Perspective change within a single environment is a slow and effortful process. However, little research has addressed perspective change across multiple environments. Using a task-set switching paradigm, subjects judged spatial relationships between target locations from differing perspectives. Response times were longer when successive trials probed different perspectives. However, this cost was greater when perspective was changed within a single environment compared to when it was changed across two environments. This result indicates that the processing of perspective change, and perhaps general spatial reasoning, differs in these two cases. Implications for theories of perspective change and environmental knowledge are discussed. 相似文献

The nosology of chronic depression in Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV, American Psychiatric Association, 1994) is highly complex and requires clinicians to differentiate among several chronic course subtypes. This study replicates an earlier investigation (J. McCullough et al., 2000; see record 2000-05424-007) that found few differences among Diagnostic and Statistical Manual of Mental Disorders (3rd ed. rev.; DSM-III-R; American Psychiatric Association, 1987) categories of chronic depression. In the present study, 681 outpatients with chronic major depression, double depression, recurrent major depression without full interepisode recovery, and chronic major depression superimposed on antecedent dysthymia were compared. Few differences were observed on a broad range of demographic, clinical, psychosocial, family history, and treatment response variables. The authors suggest that chronic depression should be viewed as a single, broad condition that can assume a variety of clinical course configurations. 相似文献

The purpose of this study was to assess the psychometric properties of the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD), the first clinician-administered scale for the assessment of change in DSM-IV borderline psychopathology. The questions for the measure were adapted from the BPD module of the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV) to reflect a 1-week time frame and each of the nine criteria for BPD is rated on a five-point anchored rating scale of 0 to 4, yielding a total score of 0 to 36. Two diagnostic interviews that assess the presence of BPD were administered to 200 nonpsychotic patients: the BPD module of the DIPD-IV and the Revised Diagnostic Interview for Borderlines (DIB-R). The ZAN-BPD was also administered, blind to diagnostic information. In addition, each patient filled out a self-report measure of general psychopathology that is often used in borderline treatment studies, the Symptom Checklist 90 (SCL-90). The convergent validity of the ZAN-BPD and relevant scales of the SCL-90 and the DIB-R was assessed and found to be highly significant. The discriminant validity of the various scores of the ZAN-BPD was also found to be highly significant, easily discriminating the 139 patients who met the DSM-IV criteria for BPD from the 61 patients who did not. In addition, internal consistency of the ZAN-BPD was found to be high (Cronbach's alpha=0.85). The interrater reliability of the ZAN-BPD was assessed using 32 conjoint interviews, while same day test-retest reliability was assessed in a separate sample of 40 patients. All reliability raters were blind to all previously collected information concerning each subject. All intraclass correlations were in the good to excellent range. Finally, the sensitivity of the ZAN-BPD to change was assessed using a third sample of 41 patients who were reinterviewed by a blind rater 7 to 10 days after the ZAN-BPD was first administered. The SCL-90 was also readministered at this time. The correlations between difference scores of the ZAN-BPD and difference scores of the SCL-90 were found to be significant, indicating that the ZAN-BPD measures change in a clinically meaningful manner. Taken together, the results of this study suggest that the ZAN-BPD is a promising clinician-administered scale for the assessment of change in borderline psychopathology over time. 相似文献

Borderline personality disorder (BPD) is a common psychiatric disorder that is often overlooked in treatment settings. This report describes the validation of a new self-report screening measure for DSM-IV BPD--the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD). Two hundred subjects with treatment histories whose ages ranged from 18 to 59 filled out the MSI-BPD. Each subject was then interviewed, blind to MSI-BPD results, with the BPD module of the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV; Zanarini, Frankenburg, Sickel, & Yong, 1996). Of these 200 subjects, 139 (69.5%) met DSM-IV criteria for BPD as assessed by the BPD module of the DIPD-IV and the remaining 61 subjects (30.5%) did not. Using logistic regression analyses, an MSI-BPD cutoff of 7 or more of the measure's 10 items was judged to be the best cutoff. This was so because it yielded both good sensitivity (.81; percentage of correctly identified cases) and specificity (.85; percentage of correctly identified noncases) for the diagnosis of DSM-IV BPD. For younger subjects, diagnostic efficiency was even greater. For example, sensitivity was .90 and specificity was .93 at a cutoff of 7 for the 63 subjects who were 25 years old or younger. The results of this study suggest that the MSI-BPD may be a useful screening instrument for the presence of DSM-IV borderline personality disorder. 相似文献

On an automated task, humans selected the larger of two sets of items, each created through the one-by-one addition of items. Participants repeated the alphabet out loud during trials so that they could not count the items. This manipulation disrupted counting without producing major effects on other cognitive capacities such as memory or attention, and performance of this experimental group was poorer than that of participants who counted the items. In Experiment 2, the size of individual items was varied, and performance remained stable when the larger numerical set contained a smaller total amount than the smaller numerical set (i.e., participants used numerical rather than nonnumerical quantity cues in making judgements). In Experiment 3, reports of the number of items in a single set showed scalar variability as accuracy decreased, and variability in responses increased with increases in true set size. These data indicate a mechanism for the approximate representation of numerosity in adult humans that might be shared with nonhuman animals. 相似文献

The McLean Study of Adult Development (MSAD) began 12 years ago. It is the first NIMH-funded prospective study of the course and outcome of borderline personality disorder (BPD). After careful analysis of the first six years of follow-up, 5 main findings concerning the symptomatic and psychosocial course of BPD have emerged from this study. The first finding is that remissions are far more common than previously recognized (about 74%). The second is that these remissions are quite stable and thus, recurrences are quite rare (about 6%). The third finding is that completed suicides are far more rare than anticipated (about 4% vs. 10%). The fourth finding is that a "complex" model of borderline psychopathology best describes BPD. In this model, some symptoms resolve relatively quickly, are the best markers for the disorder, and are often the immediate reason for needing costly forms of treatment, such as psychiatric hospitalizations. We termed these symptoms (e.g., self-mutilation, help-seeking suicide threats or attempts) acute symptoms. Other symptoms resolve more slowly, are not specific to BPD, and are closely associated with ongoing psychosocial impairment. We termed such symptoms (e.g., chronic feelings of intense anger, profound abandonment concerns) temperamental symptoms. Fifth, it was also found that borderline patients were improving psychosocially over time, particularly remitted borderline patients; psychosocial functioning of remitted patients continued to improve as time progressed, suggesting that they were somewhat belatedly achieving the milestones of young adulthood and not simply returning to a prodromal level of functioning. Taken together, these results suggest that the prognosis for BPD is better than previously recognized. 相似文献

In everyday life we accomplish tasks that require the storage and access of mental representations of different environments that we are not currently perceiving. Past research has suggested that environments are encoded by a series of independent representations that are organized in memory. Three experiments tested this idea further by asking whether multiple representations of environments can be accessed simultaneously. Using a cued task-set switching paradigm, subjects judged spatial relationships between target locations in two familiar environments. Response times were longer when successive trials probed different environments, an effect not due to switching between semantic categories or semantic priming, suggesting that representations of environments are accessed sequentially. Implications for various hypotheses concerning the properties of environmental representations are discussed. 相似文献

I argue that, for all we know, there are perfectly ordinary actual entities that are temporal in the usual sense and yet never present, past, or future. This epistemic fact requires us to modify the theses of presentism and eternalism. More importantly, it generates three new and quite serious objections to presentism, which I formulate and partially evaluate in this paper. 相似文献
