Humphrey and Dahlstrom (1995) presented a study on the comparability of MMPI/MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles in which they concluded that "the bases for clinical interpretation derived from the MMPI and MMPI-2 profiles were sufficiently at variance to require different conclusions" [sic] (p. 2). In this brief critique, we identify procedural and data-analytical deficiencies that invalidate Humphrey and Dahlstrom's argument. Their blanket recommendation based on this argument, namely, that clinicians routinely plot both MMPI and MMPI-2 profiles, is unwarranted. 相似文献

This study provides preliminary tests of two hypotheses: (1) Anxiety-disordered children show an attentional bias toward emotionally threatening stimuli, and (2) normal controls show an attentional bias away from emotionally threatening stimuli. Twelve children, 9 to 14 years of age, with primary diagnoses of anxiety disorder were compared with 12 normal controls matched for age, gender, vocabulary level, and reading ability. Subjects completed a reaction time task that measured visual attention toward threatening versus neutral words. The anxious group showed the predicted attentional bias toward threat words. However, controls did not show the predicted bias away from threat words. These results are the first showing that biased attentional processing occurs among clinically anxious children. The potential role of such an attentional bias in childhood anxiety disorders and future direction for research are discussed.This research was supported by a Seed Grant and a Small Grant to the first author from The Ohio State University. Portions of this paper were presented at the 27th Annual Convention of the Association for the Advancement of Behavior Therapy, Atlanta, November 1993. Thanks are extended to the participants and all those who helped with the project. 相似文献

护士职业的人格特质研究 总被引:22,自引:1,他引:21
采用Y-G性格测验问卷,对临床护士和在读护生共390人,进行了心理测评,展开了护士职业的人格特质研究。研究结果表明:优秀护士群体的性格类型和某些人格特质显著地优于一般护士群体;优秀护士与一般护士间所显现出显著差异的人格特质,对于护士角色人格的构成具有决定性影响;Y-G性格测验的A型性格类型评定对于护士职业的心理选拔显现特异性趋势;整个测评研究结果,基本支持"护士个体人格特质与角色人格特质的匹配模式"等理论假设. 相似文献

Strong misalignment effects are found in three-dimensional (3-D) versions of Poggendorff displays viewed binocularly. The components of the standard 2-D Poggendorff figure—the parallels and the oblique segments—were presented in 3-D depth as a flat rectangular object with occluding edges and an oblique line situated behind the object. Three experiments investigated the misalignment effects under three different observation instructions: Subjects were told to look at the oblique (Experiment 1), at the rectangle (Experiment 2), or at the background (Experiment 3). Experiments 1 and 2 examined the effects on judgments of alignment of varying the distance in depth that separates the oblique from the rectangle. Experiment 3 examined the effects of varying the distance between the fixated background and the 3-D Poggendorff figure. Both standard and reversed misalignment effects were obtained. When the viewing condition produces crossed disparity for the oblique, perceived misalignment occurs in the usual Poggendorff direction, but it is reversed with uncrossed disparity. Moreover, the amount of misalignment is related to the amount of disparity, and it can be much stronger than is usual in the 2-D versions of the Poggendorff. The misalignment effects can be explained by binocular integration to produce a single cyclopean image. 相似文献

The spiritual journey of a Buddhist devotee is a continual exploration of the truth of interdependence which Siddhartha Gautama
realized to become the Buddha, “the Enlightened One.” On the morning of the enlightenment, the Buddha apprehended the truth
that all things and all beings are interconnected and mutually dependent in time and space. One measure of the spiritual maturity
of the Buddhist devotee is his or her appreciation for the profound responsibilities and gratitude we share for all things.
To illustrate the significance of interdependence in our lives, the author turns to the wisdom contained inVital Involvement in Old Age by Erik and Joan Erikson and Helen Q. Kivnick. 相似文献

Abstract— Infants' auditory detection thresholds are higher than adult thresh olds. Since adults listen selectively for an expected test tone frequency, and selective listening improves their detection performance, one hypothesis about why infant thresholds are high is that infants do not listen selectively. This hypothesis was tested by obtaining listening bands from adults and from 7- to 9-month-old infants. The results replicate earlier findings that adults listen selectively but indicate that infants do not. Lack of selective listening likely contributes to infants' high thresholds. Further, the finding that infants and adults have different listening strategies has implications for infants' auditory perception in general. 相似文献

An experiment was conducted to relate individual components of the event-related brain potential to specific stages of information processing in a two-choice reaction time (RT) task in a group of undergraduate students. Specifically, the latency of the P300 component and the lateralized readiness potential (LRP) were studied as a function of variations in stimulus degradation and response complexity. It was hypothesized that degrading the stimulus would delay the P300 and LRP to the same extent as RT, and that increasing response complexity would affect RT but not P300 latency. The extant literature did not permit any hypothesis regarding the effect of response complexity on LRP latency. The two task variables were found to have additive effects on RT. As predicted, variations in stimulus degradation influenced the latencies of both components, whereas alterations in response complexity had no effect on P300 latency. A significant new finding was that the onset latency of the LRP remained unchanged across levels of response complexity. The overall pattern of results supports the notion of temporal selectivity of stage manipulations that is derived from discrete stage models of human information processing. Furthermore, these results refine the functional interpretation of the LRP by indicating that within the conceptual framework of a stage model the processes this component indexes succeed the start of response choice but precede the start of motor programming. 相似文献

When lithium serum levels were within the (human) therapeutic range, young and old adult male and female rats (housed singly or in groups) all displayed faster limbic seizure onset times in response to a muscarinic cholinergic agonist (pilocarpine 20 mg/kg) if a single systemic dosage of chlorpromazine was injected 24 hours previously. The effect was comparable to injecting an additional 10 mg/kg of pilocarpine. These results strongly suggest that cholinergic rebound from chlorpromazine administrations during lithium treatment could facilitate subclinical electrical lability and very localized neuronal necrosis within the limbic system of clinical patients, resulting in normalization of psychiatric symptoms. 相似文献
