A model of stage of change to recommend colonoscopy among urban primary care physicians.

Theory is little used in the prediction of physician cancer screening stage of change. Structural equation modeling was used to evaluate the theoretical predictors of stage of change to recommend colonoscopy among 235 urban physicians. Constructs from the theory of planned behavior, social-cognitive theory, and the transtheoretical model were systematically tested. As predicted, contextual factors, such as the physicians' ages, their race-ethnicities, patient race-ethnicity, and office-related barriers to preventive care were associated with stage of change through self-efficacy, normative beliefs, and negative behavioral beliefs. The findings demonstrate the relevance of these models to studying the behavior of physicians and support the development of interventions that are tailored to normative beliefs and specific physician cognitions for colonoscopy recommendation.     

Maternal views on aggression: Japan and Israel

Maternal views on aggressive behavior in their children were investigated in Japan and Israel. Sixty Japanese and 60 Israeli mothers of kindergarten children were interviewed individually about their children's fighting and quarreling. The findings indicate that both Japanese and Israeli mothers disapprove of their children's aggression on the basis of their value system, but their views of the same aggressive behavior differ considerably; Japanese mothers consider aggression among children as natural; aggression is a fact of life which has its constructive as well as destructive aspects, but it should be kept under control in order not to cause harm to others. Israeli mothers consider their children's aggression to be dangerous both for the child and for the relationship with the opponent. It is approved as a reaction to assault, mainly in self-defense and considered caused by emotions, tension, and lack of self-control. Thus, aggression is perceived by Japanese mothers as a natural and necessary aspect of development, while Israeli mothers perceive the same behaviors as justified mainly as reactions to assault or provocation and as expressing negative emotional states. © 1992 Wiley-Liss, Inc.     

Assessing Representations of Close Relationships Among Chinese and Japanese Adolescents and Young Adults: Commonalities and Differences in the Two Confucian Cultures

This article proposed an affective relationships model with its assessment instrument and examined how Chinese and Japanese adolescents and young adults construct mental representations of their close relationships, and the influence of Confucian cultural beliefs on these representations. The participants were 1,565 students aged 14 to 24 years living in China or Japan. The students were asked about their relationships with four figures: mother, father, closest friend, and romantic partner. We found that: (a) adolescents and young adults in both cultures constructed constellations of relationships containing multiple figures, and they articulated reasons for each figure's significance; and (b) there were between-group differences in the relationships with the father and the romantic partner for Chinese versus Japanese adolescents and young adults. These differences were partly explained by the influence of Confucianism on the Chinese participants’ cultural beliefs that retained the patriarchal values.     

The accuracy of abstracts in psychology journals

This article provides an empirically supported reminder of the importance of accuracy in scientific communication. The authors identify common types of inaccuracies in research abstracts and offer suggestions to improve abstract-article agreement. Abstracts accompanying 13% of a random sample of 400 research articles published in 8 American Psychological Association journals during 1997 and 1998 contained data or claims inconsistent with or missing from the body of the article. Error rates ranged from 8% to 18%, although between-journal differences were not significant. Many errors (63%) were unlikely to cause substantive misinterpretations. Unfortunately, 37% of errors found could be seriously misleading with respect to the data or claims presented in the associated article. Although deficient abstracts may be less common in psychology journals than in major medical journals (R. M. Pitkin, M. A. Branagan, & L. F. Burmeister, 1999), there is still cause for concern and need for improvement.     

Relationship between stages of smoking acquisition and environmental factors among junior high school students

To study the relationship of stages of smoking acquisition and environmental factors, 757 Japanese junior high school students (390 boys and 367 girls) anonymously answered a questionnaire regarding the four stages of smoking acquisition (precontemplation, contemplation, preparation, and action stages) and environmental factors of smoking behavior. Analysis showed that the influence of advertising and students' interpersonal situations on smoking behavior increased from the precontemplation stage to the action stage.     

