Effectiveness of Group Positive Parenting Program (Triple P) in Changing Child Behavior,Parenting Style,and Parental Adjustment: An Intervention Study in Japan

The purpose of this study is to investigate the effectiveness of a group-based family intervention program known as the Group Positive Parenting Program (Triple P), with families in Japan. Reductions in children’s behavioral problems, changes in dysfunctional parenting practices, and affects on parenting adjustment were examined. Participants of both the intervention and control groups (N = 91 and N = 24, respectively) were recruited from mothers visiting health clinics in Kawasaki City, Kanagawa. Intervention and control groups were assessed in terms of child behavior (Strength and Difficulty Questionnaire, SDQ), parenting style (Parenting Scale, PS), and parenting adjustment (Depression-Anxiety-Stress Scale, DASS; and Parenting Experience Survey, PES), both pre- and postintervention. A repeated measures multivariate analysis of variance was used to determine the intervention’s effects. The SDQ score for the conduct problems subscale indicated a significant intervention effect. In addition, the postintervention scores for all subscales of the PS, the DASS depression subscale and total scores, as well as ratings for perceived difficulty of parenting in the PES, were significantly reduced in the intervention group alone. The PES also revealed that confidence in parenting significantly increased only in the intervention group. Group Triple P is effective in decreasing child conduct problems, dysfunctional parenting practices, depression, anxiety, stress, and the perceived level of parenting difficulty, as well as in improving parenting confidence, among Japanese families.     

Relative distance cues contribute to scaling depth from motion parallax

The visual system scales motion parallax signals with information about absolute distance (M. E. Ono, Rivest, & H. Ono, 1986). The present study was designed to determine whether relative distance cues, which intrinsically provide information about relative distance, contribute to this scaling. In two experiments, two test stimuli, containing an equal extent of motion parallax, were presented simultaneously at a fixed viewing distance. The relative distance cues of dynamic occlusion and motion parallax in the areas surrounding the test stimuli (background motion parallax) and/or relative size were manipulated. The observers reported which of the two parallactic test stimuli appeared to have greater depth, and which appeared to be more distant. The results showed that the test stimulus specified, by the relative distance cues, as being more distant was perceived as having more depth and as being more distant. This indicates that relative distance cues contribute to scaling depth from motion parallax by modifying the information about the absolute distance of objects.     

Perceptibility of large and sequential changes in somatosensory information during leaning forward and backward when standing

11 healthy young men served as subjects in two experiments on perceptibility of (1) large changes in foot pressure and muscle activity induced by body leaning and (2) sequential changes in pressure at the first toe and the head of the first metatarsalis when leaning forward. The effects of reduced sensitivity on that perceptibility were also studied by repeating the experiments while cooling localized plantar areas of the sole (the head of the first metatarsalis, the first toe, and the heel). Under the normal (noncooled) condition, all subjects accurately perceived maximum pressure at the head of the first metatarsalis, but most subjects misperceived the second large increase in pressure at the first toe and in muscle activity as the first large increase. Under the cooling condition, localized cooling did not affect the perceptibility of maximum pressure at the head of the first metatarsalis or the activity in the tibialis anterior, but the perceptibility of pressure at the first toe and activity of the abductor hallucis were reduced. There were individual differences in perceptibility of activity of the rectus femoris when the heel was cooled. Perceptibility of sequential changes in the pressure was affected differently by the localized cooling of each region. Given these findings, we discussed the role and interrelatedness of pressure sensation in perceiving large and sequential changes in somatosensory information while standing and leaning forward and backward.     

