The purpose of the present experiments was to explore chicks' proximity seeking behaviour in relation to imprinting objects in unfamiliar settings. Experiment I showed that chicks, which were individually imprinted on a stationary imprinting object, displayed reduced proximity seeking behaviour when tested in a pen smaller than the rearing pen. This finding confirmed earlier work on the effects of changed pen size. Experiment II used continuous and intermittent noise rearing and testing conditions, in all possible combinations, and a stationary imprinting object. Increased proximity seeking was found in conditions where the auditory environment was changed from rearing to testing, a result apparently opposite to that obtained in earlier work. It is suggested that the effect of environmental change on proximity seeking may vary with the modality in which change occurs and the salience of the imprinting object. 相似文献

In recent years, there has been growing discussion amongst philosophers about “conceptual engineering”. Put roughly, conceptual engineering concerns the assessment and improvement of concepts, or of other devices we use in thought and talk (e.g., words). This often involves attempts to modify our existing concepts (or other representational devices), and/or our practices of using them. This paper explores the relation between conceptual engineering and conceptual ethics, where conceptual ethics is taken to encompass normative and evaluative questions about concepts, words, and other broadly “representational” and/or “inferential” devices we use in thought and talk. We take some of the central questions in conceptual ethics to concern which concepts we should use and what words should mean, and why. We put forward a view of conceptual engineering in terms of the following three activities: conceptual ethics, conceptual innovation, and conceptual implementation. On our view, conceptual engineering can be defined in terms of these three activities, but not in a straightforward, Boolean way. Conceptual engineering, we argue, is made up of mereologically complex activities whose parts fall into the categories associated with each of these three different activities. 相似文献
