Studies on participation and spatial orientations of college students have examined aspects of university life, as projected through language, from a reportorial or narrative perspective, but hardly any one of these studies has been devoted exclusively to how students' participation structure, together with the activities participants orient to at the participation space, evokes shared socio-academic backgrounds and cultural constraints, a major way to gain access into the students' cognitive and pragmatic tendencies. This research, thus, addresses itself to Nigerian college students' (...) participation configuration, their participant roles, and the illocutionary goals of their encounters within the Goffmanian participation framework and discourse pragmatic parameters. For data, 100 interactions amongst students of the Faculty of Arts, University of Ibadan, Nigeria, were taped and scrutinised for participation forms and spatial descriptions. Two types of participation structure are manifest in the interactions, namely, unmarked and marked participations. The unmarked participation structure is the regular frame in which Goffman's ratification and non-ratification framework is strictly observed. The marked participation configuration, an unexpected interactional frame which bifurcates into accommodated and non-accommodated structures, takes interruptions by unaccredited participants as appropriate or inappropriate. The paper contends that participation configuration and contextual elements prescribe participant roles together with the pragmatic functions assigned to language and actions in the interactions. Thus, the illocutionary goals of participants, rooted in socio-academic matters and enabled by participation structures, spatial orientations and body language manipulations are contextually negotiated.

Nigerian Pidgin is a popular informal communicative code in Nigerian social, economic and political experience. It is sometimes spoken in formal situations in the hospital setting when participants find it pragmatically convenient. Despite its communicative significance, little research has been carried out on the use of Pidgin in conversational interactions in Nigerian hospitals, a gap this study fills by investigating how Pidgin is used in constructing emotions relating to social and medical conditions in hospitals. Seventy five interactions between doctors and (...) clients in Nigerian Pidgin were sampled; the data analysis was based centrally on relevance theory. Nigerian Pidgin evokes negative and positive emotions. Negative emotions manifest as pain and fear, while positive emotions appear as excitement and relief. Doctors and clients gain access to each other’s intentions through their shared knowledge of Pidgin, their co-construction of ailments, and their contextually based local interactional resources. They thus negotiate emotions as cue-dependent variables that are steered with the help of cognitive processes. (shrink)

La autora presenta una critica a la concepcion clasica de los sentidos asumida por la mayoria de autores naturalistas que pretenden explicar el contenido mental. Esta crítica se basa en datos neurobiologicos sobre los sentidos que apuntan a que estos no parecen describir caracteristicas objetivas del mundo, sino que actuan de forma ʼnarcisita', es decir, representan informacion en funcion de los intereses concretos del organismo.El articulo se encuentra también en: Bechtel, et al., Philosophy and the Neuroscience.

Throughout the text, fundamental questions concerning the nature of visual perception are addressed.

In Consciousness Explained, Daniel Dennett presents the Multiple Drafts Theory of consciousness, a very brief, largely empirical theory of brain function. From these premises, he draws a number of quite radical conclusions—for example, the conclusion that conscious events have no determinate time of occurrence. The problem, as many readers have pointed out, is that there is little discernible route from the empirical premises to the philosophical conclusions. In this article, I try to reconstruct Dennett's argument, providing both the philosophical views (...) behind the empirical premises, and the hidden empirical arguments behind the derivation of the philosophical conclusions.

A common view in both philosophy and the vision sciences is that, in human vision, wavelength information is primarily ‘for’ colouring: for seeing surfaces and various media as having colours. In this article we examine this assumption of ‘colour-for-colouring’. To motivate the need for an alternative theory, we begin with three major puzzles from neurophysiology, puzzles that are not explained by the standard theory. We then ask about the role of wavelength information in vision writ large. How might wavelength information (...) be used by any monochromat or dichromat and, finally, by a trichromatic primate with object vision? We suggest that there is no single ‘advantage’ to trichromaticity but a multiplicity, only one of which is the ability to see surfaces and so on as having categorical colours. Instead, the human trichromatic retina exemplifies a scheme for a general encoding of wavelength information given the constraints imposed by high spatial resolution object vision. Chromatic vision, like its partner, luminance vision, is primarily for seeing. Viewed this way, the ‘puzzles’ presented at the outset make perfect sense. 1 Reframing the Problem1.1 Introduction1.2 Three puzzles1.2.1 Why is trichromatic vision an anomaly in diurnal mammals?1.2.2 Why does the colour system occupy such a large and central part in human vision?1.2.3 Why are the blue cones so rare?1.3 Recasting the question2 The Costs and Benefits of Spectral Vision2.1 Spectral information and object vision2.2 Encoding the spectral dimension of light2.2.1 ‘General’ versus ‘specific’ encoding2.2.2 Spectral encoding and the monochromat2.2.3 Spectral encoding and the dichromat2.2.4 Spectral encoding and the human trichromat2.3 Three puzzles revisited2.3.1 Why is trichromatic vision an anomaly in diurnal mammals?2.3.2 Why does the colour system occupy such a large and central part in human vision?2.3.3 Why are the blue cones so rare3 Conclusion.

