I argue that advocates of moderate epistemic idealization need some standards against which they can determine whether a particular individual P has a responsibility to acquire some specific piece of information α. Such a specification is necessary for the purpose of determining whether a reason R, the recognition of which depends on accounting for α, can legitimately be ascribed to P. To this end, I propose an initial sketch of a criterion that may be helpful in illuminating the conditions (...) in which P might be said to have a responsibility to take α into account when searching for reasons to act or believe. I worry that reason ascriptions that are based on information acquisition expectations which are not captured by this criterion may be open to charges of authoritarianism, especially when such a reason ascription prompts one person to demand that another act in a way that is responsive to the ascribed reason.

News that the first draft of a map of the human genome had been completed was received with great excitement but fears persist about how this knowledge will be used. Such concerns were the basis for an international conference held in Preston, England in December 1997. The issues addressed were non-existent when many of those attending the conference were born, but they are among the most pressing ethical problems we face today. They are philosophically challenging, and the way we deal (...) with them will have far reaching consequences for both individuals and society. The proceedings of the conference are now available in this book. Thirty authors, almost exclusively from Western Europe and North America, have written about the important issues of eugenics, insurance, the effects of market forces and the question of patents, public awareness of genetics and a variety of psychosocial and ethical concerns.

Social networks play a significant role in learning and thus in farmers’ adoption of new agricultural technologies. This study examined the effects of social network factors on information acquisition and adoption of new seed varieties among groundnut farmers in Uganda and Kenya. The data were generated through face-to-face interviews from a random sample of 461 farmers, 232 in Uganda and 229 in Kenya. To assess these effects two alternative econometric models were used: a seemingly unrelated bivariate probit model (...) and a recursive bivariate probit model. The statistical evaluation of the SUBP shows that information acquisition and adoption decisions are interrelated while tests for the RBP do not support this latter model. Therefore, the analysis is based on the results obtained from the SUBP. These results reveal that social network factors, particularly weak ties with external support, partially influence information acquisition, but do not influence adoption. In Uganda, external support, gender, farm size, and geographic location have an impact on information acquisition. In Kenya, external support and geographic location also have an impact on information acquisition. With regard to adoption, gender, household size, and geographic location play the most important roles for Ugandan farmers, while in Kenya information from external sources, education, and farm size affect adoption choice. The study provides insight on the importance of external weak ties in groundnut farming, and a need to understand regional differences along gender lines while developing agricultural strategies. This study further illustrates the importance of farmer participation in applied technology research and the impact of social interactions among farmers and external agents. (shrink)

Several business trends have forced accelerated efforts to acquire competitive intelligence. While coverage of business ethics in classroom instruction has accelerated, concerns over unethical competitive information acquisition strategies persist. The frequency of use by individuals, their companies, and their competitors is assessed, and the findings reveal the extent of this ethics gap.

The aim of this study was to investigate the effect of numeracy and the emotion of fear on the decision-making process. While previous research demonstrated that these factors are independently related to search effort, search policy and choice in a decision from experience task, less is known about how their interaction contributes to processing information under uncertainty. We attempted to address this problem and to fill this gap. In the present study, we hypothesized that more numerate people would sample (...) more information about a decision problem and that the effect of fear would depend on the source of this emotion: whether it is integral (i.e., relevant) or incidental (i.e., irrelevant) to a decision problem. Additionally, we tested how these factors predict choices. We addressed these hypotheses in a series of two experiments. In each experiment, we used a sampling paradigm to measure search effort, search policy and choice in nine binary problems included in a decision from experience task. In Experiment 1, before the sampling task we elicited incidental fear by asking participants to recall fearful events from their life. In Experiment 2, integral fear was elicited by asking participants to make choices concerning medical treatment. Decision problems and their payoff distributions were the same in the two experiments and across each condition. In both experiments, we assessed objective statistical numeracy and controlled for a change in the current emotional state. We found that more numerate people sampled more information about a decision problem and switched less frequently between alternatives. Incidental fear marginally predicted search effort. Integral fear led to larger sample sizes, but only among more numerate people. Neither numeracy nor fear were related to the number of choices that maximized expected values. However, across two experiments sample sizes predicted the number of choices that maximized experienced mean returns. The findings suggest that people with higher numeracy may be more sensitive to integral emotions; this may result in more effortful sampling of relevant information leading to choices maximizing experienced returns.

We investigate whether risky choice framing, i.e., the preference of a sure over an equivalent risky option when choosing among gains, and the reverse when choosing among losses, depends on redundancy and density of information available in a task. Redundancy, the saliency of missing information, and density, the description of options in one or multiple chunks, was manipulated in a matrix setup presented in MouselabWeb. On the choice level we found a framing effect only in setups with non-redundant (...) information. On the process level outcomes attracted more acquisitions than probabilities, irrespective of redundancy. A dissociation between acquisition behavior and choice calls for a critical discussion of the limits of process-tracing measures for understanding and predicting choices in decision making tasks.

