A moratorium on cyborgs: Computation,cognition, and commerce

By examining the contingent alliance that has emerged between the computational theory of mind and cyborg theory, we discern some questionable ways in which the literalization of technological metaphors and the over-extension of the “computational” have functioned, not only to influence conceptions of cognition, but also by becoming normative perspectives on how minds and bodies should be transformed, such that they can capitalize on technology’s capacity to enhance cognition and thus amend our sense of what it is to be “human”. We consider “a moratorium on cyborg discourse” as a way of focusing the conceptual and social–political problems posed by this alliance.     

The memorial consequences of multiple-choice testing

The present article addresses whether multiple-choice tests may change knowledge even as they attempt to measure it. Overall, taking a multiple-choice test boosts performance on later tests, as compared with nontested control conditions. This benefit is not limited to simple definitional questions, but holds true for SAT II questions and for items designed to tap concepts at a higher level in Bloom’s (1956) taxonomy of educational objectives. Students, however, can also learn false facts from multiple-choice tests; testing leads to persistence of some multiple-choice lures on later general knowledge tests. Such persistence appears due to faulty reasoning rather than to an increase in the familiarity of lures. Even though students may learn false facts from multiplechoice tests, the positive effects of testing outweigh this cost.     

The interpretive process in Rorschach testing

In this article, two complimentary and interwoven approaches to Rorschach interpretation are described. The first, a more structural approach, emphasizes test responses, the response process, and test rationales. Theorists with this emphasis focus primarily on the structural features of a test record?the scores and their interrelations. Interpretations drawn from the structural features of a record themselves tend to have a structural emphasis. A second approach, referred to as experiential, is more subjective and phenomenological. Based on the examiner's empathy, this approach is applied to other aspects of a Rorschach protocol such as content of responses and the testee's more spontaneous and off-handed comments. Each of these interpretive approaches must be given its due and integrated with interpretations drawn from the other.     

The testing effect and analogical problem-solving

Researchers generally agree that retrieval practice of previously learned material facilitates subsequent recall of same material, a phenomenon known as the testing effect. There is debate, however, about when such benefits transfer to related (though not identical) material. The current study examines the phenomenon of transfer in the domain of analogical problem-solving. In Experiments 1 and 2, learners were presented a source text describing a problem and solution to read which was subsequently either restudied or recalled. Following a short (Experiment 1) or long (Experiment 2) delay, learners were given a new target text and asked to solve a problem. The two texts shared a common structure such that the provided solution for the source text could be applied to solve the problem in the target text. In a combined analysis of both experiments, learners in the retrieval practice condition were more successful at solving the problem than those in the restudy condition. Experiment 3 explored the degree to which retrieval practice promotes cued versus spontaneous transfer by manipulating whether participants were provided with an explicit hint that the source and target texts were related. Results revealed no effect of retrieval practice.     

The family covenant and genetic testing

The physician-patient relationship has changed over the last several decades, requiring a systematic reevaluation of the competing demands of patients, physicians, and families. In the era of genetic testing, using a model of patient care known as the family covenant may prove effective in accounting for these demands. The family covenant articulates the roles of the physician, patient, and the family prior to genetic testing, as the participants consensually define them. The initial argument defines the boundaries of autonomy and benefit for all participating family members. The physician may then serve as a facilitator in the relationship, working with all parties in resolving potential conflicts regarding genetic information. The family covenant promotes a fuller discussion of the competing ethical claims that may come to bear after genetic test results are received.     

The testing effect as a function of explicit testing instructions and judgments of learning

During study, people monitor their learning; the output of this monitoring is captured in so-called judgments of learning (JOLs). JOLs predict later recall better if they are made after a slight delay, instead of immediately after study (the delayed JOL effect). According to the self-fulfilling prophecy (SFP) hypothesis delayed JOLs are based on covert retrieval attempts from long-term memory, and successful retrieval attempts in themselves enhance learning (the testing effect). We compared memory for 40 Swahili-Swedish paired associates after a week as a function of three different learning conditions, namely study plus (i) explicitly instructed self-testing, (ii) delayed JOLs, or (iii) less self-testing. We showed that repeated delayed JOLs lead to a memory improvement that does not differ significantly from a comparable condition where the participants are explicitly testing memory, and both the latter groups performed reliably better than a group that self-tested less. The results suggest that delayed JOLs improve long-term retention as efficiently as explicit memory testing and lend support to the SFP hypothesis.     

