We present a computational evaluation of three hypotheses about sources of deficit in sentence comprehension in aphasia: slowed processing, intermittent deficiency, and resource reduction. The ACT-R based Lewis and Vasishth model is used to implement these three proposals. Slowed processing is implemented as slowed execution time of parse steps; intermittent deficiency as increased random noise in activation of elements in memory; and resource reduction as reduced spreading activation. As data, we considered subject vs. object relative sentences, presented in a self-paced (...) listening modality to 56 individuals with aphasia and 46 matched controls. The participants heard the sentences and carried out a picture verification task to decide on an interpretation of the sentence. These response accuracies are used to identify the best parameters that correspond to the three hypotheses mentioned above. We show that controls have more tightly clustered parameter values than IWA; specifically, compared to controls, among IWA there are more individuals with slow parsing times, high noise, and low spreading activation. We find that individual IWA show differential amounts of deficit along the three dimensions of slowed processing, intermittent deficiency, and resource reduction, overall, there is evidence for all three sources of deficit playing a role, and IWA have a more variable range of parameter values than controls. An important implication is that it may be meaningless to talk about sources of deficit with respect to an abstract verage IWA; the focus should be on the individual's differential degrees of deficit along different dimensions, and on understanding the causes of variability in deficit between participants.

The major stakeholder classes in education have three distinct ways by which they judge the quality of knowledge claims. At times this can cause considerable distraction or mis-communication among stakeholders.

How important is the ability to freely control eye movements for reading comprehension? And how does the parser make use of this freedom? We investigated these questions using coregistration of eye movements and event‐related brain potentials (ERPs) while participants read either freely or in a computer‐controlled word‐by‐word format (also known as RSVP). Word‐by‐word presentation and natural reading both elicited qualitatively similar ERP effects in response to syntactic and semantic violations (N400 and P600 effects). Comprehension was better in free reading but (...) only in trials in which the eyes regressed to previous material upon encountering the anomaly. A more fine‐grained ERP analysis revealed that these regressions were strongly associated with the well‐known P600 effect. In trials without regressions, we instead found sustained centro‐parietal negativities starting at around 320 ms post‐onset; however, these negativities were only found when the violation occurred in sentence‐final position. Taken together, these results suggest that the sentence processing system engages in strategic choices: In response to words that don't match built‐up expectations, it can either explore alternative interpretations (reflected by regressions, P600 effects, and good comprehension) or pursue a “good‐enough” processing strategy that tolerates a deficient interpretation (reflected by progressive saccades, sustained negativities, and relatively poor comprehension).

Conventionality and aptness are two dimensions of metaphorical sentences thought to play an important role in determining how quick and easy it is to process a metaphor. Conventionality reflects the familiarity of a metaphor whereas aptness reflects the degree to which a metaphor vehicle captures important features of a metaphor topic. In recent years it has become clear that operationalizing these two constructs is not as simple as asking naïve raters for subjective judgments. It has been found that ratings of (...) aptness and conventionality are highly correlated, which has led some researchers to pursue alternative methods for measuring the constructs. Here, in four experiments, we explore the underlying reasons for the high correlation in ratings of aptness and conventionality, and question the construct validity of various methods for measuring the two dimensions. We find that manipulating the processing fluency of a metaphorical sentence by means of familiarization to similar senses of the metaphor (“in vivo conventionalization”) influences ratings of the sentence's aptness. This misattribution may help explain why subjective ratings of aptness and conventionality are highly correlated. In addition, we find other reasons to question the construct validity of conventionality and aptness measures: for instance, we find that conventionality is context dependent and thus not attributable to a metaphor vehicle alone, and we find that ratings of aptness take more into account than they should.

In Explaining Evil four prominent philosophers, two theists and two non-theists, present their arguments for why evil exists. Taking a "position and response" format, in which one philosopher offers an account of evil and three others respond, this book guides readers through the advantages and limitations of various philosophical positions on evil, making it ideal for classroom use as well as individual study. -/- Divided into four chapters, Explaining Evil covers Theistic Libertarianism (Richard Brian Davis), Theistic Compatibilism (Paul Helm), (...) Atheistic Moral Realism (Erik Wielenberg) and Atheistic Moral Non-realism (Michael Ruse). It features topics including free will, theism, atheism, goodness, Calvinism, evolutionary ethics, and pain, and demonstrates some of the dominant models of thinking within contemporary philosophy of religion and ethics.