We are reviewing and summarizing evidence for the processes of acquisition of information outside of conscious awareness (processing information about covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). A considerable amount of data indicates that as compared to consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but also structurally more sophisticated in the sense that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms (...) of nonconscious acquisition of information provide a major channel for the development of procedural knowledge which is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering emotional reactions.

Information is clearly vital to public health, but the acquisition and use of public health data elicit serious privacy concerns. One strategy for navigating this dilemma is to build 'trust' in institutions responsible for health information, thereby reducing privacy concerns and increasing willingness to contribute personal data. This strategy, as currently presented in public health literature, has serious shortcomings. But it can be augmented by appealing to the philosophical analysis of the concept of trust. Philosophers distinguish trust (...) and trustworthiness from cognate attitudes, such as confident reliance. Central to this is value congruence: trust is grounded in the perception of shared values. So, the way to build trust in institutions responsible for health data is for those institutions to develop and display values shared by the public. We defend this approach from objections, such as that trust is an interpersonal attitude inappropriate to the way people relate to organisations. The paper then moves on to the practical application of our strategy. Trust and trustworthiness can reduce privacy concerns and increase willingness to share health data, notably, in the context of internal and external threats to data privacy. We end by appealing for the sort of empirical work our proposal requires. (shrink)

Across languages of the world, some grammatical patterns have been argued to be more common than expected by chance. These are sometimes referred to as (statistical) language universals. One such universal is the correlation between constituent order freedom and the presence of a case system in a language. Here, we explore whether this correlation can be explained by a bias to balance production effort and informativity of cues to grammatical function. Two groups of learners were presented with miniature artificial languages (...) containing optional case marking and either flexible or fixed constituent order. Learners of the flexible order language used case marking significantly more often. This result parallels the typological correlation between constituent order flexibility and the presence of case marking in a language and provides a possible explanation for the historical development of Old English to Modern English, from flexible constituent order with case marking to relatively fixed order without case marking. In addition, learners of the flexible order language conditioned case marking on constituent order, using more case marking with the cross‐linguistically less frequent order, again mirroring typological data. These results suggest that some cross‐linguistic generalizations originate in functionally motivated biases operating during language learning. (shrink)

Constructions marking information structure in French have been widely documented within the constructionist framework. C’est ‘it is’ clefts have been demonstrated to express the focus of the sentence. Nevertheless, it remains unclear how children are able to acquire clefts, and how they develop information structure categories. The aim of this study is to investigate the acquisition of clefts in French through the usage-based framework, to understand whether IS categories emerge gradually like other linguistic categories, and how children (...) build IS categories. For this, I analysed 256 c’est-clefts produced by three children between age 2 and 3. I show that most early clefts are produced by children with the chunk c’est moi associated with the concrete function of requesting to perform an action themselves. This chunk then becomes a frame with slot, extending the function to other human referents and discourse participants with the function of requesting adults to perform an action. Another large portion of early clefts seems to belong to a frame with slot c’est X whose function is to identify the agent who carried out an action. These findings suggest that the information structure category of focus emerges gradually. (shrink)

An experiment is reported which tests for positive confirmation bias in a setting in which individuals choose what information to buy, prior to making a decision. The design – an adaptation of Wason's selection task – reveals the use that subjects make of information after buying it. Strong evidence of positive confirmation bias, in both information acquisition and information use, is found; and this bias is found to be robust to experience. It is suggested that (...) the bias results from a pattern of reasoning which, although producing sub-optimal decisions, is internally coherent and which is self-reinforcing. (shrink)

In the last few years a lively discussion on information packaging has arisen, where traditional dichotomies Theme/Rheme, Topic/Comment and Focus/Background have been taken up again and partly reinterpreted. The discussion is mainly being held in syntax, but also in the fields of semantics and pragmatics. Some remarkable progress has been made especially in Focus phonology. Even if the role of information conveying and information packaging in the Indoeuropean languages was hinted at as early as in the classical (...) studies of the Neogrammarians, this field has remained neglected in today's historical linguistics. This volume tries to partly cover this lack with a sample of papers which offer a various range of new empirical data analyzed from the point of view of information structure. The novelty of the papers consists in the modern theoretical perspective from which the data are analyzed and in the various phenomena considered, which range from the rise of clitic elements to word order change and verb movement.