The future of IQ testing in education

Will IQ tests as we currently know them be used in schools in the year 2000? Will they be used as they are now or will they serve different functions? What new kinds of tests of aptitude and intelligence are likely to be developed in the next twenty years? In this article, the author attempts to answer the first two questions by considering the functions that IQ and aptitude tests now serve in schools and the trends that may modify the present pattern of test use. To answer the third question, she examines current research on intelligence and aptitude and discusses the kind of intelligence tests that might prove more useful in instructional planning.     

The development of psychological testing in China

The Chinese have been interested in assessing individual differences for thousands of years. This article traces the development of early psychological measurements in China through to the arrival of modern psychometric techniques in the early 20th century. Following the social disruption caused by the Sino‐Japanese War and the Chinese Civil War, the doctrines of the Communist Revolution and finally the Cultural Revolution forced the total abandonment of the idea of measuring individual differences. Since the end of the Cultural Revolution in the 1970s, however, the need for psychological measurement has been increasingly recognised, particularly because of needs in the fields of clinical and educational practice. As a result, there are now many university courses for training testing professionals. It is also important to have tests that are suitable to use in China. Simply to translate English‐language tests into Chinese may bias their results because of cultural differences, so tests should be revised in order to make their results equivalent, or new tests appropriate to their culture should be devised by Chinese psychologists. Psychological testing is now used in China in education, mental health, and, increasingly, in personnel selection. The expanding market economy means that effective processes for the selection of managers in business and industry are essential in China. As in many other scientific fields, the Chinese are making progress in psychometric testing and it is likely that psychological measurement of individual differences will make an important contribution to China's continued rapid economic progress in the 21st century.     

The ethics of HIV testing by physicians

This essay argues that informed consent remains desirable for both moral and practical reasons in regard to HIV testing by physicians. At the very least, respect for consent preserves patient control over treatment and affords the opportunity for education about the nature of HIV-related disorders. Nevertheless, there do appear to be circumstances under which involuntary testing may occur especially when health care workers may have become occupationally exposed to risk of HIV infection. To eliminate conflicts between health workers and their patients, however, it is desirable to work to eliminate the stigmatizing and discriminatory effects of HIV infection that can induce persons to resist testing.     

The art of model development and testing

Mathematical and computer simulation modeling are often computationally demanding procedures, so much so that even certain parts of these procedures, such as parameter estimation, exceed the capacities and speed of the best modern computer facilities. A good deal of effort has therefore been dedicated to speeding up and making more efficient programs such as those that are meant to find a global minimum of a parameter space. Our experience, however, is that such well-explored technical procedures in fact represent some of the shortest components of the total set of procedures by which models are developed. In this article we discuss what elements take up the lion’s share of development time and speculate on what lessons can be drawn concerning the role of high-performance computing in such enterprises.     

The selection of judges for preference testing

A scheme for choosing a few individuals whose preferences for given objects are most representative of those of a larger group of individuals is proposed. The method involves (a) quantifying the preferences of each individual so as to discriminate optimally among objects, (b) testing statistically whether or not a common preference continuum may be assumed for the quantified preferences, (c) constructing a linear estimator of values for the objects on this continuum, if it may be assumed, and (d) selecting as judges the least number of individuals whose quantified preferences, when used with this estimator, determine values for the objects with acceptable accuracy. A numerical example based on food preferences is presented. Preparation of this paper has been supported in part by the Quartermaster Food and Container Institute for the Armed Forces.

Automation of learning-set testing: The video-task paradigm

Researchers interested in studying discrimination learning in primates have typically utilized variations in the Wisconsin General Test Apparatus (WGTA). In the present experiment, a new testing apparatus for the study of primate learning is proposed. In the video-task paradigm, rhesus monkeys (Macaca mulatta) respond to computer-generated stimuli by manipulating a joystick. Using this apparatus, discrimination learning-set data for 2 monkeys were obtained. Performance on Trial 2 exceeded 80% within 200 discrimination learning problems. These data illustrate the utility of the video-task paradigm in comparative research. Additionally, the efficient learning and rich data that were characteristic of this study suggest several advantages of the present testing paradigm over traditional WGTA testing.     

The role of affective assessment in intelligence testing

Based on the tenets of logical learning theory and the research in its support, it was predicted that subjects (87 seventh and eighth graders) would score higher on subtests of the Wechsler Intelligence Scale for Children which they had assessed positively than on those which they had negatively assessed. This superiority on liked over disliked subtests was also predicted to be greater for Black than for White subjects and for lower class, compared with middle class, subjects. Subjects performed significantly better on their liked than on their disliked subtests, p < .01, supporting the telic human image advanced by logical learning theory. No racial or social class differences in this effect were seen.