Postural movement pattern and muscle action sequence associated with self-paced bilateral arm flexion during standing

Investigated were postural movement pattern and action sequence of postural muscles while subjects rapidly flexed both arms during standing. The arm movement was started at the subject's own pace. Subjects were healthy individuals; 48 men and 53 women. Postural movement pattern was classified based on the movement angles of foot-leg (ankle joint) and leg-trunk (hip joint). Electromyograms were recorded from the anterior deltoid, biceps femoris, and erector spinae. The time difference between action onsets of the latter two muscles and the anterior deltoid was analyzed. Movement angles of the ankle and hip for both sexes were distributed on a similar linear regression line (y = -2.092x - 2.552 (r = -.71). The postural movement pattern was categorized based on the distribution into three types: hip flexion (in the 2nd quadrant), backward leaning (the 3rd), and hip extension (the 4th). The proportion of subjects was 26% in the hip flexion type, 55% in backward leaning type, and 19% in hip extension type. The action of biceps femoris and erector spinae significantly preceded that of anterior deltoid in the backward leaning and hip extension types but did not in the hip flexion type.     

The Church is Permanently Underway

This article examines the impact of the COVID-19 pandemic on the unity of the human community in Japan, specifically Tokyo, where the 2020 Olympic Games have been postponed until 2021. This allows reflection on the issue of ecclesiology during this time of uncertainty. First, the article describes the critical response of the ecumenical leaders to the country’s first-ever declaration of a state of emergency. Second, it reflects upon the impact of the compulsion to conform to intolerant social order and the neoliberal “self-responsibility theory” that abandons the most vulnerable in society. Third, it explores the relationship between Tokyo and the Olympics, which has been inextricably linked to the aim of national unity. Finally, this article draws the conclusion that we must steer clear of any “unity” that conceals a deeper disunity. Therefore, the church must distance itself from both the “self-responsibility theory” and the enthusiasm of nationalism and instead work toward the restoration of the human community and the renewal of the church, which are currently the main issues of concern.

Effects of anticipation certainty on preparatory brain activity and anticipatory postural adjustments associated with voluntary unilateral arm movement while standing

We examined the effects of anticipation certainty concerning which voluntary movement is required in response to a stimulus while standing on preparatory brain activity and anticipatory postural adjustments (APAs). Ten right-handed adults abducted their left or right arm rapidly in response to a visual imperative stimulus, based on the type of stimulus. A warning cue, which did or did not contain information about the side of arm abduction, was presented 2000ms before the imperative stimulus. Preparatory brain activity before arm abduction was quantified by the mean amplitude of the contingent negative variation 100ms before the imperative stimulus (late CNV amplitude). Compared with the low anticipation condition, in the high anticipation condition the following results were obtained only in the case of right arm abduction: (1) larger late CNV amplitude, (2) earlier postural muscle activities with respect to the focal muscle of arm abduction, and (3) smaller peak displacement of center of pressure during the abduction. These findings suggest that high anticipation of voluntary movement of dominant arm to a stimulus while standing influences preparatory brain activity before the movement, resulting in earlier APAs and thus smaller disturbance of postural equilibrium during the movement.     

How Religious Studies is Taught in Japan

This essay is part of a collection of short essays solicited from authors around the globe who teach religion courses at the college level (not for professional religious training). They are published together with an introduction in Teaching Theology and Religion 18:3 (July 2015). The authors were asked to provide a brief overview of the curriculum, student learning goals, and pedagogical techniques employed in their courses.     

The effects of video and nonnegative social feedback on distorted appraisals of bodily sensations and social anxiety

The effects of video feedback and nonnegative feedback from other people were examined as possibly ameliorating distorted appraisals of bodily sensations, as well as subjective and physiological anxiety in socially anxious individuals. Nonnegative feedback from a confederate emphasized the absence of negative outcomes (e.g., did not seem to tremble) rather than the presence of positive outcomes (e.g., looked calm). Socially anxious students were randomly assigned to either the experimental group, which received video and social feedback (n=12), or the control group (n 13). Participants were asked to give a videotaped speech twice. After the first speech, the experimental group watched the videotape of their speech and received feedback from a confederate, whereas the control group watched the video of another person's speech. The intervention improved distorted appraisal of bodily sensations and anticipatory anxiety for the experimental group. However, there were no differential effects on anxiety between the groups during speeches.
