An experimental study was conducted to investigate the impact of violent computer games on state hostility, state anxiety and arousal. Participants were undergraduate students, aged from 18 to 25 years. Before the experimental sessions, participants filled in self‐report measures concerning their video game habits and were also pre‐tested for aggressiveness and trait anxiety. Physiological responses (heart rate and skin conductance) were measured during the experiment. After playing, information about state hostility and state anxiety was collected. The results showed that participants who played the violent game reported significantly higher state hostility, and support the assumption that an aggressive personality moderates the effect of playing a violent game on state hostility.

The main purpose of this study was to test the Sport Commitment Model in young soccer players. Participants' ( N = 437) age ranged from 14 to 16 years. Based on the sport commitment model proposed by Scanlan and colleagues, 6 scales and 28-items constitute the Sport Commitment Questionnaire (SCQ). Results of this study provide some support for the reliability and validity of the SCQ, using a sample of young soccer players. Reliability analysis provided acceptable internal consistency for four scales: Sport Commitment, Sport Enjoyment, Involvement Alternatives and Social Constraints. Sport Enjoyment (Beta= .56, p <.001) and Involvement Alternatives (Beta= -.40, p <.001) were the strongest sport commitment predictors. Further studies with a broader age range, different genders, and other sports or competitive levels are required to continue analyzing the sport commitment model. 相似文献

The aim of this work was to teach the discrimination of "equal" and "different" in numbers. The experiment was carried out a seven-year-old child with intellectual disability. The problem was analysed from the contextual control perspective. The learning procedure consisted of explicitly teaching a second-order conditional discrimination, and transfer to a novel second-order conditional discrimination was tested. In this study, the boy learned that, in presence of X1 (equal), he had to select the comparison B1 (the number one), given the sample A1 (the word one) and B2 (the number two), given A2 (the word two). He also he learned that, in the presence of X2 (different), he had to select the comparison B2 (the number two), given the sample A1 (the word one) and B1 (the number one), given A2 (the word two). We subsequently presented the contextual stimuli with two new numbers: three and four. The results showed the occurrence of learning transfer without explicit training in the new numbers. 相似文献

The self-reporting of cancer history is becoming increasingly important, as it frequently guides medical decision-making.
We studied the accuracy of personal cancer history using a self-administered questionnaire, comparing the results with the
Tumor Registry at our institution. Among 39,662 records, we identified 3614 women with a single cancer in the Tumor Registry
who reported none or one cancer on their questionnaire. The sensitivity in self-reporting cancers was 85.7%, ranging from
92.1% for breast cancer to 42.9% for leukemia. The accuracy for breast cancer and Hodgkin's Lymphoma was significantly better
than other cancers (p=0.00027, CI: 1.4–3.88). Analysis of patient's characteristics showed that Caucasians reported breast cancer more accurately
than Asian/Pacific Islanders (p=0.008), and those with Jewish ancestry more accurately than non-Jewish (p=0.0435). These results will help us to improve data collection and thus improve medical decision-making. 相似文献

This article compiles the investigations carried out by a Research Group of the University of Granada, Spain. Its different
projects on writing’s cognitive social and cultural processes have been supported by the Spanish Government. This line of
research joined together linguistic, psychological, social and cultural contributions to the development of writing from the
1970s. Currently, this line of research develops in collaboration with other European Universities: (a) Interuniversity Centre
for Research On Cognitive Processing in Natural and Artificial Systems (ECONA), “La Sapienza” University of Rome (Italy);
(b) Anadolu University, (Eskisehir, Turkey); (c) Coimbra University (Portugal); (d) University of Zaragoza (Spain); (e) the
Institute of Education of the University of London (United Kingdom). The aforementioned collaboration is materializing into
projects like the International Master on Multilingual Writing: Cognitive, Intercultural and Technological Processes of Written
Communication () and the International Congress: Writing in the twenty-first Century: Cognition, Multilinguisim and Technologies, held in
Granada (). This research line is focussed on the development of strategies in writing development, basic to train twenty-first century
societies’ citizens. In these societies, participation in production media, social exchange and the development of multilingual
written communication skills through new computer technologies spread multicultural values. In order to fulfil the social
exigencies, it is needed to have the collaboration of research groups for designing and applying international research projects.

Chile’s General Law of Education states that one of the purposes of education is the spiritual development of all its schooled population. Furthermore, guidelines in Chile’s education system place school directors as key players in student’s learning. This article presents the results of a research involving school directors from Valparaíso, Chile. The aim of this research was to identify how directors of secular and religious schools understand their students’ spiritual development. We studied this aspect in particular through semi-structured interviews conducted with 20 participants. Results show that directors understand spirituality as a typically human ability that can be strengthened in schools and, thus, they believe it to be highly important in schools. In addition, they see a strong relation between spiritual development and ethical and moral development. This study also shows differences in how secular and religious schools’ directors understand this relation. This opens the way for more in-depth analysis regarding spiritual development in Chile’s education system, especially considering that directors generally believe it to be a part of a holistic and quality education. 相似文献

Variation in intracellular calcium concentration regulates the induction of long-term synaptic plasticity and is associated with a variety of memory/retrieval and learning paradigms. Accordingly, impaired calcium mobilization from internal deposits affects synaptic plasticity and cognition in the aged brain. During taste memory formation several proteins are modulated directly or indirectly by calcium, and recent evidence suggests the importance of calcium buffering and the role of intracellular calcium deposits during cognitive processes. Thus, the main goal of this research was to study the consequence of hampering changes in cytoplasmic calcium and inhibiting SERCA activity by BAPTA-AM and thapsigargin treatments, respectively, in the insular cortex during different stages of taste memory formation. Using conditioned taste aversion (CTA), we found differential effects of BAPTA-AM and thapsigargin infusions before and after gustatory stimulation, as well as during taste aversive memory consolidation; BAPTA-AM, but not thapsigargin, attenuates acquisition and/or consolidation of CTA, but neither compound affects taste aversive memory retrieval. These results point to the importance of intracellular calcium dynamics in the insular cortex during different stages of taste aversive memory formation. 相似文献
