作为一种规范学科的信息伦理学

在信息伦理学领域 ,存在着两种不同的研究取向 :有些学者将信息伦理学作为一门非规范的伦理学来研究 ,而另一些学者则偏重于信息伦理学的规范性质。信息伦理学作为一门规范学科 ,应当研究不同类型的信息活动中已经存在或可能发生的伦理问题 ,而不能成为计算机伦理学、媒体伦理学、生物信息伦理学、网络伦理学的集装箱。规范的信息伦理学可以参考义务论、美德论、效果论的分析框架 ,而且要综合运用多种学科的方法。各国的信息伦理学有本土化的问题 ,但在全球性的信息沟通中 ,应当实现不同的信息伦理学的整合。     

系列项目时间和空间信息学习的分组效应研究

运用顺序回忆方法考察分组对系列项目时间和空间信息学习的影响。包括两个实验,实验一考察简化时间上的分组,或事先告知被试分组规则的情况下,分组是否会有助于时间顺序信息的学习。结果发现,这两个操作对时间顺序信息学习的促进作用不显著。实验二考察了垂直维度上不同形式的分组对空间位置信息学习的影响。结果发现,不同的分组方式对空间位置信息学习所起的作用不同。本研究支持了时间和空间两类顺序信息学习的内在过程不同,不应该用同一理论机制进行解释。     

信息在人类中传递处理的特点和其进化上的意义

人类信息在世代之间传递有两种途径:一种是依靠遗传,一种是通过非遗传的途径。遗传信息主要靠遗传基因来携带和传递,对个体的生存和延续是最重要的。而非遗传信息主要靠感觉和学习来获得,这种籍传媒的信息获取可能在人类中才具有。为何在生物进化上,要采用这种先天遗传,后天习得,这种两条腿走路的方式来在传布信息呢?目前尚没有一个合理的解释。在本文中我们分别就这两个方面发展进行论述。     

Knowing that strawberries are red and seeing red strawberries: the interaction between surface colour and colour knowledge information

This study investigates the interaction between surface and colour knowledge information during object recognition. In two different experiments, participants were instructed to decide whether two presented stimuli belonged to the same object identity. On the non-matching trials, we manipulated the shape and colour knowledge information activated by the two stimuli by creating four different stimulus pairs: (1) similar in shape and colour (e.g. TOMATO–APPLE); (2) similar in shape and dissimilar in colour (e.g. TOMATO–COCONUT); (3) dissimilar in shape and similar in colour (e.g. TOMATO–CHILI PEPPER) and (4) dissimilar in both shape and colour (e.g. TOMATO–PEANUT). The object pictures were presented in typical and atypical colours and also in black-and-white. The interaction between surface and colour knowledge showed to be contingent upon shape information: while colour knowledge is more important for recognising structurally similar shaped objects, surface colour is more prominent for recognising structurally dissimilar shaped objects.     

The contribution of early auditory and visual information to the discrimination of shot power in ball sports

ObjectiveIt is well-established that early visual information has an important role in human ability to play ball sports, as its correct interpretation promotes accurate predictions concerning the ball motion. Other research highlights that auditory information provides relevant cues in various sport situations. The present study combines these two lines of research with the aim to investigate the contribution of early auditory and visual information to the discrimination of shot power in sport-specific situations.DesignTwo experiments were run, one concerning soccer penalty kicks and the other concerning volleyball smashes. In both experiments there were three conditions: Audio, Audiovideo, and Video; a within subjects design was used, with the three conditions carried out in three different days and in a counterbalanced order among participants.MethodParticipants’ task was to discriminate the power of two penalties/smashes presented in rapid sequence, on the basis of a two-alternative forced choice paradigm.ResultsThe results revealed that, for both penalties and smashes, response accuracy was above chance level in all the three conditions; moreover, while for the penalties no difference among the conditions was observed, for the smashes participants were more accurate in the Audio and Audiovideo conditions compared to the Video condition. As concerns the response times, for both penalties and smashes participants were faster in the Audio and Audiovideo conditions compared to the Video condition.ConclusionsTaken together, the results suggest that the discrimination of shot power was more easily performed on the basis of early auditory information than on the basis of the respective visual information.     

