Two experiments were used to assess the efficacy of the keyword mnemonic method in adults. In Experiment 1, immediate and delayed recall (at a one-day interval) were assessed by comparing the results obtained by a group of adults using the keyword mnemonic method in contrast to a group using the repetition method. The mean age of the sample under study was 59.35 years. Subjects were required to learn a list of 16 words translated from Latin into Spanish. Participants who used keyword mnemonics that had been devised by other experimental participants of the same characteristics, obtained significantly higher immediate and delayed recall scores than participants in the repetition method. In Experiment 2, other participants had to learn a list of 24 Latin words translated into Spanish by using the keyword mnemonic method reinforced with pictures. Immediate and delayed recall were significantly greater in the keyword mnemonic method group than in the repetition method group. 相似文献

In Higher Education, performance and Teaching-Learning (T-L) contexts are highly current concerns. Based on the DEDEPRO model, interdependence can be established between instructional contexts and levels of performance as they relate to the T-L process. Partitipants were 2020 pupils from two Spanish universities. Measurements of both variables were used in a quasi-experimental and correlational design. The univariate and causal analyses showed the effect of context on the T-L process and on performance; thus, the interdependent relationships between the latter and perception of the T-L process. Partial interaction effects also appeared, as well as a causal model of academic performance. Results are discussed and implications for the ECTS (European Credit Transfer System) are analyzed. 相似文献

We conducted a content analysis of online job application forms used by companies listed on the Spanish Stock Exchange (i.e., Bolsa de Madrid). We collected data from 76 companies in 2005 and then again for 66 of these companies in 2009. We coded the type of information required on the application forms based on 24 categories related to potential illegal discrimination and personnel selection social context issues (i.e., fairness, intrusiveness, and privacy). Results indicated that the relative frequency of the 24 information categories has remained stable from 2005 to 2009. Moreover, averaging 2005 and 2009 results, a large percentage of companies require information that can be used for illegal discrimination and can be perceived as unfair, intrusive, and invasive of applicants' privacy such as age or date of birth (87%), nationality (61%), marital status (48%), place of birth (57%), passport number (47%), a photograph (23%), and number of children (11%). Our results document a science–practice gap in e‐recruitment because scholarly research suggests that requesting these types of information leads to negative applicant reactions ranging from negative perceptions and emotions to actually initiating legal action against the recruiting firm. Our results also point to e‐recruitment as an area that could be targeted as a good collaboration topic between scientists and practitioners because the resulting research has the potential to make important contributions toward bridging the science–practice gap. 相似文献

Studies from many languages consistently report that subject relative clauses (SR) are easier to process than object relatives (OR). However, Hsiao and Gibson (2003) report an OR preference for Chinese, a finding that has been contested. Here we report faster OR versus SR processing in Basque, an ergative, head-final language with pre-nominal relative clauses. A self-paced reading task was used in Experiments 1 and 2, while ERPs were recorded in Experiment 3. We used relative clauses that were ambiguous between an object or subject-gap interpretation and disambiguated later in the sentence. The results of Experiments 1 and 2 showed that SR took longer to read than OR in the critical disambiguating region. In addition, Experiment 3 showed that SR produced larger amplitudes than OR in the P600 window immediately after reading the critical disambiguating word. Our results suggest that SR are not universally easier to process. They cast doubts on universal hypotheses and suggest that processing complexity may depend on language-specific aspects of grammar. 相似文献

The objectives of the present study were to adapt and analyze the factor structure, reliability, and validity of the Social Phobia and Anxiety Inventory for Children (SPAI-C; Beidel, Turner, & Morris, 1995) in a Spanish population. The SPAI-C was applied to a sample of 1588 children and adolescents with ages ranging from 10 to 17 years. The confirmatory factor analysis (CFA) showed a four-factor structure: Public performance, Assertiveness, Fear and avoidance/escape in social encounters, and Cognitive and psychophysiological interferences. Internal consistency was high (.90) and test-retest reliability was moderate (.56). Significant differences were found in the variables sex and age, although the effect size was small in both variables and their interaction. Overall, the increase of the age value was inversely proportional to that of social anxiety measured with the SPAI-C; in participants of the same age, values were higher for girls than for boys. Results suggest that the Social Phobia and Anxiety Inventory For Children is a valid and reliable instrument to assess social anxiety in Spanish children and adolescents. 相似文献

This study examined a gratitude intervention repeating Emmons and McCullough study (2003) in a Spanish sample, Participants were randomly assigned to one of three conditions (gratitude, hassles and any event) and kept daily records during 2 weeks of gratitude, affect, quality of relationships, physical and subjective well-being. We added design features to assess the intervention long-term impact (follow-up measures), and to improve the design control (pre-treatment measures). Following the cited authors' analysis, i.e., comparing groups only in the post-test, we replicated their results, finding differences in positive affect and gratitude between the gratitude condition and the hassles condition. However, when including both the pre and the follow-up measures in the analysis, results were replicated only partially, as the difference in gratitude disappeared. Moreover, the difference in positive affect between groups in the post-test seemed to be influenced mainly by a decrease in positive affect in the hassles group. Post-test differences between groups in positive affect disappeared in the follow-up. Gratitude interventions may have an effect on well-being, but we consider other methods to promote gratitude besides gratitude journals should be tested. 相似文献

A course in professional ethics for civil engineers was taught for the first time in Spain during the academic year 2007/08.
In this paper a survey on the satisfaction and expectation of the course is presented. Surprisingly the students sought moral
and ethical principles for their own ordinary lives as well as for their profession. Students were concerned about the law,
but in their actions they were more concerned with their conscience, aware that it can be separate from the law. 相似文献

A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variability among highly suggestible individuals matches the phenomenological profiles predicted by dissociative typological models of high hypnotic suggestibility. Phenomenological state scores indexed in reference to a resting epoch during hypnosis were submitted to a latent profile analysis. The profiles in the derived four-class solution differed in multiple experiential dimensions and hypnotic suggestibility. Highly suggestible individuals were distributed across two classes that exhibited response patterns suggesting an inward attention subtype and a dissociative subtype. These results provide support for dissociative typological models of high hypnotic suggestibility and indicate that highly suggestible individuals do not display a uniform response to a hypnotic induction. 相似文献

A decline in the frequency or intensity of a conditioned behavior following the withdrawal of the reinforcement is called
experimental extinction. However, the experimental manipulation necessary to trigger memory reconsolidation or extinction
is to expose the animal to the conditioned stimulus in the absence of reinforcement. Recovery protocols were used to reveal
which of these two processes was developed. By using the crab contextual memory model (a visual danger stimulus associated
with the training context), we investigated the dynamics of extinction memory in Chasmagnathus. Here, we reveal the presence of three recovery protocols that restore the original memory: the old memory comes back 4 days
after the extinction training, or when a weak training is administered later, or once the VDS is presented in a novel context
24 h after the extinction session. Another objective was to evaluate whether the administration of multi-trial extinction
training could trigger an extinction memory in Chasmagnathus. The results evince that the extinction memory appears only when the total re-exposure time is around 90 min independently
of the number of trials employed to accumulate it. Thus, it is feasible that the mechanisms described for the case of the
extinction memory acquired through a single training trial are valid for multi-trial extinction protocols. Finally, these
results are in agreement with those reports obtained with models phylogenetically far apart from the crab. Behind this attempt
is the idea that in the domain of studies on memory, some principles of behavior organization and basic mechanisms have universal
validity. 相似文献
