings indicate that the social factor, gender, has an impact on synchrony, and that interpersonal sensitivity contributes to synchrony.
