Build-up of proactive interference (PI) with visual-picture and auditory-verbal input modalities and the subsequent release from PI following a change in modality was investigated in three experiments with boys and girls, as follows: Experiment I (n = 64) at two mean age levels, 7–6 and 10–5; Experiment II (n = 64) at mean age 7–6; and Experiment III (n = 48) at age 11–4. PI build-up occurred in both modalities for all ages tested. Release from PI occurred following a change from auditory to visual input but not following a visual to auditory shift. In the final experiment, this asymmetrical improvement in performance was dependent upon an interaction between the modality of the input and distractor task on the final or release trial; changing to visual input produced a release effect regardless of the distractor task modality, while auditory input was associated with improvement in recall if a visual distractor task was employed whether or not a shift in input modality had occurred. This improvement was hypothesized to represent a decrease in retroactive interference rather than a release from proactive interference.  相似文献

According to Cantor (Mathematische Annalen 21:545–586, 1883; Cantor’s letter to Dedekind, 1899) a set is any multitude which can be thought of as one (“jedes Viele, welches sich als Eines denken läßt”) without contradiction—a consistent multitude. Other multitudes are inconsistent or paradoxical. Set theoretical paradoxes have common root—lack of understanding why some multitudes are not sets. Why some multitudes of objects of thought cannot themselves be objects of thought? Moreover, it is a logical truth that such multitudes do exist. However we do not understand this logical truth so well as we understand, for example, the logical truth ${\forall x \, x = x}$ . In this paper we formulate a logical truth which we call the productivity principle. Rusell (Proc Lond Math Soc 4(2):29–53, 1906) was the first one to formulate this principle, but in a restricted form and with a different purpose. The principle explicates a logical mechanism that lies behind paradoxical multitudes, and is understandable as well as any simple logical truth. However, it does not explain the concept of set. It only sets logical bounds of the concept within the framework of the classical two valued ${\in}$ -language. The principle behaves as a logical regulator of any theory we formulate to explain and describe sets. It provides tools to identify paradoxical classes inside the theory. We show how the known paradoxical classes follow from the productivity principle and how the principle gives us a uniform way to generate new paradoxical classes. In the case of ZFC set theory the productivity principle shows that the limitation of size principles are of a restrictive nature and that they do not explain which classes are sets. The productivity principle, as a logical regulator, can have a definite heuristic role in the development of a consistent set theory. We sketch such a theory—the cumulative cardinal theory of sets. The theory is based on the idea of cardinality of collecting objects into sets. Its development is guided by means of the productivity principle in such a way that its consistency seems plausible. Moreover, the theory inherits good properties from cardinal conception and from cumulative conception of sets. Because of the cardinality principle it can easily justify the replacement axiom, and because of the cumulative property it can easily justify the power set axiom and the union axiom. It would be possible to prove that the cumulative cardinal theory of sets is equivalent to the Morse–Kelley set theory. In this way we provide a natural and plausibly consistent axiomatization for the Morse–Kelley set theory.  相似文献

Traditionally Right‐Wing Authoritarianism (RWA) has been seen as a unidimensional construct. Recently, however, researchers have begun to measure three distinct RWA dimensions (Feldman, 2003; Funke, 2005; Van Hiel, Cornelis, Roets, & De Clercq, 2006). One of these new multidimensional RWA approaches has conceptualized these three dimensions as Authoritarianism, Conservatism, and Traditionalism (ACT), which are viewed as expressions of basic social values or motivational goals that represent different, though related, strategies for attaining collective security at the expense of individual autonomy. Findings are reported from two studies to assess the validity and predictive utility of the multidimensional ACT approach. First, a direct cross‐national comparison showed that the three ACT dimensions were reliable and factorially distinct and demonstrated the measurement invariance of the three latent constructs across Serbian and NZ (New Zealand) samples. The three ACT dimensions predicted self‐reported behavior differentially in both samples, and a comparison of latent means showed the Serbian sample higher than the NZ sample on the ACT dimensions of Authoritarianism and Traditionalism but markedly lower on Conservatism. Second, a reanalysis of previously collected NZ data showed that the three ACT scales differentially predicted three dimensions of generalized prejudice in a theoretically meaningful manner. These findings underline the importance of studying ideological attitudes, such as RWA, multidimensionally.  相似文献

