Cultural illiteracy and the Internet.   总被引:1,自引:0,他引:1  
The Internet has created different expectations regarding its possibilities as a tool for including groups that have heretofore been excluded from the modern world. But mere access to information does not necessarily imply correct and effective use of it. Despite the great increase in Internet access in previously excluded areas, expectations of inclusion have not been fulfilled. Research suggests that the effectiveness of Internet use varies among cultures, but all such studies analyze countries as a whole with no further breakdown. Yet it is known that within a given country there co-exist subcultures that differ both in language and social context. This paper presents a study that shows the correlation between different social subcultures and their Internet knowledge.  相似文献

The aims of this study were twofold. On the one hand, to reach an understanding of, and to illustrate the experience of addictive buying and, on the other, to throw some light on the controversial subject of addicts' personal responsibility for their behavior. With these aims, a thematic analysis of an extensive diary written by a compulsive buyer is presented. Four themes emerge from the analysis: the defining characteristics of addiction to buying that determine the boundary separating it from other forms of impulsive or careless buying; several causal factors; the role that money and material objects play in family relationships and friendships through the symbolic meanings they adopt; and the relationship of personal values with impulsiveness and self-control. In view of the results, the moral model of addiction to buying is discussed, and an explanatory model of the ambivalence that is characteristic of addiction to buying is proposed, based on a personal hierarchy of values.  相似文献

The objective of the current study was to compare the performance of schizophrenic patients and normal controls on implicit memory tests. Two neuropsychological tasks were administered to 29 patients and normal participant samples. The implicit tests were: Word fragment completion and Word production from semantic categories. The priming score was the variable of interest. Priming effects are obtained in normal subjects and schizophrenia patients, regardless of the implicit test used. However, a dissociation in priming between normal and patient groups was observed, depending on the test used. For word fragment test, priming was identical between the two groups. However, for word production, priming obtained in schizophrenics was lower than priming in normal controls. Results confirm a dissociation effect in implicit memory tests. These results could be explained in the context of the Roediger and Blaxton (1987) distinction between data-driven and conceptually-driven processing. This evidence suggests that a complete neuropsychological assessment of memory in schizophrenia should include different kinds of implicit memory tests (procedural, perceptual, and conceptual tasks).  相似文献

The aim of this study was to translate into Spanish and to validate the Rosenberg Self-Esteem Scale (RSES), completed by 420 university students. Confirmatory factor analysis revealed that the model that best fit the data, both in the total sample and in the male and female subsamples, was the one-factor structure with method effects associated with positively worded items. The results indicated high, positive correlations between self-esteem and the five dimensions of self-concept. The scale showed satisfactory levels of internal consistency and temporal stability over a four-week period. Lastly, gender differences were obtained. These findings support the use of the RSES for the assessment of self-esteem in higher education.  相似文献

This study focuses on the mediator role of social comparison in the relationship between perceived breach of psychological contract and burnout. A previous model showing the hypothesized effects of perceived breach on burnout, both direct and mediated, is proposed. The final model reached an optimal fit to the data and was confirmed through multigroup analysis using a sample of Spanish teachers (N = 401) belonging to preprimary, primary, and secondary schools. Multigroup analyses showed that the model fit all groups adequately.  相似文献

Human experience of temporal durations exhibits a multi-regional structure, with more or less distinct boundaries, or horizons, on the scale of physical duration. The inner horizons are imposed by perceptual thresholds for simultaneity (approximately equal to 3 ms) and temporal order (approximatly equal to 30 ms), and are determined by the dynamical properties of the neural substrate integrating sensory information. Related to the inner horizon of experienced time are perceptual or cognitive "moments." Comparative data on autokinetic times suggest that these moments may be relatively invariant (approximately equal to 10(2) ms) across a wide range of species. Extension of the "sensible present" (approximately equal to 3 s) defines an intermediate horizon, beyond which the generic experience of duration develops. The domain of immediate duration experience is delimited by the ultimate outer horizon at about = 10(2) s, as evidenced by analysis of duration reproduction experiments (reproducibility horizon), probably determined by relaxation times of "neural accumulators." Beyond these phenomenal horizons, time is merely cognitively (re)constructed, not actually experienced or "perceived," a fact that is frequently ignored by contemporary time perception research. The nyocentric organization of time experience shows an interesting analogy with the egocentric organization of space, suggesting that structures of subjective space and time are derived from active motion as a common experiential basis.  相似文献

Individuals with autism frequently show impairments in text reading comprehension. This often is attributed to poor ability to draw inferences during reading and to inadequate access to relevant knowledge. The current study tested this hypothesis by measuring the time taken to read the same question, relating to either physical or social world knowledge, when it was either relevant or irrelevant to the bridging inference evoked by a preceding two-sentence vignette. In the study, 16 normally developing adolescents and 16 adolescents with autism were matched on word reading accuracy, chronological age, and vocabulary but differed significantly in text comprehension. A strong priming effect was found, robust over participants and over items; participants read those questions that were relevant to the inference evoked by the vignette faster than they read those questions that were irrelevant, and no interaction with group membership or type of knowledge was found. This indicates that readers with autism, just like controls, were activating appropriate world knowledge primed by implicit inferences while reading the vignettes. Thus, the comprehension problems in these readers cannot be attributed to an inability to make implicit inferences or to draw on relevant world knowledge. Instead, we suggest that these problems must be sought at a higher level of text processing.  相似文献

We investigated the dimensionality of the French version of the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965) using confirmatory factor analysis. We tested models of 1 or 2 factors. Results suggest the RSES is a 1-dimensional scale with 3 highly correlated items. Comparison with the Revised NEO-Personality Inventory (NEO-PI-R; Costa, McCrae, & Rolland, 1998) demonstrated that Neuroticism correlated strongly and Extraversion and Conscientiousness moderately with the RSES. Depression accounted for 47% of the variance of the RSES. Other NEO-PI-R facets were also moderately related with self-esteem.  相似文献
