Dissociation of rapid response learning and facilitation in perceptual and conceptual networks of person recognition
No full textRepetition priming is a prominent example of non-declarative memory, and it increases the accuracy and speed of responses to repeatedly processed stimuli. Major long-hold memory theories posit that repetition priming results from facilitation within perceptual and conceptual networks for stimulus recognition and categorization. Stimuli can also be bound to particular responses, and it has recently been suggested that this rapid response learning, not network facilitation, provides a sound theory of priming of object recognition. Here, we addressed the relevance of network facilitation and rapid response learning for priming of person recognition with a view to advance general theories of priming. In four experiments, participants performed conceptual decisions like occupation or nationality judgments for famous faces. The magnitude of rapid response learning varied across experiments, and rapid response learning co-occurred and interacted with facilitation in perceptual and conceptual networks. These findings indicate that rapid response learning and facilitation in perceptual and conceptual networks are complementary rather than competing theories of priming. Thus, future memory theories need to incorporate both rapid response learning and network facilitation as individual facets of priming
Early response activation in repetition priming:an LRP study
No full textAccording to recent interpretations of repetition priming, response codes are automatically bound to a stimulus and retrieved during successive presentations of the stimulus, hence, affecting its current processing. Despite a solid corpus of behavioural evidence in line with this interpretation, electrophysiological studies have reported contrasting results regarding the nature and the timing of response code retrieval. The present experiment aims to establish at which stage of information processing decision and action codes are retrieved in repetition priming. To this end, the lateralized readiness potential (LRP) was analysed for primed faces to monitor motor cortex activity related to response preparation. Congruent and incongruent responses were obtained by having identical or reversed tasks between study and test. Primed stimuli presented LRP activations with opposite polarities for the two congruency conditions in the time-window 250–300 ms, indicating response-related motor cortex activity resulting from the retrieval of correct and incorrect decision/action codes for congruent and incongruent trials, respectively. This result indicates that decision and action codes bound to a primed stimulus are retrieved at early stages of stimulus processing and that these codes are transmitted to the motor cortex

Caminos icónicos: Gottfried Boehm lector de Martin Heidegger
No full textResumen: El objetivo de esta investigación es analizar la lectura productiva que hace el historiador de arte y filósofo Gottfried Boehm, discípulo de
Hans-Georg Gadamer, del pensamiento de Martin Heidegger. Lejos está Boehm de ser un mero comentador de la filosofía del profesor de
Friburgo o un “heideggeriano”. Tampoco es un cientista social que busca “aplicar” la teoría del arte heideggeriana en la historia del arte.
Mi hipótesis es que la propuesta filosófica de Boehm, sin perder un ápice de originalidad, se sirve de algunos elementos del pensamiento
heideggeriano que le permite desarrollar conceptos centrales. Principalmente me abocaré a lo desarrollado por el historiador del arte
en Wie Bilder Sinn erzeugen, aunque también se hará referencia a otros textos del autor. Rastrearé este diálogo con Heidegger en tres
ideas clave de Boehm: 1. la relación entre la imagen, el mundo y el sentido; 2. la diferencia icónica y; 3. la indeterminación de la imagen.Abstract: The aim of this research is to analyze the productive reading made by the art historian and philosopher Gottfried Boehm, a disciple of
Hans-Georg Gadamer, of the thought of Martin Heidegger. Boehm is far from being a mere commentator on the philosophy of the Freiburg
professor or a „Heideggerian.“ Neither is he a social scientist seeking to „apply“ Heideggerian art theory to art history. My hypothesis is
that Boehm‘s philosophical proposal, without losing originality, makes use of some elements of Heideggerian thought that allow him to
develop central concepts. Mainly I will focus on what was developed by the art historian in Wie Bilder Sinn erzeugen, although reference
will also be made to other texts by the author. I will trace this dialogue with Heidegger on three key ideas of Boehm: 1. the relationship
between the image, the world and meaning; 2. the iconic difference and; 3. the indeterminacy of the image

Angiogenic-regulatory network revealed by molecular profiling heart tissue following Akt1 induction in endothelial cells
No full textAkt is a pivotal signaling molecule involved in the regulation of angiogenesis. In order to further elucidate the role of Akt1 in blood vessel development, a tetracycline-regulated transgenic system was utilized to conditionally activate Akt1 signaling in endothelial cells to examine transcript expression changes associated with angiogenesis in the heart. Induction of Akt1 over the course of 6 weeks led to a 33% increase in capillary density without affecting overall heart growth. Transcript expression profiles in the hearts were analyzed with an Affymetrix GeneChip Mouse Expression Set 430 2.0, which represents approximately 45,000 cDNAs and ESTs. A total of 248 transcripts were differentially expressed between transgenic and control mice (fold change >/<1.8; false discovery rate < 0.1; P < 0.01). A subset of these differentially expressed transcripts included angiogenic growth factors, cytokines, and extracellular matrix proteins. More specifically, these transcripts included VEGF-receptor2, neuropilin-1, and connective tissue growth factor, each of which is implicated in blood vessel growth and the maintenance of vessel wall integrity. Furthermore, these factors may be involved in an autocrine-regulatory feedback system, one believed to promote vessel growth. Knowledge of these and other targets could be used to treat ischemic heart disease, a disease whose broad spectrum of manifestations range from patients with only effort-induced angina without myocardial damage, through stages of myocardial ischemia that are associated with reversible and irreversible impairment in left ventricular function, to states of irreversible myocardial injury and necrosis resulting in congestive heart failure (CHF). © 2008 Springer Science+Business Media B.V
