Properties of curvilinear vection

Approximately linear relationships were observed between contrast, spatial frequency, temporal frequency, or velocity of stimulation and perceived velocity of curvilinear vection—that is, a visually induced self-motion in a curved path. Similarly, linear relationships were also found between the perceived degree of curvature of curvilinear vection and spatial frequency or velocity of stimulation. Since the perceived velocity of curvilinear vection varies with contrast, spatial frequency, temporal frequency, and angular velocity, and the perceived degree of curvature of curvilinear vection varies only with spatial frequency and angular velocity, peripheral vision is not sufficient for computing accurately the curvilinear component of induced self-motion in a curved path. Concurrently, it was shown that the perceived direction of curvilinear vection is not always unambiguously perceived (Sauvan & Bonnet, 1989). Consequently, it is suggested that two different types of visual processing, which involve the peripheral or the central vision, underlie the processing of curvilinear vection.     

Ramadan during a civil war (as reflected in a series of sermons)

In March 1992, the month of Ramadan coincided in Bosnia and Hercegovina with the time between the referendum for the independence of this Yugoslav republic and its recognition by the European Community and the United States. This time was characterized by the transition from a shaky peace into a bloody war. The sermons then given in different mosques in Sarajevo help us to understand better the internal pluralism and evolutions of Bosnian Islam at this time. They also show that some imams used Islam as an impetus to appeasement, and others as an impetus to mobilization. Against the background of extreme tensions between communities, the unanimous perception of Islam as a refuge for the Muslim community encouraged varying re‐Islamization activities.

Differences in dimensionality of electroencephalogram during awake and deeper sleep stages

The nonlinear dynamical systems theory provides some tools for the analysis of electroencephalogram (EEG) at different sleep stages. Its use could allow the automatic monitoring of the states of the sleep and it would also contribute an explanatory level of the differences between stages. The goal of the present paper is to address this type of analysis, focusing on the most different stages. Estimations of dimensionality were compared when six subjects were awake and in a deep sleep stage. Greater dimensionality involves more complexity because the system receives more external influences. If this dimensionality is maximum, we can consider that the time series is a noisy one. A smaller dimensionality involves lower complexity because the system receives fewer inputs. We hypothesized that we would find greater dimensionality when subjects were awake than in a deep sleep stage. Results show a noisy time series during the awake stage, whereas in the sleep stage, dimensionality is smaller, confirming our hypothesis. This result is similar to the findings reached previously by other authors.     

Structure of personality pathology in normal and clinical samples: Spanish validation of the DAPP-BQ

Given that the DSM taxonomy of personality disorders is flawed by severe classificatory problems, the development of alternative classificatory systems, such as the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), has now become a priority. This study examined the internal consistency, second-order factor structure, and criterion validity of a Spanish translation of the DAPP-BQ in two samples: subjects with personality disorder (n = 155) and subjects from the general population (n = 300). Alpha coefficients ranged satisfactorily from .75 to .93. Four second-order factors of Emotional Dysregulation, Dissocial Behavior, Inhibitedness, and Compulsivity were obtained, which were replicable between samples and identical to those reported in the literature. Finally, disordered subjects scored significantly higher than normal subjects on 17 of the 18 DAPP-BQ traits. Some pending issues in the construction of an alternative taxonomy of personality disorders are discussed.     

Migration Related Socio-cultural Changes and e-Learning in a European Globalising Society

OECD figures (1998–2002) reveal a sharply increasing flow of foreign workers into European countries. Ethnic diversification has become a generalized matter of fact. At the same time, rapidly developing technology and ‘intellectual globalization’ processes—the world wide web—have also become a reality. This complex cluster of changes has an impact on the perceptions of the self and of the other. Multilayered belongings and paradoxical meanings enter into interethnic relations in sometimes most surprising and unpredictable ways from outside of the boundaries of local communities. But the developments also create new and very positive opportunities for education/schooling and social cohesion. The paper critically examines this changing context and also Europe’s educational responses to the new challenges: the European Socrates programme, the initiatives in the field of intercultural citizenship education and the issue of combating deprivation.

Semantic numerical representation in blind subjects: the role of vision in the spatial format of the mental number line

Does vision play a role in the elaboration of the semantic representation of small and large numerosities, notably in its spatial format? To investigate this issue, we decided to compare in the auditory modality the performance of congenitally and early blind people with that of a sighted control group, in two number comparison tasks (to 5 and to 55) and in one parity judgement task. Blind and sighted participants presented exactly the same distance and SNARC (Spatial Numerical Association of Response Codes) effects, indicating that they share the same semantic numerical representation. In consequence, our results suggest that the spatial dimension of the numerical representation is not necessarily attributable to the visual modality and that the absence of vision does not preclude the elaboration of this representation for 1-digit (Experiment 1) and 2-digit numerosities (Experiment 2). Moreover, as classical semantic numerical effects were observed in the auditory modality, the postulate of the amodal nature of the mental number line for both small and large magnitudes was reinforced.     

Negative cognitive emotion regulation as a predictor of adolescent heart rate variability and entropy under social stress

ABSTRACT

Background and Objectives: Negative cognitive emotion regulation (ER) strategies are particularly important within the framework of anxiety problems amongst youths and how they cope with stressful events. The aim of this study was to examine the associations between both negative and positive ER style and cardiac regulation under stressful conditions.

Design: Eighty-nine adolescents (M?=?13.31 years, SD?=?0.68, 44.94% girls) were exposed to a socially relevant stress induction protocol.

Methods: Participants’ emotion regulation strategies were assessed and their cardiac function was recorded.

Results: A negative ER style predicted heart rate (HR) entropy at the stressful stage after controlling for anxiety scores. In addition, heart rate variability reactivity and recovery and HR entropy recovery were larger (p?<?.05) in the low negative ER style group (n?=?16) than in the high negative ER style group (n?=?23).

Conclusions: Results suggest that individuals with a highly negative ER style have diminished autonomic flexibility.
