The present study aimed to investigate whether perceptual completion is available at birth, in the absence of any visual experience. An extremely underspecified kinetic visual display composed of four spatially separated fragments arranged to give rise to an illusory rectangle that occluded a vertical rod (illusory condition) or rotated so as not to elicit perceptual grouping (control condition) was constructed. After newborns' ability to detect the particular kind of rod-and-box display used in the present study had been probed (Experiment 1), they were habituated to the illusory rod-and-box display (Experiment 2), to the control display that did not contain illusory contours (Experiment 3), and to a standard real rod-and-box display akin to those used in previous infants' studies (Experiment 4). Newborns perceived the rod as a connected unit either in the illusory condition (Experiment 2) or in the real condition (Experiment 4), as documented by a preference for a broken rod over a complete rod during the test phase, but not when the occluder was absent (Experiment 3). In all experiments newborns showed no preference between the two test stimuli (control condition), avoiding the possibility that newborns have a spontaneous preference for one test display over the other. Overall, the results of the present study provide evidence that the ability to achieve object unity (1) stems from intrinsic properties of the human perceptual system and (2) is operative from birth, given the right conditions. 相似文献

The following text is the first ever translation into English of a writing by German phenomenologist Hermann Schmitz (*1928).
In it, Schmitz outlines and defends a non-mentalistic view of emotions as phenomena in interpersonal space in conjunction
with a theory of the felt body’s constitutive involvement in human experience. In the first part of the text, Schmitz gives
an overview covering some central pieces of his theory as developed, for the most part, in his massive System of Philosophy, published in German in a series of volumes between 1964 and 1980. Schmitz’s System is centred on the claim that the contemporary view of the human subject is the result of a consequential historical process:
A reductionist and ‘introjectionist’ objectification of lived experience culminating in the ‘invention’ of the mind (or ‘soul’)
as a private, inner realm of subjective experience and in a corresponding ‘grinding down’ of the world of lived experienced
to a meagre, value-neutral ‘objective reality’. To counter this intellectualist trend, Schmitz puts to use his approach to
phenomenology with the aim of regaining a sensibility for the nuanced realities of lived experience—hoping to make up for
what was lost during the development of Western intellectual culture. Since both this text and the overall style of Schmitz’s
philosophising are in several ways unusual for a contemporary readership, a brief introduction is provided by philosophers
Jan Slaby and Rudolf Owen Müllan, the latter of whom translated Schmitz’s text into English. The introduction emphasises aspects
of Schmitz’s philosophy that are likely to be of relevance to contemporary scholars of phenomenological philosophy and to
its potential applications in science and society. 相似文献

Although new venture success is frequently investigated in entrepreneurship, economics, and psychology, the studies published to date vary widely in their theoretical basis, study design, and research methodology. Based on organizational life‐cycle theory and interactional personality theory, this longitudinal study analyses predictors of venture survival. Of 354 small business owners observed over 8 years, 283 (79.9%) still had active businesses at the end of the observation period. A survey instrument was developed to measure the relevant characteristics of the entrepreneurs, their resources, and the environment. Logistic regression models predicting medium‐ and long‐term business survival included these characteristics and the interactions between them entered stepwise as blocks. Startup decisions (line of business, type, and size of planned business) were used as control variables. Much of the variance is explained by our research model (Nagelkerkes R2=.36 for survival at 4 years, and .33 for survival at 8 years). Although long‐term business survival is predicted by the individual variables of startup size and social capital (networks), a larger part of the variance is explained by environment/resource interactions. 相似文献

Suicide prevention especially with psychiatric inpatients is traditionally a very important aspect of psychiatric treatment. During the 1970s and 1980s there was a noticeable increase in so-called hospital suicides in Germany, especially suicides of schizophrenic inpatients. The number of psychiatric inpatient suicides has currently decreased again and a shift to more depressive suicides has also been observed. Furthermore questions which are asked in court are presented and discussed. 相似文献

An attempt is made to give an open account about the goals, problems and results concerning the ending of eight training analyses. The connection of trauma, individual defence structure and mental disturbances as well as the need for their therapeutic change is emphasized. Three problems are offered for further discussion: 1. to transform acting outs of training analysts standing under the pressure of the projections by training analysands onto the institute, into interpretation; 2. the difficulty to understand the varieties of the depressive position within the mental patterns of foreign civilisations; 3. the hypothetical effect of the analysis of character neuroses on the abstinence of training analysts and on the decision for lower frequency by former training analysands. 相似文献

