Does high educational level protect against intellectual decline in older adults?: A 10‐year longitudinal study

This study examined the relation between educational level and intellectual change in Japanese older adults. Participants (age = 65–79 years, n = 593) comprised the first‐wave participants of the National Institute for Longevity Sciences‐Longitudinal Study of Aging (NILS‐LSA). They were followed for 10 years and were tested six times. Educational levels were divided into two groups (low‐educated or high‐educated), and intellectual changes for the 10 years were assessed using the Japanese Wechsler Adult Intelligence Scale‐Revised Short Forms (JWAIS‐R‐SF); subtests included Information, Similarities, Picture Completion, and Digit Symbol. General linear mixed‐model analyses revealed that education had not affected 10‐year changes of the Information, Similarities, and Picture Completion subtest scores. In contrast, education was significantly associated with a change in the Digit Symbol subtest score; individuals with higher levels of education showed greater decline than those with less education, although they had higher ability at every time point. These findings suggest that higher education does not protect against intellectual decline in late life, although it is associated with long‐term individual differences in intelligence.     

Eye movement during facial affect recognition by patients with schizophrenia, using Japanese pictures of facial affect

A possible relationship between recognition of facial affect and aberrant eye movement was examined in patients with schizophrenia. A Japanese version of standard pictures of facial affect was prepared. These pictures of basic emotions (surprise, anger, happiness, disgust, fear, sadness) were shown to 19 schizophrenic patients and 20 healthy controls who identified emotions while their eye movements were measured. The proportion of correct identifications of 'disgust' was significantly lower for schizophrenic patients, their eye fixation time was significantly longer for all pictures of facial affect, and their eye movement speed was slower for some facial affects (surprise, fear, and sadness). One index, eye fixation time for "happiness," showed a significant difference between the high- and low-dosage antipsychotic drug groups. Some expected facial affect recognition disorder was seen in schizophrenic patients responding to the Japanese version of affect pictures, but there was no correlation between facial affect recognition disorder and aberrant eye movement.     

Depression in the early postpartum period and attachment to children—in mothers of NICU infants

Depression in early puerperium was evaluated in terms of maternal attachment in mothers of children admitted to the neonatal intensive care unit (NICU) in comparison to a control group of mothers of full‐term infants. A survey including Zung's self‐rating depression scale (ZSDS), a postpartum maternal attachment scale and items addressing the mother's feelings and peripheral conditions was conducted on mothers of children admitted to the NICU. Among the 153 mothers who gave valid responses, positive ZSDS scores of over 40 were seen in 61.8%. In terms of the children's disorder, strong depressive tendency was noted among mothers of low birth weight infants. Significant correlation was noted between the ZSDS and the ‘core maternal attachment’ (negative correlation) and ‘anxiety regarding children’ (positive correlation) subscales of postpartum maternal attachment. Path analysis revealed the father's positive reaction in learning of the pregnancy resulted in elevation of the ‘core maternal attachment’ score, in contrast to the control group mothers.

Prevalence of maladaptive behavior in retarded children as a function of IQ and age

One hundred and twentyeight mentally retarded children, ages 6 to 14, from a special school were assessed by teachers in terms of nine maladaptive behaviors. The results indicated that the prevalence of some maladaptive behaviors changed as a function of IQ and age, and that there were splits of such changes as IQ-dependent and as age-dependent by maladaptive behavior.     

Reorganised anticipatory postural adjustments due to experimental lower extremity muscle pain

Automated movements adjusting postural control may be hampered during musculoskeletal pain leaving a risk of incomplete control of balance. This study investigated the effect of experimental muscle pain on anticipatory postural adjustments by reaction task movements. While standing, nine healthy males performed two reaction time tasks (shoulder flexion of dominant side and bilateral heel lift) before, during and after experimental muscle pain. On two different days experimental pain was induced in the m. vastus medialis (VM) or the m. tibialis anterior (TA) of the dominant side by injections of hypertonic saline (1 ml, 5.8%). Isotonic saline (1 ml, 0.9%) was used as control injection. Electromyography (EMG) was recorded from 13 muscles. EMG onset, EMG amplitude, and kinematic parameters (shoulder and ankle joint) were extracted. During shoulder flexion and VM pain the onset of the ipsilateral biceps femoris was significantly faster than baseline and post injection sessions. During heels lift in the VM and TA pain conditions the onset of the contralateral TA was significantly faster than baseline and post injection sessions in bilateral side. VM pain significantly reduced m. quadriceps femoris activity and TA pain significantly reduced ipsilateral VM activity and TA activity during bilateral heel lift. The EMG reaction time was delayed in bilateral soleus muscles during heels lift with VM and TA pain. The faster onset of postural muscle activity during anticipatory postural adjustments may suggest a compensatory function to maintain postural control whereas the reduced postural muscle activity during APAs may indicate a pain adaptation strategy to avoid secondary damage.     

