This study investigates the relationship of etiological factors to infant sleeping problems during the first year, and at follow‐up during the second year of life. The relevant factors for concurrent sleeping problems (in order of importance) were problematic maternal cognition concerning setting limits on the infant, fussy–difficult infant temperament, maternal anxiety–depression, ambivalent attachment, and certain maternal care‐giving behaviors involving the use of active physical comforting (cuddling to sleep, settling on sofa or in parental bed, and giving a feed). High initial levels of sleeping problems largely explained the continuity in infant sleeping problems over time. However, this continuity was significantly mediated by the influence of both problematic maternal cognition and infant temperament on the parental use of active physical comforting to settle infants to sleep. In addition, ambivalent attachment had a small but significant independent contribution to persistent problems. Regarding discontinuity in infant sleeping problems over time, infants who developed sleeping problems were those whose parents used high levels of active physical comforting, whereas those infants whose sleeping problems recovered were more likely to have mothers with low depression–anxiety. The significance of these results is discussed with respect to developmental models of infant sleeping problems, and the assessment and treatment of infant sleeping problems. ©2003 Michigan Association for Infant Mental Health. 相似文献

The use of photographs to augment media reports of kidnapping victims in Iraq has sparked debates over the effects of such images on the public and, ultimately, the politics surrounding the event. We considered the effects of such images in a sample of British university students during the 2004 kidnapping of British citizen Kenneth Bigley. Drawing on emotions theory, we examined the effects of graphic images on emotional reactions and attitudes towards negotiations. Half of the participants were exposed to photographs of the victim that had recently been published in a national newspaper. The other half were not shown any images. As predicted, the photographs increased fear reactions amongst participants compared to no photograph controls. Fear and sympathy, but not anger, predicted attitudes towards negotiation. The photographs used in this study thus indirectly increased participants' support for negotiating with and submitting to the demands of the captors. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

T he Health Belief Model (HBM; Rosenstock, 1966) is the most widely used psychological theory of health‐related behaviours but its applicability to non‐Western, especially Asian, populations has not been systematically studied. The main objective of the current study was to examine the effects of components of the HBM and dispositional optimism on preventive intention in two separate samples of 220 Hong Kong Chinese adults and 340 Hong Kong Chinese adolescents. Two HBM variables, benefits and barriers, were experimentally manipulated for an imaginary flu outbreak and a hypothetical vaccine. Optimism in the two samples was assessed using the Chinese revised Life Orientation Test (Lai et al., 1998). Participants indicated their intention to take the hypothetical vaccine after reading information for each of the treatment combinations defined by the two HBM variables. The order of the presentation of each of the six treatment conditions was counterbalanced. Results of ANOVA showed that the effects of the two HBM variables were similar in the two groups. Higher benefits and lower barriers were associated with stronger behavioural intention to take the vaccine. The two HBM variables interacted significantly in the adolescent but not the adult sample. Among the adolescents, the difference in intention scores between low and high barriers became larger when the benefits of taking the vaccine increased. In addition, optimism had significant effect on preventive intention only among the adolescents. These findings suggest that age may be an important factor moderating the effects of HBM components as well as optimism on preventive intention in Hong Kong Chinese. Implications of these findings to future research among Chinese were discussed. 相似文献

Rodent lesion studies have revealed the existence of two causally dissociable spatial memory systems, localized to the hippocampus and striatum that are preferentially sensitive to environmental boundaries and landmark objects, respectively. Here we test whether these two memory systems are causally dissociable in humans by examining boundary‐ and landmark‐based memory in typical and atypical development. Adults with Williams syndrome (WS)—a developmental disorder with known hippocampal abnormalities—and typical children and adults, performed a navigation task that involved learning locations relative to a boundary or a landmark object. We found that boundary‐based memory was severely impaired in WS compared to typically‐developing mental‐age matched (MA) children and chronological‐age matched (CA) adults, whereas landmark‐based memory was similar in all groups. Furthermore, landmark‐based memory matured earlier in typical development than boundary‐based memory, consistent with the idea that the WS cognitive phenotype arises from developmental arrest of late maturing cognitive systems. Together, these findings provide causal and developmental evidence for dissociable spatial memory systems in humans. 相似文献

