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.     

Meta-analysis using linear mixed models

Psychologists often use special computer programs to perform meta-analysis. Until recently, this had been necessary because standard statistical packages did not provide procedures for such analysis. This paper introduces linear mixed models as a framework for meta-analysis in psychological research, using a popular general purpose statisticalpackage, SAS. The approach is illustrated with three examples, usingsas peoc mixed.     

Parenting Self-Efficacy and Parental Involvement: Mediators or Moderators Between Socioeconomic Status and Children’s Academic Competence in Japan and Korea?

We examined the causes of a growing achievement gap associated with socioeconomic status (SES) in Korea and Japan, testing whether parenting self-efficacy (PSE) and parental involvement (PI) mediated or moderated the association of SES to children’s school-related competence (SRC). Three hundred and seventy-two Korean and 309 Japanese mothers of first- and second-grade children completed a parenting survey. Japanese mothers’ education and PSE were directly associated with SRC. PSE moderated the association of education to SRC, with higher PSE of college-educated mothers positively associated with SRC. In the Korean sample, household income was associated with SRC directly as well as indirectly through PSE.

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.
