It is well acknowledged that deployment can have a significant impact on military personnel; however, the effect on their partners who remain on the homefront is less researched. This meta-synthesis aimed to explore the experience of deployment for partners of military personnel to provide a greater understanding of the challenges and responses involved for them. Noblit and Hare's (1988) meta-ethnographic approach was adopted to synthesize 11 qualitative studies that met the inclusion and exclusion criteria. The five core concepts to emerge from the meta-synthesis were the multitude of emotions; methods of coping; communication with their partner; relentless responsibilities; and positive outcomes. These findings provide a developed understanding of how challenges of deployment are managed, including negative outcomes and protective psychological responses and behaviors. The limitations of these findings are discussed, as are clinical implications and recommendations for future research.  相似文献

This exploratory paper considers the spaces where hits take place within Britain. It concentrates on those hits that have occurred on the doorstep of the victim and offers analysis of why this location might be chosen. It suggests an emerging modus operandi (MO) of doorstep hits and how knowledge of this MO might be useful to law enforcement. Two cold cases are re‐considered in light of this MO.

Posttraumatic stress disorder (PTSD) is associated with executive functioning deficits, including disruptions in working memory (WM). Recent studies suggest that attention training reduces PTSD symptomatology, but the underlying neural mechanisms are unknown. We used high-density magnetoencephalography (MEG) to evaluate whether attention training modulates brain regions serving WM processing in PTSD. Fourteen veterans with PTSD completed a WM task during a 306-sensor MEG recording before and after 8 sessions of attention training treatment. A matched comparison sample of 12 combat-exposed veterans without PTSD completed the same WM task during a single MEG session. To identify the spatiotemporal dynamics, each group’s data were transformed into the time-frequency domain, and significant oscillatory brain responses were imaged using a beamforming approach. All participants exhibited activity in left hemispheric language areas consistent with a verbal WM task. Additionally, veterans with PTSD and combat-exposed healthy controls each exhibited oscillatory responses in right hemispheric homologue regions (e.g., right Broca’s area); however, these responses were in opposite directions. Group differences in oscillatory activity emerged in the theta band (4–8 Hz) during encoding and in the alpha band (9–12 Hz) during maintenance and were significant in right prefrontal and right supramarginal and inferior parietal regions. Importantly, following attention training, these significant group differences were reduced or eliminated. This study provides initial evidence that attention training improves aberrant neural activity in brain networks serving WM processing.  相似文献

Lang's bioinformational theory of mental imagery proposes that mental imagery and external stimuli engage emotional information-processing systems in similar ways. However, the positive and negative systems are thought to be distinct, so this similarity is likely to show a valence-specific effect. Therefore, we hypothesized that an individual's ability to construct vivid positive, but not negative, mental imagery would predict positive emotional responding to positive visual stimuli, independently of depressive symptoms. Our stimuli were pictures collected through Project Soothe for possible use in psychotherapy ( www.projectsoothe.com ); as these pictures were intended to induce soothing emotion, we hypothesized that theoretically linked variables Self-compassion and Self-criticism would also predict positive responding to the stimuli. A total of 214 participants completed an online study including validated questionnaire measures, mental imagery tasks, and a picture-rating exercise. Only Positive Imagery Vividness and Self-compassion were significant predictors of positive responding to the soothing pictures, even controlling for depressive symptoms, and Negative and General Imagery Vividness. These findings support Lang's theory and provide evidence for individual differences in a positive processing tendency shared across mental imagery-based and perceptual representations. As this relationship is distinct from depressive symptoms, future imagery-based psychotherapies might aim to influence this positive processing tendency.  相似文献

For more than a century, psychologists have been intrigued by the idea that mental representations of perceived human actions are closely connected with mental representations of performing those same actions. In this article, connections between input and output representations are considered in terms of the potential for imitation. A broad range of evidence suggests that, for imitatible stimuli, input and output representations are isomorphic to one another, allowing mutual influence between perception and motoric planning that is rapid, effortless, and possibly obligatory. Thus, the cognitive consequences of imitatibility may underlie such diverse phenomena as phoneme perception; imitation in neonates; echoic memory; stimulus-response compatibility; conduction aphasia; maintenance rehearsal; and a variety of developmental and social activities such as language acquisition, social learning, empathy, and monitoring one's own behavior.  相似文献

