Organizational design is presented as a decision process, with specific structures seen as providing alternative choices. To illustrate this, the authors present the case of a major metropolitan hospital that used the process to coordinate service delivery (nursing care versus patient care) and service focus (product oriented versus function oriented). Through interviews with more than 40 hospital administrators and staff, the authors created a list of 20 attributes, and used simple multi-attribute utility analysis to generate six design alternatives. The decision makers unanimously chose one alternative, even though potential for significant conflict existed because of differing values and objectives. The authors find decision analytic techniques useful for both the problem formulation and for generating and evaluating structural alternatives, and conclude that in this case consensus was facilitated by the decision process used.  相似文献

Studies of the inverted-face effect typically use photos as stimuli. Inverting photos not only misorients the face but also reverses important shading and shadow cues. We decoupled the influence of spatial orientation and the direction of lighting in three experiments and found that the relation between these factors varied with the task given to observers. When the task required identification of faces (Experiments 1 and 3), the factors were additive, consistent with a strategy of mental rotation of the face prior to an interpretion of the shading cues. When faces were assigned to coarse categories (Experiments 2 and 3), these factors interacted, consistent with a more piecemeal approach to face processing. We propose that the identification of a specific individual depends on configurational information, which is preserved if the image of an inverted face is mentally rotated before the identification process is begun.  相似文献

The rise of language occurs simultaneously in the life of a very young child with the capacity to form self-identity. For this reason, specific characteristics of a person's subsequent use of language may facilitate recognition of factors that were significant to ego formation. Affective memories are laid down in this process and fixed for ego-management. Bower (1981) elegantly demonstrated how a whole nexus of affective memories can be elicited when a specific key association is activated. In two case illustrations, psychoanalytic treatment was facilitated by use of key verbal associations. In both cases, these associations proved to be inwardly permissible because they were based on forms linked to developmental levels rather than the content of what was being expressed.  相似文献

In spite of the high proportion of persons with a migration background in Germany, professional mental health care utilization by this population group still seems to be insufficient. This could be due to social as well as structural and individual barriers which impede the professional mental health care-seeking process. The heuristic Mental Health Action Process Approach (M-HAPA) model was developed in order to be able to empirically investigate the specific mechanism of action as well as the specific time of influence of these factors. An empirically supported model should possibly be able to justify targeted interventions. The M-HAPA model describes mental health care utilization behavior, combines the basic ideas of already existing models describing health behavior and health care utilization behavior as well as factors which are specifically relevant for the health care utilization behavior of persons with a migration background. This combination may serve as a basis for future research in the field of mental health care utilization behavior of persons with a migration background.  相似文献

A conceptual frame of reference called The River is presented for training of beginning psychotherapists. Using metaphors, trainees are taught specific tools (Equipment) and to identify salient features of the therapy process (Topography) by means of a series of metaphors for the process elements of timing and of level of intervention. Student therapist feedback indicated that this model facilitated learning of how much or little to do at given points in the therapeutic process, and that these metaphors appeared to transcend specific theoretical orientations.  相似文献

We explored the hypothesis that to perceive an event is to detect an invariant specific to the style of change and an invariant specific to the object undergoing the style of change-the reciprocal invariants of transformation and structure, respectively. Events were defined by seven geometric transformations that produced a variety of styles of change over different objects. In Experiment 1, we examined the generative and abstract aspects of transformational invariants. An event was presented as a sequence of static samples and examined in interpolation and extrapolation tasks. The transformational invariant proved sufficiently generative and abstract to specify a unique style of change. In Experiment 2, we found that types of change and types of objects interacted, which implies that certain styles of change are more compatible with certain object structures. In Experiment 3, we found that the structural invariant was reliably detectable but that the degree to which structural properties were preserved depended on the kind and amount of transformation applied. Taken together, the experiments provide support for the hypothesis that perceiving an event is detecting the two reciprocal invariants of transformation and structure that together specify the event.  相似文献

The latency to initiate a saccade (saccadic reaction time) to an eccentric target is reduced by extinguishing the fixation stimulus prior to the target onset. Various accounts have attributed this latency reduction (referred to as the gap effect) to facilitated sensory processing, oculomotor readiness, or attentional processes. Two experiments were performed to explore the relative contributions of these factors to the gap effect. Experiment 1 demonstrates that the reduction in saccadic reaction time (RT) produced by fixation point offset is additive with the effect of target luminance. Experiment 2 indicates that the gap effect is specific for saccades directed toward a peripheral target and does not influence saccades directed away from the target (i.e., antisaccades) or choice-manual RT. The results are consistent with an interpretation of the gap effect in terms of facilitated premotor processing in the superior colliculus.  相似文献