Nativists about syntactic processing have argued that linguisticprocessing, understood as the implementation of a rule-basedcomputational architecture, is spared in Williams syndrome, (WMS)subjects – and hence that it provides evidence for a geneticallyspecified language module. This argument is bolstered by treatingSpecific Language Impairments (SLI) and WMS as a developmental doubledissociation which identifies a syntax module. Neuroconstructivists haveargued that the cognitive deficits of a developmental disorder cannot beadequately distinguished using the standard gross behavioural tests ofneuropsychology and that the linguistic abilities of the (...) WMS subject canbe equally well explained by a constructivist strategy of neurallearning in the individual, with linguisitic functions implemented in anassociationist architecture. The neuroconstructivist interpretation ofWMS undermines the hypothesis of a double dissociation between SLI andWMS, leaving unresolved the question of nativism about syntax. Theapparent linguistic virtuosity of WMS subjects is an artefact ofenhanced phonological processing, a fact which is easier to demonstratevia the associationist computational model embraced byneuroconstructivism.

The book details several well-argued theories aiming to explain how the full, cohesive vista of human vision and perception is possible. The main query is broken down into several parts. The first deals with how we organize our representations of the world and whether these are processed and connected in a logical and sentential manner, or if these involve random connections across our neurons. The next part focuses on the amount of detail in the visual representations themselves and yields two (...) opposing theories: the “Literalist View”—“You See What You Think You See”—and the non-Literalist or “Functional View”—“You Don't See What You Think You See.” Also discussed is whether the intentional content of neural representations is individuated by factors external or internal to the subject. The last part of the chapter tackles how visual perception is processed and unified via the “Feature Integration Theory” or the “Recollective Theory.”. (shrink)

The chapter summarizes the discussions on perception between Churchland, Ramachandran, and Dennett. The arguments focus on a central issue—the relationship between the actual visual experience and one's internal neural representations. A detailed discourse on Dennett's Theory of Consciousness is provided, with particular focus on his explanations on the phenomenon of “filling in.” The chapter points out several weaknesses in Dennett's work, arising from his attempt to reconcile essentially divergent beliefs on philosophy as it relates to persons and science as it (...) relates to “sub-personal” processing. Three concerns are identified: first, the supposed transparency of content and a person's capacity to make mistakes in describing one's own visual experience must be reconciled; second, an explanation on the similarity of our neurological experiences with both abstract and detailed veridical content must be given; and third, computational content must be provided to support his claim of content being transparent to consciousness.

Abū Ḥanīfa (d. 150/767) discussed the main issues of the science of kalām in the first period and expressed his best views on these issues in response to the sects that he accepted as bid'ah (innovation). Later, kalām scholars tried to justify these views by using different arguments according to the changing conditions and time. Undoubtedly, one of the most important opinions that Abū Ḥanīfa expressed and passed on to the next generations from the perspective of the science of kalām (...) is those related to faith. In fact, faith is the strongest and most deep-rooted bond a believer establishes with his/her Creator. The individual shapes his world and the hereafter through this bond. On the other hand, faith is a phenomenon that does not contain doubt but carries certainty. In this respect, a person is included in the same category as a believer after she has firmly believed, and is called a believer or a Muslim, as the Qur'an puts it. Because no matter what race or color he is, he takes the same name because he believes in the same principles. Abū Ḥanīfa, who lived in a time when Muslims differed among themselves and differences of opinion increased, accepted faith as a common denominator by emphasizing the common values of Islam. Abū Ḥanīfa refers to this as "equality in faith". The issue of equality in faith, which is discussed as a result of the differentiation in matters related to the nature of faith, is shaped according to whether the action is counted as part of faith or not. Since Abū Ḥanīfa did not consider deeds a part of faith, so he advocated equality in faith. This view was adopted later by many scholars in the Māturīdī tradition. In the Hanafī-Māturīdī tradition, it can be said that the issue of equality in faith as well as issues such as confirmation and certainty in faith were shaped by the opinions of Abū Ḥanīfa. When equality in faith is accepted, one is not allowed to question the faith of another and say that his/her own faith is superior to the other because only God can know it. On the other hand, the understanding of equality in faith prevents external appearance and formalism from being decisive in one's religious life. Thus, a believer cannot accuse his brother who has deficiencies in his deeds but has faith of being infidel. When Abū Ḥanīfa's view of equality in faith is interpreted according to contemporary paradigms, his emphasis on human love, tolerance, and unity of the ummah, which has validity today, can clearly be observed. Therefore, it is seen that the reflection of a theological issue on social life is stressed in his opinion. This paper aims to study the issue of "equality in faith", one of the issues related to faith, and its reflection on social life by using the texts which are attributed to Abū Ḥanīfa. (shrink)

