This paper describes how the multi-energy sensor array has been refitted to meet the needs of measuring geomagnetic and other types of electromagnetic phenomena in an environment. This portable laptop computer system was designed to measure the interaction of multiple frequencies with the psychological and physiological processes that underlie human exposure to electromagnetic fields across the spectra. New sensors and analytical software have been implemented in the new configuration. 相似文献

The purpose of this study was to examine the extent to which anxiety-related individual difference variables predict anxious responding when individuals experience aversive bodily sensations. Thus, we explore several psychological and behavioral predictors of response to a single 25-sec inhalation of 20% carbon dioxide-enriched air in 70 nonclinical participants. Predictor variables included anxiety sensitivity, suffocation fear, heart-focused anxiety, and breath-holding duration. Multiple regression analyses indicated that only anxiety sensitivity significantly predicted postchallenge panic symptoms, whereas both anxiety sensitivity and suffocation fear predicted postchallenge anxiety. These data are in accord with current models of panic disorder that emphasize the role of fear of fear in producing heightened anxiety and panic symptoms and help clarify specific predictors of anxiety-related responding to biological challenge. 相似文献

A Systematic Review: Non‐Suicidal Self‐injury in Australia and New Zealand's Indigenous Populations 下载免费PDF全文
Objective
To undertake a systematic review of non‐suicidal self‐injury (NSSI) prevalence, patterns, functions, and behavioural correlates for the Indigenous populations of Australia (Aboriginal and Torres Strait Islanders) and New Zealand (NZ; Maori).Method
We searched the following electronic databases: PubMed, MedLine, Scopus, Web of Science, ScienceDirect, PsycInfo, and PsycArticles, CINAHL, and the Informit Health and Indigenous Peoples collections. Studies were included for review if they were published within the last 25 years and reported on NSSI in Australia and NZ's Indigenous populations.Results
Seven studies were included, six of which came from Australia. The prevalence of NSSI in Australia ranged from 0.9% up to 22.50%; statistics varied by the different samples, types of prevalence, and relationship to alcohol. Several studies found that Aboriginal and Torres Strait Islander peoples had higher rates of NSSI than other Australians, but that this was not significantly higher. Two studies indicated that NSSI was linked to alcohol use, incarceration, and a younger age. The one NZ study was of injury and not specifically NSSI.Conclusions
Findings are limited due to a small pool of literature. Cultural variations in NSSI presentation should be considered when working with Indigenous populations. Further research is required to help determine what cultural variations may exist. 相似文献54.
This study used interpretative phenomenological analysis (IPA) to explore the lived experiences of five individuals diagnosed with obsessive-compulsive disorder (OCD) who underwent a group cognitive behavioral therapy (CBT) intervention program to address their symptoms. Two master themes were identified: experiences and processes of change and reflections on change. For all participants, the degree of group cohesion or connectedness they established with group members emerged as highly important in facilitating therapeutic progress. A number of technical elements of cognitive behavioral therapy (CBT) were also notable therapeutic factors, including questioning/rationalizing maladaptive interpretations about intrusions. However, the commonality of non-specific group processes as key features for subsequent therapeutic change prompts the need for further research in dynamics within CBT group interventions for OCD. 相似文献

LEGO® construction sets are a staple in many children’s lives. Given worldwide distribution, generations of children have grown up playing with these brightly colored, interlocking plastic bricks. Historically marketed to all children, the LEGO® Group has begun targeting male and female consumers differentially with the introduction of product lines such as LEGO® City and LEGO® Friends. Although the packaging, marketing, brick colors, and characters have changed, little is known about whether these product series encourage differences in the way boys and girls play. This content analysis compared the play narratives of sets marketed to boys (LEGO® City) and girls (LEGO® Friends). Our analysis found distinct gendered messages that encourage boys to enact various skilled professions, heroism, and expertise, whereas girls are encouraged to focus on having hobbies, being domestic, caring for others, socializing, being amateurs, and appreciating and striving for beauty. Although LEGO® City and Friends sets offer opportunities for construction, they also promote stereotyped gender roles for enacting femininity and masculinity in play. Parents, educators, and practitioners often focus on the educational affordances of LEGO® construction. We recommend that they also consider the other lessons, both explicit and implicit, being taught through gender-specific LEGO® sets. 相似文献

