Well-Being and Generalized Anxiety in Japanese Undergraduates: A Prospective Cohort Study

Psychological well-being is thought to protect against common mental health problems. This study investigated the buffering effects of psychological well-being on the relationships between cognitive vulnerabilities (fear of anxiety and negative beliefs about worry) and GAD symptoms among 297 Japanese undergraduates (female = 62%, age = 18.91 ± 1.61) in a two-wave prospective cohort study. Participants completed the Generalized Anxiety Disorder Questionnaire for DSM-IV, Center for Epidemiologic Studies Depression Scale, anxiety control subscale of Affective Control Scale, negative belief about worry subscale of Meta-Cognitions Questionnaire, and Nishida’s psychological well-being scale. A moderated regression analysis tested the buffering effect of psychological well-being sub-dimensions on the relationship between cognitive vulnerabilities and generalized anxiety symptoms. Fear of anxiety (β = 0.16, p < 0.01) and negative beliefs about worry (β = 0.16, p < 0.01) at baseline predicted generalized anxiety at follow-up, after controlling for baseline symptoms, and three interaction terms significantly predicted generalized anxiety symptoms. Purpose in life and autonomy buffered the negative relationship between cognitive vulnerabilities and generalized anxiety symptoms. Contrary to the hypothesized relationship, positive relationships with others at baseline facilitated a positive relationship between fear of anxiety and generalized anxiety symptoms. Those results suggested that enhanced Purpose in life and Autonomy dimension of Psychological well-being may be useful in preventing GAD, while the enhanced positive relationship with others dimension of Psychological well-being may facilitate generalized anxiety, as a function of fear of anxiety. In a primary prevention setting, it may be useful to consider the dimensions of Psychological well-being.     

Patients' desire to participate in decision-making in psychiatry: a questionnaire survey in Japan

Japanese national sentiment has been described as paternalistic, which has potentially wide-ranging implications for the manner in which psychiatric patients should participate in medical decision-making. To examine the extent and possible determinants of the desire to participate in medical decision-making among Japanese people, we distributed a packet of questionnaires to 747 (nonmedical) university students and 114 of their parents. The questionnaires included an imaginary case vignette of psychotic depression. The participants were asked whether they would want various types of medical information, i.e., diagnosis, aetiology, treatment, outcomes, medical charts, etc., disclosed to them were they in such a psychiatric condition. Also included was the 1995 Scale for Independent and Interdependent Construal of the Self by Kiuchi. More than half of the participants wanted all the types of medical information disclosed to them. Those participants who wanted to have all types of information disclosed to them (n = 413) as compared to those who did not want to know at least one type of information (n = 445), tended to be male and to have an educational background in psychiatry (9.7% vs 5.4%) as well as an assertive attitude as indicated by a higher score on Independence on the Scale for Independence and Interdependent Construal of the Self. These results suggest that the Japanese in this sample are more likely to want to make an autonomous contribution to the psychiatric decision-making process and that less desire for information can be predicted by some demographic and personality factors.     

Attention-Affect Check List: A self-report measure of acute mental stress

Given a hint from Lang, Bradley, and Cutbert's (1997) defense cascade, two cognitive processes, instead of passive versus active behavioral coping, which seem to have differential effects on the provocation of vascular- versus cardiac-dominant reaction pattern during mental stress were advocated: attention (Attent) versus unpleasant affect (UnplAff). Based on this notion the Attention-Affect Check List (AACL) was developed as a self-report measure. In addition, items on uncontrollability (Uncontr) were prepared for the purpose of checking whether heightened Attent and UnplAff are accompanied by alterations in Uncontr. Two hundred and eighty-four students underwent two kinds of mental stress, which seemed to specifically heighten Attent and UnplAff. Four factors with four items each were extracted from the AACL item pool: concentrated and allocated Attent, UnplAff, and pleasant affect. Also, one factor with four items was extracted from the Uncontr item pool. For both the mental stresses, each scale, although very brief, had quite reasonable alpha reliability. Accountability of each scale for the total variance was reasonably high. Some problems are discussed in relation to the validity of AACL.     

The adaptation process of mothers to the birth of children with Down Syndrome and its psychotherapeutic assistance: A retrospective approach

The findings of Niwa/Tanaka's studies on mothers' adaptation process to Down Syndrome infants through prospective and long-term intervention were reeaxmined through mothers' retrospective accounts of their past experiences. Fifteen mothers volunteered to participate in clinical interviews prepared for this purpose. The following results were obtained from the interviews: (1) The adaptation of mothers of Down Syndrome children involved a process enduring far beyond the initial shock, so that long-term longitudinal support and intervention, both developmental and psychotherapeutic, were necessary; (2) The subjects experienced intense psychological shock twice before their children reached school age, as we had predicted through our clinical experiences. An adaptation process consisting of five stages was observed; (3) Although the maternal affects experienced by the Japanese mothers in their process of adaptation generally looked similar to those of American and British mothers, some affective reactions were discovered that seemed to reflect existing Japanese social conditions and cultural peculiarities by which these mothers were deeply influenced; (4) A tentative model for intervention to support mothers' adaptatipn process is proposed based on the findings of the present study.     

