Beneficial effects of relaxation on cardiovascular and immune functions and on memory has been implied but an empirical relationship between task performance and anxiety reduction has not been reported. In this study, we investigated whether guided imagery of relatively short duration would decrease S-Anxiety and electroencephalogram Bispectral Index and improve working memory. 42 participants (age: M=39, SD=11, 14 men, 28 women, university students and VA Medical Center employees, recruited by their professor or by fellow employees) underwent relaxation by 16-min. guided imagery or no treatment (control). Spielberger's State-Trait Anxiety Inventory and the WAIS-III Letter-Number Sequencing Test were administered before and after relaxation. S-Anxiety and BIS Index decreased and the Letter-Number test score increased by 30% after relaxation but not in the control group. This score was higher for participants with low anxiety and BIS Index. There was no significant difference between the groups before treatment. The results suggest that guided imagery of short duration produces relaxation as measured by psychological and neurophysiological indices and improves working memory performance. 相似文献

This paper presents the results of a study of syntactically based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control participants. We measured off-line, end-of-sentence, performance (accuracy and reaction time) in two tasks that require comprehension--enactment and sentence-picture matching--and in grammaticality judgment, with whole sentence auditory presentation. We also used sentence-picture matching and grammaticality judgment as tasks in two self-paced listening studies with the same patients to measure on-line performance. In each task and presentation format, we presented sentences that tested the ability to assign and interpret three structural contrasts chosen to examine different basic syntactic operations: actives and passives, subject and object extracted relative clauses, and reflexive pronouns and matched sentences without these elements. We examined these behavioral data to determine patterns of impairment in individual patients and in groups of patients, using correlational analyses, factor analyses, and analyses of variance. The results showed that almost no individual patients had stable deficits referable to the ability to interpret individual syntactic structures, that a variety of structural features contributed to sentence processing complexity both on-line and off-line, that correct responses were associated with normal on-line and errors with abnormal performance, and that the major determinant of performance is a factor that affected performance on all sentence types. The results indicate that the major cause of aphasic impairments of syntactically based comprehension are intermittent reductions in the processing capacity available for syntactic, interpretive, and task-related operations. 相似文献

This study evaluated the clinical significance of measuring between session parental adherence on child and parent outcomes for 51 children (age 4 to 8.5 years) with attention deficit/hyperactivity disorder (ADHD) in a multimodal group training program. Three group treatment conditions: (a) child-only treatment (C1), (c) child and parent training (C2), and (c) C2 + Parent Adherence Measure [PAM (C3)] were compared to assess the clinical significance of measuring parental adherence on child behavioral problems, socialization skills, and parental efficacy. Parents administered the PAM (C3) displayed, in general, better outcomes on child and parent measures than the other two conditions. Results suggest that a multimodal group training program for young children with ADHD is favorable to child group training only. This study offers preliminary support for the clinical utility of measuring parental adherence in a child ADHD multimodal group training program. 相似文献

Compared to the general population, youth in foster care experience multiple psychosocial difficulties due to exceptionally high rates of maltreatment. Many youth in care receive psychological and/or psychotropic treatment but not all require or are willing to accept that level of intervention. For many, a “mental health” approach feels pathologizing. Nevertheless, these youth have suffered maltreatment and interventions to improve their ability to cope with past trauma and their often uncertain present are clearly needed. Cognitively-Based Compassion Training (CBCT) provides an alternative perspective on suffering and can be framed as a wellness intervention that is appropriate for all humans. The present study examined whether a 6-week CBCT intervention would improve psychosocial functioning among adolescents in foster care. Seventy adolescents were randomized to CBCT (twice weekly) or a wait-list condition. Youth were assessed at baseline and after 6 weeks. Groups did not differ on measures of psychosocial functioning following training; however practice frequency was associated with increased hopefulness and a trend for a decrease in generalized anxiety. Qualitative results indicated that participants found CBCT useful for dealing with daily life stressors. Adolescents in care were willing to engage in CBCT. The majority reported CBCT was very helpful and almost all reported they would recommend CBCT to a friend. Participants reported specific instances of using CBCT strategies to regulate emotion, manage stress, or to respond more compassionately towards others. Standardized self-report measures were not sensitive to qualitative reports of improved functioning, suggesting the need for measures more sensitive to the positive changes noted or longer training periods to demonstrate effects. Practical issues surrounding implementation of such programs in high-risk youth populations are identified. Recommendations are provided for further development. 相似文献

