Interest in mindfulness-based interventions for children and adolescents is burgeoning, bringing with it the need for validated instruments to assess mindfulness in youths. The present studies were designed to validate among adolescents a measure of mindfulness previously validated for adults (e.g., Brown & Ryan, 2003), which we herein call the Mindful Attention Awareness Scale-Adolescent (MAAS-A). In 2 large samples of healthy 14- to 18-year-olds (N = 595), Study 1 supported a single-factor MAAS-A structure, along with acceptably high internal consistency, test-retest reliability, and both concurrent and incremental validity. In Study 2, with a sample of 102 psychiatric outpatient adolescents age 14-18 years, participants randomized to a mindfulness-based stress reduction intervention showed significant increases in MAAS-A scores from baseline to 3-month follow-up, relative to nonsignificant score changes among treatment-as-usual participants. Increases in MAAS-A scores among mindfulness-based stress reduction participants were significantly related to beneficial changes in numerous mental health indicators. The findings support the reliability and validity of the MAAS-A in normative and mixed psychiatric adolescent populations and suggest that the MAAS-A has utility in mindfulness intervention research. 相似文献

A simple experimental paradigm creates the powerful illusion that one is touching one’s own hand even when the two hands are separated by 15 cm. The participant uses her right hand to administer stimulation to a prosthetic hand while the Examiner provides identical stimulation to the participant’s receptive left hand. Change in felt position of the receptive hand toward the prosthetic hand has previously led to the interpretation that the participant experiences self-touch at the location of the prosthetic hand, and experiences a sense of ownership of the prosthetic hand. Our results argue against this interpretation. We assessed change in felt position of the participant’s receptive hand but we also assessed change in felt position of the participant’s administering hand. Change in felt position of the administering hand was significantly greater than change in felt position of the receptive hand. Implications for theories of ownership are discussed. 相似文献

A wealth of prior research has shown that testing can improve subsequent learning of the initially tested material. In contrast,
only one recent study has shown that an interim test over prior material can improve learning of subsequent new material (i.e.,
an interim-test effect). Five experiments replicated and extended this initial work by exploring the extent to which interim test effects generalize
to complex text material. Participants were prompted to recall each section of an expository text before moving on to study
the next section, or were only prompted to recall after the final section. In all experiments, recall of the final, target
section was greater when prior sections had received interim tests versus no interim tests. Experiment 3 established that the effect was due to interim testing in particular rather than to intervening activity in general. Experiment 4 established that the effect was not due to test expectancy differences. In contrast to prior research, Experiment 4 also provided evidence that the effect is not due to release from proactive interference. We discuss other possible mechanisms
underlying interim-test effects with text, including shifting to more effective encoding strategies. 相似文献

Effective management of chronic diseases (e.g., diabetes) can depend on the extent to which patients can learn and remember disease-relevant information. In two experiments, we explored a technique motivated by theories of self-regulated learning for improving people's learning of information relevant to managing a chronic disease. Materials were passages from patient education booklets on diabetes from NIDDK. Session 1 included an initial study trial, Session 2 included self-regulated restudy, and Session 3 included a final memory test. The key manipulation concerned the kind of support provided for self-regulated learning during Session 2. In Experiment 1, participants either were prompted to self-test and then evaluate their learning before selecting passages to restudy, were shown the prompt questions but did not overtly self-test or evaluate learning prior to selecting passages, or were not shown any prompts and were simply given the menu for selecting passages to restudy. Participants who self-tested and evaluated learning during Session 2 had a small but significant advantage over the other groups on the final test. Secondary analyses provided evidence that the performance advantage may have been modest because of inaccurate monitoring. Experiment 2 included a group who also self-tested but who evaluated their learning using idea-unit judgments (i.e., by checking their responses against a list of key ideas from the correct response). Participants who self-tested and made idea-unit judgments exhibited a sizable advantage on final test performance. Secondary analyses indicated that the performance advantage was attributable in part to more accurate monitoring and more effective self-regulated learning. An important practical implication is that learning of patient education materials can be enhanced by including appropriate support for learners' self-regulatory processes. 相似文献

