Hyperactivity/inattention problems moderate environmental but not genetic mediation between negative parenting and conduct problems

This study investigated the association between negative parenting (NP) and conduct problems (CP) in 6-year-old twins, taking into account the severity of hyperactivity/inattention problems (HIAP). Analyses of the data from 1,677 pairs of twins and their parents revealed that the shared environmental covariance between NP and CP was moderated by the level of HIAP but not by CP or NP, where the shared environmental covariance was larger in children with higher levels of HIAP than in children with lower levels of HIAP. The genetic covariance between NP and CP was not moderated by the level of HIAP, whereas it was larger in the group with lower levels of CP and NP than in the group with higher levels. These results suggest that severe HIAP strengthens shared environmental associations between NP and CP and that interventions focusing on the shared environmental component of NP would be effective for parents and children with severe HIAP.     

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.     

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.     

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.     

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.     

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.