Research points to the positive impact that gender-segregated schooling and classroom initiatives exert on academic attainment. An evaluation of these studies which reveal positive effects highlights, however, that students are typically selectively assigned to single- or mixed-gender instructional settings, presenting a methodological confound. The current study controls for students’ prior attainment to appraise the efficacy of a single-gender classroom initiative implemented in a co-educational high school in the United Kingdom. Secondary data analysis (using archived data) was performed on 266 middle-ability, 11–12 year-old students’ standardized test scores in Languages (English, foreign language), STEM-related (Mathematics, Science, Information and Communication Technology), and Non-STEM subjects (art, music, drama). Ninety-eight students (54, 55% female) were taught in single-gender and 168 (69, 41% female) in mixed-gender classrooms. Students undertook identical tests irrespective of classroom type, which were graded in accordance with U.K national curriculum guidelines. Controlling for students’ prior attainment, findings indicate that students do not appear to benefit from being taught in single-gender relative to mixed-gender classrooms in Language and STEM-related subjects. Young women benefitted from being taught in mixed-gender relative to single-gender classes for Non-STEM subjects. However, when prior ability is not controlled for, the intervention appears to be effective for all school subjects, highlighting the confounding influence of selective admissions. These findings suggest that gender-segregated classroom initiatives may not bolster students’ grades. It is argued that studies that do not control for selection effects may tell us little about the effectiveness of such interventions on scholastic achievement. 相似文献

Must readers intend to process a word to activate various levels of representation, or is such processing simply triggered by the presentation of a word (i.e., is it “automatic”)? This issue was addressed via the use of Besner and Care’s Task Set paradigm. On each trial a cue, which indicated which of two tasks to perform appeared either before the target, or at the same time as the target. If subjects can process the target while preparing a task set, then the effect of a manipulated psycholinguistic factor should be absorbed into the time taken to process the cue. Despite robust main effects of SOA and word frequency there was no interaction between these factors when the task was to read aloud. This result implies that target processing is delayed until the subject knows what task to perform, and therefore that intention plays an important role when reading words aloud. 相似文献

The Mindful Attention Awareness Scale (MAAS) has the longest empirical track record as a valid measure of trait mindfulness. Most of what is understood about trait mindfulness comes from administering the MAAS to relatively homogenous samples of Caucasian adults. This study rigorously evaluates the psychometric properties of the MAAS among Chinese adolescents attending high school in Chengdu, China. Classrooms from 24 schools were randomly selected to participate in the study. Three waves of longitudinal data (N = 5,287 students) were analyzed. MAAS construct, nomological, and incremental validity were evaluated as well as its measurement invariance across gender using latent factor analyses. Participants' mean age was 16.2 years (SD = 0.7), and 51% were male. The 15-item MAAS had adequate fit to the one-dimensional factor structure at Wave 1, and this factor structure was replicated at Wave 2. A 6-item short scale of the MAAS fit well to the data at Wave 3. The MAAS maintained reliability (Cronbach's α = .89-.93; test-restest r = .35-.52), convergent/discriminant validity, and explained additional variance in mental health measures beyond other psychosocial constructs. Both the 15- and 6-item MAAS scales displayed at least partial factorial invariance across gender. The findings suggest that the MAAS is a sound measure of trait mindfulness among Chinese adolescents. To reduce respondent burden, the MAAS 6-item short-scale provides an option to measure trait mindfulness. 相似文献

Although modern mental health systems increasingly require evidence-based practice (EBP), clinicians continue to object to restrictions on their professional independence, which they may perceive as counterproductive, divisive and even demeaning. In the face of such deep-seated objections, do we really need to strive for an evidence-based approach to supervision? We believe so, and begin our argument by noting a colourful illustration of the problems that can exist in the absence of EBP, those of poor training, therapist drift and weak professional regulation. Next, we present EBP as a mechanism to reduce such unacceptable variability in the way that treatments are delivered. We then apply the lessons from this divisive situation to the practice of clinical supervision, outlining a rationale for an inclusive, synergistic way forward. A number of fundamental psychological motives for this integration are noted, including supervisor training that is informed by practice-based research, corrective feedback on supervision, and a supportive professional system. Illustrative examples are provided in each of these areas. It is concluded that the traditional gulf between research and practice can and should be bridged in relation to supervision. 相似文献

Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed. 相似文献
