The term ‘postmodernism’ has carved itself a niche in everyday, and specialised, vocabulary. We understand it as being the new mentality that emerges from the critique of modernity. This transformation, which has been underway since the second half of the twentieth century, undermines the foremost myth of the modern world, that we can discover an objective and stable truth, that is to say independent and lasting. This change is affecting all areas of human knowledge, from philosophy to physics, as well as human practices and experiences. Its origins are to be found in the theories that label themselves critical, starting with Marxism and existentialism, and in further developments such as hermeneutics, symbolic interactionism, post-structuralism, ethnomethodology, deconstructionism, and others. In this article we wish to recover one of the principal ideas of this change of mentality, the idea of ‘construction of reality’ and contrast it with ‘dependent origination’ (Paticcasamuppada) characteristic of the Dharma, a system of liberation from suffering synthesised by Buddha. We are interested in this relationship in the specific field of Psychotherapy, or in the broader field of Integral Psychology. To this end, firstly we inquire how constructivism has made a space for itself in the scientific world; we then address the constructivist features of the Dharma. 相似文献

This study developed and tested an “Internet-attribute-perception” model that explains how self-disclosure develops in instant messaging (IM) interactions. Following hyperpersonal communication theory, two attributes of computer-mediated communication (i.e., reduced nonverbal cues and controllability) were assumed to be responsible for increased online self-disclosure in IM. However, our model posed that any actual effects of these attributes would depend on users' perceptions of the relevance of these attributes. Furthermore, our model posed that these perceptions would mediate the relationship between personality characteristics (i.e., pri vate and public self-consciousness, and social anxiety) and online self-disclosure. Using structural equation modeling on a sample of 1,203 Dutch adolescents, we found that adolescents' perceptions of the relevance of reduced nonverbal cues and controllability encouraged their feelings of disinhibition, which in turn increased their online self-disclosure. As expected, private and public self-consciousness and social anxiety stimulated adolescents' perceptions of the relevance of reduced nonverbal cues and controllability, but did not directly influence online self-disclosure. The study shows the vital role of users' perceptions of CMC attributes in Internet-effects research. 相似文献

Poststroke depression (PSD) is the most frequent psychological sequela following stroke. While previous studies describe the impact of age on brain infarct volume, brain edema, and blood–brain barrier (BBB) breakdown following ischemia, the role of age on PSD has yet to be described. Here, we examine the influence of age on PSD progression in a rat model of PSD by middle cerebral artery occlusion (MCAO). One hundred forty-three rats were divided into three groups. 48 rats 20 weeks of age underwent a sham procedure, 51 rats 20 weeks of age had MCAO, and 44 rats 22–26 months of age had MCAO. Groups were further divided into two subgroups. The first subgroup was used to measure infarct lesion volume, brain edema, and BBB breakdown at 24 h. In the second subgroup at 3 weeks after MCAO, rats were subjected to a sucrose preference test, two-way shuttle avoidance task, forced swimming test, and a brain-derived neurotrophic factor (BDNF) protein level measurement. Total and striatal infarct volume, brain edema, and BBB breakdown in the striatum were increased in older rats, as compared with younger rats. While both old and young rats exhibited depressive-like behaviors on each of the behavioral tests and lower BDNF levels post-MCAO, as compared with control rats, there were no differences between old and young rats. Although older rats suffered from larger infarct volumes, increased brain edema and more BBB disruption following MCAO, the lack of behavioral differences between young and old rats suggests that there was no effect of rat age on the incidence of PSD. 相似文献

Although the existence of implicit motor learning is now widely accepted, the findings concerning perceptual implicit learning are ambiguous. Some researchers have observed perceptual learning whereas other authors have not. The review of the literature provides different reasons to explain this ambiguous picture, such as differences in the underlying learning processes, selective attention, or differences in the difficulty to express this knowledge. In three experiments, we investigated implicit visual learning within the original serial reaction time task. We used different response devices (keyboard vs. mouse) in order to manipulate selective attention towards response dimensions. Results showed that visual and motor sequence learning differed in terms of RT-benefits, but not in terms of the amount of knowledge assessed after training. Furthermore, visual sequence learning was modulated by selective attention. However, the findings of all three experiments suggest that selective attention did not alter implicit but rather explicit learning processes. 相似文献

ABSTRACTIn spatial compatibility tasks, when the spatial location of a stimulus is irrelevant it nevertheless interferes when a response is required in a different spatial location. For example, response with a left key-press is slowed when the stimulus is presented to the right as compared to the left side of a computer screen. However, in some conditions this interference effect is not detected in reaction time (RT) measures. It is typically assumed that the lack of effect means the irrelevant spatial code was not analysed or that the information rapidly decayed before response. However, we show that even in conditions where there appears to be no spatial interference when measuring RTs, effects can nevertheless be detected after response when recording facial electromyography responses. This dissociation between two measures highlights the importance of diverging methods to investigate visuomotor processes as conclusions based on only one measure can be misleading. 相似文献

