This study aimed to test the hypothesis that impairments of temporal duration processing after frontal lobe lesions reflect deficits in executive monitoring functions rather than a domain-specific deficit in the maintenance of duration information in working memory. Patients with frontodorsal lesions, clinical controls with post-central lesions, and healthy controls performed recognition and classification tasks, which should allow for testing maintenance and monitoring functions, respectively. Results showed mild non-selective impairments of the frontal patients on both temporal and spatial recognition tasks, but a marked selective degradation on temporal classification while performance on spatial classification was unimpaired. This suggests that maintenance of duration information in working memory after frontal lesions is basically preserved but that, depending on executive task characteristics, there is a specific deficit in the strategic organization of this type of information. 相似文献

Objective: To examine components of family-centered care in families' stories about treatment decision making for their child with ADHD. Method: Twenty-eight families participated in qualitative interviews that addressed families' perspectives on (a) the treatment decision-making process, (b) the cause and impact of their child's symptoms, and (c) treatment goals and preferences. Results: The majority of families preferred to be primary or shared decision makers regarding treatment decisions. Families' perspectives on the cause of the child's symptoms varied and often were not consistent with a biomedical framework. Families described multiple areas of impairment on child, family relationships, and family functioning. Perspectives toward evidence-based treatments were mixed, with families also expressing interest in and pursuing interventions not delineated in current treatment guidelines. Conclusion: These findings reinforce the importance of eliciting families' perspectives and involving these important stakeholders in shared decision making as critical components of family-centered care for children with ADHD. 相似文献

Free association is a task that requires a subject to express the first word to come to their mind when presented with a certain cue. It is a task which can be used to expose the basic mechanisms by which humans connect memories. In this work, we have made use of a publicly available database of free associations to model the exploration of the averaged network of associations using a statistical and the adaptive control of thought–rational (ACT-R) model. We performed, in addition, an online experiment asking participants to navigate the averaged network using their individual preferences for word associations. We have investigated the statistics of word repetitions in this guided association task. We find that the considered models mimic some of the statistical properties, viz the probability of word repetitions, the distance between repetitions and the distribution of association chain lengths, of the experiment, with the ACT-R model showing a particularly good fit to the experimental data for the more intricate properties as, for instance, the ratio of repetitions per length of association chains. 相似文献

In this 2‐week diary study, with 105 employees providing data on a total of 476 days, we examined relationships between the amount of time spent on volunteer work activities during leisure time, psychological non‐work experiences in the evening (i.e. recovery experiences of psychological detachment from work and mastery as well as need satisfaction), and work outcomes during the following working day (i.e. positive and negative affect, and active listening). Results confirmed the hypothesized positive relationships between the amount of time spent on volunteer work activities and psychological detachment from work, mastery experiences, and need satisfaction in the evening. Psychological detachment from work in the evening was positively related to active listening during the following working day. Need satisfaction in the evening was negatively related to negative affect and positively related to active listening during the following working day. The amount of time spent on volunteer work activities was negatively related to negative affect during the following working day. This relationship was mediated by need satisfaction in the evening. 相似文献

In this study the effects of virtual reality exposure therapy (VRET) were investigated in patients with acrophobia. Feelings of presence in VRET were systematically varied by using either a head-mounted display (HMD) (low presence) or a computer automatic virtual environment (CAVE) (high presence). VRET in general was found to be more effective than no treatment. No differences were found in effectiveness between VRET using an HMD or CAVE. Results were maintained at 6 months follow-up. Results of VRET were comparable with those of exposure in vivo (Cyberpsychology and Behavior 4 (2001) 335). In treatment completers no relationship was found between presence and anxiety. Early drop-outs experienced less acrophobic complaints and psychopathology in general at pre-test. They also experienced less presence and anxiety in the virtual environment used in session one as compared to patients that completed VRET. 相似文献

The objective of this study was to examine the level of agreement between child- and caregiver-reports of the child’s psychosocial
problems presenting to a Pediatric Emergency Department (PED) using a validated screening tool. This was an anonymous, prospective,
cross-sectional, multi-informant (child and caregiver) study assessing cognitive, emotional, and behavioral problems and physical
complaints in children and adolescents presenting to a PED. Three-hundred and fifty-eight children and adolescents (8–18 years
old) and their caregivers participated. Children completed the Youth-Pediatric Symptom Checklist (PSC-Y), while their caregivers
completed the Pediatric Symptom Checklist–35 (PSC-35) to measure psychosocial impairment. The child’s physical complaints
(e.g., chief complaint, chronicity, other medical problems, medications) and demographic information were assessed using an
investigator-developed patient background questionnaire completed by the caregivers. Physical complaints (e.g., chief complaint,
chronicity, other medical problems, medications) were assessed using an investigator-developed patient background questionnaire.
Agreement between child- and caregiver- reports was analyzed using Cohen’s kappa coefficient. Differences between child and
caregiver-reported scores were determined by t-tests. Poor to moderate agreement was found between child- and caregiver-reports of attention problems (κ = .355), externalizing
problems (κ = .340), internalizing problems (κ = .065), and total PSC score (κ = .410). Both children and caregivers should
complete the psychosocial screener to maximize the accuracy of assessment and the identification of impairment. 相似文献

Debate continues about the accuracy of military suicide reporting due to concerns that some suicides may be classified as accidents to minimize stigma and ensure survivor benefits. We systematically reviewed records for 998 active duty Army deaths (510 suicides; 488 accident, homicide, and undetermined deaths; 2005‐2009) and, using research criteria, reclassified 8.2% of the nonsuicide cases to definite suicide (1), suicide probable (4), or suicide possible (35). The reclassification rate to definite suicide was only 0.2% (1/488). This low rate suggests that flagrant misclassification of Army deaths is uncommon and surveillance reports likely reflect the “true” population of Army suicides. 相似文献
