The generation effect occurs if people remember items they complete from fragments better than complete items they read. Four experiments investigate two questions. When does the effect occur, and why does it do so? Targets generated in related contexts are recognized better than read targets, and they are recalled better with the contexts as cues; the contexts are recognized equally well, and the relation between the context and target is not enhanced by generation. Furthermore, generated items exceed items read in pure lists even when read ones from the mixed list are no worse than the controls. The generation effect is real; it is not an artifact. However, there is nothing special about generation. Generating is a type of encoding, and like any other type of encoding, its effects are maximal on tests that require subjects to do again whatever they did at study. Generating makes targets distinctive by contrasting them with other relatives of the context, and, as a result, the targets enjoy benefits in later discriminations within their family.

The field of polymer/surfactant interaction is reviewed in this work. Results from two investigative methods,viz., dialysis and surface tension, are discussed, illustrating the main behavioral patterns and outlining the principles of the
interactions. Next, aspects of the interaction phenomena that appear to have relevance to detergent formulation are presented.
These include solution rheology, solubility control and surface conditioning. Lastly, the importance of surface activity of
the polymer itself is stressed, culminating in a discussion of the properties of hydrophobically modified water-soluble polymers
(“polymeric surfactants”), both alone and in the presence of conventional surfactants.
Based on the Samuel Rosen Memorial Award lecture, given at the AOCS Annual Meeting, Anaheim, CA, April 1993. 相似文献

A temperature-controlled tunable optical filter for use in the visible range and based on the Christiansen effect, in which the solid particles have been substituted with glass fibers, has been fabricated and tested. The construction of the filter and transmission properties are reported. For an operating temperature of 95°C, the peak wavelength was 509.5 nm, with a peak transmission of 50.8% and a FWHM of 71 nm. 相似文献

Mobile robotic systems must sense constraints imposed by a dynamically changing environment and predictably react to those changes in real-time. Complexity arises in mobile robotic systems because the computing platform travels through the environment with which the system is interacting. These systems have spatio-temporal requirements in the sense that correct behavior is defined in terms of both space and time. The focus of this paper is mobile robotic platforms that must sense their environment and avoid obstacles as they navigate from one point to another. We present a design and analysis methodology for these platforms that integrates spatio-temporal attributes with fixed priority real-time scheduling through the use of zone and processing window abstractions. 相似文献

In this work, a first approach to a robust phoneme recognition task by means of a biologically inspired feature extraction method is presented. The proposed technique provides an approximation to the speech signal representation at the auditory cortical level. It is based on an optimal dictionary of atoms, estimated from auditory spectrograms, and the Matching Pursuit algorithm to approximate the cortical activations. This provides a sparse coding with intrinsic noise robustness, which can be therefore exploited when using the system in adverse environments. The recognition task consisted in the classification of a set of 5 easily confused English phonemes, in both clean and noisy conditions. Multilayer perceptrons were trained as classifiers and the performance was compared to other classic and robust parameterizations: the auditory spectrogram, a probabilistic optimum filtering on Mel frequency cepstral coefficients and the perceptual linear prediction coefficients. Results showed a significant improvement in the recognition rate of clean and noisy phonemes by the cortical representation over these other parameterizations. 相似文献

Monte Carlo and finite element methods are numerical techniques used for solving complex problems in reactor physics and radiation shielding. In this paper we are concerned with the implementation of existing research-level codes based on these two methods, written originally for serial computers, on an MIMD transputer-based system. Results and performance of the parallelized codes are presented. 相似文献

Innovative daylighting systems have four key aims; to increase daylight levels deep within rooms, to improve daylight uniformity, to control direct sunlight and to reduce glare. Results from experimental studies at the Building Research Establishment (BRE) indicated that the systems tested (prismatic glazing, prismatic film, mirrored louvres and light shelves) usually reduced illuminances at the rear of rooms compared with unshaded windows. It is concluded that, in the UK at least, innovative daylighting systems should be designed primarily as shading devices, controlling glare while admitting more daylight than conventional blinds. 相似文献

An empirically valid outcome in psychology may differ in the degree to which the outcome does or does not conform to human intuition. The author provides a brief history of three psychological outcomes violating human intuition, notes the resemblance to the common sense revolution, and then discusses how human intuition may be detrimental to behaviorism and evolutionary perspectives of human nature. The role of human intuition in supernatural beliefs is considered and, finally, possible methods to improve the plausibility of counterintuitive outcomes are suggested.
