Receiving instrumental support at work: when help is not welcome 总被引:4,自引:0,他引:4
Deelstra JT Peeters MC Schaufeli WB Stroebe W Zijlstra FR van Doornen LP 《The Journal of applied psychology》2003,88(2):324-331
Although the role of social support in promoting employees' health and well-being has been studied extensively, the evidence is inconsistent, sometimes even suggesting that social support might have negative effects. The authors examined some psychological processes that might explain such effects. On the basis of the threat-to-self-esteem model, the authors tested the hypothesis that receiving imposed support elicits negative reactions, which are moderated by someone's need for support. The authors distinguished 3 different reactions: (a) self-related, (b) interaction-related, and (c) physiological. The results of an experiment with 48 temporary administrative workers generally confirmed the hypothesis. Imposed support elicited negative reactions, except when there was an unsolvable problem, but even then the effect of imposed support was not positive but neutral. 相似文献

A hypothetical evolutionary scenario is offered meant to account for the emergence of mental selves. According to the scenario, mental selves are constructed to solve a source-attribution problem. They emerge when internally generated mental contents (e.g., thoughts and goals) are treated like messages arising from external personal sources. As a result, mental contents becomes attributed to the self as an internal personal source. According to this view, subjectivity is construed outward-in, that is, one's own mental self is derived from, and is secondary to, the mental selves perceived in others. The social construction of subjectivity and selfhood relies on, and is maintained in, various discourses on subjectivity. 相似文献

Zusammenfassung 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.Herrn Prof. Dr. Ernst Richard Petzold zum 65. Geburtstag gewidmet. 相似文献

The role of sun compass orientation in spatial memory of Clark’s nutcrackers, Nucifraga columbiana, and pinyon jays, Gymnorhinus cyanocephalus, was studied in a series of cache recovery experiments. Birds were tested in an octagonal outdoor aviary with sand-filled
cups inserted in the floor. For caching, only 12 such cups in a 90° sector were available, while for recovery 4–7 days later
all 48 cups in the entire aviary were open. In control tests, the birds concentrated their search activity in the sector where
they had cached. When their internal clock was shifted 6 h between caching and recovery, pinyon jays shifted their search
activity to the 90° adjacent sector, as predicted if the sun compass was used. Clark’s nutcrackers did not respond to the
first clock-shift; however, they, too, shifted their search activity after a second clock-shift back to normal. This suggests
that the sun compass is a component of spatial memory in both species. Clark’s nutcrackers, however, seem to rely on their
sun compass to a lesser degree than pinyon jays or the previously studied scrub jays. A comparison of the findings indicates
that the role of the sun in spatial memory might reflect differences in habitat and ecology of the three corvid species.

Alzheimer's disease (AD) is accompanied by prominent behavioural disturbances. They cause significant distress for both caregivers and patients and can play a major role in the decision to institutionalise AD patients. Recent evidence suggests that cholinergic deficiencies not only contribute to the memory and cognitive abnormalities of AD but are also responsible for some behavioural abnormalities seen over the course of the disease. In this study we assessed the ability of rivastigmine, a pseudo-irreversible cholinesterase inhibitor, to improve behavioural and psychopathologic symptoms in AD. The analysis included 34 patients present in the Germanarm of the international study B303 who received and completed long-term treatment with rivastigmine in the open-label study B305. Assessments of behaviour and psychopathological symptoms were performed using the behavioural component of the Clinicians Interview Based Impression of Change Plus (CIBIC-Plus). Results show that long-term treatment with rivastigmine can slow the progression of behavioural and psychopathological symptoms of AD. Behavioural symptoms showing stabilisation included aggressiveness, activity disturbances, hallucinations and paranoid features. Results also suggest that patients treated earlier with rivastigmine may attain a greater benefit compared with patients whose treatment is delayed 6 months. Further studies examining the effects of rivastigmine on behavioural disturbances in AD are therefore warranted. 相似文献

Contrasting Cortical Activity Associated with Category Memory and Recognition Memory 总被引:5,自引:1,他引:4 下载免费PDF全文

We collected functional neuroimaging data while volunteers performed similar categorization and recognition memory tasks. In the categorization task, volunteers first studied a series of 40 dot patterns that were distortions of a nonstudied prototype dot pattern. After a delay, while fMRI data were collected, they categorized 72 novel dot patterns according to whether or not they belonged to the previously studied category. In the recognition task, volunteers first studied five dot patterns eight times each. After a delay, while fMRI data were collected, they judged whether each of 72 dot patterns had been studied earlier. We found strikingly different patterns of brain activity in visual processing areas for the two tasks. During the categorization task, the familiar stimuli were associated with decreased activity in posterior occipital cortex, whereas during the recognition task, the familiar stimuli were associated with increased activity in this area. The findings indicate that these two types of memory have contrasting effects on early visual processing and reinforce the view that declarative and nondeclarative memory operate independently. 相似文献

This paper applies a general theory of why religious movements succeed or fail to explain the meteoric rise of Christian Science, and to explain why the movement began an equally precipitous decline and may soon simply disappear. The analysis is based on quantitative data, on field work and on a variety of historical documents. The fall of Christian Science has many aspects, but particular emphasis is given to inadequate fertility, ineffective socialization, compromises in distinctiveness, a decline in the relative effectiveness of its placebo effects and to the greatly increased occupational opportunities for women. 相似文献
