范式转换与道德生活史的研究

伦理学就是一种生活观。伦理思想史的研究需要范式的转换,即由思想史转向道德生活史,研究社会变迁视野中的道德变迁,研究具体历史条件下的社会伦理关系,研究民众层面的日常道德生活。     

Biased judgments of the effects of speed change on travel time,fuel consumption and braking: Individual differences in the use of simplifying rules producing the same biases

The main purpose of this study was to identify different cognitive rules that lead to a particular judgment bias. To fulfill this purpose, a new method Spectral analysis was introduced and applied. Participants judged time saved by driving faster, fuel saved by replacing a car and braking capacity at different speeds. These problems invite the time saving bias (e.g., time saved from speed increases at higher speeds overestimated), the miles per gallon, MPG illusion (misjudgment of fuel saved by replacing a car) and the braking capacity bias (overestimation of braking capacity after speed increase). The average results replicated the biases. Spectral analysis of individual participants and problems showed that a speed difference rule explained about half of the time saving judgments and about three fourth of the MPG judgments. A difference between speeds rule described about one third of the biased braking judgments and a ratio/proportion rule about one fifth of the time saving and MPG judgments. All rules give biased judgments in all three domains. The paper ends with a discussion of hierarchies of cognitive rules, applications of the results, and how to mitigate or avoid the biases and the risks associated with the biases.     

Critical thinking in North America: A new theory of knowledge,learning, and literacy

The pace of change in the world is accelerating, yet educational institutions have not kept pace. Indeed, schools have historically been the most static of social institutions, uncritically passing down from generation to generation outmoded didactic, lecture-and-drill-based, models of instruction. Predictable results follow. Students, on the whole, do not learn how to work by, or think for, themselves. They do not learn how to gather, analyze, synthesize and assess information. They do not learn how to analyze the diverse logic of the questions and problems they face and hence how to adjust their thinking to those problems. They do not learn how to enter sympathetically into the thinking of others, nor how to deal rationally with conflicting points of view. They do not learn to become critical readers, writers, speakers and listeners. They do not learn how to use their native languages clearly, precisely, or persuasively. They do not, therefore, become literate, in the proper sense of the word. Neither do they gain much in the way of genuine knowledge since, for the most part, they could not explain the basis for what they believe. They would be hard pressed to explain, for example, which of their beliefs were based on rational assent and which on simple conformity to what they have been told. They have little sense as to how they might critically analyze their own experience, or identify national or group bias in their own thinking. They are much more apt to learn on the basis of irrational than rational modes of thought. They lack the traits of mind of a genuinely educated person: intellectual humility, courage, integrity, perseverance, and faith in reason.Happily, there is a movement in education today striving to address these problems in a global way, with strategies and materials for the modification of instruction at all levels of education. At its foundation is an emerging new theory of knowledge, learning, and literacy, one which recognizes the centrality of independent critical thinking to all substantial learning, one which recognizes that higher-order, multilogical thinking is as important to childhood as to adult learning, and as important to foundational learning in monological as in multilogical disciplines. This educational reform movement is not proposing an educational miracle cure, for its leading proponents recognize that many social and historical forces must come together before the ideals of the critical thinking movement will become a full academic reality. Schools do not exist in a social vacuum. To the extent that the broader society is uncritical so, on the whole, will be society's schools. Nevertheless, the social conditions necessary for fundamental changes in schooling are increasingly apparent. The pressure for fundamental change is growing. Whether and to what extent these needed basic changes will be delayed or side-tracked, thus requiring new periodic resurgences of this movement, with new, more elaborate articulations of its ideals, goals, and methods — only time will tell.     

