Transcranial Direct Current Stimulation (tDCS) over the Intraparietal Sulcus Does Not Influence Working Memory Performance

Mixed results of the impact of transcranial direct current stimulation (tDCS) on working memory have been reported. Contrarily to previous studies who focused mainly on stimulating the dorsolateral prefrontal cortex, we modulated the left intraparietal sulcus (IPS) area which is considered to support attentional control aspects of working memory. Using a within-participant experimental design, participants completed three different conditions: anodal stimulation of the IPS, cathodal stimulation of the IPS, and sham stimulation of the IPS. Both visual and verbal working memory tasks were administered. In the visual task, participants had to memorize a random set of colored figures. In the verbal task, participants had to memorize a string of letters. Working memory load was manipulated in both tasks (six figures/letters vs. two figures/letters). No significant differences in accuracy or reaction time between the anodal, cathodal and sham conditions were found. Bayesian analysis supported evidence for an absence of effect. The results of the present study add to the growing body of contradictory evidence regarding the modulatory effects of single session tDCS on working memory performance.

Vigilance for threat: effects of anxiety and defensiveness

Eysenck’s (1997) theory that attentional biases for threat vary as an interactive function of trait anxiety and defensiveness was tested using a visual probe task. Two stimulus exposure conditions were used to explore a secondary issue concerning attentional allocation over time. Results indicated that, among high trait anxious participants, only those with low levels of defensiveness showed vigilance for threatening faces presented for 500 ms. They also showed an attentional preference for neutral faces, relative to happy faces, irrespective of exposure condition. This pattern was reversed in high trait anxious participants with high levels of defensiveness, who showed an attentional bias towards happy faces (relative to neutral faces) under both exposure conditions. The findings are discussed in relation to their implications for (a) the significance of measures of defensiveness for the conceptualization of high trait anxious individuals, and (b) the status of anxiety-related biases at different stages of information processing.     

Graveyards: Russian ritual and belief pertaining to the dead

The age-old tradition of feasting the dead has been maintained by Russian populations for well over five centuries. Graveyards hold a special place both in traditional Orthodox faith and in the lives of Russians and others in the city of Narva, Estonia. The tradition of feasting the dead for three, nine and forty days after death, can be traced unbroken to pre-Christian Rus’. Details may vary, but always the soul of the deceased must battle its way out of the body and then spend time in both heaven and hell. While this journey is occurring, the living must remember the dead, helping their souls during this period of travail. Even a final feast one year after the death of the individual does not end the relationship between the living and the deceased, for the graves are still visited on a regular basis as a sign of respect to the dead, who are potential saints in the Russian Orthodox tradition. This ‘saintly’ land — Russian graves — defines homeland and roots the population to a new area. By examining the importance of graveyards to Russians, to the ethnic Komi of Northern Russia, and other Eastern Europeans, I demonstrate that a sense of place is maintained in these rituals of daily life.     

Psycholinguistic norms for action photographs in French and their relationships with spoken and written latencies.

A set of 142 photographs of actions (taken from Fiez & Tranel, 1997) was standardized in French on name agreement, image agreement, conceptual familiarity, visual complexity, imageability, age of acquisition, and duration of the depicted actions. Objective word frequency measures were provided for the infinitive modal forms of the verbs and for the cumulative frequency of the verbal forms associated with the photographs. Statistics on the variables collected for action items were provided and compared with the statistics on the same variables collected for object items. The relationships between these variables were analyzed, and certain comparisons between the current database and other similar published databases of pictures of actions are reported. Spoken and written naming latencies were also collected for the photographs of actions, and multiple regression analyses revealed that name agreement, image agreement, and age of acquisition are the major determinants of action naming speed. Finally, certain analyses were performed to compare object and action naming times. The norms and the spoken and written naming latencies corresponding to the pictures are available on the Internet (http://www.psy.univ-bpclermont.fr/~pbonin/pbonin-eng.html) and should be of great use to researchers interested in the processing of actions.     

Intrinsic,identified, and controlled types of motivation for school subjects in young elementary school children

Background. There are two approaches to the differential examination of school motivation. The first is to examine motivation towards specific school subjects (between school subject differentiation). The second is to examine school motivation as a multidimensional concept that varies in terms of not only intensity but also quality (within school subject differentiation). These two differential approaches have led to important discoveries and provided a better understanding of student motivational dynamics. However, little research has combined these two approaches. Aims. This study examines young elementary students' motivations across school subjects (writing, reading, and maths) from the stance of self‐determination theory. First, we tested whether children self‐report different levels of intrinsic, identified, and controlled motivation towards specific school subjects. Second, we verified whether children self‐report differentiated types of motivation across school subjects. Sample. Participants were 425 French‐Canadian children (225 girls, 200 boys) from three elementary schools. Children were in Grades 1 (N=121), 2 (N=126), and 3 (N=178). Results. Results show that, for a given school subject, young elementary students self‐report different levels of intrinsic, identified, and controlled motivation. Results also indicate that children self‐report different levels of motivation types across school subjects. Our findings also show that most differentiation effects increase across grades. Some gender effects were also observed. Conclusion. These results highlight the importance of distinguishing among types of school motivation towards specific school subjects in the early elementary years.     

Challenging the Limits of Critique in Education Through Morin’s Paradigm of Complexity

The position adopted in this paper is inspired by Edgar Morin’s paradigm of complexity and his critique of scientific and philosophical forms of reductionism. This paper is based on research focusing on the diversity of conceptions of critique developed in academic discourses. It aims to challenge the fragmentation and the reduction framing the understanding of this notion in educational sciences. The reflection begins with the introduction of some of Morin’s assumptions concerning the paradigm of complexity. The next section provides a definition of the idea of critique and explores some limits associated with contemporary references framing this notion. Theories of critique are at the core of several educational theories. Based on the literature identified in French-speaking and English-speaking critical traditions in education, several factors determining the way the idea of critique is reduced in education are highlighted. Stressing the tacit character of those variables challenges the limits of traditional conceptions of critique in contemporary education. The position adopted denounces therefore the fact that the current development of theories of critique in education does not provide a framework considering more systematically their conditions of emergence, their own limitations, as well as the antagonistic, complementary and contradictory relationships, which connect them to one another. Based on this position, this paper finally suggests that a distinction be made between “hypocritique” and “hypercritique” as a semantic artifact, stressing the importance of challenging existing theories of critique in education according to the level of complexity that one may attribute to them.
