Two different procedures were used to measure the difficulties of Scholastic Aptitude Test items: a new distribution-free procedure that uses periodic functions and LOGIST, a well-developed optimization procedure that fits a logistic model. Despite the fact that the two procedures used different data in very different ways, they obtained virtually the same numbers. The new method exemplifies “fundamental” psychological measurement in as much as it is based on counting and ordinal properties of data only. 相似文献

The objective of this study was to compare efficacy of two meditation protocols for treating patients with obsessive-compulsive disorder (OCD). Patients were randomized to two groups-matched for sex, age, and medication status-and blinded to the comparison protocol. They were told the trial would last for 12 months, unless one protocol proved to be more efficacious. If so, groups would merge, and the group that received the less efficacious treatment would also be afforded 12 months of the more effective one. The study was conducted at Children's Hospital, San Diego, Calif. Patients were selected according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised (DSM-III-R) criteria and recruited by advertisements and referral. At baseline, Group 1 included 11 adults and 1 adolescent, and Group 2 included 10 adults. Group 1 employed a kundalini yoga meditation protocol and Group 2 employed the Relaxation Response plus Mindfulness Meditation technique. Baseline and 3-month interval testing was conducted using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Symptoms Checklist-90-Revised Obsessive Compulsive (SCL-90-R OC) and Global Severity Index (SCL-90-R GSI) scales, Profile of Moods scale (POMS), Perceived Stress Scale (PSS), and Purpose in Life (PIL) test. Seven adults in each group completed 3 months of therapy. At 3 months, Group 1 demonstrated greater improvements (Student's independent groups t-test) on the Y-BOCS, SCL-90-R OC and GSI scales, and POMS, and greater but nonsignificant improvements on the PSS and PIL test. An intent-to-treat analysis (Y-BOCS) for the baseline and 3-month tests showed that only Group 1 improved. Within-group statistics (Student's paired t-tests) showed that Group 1 significantly improved on all six scales, but Group 2 had no improvements. Groups were merged for an additional year using Group 1 techniques. At 15 months, the final group (N=11) improved 71%, 62%, 66%, 74%, 39%, and 23%, respectively, on the Y-BOCS, SCL-90-R OC, SCL-90-R GSI, POMS, PSS, and PIL; P<0.003 (analysis of variance). This study demonstrates that kundalini yoga techniques are effective in the treatment of OCD. 相似文献

The theory offered in this article articulates the position that the cognitive skills manifested by children are those which are necessary preconditions for spirituality. I argue that psychological theories that posit a hierarchical stage theory of cognition and affect are grounded on premises, which devalue these skills. Theories of children's spirituality have foundered in their ability to appreciate that children's cognition is organized through structures that are quintessential to spirituality, due to their misplaced reliance on these theories. I offer a critique of traditional psychological approaches and an alternative model of children's cognition, which reveals that the cognitive capacities of children are essential to the phenomenology of spirituality. 相似文献

Unawareness of visual and sensorimotor defects: A hypothesis 总被引:2,自引:0,他引:2
A theory is proposed to account for unawareness of blindness, hemianopsia, and hemiplegia, and for phantom limb after amputation. It is assumed that interruption of a sensory pathway at any level--from peripheral nerve to primary sensory cortex--is not associated with any immediate sensory experience that uniquely specifies the defect. Instead the sensory loss must be discovered by a process of self-observation and inference. Discovery is easy for defects that create major functional disability, such as total blindness. Hence unawareness of total blindness occurs only in association with severe intellectual impairment, precluding the required self-observation and inference. In contrast, hemianopsia is difficult to discover because several mechanisms automatically compensate the defect effectively. Thus unawareness of hemianopsia is common, even in intellectually normal individuals. Insensate fields are often the source of suggested (false) percepts, because no information from such a field specifies the absence of a sensory stimulus. The most powerful source of suggestion is sensory activity in uninvolved portions of the affected sensory field. Thus hemianopsics may perceive complete geometric forms when only incomplete forms are shown and the missing portion falls in the hemianopsic fields. Such perceptual completion also occurs in hemianesthetic hemiplegics, creating the illusion that there are normally functioning limbs on the affected side. This perceptual completion increases the difficulty of discovery of hemianesthetic hemiplegia, but the disability is still sufficiently obvious that some additional cognitive impairment is invariably present in patients with lasting unawareness of hemiplegia. Phantom limb after amputation is the product of perceptual completion without associated cognitive impairment. The patient with phantom limb is thus aware of the illusory quality of his phantom. Some insight into the neural basis of perceptual completion and of unawareness of sensory loss may derive from considering sensory systems and associative cortex as parallel-distributed processing mechanisms. 相似文献

Verb processing during sentence comprehension in aphasia 总被引:6,自引:3,他引:3
This study examines verb processing during on-line sentence comprehension in aphasia. We describe two experiments that explore whether a group of Broca's aphasics, who were agrammatic in comprehension as well as speech, a group of fluent aphasics, and a group of normal controls are sensitive to the argument structure arrangements of verbs. Subjects had to perform a complex secondary task both in the immediate vicinity of the verb and also at a point well past the verb while listening to sentences for meaning. Reaction times to this secondary task show that both normal controls and agrammatic Broca's aphasic subjects activate multiple argument structure possibilities for a verb in the vicinity of the verb, yet at a point downstream from the verb such effects disappear. These data suggest that the problems agrammatic subjects show with verbs in sentence comprehension, and the general lexical access deficit also recently claimed to be part of the agrammatics' problem, may not extend to the real-time processing of verbs and their arguments. Fluent aphasic subjects, on the other hand, do not show sensitivity to the argument structure properties of verbs, suggesting that these patients may have a semantic-like sentence processing deficit. 相似文献

This paper describes a Geriatric Reinforcer Survey (GRS) which expands upon a previous Reinforcement Survey Schedule (RSS) developed by Cautela and Kastenbaum (1967). The GRS, an instrument designed to quickly assess reinforcer preference in geriatric populations, has two formats, one for individuals over 65 years of age who are still able to comprehend and write, and one designed to be filled out by relatives and staff familiar with an individual over 65 years of age who can no longer comprehend or write well. Reinforcer preference was determined by giving the GRS to a total of 107 geriatric persons in both home and institutional settings. Test-retest reliability was assessed on a subsample of 71 individuals over a 10-14-day period and was found to be rs = 0.608, p <0.01 using the Spearman Rank-Order Correlation Coefficient. This indicated that the GRS had reasonable test-retest reliability. The validity of having a relative or familiar staff person fill out the GRS for a specific individual was also tested. Results of 43 administrations of the GRS to relatives of a geriatric person, using the Spearman Rank-Order Correlation Coefficient, showed a correlation of rs = 0.488, p <0.01 when the responses of that person were compared to those of the individual. Results of 17 administrations of the GRS to staff familiar with a particular patient were rs = 0.436, p < 0.05 when compared to responses made by the individual. This indicates that the GRS might be useful in structuring interventions for individuals who are incapacitated, and groups of geriatric persons. The GRS also has the potential to be a valuable research tool. 相似文献
