Mindfulness training for loneliness among Chinese college students: A pilot randomized controlled trial 下载免费PDF全文
Loneliness has been found to predict a wide range of physical and mental health problems. It is suggested that China's One‐Child Policy places young Chinese people at a particularly high risk for loneliness. Although loneliness is most prevalent in late adolescence and early adulthood, interventions have primarily targeted children or older adults with limited success. The current study examines a pilot randomized controlled trial of a mindfulness training program among Chinese college students. Participants with elevated loneliness (N = 50, ages 17–25) were randomized into either an 8‐week mindfulness training or a control group. Self‐reported measures of loneliness and mindfulness were administered at baseline and posttest. The training group also completed a program evaluation form and a 3‐month follow‐up assessment. Results provided preliminary evidence indicating that the intervention was feasible and effective at reducing loneliness among Chinese college students. Limitations and future directions were discussed. 相似文献

Displacement of the cerebellar tonsils in Chiari type I malformation (CMI) can affect functions controlled by the cerebellum and brainstem. While playing an integral role in the control of movement, the cerebellum also has widespread cortical connections, influencing a range of cognitive process. A systematic literature review was conducted to examine the relationship between cognition and CMI, assessing evidence for general or domain-specific cognitive change. The search protocol examined the AMED, CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and Scopus databases. Articles meeting the following criteria were included in this review (i) examined children or adults with a clinically defined diagnosis of CMI, (ii) assessed cognitive function with a prospective examination, (iii) included at least one standardized instrument designed to measure general or specific domains of cognitive function, and (iv) were published in English in a peer-reviewed journal. Twelve articles were identified, including 783 cases aged 3 months to 64 years. General cognition, processing speed, and learning and memory appeared less affected, while language deficits appeared to diminish with age. Executive dysfunction was the most commonly reported cognitive impairment, while attention and working memory, and visuospatial and perceptual skills also appeared vulnerable. Numerous methodological limitations were identified that should be considered in interpreting the impact of CMI and planning future investigations. Overall, there is currently insufficient evidence to describe a valid and reliable profile of cognitive impairment in CMI. Further research is required to confirm these preliminary psychometric results and integrate them with pathophysiological models 相似文献

We present the generalized signal detection theory (GSDT), where familiarity is described by a sparse binomial distribution of binary node activity rather than by normal distribution of familiarity. Items are presented in a distributed representation, where each node receives either noise only, or signal and noise. An old response (i.e., a “yes” response) is made if at least one node receives signal plus noise that is larger than the activation threshold, and item variability is determined by the distribution of activated nodes as the threshold is varied. A distinct representation leads to better performance and a lower ratio of new to old item variability, than a more distributed and less distinct representations. Here we apply the GSDT to empirical data on verbal and olfactory memory and suggest that verbal memory relies on a distinct neural item representation, whereas olfactory memory has a fuzzy neural representation leading to poorer memory and inducing a larger ratio of new to old item variability. 相似文献