Processing of indexical information requires time: Evidence from change deafness

In three experiments, the efficiency in detecting fear-relevant and fear-irrelevant visual stimuli are compared. A visual search paradigm is used where participants are presented with matrices of different sizes (4 objects/9 objects) and must determine whether all objects are taken from the same category or whether there is a discrepant one. Results from all experiments were consistent with the threat-superiority effect. Participants were quicker when the target was threatening than when it was not. Other indicators confirmed that the detection of threatening targets involves more efficient processes (reduced slopes, absence of position effects). A crucial aspect of these experiments was the comparison of evolutionary-relevant (snakes, spiders, etc.) and modern (guns, syringes, etc.) threats. The threat-superiority effect was repeatedly found for both types of target. Stronger effects were sometimes observed for modern than for evolutionary-relevant threats. The implications for evolutionary explanations of the effect of fear on visual attention are discussed.

Quality and readability of internet information about stuttering

PurposeWe examined the quality and readability of English-language Internet information about stuttering and evaluated the results considering recommendations by experts in health literacy.MethodA search of Internet websites containing information about stuttering was conducted. Three key words (i.e., stuttering, stammering, speech disfluency) were entered into five country-specific versions of the most commonly used Internet search engine. A total of 79 websites were assessed. Their origin (commercial, non-profit, government, personal or university), quality [Health On the Net (HON) certification and DISCERN scores], and readability [Flesch Reading Ease (FRE) score, Flesch-Kincaid Grade Level Formula (F-KGL), and Simple Measure of Gobbledygook (SMOG)] were assessed.ResultsOf the 79 websites, 38 % were of commercial, 42 % were of nonprofit organization, 15 % were of government and 5% were of university origins, respectively. Only 13 % had obtained HON certification and the mean DISCERN scores was 3.10 in a 5-point scale. The mean reading grade levels were at 13th and 14th grade and 100 % of the websites exceeded the recommended 5th to 6th reading grade level for health information.ConclusionsThe quality of Internet-based health information about the treatment of stuttering is generally adequate, but actual usability of the sites examined in this study may be limited due to poor readability levels. This is problematic in persons with poor literacy skills. Since the Internet can be readily accessed as a valuable consumer information resource, speech-language pathologists and other healthcare professionals have an opportunity to direct consumers to websites that provide readable information of good quality.

The natural history of information processors

By spanning the traditional scientific theories in the search for an epistemological home for information it is found that Physics (together with some inputs from Automata Theory) provides the criteria to identify the universals that characterize information processors. It is well known, however, that Physics and Mathematics alone are insufficient to answer some fundamental questions that arise in further speculations on the subject of information. It seems that Biology, in the realm of Evolution Theory and in terms of Natural Selection, is at present the only place able to offer the objective context required to properly characterize information as an object of scientific inquiry.

In this communication we intend to show, by establishing a working equivalence between the epistemological questions that should characterize a theory of information and those questions that characterize the science of Biology, how a science of information can be more objectively characterized. It is only by referring to selective pressures that we can solve the otherwise unanswerable philosophical question of whether it is possible to know if two players of a game are, in fact, playing the same game (the semantic question). It is also shown that it is possible, by using conventional criteria, to establish a phylogenesis of information processors from where we conclude that every information processor now existing in the universe (even computers and robots) has an ancestor that has once been a living being.

It is here suggested, however, that Biology is only a provisory epistemological ground for laying the foundations of an information science. A more inclusive theory should be founded on a generalization of the Theory of Evolution where mutation and natural selection should be described, not in terms of the characteristic media and mechanisms of biological systems, but of the identified universals of information processors.

Information-Hierarchical Organization of Natural Systems I: The Information-Physical Principle

The mathematical notion of information characterizing system organization as such has been developed. The information-physical principle, which characterizes an information exchange in natural hierarchical systems and has been confirmed by its numerous applications, is laid down. It is shown to be based on the ancient “matter–measure–information” concept of physical world structure and talked about in the Hermes Trismegistus's will.
