We adopt here a functional approach to the classical comparison between language and biology. We first parallel events which
have a functional signification in each domain, by matching the utterance of a sentence with the release of a protein. The
meaning of a protein is then defined by analogy as “the constant contribution of the biochemical material composing the protein
to the effects produced by any release of the protein”. The proteome of an organism corresponds to an I-language (the idiolect
of an individual), and the proteome of a species is equivalent to an E-language (a language in the common sense). Proteins
and sentences are both characterized by a complex hierarchical structure, but the language property of ‘double articulation’
has no equivalent in the biological domain in this analogy, contrary to previous proposals centered on the genetic code. Besides,
the same intimate relation between structure and meaning holds in both cases (syntactic structure for sentences and three-dimensional
conformation for proteins). An important disanalogy comes from the combinatorial power of language which is not shared by
the proteome as a whole, but it must be noted that the immune system possesses interesting properties in this respect. Regarding
evolutionary aspects, the analogy still works to a certain extent. Languages and proteomes can be both considered as belonging
to a general class of systems, that we call “productive self-reproductive systems”, characterized by the presence of two dynamics:
a fast dynamics in an external domain where functional events occur (productive aspect), and a slow dynamics responsible for
the evolution of the system itself, driven by the feed-back of events related to the reproduction process. 相似文献

In brainstorming research, quantity is assumed to breed quality. However, little is known about the cognitive mechanisms underlying this relationship. A parsimonious explanation assumes a random process, in which every idea has an equal chance of being a high-quality (original and feasible) idea. In contrast, a ‘deep exploration’ approach suggests that the originality (but not the feasibility) of generated ideas is dependent on the degree to which people engage in deep exploration of their knowledge. We conducted two experiments to test the latter hypothesis. Prior to a brainstorming task, participants were primed with subcategories of the brainstorming topic. Priming caused a higher relative productivity and average originality within the primed subcategory, but did not affect global productivity and originality across categories. This effect was replicated in dyadic interactions. These results support the deep exploration hypothesis, and suggest that the relationship between quantity and quality is more complex than has previously been assumed. 相似文献

How Can People Be Induced to Willingly Change Their Behavior? The Path from Persuasive Communication to Binding Communication 总被引:1,自引:0,他引:1
Robert-Vincent Joule Fabien Girandola Françoise Bernard 《Social and Personality Psychology Compass》2007,1(1):493-505
How can people be induced to willingly change their behavior? The present article has three main objectives. Its first purpose is to review some of the procedures pertaining to the ‘free will’ compliance paradigm. These procedures increase the likelihood that others will freely comply to one's requests (low‐ball, teasing, foot‐in‐the door, touch, and ‘you are free to’ procedures). The second objective is to introduce a theory stemming from social psychology, namely, the theory of commitment. Finally, we wish to describe the binding communication approach that can be situated at the intersection of research conducted in both the fields of communication, more specifically in the domain of persuasive communication, and the fields of commitment and free will compliance. A project carried out to encourage school children to behave in a more environmentally friendly way will be described to illustrate the approach. 相似文献

This study investigates the role of the temporal lobes in levels-of-processing tasks (phonetic and semantic encoding) according to the nature of recall tasks (free and cued recall). These tasks were administered to 48 patients with unilateral temporal epilepsy (right "RTLE"=24; left "LTLE"=24) and a normal group (n=24). The results indicated that LTLE patients were impaired for semantic processing (free and cued recall) and for phonetic processing (free and cued recall), while for RTLE patients deficits appeared in free recall with semantic processing. It is suggested that the left temporal lobe is involved in all aspects of verbal memory, and that the right temporal lobe is specialized in semantic processing. Moreover, our data seem to indicate that RTLE patients present a retrieval processing impairment (semantic condition), whereas the LTLE group is characterized by encoding difficulties in the phonetic and semantic condition. 相似文献

This article presents MANULEX, a Web-accessible database that provides grade-level word frequency lists of nonlemmatized and
lemmatized words (48,886 and 23,812 entries, respectively) computed from the 1.9 million words taken from 54 French elementary
school readers. Word frequencies are provided for four levels: first grade (G1), second grade (G2), third to fifth grades
(G3-5), and all grades (G1-5). The frequencies were computed following the methods describedby Carroll, Davies, and Richman
(1971) and Zeno, Ivenz, Millard, and Duwuri (1995), with four statistics at each level (F, overall word frequency;D, index of dispersion across the selectedreaders;U, estimated frequencyper million words; andSFI, standard frequency index). The database also provides the number of letters in the word and syntactic category information.
MANULEX is intended to be a useful tool for studying language development through the selection of stimuli based on precise
frequency norms. Researchers in artificial intelligence can also use it as a source of information on natural language processing
to simulate written language acquisition in children. Finally, it may serve an educational purpose by providing basic vocabulary
lists. 相似文献

Alzheimer's disease disrupts arithmetic fact retrieval processes but not arithmetic strategy selection 总被引:1,自引:0,他引:1
Three groups of healthy younger adults, healthy older adults, and probable AD patients, performed an addition/number comparison task. They compared 128 couples of additions and numbers (e.g., 4 + 9 15) and had to identify the largest item for each problem by pressing one of two buttons located under each item. Manipulations of problem characteristics (i.e., problem difficulty and splits between correct sums and proposed numbers) enabled us to examine strategy selection and specific arithmetic fact retrieval processes. Results showed that arithmetic facts retrieval processes, which were spared with aging, were impaired in AD patients. However, AD patients were able to switch between strategies across trials according to problem characteristics as well as healthy older adults, and less systematically than healthy younger adults. We discuss implications of these findings for further understanding AD-related differences in arithmetic in particular, and problem solving in general. 相似文献