The “Chu shuo” 儲說 chapters of the Hanfeizi 韓非 子, attributed to Han Fei 韓非, encompass an extensive collection of anecdotes. The jing 經 sections of these chapters are traditionally understood to be a set of “canonical” teachings, to be explicated by the anecdotes in the shuo 說 sections. Eschewing this assumption, my analysis substantiates an alternative hypothesis that sees many of the jing texts as later superimpositions intended to serve as paratexts to existing anecdotal collections. By interpreting the jing (...) and shuo sections as paratexts and main texts, respectively, this study reveals how early compilers sought to organize and inventory information, as well as to guide future users’ understanding and memorization of the anecdotal materials. This approach not only facilitates the reconstruction of early frameworks of information management and knowledge acquisition, but also places the “Chu shuo” chapters in a comparative context. It also proffers new answers to several long-standing philological debates, such as the meaning and function of the label yi yue 一曰. In its conclusion, this study draws attention to potential continuities between the pre-imperial and imperial periods’ textual and bibliographical practices. (shrink)

This article presents counter evidence against Smolensky's theory that human intuitive/nonconscious congnitive processes can only be accurately explained in terms of subsymbolic computations carried out in artificial neural networks. We presentsymboliclearning models of two well‐studied, complicated cognitive tasks involving nonconscious acquisition of information: learning production rules and artificial finite state grammars. Our results demonstrate that intuitive learning does not imply subsymbolic computation, and that the already well‐established, perceived correlation between “conscious” and “symbolic” on the one hand, and between (...) “nonconscious” and “subsymbolic” on the other, does not exist.

This article examines how the historian deals with ‘information’ broadly conceived, especially its acquisition, retention and loss. Ammianus details a complex interplay between those who control information and those who must work with an information deficit. Just as this dialogue plays out within the text, however, so too does it with respect to the author's methodology, which dances between the poles of incomplete and complete information depending on circumstance. Ammianus thus becomes an author as hard (...) to pin down as many of his characters, by turns the omniscient narrator and the dumbfounded participant. (shrink)

This paper investigates young children's knowledge of scalar implicatures and downward entailment. In previous experimental work, we have shown that young children access the full range of truth-conditions associated with logical words in classical logic, including the disjunction operator, as well as the indefinite article. The present study extends this research in three ways, taking disjunction as a case study. Experiment 1 draws upon the observation that scalar implicatures (SIs) are cancelled (or reversed) in downward entailing (DE) linguistic environments, e.g., (...) in the scope of negation (Chierchia, 2000). Experiment 2 was designed to determine if scalar implicatures are used by children, like adults, to influence the interpretation of disjunction in non-DE contexts, yielding an implicature of exclusivity for disjunction. Whereas adult controls always rejected assertions of the form A or B in positive (non-DE) contexts in which assertions of the form A and B were also true, many children accepted assertions with disjunction in such contexts. To provide an interpretation to the findings from Experiment 2, a new experimental technique was devised and used in Experiment 3. The new technique presents pairs of assertions to children, who are asked to judge which assertion is a ‘better’ description of the context. The findings from Experiment 3 demonstrated children's awareness that A and B is more informative than A or B in positive contexts, where both statements are true. Taken together, the findings of Experiments 2 and 3 are compatible with the view that some children lack the computational resources to apply scalar implicatures when a single assertion is presented alone (see Reinhart, 1999).

The picture of information acquisition as the elimination of possibilities has proven fruitful in many domains, serving as a foundation for formal models in philosophy, linguistics, computer science, and economics. While the picture appears simple, its formalization in dynamic epistemic logic reveals subtleties: given a valid principle of information dynamics in the language of dynamic epistemic logic, substituting complex epistemic sentences for its atomic sentences may result in an invalid principle. In this article, we explore such failures (...) of uniform substitution. First, we give epistemic examples inspired by Moore, Fitch, and Williamson. Second, we answer affirmatively a question posed by van Benthem: can we effectively decide when every substitution instance of a given dynamic epistemic principle is valid? In technical terms, we prove the decidability of this schematic validity problem for public announcement logic (PAL and PAL-RC) over models for finitely many fully introspective agents, as well as models for infinitely many arbitrary agents. The proof of this result illuminates the reasons for the failure of uniform substitution. (shrink)

Referring to entities is one of the key functions of language; learning to understand and use the relevant referential expressions is one of children’s major linguistic achievements. The 13 chapters of this volume bring together a wealth of information on the acquisition of referential processes in infants, pre-schoolers and school-age children drawing on data from more than 25 languages ranging from Italian to Inuktitut, and from Norwegian to Turkish. This book presents the state-of-the-art of corpus and experimental research (...) on the acquisition of reference. The breadth of aspects of referential acquisition will make the volume appealing to a wide audience of researchers, including linguists and psycholinguists working on phonological, morpho-syntactic, and discourse-pragmatic aspects of language development. The cross-linguistic perspective adopted by several of the contributors will be of particular interest to researchers investigating the relevance of typological differences. The state-of-the-art approach makes the research accessible to specialist and non-specialist researchers alike, and will provide an invaluable resource for graduate-level courses. (shrink)

The distributional principle according to which morphemes that occur in identical contexts belong, in some sense, to the same category [1] has been advanced as a means for extracting syntactic structures from corpus data. We extend this principle by applying it recursively, and by using mutual information for estimating category coherence. The resulting model learns, in an unsupervised fashion, highly structured, distributed representations of syntactic knowledge from corpora. It also exhibits promising behavior in tasks usually thought to require representations (...) anchored in a grammar, such as systematicity. (shrink)
