The rhetoric of the reasoned social scientific fact

An analysis is provided for one possible practical link between rhetorical and social scientific inquiry. That link is found in the rhetoric of the reasoned social scientific fact. Understanding this point of intersection involves grounding a rhetorical theory of how to create and to evaluate arguments (a rhetorical theory of invention and judgment) in the practical problems that confront contemporary social scientists during their efforts to construct reasoned social facts. The applicability of this invention and judgment framework to analysis of the rhetoric of social science is illustrated with reference to a controversy over the legitimacy of rules theoretic explanations of human communication processes. Implications of the practical link between rhetorical and social scientific inquiry are then drawn out.     

Pluralism, scientific knowledge, and the fallacy of overriding values

The paper examines one implication of pluralism, the view that all values are conditional and none are overriding. This implication is that since scientific knowledge is one of the conditional values, there are circumstances in which the pursuit of even the most basic scientific knowledge is legitimately curtailed. These circumstances occur when the pursuit of scientific knowledge conflicts with moral and political values which, in that context, are more important than it. The argument focuses on the case for and against space exploration in search of intelligent extraterrestrial life. The widely held supposition that search for pure scientific knowledge cannot be reasonably curtailed is identified as the fallacy of overriding values.     

知识划界、追赶焦虑与中国本土心理学的理论建构导向

科学心理学以方法为中心的知识建构策略,内在地要求它与常识心理学划界以谋求自然科学分支的学科地位,其代价是对人类心理之情感与意义维度的隔离。在移植西方心理学体系的过程中,科学心理学的争议也内含于中国心理学的发展轨迹中,同时还附加了学术边陲地区特有的学科追赶焦虑。中国本土心理学理论应突破科学至上的观念束缚,致力于发展具有现实解释力和价值引导力的人文主义导向的心理学理论,以切实解决中国现实社会中的心理问题,并在世界心理学界发出真正的中国声音。     

Speaker knowledge influences the comprehension of pragmatic inferences

Inferring what speakers mean from what they say requires consideration of what they know. For instance, depending on the speaker's level of expertise, uttering Some squirrels hibernate can imply that not all squirrels hibernate, or it might imply the weaker proposition that the speaker does not know whether all squirrels hibernate. The present study examines the extent to which speaker knowledge influences implied meanings as well as the timing of any such influence. Using a self-paced presentation, participants read sentences containing some in contexts where a speaker should know whether all was true, or where the speaker merely might know whether all was true. This knowledge manipulation was found to have immediate and reliable effects on the type of inference that was drawn. In contrast, knowledge played no role when the same meanings were conveyed literally. This work thus demonstrates that perceivers consider the speaker's knowledge state incrementally to establish the speaker's communicative goals.

The acquisition of scientific knowledge: the influence of methods of questioning and analysis on the interpretation of children's conceptions of the earth

Studies of children's knowledge of the Earth have led to very different conclusions: some appear to show that children construct their own, non‐scientific ‘theories’ (mental models) of the flat, hollow or dual Earth. Others indicate that many young children have some understanding of the spherical (scientific) Earth, and that their knowledge lacks the coherence of mental models. The reasons for these contrasting views were tested by interviewing French children (N = 178) aged 5–11 years and varying the different methods used in previous research, namely the types of questions (open and forced‐choice), the form of representation (two‐dimensional pictures and three‐dimensional models), and the method of analysis (the mental model theorists' coding scheme and a statistical test for associations using MANOVA). Forced‐choice questions resulted in higher proportions of scientific answers than open questions, and children appeared to have naïve mental models of the Earth only when the mental model theorists' coding scheme was used. These findings support the view that children tend to have ‘fragments’ of scientific knowledge, and that naïve mental models of the Earth are methodological artifacts.

The threshold model of scientific change and the continuity of scientific knowledge

The continuity thesis of the Pozna school threshold model of the growth of scientific knowledge is considered in the light of the example of Van der Waals' and Boyle-Mariotte's laws. It is argued — using both traditional logical means and the structuralist reconstruction of the example — that the continuity thesis does not hold.A distinction between a historical and a systematic point of view is introduced and it is argued that the continuity thesis of the threshold model presupposes the systematic point of view. However, looking at matters from the systematic point of view need not yield the original theory, looked at from the historical point of view. Applied to the case of Van der Waals/Boyle-Mariotte laws, it turns out that the latter law is not a true idealizing special case of the former, contrary to the continuity thesis.     

The morality of scientific openness

The ideal of scientific openness — i.e. the idea that scientific information should be freely accessible to interested parties — is strongly supported throughout the scientific community. At the same time, however, this ideal does not appear to be absolute in the everyday practice of science. In order to get the credit for new scientific advances, scientists often keep information to themselves. Also, it is common practice to withhold information obtained in commissioned research when the scientist has agreed with his or her employer to do so. The secrecy may be intended for ever, as in the military area, but also temporarily until a patent application has been made. The paper explores to what extent such secrecy is undesirable, as seems to be suggested by the ideal of scientific openness. Should this ideal be interpreted as having certain exceptions which make the above-mentioned practices acceptable? Are there, on closer inspection, good arguments for the ideal of scientific openness, and for officially upholding it? Possible versions of the ideal of scientific openness are explored and the issue is found to be rather complex, allowing for wide variations depending on the acting parties, beneficiaries, types of information and moral requirements involved. We conclude that the arguments usually given in favour of this ideal are weaker than what seems to be generally believed, and that, on closer inspection, they leave plenty of room for exceptions to it. These exceptions only partly cover the actual practice of withholding scientific information, and there may still be good reason to advocate, teach and enforce the ideal of scientific openness within the scientific community.

