The scope of sustained military operations in Iraq and Afghanistan has placed great demands on the Armed Forces of the United States, and accordingly, military families have been faced with deployments in more rapid succession than ever before. When military parents fulfill occupational duties during wartime, military children and families face multiple challenges, including extended separations, disruptions in family routines, and potentially compromised parenting related to traumatic exposure and subsequent mental health problems. Such challenges can begin to exert a significant toll on the well-being of both individuals and relationships (e.g., marital, parent–child) within military families. In order to respond more effectively to the needs of military families, it is essential that mental health clinicians and researchers have a better understanding of the challenges faced by military families throughout the entire deployment experience and the ways in which these challenges may have a cumulative impact over multiple deployments. Moreover, the mental health field must become better prepared to support service members and families across a rapidly evolving landscape of military operations around the world, including those who are making the transition from active duty to Veteran status and navigating a return to civilian life and those families in which parents will continue to actively serve and deploy in combat zones. In this article, we utilize family systems and ecological perspectives to advance our understanding of how military families negotiate repeated deployment experiences and how such experiences impact the well-being and adjustment of families at the individual, dyadic, and whole family level.  相似文献

This study investigated the cognitive organization of the human body representation and its relationship to other object representations. It addressed whether (1) all objects and their parts were organized similarly, (2) animate objects and their parts were organized differently from inanimate objects and their parts, and (3) the human body was organized differently from all other objects. The relations among the parts of three exemplar objects (human body, bear, and bicycle) were examined. Participants performed a series of sorting tasks using stimulus cards illustrating various part and part combinations of these objects; the cards were constructed so that the same strategies could be used to categorize all three objects. Dissimilarity data were analysed using multidimensional scaling techniques. Results indicated that the human body was organized differently from the other objects, and that categorization did not follow the animate–inanimate distinction. Although animate objects were represented more on their visual characteristics and inanimate objects were represented more on functional characteristics, the human body was represented on its ability to perform actions. Representations of the other objects suggested that their organization was embodied in that they appear to be shaped by how the human body interacts, or doesn't interact, with the object.  相似文献

Previous research on counterfactual thoughts about prevention suggests that people tend to focus on enabling rather than causing events and controllable rather than uncontrollable events. Two experiments explore whether counterfactual thinking about enablers is distinct from counterfactual thinking about controllable events. We presented participants with scenarios in which a cause and an enabler contributed to a negative outcome. We systematically manipulated the controllability of the cause and the enabler and asked participants to generate counterfactuals. The results indicate that when only the cause or the enabler is controllable participants undid the controllable event more often. However, when the cause and enabler are matched in controllability participants undid the enabler slightly more often. The findings are discussed in the context of the mental model, functional and judgement dissociation theories as well as previous research on counterfactual thinking. The importance of controllability and possible reasons for the special role of enablers are considered.  相似文献

This review explores risk factors that may make a young person vulnerable to being groomed online. Even though research in this area is extremely limited, adolescents appear to be the age group most vulnerable to online grooming. Other vulnerabilities appear to be consistent with those associated with offline sexual abuse. The review suggests that behaviors specific to online grooming include: engaging in risk taking behavior online, high levels of internet access, and lack of parental involvement in the young person's internet use. Vulnerabilities to carry out these types of behavior and be more exposed to the risk of online grooming, are set within the context of the Ecological Model of child protection, consisting of: individual, family, community, and cultural risk factors. Patterns of vulnerability regarding living environment, ethnicity, socioeconomic status, and personality are tentative, but are often interconnected. The more risk taking behaviors the young person carries out, plus greater levels of vulnerability factors, the less resilient they are likely to be towards protecting themselves against online grooming. A protective factor appears to be parental involvement in their child's use of the internet. Therefore, this, in combination with internet safety education at school, is encouraged.  相似文献

