Methods for studying unconscious learning
2005
One has to face numerous difficulties when trying to establish a dissociation between conscious and unconscious knowledge. In this paper, we review several of these problems as well as the different methodological solutions that have been proposed to address them. We suggest that each of the different methodological solutions offered refers to a different operational definition of consciousness, and present empirical examples of sequence learning studies in which these different procedures were applied to differentiate between implicit and explicit knowledge acquisition. We also show how the use of a sensitive behavioral method, the process dissociation procedure, confers a distinctive adva…
A Functional Near-Infrared Spectroscopy Examination of the Neural Correlates of Cognitive Shifting in Dimensional Change Card Sort Task
2020
This study aims to examine the neural correlates of cognitive shifting during the Dimensional Change Card Sort Task (DCCS) task with functional near-infrared spectroscopy. Altogether 49 children completed the DCCS tasks, and 25 children (Mage = 68.66, SD = 5.3) passing all items were classified into the Switch group. Twenty children (Mage = 62.05, SD = 8.13) committing more than one perseverative errors were grouped into the Perseverate group. The Switch group had Brodmann Area (BA) 9 and 10 activated in the pre-switch period and BA 6, 9, 10, 40, and 44 in the post-switch period. In contrast, the Perseverate group had BA 9 and 10 activated in the pre-switch period and BA 8, 9, 10 in the pos…
The Mona Lisa effect: Neural correlates of centered and off-centered gaze
2014
The Mona Lisa effect describes the phenomenon when the eyes of a portrait appear to look at the observer regardless of the observer's position. Recently, the metaphor of a cone of gaze has been proposed to describe the range of gaze directions within which a person feels looked at. The width of the gaze cone is about five degrees of visual angle to either side of a given gaze direction. We used functional magnetic resonance imaging to investigate how the brain regions involved in gaze direction discrimination would differ between centered and decentered presentation positions of a portrait exhibiting eye contact. Subjects observed a given portrait's eyes. By presenting portraits with varyin…

Forensic considerations on violent parasomnias during lifespan
2018
Nocturnal parasomnias are a group of sleep complex manifestation that don't alter the sleep macrostructure, but when persistent during adulthood may be assume violent aspects with relevant forensic implications about the guiltiness.
Immunohistochemical Investigation in Experimental Intracerebral Hemorrhage (ICH) and Its Correlation with Findings in Clinical Studies
1986
Since McKissock et al. 1961 investigated the effects of surgical and conservative treatment of ICH on final outcome it is well known that systemic hypertension worsens the prognosis of this serious cerebrovascular disease. Our own studies on this problem have revealed differences in final outcome, as well as in level of consciousness after ICH, between normotensive and hypertensive patients. Whilst 30.6% of the normotensive patients died, 48.1% of the hypertensive patients had a lethal outcome.
The development of reflective learning in the context of health counselling and health promotion during nurse education.
2001
The development of reflective learning in the context of health counselling and health promotion during nurse education Aims and background. The purpose of this follow-up study was to describe the development of reflective learning of 16 student nurses in the context of health counselling and promotion during clinical training of a 3-year nursing education programme in two Finnish polytechnics. The first aim was to analyse the levels of reflectivity in the student nurses’ reflections on their videotaped counselling situations. The second aim was to explore the qualitative features of the reflective health counselling learning process in the context of health promotion. The theoretical backg…
Ecosistemas locales de aprendizaje ante la globalización tecnológica. Retos de los modelos educativos digitales pospandemia
2021
La educación frente a la covid-19 ha puesto en práctica una infinidad de respuestas, todas urgentes, tentativas, generadas por ensayo y por error, y todavía pendientes de validación. Para comprender mejor el impacto de estas respuestas, el presente artículo defiende, partiendo de la teoría de los ecosistemas de aprendizaje, la necesidad de investigar cómo han influido las tecnologías de ámbito global en la construcción de experiencias locales de aprendizaje. Además, pone de manifiesto la necesidad de estudiar qué tipo de apoyo tanto teórico como práctico se requiere para reconducir los posibles efectos nocivos de la introducción de la tecnología de emergencia. A tal efecto, se describen las…
Non-naturalistic Neuroethics for Moral Neuroeducation
2019
The aim of this chapter is to examine a series of key approaches towards identifying an appropriate neuroethics for moral neuroeducation. I begin by highlighting the shortcomings of neuroeducation models that side-line ethical issues. Neuroscience has contributed decisively to the knowledge of the brain mechanisms involved in teaching and learning processes. However, often only one form of learning, that based on instrumental subjects (mathematical calculation or reading), is taken into account. Undoubtedly, neuroeducational advances in this area have been very beneficial, but by focusing on education in strictly instrumental terms, the principles and ethical values that should structure ed…
Everyday Discourses on Disability: A barrier to successful disability policy?
2006
Concerning the role of everyday discourses on disability in the realiza- tion of disability policy, this qualitative study focuses on the problematic meanings of disability and of being disabled in 45 fictional texts about a disabled woman and man (21/24) written by non-disabled graduate students and welfare professionals. The traditional individualising un- derstanding of disability was dominant in the discourses of the texts, especially in those about the disabled women which also repeated oth- ering discourses. The socio-environmental understanding was echoed as well, but mainly in the texts about the disabled men. I discuss the possible practical consequences of the polarised and gender…
