Seven trends regarding the categories that tend to be impaired/preserved in category-specific semantic deficits were identified. The authors hypothesized that these trends arise despite the multiple sources of variation in patient testing because numerous factors that structure semantic memory probabilistically converge to make some categories of knowledge more susceptible to damage than others. Analysis of semantic feature norms and corpus data for 541 concepts revealed that differences in the distribution of knowledge types across categories are sufficient to explain 6 of the trends and are necessary to explain loss of knowledge about nonliving things. Feature informativeness, concept confusability, visual complexity, familiarity, and name frequency contributed to this patterning and provide insight into why knowledge about living things is most often impaired. 相似文献

What is one who takes normativity seriously to do if normativity can neither be discovered lurking out there in the world independently of us nor can it be sufficiently grasped from a merely explanatory perspective? One option is to accept that the normative challenge cannot be met and to retreat to some form of moral skepticism. Another possibility has recently been proposed by Christine Korsgaard in The Sources of Normativity where she aims to develop an account of normativity which is grounded in autonomy. Furthermore, she argues that on her account reasons are "essentially public" and that this captures how it is that we can obligate one another. In this paper I argue that there is a serious tension between her account of normativity and the publicity of reasons-namely, that if reasons are essentially public, then it is not possible for individuals to legislate laws for themselves. However, I then argue that if we revise her conception of normativity such that it is understood to involve collective rather than individual legislation that it may then be possible to account for interpersonal reasons. 相似文献

Ken Rigby 《Journal of Family Therapy》1994,16(2):173-187
The paper examines the relationship between family functioning and the involvement of adolescent schoolchildren in bully/victim problems at school. Australian high school students between the ages of 13 and 16 years completed a Family Functioning in Adolescence Questionnaire (FFAQ) as a measure of the psychosocial well-being of their families. Students were also categorized on the basis of self-reports as bullies (9%), victims (11%), bully/victims (2%) and others (78%). The families of adolescent bullies were found to be functioning less well than others on the FFAQ, as also were the families of female but not male victims. Results for sub-groups of schoolchildren are examined with respect to specific dimensions of family functioning, and the implications of differences for family therapy are discussed. 相似文献

Vagueness as a Modality 总被引:1,自引:0,他引:1
Ken Akiba 《The Philosophical quarterly》2000,50(200):359-370
I present a modal conception of vagueness and vague objects, according to which a vague object is a transworld object which coincides with one precise object in one world and with another precise object in another world. Such worlds are called precisifications; they are modal, worldly counterparts of the precisifications postulated in supervaluationism. I criticize Evans' argument against vague objects, admitting the validity of the argument, but rejecting its basic assumption that if there are vague objects, certain identity statements must be indefinite in truth value. I distinguish identity from coincidence, and claim that if there are vague objects, some statements of coincidence will be indefinite in truth-value, not statements of identity. To establish this point, I compare vagueness with temporal modality. 相似文献

The literature suggests that in-class oral participation is associated with various positive outcomes that directly contribute to academic success. The goal of the current study was to investigate the role played by psychological barriers to oral participation, focusing on commitment and self-affirmation as methods to bypass barriers to participation. The results of the semester-long experiment (N = 157) demonstrate that committed individuals who had an opportunity to self-affirm outperformed both committed students and affirmed students, as well as members of the control group. Interestingly, the interplay between self-affirmation and commitment increased oral participation, irrespective of whether students had high or low self-esteem and high or low self-efficacy. The current results offer some room for cautious optimism, as they highlight the importance of self-affirmation and commitment as a route to academic success. 相似文献

To assess the role of priming in conjunctive visual search tasks, we systematically varied the consistency of the target and distractor identity between different conditions. Search was fastest in the standard conjunctive search paradigm where identities remained constant. Search was slowest when potential target identity varied predictably for each successive trial (the 'switch' condition). The role of priming was also demonstrated on a trial-by-trial basis in a 'streak' condition where target and distractor identity was unpredictable yet was consistent within streaks. When the target to be found was the same for a few trials in a row, search performance became similar to that when the potential target was the same on all trials. A similar pattern was found for the target absent trials, suggesting that priming is based on the whole search array rather than just the target in each case. Further analysis indicated that the effects of priming are sufficiently strong to account for the advantage seen for the conjunctive search task. We conclude that the role of priming in visual search is underestimated in current theories of visual search and that differences in search times often attributed to top-down guidance may instead reflect the benefits of priming. 相似文献

Self-control means choosing a large delayed reward over a small immediate reward; impulsiveness is its opposite. The metabolic hypothesis states that the amount of self-control across species correlates negatively with metabolic rate (Tobin & Logue, 1994). Foraging honeybees have high metabolic rates; the metabolic hypothesis would predict little self-control in bees. But foraging bees work for the longterm good of their hive, conditions that seem to require self-control. In three experiments, we gave bees the choice between (1) a sweeter delayed reward and a less sweet immediate reward and (2) a large delayed reward and a small immediate reward. Bees showed much self-control, inconsistent with the metabolic hypothesis. 相似文献

Bayesians standardly identify irrelevance with probabilistic irrelevance. However, there are cases where e is probabilistically irrelevant to h but intuitively e is relevant to h. For instance, ‘Die A came up 1 and die B came up 1, 3, 5 or 6’ is probabilistically irrelevant to ‘Die A came up odd and
die B came up even’, yet, intuitively, it is not, irrelevant to that claim, in the sense that ‘Sydney has a harbour Bridge’
is irrelevant to it. In the context of decision making this notion of irrelevance combined with such rules as ‘Do not expend
resources on irrelevant evidence’ leads to bad results. A stronger notion of irrelevance fitting our intuitions and the contexts
of decision making is proposed: e is irrelevant to h if and only if every part of e is probabilistically irrelevant to every part of h. However, we need to take care in determining what counts as part of a statement. 相似文献
