The physical, emotional, and psychological changes that occur in adolescence prompt youths to have serious questions about their bodies, relationships, and health that are often personal, sensitive, or embarrassing. Past research has shown that adolescents are often reluctant to consult physicians, peers, and others for personal health questions due to concerns about confidentiality. One new venue for health information is the Internet, which is a promising resource due to its accessibility, interactivity, and anonymity. This study is a snapshot investigation of a popular health support website, which utilized a peer-generated bulletin board format to facilitate the discussion of adolescent health and social issues. Analyses of two health bulletin boards—one on teen issues and one on sexual health—were conducted on the questions and replies found on 273 topics of mainly anonymous adolescents collected over a 2-month period. Results revealed that the questions most frequently posted and viewed reflected interests and concerns about their changing physical, emotional, and social selves: Romantic relationships were the most frequent topic on the teen issues bulletin board; sexual health was the most frequent topic on the sexuality bulletin board. The bulletin boards proved to be a valuable forum of personal opinions, actionable suggestions, concrete information, and emotional support and allowed teens to candidly discuss sensitive topics, such as sexuality and interpersonal relations.  相似文献

How do the characteristics of sounds influence the allocation of visual–spatial attention? Natural sounds typically change in frequency. Here we demonstrate that the direction of frequency change guides visual–spatial attention more strongly than the average or ending frequency, and provide evidence suggesting that this cross-modal effect may be mediated by perceptual experience. We used a Go/No-Go color-matching task to avoid response compatibility confounds. Participants performed the task either with their heads upright or tilted by 90°, misaligning the head-centered and environmental axes. The first of two colored circles was presented at fixation and the second was presented in one of four surrounding positions in a cardinal or diagonal direction. Either an ascending or descending auditory-frequency sweep was presented coincident with the first circle. Participants were instructed to respond to the color match between the two circles and to ignore the uninformative sounds. Ascending frequency sweeps facilitated performance (response time and/or sensitivity) when the second circle was presented at the cardinal top position and descending sweeps facilitated performance when the second circle was presented at the cardinal bottom position; there were no effects of the average or ending frequency. The sweeps had no effects when circles were presented at diagonal locations, and head tilt entirely eliminated the effect. Thus, visual–spatial cueing by pitch change is narrowly tuned to vertical directions and dominates any effect of average or ending frequency. Because this cross-modal cueing is dependent on the alignment of head-centered and environmental axes, it may develop through associative learning during waking upright experience.  相似文献

Japanese women are often described as heavily invested in the role of mother, yet young women in contemporary Japan are increasingly likely to postpone or opt out of marriage and child rearing. To understand the psychological dynamics of parenting among Japanese women who have chosen to become mothers, we examined the relation of maternal role salience beliefs, personal maternal role commitment, and parenting self-efficacy to life satisfaction, number of children, and employment status. Survey data were obtained from 116 urban Japanese women with children in the 2nd grade. Mothers with more children expressed greater personal role commitment. Those who had sought employment were less likely to hold strong maternal role salience beliefs. Life satisfaction was predicted by having more children, feeling efficacious as a parent, and being employed. These findings suggest that even in a society characterized by strong normative expectations for women, women's life satisfaction and choices about family life and employment are related to individual beliefs, attitudes, and judgments about their role.  相似文献

The adult cerebral cortex can adapt to environmental change. Using monocular deprivation as a paradigm, we find that rapid experience-dependent plasticity exists even in the mature primary visual cortex. However, adult cortical plasticity differs from developmental plasticity in two important ways. First, the effect of adult, but not juvenile monocular deprivation is strongly suppressed by administration of barbiturate just prior to recording visual evoked potentials, suggesting that the effect of adult experience can be inactivated acutely. Second, the effect of deprivation is less persistent over time in adults than in juveniles. This correlates with the known decline in CREB function during maturation of the visual cortex. To compensate for this decline in CREB function, we expressed persistently active VP16-CREB and find that it causes adult plasticity to become persistent. These results suggest that in development and adulthood, the regulation of a trans-synaptic signaling pathway controls the adaptive potential of cortical circuits.  相似文献

