Use of interactive voice response (IVR) technology in health research with children

This article reports on the feasibility of using interactive voice response (IVR) technology to obtain daily reports of attitudes toward alcohol and tobacco use among children 9–13 years of age. Two studies were conducted. The first was an investigation of the use of IVR technology to obtain daily data from a sample of primary school children over a period of 8 weeks. The second was an extension of the research to a large sample of primary and secondary school children in urban and rural areas who provided daily data over a 4-week period. Retention and compliance rates comparable to those obtained with adults were evident in both studies, supporting the feasibility of this technology with children. The results are discussed in relation to the benefits of this methodology for health research, particularly for studies of sensitive topics conducted with children and adolescents.     

Education,Conflict and the Political: Introduction to the Special Issue

In recent years the French philosopher Jacques Rancière has addressed the predicament of artists and curators who, in their eagerness to convey a critical message or engage their viewers in an emancipatory process, end up predetermining the outcomes of the experience, hence blocking its critical or emancipatory potential. In this essay I consider Rancière’s writing on this topic and draw out the parallels with the predicament of teachers and curriculum designers who have critical and emancipatory objectives. The risk of education that strives for emancipation is that it can become so directive in steering students to the “right” outcomes that it does not leave these students any intellectual room. Rancière’s work is helpful in reminding us that teachers and curricula with explicitly critical, political, emancipatory objectives can defeat their own purposes and become stultifying if they do not leave the student room to use her or his own intelligence.     

EFFECTS OF VIDEO MODELING ON TEACHING BIDS FOR JOINT ATTENTION TO CHILDREN WITH AUTISM

The purpose of this study was to evaluate the effects of video modeling to teach children with autism to initiate bids for joint attention. The video model consisted of a child demonstrating three components of a bid for joint attention with an adult conversational partner: orienting toward the object, emitting a vocal statement, and eye gaze shift toward unique objects in the environment. Results indicated that video modeling alone was effective in teaching all components of joint attention for two of the three children, whereas video modeling plus in vivo prompting was effective for the third participant. Further, bids for joint attention did not generalize across novel items for any of the participants. Results are discussed in terms of the social relevance and validity of the use of video modeling to teach a complex social behavior such as bids for joint attention.

Hospitality and Embodied Encounters in Educational Spaces

This short paper responds to the essays by Shilpi Sinha, Shaireen Rasheed, and Lyudmila Bryzzheva. It considers how racial inequality between teachers and students affects the possibilities of educational hospitality, both in cases of white teachers teaching racialized students and in cases of racialized teachers teaching white students. The response takes a phenomenological turn, considering the relative vulnerability of bodies that encounter each other in educational spaces which, themselves, are not neutral.     

Segregated processing of facial identity and emotion in the human brain: A pet study

Abstract

The brain is organized into segregated areas of relative functional autonomy and specialization. This basic principle of cerebral organization is well documented for cognitive functions that differ drastically from one another, but less so for functions that belong to the same domain, such as face processing. Yet several sources of evidence point to a functional and structural dissociation of various aspects of face processing, as suggested by (1) an analysis of the perceptual and cognitive demands made by the processing of diverse properties conveyed by facial configurations, (2) selective impairment of aspects of face processing in brain-damaged patients, and (3) different localizations of face cells responsive to properties conveyed by faces such as identity and emotion in the monkey's brain. This study used positron emission tomography (PET) and magnetic resonance imaging (MRI) to delineate better the neurofunctional organization of face processing in the human brain, by measuring cerebral blood flow while subjects performed tasks involving the recognition of faces or the recognition of emotions expressed by faces. The results showed segregated processing of facial identity and facial emotion, with the former being performed predominantly in the ventro-mesial region of the right hemisphere including the limbic system, whereas the latter was carried out predominantly in the latter part of the right hemisphere and the dorsal region of the limbic system. This structural organization allows the parallel processing of different information contained in physiognomies and underlies the high efficiency with which humans process faces.