Achievement motives,cognitive and social competence,and achievement goals in the classroom

This study investigated the interrelations of approach and avoidance achievement motives (Motive to Achieve Success and Motive to Avoid Failure), two types of competence (Cognitive and Social competence), achievement goals (Mastery, Performance-approach, Performance-avoidance, and Work Avoidance goals), of 131 eighth and ninth grade students from a Japanese junior high school. Multiple regression analysis indicated positive relations between Mastery goals and the Motive to Achieve Success and Cognitive Competence. Performance-approach goals and both the Motive to Achieve Success and the Motive to Avoid Failure, and Performance-avoidance Goals and both the Motive to Achieve Success and the Motive to Avoid Failure. Negative relations were found between Work Avoidance goals and the Motive to Achieve Success and Cognitive Competence. Several interactions between achievement motives and competence on achievement goals were also found. The different antecedents of four achievement goals were discussed.     

A neural basis for expert object recognition

Although most adults are considered to be experts in the identification of faces, fewer people specialize in the recognition of other objects, such as birds and dogs. In this research, the neurophysiological processes associated with expert bird and dog recognition were investigated using event-related potentials. An enhanced early negative component (N170, 164 ms) was found when bird and dog experts categorized objects in their domain of expertise relative to when they categorized objects outside their domain of expertise. This finding indicates that objects from well-learned categories are neurologically differentiated from objects from lesser-known categories at a relatively early stage of visual processing.     

The assumed effects of positive feedback paired with success on motivation to do a task: The cases of characters with high and low initial levels of interest

This study investigated the effects of positive feedback paired with success on motivation to do a task, and examined whether this differed according to whether the person performing the task had a high or low initial level of interest in that task. Subjects (448 junior college students) were asked to rate (from 0–10) the level of motivation of characters in four different stories. Subjects believed that positive feedback would encourage the character to do a task regardless of initial level of interest. However, when positive feedback could not be expected, ratings for motivation fell. Ratings for motivation were further analyzed when no positive feedback could be expected, either after an earlier experience of positive feedback paired with success or after success only (no feedback). In the case of a low initial level of interest, it was assumed that motivation would be increased after positive feedback, but in the case of a high initial level of interest motivation was assumed to be decreased by an earlier experience of positive feedback paired with success. These results suggest that the effect of positive feedback paired with success will differ according to the level of a person's initial interest.     

Typicality effects in face and object perception: further evidence for the attractor field model

In a previous study, it was shown that a 50/50 morph of a typical and an atypical parent face was perceived to be more similar to the atypical parent face than to the typical parent face (Tanaka, Giles, Kremen, & Simon, 1998). Experiments 1 and 2 examine face typicality effects in a same/different discrimination task in which typical or atypical faces and their 80%, 70%, 60%, and 50% morphs were presented sequentially (Experiment 1) or simultaneously (Experiment 2). The main finding was that in both modes of presentation, atypical morphs were more poorly discriminated than their corresponding typical morphs. In Experiment 3, typicality effects were extended to the perception of nonface objects; in this instance, it was found that 50/50 morphs of birds and cars were judged to be more similar to their atypical parents than to their typical parents. These results are consistent with an attractor field model, in which it is proposed that the perception of a face or object stimulus depends not only on its fit to an underlying representation, but also on the representation's location in the similarity space.     

Recognition of pictorial representations by chimpanzees (<Emphasis Type="Italic">Pan troglodytes</Emphasis>)

In this study, I investigated chimpanzees' ability to recognize pictorial representations. Four adults and three juvenile chimpanzees were trained to choose images of photographs of flowers among 12 items belonging to four categories on a touch-sensitive monitor. As a generalization test, the following five types of images were presented: (1) novel photographs, (2) colored sketches (more realistic), (3) a colored clip art (cartoon-like images), (4) black-and-white line drawings, and (5) Kanji characters (as the control images). One adult and all three juvenile chimpanzees were able to choose any style of the nonphotographic images of flowers significantly above the chance level, whereas none could choose the correct Kanji characters corresponding to a flower significantly above the chance level. The other three adult chimpanzees' performance level did not exceed the chance level in terms of choosing nonphotographic images although they showed good transfer skills to novel photographs. The results revealed that not all chimpanzees could recognize pictures used by humans without training. The results also suggest "critical period" in acquisition of skill in recognizing pictures in chimpanzees. Only one adult chimpanzee, who had acquired skill in recognizing visual symbols, also recognized pictures aside from the juvenile chimpanzees. Her learning history might have aided her in acquiring this skill. The results of this study suggest a relationship between pictorial competence and symbolic one.
