Philosophers of mathematics commonly distinguish between explanatory and non-explanatory proofs. An important subclass of mathematical proofs are proofs by induction. Are they explanatory? This paper addresses the question, based on general principles about explanation. First, a recent argument for a negative answer is discussed and rebutted. Second, a case is made for a qualified positive take on the issue. 相似文献

Although individuals with depression have been found to experience a higher rate of stress in their lives, it remains unclear to what extent other personal characteristics may contribute to stress generation. The current study extended past research by examining the effects of two theoretically and empirically supported cognitive vulnerabilities to depression (negative cognitive style and rumination) as predictors of dependent interpersonal and achievement events, independent events, and relational peer victimization. In a diverse sample of 301 early adolescents (56 % female; Mage?=?12.82 years), we found that negative cognitive style prospectively predicted the experience of dependent interpersonal stress and relational victimization, and that rumination did not predict stress in any of the domains. Furthermore, the occurrence of intervening stress mediated the associations between negative cognitive style and subsequent depressive symptoms. Additionally, whereas negative cognitive style predicted relational victimization among both boys and girls, girls were particularly vulnerable to developing depressive symptoms following the occurrence of relational victimization. Thus, a negative cognitive style may contribute to the occurrence of stressful events, which in turn increases depressive symptoms. Girls may be particularly reactive to relational victimization, representing one pathway through which sex differences in depression may emerge. 相似文献

Several researchers have suggested that the nature of the covariation between internalizing and externalizing disorders may be understood better by examining the associations between temperament or personality and these disorders. The present study examined neuroticism as a potential common feature underlying both internalizing and externalizing disorders and novelty seeking as a potential broad-band specific feature influencing externalizing disorders alone. Participants were 12- to 18-year-old twin pairs (635 monozygotic twin pairs and 691 dizygotic twin pairs; 48 % male and 52 % female) recruited from the Colorado Center for Antisocial Drug Dependence. Genetic and nonshared environmental influences shared in common with neuroticism influenced the covariation among distinct internalizing disorders, the covariation among distinct externalizing disorders, and the covariation between internalizing and externalizing disorders. Genetic influences shared in common with novelty seeking influenced the covariation among externalizing disorders and the covariation between major depressive disorder and externalizing disorders, but not the covariation among internalizing disorders or between anxiety disorders and externalizing disorders. Also, after accounting for genetic and environmental influences shared in common with neuroticism and novelty seeking, there were no significant common genetic or environmental influences among the disorders examined, suggesting that the covariance among the disorders is sufficiently explained by neuroticism and novelty seeking. We conclude that neuroticism is a heritable common feature of both internalizing disorders and externalizing disorders, and that novelty seeking is a heritable broad-band specific factor that distinguishes anxiety disorders from externalizing disorders. 相似文献

Some people demand an unachievable level of self-perfection, and experience extremely harsh self-criticism when they inevitably fall short of this impossibly high standard. As a result of early trauma or neglect, patients who have internalized part-objects that are particularly responsive to aggression also appear to lack supportive introjects which could normally serve to counterbalance innate aggressivity. The resultant superego malformations are overly harsh and charged with self-destructive intent. Self-attack may range from guilt-ridden self-loathing to physical assault on the body. Suicide is viewed as restorative and survivable. Treatment interventions include superego analysis as a way to identify internalized self-attack, disentangle organized self-destructive elements and support counter-balancing forces for affect tolerance. 相似文献

Although attitudes toward peace and war are usually treated as two opposite poles of one dimension, in this article we argue that they may represent two distinct dimensions. To investigate this idea, we developed and tested a new balanced measure, the Attitudes Toward Peace and War (APW) Scale, in three studies (N = 4,742) in the United States and Denmark. Exploratory and confirmatory factor analyses showed that attitudes toward peace and war formed two distinct, though negatively related, factors. Structural equation modeling showed that antecedents of attitudes toward peace included egalitarian ideological beliefs, the values of international harmony and equality, and empathic concern for others, and consequences included intentions to engage in peace‐related activities. On the other hand, antecedents of attitudes toward war included authoritarian ideological beliefs, the values of national strength and order, and less personal distress, and consequences included intentions to engage in warlike activities. Results also showed that political affiliation had an impact on the relationship between peace and war attitudes, with conservatives less likely to find the attitudes incompatible. The findings support the view that attitudes toward peace and war represent two distinct dimensions. 相似文献

The interference of incongruous attribute names on attribute identification was studied with two different attributes, color and direction, and with two modes of identifying response, verbaland nonverbal. Nonverbal responses made for less interference under all conditions. Semantic proximity produced more interference with color than with direction. Interference in this sort of task may reflect characteristic ways in which incoming attribute information is processed. 相似文献

Remindings—stimulus-guided retrievals of prior events—may help us interpret ambiguous events by linking the current situation to relevant prior experiences. Evidence suggests that remindings play an important role in interpreting complex ambiguous stimuli (Ross & Bradshaw Memory & Cognition, 22, 591–605, 1994); here, we evaluate whether remindings will influence word interpretation and memory in a new paradigm. Learners studied words on distinct visual backgrounds and generated a sentence for each word. Homographs were preceded by a biasing cue on the same background three items earlier, preceded by a biasing cue on a different background three items earlier, or followed by a biasing cue on the same background three items later. When biasing cues preceded the homographs on the same backgrounds as the homographs, the meanings of the homographs in learner-generated sentences were consistent with the biasing cues more often than in the other two conditions. These results show that remindings can influence word interpretation. In addition, later memory for the homographs and cues was greater when the meaning of the homograph in the sentence was consistent with the earlier biasing cue, suggesting that remindings enhanced mnemonic performance. Remindings play an important role in how we interpret ambiguous stimuli and enhance memory for the involved material. 相似文献

Forgetting over the short term has challenged researchers for more than a century, largely because of the difficulty of controlling what goes on within the memory retention interval. But the “recent-negative-probe” procedure offers a valuable paradigm, by examining the influences of (presumably) unattended memoranda from prior trials. Here we used a recent-probe task to investigate forgetting for visual nonverbal short-term memory. The target stimuli (two visually presented abstract shapes) on a trial were followed after a retention interval by a probe, and participants indicated whether the probe matched one of the target items. Proactive interference, and hence memory for old trial probes, was observed, whereby participants were slowed in rejecting a nonmatching probe on the current trial that nevertheless matched a target item on the previous trial (a recent-negative probe). The attraction of the paradigm is that, by uncovering proactive influences of past-trial probe stimuli, it can be argued that active maintenance in memory of those probes is unlikely. In two experiments, we recorded such proactive interference of prior-trial items over a range of interstimulus (ISI) and intertrial (ITI) intervals (between 1 and 6 s, respectively). Consistent with a proposed two-process memory conception (the active–passive memory model, or APM), actively maintained memories on current trials decayed, but passively “maintained,” or unattended, visual memories of stimuli on past trials did not. 相似文献