The concept of structural dissociation can provide useful information for increasingly complex applications of mentalizing in therapeutic settings; however, little integration of the two approaches has emerged. Grounded in the intricate case of a woman diagnosed with dissociative identity disorder, this case study integrates and applies the concepts of structural dissociation and mentalizing from an attachment perspective. Client history includes pervasive spiritual and sexual abuse, as well as extreme neglect throughout her development. The presenting problems, relevant history (including the profound impact of neglect), and the therapeutic models that guided treatment are described. Also presented are the specific therapeutic interventions that have facilitated and strengthened therapeutic alliances, levels of integration, and mentalizing capacity in this challenging but rewarding study of human resiliency.  相似文献

This study is concerned with assessing whether social marking, i.e. the correspondence between the cognitive solution of a task and the social relation expressed in the material, is a mechanism of cognitive progress which depends on specific forms of socio-cognitive conflict or on presence of familiar social relations in the material. In the first experiment 5-6-year-old non-conserver children were selected during a pre-test that comprised three spatial transformation tasks. During the test phase, 56 children worked on spatial transformation tasks with an adult partner in four socially marked conditions in which the correctness of the adult model varied. All subjects were individually post-tested on the same tasks with unmarked content. Results showed that, under the same marked conditions in the test phase, more progress took place, at the post-test phase, when subjects had interacted with an incorrect adult model than when they had interacted with a correct one. In the second experiment the hypothesis of an interaction between the nature of the material and the kind of social interaction was examined by means of a factorial design in which the factors were adult versus child partner and marked versus unmarked material. The procedures in the pre- and post-test phase were carried out in the same way as in Experiment I. In the test phase 61 non-conserver children interacted with partners who presented completely incorrect model. The results of post-test phase indicated that there was a main effect of social marking although findings of a condition in which children interact with another child on unmarked material also have shown a certain amount of progress. The findings are discussed with respect to the psycho-social model of cognitive development.  相似文献

In this study, we investigated whether the left and right hemispheres are differentially involved in causal inference generation. Participants read short inference-promoting texts that described either familiar or less-familiar scenarios. After each text, they performed a lexical decision on a letter string (which sometimes constituted an inference-related word) presented directly to the left or right hemisphere. Response-time results indicated that hemisphere of direct presentation interacted with type of inference scenario. When test stimuli were presented directly to the left hemisphere, lexical decisions were facilitated following familiar but not following less-familiar inference scenarios, whereas when test stimuli were presented directly to the right hemisphere, facilitation was observed in both familiar and less-familiar conditions. Thus, inferences may be generated in different ways depending on which of two dissociable neural subsystems underlies the activation of background information.  相似文献

We examined effects of a culture-general factor, pattern redundancy (number of repeated tones), on the discrimination of 5-tone melodies that differed in their adherence to Western tonal conventions. Experiment 1 evaluated the ability of 9-month-old infants to differentiate "standard" melodies from subtly altered "comparison" melodies. Greater redundancy of the standard melodies was associated with enhanced infant performance, but musical conventionality had no effect. Experiment 2 evaluated comparable abilities in 5-year-old children and musically untrained adults. Children's performance was enhanced by the redundancy of standard melodies, but the effect was greater in conventional than in unconventional contexts. The redundancy of standard melodies facilitated adults' performance in conventional but not in unconventional contexts. Thus, increasing musical exposure seems to attenuate the effects of culture-general factors such as pattern redundancy while amplifying the influence of culture-specific factors.  相似文献

This study demonstrates the use of structural equation modeling for investigating a hierarchical model of personality based on Loevinger's (1976) conceptualization. This model was constructed to have a multifactorial and hierarchical structure in which the ego development construct served as the source of covariation for specific personality constructs of impulse control, interpersonal style, conscious preoccupations, and cognitive style. This model and three other conceivable models were investigated to determine which structure best represented the relations among specific personality constructs and ego development. The specific personality constructs were identified by measures chosen from the available pool of measures that were compatible with Loevinger's conceptualization. The four conceivable models were fitted to sample data from 267 adult subjects using confirmatory factor analysis and were compared with indices of model fit and methods for comparison of nested models. Results suggested that the four specific personality constructs and ego development are part of the same process. Although a hierarchical structure appeared tenable for this process, the role of ego development perhaps is not as dominant as envisioned by Loevinger. These results must be considered tentative due to measurement limitations.  相似文献