Conceptualizing and measuring functional impairment related to childhood ADHD, particularly within the rapidly growing, yet
underserved, Latino population, is an important area of research that is in its infancy in the field of psychology. The functional
impairments related to academic achievement, social competence, and familial relations experienced by children with ADHD lead
to long-lasting and debilitating difficulties that adversely affect the individuals themselves, their families, and society.
In addition, limited available research suggests that Latino children are at a great or greater risk for developing ADHD,
although they are much less likely to be identified by their parents as displaying problematic behavior and subsequently are
less likely to receive proper assessment and treatment due to several practical and cultural factors. Fortunately, initial
evidence suggests that the construct of functional impairment may be a more universal notion than the potentially culturally
biased measurement of symptomatology. Therefore, in order to provide the best possible outcomes for all children with ADHD,
research needs to be expanded to include examination of functional impairment related to ADHD, particularly when working with
Latino children and their families. Thus, the primary aim of the current review is to examine and critique how the field of
psychology has understood and measured functional impairment in school-aged Latino children with ADHD to date. Based on information
reviewed, suggestions for moving toward a culturally modified assessment of functional impairment related to ADHD in Latino
children will be proposed. This work is a necessary step toward providing culturally appropriate services for a currently
underserved, yet rapidly growing, Latino population in our country. 相似文献

The association between overall life satisfaction (LS) and relationship satisfaction (RS) was investigated longitudinally
among mothers (N=67,355), using data from the Norwegian Mother and Child Cohort Study (MoBa), conducted by the Norwegian Institute
of Public Health. Data were collected twice during pregnancy, and at 6 and 36 months postpartum. Satisfaction increased during
pregnancy, with RS decreasing immediately following birth and LS showing an initial increase followed by a decrease postpartum.
The results showed that LS and RS levels were quite stable over time (.46-.75), as was their cross-sectional associations
(.42-.59). Structural equation modeling using a cross-lagged longitudinal model evidenced cross-concept cross-time effects
for both LS and RS. The strengths of the cross-effects were asymmetrical and life-phase specific, with RS predicting change
in LS more than LS predicted changes in RS during pregnancy and infancy. Having a satisfying romantic relationship is important
for retaining and increasing future life satisfaction. 相似文献

Male-male competition can shape some behavioral or morphological traits of males. Here we investigate if this competition could play a role in the persistence of the polymorphism of handedness in human populations. A negative frequency-dependent selection mechanism has been hypothesized, based on the fact that left-handed men may benefit from a "surprise" advantage during fighting interactions because they are rare in human populations. This advantage may thereby enhance the probability of survival of left- handed men and/or their reproductive success through an increase in social status. In this study, we first explored the association between hand preference and lifetime fighting behavior in a population of 1,161 French men. No effect of hand preference on the probability of fighting was detected, suggesting that the innate propensity to fight does not differ between left- and right-handers. However, among men who had been involved in at least one fight during their lifetime, left-handers reported significantly more fights than right-handers. To explore the biological basis of this behavior, we also investigated the testosterone concentration in saliva samples from 64 French university students. Consistent with frequencies of fights, we found a significantly higher average testosterone concentration in left-handers than in right-handers. We suggest that these behavioral and hormonal differences may be acquired throughout life due to previous experiences in a social context and may favor the persistence of left-handers in humans. 相似文献

Previous studies examining event-related potentials and evaluative priming have been mixed; some find evidence that evaluative priming influences the N400, whereas others find evidence that it affects the late positive potential (LPP). Three experiments were conducted using either affective pictures (Experiments 1 and 2) or words (Experiment 3) in a sequential evaluative priming paradigm. In line with previous behavioral findings, participants responded slower to targets that were evaluatively incongruent with the preceding prime (e.g., negative preceded by positive) compared to evaluatively congruent targets (e.g., negative preceded by negative). In all three studies, the LPP was larger to evaluatively incongruent targets compared to evaluatively congruent ones, and there was no evidence that evaluative incongruity influenced the N400 component. Thus, the present results provide additional support for the notion that evaluative priming influences the LPP and not the N400. We discuss possible reasons for the inconsistent findings in prior research and the theoretical implications of the findings for both evaluative and semantic priming. 相似文献
