Although the basic function of sleep remains a mystery, insufficient sleep is associated with mood disturbance, fatigue and daytime lethargy, cognitive impairments, daytime behavior problems, academic problems, use of stimulants, work absenteeism, lost work production and an increase in healthcare utilization. The International Classification of Sleep Disorders distinguishes 90 different disorders, many of which can be effectively treated, but when left untreated can be costly in terms of quality of life, health and healthcare cost. Over the past 50 years we have become more effective in measuring sleep and have honed our treatments to better address the sleep disorders that most impact us. This article will focus on the three sleep disorders for which patients most frequently seek care, including insomnia, obstructive sleep apnea syndrome and restless leg syndrome. 相似文献

This study tested how poverty-related stress (PRS), psychological distress, and responses to stress predicted future effortful coping and involuntary stress responses one year later. In addition, we explored age, sex, ethnicity, and parental influences on responses to stress over time. Hierarchical linear modeling analyses conducted with 98 low-income families (300 family members: 136 adults, 82 school-aged children, 82 adolescents) revealed that primary control coping, secondary control coping, disengagement, involuntary engagement, and involuntary disengagement each significantly predicted future use of that response. Primary and secondary control coping also predicted less maladaptive future responses to stress, while involuntary responses to stress undermined the development of adaptive responding. Age, sex, and interactions among PRS and prior coping were also found to predict certain responses to stress. In addition, child subgroup analyses demonstrate the importance of parental modeling of coping and involuntary stress responses, and warmth/nurturance and monitoring practices. Results are discussed with regard to the implications for preventive interventions with families in poverty. 相似文献

Generalized anxiety disorder (GAD) is common in older adults and, although cognitive behavioral therapy (CBT) is an efficacious treatment for late-life GAD, effect sizes are only moderate and attrition rates are high. One way to increase treatment acceptability and enhance current cognitive behavioral treatments for GAD in older adults might be to incorporate religion/spirituality (R/S). The cases presented here illustrate the use of a 12-week modular CBT intervention for late-life anxiety, designed to allow incorporation of R/S elements in accordance with patient preferences. The three women treated using this protocol chose different levels and methods of R/S integration into therapy. All three women showed substantial improvement in worry symptoms, as well as a variety of secondary outcomes following treatment; these gains were maintained at 6-month follow-up. These preliminary results suggest that the incorporation of R/S into CBT might be beneficial for older adults with GAD. Strengths, limitations, and future directions are discussed. 相似文献

There is some evidence for sex differences in habituation in the human fetus, but it is unknown whether this is due to differences in central processing (habituation) or in more peripheral processes, sensory or motor, involved in the response. This study examined whether the sex of the fetus influenced auditory habituation at 33 weeks of gestation, and whether this was due to differences in habituation or in the sensory or motor components using a set of four experiments. The first experiment found that female fetuses required significantly fewer stimulus presentations to habituate than males. The second experiment revealed no difference in the spontaneous motor behaviour of male and female fetuses. The third experiment examined auditory intensity thresholds for the stimuli used to habituate the fetus. No differences in thresholds were found between males and females, although there was inter-individual variability in thresholds. A final experiment, using stimuli individualized for that particular fetus' auditory intensity threshold, found that female fetuses habituated faster than males. In combination, the studies reveal that habituation in the human fetus is affected by sex and this is due to a difference in central 'information processing' of the stimuli rather than peripheral aspects of the response. It is argued that male and female fetuses present different neurobehavioural developmental trajectories, with females more advanced at 33 weeks than males. This study suggests that research examining prenatal behaviour should consider the factor of fetal sex. This may be particularly pertinent where there is an intention to use the results diagnostically. 相似文献

