We reconsider the Nagelian theory of reduction and argue that, contrary to a widely held view, it is the right analysis of
intertheoretic reduction. The alleged difficulties of the theory either vanish upon closer inspection or turn out to be substantive
philosophical questions rather than knock-down arguments. 相似文献

In this cross-sectional study, we explored the relationship between premorbid personality and its changes over 5 years, and cognitive deterioration in patients with mild Alzheimer’s disease. The cognitive level of 54 patients was compared with that of 64 control subjects using the Mini Mental State (MMSE). Family members completed the NEO-PI-R (form R) twice, once to evaluate the participants’ current personality and again to assess personality traits as they were remembered to be 5 years earlier. Furthermore, the family filled in the Informant Questionnaire on Cognitive Decline (IQCODE), the Activities of Daily Living (ADL), and the Instrumental Activities of Daily Living (IADL) scales to assess their proxies’ cognitive level and daily living functioning. Regarding the relationship between personality characteristics and cognitive status, we observed trends for premorbid personality and significant links for personality changes in the clinical group. Thus, changes in neuroticism and conscientiousness were associated with cognitive deterioration, whereas decreased openness to experience and conscientiousness over time predicted loss of independence in daily functioning in the clinical group. Our study suggests that premorbid features can be considered as latent traits linked to the neuropathology underlying the disease process, while personality changes are probably the consequences of the pathological process. 相似文献

Studies on the productive failure (PF) approach have demonstrated that attempting to solve a problem prepares students more effectively for later instruction compared to observing failed problem-solving attempts prior to instruction. However, the examples of failure used in these studies did not display the problem-solving-and-failing process, which may have limited the preparatory effects. In this quasi-experiment, we investigated whether observing someone else engaging in problem solving can prepare students for instruction, and whether examples that show the problem-solving-and -failing process are more effective than those that only show the outcome of this process. We also explored whether the perceived model–observer similarity had an impact on the effectiveness of observing examples of failure. The results showed that observing examples effectively prepares students for learning from instruction. However, observing the model's problem-solving-and-failing process did not prepare students more effectively than merely looking at the outcome. Studying examples were more effective if model–observer similarity was high. 相似文献

Audiovisual synchrony and temporal order judgments: effects of experimental method and stimulus type
When an audio-visual event is perceived in the natural environment, a physical delay will always occur between the arrival of the leading visual component and that of the trailing auditory component. This natural timing relationship suggests that the point of subjective simultaneity (PSS) should occur at an auditory delay greater than or equal to 0 msec. A review of the literature suggests that PSS estimates derived from a temporal order judgment (TOJ) task differ from those derived from a synchrony judgment (SJ) task, with (unnatural) auditory-leading PSS values reported mainly for the TOJ task. We report data from two stimulus types that differed in terms of complexity--namely, (1) a flash and a click and (2) a bouncing ball and an impact sound. The same participants judged the temporal order and synchrony of both stimulus types, using three experimental methods: (1) a TOJ task with two response categories ("audio first" or "video first"), (2) an SJ task with two response categories ("synchronous" or "asynchronous"; SJ2), and (3) an SJ task with three response categories ("audio first," "synchronous," or "video first"; SJ3). Both stimulus types produced correlated PSS estimates with the SJ tasks, but the estimates from the TOJ procedure were uncorrelated with those obtained from the SJ tasks. These results suggest that the SJ task should be preferred over the TOJ task when the primary interest is i n perceived audio-visualsynchrony. 相似文献

The spatial representation of ordinal sequences (numbers, time, tones) seems to be a fundamental cognitive property. While an automatic association between horizontal space and pitch height (left-low pitch, right-high pitch) is constantly reported in musicians, the evidence for such an association in non-musicians is mixed. In this study, 20 non-musicians performed a line bisection task while listening to irrelevant high- and low-pitched tones and white noise (control condition). While pitch height had no influence on the final bisection point, participants’ movement trajectories showed systematic biases: When approaching the line and touching the line for the first time (initial bisection point), the mouse cursor was directed more rightward for high-pitched tones compared to low-pitched tones and noise. These results show that non-musicians also have a subtle but nevertheless automatic association between pitch height and the horizontal space. This suggests that spatial–musical associations do not necessarily depend on constant sensorimotor experiences (as it is the case for musicians) but rather reflect the seemingly inescapable tendency to represent ordinal information on a horizontal line. 相似文献

The authors investigate primary, hysterical, narcissistic identification, and introjection as conceptualised by Freud, Melanie Klein’s projective identification, and Anna Freud’s identification with the aggressor and altruistic surrender. It is pointed out that hysterical identification, narcissistic identification, and introjection are unconscious processes leading into a state of primary identification, and that they can be distinguished on a clinical level as regards the emotional meaning the object has for the subject. In hysterical identification the aspects of an object with which one identifies and all its other aspects retain their emotional meaning, in narcissistic identification these other aspects also keep their emotional meaning, but in this case the aspects with which one identifies lose their emotional meaning, and in introjection all aspects of an object lose their emotional meaning. Furthermore, it is shown that hysterical or narcissistic identifications are the mechanisms underlying the identification with the aggressor, and that—along with projections—hysterical re-identification also plays a decisive role in projective identification and altruistic surrender, whereby in these latter processes the object identifies himself unconsciously with the contents projected onto him in a hysterical or narcissistic manner. 相似文献

Bayesian Coherence Theory of Justification or, for short, Bayesian Coherentism, is characterized by two theses, viz. (i) that our degree of confidence in the content of a set of propositions is positively
affected by the coherence of the set, and (ii) that coherence can be characterized in probabilistic terms. There has been
a longstanding question of how to construct a measure of coherence. We will show that Bayesian Coherentism cannot rest on
a single measure of coherence, but requires a vector whose components exhaustively characterize the coherence properties of
the set. Our degree of confidence in the content of the information set is a function of the reliability of the sources and
the components of the coherence vector. The components of this coherence vector are weakly but not strongly separable, which
blocks the construction of a single coherence measure. 相似文献