What would it be like to have never learned English, but instead only to know Hopi, Mandarin Chinese, or American Sign Language? Would that change the way you think? Imagine entirely losing your language, as the result of stroke or trauma. You are aphasic, unable to speak or listen, read or write. What would your thoughts now be like? As the most extreme case, imagine having been raised without any language at all, as a wild child. What—if anything—would it be (...) like to be such a person? Could you be smart; could you reminisce about the past, plan the future? (shrink)

This paper considers a problem that arises for free will defenses when considering the nature of God's own will. If God is perfectly good and performs praiseworthy actions, but is unable to do evil, then why must humans have the ability to do evil in order to perform such actions? This problem has been addressed by Theodore Guleserian, but at the expense of denying God's essential goodness. I examine and critique his argument and provide a solution to the initial problem (...) that does not require abandoning God's essential goodness. (shrink)

An investigation is presented in which a computer simulation model (DIAGNOSER) is used to develop and test predictions for behavior of subjects in a task of medical diagnosis. The first experiment employed a process‐tracing methodology in order to compare hypothesis generation and evaluation behavior of DIAGNOSER with individuals at different levels of expertise (students, trainees, experts). A second experiment performed with only DIAGNOSER identified conditions under which errors in reasoning in the first experiment could be related to interpretation of specific (...) data items. Predictions derived from DIAGNOSER's performance were tested in a third experiment with a new sample of subjects. Data from the three experiments indicated that (1) form of diagnostic reasoning was similar for all subjects trained in medicine and for the simulation model, (2) substance of diagnostic reasoning employed by the simulation model was parable with that of the more expert subjects, and (3) errors in subjects' reasoning were attributable to deficiencies in disease knowledge and the interpretation of specific patient data cues predicted by the simulation model.

Sam Lebens has written a richly inventive and thought-provoking book that contributes greatly to philosophy of religion and to contemporary Jewish philosophy. While there is much that merits response, I will focus here on one central theme of the book: the doctrine, dubbed (Extreme) Hasidic Idealism by Lebens, that we exist only in God’s imagination — accordingly that we are nothing but divine ideas. I will also argue that the book exceeds its self-presentation as a work in the “analytic style” (...) and illustrates the need to overcome the analytic/Continental divide. (shrink)

I begin with a distinction between narrow and broad defenses to the logical problem of evil. The former is simply an attempt to show that God and evil are not logically incompat-ible whereas the latter attempts the same, but only by appealing to beliefs one takes to be true in the actual world. I then argue that while recent accounts of original sin may be consistent with a broad defense, they are also logically incoherent. After considering potential replies, I conclude (...) by proposing an account of original sin that is both logically coherent and consistent with a broad defense. (shrink)

In a previous issue of this journal Michael Veber argued that God could not answer certain prayers because doing so would be immoral. In this article I attempt to demonstrate that Veber’s argument is simply the logical problem of evil applied to a possible world. Because of this, his argument is susceptible to a Plantinga-style defense.

During the COVID-19 crisis there have been many difficult decisions governments and other decision makers had to make. E.g. do we go for a total lock down or keep schools open? How many people and which people should be tested? Although there are many good models from e.g. epidemiologists on the spread of the virus under certain conditions, these models do not directly translate into the interventions that can be taken by government. Neither can these models contribute to understand the (...) economic and/or social consequences of the interventions. However, effective and sustainable solutions need to take into account this combination of factors. In this paper, we propose an agent-based social simulation tool, ASSOCC, that supports decision makers understand possible consequences of policy interventions, but exploring the combined social, health and economic consequences of these interventions.

Peirce remarks on several occasions in the 1790s on affinities between his evolutionary metaphysics and Schelling's Idealism, behind which, he avers, lies ‘the monstrous mysticism of the East’. What are these affinities? Why are they affinities with Schelling rather than with Hegel? And what is the mysticism in question? I argue that Schelling, like Peirce but unlike Hegel, is committed to evolution, not only across species boundaries, but also across the boundary between the inorganic and the organic. Moreover, Schelling, like (...) Peirce but unlike Hegel, embeds this account of evolution in an account of the evolution of God through love. The monstrous mysticism of the East, I argue, is Lurianic kabbalah, to which Schelling is demonstrably indebted, and which is committed to an evolutionary theism on which is based, if not an account of natural evolution, an account of reincarnation as a mechanism by which life-forms progress from inorganic to organic bodies as they develop their consciousness.

This article examines three moments of the post-Kantian philosophical tradition in the nineteenth and early twentieth centuries: Kantianism, Post-Kantian Idealism, and Neo-Kantianism. It elucidates the distinctive methods of a tradition that has never entirely disappeared and is now acknowledged once again as the source of contemporary insights. It outlines two problematics—naturalist scepticism and historicist nihilism—threatening the possibility of metaphysics. The first concerns sceptical worries about reason, emerging from attempts to extend the methods of natural science to the study of human (...) beings. Kant’s project of a critical and transcendental analysis of reason, with its distinctive methods, should be considered a response. The second arises from the development of new methods of historical inquiry, seeming to undermine the very possibility of individual agency. Also considered are Kant’s successors’ revisions of the critical and transcendental analysis of reason, undertaken to overcome challenges confronting the original versions of Kant’s methods. (shrink)
