An enhancement of the UV-visible optical absorption spectra of Ag nanoparticles (NPs) deposited on indium tin oxide (ITO) surfaces of different resistance by a seed-mediated growth technique is presented. A bicolour coherent beam, obtained from a pulsed Nd:YAG laser providing a 1060-nm fundamental wavelength and a double-frequency one at 530?nm, was used. A significant change in the optical density is observed for Ag NPs on low-resistance ITO surfaces (≈4?Ω/square), while almost nothing occurs with high-resistance (≈50?Ω/square surfaces). The spectral position of the maximal absorption at 440?nm is almost preserved in both cases. This result is explained in terms of a local photoinduced static field and surface-plasmon polaritons interacting with photoexcited phonons. A grating effect, arising from the coherent bicolour light forming a superstructure as for quantum crystals, could be another contribution. 相似文献

In three experiments, adult subjects' explanations of the observed nonpermanence of a physical object and their recollections of the order of the events during the experiment were obtained and analysed. The data showed that in order to conserve their strong beliefs in object permanence subjects systematically distorted the real temporal succession of events preceding the phenomenon. The frequency of the distortions depended on the salience of the nonpermanence phenomenon (“disappearance” versus “appearance” of the physical object) and on the time interval between the events whose temporal order was reversed, but not on subjects' nationality (English versus German), gender, type of reproduction (immediate versus delayed), role in the experiment (subject versus observer), and degree of prompting in questioning. 相似文献

Prospective memory (PM) refers to remembering to perform an action in the future. One hundred and twenty-nine students completed a laboratory event–based PM task as well as depression and anxiety questionnaires. The data were analysed with the beta-MPT version of the multinomial processing tree model of event-based PM. Thereby, the prospective and retrospective components of PM were estimated for each participant and were then correlated with depression and anxiety. State anxiety was negatively correlated with the prospective component of PM. Neither depression nor trait anxiety were related to either component of PM. 相似文献

In this article we outline a “sub-process view” of working memory capacity (WMC). This view suggests that any relationship between WMC and another construct (e.g., reading comprehension) is actually a relationship with a specific part of the WMC construct. The parts, called sub-processes, are functionally distinct and can be measured by intrusion errors in WMC tasks. Since the sub-processes are functionally distinct, some sub-process may be related to a certain phenomenon, whereas another sub-process is related to other phenomena. In two experiments we show that a sub-process (measured by immediate/current-list intrusions) is related to the effects of speech on prose memory (semantic auditory distraction), whereas another sub-process (measured by delayed/prior-list intrusions), known for its contribution to reading comprehension, is not. In Experiment 2 we developed a new WMC task called “size-comparison span” and found that the relationship between WMC and semantic auditory distraction is actually a relationship with a sub-process measured by current-list intrusions in our new task. 相似文献

Abstract Two experiments studied memory for the appearance of a Danish 20 kroner coin. The coin bears the portrait of Queen Margrethe II in profile, facing to the right. Previous studies have examined memory for British coins, which similarly bear a right-facing portrait of Queen Elizabeth II. They have revealed the occurrence of a mnemonic illusion, in that British people tend to believe the portrait faces left. This finding has been attributed to the occurrence of a joint coin-stamp schema. British stamps bear a left-facing profile of the Queen, and it is possible that information from the stamp predominates in the formation of the schema. In the case of Denmark, however, stamps bear a full-face portrait of the Queen. Nevertheless, the present experiments showed that the Coin Head Illusion is also found in Denmark. That is, the number of participants recalling the Queen's head as facing to the right was significantly below even the chance level of 50%. Further, this result occurred both for residents of Denmark and for visitors to Denmark. These findings suggest that the bias underlying the Coin Head Illusion may be a more general one than that envisaged by the joint coin-stamp schema hypothesis. 相似文献

Abstract Hintzman (1991; 1992) has claimed that the reason data points approximate the recognition failure function discovered by Tulving and Wiseman (1975) is that they are mathematically constrained to do so, and the reason that a few data points do not approximate the function, but are exceptions to it, is that these data points are less subject to mathematical constraints. He has additionally argued that such exceptions are more likely with low levels of recall and strong underlying sources of positive covariance. We provide empirical evidence relevant to this mathematical model using 301 observations from a database of all relevant experimental conditions published between 1973 and 1992 (Nilsson & Gardiner, 1993). We conclude that mathematical constraints have only a minor influence on the function, not the causal role assigned to them in Hintzman's (1992) model. By our account, both the function and exceptions to it reflect a single psychological principle, the functional effectiveness of contextual cues. 相似文献

The present article reports a controlled intervention study concerning the effects of a nondirected use of pictures of works of art as a way of stimulating creativity in elderly institutionalized women. Participants were randomly allocated either to the intervention (n = 20) or to the control (n = 20) group. After the intervention significant improvement in ratings between the groups was measured, with the intervention group more open and flexible and with a stronger deposition to a creative behavior than subjects in the control group. They also showed greater freedom and variation than the control group in drawing circles and making pictures. In puzzle tests the intervention group constructed increasingly imaginative, irregular, and open alternatives with colored patterns. The control group constructed closed and black forms. Importantly, the status of increased creativity continued to exist four months after the intervention. No changes were seen in the control group. This group showed a rational and precautious personality. 相似文献

This paper is the second of two essays designed to acquaint English-speaking readers with the work of Avksenty Tcezarevich Puni (1898–1986), one of the fathers of Russian sport psychology. In our previous essay “The Russian origins of sport psychology: a translation of an early work of A. Tc. Puni” (Ryba, Stambulova, & Wrisberg, 2005), we discussed Puni's innovative ideas of psychological preparation of athletes based on his classic paper “Psychological preparation of athletes for a competition” that was published in 1963. In that essay, we grounded Puni's pioneering work within the specific socio-political and historical context of his era by providing a brief overview of his life (including extensive explanatory footnotes) in pre- and post-Socialist Revolution Russia. In this paper, we attempt to further historicize the work of Puni on the psychological preparation of athletes by discussing his ground-breaking model of Psychological Preparation for a Competition (PPC) and contrasting that work with the activity of sport psychology consultants taking place in North America during the same time period (i.e., 1960s and 1970s). In a concluding section, we will discuss some of the lessons sport psychology consultants have learned in the decades since Puni developed his model and suggest some ways future models might expand on Puni's view of the provision of psychological assistance for athletes. 相似文献