In this study, independent samples from the same population responded to three simulated situations in which sex and other independent variables were manipulated. In the first two cases, discriminatory decisions against women managers by male respondents were clearly discerned. However, in the third case where sex as an independent variable interacted with developmental potential, the pattern of evaluative decisions changed. A high-potential female was treated as favourably as a high-potential male while the low-potential male received the lowest selection rate from the male respondents. While the finding is not altogether surprising in a meritocratic society like Singapore, the study points to the need to explore the interactive effects which sex bias may have with other attitudes in a specific social context.  相似文献

过去几十年中, 研究者基于脑区功能定位的思想对发展性阅读障碍的神经机制进行了大量的研究, 揭示出阅读障碍者在特定脑区的异常。近些年, 考虑到阅读加工过程的复杂性以及需要多脑区协同参与的特点, 越来越多的研究者从脑区连接的角度探讨阅读障碍的神经机制。结果发现阅读障碍者在阅读相关脑区间的白质结构连接和功能连接上均表现出异常, 这说明阅读技能受损和脑区连接异常之间存在着密切的联系。未来的研究还需进一步探讨脑区连接异常和特定脑区异常之间的关系, 以及结合基因、脑、行为和环境等多个因素探寻阅读障碍的发生机制。  相似文献

In this report, we examine tachistoscopic perception of lines in structured figures. Previous research has shown that perception of lines is facilitated when the lines occur as parts of coherent three-dimensional figures. Experiment 1 demonstrates that it is not necessary for the figure to be three-dimensional to obtain facilitation. Experiments 2 and 3 show that three-dimensionality is not sufficient either. What is important is that the target lines be structurally relevant to the figure. However, structural relevance of a target segment to the figure as perceived with unlimited viewing time is not perfectly correlated with perceptibility under tachistoscopic conditions; it appears that the targets which fall on the external contour of a figure may be facilitated even without a high degree of structural relevance. In view of this, we suggest a model in which perceivers use processing heuristics to direct processing to aspects of the input that are potentially important for determining the structure of the final figure, working primarily from the outside in.  相似文献

D-cycloserine (DCS) may facilitate fear extinction learning, but the behavioral consequences and mechanisms behind this effect are not well understood at present. In this paper, we re-analyze data from previously reported null result experiments and find that rats showing above-median extinction learning during DCS treatment benefited from the drug, whereas rats showing below-median (and in this case little) extinction learning did not. Two additional experiments found that DCS facilitated extinction learning when specifically combined with a moderate, but not a small, number of extinction trials. DCS thus facilitates extinction learning only if the behavioral procedure first engages the extinction learning process. The benefits of the drug, however, were specific to the context in which extinction was learned--i.e., DCS did not prevent or influence the renewal of fear observed when the extinguished cue was tested in the original conditioning context.  相似文献

Individuals' memory experiences typically covary with those of others' around them, and on average, an item is more likely to be familiar if a companion recommends it as such. Although it would be ideal if observers could use the external recommendations of others' as statistical priors during recognition decisions, it is currently unclear how or if they do so. Furthermore, understanding the sensitivity of recognition judgments to such external cues is critical for understanding memory conformity and eyewitness suggestibility phenomena. To address this we examined recognition accuracy and confidence following cues from an external source (e.g., "Likely Old") that forecast the likely status of upcoming memory probes. Three regularities emerged. First, hit and correct-rejection rates expectedly fell when participants were invalidly versus validly cued. Second, hit confidence was generally higher than correct-rejection confidence, regardless of cue validity. Finally, and most noteworthy, cue validity interacted with judgment confidence such that validity heavily influenced the confidence of correct rejections but had no discernible influence on the confidence of hits. Bootstrap-informed Monte Carlo simulation supported a dual process recognition model under which familiarity and recollection processes counteract to heavily dampen the influence of external cues on average reported confidence. A 3rd experiment tested this model using source memory. As predicted, because source memory is heavily governed by contextual recollection, cue validity again did not affect confidence, although as with recognition it clearly altered accuracy.  相似文献

In 3 experiments rats were preexposed to the landmarks that surround a Morris pool by being placed on a submerged platform within the pool. They were then required to escape from the pool by swimming to the platform, which was in a location that had not been used during preexposure. Preexposure facilitated subsequent escape from the pool, provided that the platform was not moved during preexposure and the relative position of the landmarks to each other remained constant throughout preexposure. In contrast, if during preexposure the platform was moved from session to session (Experiment 1), or the array of landmarks was altered unsystematically from trial to trial (Experiments 2 and 3), then subsequent learning to escape from the pool was disrupted. These findings suggest that the effects of preexposure to the landmarks in a Morris pool is determined by whether or not they are of relevance for identifying the location of the platform. When they are relevant, then subsequent learning is facilitated, but when they are irrelevant, then subsequent learning is disrupted.  相似文献