In this study, teleological judgments were examined as having a part of the boundless relationship of reason with the universal and unconditional, based on Kant's critical philosophy. To do this, firstly, the distinction between telos and skopos has been pointed out. The cognitive faculties of the subject as the source of finality in nature and the concepts of purposeless purposefulness were discussed. We emphasized that according to Kant's critical philosophy, the introduction of the concept of God as an internal principle (...) to natural science would be characterized as false belief. This trespassing, which causes a narrative that goes beyond the limits of our knowledge, was discussed in the context of the processes of acquiring knowledge in Kant's philosophy. In this regard, according to Kant the nature of the transition from teleological judgments to theological judgments was investigated. At the beginning of the study, the relation of telos with infinity was discussed. Afterward, the idea of purposefulness, which organizes itself in nature and eliminates blind randomness, was emphasized. The basis of the teleological principle as the inner principle of natural science was analyzed. The possibility of placing the concept of God on this very ground was discussed. It was pointed out that the characteristics of universality and necessity that Kant attributed to purposefulness were not only based on the grounds of experience. At this point, it was stated that to achieve universality, it is necessary to base on an a priori principle at the same time. The possibility that this principle could be an intention (Alm. Absicht) or a final end (Alm. Endzweck) was discussed. We focused on the request of the reason, which is applied to the conditioned and the finite, to reach the unconditional. It was stated that for Kant, the reason for the transition from teleological judgments to theological judgments was the effort to see purposeful regularity in phenomena. It was pointed out that it is a necessary step of the mind to lead this regularity to a higher telos and even to a creator, to the first being. We emphasized that concerning Kant’s critical philosophy if the concept of God was placed on the ground of natural science and the purposefulness in nature would be explained with this, and this method was used to prove the existence of God that would create an internal and non-permanent narrative. It was discussed whether this claim was an illusion. At this point, the task of the imagination performed with telos was examined. Evaluations about the concept of telos as the common ground of the subjective and the universal were included. As a result, it has been investigated how the search for the constant existing in the human mind can lead him to the existence of a God in the chain of causality. (shrink)

Over 35 years ago, Meltzoff and Moore (1977) published their famous article ‘Imitation of facial and manual gestures by human neonates’. Their central conclusion, that neonates can imitate, was and continues to be controversial. Here we focus on an often neglected aspect of this debate, namely on neonatal spontaneous behaviors themselves. We present a case study of a paradigmatic orofacial ‘gesture’, namely tongue protrusion and retraction (TP/R). Against the background of new research on mammalian aerodigestive development, we ask: How does (...) the human aerodigestive system develop and what role does TP/R play in the neonate’s emerging system of aerodigestion? We show that mammalian aerodigestion develops in two phases: (1) from the onset of isolated orofacial movements in utero to the post-natal mastery of suckling at 4 months after birth, and; (2) thereafter, from preparation to the mastery of mastication and deglutition of solid foods. Like other orofacial stereotypies, TP/R emerges in the first phase and vanishes prior to the second. Based upon recent advances in activity-driven early neural development, we suggest a sequence of three developmental events in which TP/R might participate: the acquisition of tongue control, the integration of the central pattern generator for TP/R with other aerodigestive CPGs, and the formation of connections within the cortical maps of S1 and M1. If correct, orofacial stereotypies are crucial to the maturation of aerodigestion in the neonatal period but also unlikely to co-occur with imitative behavior. (shrink)

This paper theoretically and experimentally investigates the behavior of asymmetric players in guessing games. The asymmetry is created by introducing r>1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$r>1$$\end{document} replicas of one of the players. Two-player and restricted N-player cases are examined in detail. Based on the model parameters, the equilibrium is either unique in which all players choose zero or mixed in which the weak player (r=1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$r=1$$\end{document}) imitates the strong (...) player (r>1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$r>1$$\end{document}). A series of experiments involving two and three-player repeated guessing games with unique equilibrium is conducted. We find that equilibrium behavior is observed less frequently and overall choices are farther from the equilibrium in two-player asymmetric games in contrast to symmetric games, but this is not the case in three-player games. Convergence towards equilibrium exists in all cases but asymmetry slows down the speed of convergence to the equilibrium in two, but not in three-player games. Furthermore, the strong players have a slight earning advantage over the weak players, and asymmetry increases the discrepancy in choices (defined as the squared distance of choices from the winning number) in both games.
