Processing implications and presuppositions by schoolchildren and adults: A developmental cross-linguistic comparison

Findings from two experiments are reported in this study. The findings from Experiment I show that (a) processing implications on constructions with implicative verbs (Karttunen, 1970, 1971) in Greek, displaying equivalent properties to English, is an easy task for fourth-, fifth-, and sixth-graders and adults under no time restrictions, as other studies have shown; (b) processing presuppositions on implicative verbs is a difficult task even for adults, unlike Clark's (cf. particularly Clark & Clark, 1977) theory claims; (c) commissive verbs according to Austin's (1962) and Searle's (1969) analyses behave as implicative verbs, contradicting Karttunen's (1971) theory; (d) nonimplicative verbs elicit implicative meaning, unlike the predictions of Karttunen's (1970, 1971) theory. Experiment II corroborates the results from Experiment I using a non-European language (Lebanese-Arabic). The data from both experiments are discussed within the framework of Clark's theory on given-new information, pointing out its limitations to the comprehension system. Alternative explanations are suggested.     

Psychometric Properties of the Greek Inventory of the Dimensions of Emerging Adulthood (IDEA): University Student Perceptions of Developmental Features

Emerging adulthood, the transitional period from adolescence to adulthood, differs demographically and is associated with the cultural and socioeconomical environment one lives in. Its key dimensions have been explored in many countries including the USA through the IDEA instrument (Reifman et al. in J Youth Dev 2(1):1–12, 2007). Five dimensions have been identified and associated with specific items. In this paper, we aim to measure the psychometric properties of the IDEA used to measure key developmental features associated with emerging adulthood in Greece. A total of 592 University Humanity and Science students, both male (29.3 %) and female (70.7 %), aged 18–30 years were asked to complete a questionnaire battery including the IDEA and a set of demographic questions. We used structural equation modeling to identify factors underlying the IDEA. We identified three factors, which we named “Identity exploration/Feeling in-between,” “Experimentation/Possibilities/Self-focused” and “Negativity/Instability.” The first two factors appeared to be more prominent in our sample, while evidence of negativity and instability was limited among the study participants. Further analyses assessed the impact of demographic characteristics of participants on the above three factors. Age, gender and type of studies appeared to exert some influence on the perception of main features of emerging adulthood. Further research linking the criteria to the developmental features characterizing this distinct age group is required in order to unveil the intricacies of the phenomena of emerging adulthood in Greece.     

From Publics to Practitioners: Invention Power and Open Technoscience

Abstract

In technoscientific conditions what counts as knowledge creation is not primarily the individual experimental achievement that gives coherence to scientific practice and separates science from its publics; rather, it is a form of dispersed experimentation in more than human worlds: distributed invention power. Distributed invention power is organised and regulated through the pervasive securitisation of technoscience: surveillance and control of technoscientific fields as well as financialisation of its activities and research outputs. The securitisation of science reorders the traditional split between the public sphere, the private sector and the commons. The folding of each one of these spheres into the other underlies a constant, often antagonistic, oscillation between big science and open science. What is constitutive of the diverse movements that sustain open technoscience is not that they challenge technoscience as such but that they experiment with technoscience to create alternative forms of life.     

The Greek Orthodox Church and the economic crisis since 2009

In the midst of the raging socio-economic crisis that has hit Greece since 2009 the Greek Orthodox Church, under Archbishop Ieronymos II, has admirably developed its network of philanthropic work and charity meals. Open to both Greeks and immigrants, this project seems to realise Eastern Orthodox Christianity's sense of caritas and civic duty. Low key and efficient, the Orthodox Church's response to the crisis has left behind the nationalistic cries and pietistic/didactic excesses of the recent past. This article asserts, however, that, by failing to grapple with the structural causes of the crisis in a politically relevant manner and by refusing to castigate specific policies and politicians at the national and European Union level, the Greek Orthodox Church has offered a much needed palliative, but in the end has remained discursively distant from theological and political criticism of a rapacious neoliberal system and from effective engagement with Greek modernity.     

From Searle’s Chinese room to the mathematics classroom: technical and cognitive mathematics

Employing Searle’s views, I begin by arguing that students of Mathematics behave similarly to machines that manage symbols using a set of rules. I then consider two types of Mathematics, which I call Cognitive Mathematics and Technical Mathematics respectively. The former type relates to concepts and meanings, logic and sense, whilst the latter relates to algorithms, heuristics, rules and application of various techniques. I claim that an upgrade in the school teaching of Cognitive Mathematics is necessary. The aim is to change the current mentality of the stakeholders so as to compensate for the undue value presently attached to Technical Mathematics, due to advances in technology and its applications, and thus render the two sides of Mathematics equal. Furthermore, I suggest a reorganization/systematization of School Mathematics into a cognitive network to facilitate students’ understanding of the subject. The final goal is the transition from mechanical execution of rules to better understanding and in-depth knowledge of Mathematics.

Lost in the Rhythm: Effects of Rhythm on Subsequent Interpersonal Coordination

Music is a natural human expression present in all cultures, but the functions it serves are still debated. Previous research indicates that rhythm, an essential feature of music, can enhance coordination of movement and increase social bonding. However, the prolonged effects of rhythm have not yet been investigated. In this study, pairs of participants were exposed to one of three kinds of auditory stimuli (rhythmic, arrhythmic, or white‐noise) and subsequently engaged in five trials of a joint‐action task demanding interpersonal coordination. We show that when compared with the other two stimuli, exposure to the rhythmic beat reduced the practice effect in task performance. Analysis of the behavioral data suggests that this reduction results from more temporally coupled motor movements over successive trials and that shared exposure to rhythm facilitates interpersonal motor coupling, which in this context serves to impede the attainment of necessary dynamic coordination. We propose that rhythm has the potential to enhance interpersonal motor coupling, which might serve as a mechanism behind its facilitation of positive social attitudes.     

Epistemic Warrants and Higher‐Order Theories of Conscious Perception

We present a new account of perceptual consciousness, one which gives due weight to the epistemic commitment of normal perception in familiar circumstances. The account is given in terms of a higher‐order attitude for which the subject has an immediate perceptual epistemic warrant in the form of an appropriate first‐order perception. We develop our account in contrast to Rosenthal's higher‐order account, rejecting his view of consciousness in virtue of so‐called ‘targetless’ higher‐order states. We explain the key notion of an immediate perceptual warrant and show both that it requires the content of the higher‐order attitude to match that of the first‐order perception, and also that it gives a new perspective on the intimate relationship, rightly emphasised by Rosenthal, between consciousness and a subject's testimony as to ‘how it is with her’.
