The current paradigm in medicine generally distinguishes between genetic and environmental causes of disease. Although the word paradigm has become a commonplace, the theories of Thomas Kuhn have not received much attention in the journals of medicine. Kuhn's structuralist method differs radically from the daily activities of the scientific method itself. Using linguistic theory, this essay offers a structuralist reading of Thomas Kuhn's The Structure of Scientific Revolutions. Our purpose is to highlight the similarities between these structuralist models of science and language. In part, we focus on the logic that enables Kuhn to assert the priority of perception over interpretation in the history of science. To illustrate some of these issues, we refer to the distinction between environmental and genetic causes of disease. While the activity of scientific research results in the revision of concepts in science, the production of significant differences that shape our knowledge is in part a social and linguistic process.  相似文献

Two experiments were run in order to investigate the relationship between syllable length of number names and eye-fixation durations during silent reading of one- and two-digit numbers. In Experiment 1, subjects had to read a series of three numbers and recall them orally; in Experiment 2, subjects had to indicate manually whether the value of the middle number was between the values of the outer numbers. The effect of syllable length was controlled for possible confounding effects of number frequency and number magnitude. Findings indicated that fixation duration depended on syllable length of number names in the first task, but not in the second task. The results call into question the claim that phonological encoding is imperative in visual processing; phonological encoding was used only when the numbers had to be recalled, and not when they were coded for computational purposes.  相似文献

Internal consistency of two forms of the Geriatric Treatment Acceptability Survey (GTAS) and the Attitudes toward Behavior Analysis Scale (ABAS), a global measure of attitudes toward behavior modification, was evaluated. Alpha coefficients regarding treatment acceptability ratings for GTAS Form H were: (a) wandering 0.94; (b) hoarding 0.96; (c) disruptive behavior 0.92; (d) property destruction 0.95; and (e) aggression 0.94. Internal consistency for Form NH was: (a) wandering 0.96; (b) hoarding 0.97; (c) disruptive behavior 0.96; (d) property destruction 0.97; and (e) aggression 0.76. Internal consistency of the ABAS resulted in alpha coefficients of 0.90 (total score); 0.87 (ethics and humaneness); and 0.76 (use). These measures appear useful in assessing older adults, nursing home patients' and geriatric nursing staffs' global and specific attitudes regarding the use of behavioral treatments with older adults. Further research is needed to establish psychometric constructs assessed by the instruments and sensitivity to detecting change in attitudes based on educational or clinical interventions.  相似文献

The frequency of social initiations and satisfaction with interactions in three dyads, each consisting of 1 student with disabilities and 1 nondisabled peer, were assessed under two alternating conditions: Condition 1 assessed the interactions around a set of four trained computer games, and Condition 2 assessed interactions when students were playing a set of four untrained computer games. Training was conducted with a multiple baseline design across participants and was followed by social interaction probes using an alternating treatments design. The results indicated greater frequencies of social initiations by 5 of 6 participants, higher degrees of game satisfaction by all participants, and equal or higher degrees of peer satisfaction by 5 of 6 participants when playing trained games in comparison to untrained games.  相似文献

Proponents of double-effect reasoning — relying in part on a distinction between intention and foresight — assert that it is worse intentionally to cause harm than to cause harm with foresight but without intention. They hold, for example, that terror bombing is worse than tactical bombing in so far as terror bombing is the intentional harming of non-combatants while tactical bombing is not. In articulating the ethical relevance of the intended/foreseen distinction, advocates of double effect employ the Kantian end-not-means principle.
Jonathan Bennett has recently argued that this principle cannot ground the ethical relevance of the intended/foreseen distinction. He holds that the principle demands that one benefit others while double effect deals with acts that do not benefit others. Thus, he maintains, the intended/foreseen distinction does not have ethical import and double effect is not tenable. I argue for a reading of the end-not-means principle that grounds the ethical relevance of both the intended/foreseen distinction and double effect.  相似文献

Three longitudinal samples of children (N = 481), 8 to 16 years old, were assessed 3 times at yearly intervals on 8 water-level items. The within-child change in task performance over age is viewed as a stochastic process of the child changing or remaining in 1 of 3 latent (strategy) states: (a) bottom-parallel responders, (b) random responders, or (c) accurate responders. A random-effects binomial mixture distribution is used to model performance at each age. Change over age is gauged by a stochastic transition model. Although there was improvement in task performance over age, the more general finding is that strategy stability, not change, is most typical.  相似文献

Two main questions were addressed in the present study. First, does the existence of kinematic regularities in the extrinsic space represent a general rule? Second, can the existence of extrinsic regularities be related to specific experimental situations implying, for instance, the generation of compliant motion (i.e. a motion constrained by external contact)? To address these two questions we studied the spatio-temporal characteristics of unconstrained and compliant movements. Five major differences were observed between these two types of movement: (1) the movement latency and movement duration were significantly longer in the compliant than in the unconstrained condition; (2) whereas the hand path was curved and variable according to movement direction for the unconstrained movements, it was straight and invariant for the compliant movements; (3) whereas the movement end-point distribution was roughly circular for the unconstrained movements, it was consistently elongated and typically oriented in the movement direction for the compliant movements; (4) whereas constant errors varied as a function of target eccentricity for the unconstrained movements, they were independent of this factor for the compliant movements; (5) the instruction to move the final effector along a straight line path influenced the characteristics of the unconstrained movements but not the characteristics of the compliant movements. When considered together, the previous observations suggest that compliant and unconstrained movements involve different planning strategies. Our data support the hypothesis that unconstrained motions, unlike compliant motions, are not programmed to follow a straight line path in the extrinsic space. This observation provides a theoretical frame of reference within which some apparently contradictory results reported in the movement generation literature may be explained.  相似文献

To investigate infants’ affective expressivity and maternal attuned responsiveness to infant expressivity in relation to early language achievement, 77 dyads were visited in their homes at 9 and 13 months, and mothers were interviewed about their children’s language between 9 and 21 months. Maternal responses that were attuned to infant affect, by selectively matching either the gradient features or the valence of infants’ affective expressions, were more predictive of children’s language achievement than maternal nonmatching responses; and maternal matching responses at 9 months were more predictive of children’s language achievements than maternal responses at 13 months. Moreover, maternal matching responses at 9 months predicted second-year language achievements over and above infant affect expressivity at 9 and 13 months, and over and above maternal matching responses at 13 months. Infants’ affective expressivity per se was not predictive.  相似文献