This paper examines the standard view of realization operative incontemporary philosophy of mind, and proposes an alternative, generalperspective on realization. The standard view can be expressed, insummary form, as the conjunction of two theses, the sufficiency thesis andthe constitutivity thesis. Physicalists of both reductionist and anti-reductionist persuasions share a conception of realization wherebyrealizations are determinative of the properties they realize and physically constitutive of the individuals with those properties. Centralto the alternative view that I explore here is the idea that the requisite,metaphysically robust notion of realization is ineliminably context-sensitive. I shall argue that the sufficiency and constitutivity theses aretypically not jointly satisfied by any one candidate realizer, and that goingcontext-sensitive in one's metaphysics is preferable to the standard view.The context-sensitive views developed here are implicit in a range ofcommon views in both the philosophy of mind and the philosophy of biology,even if they have not been explicitly articulated, and even though theyundermine other views that are commonly endorsed.  相似文献

Eye Movement Desensitization and Reprocessing (EMDR) has been shown to be effective for treating posttraumatic stress disorder, but its efficacy as a stress management tool for normal individuals in highly stressful occupations has not been demonstrated. Sixty-two police officers were randomly assigned to either EMDR or a standard stress management program (SMP), each consisting of 6 hours of individualized contact. At completion, officers in the EMDR condition provided lower ratings on measures of PTSD symptoms, subjective distress, job stress, and anger; and higher marital satisfaction ratings than those in SMP. The effects of EMDR were maintained at the 6-month follow-up, indicating enduring gains from a relatively brief treatment regimen for this subclinical sample of officers who were experiencing some level of stress from their job.  相似文献

The purpose of this study was twofold: to determine (1) the degree to which specific qualities of maternal touch may contribute to the low birth weight infant's emotional and behavioural problems as well as social adaptation, and (2) the relationship between maternal touch and a mother's other caregiving behaviour. The sample included 114 socioculturally diverse infants and their mothers who were videotaped during an infant feeding when the baby was 3 months old. This videotape was analysed to assess dimensions of mother–infant interaction, including maternal touch. Data on perinatal risk and the mother's acceptance versus rejection of the infant were also acquired. Social adaptation and emotional/behavioural problems were measured when the child was 2 years of age. Hierarchical regression analyses indicated that maternal touch accounted for 15% of the variance in the likelihood of a child having emotional/behavioural problems at age 2. Children who received more nurturing touch had significantly fewer internalizing problems (such as depression) while children receiving both more frequent touch and harsh touch had more externalizing problems (such as aggressive behaviour). Infants who were less responsive to their caregivers were especially at risk of developing aggressive/destructive behaviour as a result of frequent touch. But less responsive infants also appeared to benefit most from greater use of diverse types of maternal touch, accounting for 6% of the variance in superior adaptive behaviour at age 2. Nurturing touch was the only quality that showed even a modest relationship to other caregiving behaviour, suggesting that touch may play a distinct role in the infant's psychosocial development.

A familicide is a multiple-victim homicide incident in which the killer's spouse and one or more children are slain. National archives of Canadian and British homicides, containing 109 familicide incidents, permit some elucidation of the characteristic and epidemiology of this crime. Familicides were almost exclusively perpetrated by men, unlike other spouse-killings and other filicides. Half the familicidal men killed themselves as well, a much higher rate of suicide than among other uxoricidal or filicidal men. De facto unions were overrepresented, compared to their prevalence in the populations-at-large, but to a much lesser extent in familicides than in other uxoricides. Stepchildren were overrepresented as familicide victims, compared to their numbers in the populations-at-large, but to a much lesser extent than in other filicides; unlike killers of their genetic offspring, men who killed their stepchildren were rarely suicidal. An initial binary categorization of familicides as accusatory versus despondent is tentatively proposed. © 1995 Wiley-Liss, Inc.  相似文献
