We investigate a lattice of conditional logics described by a Kripke type semantics, which was suggested by Chellas and Segerberg – Chellas–Segerberg (CS) semantics – plus 30 further principles. We (i) present a non-trivial frame-based completeness result, (ii) a translation procedure which gives one corresponding trivial frame conditions for arbitrary formula schemata, and (iii) non-trivial frame conditions in CS semantics which correspond to the 30 principles. 相似文献

In research on cognitive plasticity, two training approaches have been established: (1) training of strategies to improve performance in a given task (e.g., encoding strategies to improve episodic memory performance) and (2) training of basic cognitive processes (e.g., working memory, inhibition) that underlie a range of more complex cognitive tasks (e.g., planning) to improve both the training target and the complex transfer tasks. Strategy training aims to compensate or circumvent limitations in underlying processes, while process training attempts to augment or to restore these processes. Although research on both approaches has produced some promising findings, results are still heterogeneous and the impact of most training regimes for everyday life is unknown. We, therefore, discuss recent proposals of training regimes aiming to improve prospective memory (i.e., forming and realizing delayed intentions) as this type of complex cognition is highly relevant for independent living. Furthermore, prospective memory is associated with working memory and executive functions and age-related decline is widely reported. We review initial evidence suggesting that both training regimes (i.e., strategy and/or process training) can successfully be applied to improve prospective memory. Conceptual and methodological implications of the findings for research on age-related prospective memory and for training research in general are discussed. 相似文献

Reference is made to the content determination of the entry term “mental retardation” in the criminal responsibility paragraphs of the Penal Code. The forensic relevance of intellectual disability is low. Forensic effects of retarded ability for reasoning usually fail due to the understanding in question. A diminution of criminal responsibility can if necessary be justified by a reduction in accountability. 相似文献

ABSTRACTThis study investigated whether individuals can predict their future prospective memory (PM) performance in a lab-based task and in a naturalistic task. Metacognitive awareness was assessed by asking participants to give judgments-of-learning (JOLs) on an item-level for the prospective (that something has to be done) and retrospective (what to do) PM component. In addition, to explore whether giving predictions influences PM performance, we compared a control group (without predictions) to a prediction group. Results revealed that giving predictions did not change PM performance. Moreover, participants were underconfident in their PM performance in the lab-based task, while they were overconfident in the naturalistic task. In addition, item-level JOLs indicated that they were inaccurate in predicting what items they will recall or not, but only for the prospective component of the PM task. As for the retrospective component, they were equally accurate in both task settings. This study suggests a dissociation of metacognitive awareness for PM according to both task setting and processing component. 相似文献

Concern is growing as research continues to find evidence of academic misconduct among medical students. There is, however, paucity of information on this issue among medical students and medical graduates in Africa. We determined the perceptions and attitude of house officers on academic misconduct within Nigerian medical schools. We conducted 7 focus group discussions (FGDs) among pre-registration house-officers (PRHOs) working in a Nigerian Teaching hospital between October and November 2013. A FGD guide containing 7 broad questions related to their perception and attitude on academic misconduct was employed. Ethnographic content analysis and manual coding were adopted in identifying themes, issues and representative quotations. A total of 58 participants out of an eligible pool of 76 PRHOs were recruited. All the groups associated academic misconduct chiefly with cheating in examinations, and perceived it as a commonplace problem. “It is a part of school life”, admitted one PRHO. Copying during exam appeared to be the commonest form of cheating. Another respondent opined that “The lecturers should be more concerned with helping students understand better. They should not make passing an exam a do-or-die affair.” The perception and attitudes towards academic misconduct may be a reflection of the prevailing moral decline in the contemporary Nigerian society. Underlying the reasons adduced by the participants for getting involved in academic misconduct is the fear of failure in examinations. Apart from consolidating formal and informal medical ethics education, the medical schools should ensure that the opportunities and pressures to indulge in academic misconduct are minimized. 相似文献

Utilizing technology for automated item generation is not a new idea. However, test items used in commercial testing programs or in research are still predominantly written by humans, in most cases by content experts or professional item writers. Human experts are a limited resource and testing agencies incur high costs in the process of continuous renewal of item banks to sustain testing programs. Using algorithms instead holds the promise of providing unlimited resources for this crucial part of assessment development. The approach presented here deviates in several ways from previous attempts to solve this problem. In the past, automatic item generation relied either on generating clones of narrowly defined item types such as those found in language free intelligence tests (e.g., Raven’s progressive matrices) or on an extensive analysis of task components and derivation of schemata to produce items with pre-specified variability that are hoped to have predictable levels of difficulty. It is somewhat unlikely that researchers utilizing these previous approaches would look at the proposed approach with favor; however, recent applications of machine learning show success in solving tasks that seemed impossible for machines not too long ago. The proposed approach uses deep learning to implement probabilistic language models, not unlike what Google brain and Amazon Alexa use for language processing and generation. 相似文献
