Research on attachment predominantly traces the effect of a single or primary attachment and/or attachment style on working models and behavior. However, most children form multiple attachments. This article reviews research on multiple attachment representations in children and considers how such information can usefully be applied to clinical settings. Through the case study of a six-year-old adopted boy with a history of maltreatment, it explores how those internal working models can be assessed in treatment and the clinical value of recognizing different attachment representations and styles. Implications for treatment interventions are explored.  相似文献

When two targets are presented using rapid serial visual presentation (RSVP) and the interval between the targets is 200–500 ms, detection or identification of the second target is impaired. This impairment in second target report is known as the attentional blink (AB). This study sought to examine the impact of the direction of target association on priming during an AB task using very short and long SOAs. Two experiments were conducted using dual-stream RSVP tasks and targets that either shared an associative relationship or were unrelated to one another. The direction of association between the targets was also varied so that associatively related targets were presented in the forward (strongest association from target 1 to target 2) or backward directions of association (strongest association from target 2 to target 1). In Experiment 1 very short SOAs between targets (27–213 ms) were used. Priming was evident at the same SOAs for both targets presented in the backward direction of association. However, for targets presented in the forward direction of association, priming occurred for target 1 and target 2 at different SOAs. Experiment 2 used longer SOAs between targets (107 to 535 ms) and it was determined that while direction of association between the targets did not affect priming, there was a larger priming effect for target 2 than for target 1. The results of the two experiments indicate that direction of association between targets influences priming in RSVP tasks that use very short but not long SOAs. The results are discussed in relation to the two-stage response competition model of Potter et al. (J Exp Psychol Hum Percept Perform 28:1149–1162, 2002).  相似文献

This research examines the moderating effect of conflict avoidance on the relationship between conflict and psychological adjustment among 45 expatriate couples at two points in time. We propose a model based on the actor–partner interdependence model, which assumes both intrapersonal and interpersonal effects, to address simultaneously the effects of one's own and the other's avoidance behavior. We found substantial support for our model, especially for expatriate spouses. As expected, and only for expatriate spouses, avoidance moderated the conflict–adjustment relationship such that both one's own and one's counterpart's avoidance behavior diminished the negative effect of conflicts. Because these effects were observed only at T2 and psychological adjustment decreased from T1 to T2, our research suggests that the impact of expatriation-associated interaction particularly manifests itself in the long run.  相似文献

ABSTRACT

This study investigated the effects of using digital augmentation to enhance an exhibit device to influence conceptual understanding about a science topic in a science museum setting. In particular, the study considered how students in Grades 6–8 engaged with the device that was available in both augmented and nonaugmented (control) conditions. Results show increased cognitive (critical thinking) skills when the digital augmentation was present that we hypothesize led to increased conceptual gains. We illustrate how this research contributes to three important areas of need identified in informal science literature: the need for evidence of conceptual and cognitive gains; the need for understanding how digital platforms improve the learning experience; and the need to demonstrate how designed interactive devices may impact higher order skills such as critical thinking and theorizing.  相似文献

ABSTRACT

Visitor experiences and interpretation at wildlife tourism sites are often designed to encourage visitors to adopt conservation actions. Typically, conservation messages are delivered via one-size-fits-all interpretive signage, with little consideration given to whether the same information attracts and engages different cultural groups. This study explores Chinese and international visitors’ perceptions of signage at the Chengdu Research Base of Giant Panda Breeding in China. Four sign prototypes were designed and a combination of visitor observations, interviews, and exit surveys were used to test their attracting and holding power. Comparisons of Chinese and Western visitors revealed no significant difference in the proportion who stopped to read signs. Preferences for signage elements were also similar across the two cultural groups; however, there were differences in terms of what visitors thought should be included in wildlife interpretation. Implications for the design and delivery of interpretation in Chinese wildlife tourism settings are discussed.  相似文献