In visual search of natural scenes, differentiation of briefly fixated but task-irrelevant distractor items from incidental memory is often comparable to explicit memorization. However, many characteristics of incidental memory remain unclear, including the capacity for its conscious retrieval. Here, we examined incidental memory for faces in either upright or inverted orientation using Rapid Serial Visual Presentation (RSVP). Subjects were instructed to detect a target face in a sequence of 8–15 faces cropped from natural scene photographs (Experiment 1). If the target face was identified within a brief time window, the subject proceeded to an incidental memory task. Here, subjects used incidental memory to discriminate between a probe face (a distractor in the RSVP stream) and a novel, foil face. In Experiment 2 we reduced scene-related semantic coherency by intermixing faces from multiple scenes and contrasted incidental memory with explicit memory, a condition where subjects actively memorized each face from the sequence without searching for a target. In both experiments, we measured objective performance (Type 1 AUC) and metacognitive accuracy (Type 2 AUC), revealing sustained and consciously accessible incidental memory for upright and inverted faces. In novel analyses of face categories, we examined whether accuracy or metacognitive judgments are affected by shared semantic features (i.e., similarity in gender, race, age). Similarity enhanced the accuracy of incidental memory discriminations but did not influence metacognition. We conclude that incidental memory is sustained and consciously accessible, is not reliant on scene contexts, and is not enhanced by explicit memorization. 相似文献

Thinking about Community Psychology primarily as a science may make it harder, rather than easier, to embrace certain aspects of the field to which we are deeply committed, but usually fall outside the conventional meaning of doing science. While community psychologists use (and expand) the tools of science, this is different than saying that Community Psychology is only, or even primarily, a science. The field is just as much social criticism as it is science. In order to further conversation about these matters, seven thoughts about why (thank God) community psychology is more than a science are offered, the most basic of which is that today the greatest danger to freedom is not in the union of church and state, but in the union of science and state.Based on a paper presented at a Symposium, A. Wandersman (Chair), Science and Community Psychology, Held at the 9th Biennial Meeting of the Society for Community Research and Action, June, 2003, Las Vegas, New Mexico. 相似文献

Growth of urban areas, the corresponding increased demand for utility services and the possibility of new types of utility
systems are overcrowding near surface underground space with urban utilities. Available subsurface space will continue to
diminish to the point where utilidors (utility tunnels) may become inevitable. Establishing future sustainable strategies
in urban underground engineering consists of the ability to lessen the use of traditional trenching. There is an increasing
interest in utility tunnels for urban areas as a sustainable technique to avoid congestion of the subsurface. One of the principal
advantages of utility tunnels is the substantially lower environmental impact compared with common trenches. Implementing
these underground facilities is retarded most by the initial cost and management procedures. The habitual procedure is to
meet problems as they arise in current practice. The moral imperative of sustainable strategies fails to confront the economic
and political conflicts of interest. Municipal engineers should act as a key enabler in urban underground sustainable development. 相似文献

A Norwegian version of the Penn State Worry Questionnaire (PSWQ) was administered to 304 undergraduate students together with the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI) and the Maudsley Obsessive Compulsive Inventory (MOCI). The PSWQ was also administered to a community sample comprising 879 subjects, together with the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI II) and the White Bear Suppression Inventory (WBSI). Structural equation modeling showed that a three-factor solution of the PSWQ gave the best goodness of fit. The Norwegian version of the PSWQ demonstrated adequate psychometric properties in terms of reliability and validity in both samples. Females scored higher than males on PSWQ. 相似文献

Little information exists on the contribution of psychological strengths to well-being in persons with post-traumatic stress disorder (PTSD). Data from other populations suggest that gratitude, defined as the positive experience of thankfulness for being the recipient of personal benefits, may have salutary effects on everyday functioning. We investigated whether dispositional gratitude predicted daily hedonic and eudaimonic well-being in combat veterans with and without PTSD. We also examined associations between daily gratitude and daily well-being across time. Veterans with PTSD, compared to those without PTSD, exhibited significantly lower dispositional gratitude; no differences were found on daily gratitude. Dispositional gratitude predicted greater daily positive affect, percentage of pleasant days over the assessment period, daily intrinsically motivating activity, and daily self-esteem over and above effects attributable to PTSD severity and dispositional negative and positive affect in the PTSD group but not the non-PTSD group. Daily gratitude was uniquely associated with each dimension of daily well-being in both groups. Although preliminary, these results provide support for the further investigation of gratitude in trauma survivors. 相似文献
