Somatosensory Illusions Elicited by Sham Electromagnetic Field Exposure: Experimental Evidence for a Predictive Processing Account of Somatic Symptom…
2020
OBJECTIVE According to the predictive processing theory of somatic symptom generation, body sensations are determined by somatosensory input and central nervous predictions about this input. We examined how expectations shape predictions and consequently bodily perceptions in a task eliciting illusory sensations as laboratory analogue of medically unexplained symptoms. METHODS Using the framework of signal detection theory, the influence of sham Wi-Fi on response bias (c) and somatosensory sensitivity (d') for tactile stimuli was examined using the somatic signal detection task (SSDT). A healthy student sample (n = 83) completed the SSDT twice (sham Wi-Fi on/off) in a randomized order after…
Communication et médiation par le toucherdans quelques expositions de sciences : Limites et contraintes dans l’expérience des visiteurs
2016
This communication deals with the “general public” of visitors to a number of interactive exhibits that accord a direct or indirect role to the sense of touch in knowledge mediation and interpretation. The role of touch is discussed in terms of its limitations and constraints in communication situations. The social mobilizations of touch are not immediately evident; what are the conditions under which visitors actually use touch in experiencing an exhibit? What connections with other signifiers are the most conducive to reception? This qualitative research relies on observation and interviews. Apprehension of interactive objects appears to be dependent on the surrounding setting of sociabil…

A Model for the Study of Sheath Currents in Medium Voltage Cables for Industrial Application
2020
In this paper, the implementation of a simulation model for studying the effect of cross-bonding of metallic sheaths and/or non-magnetic armor of single-core medium voltage cables in the same circuit is discussed. With the use of single-core cables, the resistive losses due to the induced circulating currents in cable sheaths or armors causes an increase of cable temperature that reduces its ampacity. In addition, the risk of electric shock due to induced voltages may be present if a person is exposed to the armor/sheath at the unbounded end. For this reason, special bonding techniques are used to significantly reduce these currents. The authors have implemented a model that could be used t…
National Social Life, Health, and Aging Project (NSHAP): Round 1, [United States], 2005-2006
2007
The National Social Life, Health and Aging Project (NSHAP) is the first population-based study of health and social factors on a national scale, aiming to understand the well-being of older, community-dwelling Americans by examining the interactions among physical health, illness, medication use, cognitive function, emotional health, sensory function, health behaviors, and social connectedness. It is designed to provide health providers, policy makers, and individuals with useful information and insights into these factors, particularly on social and intimate relationships. The National Opinion Research Center (NORC), along with Principal Investigators at the University of Chicago, conducte…
T9+HUD: Physical Keypad and HUD can Improve Driving Performance while Typing and Driving
2016
We introduce T9+HUD, a text entry method designed to decrease visual distraction while driving and typing. T9+HUD combines a physical 3x4 keypad on the steering wheel with a head-up-display (HUD) for projecting output on the windshield. Previous work suggests this may be a visually less demanding way to type while driving than the popular case which requires shifts of visual attention away from the road. We present a prototype design and report first results from a controlled evaluation in a driving simulator. While driving, the T9+HUD text entry rate was equal compared to a dashboard-mounted touchscreen device, but it reduced lane deviations by 70%. Furthermore, there was no significant di…
La marque ou une mention innovante permet-elle de compenser l'impossibilité de toucher le produit par les consommateurs ?
2015
Packaging or methods of distance selling prevent consumers from touching the products and therefore from evaluating them properly. Thus the aim of this research is to observe whether extrinsic information, such as brand or innovative cue, can compensate this lack of sensory information and so improve the hedonic evaluation. An experiment conducted on 110 subjects with two fabrics shows that consumers evaluate them more positively when they observe them with an extrinsic information than when they observe them without this information, and that this improvement is greater than that obtained when we allow them to assess the fabrics by the touch in addition to the mere sight.
Rules of Engagement: Family Rules on Young Children’s Access to and Use of Technologies
2018
This chapter reports on a study conducted in seven countries in which young children’s (aged under 8) digital practices in the home were examined. The study explored family practices with regard to access to and use of technologies, tracing the ways in which families managed risks and opportunities. Seventy families participated in the study, and interviews were undertaken with both parents and children, separately and together, in order to address the research aims. This chapter focuses on the data relating to parental mediation of young children’s digital practices. Findings indicate that parents used a narrow range of strategies in comparison to parents of older children, primarily becau…