Adolescent dating violence (ADV) remains a significant concern, particularly among rural African Americans. Few studies have explored adolescents’ perceptions about the link between ADV and sexual health and none have targeted this population. Employing qualitative methods based in Community-Based Participatory Research and theory, this study explored rural African American adolescents’ knowledge, perceptions and beliefs about the impact of ADV on sexual health. Secondary data analysis of 20 semi-structured individual interviews, conducted with older adolescents (aged 18–21), revealed participants understood the link between ADV and sexual health consequences, specifically as it related to STI and HIV prevention, condom use, and refusal of sex; and the negative impact refusing sex, communicating about HIV and other STI prevention, and negotiating condom use can have on ADV. This included: (a) negative relationship outcomes, including ADV and fear; and (b) factors that impact one’s ability to refuse sex, communicate about HIV and STI prevention, and negotiate condom use. Findings underscore the need for comprehensive ADV prevention programs for rural African Americans.  相似文献

ABSTRACT

Self-reflection is critical for visitors to make sense of an exhibit collection in which they are the subject of investigation and may play an important role in any informal learning context. This study examines this construct by listening for self-reflective talk at Mind, an exhibit collection focused on helping visitors explore aspects of themselves rather than external objects or phenomena. It addresses 3 questions: (a) What does self-reflective talk sound like in such a collection? (b) What categories of self-reflective talk are prevalent? (c) What types of exhibits engender what categories of self-reflective talk? Findings indicate that self-reflective talk comes in various forms. Self-monitoring talk, including self-assessments about how visitors are feeling and doing and what they know, is more prevalent than self-connecting talk, comments about visitors’ own lives, values, and their sense of self. Comparisons among different types of exhibits suggest that exhibits designed for multiple users prompt high frequencies of self-connecting talk and self-monitoring talk, whereas interactive exhibits and exhibits that pose a challenge elicit high frequencies of self-monitoring but not self-connecting talk. Additional work is needed to better understand self-reflection, its role in informal learning, and effective means of fostering self-reflection in science museums.  相似文献

One barrier to widespread public access to empirically supported treatments (ESTs) is the limited availability and high cost of professionals trained to deliver them. Our earlier work from 2 clinical trials demonstrated that front-line addiction counselors could be trained to deliver a manualized, group-based cognitive behavioral therapy (GCBT) for depression, a prototypic example of an EST, with a high level of adherence and competence. This follow-up article provides specific recommendations for the selection and initial training of counselors, and for the structure and process of their ongoing clinical supervision. We highlight unique challenges in working with counselors unaccustomed to traditional clinical supervision. The recommendations are based on comprehensive feedback derived from clinician notes taken throughout the clinical trials, a focus group with counselors conducted 1 year following implementation, and interviews with key organization executives and administrators.  相似文献

Four experiments are reported that investigate the usefulness of rigid (head nodding, shaking) and nonrigid (talking, expressions) motion for establishing new face representations of previously unfamiliar faces. Results show that viewing a face in motion leads to more accurate face learning, compared with viewing a single static image (Experiment 1). The advantage for viewing the face moving rigidly seems to be due to the different angles of view contained in these sequences (Experiment 2). However, the advantage for nonrigid motion is not simply due to multiple images (Experiment 3) and is not specifically linked to forwards motion but extends to reversed sequences (Experiment 4). Thus, although we have demonstrated beneficial effects of motion for face learning, they do not seem to be due to the specific dynamic properties of the sequences shown. Instead, the advantage for nonrigid motion may reflect increased attention to faces moving in a socially important manner.  相似文献

ABSTRACT

Reproductive loss—the loss of a pregnancy before 24 weeks—is estimated to occur in 20-50% of all pregnancies. It is a common human experience. However, it is an experience that is shrouded in silence and mystery. Not only is reproductive loss culturally taboo but given the marked absence of theological reflection on the experience, it would seem to be theologically taboo as well. The experience of reproductive loss raises profound theological questions about what it means to be (a gendered) human, issues of suffering, the providence of God, and eschatology. This research considers some of the reasons for this theological silence and begins to examine the experience of reproductive loss with the aim of taking the embodied experience of the miscarrying woman seriously as a site for theological reflection.  相似文献