This study demonstrates that children's difficulties in the interpretation of passives are attributed to their perspective-taking ability. Thirty-six Japanese preschool children participated in act-out sentence comprehension tasks. They were asked to manipulate two toy animals to demonstrate the meaning of two types of stimulus sentences: Type I had the child's toy, whose reference involved the child's actual name (e.g., Jun-kun no neko Jun's cat) encoded as grammatical subject, while Type II had the child's toy encoded as non-subject. Since passive structures take the perspective of the patient-denoting subject NP, it is assumed that only Type I passives have the perspective that matches that of the child.The results show that children's performance on passives was significantly better in Type I than in Type II sentences. But this difference was not observed for active sentences. For those who showed (nearly) perfect performance on active sentences, only Type I passives were equally well understood. These results strongly suggest that perspective-taking difficulties mask children's true competence on passives and that even 6-year-olds may not yet have attained the full perspective-taking ability required for comprehension of passive sentences.  相似文献

We investigated the association between alexithymic tendencies as measured by the 20-item Toronto Alexithymia Scale and the characteristics of aesthetic impressions for words and drawings. Impressions were measured using the semantic differential technique in three groups of Japanese students (High scores n = 31, Moderate scores n = 40, and a Control group n = 182) who were presented only words (Word condition), only drawings (Drawing condition), or pairs comprising one word plus one drawing that represented the same emotional categories (Drawing/Word condition). In a factor analysis on the data from participants, three factors (Evaluation, Activity, and Potency) were extracted. Based on the factor scores, the distances among the three conditions were calculated for each of the groups. For Potency, significant group differences were found between the Drawing/Word and other conditions. In the High-scoring alexithymia group, in particular, the Potency impressions based on tactile sensation, e.g., soft-hard, blunt-sharp, were amplified regardless of stimulus condition. These results are discussed in the context of somatosensory amplification associated with alexithymia and the difficulty of distinguishing between emotion and somatic sensations.  相似文献

Many studies have indicated that recognition of facial expression is geometrically represented in terms of two underlying bipolar dimensions, pleasure-displeasure and the intensity of arousal. A psychological space defined by these two dimensions has been found under particular conditions using prototype faces: however, the question arises whether this two-dimensional psychological space is also an accurate representation for faces with lower emotional intensity. To test this we prepared four different conditions of emotional intensity (100%, 75%, 50%, and 25% of emotionality) for six basic facial expressions using morphing. Participants (29 for the 100%, 30 for 75%, 35 for 50%, and 34 for the 25% condition) in each condition rated the facial stimuli on a 6-point scale of "not at all" and "very much so". Multidimensional scaling for each condition clearly indicated a two-dimensional representation and multiple correlations showed significant similarity across conditions (p < .001). This shows that the two-dimensional representation of recognition of facial expression is robust.  相似文献

Abstract : The present study investigated the function of satisfaction and frustration of the basic psychological needs – autonomy, competence, and relatedness – that contribute to subjective well‐being (life‐satisfaction, vitality, and depression) through a back‐translation procedure of the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS). A total of 564 Japanese undergraduates (356 males, 205 females, three unknown; M age = 18.61 years, SD = 1.48) participated in a questionnaire survey. Confirmatory factor analysis showed that the BPNSFS had the same six‐factor structure as that found in the original version. Structural equation modeling showed that satisfaction of each of the three needs contributed to the prediction of subjective well‐being (life satisfaction and vitality), whereas frustration of each need uniquely contributed to the prediction of ill‐being (depressed affect). These results support previous findings found in Belgium, China, the USA, and Peru, confirming that satisfaction of basic psychological needs represents a critical element for healthy functioning across cultures. However, controlling for the effects of the Big Five personality traits indicates the possible over‐estimation for the functions of the needs while clarifying these roles.  相似文献

Various models have been proposed to increase understanding of the cognitive basis of facial emotions. Despite those efforts, interactions between facial emotions have received minimal attention. If collective behaviours relating to each facial emotion in the comprehensive cognitive system could be assumed, specific facial emotion relationship patterns might emerge. In this study, we demonstrate that the frameworks of complex networks can effectively capture those patterns. We generate 81 facial emotion images (6 prototypes and 75 morphs) and then ask participants to rate degrees of similarity in 3240 facial emotion pairs in a paired comparison task. A facial emotion network constructed on the basis of similarity clearly forms a small-world network, which features an extremely short average network distance and close connectivity. Further, even if two facial emotions have opposing valences, they are connected within only two steps. In addition, we show that intermediary morphs are crucial for maintaining full network integration, whereas prototypes are not at all important. These results suggest the existence of collective behaviours in the cognitive systems of facial emotions and also describe why people can efficiently recognize facial emotions in terms of information transmission and propagation. For comparison, we construct three simulated networks—one based on the categorical model, one based on the dimensional model, and one random network. The results reveal that small-world connectivity in facial emotion networks is apparently different from those networks, suggesting that a small-world network is the most suitable model for capturing the cognitive basis of facial emotions.  相似文献