We review the recent research literature on pro-criminal attitudes (PCAs) as a causal factor of recidivism with a focus on studies on the effectiveness of offender treatment programs targeting PCAs to prevent recidivism. The main conclusions that can be derived from the literature are: (1) the evidence supports the hypothesis that PCAs are related to reoffending; (2) most investigated offender treatment programs tend to reduce PCAs, although the general lack of adequate control group designs does not rule out alternative explanations for this reduction; and (3) there is no conclusive empirical evidence that intervention programs designed to reduce PCAs are effective in reducing recidivism. Empirical research in this area lacks the theoretical and methodological rigor to test causal models of the influence of treatment on reducing PCAs, and effects of PCAs on recidivism. Limitations of the empirical evidence are related to inadequate research designs and/or suboptimal data analysis strategies. Recommendations concerning optimized research designs and data analysis strategies that are likely to provide more conclusive evidence on the relation of PCAs, PCA treatment, and recidivism are given. 相似文献

The question of when other people’s bad acts belong on our moral ledger arises in a number of different scenarios. Each scenario has received some philosophical attention, but no one has noted the structural similarities of these various scenarios or the implications of a proposed approach to one for how the others should be approached. That is the ambition of this article. In it, seemingly disparate moral phenomena—blunt rules, preemptive restrictions, moral blackmail, complicity, retreat and proportional response, and the duty to rescue from a peril one has caused—are shown to have similar structures and thus to require similar moral approaches. 相似文献

Various authors have referred to an association between neglect and non‐spatial components of attention. It has been suggested that an increase in attentional load could exacerbate neglect symptoms and reveal subtle, well‐compensated neglect. In the present study, 21 RH and 22 LH subacute stroke patients and 20 controls performed a computerized single‐detection task (CVRT) and a dual task (CVRT‐D) combining the detection task with a driving simulation task. Omissions, reaction times (RTs) and RT asymmetries were analysed to investigate the influence of increasing attentional load on neglect symptoms. RT asymmetries were most pronounced in RH patients. Although a clear increase in RT asymmetries between CVRT and CVRT‐D was observed, the amount of increase did not differ between both patient groups. Within both patient groups, correlations between RT asymmetries and ipsilesional RTs as a measure of general attention were significant in the single task but not in the dual task, indicating that increased attentional load may result in different degrees of lateralized and general attentional problems. Half of the patients with neglect on the BIT (Behavioural Inattention Test) showed increased RT asymmetries from CVRT to CVRT‐D. Moreover, two LH and RH patients without neglect symptoms on the BIT and CVRT showed distinctively increased asymmetries in the CVRT‐D, fostering the idea of an emergence of subtle neglect under increased attentional load. Dual‐task performance may draw attention towards patients who, without obvious signs of neglect, may show visuospatial attention deficits in complex situations. 相似文献

In the structure-from-motion paradigm, physical motion on a screen produces the vivid illusion of an object rotating in depth. Here, we show how to dissociate illusory depth and illusory rotation in a structure-from-motion stimulus using a rotationally asymmetric shape and reversals of physical motion. Reversals of physical motion create a conflict between the original illusory states and the new physical motion: Either illusory depth remains constant and illusory rotation reverses, or illusory rotation stays the same and illusory depth reverses. When physical motion reverses after the interruption in presentation, we find that illusory rotation tends to remain constant for long blank durations (T blank ≥ 0.5 s), but illusory depth is stabilized if interruptions are short (T blank ≤ 0.1 s). The stability of illusory depth over brief interruptions is consistent with the effect of neural persistence. When this is curtailed using a mask, stability of ambiguous vision (for either illusory depth or illusory rotation) is disrupted. We also examined the selectivity of the neural persistence of illusory depth. We found that it relies on a static representation of an interpolated illusory object, since changes to low-level display properties had little detrimental effect. We discuss our findings with respect to other types of history dependence in multistable displays (sensory stabilization memory, neural fatigue, etc.). Our results suggest that when brief interruptions are used during the presentation of multistable displays, switches in perception are likely to rely on the same neural mechanisms as spontaneous switches, rather than switches due to the initial percept choice at the stimulus onset. 相似文献

The paper raises some difficulties for the typical motivations behind set reductionism, the view that sets are reducible to entities identified independently of set theory. 相似文献
