As a discipline of its own, the philosophy of science can be traced back to the founding of its academic journals, some of which go back to the first half of the twentieth century. While the discipline has been the object of many historical studies, notably focusing on specific schools or major figures of the field, little work has focused on the journals themselves. Here, we investigate contemporary philosophy of science by means of computational text-mining approaches: we apply topic-modeling algorithms (...) to eight major philosophy of science journals, from the 1930s up until 2017. Based on the full-text content of some 15,897 articles, we identified 25 research themes and 8 thematic clusters that show how the research agenda of the philosophy of science has changed in its content over the course of the last eight decades, up to the philosophy of science we now know. We also show how each one of the journals contributed in its own way to this thematic evolution. (shrink)

Orange heart shapes are commonly perceived as slightly reddish, which is an example of the memory color effect (MCE). Given that the MCE is a modulation of visual memories of typical colors of familiar objects, it can be considered to be a top-down effect. Whether cognitive penetration can explain MCEs has been actively debated since Macpherson argued that the belief that hearts are red alters orange perception. This paper aims to provide a credible explanation of the MCE that is consistent (...) with scientific studies. I first prove that Macpherson’s theory is not properly supported by the psychological evidence that she provides. I also show that her model contradicts a report on the neural correlate of the MCE. Next, I examine color constancy, which enables the perception of colors as constant under various illuminations, as a possible noncognitive principle for the MCE. The relationship between them, however, is not well established. Using statistical analyses of scenes around us, Purves suggests that perception is determined by the most frequent percepts. I argue that Purves’ view better explains the noncognitive aspects of visual memory and is consistent with the finding of the neural correlate of the MCE. (shrink)
