In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide. 相似文献

Observing the transformation of experience into memory 总被引:16,自引:0,他引:16
The ability to remember one's past depends on neural processing set in motion at the moment each event is experienced. Memory formation can be observed by segregating neural responses according to whether or not each event is recalled or recognized on a subsequent memory test. Subsequent memory analyses have been performed with various neural measures, including brain potentials extracted from intracranial and extracranial electroencephalographic recordings, and hemodynamic responses from functional magnetic resonance imaging. Neural responses can predict which events, and which aspects of those events, will be subsequently remembered or forgotten, thereby elucidating the neurocognitive processes that establish durable episodic memories. 相似文献

John Abercrombie (1780-1844) was considered the most eminent Scottish physician of his time. In his Pathological and Practical Researches on the Diseases of the Brain and Spinal Cord (1836, Edinburgh: John Carfrae and Son, 3rd ed.) he described the cases of 140 patients with cerebral disorders, 48 of whom suffered from language disturbances. Despite the overwhelming clinical and neuropathological evidence of a close association between language disorder and right-sided hemiparesis or diseases of the left hemisphere, and in spite of his great interest in language disorders, he made no attempt to localize the aphasic syndrome to a specific brain area. 相似文献

Organizational Politics and Work Identity as Predictors of Organizational Commitment 总被引:1,自引:0,他引:1
L. A. Witt Anthony L. Patti William L. Farmer 《Journal of applied social psychology》2002,32(3):486-499
Building on the organizational-politics (Kaemar & Baron, 1999) and social-identity (Hogg & Terry, 2000) literatures, we examined the moderating effect of work identity on the organizational-politics/organizational-commitment relationship. Data collected from 500 employees of a data-reporting organization and 943 employees of a customer-service organization indicate that employees who identified primarily with their occupations were less affected by the level of perceived politics in the organization in the consideration of their commitment than were employees who identified primarily with their employing organizations or one of its units. Implications for research and management practice are discussed. 相似文献

Fifty‐eight outpatients with major depression completed the NEO Personality Inventory at intake (time 1) and after up to three months of anti‐depressant treatment (time 2). Within this group, 26 patients met additional Research Diagnostic Criteria for chronic minor depression. Repeated‐measures analyses revealed significant decreases in Neuroticism scores, and significant increases in Extraversion and Conscientiousness scores, from time 1 to time 2 for both patient groups. In addition, despite similar symptom severity at time 2, the patients with major depression+chronic minor depression scored significantly higher on the Angry Hostility facet of Neuroticism and significantly lower on Agreeableness than those with major depression alone. We suggest from these findings that Angry Hostility and low Agreeableness may represent a trait vulnerability in individuals with chronic minor depression that persists even following remission of the major depressive state, and that this may help to explain their high rates of relapse and recurrence.

The relationship among parasomnias, sleep-related violence (SRV), and psychosis has neither been reported nor studied. The authors introduce the phenomenon of psychotic dream-related aggression (PDRA) and, through a review of the research on manifest dreams, the continuity of thinking across the sleep–wake cycle, and SRV, argue for its inclusion alongside the parasomnias of DSM-IV. Five cases are presented that illustrate this phenomenon, usually a male diagnosed with paranoid schizophrenia whose violent act toward another was closely associated with the manifest content of his nocturnal dreams and his inability to test reality. Differential diagnostic criteria are proposed to separate PDRA from other parasomnias that may be related to violence. Treatment and forensic implications are discussed. 相似文献

A number of factors influence the outcomes of computer skills training and the likelihood of successful transfer. The first empirical test of a conceptual model of training transfer sought to explain how trainees' perceptions of various in-training transfer-enhancing activities such as overlearning, fidelity, stimulus variability, principles-meaningfulness, self-management activities, relapse prevention, and goal setting would predict the self-efficacy and implementation intentions (rather than actual transfer outcomes) of computer skills trainees. As expected, posttraining self-efficacy and transfer enhancing activities both predicted transfer implementation intentions. Pretraining self-efficacy also significantly predicted posttraining self-efficacy, trainees' level of learning during training and transfer enhancing activities, providing support for the conceptual model of training transfer. 相似文献

Die psychische Komorbidität internistischer Patienten im Sinne einer ICD-Diagnose des Kapitels F beträgt mehr als 35%: Neurotische, besonders somatoforme, Schmerz-, affektive Störungen und Suchterkrankungen sind häufig. Die Liegedauer ist bei psychischer Komorbidität deutlich erhöht. Es benötigen 5% der internistischen Patienten ein psychosomatisches Konsil. Neue, komplexe Behandlungsstrategien, wie Transplantationen, Kardioverter-Defibrillatoren, Medikamentenpumpen, erfordern häufig spezifische psychosoziale Interventionen. Ältere Patienten haben Erkrankungen, die zunehmend chronifizieren und komplexer werden. Damit werden Lebensqualität und psychische Komorbidität zu zentralen Outcomevariablen der Volkskrankheiten. Das zweite große Aufgabenfeld internistischer Psychosomatik ist die Untersuchung und die Behandlung psychosomatischer Patienten im engeren Sinne (Essstörungen, Schmerz- und somatoforme Störungen), weil internistische Diagnostik und Therapie erforderlich oder die Motivation der Patienten primär somatisch ist. Organisationsmodelle reichen von Konsil-/Liaisondiensten bis zu integrierten psychosomatischen Abteilungen oder Fachabteilungen an Allgemeinkrankenhäusern. Aussichtsreiche Forschungsstrategien werden neben der Erforschung psychosomatischer Mechanismen in der Entwicklung pragmatischer Behandlungsprogramme, ihrer Überprüfung in klinischen Studien und der Versorgungsforschung gesehen. Darüber hinaus sollte eine Intensivierung nationaler und internationaler Forschungsnetze erfolgen, wenn immer möglich unter Beteiligung anderer Disziplinen, um auch im Bereich der Forschung konkurrenzfähig zu bleiben. 相似文献