The genetic structure of Cloninger's seven-factor model of temperament and character in a Japanese sample

Theoretical assumptions regarding the genetic and environmental structure of personality proposed in Cloninger's seven-factor model of temperament and character were verified in a Japanese sample by using the twin method. The Temperament and Character Inventory (TCI) was administered to 296 twin pairs ranging in age from 14 to 28 years old. Among four temperament dimensions (novelty seeking [NS], harm avoidance [HA], reward dependence [RD], and persistence [PS]), HA and PS showed significant additive genetic contributions and no shared environmental effect, supporting the original theoretical assumption. NS and RD could be explained by either genetic or shared environmental factors with nonshared environment. All three character dimensions (cooperativeness [CO], self-directedness [SD], and self-transcendence [ST]) could be explained exclusively by additive contributions and no shared environmental effect. Multivariate genetic analysis indicated that there were no significant associations between NS, HA, and RD, as the theory predicts, and the genetic components of PS, SD, and CO were derived from those of the temperament dimensions. The fourth genetic component, which had a substantial load specifically on ST and overlapped with PS, was identified. Although most of the nonshared environmental effects were trait-specific, the phenotypic correlation between NS and HA could be explained by nonshared environmental overlap.     

Characteristics of Telephone Crisis Hotline Callers with Suicidal Ideation in Japan

Hotline callers do not always have suicidal ideation and previous studies have noted that the rate of such callers is limited. Crisis hotline counselors must be able to identify high‐risk callers in order to provide appropriate support. This study investigated the characteristics of Japanese crisis hotline callers in 2012 (N = 541,694) and is the first to analyze crisis hotline data for all parts of Japan over 1 year. About 14% of the callers had suicidal ideation and 6% had a history of attempted suicide. The odds ratio for suicidal ideation among those with a history of attempted suicide was 15.5. The suicidal ideation rate was much smaller compared to previous studies in other countries. There is a psychological barrier that must be broken for high‐risk people to use support hotlines. In addition, attempted suicide is a strong exclusive predisposing factor for death due to suicide; therefore, counselors should pay careful attention to callers with a history of attempted suicide. The characteristics of Japanese crisis hotline callers and the features of suicidal ideation revealed in the present study are expected to be useful in developing telephone crisis hotline strategies.     

Community Psychology in Japan: A Historical Review

Dans cette rétrospective historique, nous retraçons le développement de la communauté psychologique japonaise des années 1960 aux années 1980 en distinguant trois périodes: la période de démarrage (fin décennie 60), la période allant de la naissance aux premiers balbutiements (décennie 70) et la période du développement et de l'indépendance (décennie 80). De plus, nous précisons le statut actuel de la communauté psychologique japonaise et présentons une brève discussion sur les problémes à règler dans le futur.
In this historical review, we trace the development of Japan's community psychology from the 1960s to the 1980s by dividing it into three periods: the quickening period (late 1960s), a period from birth to toddling age (1970s) and a period of development and independence (1980s). In addition, we outline the present status of Japan's community psychology and present a brief discussion on some problems to be addressed in the future.     

Relationships among mental health,coping styles,and mood

The present study investigated the relationships between mental health (measured by the General Health Questionnaire--6 factors: General Illness, Somatic Symptoms, Sleep Disturbance, Social Dysfunction, Anxiety and Dysphoria, Suicidal Depression), coping styles (two strategies: Cognitive centered, Emotional centered), and mood (Tense Arousal, Energetic Arousal). 96 students answered questionnaires before their semester test which was a stressor. Analysis showed that (1) Tense Arousal scores correlated positively with overall General Health scores and all General Health factor scores, and Energetic Arousal scores correlated negatively with overall General Health scores and all General Health factor scores except one; (2) Anxiety and Dysphoria scores predicted Tense Arousal scores the best of General Health factor scores, while both Social Dysfunction scores and General Illness scores predicted Energetic Arousal scores. (3) Participants with high Energetic Arousal scores used a Cognitive centered coping strategy much more than an Emotional centered coping strategy. That is, people with low Energetic Arousal scores seem to use the Emotional centered coping strategy and have anxiety/dysphoria, while people with high Energetic Arousal scores seem to use a Cognitive centered coping strategy and have good health and social activity. These results suggest that there are small but significant relationships among mental health, coping styles, and mood.
