How humans perform duration judgments with multisensory stimuli is an ongoing debate. Here, we investigated how sub-second duration judgments are achieved by asking participants to compare the duration of a continuous sound to the duration of an empty interval in which onset and offset were marked by signals of different modalities using all combinations of visual, auditory and tactile stimuli. The pattern of perceived durations across five stimulus durations (ranging from 100 ms to 900 ms) follows the Vierordt Law. Furthermore, intervals with a sound as onset (audio-visual, audio-tactile) are perceived longer than intervals with a sound as offset. No modality ordering effect is found for visualtactile intervals. To infer whether a single modality-independent or multiple modality-dependent time-keeping mechanisms exist we tested whether perceived duration follows a summative or a multiplicative distortion pattern by fitting a model to all modality combinations and durations. The results confirm that perceived duration depends on sensory latency (summative distortion). Instead, we did not find evidence for multiplicative distortions. The results of the model and the behavioural data support the concept of a single time-keeping mechanism that allows for judgments of durations marked by multisensory stimuli. 相似文献

A growing amount of evidence confirms the influence of reading and writing habits on visuospatial processing, although this phenomenon has been so far testified mainly as a lateralized shift of a single behavioral sign (e.g., line bisection), with lack of proof from pure right-to-left readers. The present study contributed to this issue by analyzing multiple attentional and motor indexes in monolingual Italian (i.e., reading from left-to-right), and monolingual (i.e., reading from right-to-left) and bilingual Israeli (i.e., reading from right-to-left in Hebrew but also from left-to-right in English) participants' visuospatial performance. Subjects were administered a computerized standard star cancellation task and a modified version in which English letters and words were replaced by Hebrew ones. Tasks were presented on a graphics tablet, allowing recording of both chronometric and spatial parameters (i.e., measured in (x, y) vector coordinates). Results showed that reading direction modulated the on-line visuomotor performance (i.e., left-to-right vs. right-to-left shifts) from the beginning (i.e., first mark) to the end of the task (i.e., spatial distribution of omissions and subjective epicenter). Additionally, the spatial bias observed in a computerized line bisection task was also related to the participants' habitual reading direction. Overall, the results favor the proposal of an Interactive Account of visuospatial asymmetries, according to which both cultural factors, such as the directional scanning associated with language processing, and biological factors, such as hemispheric specialization, modulate visuospatial processing. Results are discussed in light of recent behavioral and neuroanatomical findings. 相似文献

Asymmetric Perception of Gains versus Non‐losses and Losses versus Non‐gains: The Causal Role of Regulatory Focus 下载免费PDF全文
Recent studies show that, while losses loom larger than equivalent non‐gains, gains loom larger than equivalent non‐losses. This finding has been interpreted within the framework of regulatory focus theory. In this study, we highlight the importance of considering the motivational focus independently of the framing and the valence of outcome, thus exploring the causal effect of regulatory focus on the asymmetric perception of gains versus non‐losses and losses versus non‐gains. In two studies, we examine the perceived effects of either actual or hypothetical changes in monetary wealth, while orthogonally manipulating framing, valence, and regulatory focus. We find a significant interaction between the three factors. The gain versus non‐loss asymmetry in perceived satisfaction is stronger in promotion focus, whereas the loss versus non‐gain asymmetry in perceived dissatisfaction is stronger in prevention focus. The results suggest that the effects of incentives framed in terms of (non)gains and (non)losses depend on their congruence with the individual's motivational state.

The author, following constructivist psychoanalysis, observes a dialectic at work in the therapeutic community between knowledge and authority of the analyst and his/her spontaneity on the one hand, and between the formal and informal roles that therapists adopt in a therapeutic community on the other hand. The key to successful therapy, he suggests, lies in maintaining this dialectic. He then goes on to discuss the function of staff teams in therapeutic communities and the importance of taking into account the patients’ unconscious representations of the team. He stresses the need for leadership in therapeutic communities and in engaging with moral issues and not just clinical ones. 相似文献