Conventional memory assessment may fail to identify memory dysfunction characterized by intact recall for a relatively brief period but rapid forgetting thereafter. This study assessed learning and retention after 30-min and 24-hr delays on auditory and visual selective reminding tests (SRTs) in right (n=20) and left (n=22) temporal lobe epilepsy (TLE) patients and controls (n=49). The left TLE group performed significantly worse than controls on all 3 trials of both tests. The right TLE group differed from the controls on all 3 visual SRT trials and on learning for the auditory SRT. There were no between-groups differences in rate of information lost at the 30-min versus the 24-hr delay. At the individual level, there was no difference in the percentage of patients versus controls who demonstrated isolated memory impairment at the 24-hr delay. Accelerated forgetting over 24 hr is uncommon in TLE patients. 相似文献

Cannabinoid receptors type 1 (CB1) play a central role in both short-term and long-term extinction of auditory-cued fear memory. The molecular mechanisms underlying this function remain to be clarified. Several studies indicated extracellular signal-regulated kinases (ERKs), the phosphatidylinositol 3-kinase with its downstream effector AKT, and the phosphatase calcineurin as potential molecular substrates of extinction behavior. To test the involvement of these kinase and phosphatase activities in CB1-dependent extinction of conditioned fear behavior, conditioned CB1-deficient mice (CB1(-/-)) and wild-type littermates (CB1(+/+)) were sacrificed 30 min after recall of fear memory, and activation of ERKs, AKT, and calcineurin was examined by Western blot analysis in different brain regions. As compared with CB1(+/+), the nonreinforced tone presentation 24 h after auditory-cued fear conditioning led to lower levels of phosphorylated ERKs and/or calcineurin in the basolateral amygdala complex, ventromedial prefrontal cortex, dorsal hippocampus, and ventral hippocampus of CB1(-/-). In contrast, higher levels of phosphorylated p44 ERK and calcineurin were observed in the central nucleus of the amygdala of CB1(-/-). Phosphorylation of AKT was more pronounced in the basolateral amygdala complex and the dorsal hippocampus of CB1(-/-). We propose that the endogenous cannabinoid system modulates extinction of aversive memories, at least in part via regulation of the activity of kinases and phosphatases in a brain structure-dependent manner. 相似文献

The purpose of this article is to review aspects of the neuropsychology of temporal lobe epilepsy. Evidence will be presented to demonstrate that the cognitive consequences of this focal seizure disorder can be more generalized in nature than expected. Consistent with the extratemporal neurocognitive findings, careful quantitative magnetic resonance imaging volumetrics have shown that structural brain changes may be detected outside the temporal lobes. Many factors can potentially affect cognition and brain structure. We focus on the potential neurodevelopmental impact of early-onset temporal lobe epilepsy on brain structure and cognition positing that this disorder can have both immediate and lifespan implications for cognition and psychosocial status. 相似文献

The present study examined the differential contribution of cortical and subcortical brain structures in emotional processing by comparing patients with focal cortical lesions (n = 32) to those with primarily subcortical dysregulation of the basal ganglia (Parkinson's disease n = 14). A standardized measure of emotional perception (Tübingen Affect Battery) was used. Only patients in the more advanced stages of Parkinson's disease and patients with focal damage to the (right) frontal lobe differed significantly from controls in both facial expression and affective prosody recognition. The findings imply involvement of the fronto-striatal circuitry in emotional processing. 相似文献

Criminal defendants often claim to suffer from amnesia in connection with the events that are the basis of the criminal charges made against them. These claims present difficult problems of proof. Moreover, there are various defenses and opportunities to make pleas in mitigation which present a number of contexts in which evidence of amnesia can be introduced into the criminal trial. This article will examine the significance of amnesia in relation to: (1) a defense based on lack of mens rea; (2) a defense based on diminished capacity; (3) the insanity defense; (4) lack of fitness to stand trial; and (5) sentencing and the death penalty. 相似文献