The Piano, the Animus, and the Colonial Experience

Focused principally on an analysis of Ada, the mute heroine of Jane Campion's The Piano , this article shows how post–Jungian animus theory illuminates that character's mysterious personality. In particular, Ann Ulanov's thoughts about animus development are connected with Demaris Wehr's observations concerning the internalization of social oppression in an argument that shows how, notwithstanding she is a woman, Ada is a product of colonial oppression. Her mythological antecedents are also considered, and are particularly marked in that she resembles the handless maiden in Marie–Louise von Franz's analysis of that fairy tale. In this context Ada's ultimate renunciation of her husband is symbolically reinforced by the developing personality of her daughter Flora. The changes in both characters can be seen as implying not only the rebirth of Ada's psyche but also the emergence of a new psychological readiness to throw off the colonial mantle.     

Information processing in reading-disabled and nondisabled children

Reading disabled and nondisabled children (13-14 years of age) were presented lists of 10 words each at different rates (one word per 1, 2, and 4 sec), and immediately after the last word of each list they recalled the words in any order. Recall of the first few words presented from each list (the primacy effect) was lower in reading-disabled than nondisabled children, and slower presentation rates increased the primacy effect in both groups. These findings suggest that reading-disabled children are not completely failing to use elaborative encoding but are using less effective elaborative encoding than nondisabled readers. With all presentation rates, recall of the last few words (the recency effect) was comparable in both groups, suggesting that older reading-disabled children encode and recognize the stimuli and that elaborative encoding is deficient in reading-disabled in spite of adequate stimulus encoding and recognition.     

Individual differences among children in spelling and reading styles

Previous studies have found differences among children in their relative reliance on spelling-sound rules and word-specific associations in reading words. Children at one end of the continuum ("Phoenicians") rely heavily on spelling-sound rules; children at the other end ("Chinese") are more likely to use specific associations. This study found evidence for a Phoenician-Chinese continuum in spelling as well as in reading. Ability to spell nonsense word (e.g., "prunt") correlated more highly with ability to spell regular words (e.g., "grunt") than with ability to spell exception words (e.g., "front"). Children who were skilled at rules tended to overgeneralize them to exception words. In addition, a measure of rule use in spelling correlated with measures of rule use in reading.     

Classical conditioning and retention of the infant's eyelid response: effects of age and interstimulus interval

Independent groups of 10-,20-, and 30-day-old infants were subjected to a classical eyelid conditioning procedure involving either a 500- or a 1500-msec interstimulus interval (ISI). Ten days later, all received a second conditioning session. A reliable increase in conditioned responding was observed at all ages but only by infants receiving the 1500-msec ISI. Although age was not a significant factor in any conditioning measure except final performance level, which was greater for the oldest than for the youngest group, it did influence long-term retention. A reliable memory component was observed in the Session 2 performance of infants initially trained at 20 and 30 days but not at 10 days. These data demonstrate the importance of temporal parameters in the formation of conditioned associations very early in infancy and provide evidence for the long-term behavioral consequences of those associations.     

Storage and processing constraints on integrating story information in children and adults

In two experiments, this study examined the effects of integration complexity on the ability of child and adult listeners to integrate information from different sentences in a story. First and third graders and college adults were read stories containing incongruent event information and succeeding resolution information that explained the incongruency, and asked questions that probed incongruency recognition and resolution. Information storage complexity was manipulated by separating the event and resolution information and foregrounding or backgrounding the focal story characters. Processing complexity was manipulated by varying the inferential complexity of relating the resolution to the incongruent information, and the coreferential cues linking the event and resolution information. The results showed that increases in complexity adversely affected resolution integration, and more for the children than for the adults. The children's integration performance, in particular, was affected by theme discontinuity and coreferential complexity.     

Operant theory and methodology in infant vocal conditioning

The numerous mechanisms of behavior change in infant development are sometimes difficult to distinguish. Although it is agreed that elicitation and reinforcement both influence infant learning, the distinction between these two learning mechanisms was clarified in response to K. Bloom's (1984, Journal of Experimental Child Psychology, 38, 93-102) commentary. The theoretical and methodological assumptions of an functional analysis of infant behavior were made explicit in the context of the C. L. Poulson study (1983, Journal of Experimental Child Psychology, 36, 471-489). The rationale for the use of DRO schedules to control for elicitation effects of continuous reinforcement and the inadequacy of noncontingent schedules for this purpose were also discussed.
