Structuring argumentation in a social constructivist framework: A pedagogy with computer support

What we usually think of as higher order skills in argumentation can be profitably viewed as systematic structures for organizing and representing information. Standard terms like line of argument, synthesis, analysis and draft can be viewed as ways of constructing, storing, and accessing data in a social context — data structures for social communication. What makes argument difficult are the multiple structures that arguers have to construct and negotiate when reading and composing. In this paper, we describe the WARRANT project, a project designed to identify data structures of written argument and to design and implement computer tools to aid in the reading and design of argument.     

Voice reaction times with recognition for Commodore computers

Hardware and software modifications are presented that allow for collection and recognition by a Commodore computer of spoken responses. Responses are timed with millisecond accuracy and automatically analyzed and scored. Accuracy data for this device from several experiments are presented. Potential applications and suggestions for improving recognition accuracy are also discussed.     

Negative priming insame-different matching: Further evidence for a central locus of inhibition

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as “same” or “different.” Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.     

Graphic precision: Controlling stimulus displays on IBM PC-compatible computers

Tachistoscopic presentation of stimuli on IBM PC-compatible computers is limited by a number of factors, including video retrace rates, screen scrolling, and the shape and density of picture elements. A method is presented for overcoming these difficulties through the use of enhanced graphic adapters or video graphic arrays. A C-language program demonstrates (1) synchronous scroll-free displays achieved by writing alternating images to “hidden” pages of video memory, (2) alternative techniques for erasing images, and (3) use of an empirically derived aspect ratio to produce symmetrical figures.     

THE WILL ROGERS ILLUSION IN JUDGMENTS ABOUT SOCIAL GROUPS

Abstract— Subjects' judgments of the mean of 12 scores were influenced by the way in which the scores were dichotomized. The estimated mean was higher when the three highest scores formed one group (e.g., payments for women) and the nine lowest formed the other (e.g., payments for men) than when the nine highest were one group and the three lowest the other. We call this phenomenon the Will Rogers Illusion (WRI). The WRI occurred only when estimates of the subgroup means were made prior to the estimates of the mean of the whole group. When the latter mean was judged first, the WRI was reversed. These and other data indicate that the means of subgroups can influence judgments of group means, a finding that is relevant to research on social stereotypes.     

God and free speech: A quaker perspective on the Satanic Verses controversy

This paper offers a Quaker perspective on the issues raised for British society by the Satanic Verses controversy. It is argued that the Quaker rejection of coercive power is founded upon the story of Jesus Christ. The origins of Quaker attitudes to free speech are located in seventeenth‐century Puritanism, arguing that Quakers share with Western secular defenders of free speech an internalization of the blasphemy taboo which issues in intolerance of anything held sacred. Furthermore, free speech rhetoric tends to ignore the power relations which sustain free speech in particular contexts. This is a neglect which, coupled with a secularized theory of race relations that ignores religious factors, renders its protagonists incapable of addressing anti‐Islamic prejudice, a phenomenon illustrated from press coverage of the controversy. The implications of this argument for British society and Quakers in particular are then considered. It is argued that an extension of legislation covering incitement to racial hatred to religion is the most appropriate legal response, but the greatest need is educational. Quakers and other Christian groups need to develop their own theological response to avoid passively replicating the dominant view in society.     

On the disunity of the self: A systems theory of personality

The views of a variety of theorists who have proposed that the mind may be usefully conceptualized as made up of a set of subselves are reviewed, and several principles are proposed for a possible systems theory of personality.     

Research in Consultation: Toward Better Analogues and Outcome Measures

Recommendations for improving consultation research include (a) strengthening consultation analogue research by incorporating “boundary” conditions into research designs and (b) extending the outcome measures used.