Visual feature binding in early infancy

How does the developing brain of the human infant solve the feature-binding problem when visual stimuli consisting of multiple colored objects are presented? A habituation--dishabituation procedure revealed that 1-month-old infants have the ability to discriminate changes in the conjunction of a familiar shape and color in two objects. However, this good earlier performance was followed by poorer performance at 2 months of age. The performance improved again at 3 months of age. Detailed analysis of the oculomotor behaviors revealed that the age of 2 months was a period of drastic transition when the tendency to stay with the fixated objects disappeared and repetitive saccades between the two objects emerged. Our findings suggest that the ability to perceive conjunctions of features is available to infants very early, that the perceptual/neural basis at 1 and at 3 months of age may be fundamentally different, and that feature integration by vigorous eye movements or selective attention may be the key functional difference between the age groups.     

Distractor effect on the latent inhibition of conditioned flavor aversion in rats

Using a conditioned flavor aversion procedure with rats as subjects, the effect of the addition of a distractor stimulus on the magnitude of the latent inhibition effect was examined. Experiment 1 showed that latent inhibition to vinegar was attenuated by the addition of sucrose during preexposure. On the other hand, sucrose added during conditioning to vinegar did not attenuate latent inhibition. It was also found that the degree of latent inhibition to the vinegar-sucrose compound solution was less when vinegar alone was preexposed (i.e., when sucrose was added only during conditioning) than when the compound solution was preexposed (i.e., when sucrose was added both during preexposure and during conditioning). Experiment 2 gave similar results but with sucrose assigned as the target flavor and vinegar as the distractor. These findings are in full agreement with the generalization decrement account of latent inhibition.     

Genetic and environmental relationships between head circumference growth in the first year of life and sociocognitive development in the second year: a longitudinal twin study

Although growth in head circumference (HC) during infancy is known to predict later childhood outcomes, the mechanisms underlying this association with later sociocognitive abilities remain undetermined. Thus, using a sample of 241 pairs of normally developing Japanese twins, this study investigated the underpinnings of the association between HC growth (difference between HC at birth and at 10 months) and sociocognitive abilities at 19 months as measured by 10 items from the M-CHAT. Phenotypic correlations between HC at birth and sociocognitive abilities and between HC growth and sociocognitive abilities were marginal and not significant. However, multivariate genetic analyses using Cholesky decomposition revealed that genetic influences on HC growth and those on sociocognitive abilities were negatively associated. On the other hand, shared and nonshared environmental influences on HC growth were positively associated with influences on sociocognitive abilities. Genetic and environmental influences on HC at birth were not significantly associated with influences on sociocognitive abilities. These results help to clarify the role of brain growth during infancy in the subsequent development of sociocognitive abilities and highlight the importance of examining the different roles of genetic and environmental influences in studies of these areas.     

Smiling faces rated more feminine than serious faces in Japan

It has been reported that women and girls smile more frequently and more effectively than men and boys. It is expected that this correlation between femaleness and smiling affects the processing of faces, and consequently, smiling faces may be perceived to be more feminine. Participants viewed 30 photographs featuring smiling and serious facial expressions of both male and female subjects and rated them for femininity or masculinity. The result indicated that smiling faces significantly more frequently gave the impression of being more feminine. The interaction between the sex of the faces and their expression was not significant.     

Infant Mental Health Intervention for Preterm Infants in Japan: Promotions of Maternal Mental Health,Mother–Infant Interactions,and Social Support by Providing Continuous Home Visits until the Corrected Infant Age of 12 Months

The aim of this study was to investigate the effectiveness of the Japanese Infant Mental Health Program (JIMHP) for preterm mother–infant dyads until the infants reached 12 months of corrected age. Mothers in the JIMHP group (n = 26) received one hospital visit in addition to standard care in the Growing Care Unit (GCU) and five home visits based on the principles of infant mental health (IMH) after discharge from the hospital, until the infant reached 12 months of corrected age. In contrast, mothers in the control program group (n = 40) received standard care in the GCU and three conventional home visits during the same period. The dyads were then compared across groups, revealing that the JIMHP dyads showed less maternal depressive symptoms, better maternal interaction, increased social support by medical workers and healthcare professionals, a high persistence rate for attending the program, and a more positive perception toward the program (p < .05). However, there were no significant differences in the impact of parenting stress or in child development. These results are discussed in terms of their significance and the practical/clinical availability of IMH principles and the JIMHP as a new support model for preterm infants in Japan.