When modelling realistic systems, physical constraints on the resources available are often required. For example, we might say that at most N processes can access a particular resource at any moment, exactly M participants are needed for an agreement, or an agent can be in exactly one mode at any moment. Such situations are concisely modelled where literals are constrained such that at most N, or exactly M, can hold at any moment in time. In this paper we consider a logic which is a combination of standard propositional linear time temporal logic with cardinality constraints restricting the numbers of literals that can be satisfied at any moment in time. We present the logic and show how to represent a number of case studies using this logic. We propose a tableau-like algorithm for checking the satisfiability of formulae in this logic, provide details of a prototype implementation and present experimental results using the prover.  相似文献

Based on a new theoretical framework—the Social Relations Lens Model—this study examined the influence of personality on real‐life attraction at zero acquaintance. A group of psychology freshmen (N = 73) was investigated upon encountering one another for the first time. Personality traits, attraction ratings and metaperceptions were assessed using a large round‐robin design (2628 dyads). In line with our model, personality differentially predicted who was a liker and who expected to be liked (perceiver effects), who was popular and who was seen as a liker (target effects), as well as who liked whom and who expected to be liked by whom (relationship effects). Moreover, the influence of personality on attraction was mediated by observable physical, nonverbal and audible cues. Results allowed a closer look at first sight and underline the importance of combining componential and process approaches in understanding the interplay of personality and social phenomena.

This essay analyzes the recent appearance in Russian letters of ultra-nationalist fantasies about the restoration of Russia??s imperial or totalitarian status. This new trend has its roots not only in the increasingly patriotic tone of Russian society and politics, but also in the dynamics of the literary field itself. ??Imperialist writers?? such as Aleksandr Prokhanov and Pavel Krusanov have both revived and reacted against postmodern themes and motifs from earlier decades. Relying on the legacy of sots-art and stiob, the ??imperialists?? advance a new model in Russia??s postmodern tradition, one that is balanced on the very borderline between irony and ideological militancy. In playing the game of ambiguous fanaticism, these writers have been able to attract the attention of a broad and diverse public, and have moved from an intellectual periphery into the cultural mainstream.  相似文献

The Druze are a small ethnic minority in Israel amounting to about 130,000 residents (or 1.7 % of the total population of the country). Unlike other population groups, the Druze strive to keep their own traditions and marry mainly inside their own community. During the last decade, cancer morbidity among both Jews and Arabs in Israel has been increasing, while data on the Druze are little known and have not been analyzed and compared to other population groups to date. To compare cancer morbidity rates among Druze, Arabs and Jews in Israel during 1999–2009, gender-specific and age-standardized incidence rates of all site cancers and specific cancers of three population groups (Jews, Arabs and Druze) were received from the Israel National Cancer Registry for the period 1999–2009. Based on these rates, periodical incidence rates were calculated and mutually compared across the groups stratified by gender. As the analysis shows, the Druze had significantly lower cancer rates compared to both Arabs and Jews. Thus, for all site cancers, there were significantly higher cancer rates in Jewish males versus Druze males (RR = 1.39, 95 % CI = 1.16–1.65) and in Jewish females versus Druze females (RR = 1.53, 95 % CI = 1.27–1.85), but not statistically significant for Arab males versus Druze males (RR = 1.12 95 % CI = 0.93–1.35). Lung cancer rates in Arab males were also higher compared to Druze males (RR = 1.84, 95 % CI = 1.13–3.00). Jewish males had statistically significant higher rates of prostate cancer compared to Druze males (RR = 2.47, 95 % CI = 1.55–3.91). For thyroid and colon cancers, risks were not significantly different at the 95 % CI level; however, the risks were significantly different at the 90 % CI level (RR = 3.62, 90 % CI 1.20–11.02 and RR = 1.69, 90 % CI = 1.03–2.77, respectively). Jewish females had significantly higher rates of invasive breast cancer (RR = 2.25, 95 % CI = 1.55–3.25), in situ cervical cancer (RR = 4.01, 95 % CI = 1.27–12.66) and lung cancer (RR = 3.22, 95 % CI = 1.12–9.24) compared to Druze females. We thus observed lower cancer rates among Druze versus Arab and Jewish populations in Israel. A reason for these differences may be due to different nutritional habits. Druze still keep a less processed nutritional lifestyle, than is common in industrial society. There may also be other reasons that have not been identified yet.  相似文献

