Australian health professional bodies promote the use of respite to ease carer burden, following well‐established findings that carers often face physical, mental, social, and financial strain while providing informal care. This narrative review examined the use and impacts of respite for older clients, with a particular focus on Australian research and on dementia respite. It was found that despite reports of high satisfaction from caregivers with respite use, barriers, such as caregiver concerns for the well‐being and safety of the care recipient during respite, limited flexibility for short‐notice respite booking, and low provision of support and education post respite, impacted on the accessibility and efficacy of respite care. It was concluded that respite care needs to move away from a custodial model to a more psychological model of care, and that more natural and flexible models (e.g., host family respite), integrated with increased post‐respite support and psychosocial education, are likely to be beneficial and need further evaluation. 相似文献

The article explores integration of knowledge-enabling digital technology into community functions through the development
of local Digital Communities of Practice. This analysis includes both general considerations—in terms of domain, community, and practice dimensions—as well as results from an exploratory research project in Minnesota. The domain is described as integrated deployment
of virtual services (education, human services, government) in local communities; the community is comprised of the local
stakeholders and residents that would use or benefit from such services; and the practice is considered as a decision-making
processes for designing and deploying these services. The paper concludes with research and policy considerations for providing
an enduring source of knowledge about local virtual services, needs, and solutions.

Nicotine functions as a negative feature in a Pavlovian discriminated goal-tracking task. Whether withholding of responding to the conditional stimulus (CS) reflects nicotine functioning as a conditioned inhibitor is unknown. Accordingly, the present research sought to determine whether nicotine trained as a negative feature passed the retardation-of-acquisition and summation tests, thus characterizing it as a pharmacological (interoceptive) conditioned inhibitor. In the retardation test, rats received either nicotine (0.4 mg/kg) or chlordiazepoxide (5 mg/kg) negative feature training in which the drug state signaled when a 15-sec light CS would not be paired with sucrose; light was paired with sucrose on intermixed saline sessions. Following acquisition of the discrimination, both groups received nicotine CS training in which sucrose was intermittently available on nicotine but not intermixed saline sessions. Acquisition of conditioned responding to the nicotine CS was slower in the nicotine negative feature group than in the chlordiazepoxide negative feature group. In the summation test, rats were assigned to either the nicotine negative feature group or a pseudoconditioning control. In this control, the light CS was paired with sucrose on half the nicotine and half the saline sessions. Both groups also received excitatory training in which a white noise CS was paired with sucrose. The summation test consisted of presenting the white noise in conjunction with nicotine. Conditioned responding evoked by the white noise was decreased in the negative feature but not the pseudoconditioning group. Combined, the results provide the first evidence that an interoceptive stimulus (nicotine) can become a conditioned inhibitor. 相似文献

Contextual stimulus control over instrumental drug-seeking behavior relies on the reconsolidation of context-response-drug associative memories into long-term memory storage following retrieval-induced destabilization. According to previous studies, the basolateral amygdala (BLA) and dorsal hippocampus (DH) regulate cocaine-related memory reconsolidation; however, it is not known whether these brain regions interact or independently control this phenomenon. To investigate this question, rats were trained to lever press for cocaine reinforcement in a distinct environmental context followed by extinction training in a different context. Rats were then briefly re-exposed to the cocaine-paired context to destabilize cocaine-related memories, or they were exposed to an unpaired context. Immediately thereafter, the rats received unilateral microinfusions of anisomycin (ANI) into the BLA plus baclofen/muscimol (B/M) into the contralateral (BLA/DH disconnection) or ipsilateral DH, or they received contralateral or ipsilateral microinfusions of vehicle. They then remained in their home cages overnight or for 21 d, followed by additional extinction training and a test of cocaine-seeking behavior (nonreinforced active lever responding). BLA/DH disconnection following re-exposure to the cocaine-paired context, but not the unpaired context, impaired subsequent drug context-induced cocaine-seeking behavior relative to vehicle or ipsilateral ANI + B/M treatment. Prolonged home cage stay elicited a time-dependent increase, or incubation, of drug-context-induced cocaine-seeking behavior, and BLA/DH disconnection inhibited this incubation effect despite some recovery of cocaine-seeking behavior. Thus, the BLA and DH interact to regulate the reconsolidation of cocaine-related associative memories, thereby facilitating the ability of drug-paired contexts to trigger cocaine-seeking behavior and contributing to the incubation of cocaine-seeking behavior. 相似文献