Research has begun to document the negative organizational consequences of knowledge hiding, or the intentional attempt to conceal knowledge, among employees. However, different knowledge hiding behaviours exist, and we explore whether some types of knowledge hiding are more harmful than others. Although theory would suggest that knowledge hiders rationalize their behaviours and fail to anticipate the negative consequences of their behaviours, we found that they did anticipate harmed relationships and retaliation. In addition, targets of knowledge hiding did not always construe the behaviour as harmful or as necessitating retaliation. Overall, our research suggests that not all knowledge hiding is equally harmful. Some types of knowledge hiding may actually enhance the relationships between colleagues and might break the cycle of knowledge hiding in organizations.  相似文献

Researchers have reported that bereaved people often continue to sense the presence of the deceased. A particular collection of such experiences can be identified as instilling a perception that the deceased person is in some manner present in the company of the bereaved person. The aim of the current review was to synthesise the results on this topic to provide a comprehensive over-view for practitioners working with bereaved people who report these experiences. The studies were reviewed in terms of the nature of the experiences described, the provision of explanatory models to understand the significance of these experiences, describing any culturally specific aspects of these experiences, discussion of the personal impact of having the experiences, and for recommendations of how people who have these experiences can be supported.  相似文献

ABSTRACT

Sex differences in patterns of cognitive test performance have been attributed to factors, such as sex hormones or sexual dimorphisms in brain structure, that change with normal aging. The current study examined sex differences in patterns of cognitive test performance in healthy elderly individuals. Cognitive test scores of 957 men and women (age 67–89), matched for overall level of cognitive test performance, age, education, and depression scale score, were compared. Men and women were indistinguishable on tests of auditory divided attention, category fluency, and executive functioning. In contrast, women performed better than men on tests of psychomotor speed and verbal learning and memory, whereas men outperformed women on tests of visuoconstruction and visual perception. Our finding that the pattern of sex differences in cognition observed in young adults is observed in old age has implications for future studies of both healthy elderly individuals and of those with cognitive disorders.  相似文献

Eighty-eight graphic artists in their 60s, 70s, and 80s, nominated as creative by 154 prominent artists, completed an open-ended questionnaire about aging and its effect on their work. Four questions referred to changes in creativity in terms of the quality and quantity of work, sources of new ideas (originality), and approaches to art (style). The artists also were asked about the impact of physical and sensory losses on their work, and on their differences from younger artists. The artists also rated the quality and quantity of their past, present, and anticipated work. A content analysis of the artists' written comments to the 6 questions, and the ratings, gave a highly positive picture of aging's influence on art. Quality and quantity were reported as improving with age, as were the artists' ideas about, and approaches to, art. The presumed handicaps of aging largely were irrelevant or overcome. Few differences were reported with younger artists. Positive views of aging held equally for both men and women, and across the 3 age groups. The optimistic portrait of aging reflected by this sample of visual artists is discussed in terms of its relevance to other kinds of artists and nonartists; the consequences of early retirement; and the place of active older persons, especially artists, in studies of cognitive development.  相似文献

In order to provide the best genetic counseling possible for women who learn of a diagnosis of Down syndrome prenatally, we sought to assess the timing of the decision to continue a pregnancy and the satisfaction these women had with learning this information. Fifty-six mothers of children with Down syndrome diagnosed prenatally between 2007 and 2010 completed a survey regarding their experience with decision-making after prenatal diagnosis. Approximately one third (17/56) of participants reported they knew before getting pregnant that they would not terminate for any reason, and almost half of the participants (24/56) reported they did not decide to continue their pregnancy until after the diagnosis. Many participants (82 %; 42/56) stated that learning the diagnosis during pregnancy increased their anxiety. The majority (88 %; 45/56) also reported that if they could do it over again, they would undergo prenatal testing for preparation purposes, despite increased anxiety. Religious and spiritual beliefs as well as feeling attached to the baby were the personal factors that had the greatest impact on most women’s decision-making. Despite increased anxiety caused by learning the diagnosis prenatally, most women favored prenatal diagnosis as it allowed them time to process the information and prepare for the birth of their child.  相似文献
