Theory change is a central concern in contemporary epistemology and philosophy of science. In this paper, we investigate the
relationships between two ongoing research programs providing formal treatments of theory change: the (post-Popperian) approach
to verisimilitude and the AGM theory of belief change. We show that appropriately construed accounts emerging from those two
lines of epistemological research do yield convergences relative to a specified kind of theories, here labeled “conjunctive”.
In this domain, a set of plausible conditions are identified which demonstrably capture the verisimilitudinarian effectiveness
of AGM belief change, i.e., its effectiveness in tracking truth approximation. We conclude by indicating some further developments
and open issues arising from our results. 相似文献
The evolution of symptoms, emotional state and daily routines in patients with breast cancer and lung cancer during treatment with intravenous chemotherapy (CT) is described and the influence of anxiety and depression on these variables is analyzed. 66 patients, 29 with breast cancer and 37 with lung cancer, were evaluated before starting treatment, and after completing the first, second and last cycle of CT using the Hospital Anxiety and Depression Scale (HADS), rating scales and interview. Less than 30% of the patients showed clinical anxiety or depression according to the HADS. Throughout the treatment, tiredness, fatigue and nausea increased significantly and work and leisure activity decreased. Concern about the future of relatives and insomnia increased significantly over time in patients with breast cancer whereas they decreased in patients with lung cancer. By introducing the HADS scores as covariates, it was found that most differences are due to the time factor and the type of cancer. During treatment with CT, emotional disturbances do not seem to have significant impact on the symptoms and changes in daily life reported by cancer patients. 相似文献
Rankings of scientific productivity are increasingly relevant both from an individual and a collective perspective. Therefore, making sure they are based on reliable and exhaustive information is really important. This study clearly shows that available rankings change dramatically when internationally acknowledged bibliometric indices are considered. Data from the 10 Professors belonging to the 'Personality, Assessment, and Psychological Treatment' Department considered in the recent analysis by Olivas-ávila y Musi-Lechuga ( Psicothema 2010. Vol. 22, no 4, pp. 909-916) are revisited here for illustrative purposes. 相似文献
Episodic and autobiographical memory are clearly related, yet in both the adult and developmental literatures it is difficult to compare them because of differences in how the constructs are assessed, including differences in content, levels of control, and time since experience. To address these issues, we directly compared children's and adults' autobiographical and episodic memory using the same controlled paradigm. Participants engaged in a photo-taking activity in a museum (autobiographical encoding) and viewed others' photographs of the same museum exhibits (episodic encoding). At test, participants classified photos as ones they took, viewed, or novel. In the autobiographical condition older children and adults performed similarly; younger children's performance was lower than adults'. In contrast, in the episodic condition both groups of children performed more poorly than adults. The findings suggest the developmental primacy of autobiographical relative to episodic memory, and that traditional episodic tasks may underestimate older children's declarative memory abilities. 相似文献
Face processing is widely understood to be a basic, universal visual function effortlessly achieved by people from all cultures and races. The remarkable recognition performance for faces is markedly and specifically affected by picture-plane inversion: the so-called face-inversion effect (FIE), a finding often used as evidence for face-specific mechanisms. However, it has recently been shown that culture shapes the way people deploy eye movements to extract information from faces. Interestingly, the comparable lack of experience with inverted faces across cultures offers a unique opportunity to establish the extent to which such cultural perceptual biases in eye movements are robust, but also to assess whether face-specific mechanisms are universally tuned. Here we monitored the eye movements of Western Caucasian (WC) and East Asian (EA) observers while they learned and recognised WC and EA inverted faces. Both groups of observers showed a comparable impairment in recognising inverted faces of both races. WC observers deployed a scattered inverted triangular scanpath with a bias towards the mouth, whereas EA observers uniformly extended the focus of their fixations from the centre towards the eyes. Overall, our data show that cultural perceptual differences in eye movements persist during the FIE, questioning the universality of face-processing mechanisms. 相似文献
There are several studies showing that working memory and intelligence are strongly related. However, working memory tasks require simultaneous processing and storage, so the causes of their relationship with intelligence are currently a matter of discussion. The present study examined the simultaneous relationships among short-term memory (STM), working memory (WM), and general intelligence (g). Two hundred and eight participants performed six verbal, quantitative, and spatial STM tasks, six verbal, quantitative, and spatial WM tasks, and eight tests measuring fluid, crystallized, spatial, and quantitative intelligence. Especial care is taken to avoid misrepresenting the relations among the constructs being studied because of specific task variance. Structural equation modelling (SEM) results revealed that (a) WM and g are (almost) isomorphic constructs, (b) the isomorphism vanishes when the storage component of WM is partialed out, and (c) STM and WM (with its storage component partialed out) predict g. 相似文献
Robust literature on commuter stress has shown the multiple impact of daily commuting in people's lives. Framed within a rhizomatic approach to narratives, we analyzed stories of 11 working and 9 student Filipino commuters by looking at the ways they act on or reconstruct themselves to manage stress. In urban Metro Manila, our findings showed three narrative “stress entryways”: getting caught by the wave, seating privileges, and stuck in transit. Theoretical and practical implications of findings on commuter well-being (e.g., keeping emotions in, releasing tensions), technologies of the “fit” commuter, and enriching conversations in traffic psychology and urban living are discussed. 相似文献
The idea that what we perceive are tropes (abstract particulars) is anything but new. In fact, it was one of the reasons why the ontology of tropes was postulated in the first place. Still, the claim that we perceive tropes is invariably and purely based on pre-philosophical intuitions or, indirectly, either as a supporting argument for the advantages of content view when compared to the relational view of experience, or as a supporting argument in favor of the irreducible subjective character of experience. In this paper, I take the content view for granted and argue in favor of what is herein referred to as the trope-content view of experience. My defense is a case of inference to the best explanation. The trope-content view can meet all reasonable desiderata on the experience and its content without assuming gaps or making the ad hoc assumption that there are different layers of content, or so shall I argue.
In this paper I take side on externalist incompatibilism. However, I intend to radicalize the position. First, based on my criticism of Burge's anaphoric proposal, I argue that there is no reasoning‐transparency: the reasoner is blind to the reasoning he is performing. Second, assuming a global form of content‐externalism, I argue that “in the head” are only logical and formal abilities. That is what I call “bite the bullet and swallow it too.” 相似文献
