Perception Of Time

Theories which construct perception of time from content of input predict monotonic functions of rate-judged duration of stimuli, and do not account for intersensory differences. Two experiments required Ss to compare directly the durations of paired lights or sounds pulsed at various rates to produce discriminable beats and flickers (6.0, 10.0, 14.0 Hz), and steady signals. Pulsed lights, not sounds, were judged longer than steady, and this visual effect was identical for all flicker rates. Faster pulsed sounds and lights were judged longer than slower ones for all frequency combinations except for 10.0- to 14.0-Hz comparisons with vision. No monotonic function of rate-judged durations of pulses was obtained; the effect was all-or-none. Although pulse rate did affect judged duration, neither simple functions nor symmetry across senses was found.

Some procedures for synthesizing values of judgements in multicriteria decision making have been provided by several authors. The functionals of synthesis they consider are frequently means. The most general form of these operators involves both a weighting function w and a continuous and strictly monotonic function φ. Our aim is to analyze the behaviour of the aggregation operator Fωφ depending on w and φ. To this purpose we introduce a pre-ordering relation on the set W of weighting functions and on the set Φ of continuous and strictly monotonic functions, which allows us to compare the synthesizing functionals.

AbstractWe examine recursive monotonic functions on the Lindenbaum algebra of $EA$. We prove that no such function sends every consistent φ to a sentence with deductive strength strictly between φ and $\left( {\varphi \wedge Con\left( \varphi \right)} \right)$. We generalize this result to iterates of consistency into the effective transfinite. We then prove that for any recursive monotonic function f, if there is an iterate of $Con$ that bounds f everywhere, then f must be somewhere equal to an iterate of $Con$.

AbstractLet f be an operator monotonic function on I and A, B∈I (H), the class of all selfadjoint operators with spectra in I. Assume that p : [0.1], →ℝ is non-decreasing on [0, 1]. In this paper we obtained, among others, that for A ≤ B and f an operator monotonic function on I,\matrix{0 \hfill & { \le \int\limits_0^1 {p\left( t \right)f\left( {\left( {1 - t} \right)A + tB} \right)dt - \int\limits_0^1 {p\left( t \right)dt\int\limits_0^1 {f\left( {\left( {1 - t} \right)A + tB} \right)dt} } } } \hfill \cr {} \hfill & { \le {1 \over 4}\left[ {p\left( 1 \right) - p\left( 0 \right)} \right]\left[ {f\left( B \right) - f\left( A \right)} \right]} \hfill \cr }in the operator order.Several other similar inequalities for either p or f is differentiable, are also provided. Applications for power function and logarithm are given as well.

AbstractTo explore the effectiveness of microgravity simulated by head-down bed rest (HDBR) and artificial gravity (AG) with exercise on lung function. Twenty-four volunteers were randomly divided into control and exercise countermeasure (CM) groups for 96 h of 6° HDBR. Comparisons of pulse rate, pulse oxygen saturation (SpO2) and lung function were made between these two groups at 0, 24, 48, 72, 96 h. Compared with the sitting position, inspiratory capacity and respiratory reserve volume were significantly higher than before HDBR (0° position) (P< 0.05). Vital capacity, expiratory reserve volume, forced vital capacity, forced expiratory volume in 1 s, forced inspiratory vital capacity, forced inspiratory volume in 1 s, forced expiratory flow at 25, 50 and 75%, maximal mid-expiratory flow and peak expiratory flow were all significantly lower than those before HDBR (P< 0.05). Neither control nor CM groups showed significant differences in the pulse rate, SpO2, pulmonary volume and pulmonary ventilation function over the HDBR observation time. Postural changes can lead to variation in lung volume and ventilation function, but a HDBR model induced no changes in pulmonary function and therefore should not be used to study AG CMs.

Perception Of Time

For Gilles Deleuze's two essays ‘Causes and Reasons of Desert Islands’ and ‘Michel Tournier and the World Without Others’, the crucial question is what the perception is, what its fundamental conditions are. A desert island can be a place to experiment on this question. The types of perception are described in many critical works about the history of art and aesthetical reflections by artists. So I will try to retrace some types of perception especially linked to the ‘haptic’, the importance of which was rediscovered by Deleuze. The ‘haptic’ proposes a type of perception not linked to space, but to time in its aspects of genesis. And something incorporeal has to intervene in a very original stage of perception and of perception of time. Thus we will be able to capture some links between the fundamental aspects of perception and time in its ‘out of joint’ aspects (Aion).
