The menstrual cycle has been reported to alter pain perception but the patterns differ among studies. It has been reported that estrogens may influence somatic sensory processes. The present aim was to investigate whether the perception of pain varies by phases of the menstrual cycle. 20 women with chronic low pain volunteered to participate and were asked to rate their pain each day during three successive menstrual cycles. The menstrual cycle was divided into four and five phases to be able to compare results. Analysis showed there were phase differences in pain ratings during the menstrual cycle. Regardless of whether the menstrual cycle was divided into four or five phases, women rated pain significantly higher in the menstrual and premenstrual phases than in the midmenstrual and ovulatory phases. This is consistent with other studies showing less pain sensitivity during phases of the menstrual cycle associated with high estrogen. Women with high pain frequency reported more frequently a passive coping style and catastrophizing thoughts. 相似文献

This article presents some empirical findings concerning memory for violent real-life events. Witnesses who had observed a bank robbery, either as a victim or a bystander, were interviewed and studied with respect to emotional reactions and memory for detailed information about the robbery. The consistency of the witnesses' accounts was measured by a comparison of information gathered in the police reports and the recollection given in a research interview. Overall, the results showed relatively high accuracy rates after an extended time interval with respect to specific details about the robbery (e. g. action, weapon, clothing). For some details, however, the witnesses showed a rather low performance (e. g. colour of eyes and hair, and details of the surrounding circumstances). There was no significant relationship between rated degree of emotion and the number of details remembered. These findings contradict the negative relationship between stress and memory that many experts on eyewitness testimony believe in (Kassin, Ellsworth, and Smith, 1989). Points of commonality in findings from real-life studies and simulation studies are discussed. 相似文献

Cognitive outcome after preterm birth is heterogeneous, and group level analyses may disguise individual variability in development. Using a person-oriented approach, this study investigated individual cognitive patterns and developmental trajectories from preschool age to late adolescence. As part of a prospective longitudinal study, 118 adolescents born preterm, with a birth weight < 1,500 g, participated in neuropsychological assessments at age 5½ years and at 18 years. At each age, four cognitive indices, two tapping general ability and two tapping executive functions, were formed to reflect each individual’s cognitive profile. Cluster analyses were performed at each age separately, and individual movements between clusters across time were investigated. At both 5½ and 18 years, six distinct, and similar, cognitive patterns were identified. Executive functions were a weakness for some but not all subgroups, and verbal ability was a strength primarily among those whose overall performance fell within the normal range. Overall, cognitive ability at 5½ years was highly predictive of ability at age 18. Those who performed at low levels at 5½ years did not catch up but rather deteriorated in relative performance. Over half of the individuals who performed above the norm at 5½ years improved their relative performance by age 18. Among those performing around the norm at 5½ years, half improved their relative performance over time, whereas the other half faced increased problems, indicating a need for further developmental monitoring. Perinatal factors were not conclusively related to outcome, stressing the need for cognitive follow-up assessment of the preterm-born child before school entry. 相似文献

As a social construct, our approach to work with severely disturbed psychiatric patients in crisis, termed Open Dialogue (OD), begins treatment within 24 hours of referral and includes the family and social network of the patient in discussions of all issues throughout treatment. Treatment is adapted to the specific and varying needs of patients and takes place at home, if possible. Psychological continuity and trust are emphasized by constructing integrated teams that include both inpatient and outpatient staff who focus on generating dialogue with the family and patients instead rapid removal of psychotic symptoms. The main principles are described, and a case is analyzed to illustrate these. 相似文献

Previous research in social psychology has brought about significant changes in attitudes and behaviour by merely asking respondents to imagine, or reflect, on a phenomenon and arrive at their own conclusions. To test the potential of such interventions in the traffic safety area, an experiment comprising 353 young men 18–23 years old with a driver’s licence was conducted. Two experimental groups were induced to imagine a severe accident scenario and to visualize their feelings and the consequences on their future lives. A control group was interviewed about neutral issues. Attitudes towards risk-taking were measured post-intervention and at follow-up. The experimental groups showed more “ideal” attitudes than the control group post-intervention. At follow-up the attitudes of the experimental group remained unchanged, whereas the control group had changed towards more “ideal” attitudes. Self-reported risk-taking behaviour was measured pre-intervention and at follow-up. At follow-up all groups reported significantly less risk-taking behaviour than at pre-intervention. It is suggested that answering the questionnaires increased mental elaboration concerning risky driving, and it is concluded that interventions that unobtrusively make drivers reflect on their driving should be explored further as a means to promote traffic safety. 相似文献

In two experiments, brightness enhancement of the illusory surface in the Kanizsa square was investigated by means of a brightness matching procedure. The results show that specific properties of the inducing elements such as size, spacing, and luminance have effects on the matching threshold that are similar to those previously obtained in experiments on simultaneous con trast. The data from a third experiment demonstrate that increment thresholds measured within the Kanizsa square are elevated when the target is flashed on a position close to the inducing elements. The thresholds decrease considerably in the center of both test and control figures (representing or not representing an illusory square). These observations suggest that low-level mechanisms are likely to explain local brightness differences within the configurations but not global figure brightness. In other words, local contrast seems to generate brightness information that “sketches out” surfaces at their surrounds but does not “fill” them “in.” 相似文献

Psychological scaling methods can be applied and can bring substantial knowledge to bear upon problems within the realm of environmental hygiene. Methodological issues related to the possibility of obtaining calibrated scales of perceptual variables such as discomfort, annoyance, and unpleasant odors are critical when the scale values are to be entered into a physical pollution index or a perceived environmental quality index, both being applied in the form of norms or recommendations. The level of measurement (ordinal, interval, or ratio scale) is related to the question of calibration of scales. From a practical point of view, the effects of observer-environment dependence are important to disguise in the scale values. Problems having to do with calibration of scales and with application of knowledge about perceptual processes to the scales are being explored in ongoing research projects. These include the measurement of temperature discomfort in different climates and the measurement of annoyance in areas with different noise exposures. Attempts have been made to solve an odorous air pollution problem with psychological measurements. 相似文献

In the two experiments, the use of a psychophysical procedure of brightness/darkness cancellation shed light on interactions between spatial arrangement and figure-ground contrast in the perceptual filling in of achromatic and colored surfaces. Achromatic and chromatic Kanizsa squares with varying contrast, contrast polarity, and inducer spacing were used to test how these factors interact in the perceptual filling in of surface brightness or darkness. The results suggest that the neuronal processing of surfaces with apparent contrast, leading to figure-ground segregation (i.e., perceptual organization), is governed by mechanisms that integrate both luminance contrast and spatial information carried by the inducing stimuli, while discarding information on contrast polarity or color. The findings are discussed in relation to earlier observations on brightness assimilation and contrast. They support theories of nonantagonistic neural mechanisms suppressing local contrast or color signs in brightness-based figure-ground percepts. Such mechanisms might be necessary to cancel potentially conflicting polarities in geometrically complex visual stimuli so that perceptual filling in resulting in the most plausible representation of figure and ground can be achieved. 相似文献