This article must be considered within the framework of research on distributive justice in the organisational context (Adams, 1965; Deutsch, 1975; Colquitt and Jackson, 2002). The aim is to propose an analysis from a political point of view of the orientation towards equity and equality rules. We take as a starting point the model of political decision in the organisational context by Murphy and Cleveland (1995). The political approach postulates that one cannot pertinently give an account of the managers’ decision modes without locating them in their daily context of human relations management, and their management strategy. We will examine the links between the context of immediate management and the managers’ choices for equity or equality. The results of two studies will be presented. They tend to legitimate the relevance of this approach.  相似文献

Cette recherche élargit à un contexte africain avec la problématique suivante les études en cours sur les relations entre les générations et les valeurs attribuées aux enfants: dans quelle mesure la structure des valeurs projetées sur les enfants (VOC) repérée dans des études antérieures peut‐elle être retrouvée en Afrique du Sud et quelles sont les préférences des femmes concernant la taille des familles petite, nombreuse et idéale. L’échantillon était constitué de trois cohortes de femmes noires sud‐africaines originaires de la province de Limpopo. Des analyses factorielles ont montré que les dimensions de la VOC apparue en Afrique du Sud étaient un agrégat de différentes valeurs. Ont été isolées comme dimensions relatives au désir d’enfants Social/Emotionnel et Traditionnel/Utilitaire. Pour ce qui est des motifs expliquant le choix de ne pas avoir d’enfants sont apparus l’enfant comme source de contraintes et les contraintes que constitue le fait d’avoir un enfant. Les comparaisons entre les générations montrent des variations dans l’importance des dimensions des valeurs accordées aux enfants et dans les préférences concernant la taille de la famille. Les valeurs dont les enfants sont porteurs pour les jeunes mères étaient liées au nombre d’enfants que ces femmes avaient et à leurs préférences relatives à la taille de la famille. La discussion sur les résultats tient compte de l’évolution du contexte sociopolitique de l’Afrique du Sud. This study extends the ongoing studies on values of children and intergenerational relations into an African context with the following key questions: To what extent can the structure of values of children (VOC) identified in previous studies be found in South Africa and what are women's preferences regarding the size of small, large, and ideal families? The sample consisted of three cohorts of Black South African women from the Limpopo Province. Factor analyses showed that the dimensions of VOC found in South Africa are a conglomeration of different values. Identified dimensions were Social/Emotional and Traditional/Utilitarian with respect to reasons for wanting children. Regarding reasons for not wanting children, Child as Source of Constraints and Constraints to Have a Child were identified. Intergenerational comparisons showed variations in the importance of value of children dimensions and in preferences regarding family size. Values of children of younger mothers were related to the number of children these women had and to their preferences regarding family size. The findings are discussed within the changing socio‐political context of South Africa.  相似文献

The brain–computer interface (BCI) provides users with the possibility of sending messages and commands to the external world without using their muscles, thus enabling communication to occur independent of movement. Such a possibility is of utmost importance for paralyzed patients who may otherwise lose their ability to communicate. Enhanced methodology and the development of faster computers have substantially improved applications and offer new possibilities in this field. To date, there have been over 20 BCI research groups working on different approaches. In this paper, we review our studies of BCI based on electric and metabolic activity of the brain.  相似文献