A randomized controlled trial of Student Success Skills (SSS) was conducted to determine the effect of the classroom program on Grade 5 students’ (N = 4,305) standardized test scores and proximal socioemotional variables associated with academic achievement. The SSS program was delivered by school counselors and reinforced through cuing and coaching by classroom teachers, which reflects the advocating student‐within‐environment approach to school counseling (Lemberger‐Truelove & Bowers, 2018). Hierarchical linear modeling analyses revealed the SSS program affected the treatment students’ behavioral engagement, disruption, assertion, cooperation, and test anxiety but did not result in a statistically significant difference on the participants’ reading and mathematics test scores. Implications for practice and further research are discussed. 相似文献

The mechanisms contributing to the occurrence of auditory hallucinations have not been fully described, although many researchers agree that they may result from some type of misattributed cognitive event. A number of authors have shown that this misattribution may be influenced by ‘top down' processes such as beliefs and expectations. This type of cognitive bias has also been implicated in other psychological disorders. One area of focus, particularly within the anxiety disorders, has been on metacognitive beliefs and their role in the occurrence and maintenance of symptoms. Metacognitive beliefs have not been widely investigated in psychosis and tools to investigate them have not been developed. In this study, a metacognitions questionnaire [MCQ; Cartwright-Hatton, S., & Wells, A. (1997). Journal of Anxiety Disorders, 11(3),279–296.] (previously used with anxiety disorders) was modified and used to assess metacognitive beliefs with schizophrenic patients. Metacognitive beliefs were compared between schizophrenic patients who were currently experiencing auditory hallucinations and schizophrenic patients who had never had hallucinations. A group of patients with anxiety disorders and a group of non-patients were used as controls. Hallucinating and non-hallucinating schizophrenics scored significantly higher than both the non-patient group and the anxiety patient group on the amount to which they believed their thoughts should be consistent with each other. Hallucinators and anxiety controls had significantly lower confidence in their cognitive processes than non-hallucinating schizophrenics and normal controls. The significance of these findings are discussed in relation to the literature on cognitive processes in hallucinations. 相似文献

Data are reported from 3,213 research eyewitnesses confirming that accurate eyewitness identifications from lineups are made faster than are inaccurate identifications. However, consistent with predictions from the recognition and search literatures, the authors did not find support for the "10-12-s rule" in which lineup identifications faster than 10-12 s maximally discriminate between accurate and inaccurate identifications (D. Dunning & S. Perretta, 2002). Instead, the time frame that proved most discriminating was highly variable across experiments, ranging from 5 s to 29 s, and the maximally discriminating time was often unimpressive in its ability to sort accurate from inaccurate identifications. The authors suggest several factors that are likely to moderate the 10-12-s rule. 相似文献

The U.S. Department of Justice released the first national guide for collecting and preserving eyewitness evidence in October 1999. Scientific psychology played a large role in making a case for these procedural guidelines as well as in setting a scientific foundation for the guidelines, and eyewitness researchers directly participated in writing them. The authors describe how eyewitness researchers shaped understanding of eyewitness evidence issues over a long period of time through research and theory on system variables. Additional pressure for guidelines was applied by psychologists through expert testimony that focused on deficiencies in the procedures used to collect the eyewitness evidence. DNA exoneration cases were particularly important in leading U.S. Attorney General Janet Reno to notice the eyewitness literature in psychology and to order the National Institute of Justice to coordinate the development of national guidelines. The authors describe their experience as members of the working group, which included prosecutors, defense lawyers, and law enforcement officers from across the country. 相似文献
