Can the West Save the East? Intrinsic Value and the Foundation of Chinese Environmental Ethics

Intrinsic value in nature is a key concept in professional environmental ethics literature in the West. Western scholars such as Holmes Rolston III and Paul Taylor argue that the philosophical foundation of environmental ethics should be based on the concept of intrinsic value in nature. Influenced by this concept, some influential Chinese environmental ethics scholars such as Yu Mouchang and Lu Feng argue that the foundation of environmental ethics in China should be based on the concept of intrinsic value in nature. This paper holds that the metaphysical, epistemological and ethical meaning of intrinsic value in nature is the legacy of Western philosophical traditions, which is in conflict with the Chinese philosophical traditions. Meanwile, the paper argues that the Daoist conception of living in harmony with nature can become the foundation for Chinese environmental ethics. The Daoist conception of living in harmony with nature is based on aesthetic appreciation of nature and people’s participation in the beauty of nature.     

Intrinsic reading motivation of Chinese preschoolers and its relationships with home literacy

The relationship between intrinsic motivation and home literacy of preschoolers was explored. One hundred and seventy-seven preschool children (3.8 to 6.6 years old) in Mainland China and one of the parents who primarily took care of each child participated in the study. Six indicators were considered as a measure of home literacy. Results showed that after controlling for parents' education level and children's age, three home literacy indicators-parental model of reading behaviour, number of books, and years of character teaching-could explain children's intrinsic reading motivation. Contrary to previous Western studies, Chinese children's freedom of book choice was not related to their intrinsic reading motivation. Results are discussed in the context of culture differences.     

Neurophysiology and neuroanatomy of smooth pursuit in humans

Smooth pursuit eye movements enable us to focus our eyes on moving objects by utilizing well-established mechanisms of visual motion processing, sensorimotor transformation and cognition. Novel smooth pursuit tasks and quantitative measurement techniques can help unravel the different smooth pursuit components and complex neural systems involved in its control. The maintenance of smooth pursuit is driven by a combination of the prediction of target velocity and visual feedback about performance quality, thus a combination of retinal and extraretinal information that has to be integrated in various networks. Different models of smooth pursuit with specific in- and output parameters have been developed for a better understanding of the underlying neurophysiological mechanisms and to make quantitative predictions that can be tested in experiments. Functional brain imaging and neurophysiological studies have defined motion sensitive visual area V5, frontal (FEF) and supplementary (SEF) eye fields as core cortical smooth pursuit regions. In addition, a dense neural network is involved in the adjustment of an optimal smooth pursuit response by integrating also extraretinal information. These networks facilitate interaction of the smooth pursuit system with multiple other visual and non-visual sensorimotor systems on the cortical and subcortical level. Future studies with fMRI advanced techniques (e.g., event-related fMRI) promise to provide an insight into how smooth pursuit eye movements are linked to specific brain activation. Applying this approach to neurological and also mental illness can reveal distinct disturbances within neural networks being present in these disorders and also the impact of medication on this circuitry.     

Lexical categories at the edge of the word

Language acquisition may be one of the most difficult tasks that children face during development. They have to segment words from fluent speech, figure out the meanings of these words, and discover the syntactic constraints for joining them together into meaningful sentences. Over the past couple of decades, computational modeling has emerged as a new paradigm for gaining insights into the mechanisms by which children may accomplish these feats. Unfortunately, many of these models assume a computational complexity and linguistic knowledge likely to be beyond the abilities of developing young children. This article shows that, using simple statistical procedures, significant correlations exist between the beginnings and endings of a word and its lexical category in English, Dutch, French, and Japanese. Therefore, phonetic information can contribute to individuating higher level structural properties of these languages. This article also presents a simple 2-layer connectionist model that, once trained with an initial small sample of words labeled for lexical category, can infer the lexical category of a large proportion of novel words using only word-edge phonological information, namely the first and last phoneme of a word. The results suggest that simple procedures combined with phonetic information perceptually available to children provide solid scaffolding for emerging lexical categories in language development.     

A nonlinear dynamic artificial neural network model of memory

Nonlinearity and dynamics in psychology are found in various domains such as neuroscience, cognitive science, human development, etc. However, the models that have been proposed are mostly of a computational nature and ignore dynamics. In those models that do include dynamic properties, only fixed points are used to store and retrieve information, leaving many principles of nonlinear dynamic systems (NDS) aside; for instance, chaos is often perceived as a nuisance. This paper considers a nonlinear dynamic artificial neural network (NDANN) that implements NDS principles while also complying with general neuroscience constraints. After a theoretical presentation, simulation results will show that the model can exhibit multi-valued, fixed-point, region-constrained attractors and aperiodic (including chaotic) behaviors. Because the capabilities of NDANN include the modeling of spatiotemporal chaotic activities, it may be an efficient tool to help bridge the gap between biological memory neural models and behavioral memory models.     

Organizational network perceptions versus reality: A small world after all?

Given the complexity of organizing and keeping track of even a small organizational network, boundedly rational people may have learned to use small world principles in perceiving friendship networks: arrange people in dense clusters, and connect the clusters with short paths. Analysis of 116 perceived friendship networks from four different organizations showed that these perceived networks exhibited greater small world properties than the actual friendship networks. Further, people perceived more friendship clustering than actually existed, and attributed more popularity and brokerage to the perceivedly-popular than to the actually-popular.     

La motivation et son ancrage utilitaire/désirable dans l’évaluation

Motivation has an important place among the personal characteristics that professional assessors take in account. A first study shows that different professionals do not choose the same criteria to assess motivation and also shows that normative factors affect their judgement. Then a series of studies focuses on the valorization of intrinsic motivation and on the anchoring in utility / desirability of this attribution of value. It appears that, compared with extrinsically motivated applicants, intrinsically motivated applicants are rather described by judges with desirable traits than with utility traits. This result is found as well with professionals and non professional respondents. So it seems that the valorization of intrinsic motivation would be more anchored in desirability than in utility, which is a difference with the norm of internality that is clearly anchored in utility.     

Chaos breeds autonomy: connectionist design between bias and baby-sitting

In connectionism and its offshoots, models acquire functionality through externally controlled learning schedules. This undermines the claim of these models to autonomy. Providing these models with intrinsic biases is not a solution, as it makes their function dependent on design assumptions. Between these two alternatives, there is room for approaches based on spontaneous self-organization. Structural reorganization in adaptation to spontaneous activity is a well-known phenomenon in neural development. It is proposed here as a way to prepare connectionist models for learning and enhance the autonomy of these models.