We examined gestural and verbal interactions in 226 mother-infant pairs from Mexican, Dominican, and African American backgrounds when infants were 14 months and 2 years of age, and related these interactions to infants' emerging skills. At both ages, dyads were video-recorded as they shared a wordless number book, a wordless emotion book, and beads and string. We coded mothers' and infants' gestures and language/vocalizations. Each maternal utterance was coded as referential (e.g. 'That's a bead') or regulatory (e.g. 'Put it there'). Mothers reported on infants' gestural, receptive, and productive vocabularies at 14 months, and infants were assessed on receptive language, expressive language, and action sequencing and imitation at 2 years of age. Mothers of the three ethnicities differed in their gesturing, distributions of the two types of language, and coupling of language and gestures. Mothers' ethnicity, language, and gestures were differentially associated with infants' 2-year skills. Mother-infant communicative interactions are foundational to infant learning and development, and ethnic differences in modes of early communication portend divergent pathways in the development of specific skills. 相似文献

Aim: In this study we aimed to investigate whether Chinese international and British home students at a university in the United Kingdom differed in their attitudes towards seeking psychological help. Method: The total sample comprised 323 participants. Participants completed measures to assess their attitudes toward seeking professional psychological help (recognition of need for psychological help, stigma tolerance, interpersonal openness, confidence in mental health practitioners). Results: Chinese students reported significantly less interpersonal openness than that reported by British students. Contrary to prediction, however, no significant group differences were found on any of the other mental health attitudes (i.e. recognition of need for psychological help, confidence in mental health practitioners or stigma tolerance). Within‐group contrasts also showed that Chinese students reported lower scores on interpersonal openness than on stigma tolerance and confidence in mental health practitioners. In contrast, British participants reported less confidence in mental health practitioners and recognition of the need for psychological help than reported for stigma tolerance and interpersonal openness. Conclusion: The findings highlight the need for a greater understanding of students' cultural inclinations toward mental health issues and cultural attitudes that may hinder and/or facilitate students' access and engagement with psychological services in higher education institutions. 相似文献

In two experiments, we examined the effect of intensity and intensity change on judgements of pitch differences or interval size. In Experiment 1, 39 musically untrained participants rated the size of the interval spanned by two pitches within individual gliding tones. Tones were presented at high intensity, low intensity, looming intensity (up-ramp), and fading intensity (down-ramp) and glided between two pitches spanning either 6 or 7 semitones (a tritone or a perfect fifth interval). The pitch shift occurred in either ascending or descending directions. Experiment 2 repeated the conditions of Experiment 1 but the shifts in pitch and intensity occurred across two discrete tones (i.e., a melodic interval). Results indicated that participants were sensitive to the differences in interval size presented: Ratings were significantly higher when two pitches differed by 7 semitones than when they differed by 6 semitones. However, ratings were also dependent on whether the interval was high or low in intensity, whether it increased or decreased in intensity across the two pitches, and whether the interval was ascending or descending in pitch. Such influences illustrate that the perception of pitch relations does not always adhere to a logarithmic function as implied by their musical labels, but that identical intervals are perceived as substantially different in size depending on other attributes of the sound source. 相似文献

The purpose of the current study was to examine how body checking affects men's state body image and state muscle dissatisfaction using an experimental design. Male undergraduates (N = 234) were randomly assigned to a high body checking group, in which they were asked to focus their attention on typically disliked body parts, and a low body checking group, in which they were asked to focus on their bodies as a whole and describe themselves using neutral, nonjudgmental terms. Contrary to initial hypotheses, regardless of condition, participants’ body image satisfaction decreased significantly following the body checking procedure and did not change significantly after a 10-min delay. Additionally, in both conditions, participants’ muscle dissatisfaction did not immediately change, but muscle dissatisfaction increased significantly following the 10-min delay. One mirror exposure session had similar effects on men's body image and muscle dissatisfaction regardless of how they were asked to examine their bodies. 相似文献

Updating body representations from the 3rd person perspectives (3PP) seems to require viewing the real body, unlike when viewing from a 1st person perspective. Here, 3PP updating was investigated through induction of a physically impossible multisensory illusion in which participants viewed real-time 3PP video of themselves having their arm pulled until it stretched to twice its normal length. The illusion elicited the subjective experience that the participant's own arm had been stretched and caused an overestimation of reaching distance, although actual reaches were unaffected. Multisensory illusions from the 3PP can alter body image when applied to real bodies. 相似文献
