This paper argues that Derrida’s aporetic conclusions regarding moral and political concepts, from hospitality to democracy,
can only be understood and accepted if the notion of différance and similar infrastructures are taken into account. This is
because it is the infrastructures that expose and commit moral and political practices to a double and conflictual (thus aporetic)
future: the conditional future that projects horizonal limits and conditions upon the relation to others, and the unconditional
future without horizons of anticipation. The argument thus turns against two kinds of interpretation: The first accepts normative
unconditionality in ethics but misses its support by the infrastructures. The second rejects unconditionality as a normative
commitment precisely because the infrastructural support for unconditionality seems to rule out that it is normatively required.
In conclusion, the article thus reconsiders the relation between a quasi-transcendental argument and its normative implications,
suggesting that Derrida avoids the naturalistic fallacy. 相似文献

Listeners tune in to talkers’ vowels through extrinsic normalization. We asked here whether this process could be based on compensation for the long-term average spectrum (LTAS) of preceding sounds and whether the mechanisms responsible for normalization are indifferent to the nature of those sounds. If so, normalization should apply to nonspeech stimuli. Previous findings were replicated with first-formant (F1) manipulations of speech. Targets on a [pt]–[p?t] (low–high F1) continuum were labeled as [pt] more after high-F1 than after low-F1 precursors. Spectrally rotated nonspeech versions of these materials produced similar normalization. None occurred, however, with nonspeech stimuli that were less speechlike, even though precursor–target LTAS relations were equivalent to those used earlier. Additional experiments investigated the roles of pitch movement, amplitude variation, formant location, and the stimuli's perceived similarity to speech. It appears that normalization is not restricted to speech but that the nature of the preceding sounds does matter. Extrinsic normalization of vowels is due, at least in part, to an auditory process that may require familiarity with the spectrotemporal characteristics of speech. 相似文献

Self‐ratings of personality predict academic success above general intelligence. The present study replicated these findings and investigated the increment of other‐ratings or intentionally distorted self‐ratings. Participants (N = 145) had to compile a personality questionnaire twice. First they were given neutral instructions. The second time they were asked to imagine a specific applicant setting. Furthermore, two peers rated each participant. Additionally, verbal, numerical and figural reasoning scores were obtained. Grades on a statistics exam obtained 2 months later served as the criterion. Results replicated prior findings and showed incremental validity for self‐ and other‐rated personality, which was stable after controlling for intelligence. Faking had no impact on the domain‐score level, but results on the facet‐score level were less encouraging. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Theories of epistemology make reference—via the perspective of an observer—to the structure of information transfer, which
generates reality, of which the observer himself forms a part. It can be shown that any epistemological approach which implies
the participation of tautological structural elements in the information transfer necessarily leads to an antinomy. Nevertheless,
since the time of Aristotle the paradigm of mathematics—and thus tautological structure—has always been a hidden ingredient
in the various concepts of knowledge acquisition or general theories of information transfer. We hold that Darwin’s Evolutionary
Theory is the first scientific theory which consistently presupposes a non-tautological structure for the information transfer
and, at the same time, keeps it strictly distinct from the tautological metric of scientific observation. The consequences
of this technique—namely the dissociation of information from intentionality—have not yet been fully drawn. 相似文献

Intra-individual reaction time variability (IIV) in neuropsychological task performance reflects short term fluctuations in performance. Increased IIV has been reported in patients with schizophrenia and could be related to a deficient neural timing mechanism, but the role of IIV in adult patients with other psychiatric disorders has not been established. Therefore, we compared IIV measures obtained in a Go/Nogo task from patients with schizophrenia, major depression and borderline personality disorder. IIV was increased for patients with schizophrenia. When correcting for differences in mean reaction time, depressive and borderline patients also showed increased IIV. Importantly, all groups showed a strong association between IIV and accuracy of task performance. This suggests that increased IIV might be a sensitive marker for the efficiency of top-down attentional control in all diagnostic groups. Aside from these similarities, the complete results including measures of IIV, mean reaction time and accuracy show differential patterns for patients with schizophrenia compared to those with borderline personality disorder or depression. These results are discussed with respect to common versus disorder-specific neural mechanisms underlying increased IIV. 相似文献

The mechanisms underlying the right hemisphere's dominance for spatial and attentional functions lacks a comprehensively explanation. For example, perceptual biases, as observed in line bisection and related tasks, might be caused by an attentional asymmetry or by perceptual processes such as a specialization of the left and right hemisphere for high and low spatial frequencies (SFs), respectively. Here we used the gratingscales task to measure perceptual bias in SF judgements, and we cued participants' attention either to high or low SFs. Participants showed a leftward bias when comparing the high SF components of the stimulus, and a rightward bias when comparing the low SF components-opposite to what would be expected from a hemispheric lateralization for SFs. Two control experiments used different strategies to manipulate the width of the attentional window. However, we observed no influence on perceptual bias, thus ruling out the possibility that the results in Experiment 1 were due to differences in attentional window size. These data support the idea of an attentional asymmetry underlying perceptual bias. Our results provide novel support for the role of attentional asymmetry in perceptual biases. 相似文献

Two psychophysical experiments are reported, one dealing with the visual perception of the head orientation of another person (the 'looker') and the other dealing with the perception of the looker's direction of eye gaze. The participant viewed the looker with different retinal eccentricities, ranging from foveal to far-peripheral viewing. On average, judgments of head orientation were reliable even out to the extremes of peripheral vision (90 degrees eccentricity), with better performance at the extremes when the participant was able to view the looker changing head orientation from one trial to the next. In sharp contrast, judgments of eye-gaze direction were reliable only out to 4 degrees eccentricity, signifying that the eye-gaze social signal is available to people only when they fixate near the looker's eyes. While not unexpected, this vast difference in availability of information about head direction and eye direction, both of which can serve as indicators of the looker's focus of attention, is important for understanding the dynamics of eye-gaze behavior. 相似文献

Past research on the accuracy of personality judgments has largely focused on person perception scenarios that are public in nature (e.g., face-to-face interactions, personal websites). This study investigated the accuracy of personality judgments on the basis of highly private information: a person’s natural stream of thought. Nine naïve judges rated the personality of 90 targets on the basis of their 20-min stream-of-consciousness essays. Judges’ level of accuracy was significant and substantial for all Big Five dimensions. The substantial and relatively uniform accuracy across all Big Five dimensions suggests that a person’s moment-to-moment thoughts provide good information for the accurate judgment of personality in general rather than specific diagnostic information for the accurate judgment of private traits such as Neuroticism. 相似文献

The authors used the Electronically Activated Recorder (EAR) to track within-day variability in everyday behaviors associated with positive and negative affect across two samples. The EAR is a portable audio recorder that periodically samples snippets of ambient sounds from participants’ momentary environments. The recorded sounds are then coded for different behaviors. The study tested whether previous findings regarding diurnal patterns in self-reported mood extend to naturalistically observed behavior. Across both samples, behavior associated with positive affect (i.e., socializing, laughing, and singing) varied according to a sinusoidal 24-h rhythm centered around participants’ average waketime while behavior associated with negative affect (i.e., arguing and sighing) did not. Further, there was preliminary evidence that personality traits can moderate these rhythms (e.g., their amplitude). 相似文献
