    Conscious access overflows overt report

    Block proposes that phenomenal experience overflows conscious access. In contrast, we propose that conscious access overflows overt report. We argue that a theory of phenomenal experience cannot discard subjective report and that Block's examples of phenomenal "overflow" relate to two different types of perception. We propose that conscious access is more than simply readout of a preexisting phenomenal experience

    Bias-Dependent Generation and Quenching of Defects in Pentacene

    Full text link
    We describe a defect in pentacene single crystals that is created by bias stress and persists at room temperature for an hour in the dark but only seconds with 420nm illumination. The defect gives rise to a hole trap at Ev + 0.38eV and causes metastable transport effects at room temperature. Creation and decay rates of the hole trap have a 0.67eV activation energy with a small (108 s-1) prefactor, suggesting that atomic motion plays a key role in the generation and quenching process.Comment: 10 pages, 3 figure

    Quelle rĂ©gulation pour l’arrĂȘt d’un protocole de recherche clinique de thĂ©rapie gĂ©nique somatique ? État des lieux auprĂšs des cliniciens-chercheurs europĂ©ens

    Depuis 2002, le dĂ©bat sur les risques associĂ©s Ă  la thĂ©rapie gĂ©nique est initiĂ© suite Ă  l’annonce que deux enfants inclus dans un essai thĂ©rapeutique impliquant une thĂ©rapie gĂ©nique ont dĂ©veloppĂ© des effets indĂ©sirables important. En Janvier 2005, le dĂ©bat sur les risques reprit suite Ă  l’interruption du protocole sur les enfants bulle du Pr Fischer Ă  l’hĂŽpital Necker de Paris. Nous avons donc Ă©tudiĂ© le processus impliquĂ© ainsi que la rĂ©flexion Ă©thique associĂ©e aux dĂ©cisions d’arrĂȘt de protocole de recherche. Notre travail a Ă©tĂ© menĂ© par une Ă©quipe pluridisciplinaire combinant chercheurs en santĂ©, gĂ©nĂ©ticiens et Ă©thiciens. Nous avons Ă©tudiĂ© la participation des chercheurs, des patients, des institutions officielles, des comitĂ©s d’éthique ainsi que des associations de patients dans le processus de dĂ©cision d’interruption d’un protocole de recherche.Nous avons Ă©galement analysĂ© les critĂšres jugĂ©s les plus pertinents dans l’arrĂȘt d’un protocole de recherche. Enfin nous avons analysĂ© le point de vue des personnes directement impliquĂ©es dans la thĂ©rapie gĂ©nique au moyen d’un questionnaire. Toutes les personnes contactĂ©es ont prĂ©sentĂ© un poster de recherche au congrĂšs de la SociĂ©tĂ© EuropĂ©enne de ThĂ©rapie GĂ©nique. 62 personnes d’autant d’équipes de recherche diffĂ©rentes, de 17 pays, sur les 350 contactĂ©s ont rĂ©pondu. Selon eux, la dĂ©cision d’arrĂȘt d’un protocole de recherche doit ĂȘtre prise suite Ă  une consultation des chercheurs, des patients, du ministĂšre de tutelle, d’une agence nationale de rĂ©gulation ou d’un comitĂ© d’éthique ; la lĂ©gitimitĂ© Ă©tant accordĂ©e Ă  des dĂ©cisions prises en commun par les chercheurs, les patients et les comitĂ©s d’éthique. Les incidents sĂ©rieux et de façon plus surprenante, les incidents moins graves sont jugĂ©s comme Ă©tant des critĂšres suffisants pour interrompre un essai. Nous avons fini par analyser les consĂ©quences Ă©thiques, telles que balance bĂ©nĂ©fice/risque, processus de rĂ©gulation ou responsabilitĂ©, de ces critĂšres sur l’arrĂȘt d’un protocole de recherche.In 2002, the debate on the risks of gene therapy was initiated following the annoucement that two children included in a clinical trial developed serious adverse effects. In January 2005, the debate was reignited following the interruption of the “bubble kids protocol” at the HĂŽpital Necker in Paris. We have thus investigated the ethical stakes involved in decisions to stop protocols. This work was carried out by a multidisciplinary team combining ethics researchers and geneticists. We studied the specific participation of researchers, patients, official institution, ethics committees and patient associations in the processes that can lead to an interruption of trial.We also analysed the criterion judged most relevant for halting a trial. Finally, we analyzed the perspective of the actors implicated directly in the provision of gene therapy, by means of a questionnaire. All the individuals contacted had presented a scientific poster at the European Society of Gene Therapy. 62 out of 350 persons, from 17 countries, responded to our questionnaire. According to these respondants, decisions to stop a trial should be taken after consultation with researchers, patients, the ministry, national agencies or ethics committees. Legitimacy was accorded to joint decision-making by researchers, patients and committees. Serious incidents, and surprisingly less serious incidents, clearly emerge as criterion for stopping a trial. We conclude by analyzing the ethical consequences, such as risk/benefit ratios, regulatory processes and responsibility, associated with these criterions and decisions to stop a trial

    Longer fixation duration while viewing face images

    The spatio-temporal properties of saccadic eye movements can be influenced by the cognitive demand and the characteristics of the observed scene. Probably due to its crucial role in social communication, it is argued that face perception may involve different cognitive processes compared with non-face object or scene perception. In this study, we investigated whether and how face and natural scene images can influence the patterns of visuomotor activity. We recorded monkeys’ saccadic eye movements as they freely viewed monkey face and natural scene images. The face and natural scene images attracted similar number of fixations, but viewing of faces was accompanied by longer fixations compared with natural scenes. These longer fixations were dependent on the context of facial features. The duration of fixations directed at facial contours decreased when the face images were scrambled, and increased at the later stage of normal face viewing. The results suggest that face and natural scene images can generate different patterns of visuomotor activity. The extra fixation duration on faces may be correlated with the detailed analysis of facial features