The aim of this study is to compare the quality of life and the levels of anxiety and depression in a relatively large group of subjects undergoing chemotherapy for soft tissue sarcoma and a control group of subjects undergoing chemotherapy for the most common types of cancer. 56 soft tissue sarcoma affected patients and 56 patients with common tumours, homogeneous in regards to stages of disease and sociodemographic characteristics, were enrolled in two oncological centres in Turin, Italy. Quality of life was assessed by Functional Assessment of Cancer Therapy-General and anxiety and depression by Hospital Anxiety and Depression Scale. All patients had ongoing chemotherapy. The comparison between the two groups shows no difference in either quality of life or in anxiety and depression. There are instead gender differences, since females in the group of common tumours show higher levels of anxiety in comparison to those affected by sarcomas, while males show, at a lower degree, the opposite trend. This study suggest that levels of Quality of Life, anxiety and depression are similar in rare and common tumours. The majority of patients are able to cope with the disease in an adaptive manner. However, for some patients the disease poses a threat to their physical and mental integrity; psychological support of these patients may reduce the development of significant morbidity and help patients to better manage the course of the disease and the effects of the treatment. 相似文献

This paper questions different conceptions of Medical Humanities in order to provide a clearer understanding of what they are and why they matter. Building upon former attempts, we defend a conception of Medical Humanities as a humanistic problem-based approach to medicine aiming at influencing its nature and practice. In particular, we discuss three main conceptual issues regarding the overall nature of this discipline: (i) a problem-driven approach to Medical Humanities; (ii) the need for an integration of Medical Humanities into medicine; (iii) the methodological requirements that could render Medical Humanities an effective framework for medical decision-making. 相似文献

The loss of a parent during childhood is a traumatic experience that can bring about several difficulties in adaptation and psychopathological problems over time during the child’s development. The present study assesses the psychological functioning of a sample of non-referred pre-adolescents and adolescents and considers the impact of the loss of a significant caregiver on their current psychological profiles. Three groups of subjects were considered, as follows: Group A experienced loss between birth and 3 years of age; Group B experienced loss between 3 and 10 years of age; and Group C experienced no loss. The results show that there is a significant decrease in psychopathological risk and improvement in subjects’ scores in the transition from pre-adolescence to mid-late adolescence. Adolescents who have suffered the loss of a caregiver within the first three years of life, however, continue to report higher scores than the other two groups, denoting no improvement in their psychological welfare. 相似文献

In the present study, the use of knowledge space theory (KST), jointly with formal concept analysis (FCA), is proposed for
developing a formal representation of the relations between the items of a questionnaire and a set of psychodiagnostic criteria.
This formal representation can be used to develop an efficient adaptive tool for psychological assessment. Rusch and Wille
(1996) have shown some interesting connections between KST and FCA; these connections are applied in the construction of knowledge
structures, starting from a formal context representing the relations between items and criteria. The proposed general methodology
was applied, as an example, to the Maudsley Obsessional-Compulsive Questionnaire. We used a data set provided by a sample
of patients with a diagnosis of obsessive-compulsive disorder to validate the obtained structures. The parameters of the basic
local independence model (BLIM) were estimated for the obtained knowledge structures. The fit of each model was tested by
parametric bootstrap because of the sparseness of the derived data matrix. The results are discussed in light of both psychological
and methodological relapses. In particular, we propose a reinterpretation of the BLIM parameters that seems suitable for testing
reliability and construct validity; furthermore, it is pointed out how the obtained structures could represent the starting
point for the development of a computerized assessment tool. 相似文献

To study the temperature-dependent structural changes and to analyze the crystal chemical behavior of silver as a function of temperature, a crystal of muthmannite, AuAgTe2, has been investigated by X-ray single-crystal diffraction methods at 300 K and 110 K. At room temperature, muthmannite was confirmed as belonging to the space group P2/m, while at low temperature (110 K) it undergoes a reversible commensurate–incommensurate phase transition with a modulation wave vector q = 0.215(1)a* + 0.379(2)c*. Muthmannite reconverts to the commensurate type upon returning to room temperature, thus indicating that the phase transition is completely reversible in character. The average structure of the low-temperature muthmannite remains monoclinic, space group P2/m, and shows only normal thermal compression over the entire temperature range investigated. Crystal-chemical characteristics are compared with published data on the other members of the system Au–Ag–Te. Speculations on the possible origin of the modulated structure at low temperature are also given. 相似文献