This research study explores the relation between measures of creative potential and cognitive and motivational variables, including students' interests, perceptions, and classroom experiences. Surveys were administered to 373 students (N = 373), along with 2 questionnaires, namely the Student Information Sheet (SIS) and the Teacher Encouragement Scale (TES). The students were divided into three groups as High Creative (HC), Average Creative (AC) and Low Creative (LC) on the basis of composite test scores on the tests of creative thinking. The HC students liked Science and Mathematics subjects at school level, whereas the rest of the groups (AC and LC) preferred Indian languages Telugu and Hindi. Surprisingly, all the three groups disliked Social Studies subjects. The top 5 occupations chosen were doctor, teacher, lawyer, engineer, and police constable. When comparing the 3 groups, it is evident that each group had similar aspirations. A high percentage of students, including the HC, were found to be addicted to school achievement. They perceived academic failure as a bad experience in the class and struggled for academic excellence, which was their main goal and interest in life. The highly creative students had more favorable attitudes towards teacher encouragement than the other groups. 相似文献

The present study examined the concurrent validity of a new computer-assisted ADHD screening system, the Pediatric Attention Disorders Diagnostic Screener (PADDS; Pedigo, Pedigo, &; Scott, 2006) in relation to the Test of Variables of Attention (TOVA; Greenberg, 1999), the Conner's Continuous Performance Test- II (CPT-II; Conners &; MHS Staff, 2000), and the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, &; Kenworthy, 2000) in three clinically referred samples of children 6 to 12 years of age. The PADDS is a recently published multidimensional screening measure that incrementally merges computer-administered executive tasks with parent and teacher behavior ratings to aid in the diagnostic decision-making process for youth with attention disorders. To date, no published study has examined the concurrent validity of the PADDS. In a clinic-referred sample of 217 subjects diagnosed with ADHD concurrent validity was assessed through correlation coefficients, paired t-tests (p < .001), and Cohen's d effect sizes. In comparison to the TOVA, the CPT-II, and the BRIEF scales, the PADDS demonstrated strong concurrent validity between conceptually similar scales, providing initial evidence for the concurrent validity of the PADDS. Relative to other measures, the PADDS appears to have some unique scales designed to assess attention and various aspects of executive functioning. 相似文献

Reasoning about concurrent programs involves representing the information that concurrent processes manipulate disjoint portions
of memory. In sophisticated applications, the division of memory between processes is not static. Through operations, processes
can exchange the implied ownership of memory cells. In addition, processes can also share ownership of cells in a controlled
fashion as long as they perform operations that do not interfere, e.g., they can concurrently read shared cells. Thus the
traditional paradigm of distributed computing based on locations is replaced by a paradigm of concurrent computing which is
more tightly based on program structure. Concurrent Separation Logic with Permissions, developed by O’Hearn, Bornat et al.,
is able to represent sophisticated transfer of ownership and permissions between processes. We demonstrate how these ideas
can be used to reason about fine-grained concurrent programs which do not employ explicit synchronization operations to control
interference but cooperatively manipulate memory cells so that interference is avoided. Reasoning about such programs is challenging
and appropriate logical tools are necessary to carry out the reasoning in a reliable fashion. We argue that Concurrent Separation
Logic with Permissions provides such tools. We illustrate the logical techniques by presenting the proof of a concurrent garbage
collector originally studied by Dijkstra et al., and extended by Lamport to handle multiple user processes. 相似文献

Previous research has found that 2‐ to 4‐month‐old infants display a behavioural pattern similar to adult expressions of shyness and related emotions (coyness, bashfulness, embarrassment). In the present study, 6 video‐clips of this pattern and 10 of control patterns varying on a number of features and contexts were presented to 37 judges in a free‐labelling task and in a rating task. Two examples of the target pattern were perceived as expressing primarily shyness and related emotions, three were perceived as expressing primarily happiness with varying degrees of these emotions, and one as expressing several other emotions as well as shyness and related ones. Yet, judges perceived shyness and related emotions almost exclusively in the target pattern, across different contexts and judgement tasks. The three clips perceived as most ‘shy’ were also used in a between‐judges session to control for priming effects. Overall, results suggest that young infants can be perceived as shy, coy, bashful or embarrassed, in particular when their expressive behaviour resembles the relevant adult expressions. Implications for the early development of these emotions are considered. Copyright © 2005 John Wiley Sons, Ltd. 相似文献