科学隐喻的方法论意义

The essential significance of scientific metaphor lies in applying the general metaphorical theory to specific interpretations and elaborations of scientific theories to form a methodology of scientific explanation. It is a contextual grasp of objective reality. A given metaphorical context and its grasp of the essence of reality can only be valid when the context is continually restructured. Taking the context as a whole, the methodological characteristic of scientific metaphor lies in the unity of understanding and choice, experience and concepts, semantic structures and metaphorical domains, rationality and irrationality. As a form of thinking based on reasons, scientific metaphor plays an important role in invention, representation, explanation, evaluation, and communication.

The development of scientific knowledge of the Earth

Investigation of children's knowledge of the Earth can reveal much about the origins, content and structure of scientific knowledge, and the processes of conceptual change and development. Vosniadou and Brewer (1992 , claim that children construct coherent mental models of a flat, flattened, or hollow Earth based on a framework theory and intuitive constraints of flatness and support. To examine this account, 62 children, aged 5–10 years, and 31 adults ranked 16 pictures according to how well they were thought to represent the Earth. Even young children showed scientific knowledge of the shape of the Earth. There was little or no evidence of naïve mental models, indicating that any intuitions or constraints must be very weak. Instead, before they acquire the scientific view, children's knowledge of the Earth appears to be incoherent and fragmented.     

The effect of knowledge and context in the elicitation of inferences in class-inclusion reasoning

Abstract

Two experiments were carried out with adult subjects to investigate the conditions of production of inferences in a problem-solving task involving reasoning about class inclusion. We tested the hypothesis that the production of appropriate inferences is facilitated whenever pieces of information are stored in memory that can be matched at least in part with the conclusion resulting from the inference. In Experiment 1, problems involving the same inferential pattern but belonging to three different domains were compared. The inclusion relations were of the type “is a kind of” (semantic domain), “more than” (being 8 years old is being more than 7 years old: logico-mathematical domain) or “what I have received on a given day is a part of what I have in the evening” (possession domain). In the semantic domain, the critical inference may be facilitated by the semantic network of concepts stored in memory. In the logico-mathematical domain, there is no information that corresponds to the critical inference, so that inferences have to be elaborated merely by use of general knowledge about the meaning of the relation. The possession domain is an intermediate case, since the inference corresponds to knowledge about relations in the possession domain. The results clearly support a memory-cueing hypothesis: There is a marked order of difficulty ranging from the logico-mathematical domain (most difficult) to the semantic domain (least difficult). In Experiment 2, equivalent problems using the same conceptual information were compared: The critical inference involved scanning a series of numbers either in direct order (more than 7 is 8, 9, 10) or in reverse order (8, 9, 10 is more than 7). The number of correct solutions was higher and the response latency much shorter for those problems in which the critical inference was of the type “more than 7 is 8, 9 or 10″.     

Effectiveness of research guidelines in prevention of scientific misconduct

In response to a series of allegations of scientific misconduct in the 1980’s, a number of scientific societies, national agencies, and academic institutions, including Harvard Medical School, devised guidelines to increase awareness of optimal scientific practices and to attempt to prevent as many episodes of misconduct as possible. The chief argument for adopting guidelines is to promote good science. There is no evidence that well-crafted guidelines have had any detrimental effect on creativity since they focus on design of research studies, documentation of research findings, assignment of credit through authorship, data management and supervision of trainees, not on the origin and evolution of ideas. This paper addresses a spectrum of causes of scientific misconduct or unacceptable scientific behavior and couples these with estimates of the potential for prevention if guidelines for scientific investigation are adopted. The conclusion is that clear and understandable guidelines should help to reduce the chance that flawed research will escape from our institutions. However, they cannot be relied upon alone to prevent all instances of scientific misconduct and should be regarded rather as one means of bolstering the integrity of the entire scientific enterprise.     

Examining the influence of anecdotal stories and the interplay of individual differences on reasoning

In two experiments, we explored whether anecdotal stories influenced how individuals reasoned when evaluating scientific news articles. We additionally considered the role of education level and thinking dispositions on reasoning. Participants evaluated eight scientific news articles that drew questionable interpretations from the evidence. Overall, anecdotal stories decreased the ability to reason scientifically even when controlling for education level and thinking dispositions. Additionally, we found that article length was related to participants' ratings of the news articles. Our study demonstrates that anecdotes can discourage scientific reasoning while also pointing to the potential influence of article length on judgements of quality.     

The effects of prior knowledge and text structure on comprehension processes during reading of scientific texts

The aim of the present study was to investigate the effects of prior knowledge and text structure on cognitive processes during comprehension of scientific texts. To investigate the processes online, we used a think-aloud methodology in Experiment 1 and a reading time methodology in Experiment 2. In both experiments, we obtained offline comprehension measures and measures of individual differences in working memory and need for cognition. Across the two experiments, the results indicated that readers adjust their processing as a function of the interaction between prior knowledge and text structure. In particular, adjustments in theactual processes that take place during reading were observed for readers who had erroneous prior knowledge,but only when they read a text that was structured to explicitly refute this prior knowledge. Furthermore, the results showed that readers' memory for the text was affected by differences in their prior knowledge, independently of text structure. These findings contribute to our understanding of the relation between different factorsthat are associated with comprehension of scientific texts and have implications for theories of comprehension and conceptual change.     

Narrative rationality and the logic of scientific discourse

This essay argues that scientific discourse is amenable to interpretation and assessment from the perspective of the narrative paradigm and its attendant logic, narrative rationality. It also contends that this logic entails a revised conception of knowledge, one that permits the possibility of wisdom. The text analyzed is James D. Watson and Francis H. Crick's proposal of the double helix model of DNA.
